When rendering a video as an mp4 file in VEGAS Pro 14, I receive the following error message: “An error occurred while creating the media file. The file could not be opened. Make sure the file exists and that you have access to the file/folder.”
This error does not appear when rendering as an mxf file. I did not encounter this problem when I used Sony VEGAS Pro 13. Is anyone familiar with this problem and have suggestions on how I can fix it? Thank you for your help!
Which render template are you using? If Quicktime is somehow involved, make sure there are no spaces in the output file name or the output file's subdirectory name. This was a problem once upon a time, may not be any more.
Maybe try something simple like changing the render file name and /or rendering into another folder? Sounds like a basic file conflict.
Other possibility: I think it is a result of custom resolution using SonyAVC/MVC.
For custom resolution, you need to use Mainconcept AVC/MVC.
Hi Set, I have Vegas 14 and got the same error using custom resolution SonyAVC/MVC. I tried Mainconcept AVC/MVC using Customer Resolution and no error. It's rendering as I write. Two questions: 1) Why can't you use customer resolution using SonyAVC/MVC - what's the problem? and 2) Why is Mainconcept AVC/MVC limited to 30 fps? Sony has up to 60 fps. Thank you!
1) Why can't you use customer resolution using SonyAVC/MVC - what's the problem?
What resolution do you want? The maximum resolution for that codec is 1920 x 1080.
2) Why is Mainconcept AVC/MVC limited to 30 fps?
It's not. The maximum frame rate is 172fps. You have to manually over-type it in the box.

Some background, I shot in 3840x2160x30fps and was rending in 1920x1080 just fine but then wanted to render in 4k. I chose the Sony SonyAVC/MVC 1920x1080 then clicked on Custom Resolution and input 3840x2160. I did this based on a couple of YouTube videos I saw on rendering in 4k. It didn't work. I kept getting the error. I then saw the posting above by Set and tried Mainconcept AVC/MVC Customer Resolution and it worked fine.
Regarding 1) above, I didn't know the the maximum resolution for the Sony codec is 1920x1080.
Regarding 2) above, I also didn't know that the maximum rate is 172 fps. I was looking at the drop down menu only.
Thanks for the link above....very helpful!
Question, should "Allow source to adjust frame rate" be checked?
Since I'm a rugged individualist, I always enter it or select the frame rate manually. They could remove the check box and it wouldn't bother me at all.
Question, should "Allow source to adjust frame rate" be checked?
Like john_dennis, I never check that box.
It's now unchecked for me too.
I have Vegas 14 and everything was working fine. I then took a trip Windows 10 updated and now when I render a video, which I had already rendered previously, it freezes at 18%. I have a Windows 10 Asus Gamer Laptop, with Intel Core i7-6700HQ CPU @ 2.60 Ghz and I'm using a NVIDIA GeForce GTX 960M GPU. I'm trying to render using Mainconcept AVC/AAC 3840x2160x30fps. I have the GPI toggle as ON. These settings are what I used previously. Does anybody know what could be happening now? Why is it freezing? Also, I was going to turn the GPU accelerator OFF but am of the understanding that it is supposed to help speed up rendering. Any assistance would be appreciated!
