Since the last update to Premiere Pro (June 2015 9.0.0 build 247) the program monitor goes black every now and then.
It happens once the projects starts to be a bit complicated (one clip above the other with one effect or more).
Paused resolution is 1/2 and playback is 1/4, I also tried to change the paused res to 1/4 also, but it didn't help.
Every time I relaunch Premiere Pro it works again for a short time and the problem comes back again.
If I render the video (press enter), then it works for the rendered part.
It didn't happen on the previous version I used (CC 7.0.0).
I use iMac 27" mid 2011 with Mac OS X Yosemite 10.10.3
Specs:
- 2.7 GHz Intel Core i5
- 20 GB 1333 MHz DDR3 (2x2GB and 2x8GB)
- AMD Radeon HD 6770M 512MB
The project is on my "Book Thunderbolt Duo" - thunderbolt 4tb external hard drive.
I use mp4 H.264 full hd 60 and 50fps footage (one video 50, and the other is 60).
The render is on the only option I have which is "Mercury Playback Engine (Software Only)".
I really hope you can help me fix this, thank you!
