Hello again,
I've had this issue on previous version on Vegas (13 up to 15).
I render in 32-bit to avoid another issue I have with 8-bit (described at the end)
If I have the GPU enabled (in Preferences > Video) and try to render a 1920x1080 60p video, with 32-bit pixel format in the Project Preferences, it goes smoothly.
If I try to render into an uncommon or higher resolution (for example 2560x1080, or basically anything higher than 1920x1080), the render would start, and fail 10 seconds later with 'System is low on memory' error, like this:
My PC specs are as follows:
- i7 4790K
- 16GB RAM
- GTX 970
I'm not sure which memory the error is referring to (RAM? VRAM?)
Checking the Windows Task Manager (Win 10), my GPU VRAM is barely at 2GB of 4GB when this happen, and RAM pretty far from being saturated (8GB of 16GB)
This is the Project Setting I use:
(Upping the resolution from that causes the issue)
Rendering as AVC/AAC MP4. Using other formats, like WMV do not have issue, but as far I know they don't use GPU acceleration.
If you wonder why I use 32-bit:
I'm using footage coming from Nvidia Shadowplay (game footage), and rendering in 8-bit gives a washed out preview (and much dark final render). I've been searching about this since I've been using 13, and there are many threads on this, but not many solutions (something about 0-256 and 16-256 levels). Using 32-bit is the only thing that gives me the same colors as the original footage.
Shadowplay footage format is as follows:
The issue is not present if rendering in 8-bit, but my final render colors are not the same as the original footage (did not matter on the player, as this would happen on any device/software/site I tried to play the video on)
So either a way to solve the thing with 32-bit rendering, or a way to get my colors not changed in 8-bit. I've tried other softwares like Premiere and Resolve and this color issue did not happen there.
If more information are needed, just ask. And sorry if post came out pretty confusing.
Cheers
