Premiere PRo rendering/playback issues.

[Andrew Johnstone] “I have not updated my OS software (on purpose!) on my edit machine. I am still running Mountain Lion. The system has run fine until this project. Unless the CUDA driver can become corrupted, how can this suddenly start happening”

Sorry for possibly misunderstanding you. I thought this was your first time using CS6 after moving from FCP 7. If you have used CS6 a lot before and this issue just started then it’s probably not the GPU issue.

[Andrew Johnstone] “Thanks

My Scratch disk (with a Gtech 3TB Thunderbolt connection)

write: 88.3 mb/s
Read: 68.8 mb/s

My Rushes archive drive (Lacie 12tb mirrored RAID with USB3)

Write: 34.1 MB/s
Read: 23.8 mb/3
“

Those are really slow speeds. I just tested my Gtech travel drive (7200pm, 1TB, Thunderbolt) and got 126MB/s write and 128MB/s read. Are the drives full?

[Andrew Johnstone]

David,

Sorry if I was not being clear.

I have just up-graded to the 2 new drives recently. Prior to this I was running PP CS6 cutting docs up to 15 mins long using a LACIE Mirrored RAID drive hooked up via USB3 and a older Gtech scratch disk connected by FIREWIRE.

Both these drives were fine and I never had an issue running PP. I will do some more plugin and uplugging of cables, but certainly a Thunderbolt/USB3 connection set up should work better than a UBS3/Firewire combo!

FYI, I have just recreated the first part of my edit in FCP7 from an XML file and it runs fine. Connected to the same thuderbolt Gtech scratch disk.

Bed time here now, but appreciate your help! Will check the threa din the morning.

Thanks

Andy

Sorry I was having a late night, ‘glass of wine, thick moment.

The TB drive speeds are of course faster than the USB3 drive speeds. For some reason I was looking for a number that said ‘speed’ not ‘amount of data’ – ie. under 10 secs for the 100m is quicker than than over 10 secs.

I will look at the USB3 write speed, but the problem may just be that the drive is not cabled directly into the mac but via a USB hub (too many peripherals!)

Will check that out when I fire up a little later. Either way it looks like I need to find a faster solution. But again, I have worked seamlessly for years using Firewire cutting HD timelines, so TB & USB3 really should be able to cut it!

OK I have re done the plumbing in the back of my system and both my archive RAID and my scratch disk are wired directly into the Mac with my external screen on a Thunderbolt daisy chain loop from the back of the Raid disk.

My external RAID had been on a USB3 connection via a hub, which is most likely why it was so slow.

Anyway, net result is that I am still getting video playback issues with PP (jumping images, bad image blocks etc), so my plumbing solution has not worked.

The net result is that I have decided to rebuild my Edit in FCP7 from the XML file. So far I have no issues with playback, but I am only half way through the ingest…well not even. I hope this retrograde step works as I have to deliver this film next week.

Will need to do a thorough investigation into what the issue with PP is, but my hope that I had found a fast stable, reliable alternative to FCP7 seems to be fading.

Pretty naffed off. I have now spent 3 days trying to fix this issue.

OK slow going, but I am now grading my project without a hitch in FCP7. No sign of a video glitch etc.

I confess to feeling miffed that FCP7 ever went away. I have never tried FCPX as no professional editors that I know use it, but if PP is going to play dirty on large projects (again I have never had these issues before with PP), then I need to find a new best friend.
