Video Recode Required

What kind of file? We allow opening of a bunch of different formats using FFmpeg as an intermediate decoder. Any file opened using that feature requires recode on output because it's being decoded by FFmpeg before it's even fed into VideoReDo. So all we have are decoded YUV frames.

My normal MPEG2 or H.264 TS/MKV files. Are you telling me that if all I want to do (my normal) is cut edit a video, that instead of doing a frame copy (except at the edit points), the complete file will be recoded? I most certainly do not want that. I haven't done any testing yet.

No it shouldn't do that with MPEG-2, H.264 or HEVC files. All others it will. If you're getting this with files that should fast frame copy then I'm not sure what the issue would be. I'd need to see the program info so I could see if there is anything in the file that would trigger a recode. Also what profile are you using? A default? Or a custom modified one?

I think I found it. I had another video up and noticed that it didn't flag it as needing recoding. So, I went back to the first video I tried and had a deep look at the info. Leave it to me to bring in a MPEG-2/422 video as the first file using the new program. I totally forgot that the ABC backhaul feed of the Oscars was 4:2:2. If it would have been H.264/422 then it wouldn't have loaded at all.

For historical reasons V5 supports MPEG-2/422. H264 and HEVC 422 is only supported in Pro.
