Project Manager

[Tom Daigon]

If your media is h.264 then PrP cannot truncate the clips to match what was used in your sequence due to the long GOP form of compression used on the clips.

If they were Prores or DNxHD the PM would do exactly as you desired since they dont use a long GOP style of compression.

I don’t understand. I was under the impression that the Canon MXF format is not H.264 but MPEG2. It is long GOP though. Does your answer still make sense if it’s MPEG2? I would assume you would say yes, as the answer would be that whether the footage is H.264 or MPEG2 (or 4) it would not work because it’s Long GOP.

Apparently Adobe has said that we should go request a feature to have this done properly. If what you are saying is that it’s the Long GOP format, it doesn’t seem to be something they could implement in trimming.

Pity that in order to actually trim the footage we have to go back to re-encoding the footage into ProRes or DNxHD! I guess we could argue that it’s the old pay me now or pay me later. Faster editing up front but longer transcoding in the back end.

So from a practical standpoint: Do I edit all the long GOP footage, then use encoder to export it to DNxHD and then send it to Project Manager? Or is there a different workflow to approach this?

Since you did not mention what the codec was, I was just presenting an example of a long GOP format that would be problematic.It sounds like that applys to MPEG2 since you keep getting the error message. I have worked with h.264 but not MPEG 2 as a media source.

I believe your only option at this point, with the completed project is to archive the whole thing. And depending on size that could require a single or double Blu ray disk. Or a hard drive. Or an LTO-5 tape system…

The problem I have doesn’t even allow for me to use project manager at all. Whether I want to trim or move the entire project. Are you saying that I could transcode my .mxf files in the sequence as something like prores or DNxHD? And then possibly use the project manager? That could be something I’d be OK with as it would still be less time transcoding than when we were using an offline editing system.

[Tom Daigon]

You should be able to copy the project, just not create trimmed clips.

Wosrt case scenario, just copy all the necessary files yourself to what ever storage device you choose.

I can surely do this manually through the finder, but its a hell of a lot more work. I guess I was just wondering if anyone else is having the same issues? Has anyone solved their issues? Or if they can get it to work, what codec are they using? Could the difficulty just be in the codec?

[Michel Gallone]

I can confirm that with Premiere Pro CC as of July 4th 2013, the issue with Long Gop mpeg and H.264 when trimming a project in Project Manager has not been fixed yet.

That really mean that we should follow the good old habit of transcoding to ProRes or DNxHD if we ever think that we might want to save a trimmed version of the final project.
Hopefully the adobe team will eventually get it solved.
