Hi All. Just to add a little more info to this great video. I recorded in 10bit 4K 4.2.2 H.265 (the XAVC HS mode) on my A74. I put it on a tripod in a 72 degree F room. In 24P it recorded for 1 hour and 53 minutes when the battery died. No overheat warning or shutdown. After a long cooldown. I used the same codec H.265 4.2.2 4k, but at 60fps on a tripod in the same 72 degree F room and recorded for 1 hour and 42 minutes - which is when the battery died. No overheat warnings or overheat shutdown. Maybe the H.265 helped with the longer 60fps record time, or maybe it was because I had it on a tripod. Not sure. I also tried the 10bit H.265 HS 4.2.0 Codec in 24fps and 60fps and got essentially the same times as the 4.2.2 H.265 HS times. I normally record in the HS 4.2.0 mode, as I like the smaller file sizes, it edits easily on almost any computer ( since it's the 4.2.0 Codec, and most Macs and PC's have hardware optimization for that particular H.265 Codec). I always record in Slog 3, and I have yet to be able to discern any color grading flexibility difference between the 4.2.2 codec or the 4.2.0 codec in any footage I have ever shot. I haven't seen any limitation of the 4.2.0 10 bit H.265 HS codec in any color grading pushes, Noise Reduction, or effects. It all grades just as well as the 4.2.2. Hope this is helpful.
Great info. Thanks for sharing! Gunna pin this to the top
Great comment and thanks for adding that. I’d have to agree that I always record in H.265 4.2.0 SLOG3 and I honestly can’t see any distinguishable difference in color grading flexibility. Not to mention that 90% of the viewers out there are watching on some social media platform.
Which memory card did you use? I can record for only 10 minutes using the 4K 25 FPS 4.2.0 codec on the SanDisk Extreme Pro card (300MB/s read speed and 260MB/s write speed. included in the V90 class). It heats up and shuts down immediately.
@@abdullahharun2640 I used a ProGrade 256GB V90. Are you sure you have your Camera Heat setting on High?
@@RockyColaFizz Yes, now I set the heat setting to high and it was able to record long videos. but the machine got too hot. It got hot enough to burn my hand.Does this overheating cause any damage to the camera? I read about this on Facebook.
Thanks for this video. I had this type of overheating expirance my first few days with the camera but after changing the shutdown settings to high this has been a none issue. At the end of the day these cameras are incredible tools that have their limitations just like EOR R 5s or 6s. The main idea of shooting slow-motion is to have the option available not to use it continuously for a whole shoot. I shoot commercial, event, and film work. Each other these areas require a different type of tool for the job. For those watching this please remember to choose the tool or camera you invest in based on what you are creating. Is it film, youtube, commercial photos? Whatever it is, in my opinion this camera is one of the best tools I have ever used for a variety of jobs. Anyways, that's my two cents you all have a great day.
To prevent overheating on my A7III, I set the heat tolerance to high, popped the screen open a bit, and put a small piece of tape over the eyepiece to trick the camera into shutting off the screen. I've been able to record continuously for four hours on a tripod (with short breaks to restart the camera when swapping out batteries and SD cards, and after that infernal 30-minute limit).
Is that true?
Nice! your testing answers all my questions about recording
That’s some handy info and has no negative effect on how I shoot. I already assumed the flip out screen would make a difference so thanks for confirming.
Thanks for putting this test together. I have the Sony A7IV which I receieved on the 30th of december and this thing heats up and shuts down. I have a A7III and never changed the heat setting from standard to high and never had any issues. your milage may be different but my A7IV gave me the hot icon while moving through the menus without even recording. I see a lot of people saying set the temp setting to high, but during my tests it will power down at 108-110f which is pretty darn warm. Turn the mode dial to photo and it will never heat up, change the dial to video and the beast of a processor is doing something and causes it to heat up. If I can get mine to power down on standard heat setting at 108F I can just imagine how hot the body can get if the setting is set to high
.
Hi Chris,
Good content as always.
I shared in other posts that I have a lot of experience using the R5 and its overheating issues.
The culprits comes from lack of applying thermal physics. Design and weatherproof and/or waterproof (like action cams) and shoot in high frame rates, high resolutions, 4:2:2 10bit codecs will lead to overheating.
