So, more like a time lapse?
I think Motion has that built in
Xeoma definitely does - not in the freeware version

Subject: [Motion-user] Timelapse video with inter-frame compression?
Hi.
My question is from me researching how to create a webcam with minimal data
needs (to save mobile data costs).
It basically is, does motion support inter-frame compression on timelapse
videos?
Background:
The cam will need to send a few pics per hour to a server. Pics will have
minimal visual difference (observe a river's waterlevel).
So the idea is to save data by using inter-frame video compression.
The basic setup would be: on- camera (raspi), append every new pic. as a
new frame to an eg. daily video.
Send only the diff of the video file to the server, which will present the
regularly updated file to users, extracts the last frame if only a pic. is
needed, etc.
I am happy about any kind of input to my idea, namely towards any roadblocks
I am not aware of yet.
I first found motionEyeOS, which has it's own way to do timelapse videos,
that seems not suitable for my idea.
Not sure if this question should be asked even deeper down the stack, in an
ffmpeg related forum. Just tell me if I am off-topic here.
Thanks,
toro

Could you send the new movie file and a log with -d 9?
