DJI Pocket 2: Juggling ISO and FPS in low light

- In an attempt to avoid overexposure by manual settings, it was surprising (to me) that 30 vs 60 fps gave shots of different exposure levels, even at the same ISO. Shooting at different frame rates reveals that in auto mode the camera consistently gets the same (over)exposure by adjusting the ISO. In place of makeshift manual exposure, it should take but a minimal adjustment to the camera's algorithm so it consistently gets optimal exposure in auto mode.
Good video and explanation, thank you for taking the time to test this and making a detailed video about it, very insightful and helpful!
Wow thanks, I'm glad you find it interesting 😊
Thank you so much for posting this video. I've been struggling over the past few weeks to understand shooting at night and in low light with my pocket 2, and your video cleared everything up for me. I can't thank you enough! In your most recent videos walking around at night - were you shooting on auto or manual with changes to your fps/iso? I just love the quality of your night footage.
Wow thanks, I'm glad you find the video useful. In my recent videos I shot on auto at 60 fps - some overexposure can't be helped at times, but the payoff is that the camera can adjust the ISO as necessary in darker scenes (in manual mode, well, you'd have to do this manually😅).
thanks so much! great help for a newbie like me❤
You're welcome, and thanks for watching 😇
8:12 Your friends at DJI heard you, loud and clear!
Did they? 😀👍
excellent test video. BTW, how did you get the continuous reading of the shutter speed, ISO etc? thanks
Wow thanks 😇 The video files are embedded with subtitle tracks (format tx3g) with the real time exposure information. You can turn on the subtitle when viewing on VLC for example. To extract them you can use ffmpeg.
@@thestion77 thank you 🙂

very informativ....but sad at the same time that DJI Auto-Iso and shutter speed doesnt work probably. So if I shoot videos at night, it will never be correctly exposed because the light changes all the time. Even if I limit the ISO that would mean that some scene will be too dark.
You are right that there is no catch-all. With auto exposure some scenes risk getting too bright, on the other hand if we limit the ISO manually, some scenes risk getting too dark. But even if the raw footage is not ideal, you may be able to salvage it in post-processing. In my other video (Jalan Alor, Bukit Bintang) the street is nice and bright at one end, but gets progressively darker as we walk through. As I had the ISO capped at 800, the unedited raw footage is awful in the second half, too dark! But by boosting the "shadows" (Lumetri color correction) gradually up to +50%, I think it does a decent job of compensating the exposure, while still looking natural (noise notwithstanding).
@@thestion77 thanks for the answer. But another question is, if the resolution of the video is lowered, from 4k to full HD, will the Pocket 2 capture more light? (because of pixel binning or does Pocket 2 dont use pixel binning technologie?)
From my experience shooting with this camera, full HD and 4K look the same to me color-wise. At any rate, I think the hardware already does the pixel binning natively from 64 MP to 16 MP anyway (4K resolution is only 8.3 MP), so going from 4K to full HD is just a codec/software job. The only time the pixel binning actually matters would be in the high rest photo mode where you can snap 64 MP images.
Areas and subjects within his frame are lit drastically different. It would be a challenge for a camera to know which he wants exposed properly: the dimly-illuminated inflatable play areas and street pedestrians? or the brightly-lit vendor stalls? What small camera - or any camera, for that matter - could properly expose both at the same moment?

how do you see the iso values?
They are embedded as a subtitle track in the raw video files
you created interesting .would you like more view?s, see ya!~✨
Thank you, and I'd love more views 😇
Some one please buy it for me 😢
