Errors and Red Flashes with MXF files

Question

Hi all and Adobe, this is the third time i have posted hear about this and it is now getting very serious as the problem is affecting my income as I run a small one man video production business.
When I encode video that has any MXF file in the timeline, and most of my projects do as I generally am editing two to three camera shoots with one of the cameras being a Canon XF300.
I get many errors, and multiple red flashes in the encoded video.
I run all of my Adobe CC applications on a 2013 iMac 27" 3.5 Intel Core i7 32 gig Ram Nvidia GeForce GTX 780m 4096MB
There is no bottleneck regarding disk drive as I am using a dedicated GRaid 8TB Thunderbolt drive.
I first ran into this problem within a week of upgrading to the latest Premiere Pro CC 8.1 Caravan. I then noticed it when using Media Encoder when encoding both Premiere and After Effects projects Smith MXF files involved.
I at first thought the problem may have been corrupted cache file so deleted them all and re conformed. I even uninstalled Premiere cleaned out all relevant directories then reinstalled.
No matter what I tried the problem will not go away.
I went online and noticed in many forums people complaining about the same problem and coincidently most seem to have the problem appear since the last upgrade.
I then rang support and after a very long wait spoke to a man who advised I need to select Cuda in the GPU settings and delete all previews, so I did this while on the phone to him then started encoding a project and to my delight no errors.
I was so excited I jumped on here to tell another person who had a similar problem the solution.
But then within a day the errors were back and with vengeance, at the end of one of my last encodes yesterday I had an error log window that filled an iMac 27" screen not good.
I then rang support again and as with the previous call a long wait ensured.
After explaining my problem and indicating the discussion I had with the previous support person he indicated that Adobe was aware of this problem and they were trying to fix it.
He suggested a work around and that was to encode only using the Mercury software not any GPU settings.
So off I went and encoded the same project and guess what happened, more errors many errors.
Also please note to be thorough I tried encoding a project from 2013 that has worked perfectly before on previous versions of Premiere but as soon as it is loaded into this version the errors appear.
I also wish to bring to attention the abysmal support mechanism Adobe has established.
There seems to be no way to fast track serious problems.
I and many people like me need this problem solved as we rely on Adobe for our living.
If this continues for much longer I will have to reconsider my investment in the Adobe CC product.
Any assistance would be greatly appreciated.

Answer 1

Over the last couple of hours I tried an experiment using the same project which contains a two camera edits containing video from Canon XF300 and XHA1 cameras.
The experiment was to encode out form the project on three separate Macs.
As I have explained in the first post my main Machine the 2013 iMac gives errors on any setting including GPU selections.
I then tried it on an older iMac a 2010 model 2.93 GHz Intel Core i7 which has an ATI Radeon HD 5750 1024 MB GPU and the same problem occurs.
Next came an old Mac Book Pro 2011 that does not have GPU support. The project rendered without any errors but took about so long compared to the 2013 iMac which is to be expected.
So the problem seems to be related to the relationship between Premiere and the GPU's.
I hope this helps the Adobe engineers sort this out.
