Encoding a video while keeping keyframes as the source?

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

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?

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

Out of interest... What video format is your source?

Those file name extensions refer to container formats not video (stream) formats...
