I have a problem. There are several computers with different processors. I create a complex project, more than 3 video tracks with effects. if you export video with 720-576 no problem. but if the resolution is increased to above 720p and then rendering is not possible. if you include rendering with CUDA then everything is OK. without CUDA, on a single processor error. but this error only on AMD processors. Intel i7 processors, the error is not present. tested on different computers, different operating systems, on different processors AMD, still if the error if the project is very complex. I do not think that the CPU AMD FX- 8320 can not cope with such a task.
I do not know English, I write through the translator, I think you'll understand.
