trimming flv files

[Craig@GroovyGecko]

Hello,

We are having intermittent issues with lipsyncing to video after trimming flv files (either under h.264 or vp6). Since Adobe don't seem to have an official tool for doing this we are using 3rd party software such as flvknife and avidemux.

I am guessing this is some sort of keyframing issue but I'm not sure.

Anyone had similar issues? Can you recommend a more solid solution?

Cheers

Craig