What gets me is it seems these engineers haven’t learned to design it for thermal physics such as:
- using inductive bodies such as Magnesium alloy bodies
- passive cooling using copper heat sinks
- active cooling fans as done first on Pana S1H, then FX3, Z9, and now R5C
Here are the culprits that generates the most heat:
1) The ISP and image sensors are the biggest culprits, followed by the LCD screen, which all residues as neighbors. This is why Tilta built the fan to flush against the back of the LCD when the LCD is opened. The active cooling fan helps a lot and I am able to get double the times on the R5 shooting times set by Canon.
2) The next ones are the memory cards and batteries. On the R5, I use a grommet to put inside the hole to fake that the memory card door is closed to keep it open. For the battery, I use a dummy battery. For the A74, the memory card door can be left opened without inserting any grommets.
3) wifi, bluetooth, lens compensation, GPS, NFC, and other features will generate heat can be turned off using the “airplane mode”
There are essentially two types of recording that I do:
1) short form recording (under an hour and run and gun situations):
- flip out LCD (as Chris mentioned in this video)
- turn power settings to high temp (as Chris mentioned in this video). This is what Sony calls tripod mode as for consumer protection for the hands. The default setting is standard for handheld. Hot to the hand or “hand hot” is different for each person but can range from above 40degC. In US, I believe the law is 53degC and above. In UK and Europe, I think it is 48degC and above
- turn LCD screen brightness down if feasible (may not be option outdoor in sunny day)
- use Tilta fan on high setting (loud but if you mic up and not vlogging, you’re fine)
- use dummy battery. Chris, saw that you use the Anton Bauer Tilton Base but Core SWX has matched it with a 70Wh but better wider QR base plate, has a V-mount adapter with 1/4” female screw to attach to tripod, cage, or to lights and other accessories, and best of all, it can be piggy backed or daisy chain to have multiple batteries to last all day. You just need to be careful which power port you can plug external recorders and camera dummy batteries into as the output is usually 8.4V and the P/D-taps are 12-16V. You will short out your main board which has the power management and other components.
2) long form recording:
- use an external recorder such as the Ninja 5/5+, BM Video Assist, SmallHD, etc. and record externally only. If you also record internally, you will be faced with same overheating issues.
So Sony, Canon, Pana, and any cameras that has a small body and try to design it to be weatherproof and also allow to shoot at high resolutions (4K and above or oversampled), high frame rates (60/120fps), and taxing encoding codecs such as 4:2:2 10bit All-I H.264, will have some sort of overheating at some point.
The comments why Sony’s APSC cams and A73 didn’t overheat does not understand that they all were using low end encoding codecs on 8bit 4:2:0, weren’t capable of 60/120fps high frame rates, and not shooting at 7K oversampled 4K.
Anyhow, sorry for the long rant!
thanks for the feedback, great info here for people
Hey Chris, thank you for this very detailed video. It surely helps the rest of us considering this camera.
Great tests man! Bummer that it overheats, but glad it's only in very specific scenarios.
This video is sufficiently reassuring :) thanks Chris!
Great test1 Thanks! Very helpful!
Thanks Chris! Great video 📸
Great job on the tests Chris! My respect for testing this way I know how incredibly time consuming it is. I think most people that are having an issue are keeping the screen closed and not changing the temp shut off setting. Well done!
Thanks Jake! I got about 3 hours in and regretted starting this video.. had to finish it though haha.
Does it overheat in 1080p
Perfect Video! Exactly what i wanted to know.
Always informative. Thanks.
Thank you for taking the time to do this test, as well as your friend.
Do you think that's why Sony didn't enable 4K 60p full-frame? Downsizing from 7K to 4K at 60p would cause it too overheat really fast?
Realy helpful many thx for this.
Very insightful! With screen open, it seems to offer pretty competitive recording times before overheating.
Very helpful, Chris..thank you. My brand-new A7IV overheated and shut down yesterday while I wasn't even recording (I was just sorting my menus out for about 30-45 mins).
Useful video Chris!
Great video, I haven't seen such a thorough test anywhere 👌
In a german video I saw somebody complaining that it overheats quicker if recording externally in an Atomos Ninja V. I find it surprising because that's supposedly the solution for the overheating of my R6...
intresting. that with NINJA V!
Excellent job on this. I just recently shot a wedding with the Sony A7IV and did a vlog about it on my channel. I had no issues with overheating, but at the same time it was cold AF outside (literally snowing). I also was mainly only doing photography and I was shooting it along side my Z6ii. So that probably helped as well. But now I know I’m the future that if I do something more video centric to look out for overheating. Yikes 😬
Landscape/sitting wildlife/street & video with vlogs and no serious investment to either glass which one you taking bro? Z6ii or the a7iv with the nikkor 24-70f2.8 s and the gm 24-70f2.8 ii
Thank you so very much! Enjoyed thoroughly the whole piece!
