Why?

While it makes sense to want an I-frame instead of a P-frame, because
there are things you can do with an I-frame that you cannot with a
P-frame, the symmetric does not apply: an I-frame is functionally a
P-frame, just one that only has new blocks.

So, before you ask how to do it, you need to explain, possibly to
yourself, why you think you need to do it.

Odds are you will realize your exact need is somewhat different.

[FFmpeg-user] Modify i frame placement in videos

2021-07-14 Thread Jaeho Bang 
Hello,

I was wondering if there is a way in ffmpeg to convert I frames to P frames.

For example, let's say I have a video of 1000 frames and currently I frames
occur every 200 frames (so 0,200,400,600,800 would be I frames).
I would like to convert the I frame at 200 to a P frame, so as a result we
have 4 I frames.

Thanks in advance.
