I don’t use .avi either, magicyuv codecs work for QuickTime .movs too. You should be able to select magic yuva 444 under QuickTime codecs. That should allow you to render an uncompressed QuickTime file with an alpha channel.

I have the same problem still… Here’s my workaround:
For 1080p projects and below, I use DNxHD220+Alpha, that seems to work for me at the moment. For everything bigger, or for odd sizes I will render using MagicYUVA (https://www.magicyuv.com/) it’s not a 10bit codec, but I think it works pretty good, and I think it’s pretty fast.

Obviously if my render doesn’t require an alpha channel then I’ll use DNxHR/HD or even UncompressedYUV 10bit and then convert to ProRes with FFMPEG.

Side note, my testing shows that you can not use FFMPEG on windows to convert any file with an alpha channel to a prores4444 quicktime file with an alpha channel, it works on mac though.

I don’t think it’s necessarily an El Capitan issue because I get the same issue when a file saved from Yosemite too.

My current bandaid is to open the .aep file, save an .aepx (XML) file, then run script on it that converts the filepath code to windows. That seems to do the trick for now.

I’ve figured out that I can save a project file as an XML, alter the file paths from Mac to Windows, and it will open perfectly fine in Windows. I’m working on a script to do this for me, but what a dumb work-around, there’s got to be a better way to not run into this issue.

I was tricked by the Mac OS (again)! So I guess you can’t always update Cuda from inside system preferences. I was on a much older version than the current Cuda driver available on Nvidia’s website. Once I updated from there I got everything back.

I have “GPU (Open CL)” available, but not “GPU (Cuda)”. There are no more newer drivers, I’m also on the latest version of Mac OSX.

So as far as Mac goes, is that also the case? Because I have a Mac with a Quadro 4000 that was working fine, but when we updated to CC 2015, the Cuda option in Premiere went away and the Quadro 4000 for mac was also dropped from the recommended list for CC2015 (it is still listed for the older versions of Adobe though).

January 14, 2016 at 5:32 pm in reply to: P2 Clips Not Playing Back

Actually I’ve found I can’t play video (only audio works) if it has a “DV Movie (HD NTSC 16:9, 48 kHz locked)” or other form of “DV Movie” codec. This is true for Mac and Windows versions of CatDV Pro 11.1.2

However these files play fine in every other program on said computers.

Is there some other codec pack or something I need to install?

Perfect! Exactly what I was looking for! Thank you!

Thanks Tero, were you exporting on a Mac or a Windows 7 or Windows 10 computer?