Yet, there are 2 questions:
1. Can you film, providing energy to the camera with USB-C card, - maybe it will remove a bit of heat?
2. Does this camera record the video before "dying"? My very old and cheap Sony A5100 does record everything, while my FF Nikon 610 dies and looses all what;s been filmed, - too bad!
IS there any way to know in advance, if a particular camera "writes everything" or it does, before the "death of the battery" ??
Thanks for sharing your findings! I tend to shoot outdoors in warmer climates with a gimbal. I am hoping overheating will not be too much of an issue especially, since I keep the screen closed with the screen visible.
How has it been for you? Looking at a similar situation myself
Excellent video. Did you set the temperature to high in the tests? With temperature to standard i have recorded 20 minutes and with temperature to high i have recorded until the battery exhausted (1 hour and 20 minutes) for 4k 8bit
Hey thanks for the excellent content & the info on the kondor blue, I have purchased one 🙂. I’m looking for the best memory card to pair with my a7iv, I wanted to see what’s your recommendation?
Thanks in advance
Hi, thanks to share your interesting video. I will have to use Sony A7 IV enough often in Africa. Do you think the Sony A7 IV will be sturdy enough to withstand the heat, dust and humidity? Thank you
Hey Chris, incredible video! My A7 IV shut down today and my flip out screen was closed. I'll keep it open next time. Cheers! 👍
Hi Chris, thanks for your video. I'm considering switching from my Panasonic S5 for indoor concert shooting that does does a really good job with no overheating. I need a reliable sony camera for an hour and a half video shooting in 4k 25p and I wonder if I should buy the A7iv or the FX30 since I don't have a the budget for the FX3 for this kind of shoot. Any recommendations? Thanks a lot.
Thxs! Can you share results with a dummy battery?
Congrats on 100k Chris!
Thankyou!
Nicely done, this video is like tailored for me. I was just thinking about overheating and using third party batteries.
Thank you!
As a Sony a7II user and aspiring videographer I am planning to upgrade. The main reason is video AF which is a torture if you use a7II. You can almost see battery percentage dropping while waiting for nailed focus 😒 And charging while recording with a7II is impossible, only dummy battery is a solution.
If you upgrade to the A74 you'll be in a whole new world if your shooting video, way better camera.
Under what settings are the options to change to continuous recording? I set up my rig to record a 45 minute video & walk away. Only to find later its powered off & only recorded about 20 minutes.
I wonder if the canon R6 behaves in the same way? Would be nice to see if the screen position affects its running time.
Thank you so much for this!
great informative video!
Glad to see someone with a significant following talking about this. I didn't see any reviewers with pre-release models suggest there were overheating issues under normal circumstances, nor discuss the matter in this depth.
My first recording on the A74 lasted just less than 9 minutes, then overheated. I was shooting 4k 25fps XAVCs 10bit 422, with the auto power off set to high, and I was indoors with the heating on. I believe it overheated because I was intensively changing settings whilst recording. I wasn't doing an overheating test, just cycling through the picture profiles, playing with the AF tracking and constantly changing exposure settings to test the 'second base' ISO' in different profiles.
I've since done overheating tests where I've left the camera recording without playing with the settings, and I've not had any problems. On these tests I recorded for over 90 minutes, with and without the screen folded out, until a 128gb filled up. For one test, in the last few minutes of card space, I tried to make the camera overheat. It didn't overheat, but I noticed as soon as I switched to 64,000 ISO (which I realistically wouldn't shoot at), the overheating warning appeared, and disappeared as soon as I went back down in ISO.
Thanks for sharing this Chris!
Jordan Drake mentioned overheating issues with his pre-release A7 IV.
Super helpful! 🙌🏻
thanks for the info
Thanks! What about bigger objectives?
May i ask you that: if i charge by type C, is it fine for my a7 Iv - or i need to use the external charge.
Thank you
I love that you got your camera from Henry’s! I just got mine from there - It’s a Canadian family owned business and love to see them competing with the big dogs!
Fantastic, thanks for the hints and insights. Just a side question though: what card type do you use for prolonged tests? CFExpress or UHS-II?
Great question. CFExpress could solve the problem? Idk
need help. i updated my sony a7iv to version 2.0 and now it shuts down in 15 minutes. would it be possible to downgrade?
Looking to do sports videography. Outdoors in heat of summer. I’m assuming this camera is not the best for that?
Good test. Well done.
Thank you!
