Please forgive the length of this inquiry. But it is complicated and has a lot of variables.
I have an hour long mixed format timeline both Red 3K footage and Black Magic ProRes 1080P footage that I want to make a DVD from and it takes forever and crashes half way through. I have tried doing it every way possible and the only way I was able to get even a partial export was using the "MPEG 2 DVD" export option in Premier CC. It goes fast at first telling me it will take about 2 hours but even though it starts quickly doing about 15 fps it slows down to less than 1 fps and finally just stops and crashes my Cuda Core enabled Macbook Pro Laptop.
I really don't know who to ask about this since there are so many different variables. I never had a problem like this on my MBP with PP6 on a 4K timeline exporting to DVD or Blue Ray or to H-264 or Even Prores. But I wasn't mixing formats either. But on this project the first 20-30 minutes of footage goes through fine in a couple of hours but something seems to be bogging down the system on longer projects. My work around was to break the project up into multiple exports and combining them on the DVD timeline but I can't do this on every project. I thought maybe it was a corrupted clip somewhere in the timeline but when I broke the timeline up into several parts I had no problems.
I did notice a dramatic variance in the time it took to export footage based on the sequence settings. A one minute timeline comprised Red 3K footage and ProRes 1080P footage Here are some sample export results:
From a Red raw 3K timeline 2880x1620 with 1080P Prores footage upscaled 150%)
to .m2v Mpeg 2 720x480 format 1:48 Minutes ***
to .mov Prores 422HQ 1080P 22 Minutes
to .mov H.264 1080P 22 Minutes
to .m2v Mpeg 2 1080P 22 Minutes
From a 1080P timeline Prores footage at 100% (Red footage downscaled to 67%)
to .m2v Mpeg 2 720x480 format 13 Minutes
to .mov Prores 422HQ 1080P 13 Minutes
to .mov H.264 1080P 14 Minutes
to .m2v Mpeg 2 1080P 14 Minutes
Since I am going to DVD, I chose the fastest option Red to m2v Mpeg 2 720x480 format which only took 1:48 per minute. Why? I have no idea. Maybe someone here knows the answer. But again these numbers are for a ONE MINUTE clip when I tried to convert the whole hour timeline to the 720x480.m2v DVD File the Red timeline froze my computer after several hours even though I had set sleep mode to “Never” and turned the display off manually and I had to convert it in multiple chunks. In 20-30 minute chunks it did go fast about 1:48 per minute like the test indicated. But I would like to be able to convert the whole hour and not to have to try to stitch the clips together in my DVD authoring program.
I don’t want to have to avoid using multiple formats on the same timeline or waste time transcoding everything to the same format.
Can anyone give me any suggestions as to why the computer is crashing or bogging down in long exports and what timeline settings I should be using?
I have plenty of room on my Scratch Disk and 8 Gig of RAM and according to my Activity Monitor during the export process have about 800 Meg of System Memory during export but the CPU Usage is 98% and in my Activity Monitor I see under “Process Name” ImporterRedServer flashing up at the top of the list about every second during export.
Why .720x480 mpeg DVD setting is so much faster than all the other export codecs?
And if there are any other settings I can use to get higher speed exports in HD? 14x1 seems a little slow especially since every time it crashes I have to start over.
