Any advice when editing 1pass stats file, P-frame to I-frame..

[Hogan77]

I'm about to edit the 1pass stats file so that the ordered chapters jumps will land on an I-frame. Can I just move I-frames to where I want them, or is there certain things that will break when I make the new encode?

Example, I want an I-frame on frame 62755, in the stats file it's an P-frame. And the closest I-frame is on frame 62743, like this:

P-frames depend on the previous I-frame, so at best you'd have to add another I-frame, not move it around.

[Hogan77]

Ok, so let's say I just add 4 I-frames. It will break the "Keyframe Interval" but maybe the second pass don't mind that?

Thanks, for the help, :)

[Dark Shikari]

You can do that fine, I think, but the main issue is that it'll somewhat mislead x264 with regards to the other information.

[Hogan77]

I'll try adding a few I-frames and see how it goes. :)

Once again, topic about inserting I-frames at beginning of chapter... Is there any correct solution of this problem?
