I hope this question is in the right part of the forum.
What is the best software for natively editing H.264 .mp4s?
I work on a daily TV show. We stream live in with Adobe Media Encoder, so I get .flv files of the show on the fly. We also upload segments to youtube for viral purposes. Until recently I'd been using Moyea FLV Editor to carve up the segments, out of the full FLV file. You don't get frame accurate editing but it's there is NO encoding time either.
We want to podcast... so we got our hands on the new Black Magic h.264 encoder. It works great and we're getting beautiful highres MP4s at the speed of light. However, [this is where I need your help] I haven't found a good way to segment them without going to an intermediate codec. If I'm going to an intermediate... Why bother with the Black Magic Encoder. I'd like to be able to cut them up on B frames the way Moyea does with the FLVs.
I managed to do a quick cut and save in MPEGstreamclip. Plays back great locally but after YouTube compression I get audio synch issues. Which I imagine is a result of cutting on A frames.
