I've been working with Sony Vegas for quite a while and it has been working without a glitch, however, now I'm scratching my head as my projects have come to a screeching halt since I no longer am able to render my videos.
The format I am using is MainConcept AVC/AAC (*.mp4). Please note that the following problem only applies to this format. If I choose wmv instead, it works, but unfortunately it lacks the quality that I'm looking for (and the rendering times are horrendous).
When I try to choose to render anything using MainConcept AVC/AAC (1080p/720p/480p etc) the following error is displayed just before the rendering starts: "An error occurred while creating the media file filename.mp4. The reason for the error could not be determined."
I have tried to find a solution on the internet have done the following to try and solve my problem:
Updated to the latest version (which I believe is build 595)
Checked the HD space (1.4 TB)
Checked that the name was not already taken.
The only thing that have "worked" so far was to go into the Custom Settings on the MainConcept AVC/AAC format and change from "Automatic" to "Render using CPU only" in the Encode mode roll down window. However, this defeats the purpose of having a good graphics card, like I do. Things render at least twice as slow, and black spots in the videos (after they have rendered) can be seen as the CPU is seemingly struggling to handle the render.
I have, however, just recently upgraded from a GTX 580 card to a GTX 680. Could this be the culprit? I would have to see such a powerful GFX card being unusable in a video editing program!
CPU: QuadCore Intel Core i7-960, 3333 MHz (25 x 133)
Motherboard: Asus Sabertooth X58
RAM: 12 GB
Graphics card: NVIDIA GeForce GTX 680 (2048 MB)
Thanks in advance for any assistance.
