Do a test from a new project with a clip that creates issue? OK/KO?
If it works :
Workaround: with an old project => Try to manually delete everything that is a cache
Hi Jean-Claude,
- I installed a fresh copy of 14.1.1.
- Created a brand new project.
- Selected one .MXF clip from my library.
- Without even dropping the clip into the project library or adding it to the timeline, I got the error "Your GPU Memory is full".
Clip is 90 seconds from a Sony PXW-X70, 100 Mbps 3840x2160 29.97 fps XAVC MPEG4.
So I figured I would try and determine if the fact that this clip is in a compressed format had anything to do with it. I changed the default view from icons to List in order to avoid taxing the system with displaying instant frames from the clips when one hovers over it with the mouse. Then I added one clip to my project media, and generated optimized media for it. The result: no more crashes! I have been playing with the clip, adding color nodes, etc... and so far, not a single GPU Memory Full error.
So, it seemed that the system was choking on the decompression of my UHD MPEG4 media, not really graphic effects processing.
Could it be a bug with the processing of the Sony MXF format I am using?
Having nothing to lose and trying to prove this point, I started to add more clips from the same project but this time without first generating optimized media. If video compression was the problem, DVR 14 should instantly complain about GPU memory issues. Surprise! Still no crash! I've pasted color nodes from one clip to another, tried playback/stop/fast forward and many combinations that I know, used to crash the program without being able to make the GPU Memory error reappear while editing the timeline!
It is as if the initial sequence I used when starting this project to gradually add clips without Live Preview was key to not consume GPU memory to its limit. Strange. There might be some memory management issues when preparing to process compressed video files.
I hope someone from the development team reads this and understands what is going on. It is puzzling to me.
