I've been recording Prores 422 with an I2/X5s. I always set the exposure to M (manual) as I don't like the stepwise aperture adjustments of the auto modes.
On multiple occasions, I'm seeing a sudden (stepwise) change in exposure. Not sure what's causing this, as I can confirm that I'm always in Manual mode; and, right camera dial is untouched. It seems to happen in a pan, altho' I can't confirm that.
Any comment from DJI?

Raven, to locate where the problem exists, we need the original footage for evaluation.
Would you please upload an original video directly from SD card to Dropbox? please do not edit it at all, then post the link here, thank you!

Appreciate for that, thanks.Besides, it will be better if you can export both videos from SD card and SSD card when it happens, if subtitle is on the video from SD card, it may be more helpful for our engineers to locate the problem.

I believe I may have found the cause of my uncommanded aperture change. I was using the OEM 15mm lens, at the time. With the rubber protector covering the aperture ring, I hadn't noticed that the aperture ring had shifted to one of the aperture positions other than 'A'. It's entirely possible that it was in betweeen click stops. I'll investigate this possibility when I have the free time to explore it.