What if the screen is closed altogether. Not using the view from that screen. Utilizing eye viewfinder or external monitor instead?
Learned a lot. Thanks bro. Btw what is the cover of your camera that looks like a flower?
Great video. What about doing a test with USB Power, this could be useful for people doing live multicamera streaming and recording in camera.
How about if i use the anton bauer base to power the camera? Would it still overheat?
I am a new sony user. Had been using canon camera all this while ? Can I know if this only happens if you 'record' or the camera is in the 'on' position without recording ?
Thank you
I have a issue in sony M4 it's click image in still photography...show half light and half dark ..any solution?? I clicked these images in day light ...no artificial light or flash used for that time
Which memory card did you use? I can record for only 10 minutes using the 4K 25 FPS 4.2.0 codec on the SanDisk Extreme Pro card (300MB/s read speed and 260MB/s write speed. included in the V90 class). It heats up and shuts down immediately.
Appreciated man ❤
So do you think its worth having the a7iv with over heating issues or maybe there will be an update
Thanks for these tests! I had a handful of cases with the a6500 back in the day where I got burned (pun intended?) by not opening the screen...looks like this will be a similar case here with the a7 IV, at least to be safe for longer recordings.
how about connecting a dummy to power bank? does that affect the heating?
Would a dummy battery be of any help keeping Heat down?
Most of these tests were done in winter and indoors. But what happens at 30 to 40 degrees Celsius?
I actually had my brand new a7iv overheat right after opening the box and navigating the menus for about 20 mins, very sad to see but just updated it and switched the threshold to high, it's warm to the touch but didn't shut down, unfortunately all of this was done in my room with ac on, and I need to use this outside in florida heat, I hope this helps.
Conclusion of the commentary space must be don’t charge the battery in the camera. It will heat up your camera up pre use and make it overheat doing even the lightest tasks. That’s useful info to👍🏽
Hello,
What about streaming mode please?
Which camera would you recommend for long streaming hours?
Hi - what memory cards are you using? Mine has way worse performance than yours and Sony support says it is because I need CF Express cards, not V60 cards.
Can you purchase a power adaptor and not use the batteries at all? Wonder if that helps
How do you set the camera to record over 30 min ?
This is exactly the video I was looking for! Need to record longer than 30 minutes on my A7iii
Lots of people looking for this info so glad it helped!
What scenarios are you in that’s making you record for longer than 30 minutes?
@@kykylouis5472 Recording for my channel
@@PrestonTalkZZZ ahh that makes sense. I see a lot of people talk about that but never give an example. I watch a lot of solo backpacking/travel videos and I’m sure there’s a ton of footage taken but the clips are short I can’t imagine someone needing more than 30 min but yours makes sense
@@kykylouis5472 So I have an ASMR channel (not sure you're into that) but the videos can get fairly long so I was having to keep everything under 30 minutes. Especially starting and not having a good take you'd have to start and stop again so I'd have a ton of clips and the flow is just off so that not being a factor anymore makes things a lot easier
how do we identify its an original sony battery? here in sri lanka vendors selling Sony A Grade batteries they saying its not original but closer to original.
I just “upgraded” to this but now I’m frustrated.. this never happened to me on the a73 … how is this an upgrade ? Mine overheated like 30 minutes.. at 4/k 30/p 8 bit .
Thanks for h the tips.
Great video Chris! It was fun to collaborate on this too!
this guy!!!
Does the Sony A74 overheat when in 10 bit 1080HD
Thank you for doing all this work! Does the camera save the files when it shuts down due to overheating? Or will you loose the entire recording? Thank you!
no replies...too bad, curious as well
@@RC-kd3ue I found the answer! it does save the files!
Thanks for this test! Screen open and we all can live 😅 👌🏻🔥
Do you think the camera would overhead if we're recording to the Atomos Ninja V?
nice!! have you try with dummy battery? that who'd be interesting because no battery inside changes everything.
What will be the performance if I want to use A7iV as a webcam for more than 6 hrs. will it last while charging ?
hello
thanks for the video
if anyone checked: use SSD instead of sd card ?
it could help and keep time?
Appreciate the tests! The only time my A7iv overheated so far was during a live stream (using the A7iv as a webcam). The camera was plugged into my computer via USB-C and I was on a Zoom call (streaming at 720p/30fps) when the overheating warning showed up around the 1hr mark and the cam shut down soon after. I'd be curious to see if you (or anyone else for that matter) experienced this as well because I've never had this issue with the A7iii (connected via HDMI to a capture card). Thanks!
