Encoding a video while keeping keyframes as the source?

[kolamorx]

Is there a tool that can encode a video while keeping keyframes as the source?

[Sharc]

Not as I know. Why would you want to do this? The encoder will do the optimum choice for you.

With the x264 encoder you could use a qp file to force I,P and B frames for the frames you specify.

Out of curiosity: Why would you want to do that?

It's complicated...

It's complicated...

1) index source file with ffindex.exe -k
2) convert keyframes from text file to proper text file which x264 understands.
