Hello,
Does anyone here managed to get the KeyframeSelection process succeed in extracting frames from a whole 4K mp4? What would be the proper settings ? To mention here that I am not interested in a regular step extraction, but regarding the keyframes variation.
In my case, whatever the parameters are, I only get one or two frames extracted for let's say a 60 sec drone footage (DJI Mavic Pro).
The only workaround I found was to scale down my footage from its genuine resolution (ie toward 1920*1080 px)... then apply the default process setting, which works pretty fine.
After all I end up with an homogeneous path that I managed to properly align and reconstruct
But it's not enough (Mavic' sensor abilities to photogrammetry are quite poor), I'd like to be able to run the whole 3d process from the original resolution so I'll have to manually pass the calculated frame list to ffmpeg in order to extract them from the 4K footage... Not very straigthforward... any better idea ?
thanks in advance,
Alban