I have the same setup for the same purpose and with door open, steadyshot off, high temp set to yes the camera shutdown after 6 hrs. I was doing 1080p/30fps.
@@reviewguy5140 Good to know, thanks! I have a feeling my overheating issue was due to the (non high speed) cable I was using. I'm now using the Sony cable that came with the camera. I'll do more tests. Also, I just realized there is a crop when streaming at 1080p/60. It looks like 1.5x - I haven't seen any info on this anywhere. Not a big deal for me personally, but I'm sure it'll affect some.
Was this shot with the 1.01 firmware update?
I shoot in 4k 60 for my DIY Car Audio channel most of the time but not for an hour lol! I occasionally shoot in 4k 30 But it's nice to know that if I ever need more then an hour in 4k 60 with XAVC S 4K i can just continue to leave the Screen open to keep the A7IV as cool as possible. I also use a 160GB Sony Tough CF Express Card The Type A for all my video. I only got a warning 1 time since I owned the A7IV which concerned me a bit but I did have the temp settings to High. My PC starts to choke with anything higher then 200M anyways lol!
Thank you so much for making this video. I have subscribed! 😁🙏
in the works
Whitch card to record didi you use?
I have recorded a couple concerts with recording over an hour using my A7iv and A7C (simultaneous from different angles) in 4K 25fps and neither camera overheated. Can’t remember if I had screens open, but that was probably the case going from your tests. My recordings were with no colour profile.
What about using an external battery?
Have you tried comparing it with different sd card brands for each camera? I am not entirely sure, but sd cards could probably contribute to the device's temperature.
Brands don't. Speeds do passively. When you record to the A7's full potential you'll most likely have a v90 card for example. That means you camera is more busy. If you record only with a v30 card you cannot use certain codecs and 4:2:2 10 bit --> cam is less busy.
But overall: a Kingston vs Sony vs whatever in same speeds don't give you any different outcome.
Love your videos bro. I think you should have had the cameras on tripods. The heat coming from the camera is then returned from the table it’s resting on. It’s not allowing the heat to dissipate through the base of the camera. Just a thought. Thanks again.
True. As soon as I lift it off a table, the warning light turns off.
Which camera this video was shot with?
I find if you connect to the A7IV using wifi (monitor+ app) it's guaranteed to overheat and have even bigger effect than the screen closed
Very good.
Thank you
I was shooting a live event on stage with the adapter powery (plugged in the power) and I got about an hour before it shut off, I was shooting 4K 30 60M 4:2:0, I need to test it more. The adapter battery was from amazon (third party)
This issue has been solved by upgrading the firmware?
Thanks for doing these tests! Moral of the story: keep your screen open!
Hi! I'm using the same config as you, 60fps = 1/125 // XAVC-S 4K / 200M 4:2:2 10-BIT and I can only record for 9 minutes... I'm really frustated... just change from slog3 to scinetone
Curious, what ambient temperatures have you A7iv owners filmed in so far? I just received 2 of these A7iv's to replace our A7iii's. We had been using the A7iii's with no issue (auto power off temp at high; ambient temps mid to high 90ºF's on average = 35º to 38º Celsius during the summer). Right now it's cold here in Oklahoma so I can't do outdoor test the A7iv's for those high ambient temps. I did heat up a room to 84ºF (29ºC), using XAVC S HD 4:2:2 10bit and got 90 minute recording on the A7iv without overheat. But still, that's indoor, with no direct sunlight. I stopped the recording since I knew the longest wedding ceremony I've ever filmed was just over an hour (Catholic; Full Mass; A7iii).
Just performed a test using XAVC S 4K 4:2:2 10bit. Heated the room up to 89ºF and it performed just as the manual said it would. Recorded for 30 minutes and then powered off.
I was filming a documentary today and it overheated after a couple of hours with lcd screen flipped out and heat setting to high. The issue is the camera generates a lot of heat just being on not even recording.
How were you able to get two A7IVs already? I Still have no idea when mine is going to arrive and I pre-ordered on the first day it went on sale.
ordered from two different places bang on the dot when i could
Overheated and shut down for my after 1.5 hours on the SI codec 600m 10 bit 4:2:2
Great video. I’m getting my a7iv in two days🎉 I hope I didn’t screw up when I bought two 256GB v60 cards ProGrade
So did you screw up?
I don’t believe you did as the v60 cards will enable u to record in almost all codecs apart from the intra frame codes
Did your camera overheat at all?
Hei! have anyone tried to shutdown the screen while recording *using only the viewfinder?
