Have you tried this with the original BMPCC? Again my experience is that the micro jitter rolling shutter makes post stabilization difficult. I haven't tried this in Resolve but can you build a rolling shutter camera profile? At the very least that would be a must. I've tried this is other software and while one can account for general rolling shutter skew, micro jitter is a problem. Please do let me know how you've handled it.
I suspect the BMPCC4K has significantly less rolling shutter but there's been nothing specifically indicated about that. Just enough EIS to get rid of micro jitter would even make post stabilization much easier.
I run a small test in Resolve and After Effects to compare. The footage is from 5D raw.
I guess the biggest issue is not the rolling shuter jitter, but motion blur, which, after stabilization is even more apparent. Like the two adjacent frames below, after stabilization:
- blur-vs-noblur.jpg (497.72 KiB) Viewed 111122 times
Unfortunately, electronic stabilization won't be able, without a very strong processing power to remove the motion blur from the frames. Edit: oh, forgot Camera Shake Deblur in AE, will give it a try, one moment... ok.. it's the last video in the list.
I think the best option would be to use IS lens plus post stabilization using perspective or warp depending on the movement and subject. This would eliminate the ugly motion-blur-jitter, and PC would then be able to make it look really pretty. I didn't have any IS lens at hand to give it a try tho.
Here is warp stabilization in AE, with and without rolling shutter compensation. Which looks terrible, just because it's... well stabilized. So the motion blur is more visible.
