Sony vegas an error occurred while creating the media file

Dear goods,

If you are using secondary internal or external drives normally, one test you may want to try is to try saving a project or file to your Desktop rather than to your secondary drives. Does that work? If so, and if the files that you are normally working with are stored on a drive that is not drive C:, then you may want to check your permissions within Windows as they are applied to any other drives that you are working with.

More information about this can be found here.

How to Grant Permissions in Vista and Windows 7 / 8 / 8.1 / 10

1.) Locate the file or folder on which you want to take ownership in windows explorer.
2.) Right click on file or folder and select “Properties” from Context Menu.
3.) Click on Edit button in Properties window.
4.) Click ok to confirm UAC elevation request.
5.) Select user/group from permission windows or click add to add other user or group.
6:) Now under Permission section check the rights which you want to grant i.e check “Full
Control” under the “Allow” column to assign full access rights control permissions to
Administrators group.
7.) Click Ok for changes to take effect and click ok final ok to exit from Properties window.

Forums › VEGAS Pro › Vegas Pro 13.0 – “An error occurred while creating the media file […]. The reason for the error could not be determined.”

• When i try to render my project this is the error message shown:
  “An error occurred while creating the media file […]. The reason for the error could not be determined.”

  Every solution found on the internet suggested rendering CPU-Only which i already did.
  Some suggested that it could be the lack of space on the HDD.
  system drive: 18GB Free
  drive where project gets rendered to: 2TB Free

  By now i have not found a solution working for me. Hope someone can help.

• Hi,
  another reason can be if very bad render settings are specified. For a really wild example, mpeg with 575*357 resolution.
  So what are your project/render settings?

• Hi,

  thank you for your answer.
  My project/render settings are 1920×1080/60fps/28Mbps

  Best regards

• Hi,
  full HD 60p @28Mbps what? MXF? AVC? (Sony or Mainconcept?)

  Did you tweak any render setting? If yes, what setting of which template?
  If not, which template do you try to render to?
  Do you have write peission in the folder where you need to place the rendered file?

  Best regards

• Hi,

  Full HD 60fps @28Mbps MainConcept AVC/AAC
  I tweaked the template Internet HD 1080p changing frame rate to 60 and the bit rate to 28Mbps.
  I do have write permission in the folder im rendering to.

  Best regards

• It should work.
  If you did not tweak any other settings, it should work.
  I did the same here just right now.
  Took the builtin 1080p template, changed bitrate (both avg and max) to 28 Mbps.
  I changed then the framerate, first tried 59,940 (double NTSC) then tried 60,000 too.
  Both worked.
  Does the file exist you are trying to render to?
  If yes, is it possible, that this file is open and locked (maybe by Vegas itself, for example if you try to overwrite a file via render, but that file is also part of the project – it’s on the timeline or somewhere in the media bin)?

  Best regards

• It works fine when i use the standard Internet 1080p template but as soon as i change something the error occurs.
  I render to a completely new file everytime not overwriting any existing file.

  Best regards

• I’m out of ideas, sorry.
  I have V13 build 545, which is already a Magix build. If you have build 453 which is the latest Sony build (I think), that may have a bug…
  You may try Vegas14 trial, just to see if it works as you expect it to work?

  Best regards

• I tried using Vegas 14 and it worked the first time. Now its the same as in Vegas 13, as soon as i tweak some render settings the error occurs.
  I took a look at everything but the time of occurence seems to be totally random. Still, thank you for helping.

  Best regards

• You’re welcome.
  All this suggest me, that the prolem is specific to your computer, and it’s not really a Vegas roblem.
  I’d try to reinstall the OS and Vegas (on a separate new HDD), just to try if it’s still present.
  If the reinstall does not cure, then I don’t know…
  But you’ll still have your original HDD with the original installations.

  Best regards
