Q: Every time I try to Render it says - An error occurred while creating the media file - the reason could not be determined

Answer: When Movie Studio or Vegas Pro stops processing in the middle of rendering a new video, and gives you an error message like this: "An error occurred while creating the media file - the reason could not be determined", there are a couple of reasons why this has happened.

Here is my check list

1. Re-boot your Computer !

If you have been doing a lot of editing over many hours, then it is often a good idea to SAVE As and then do a RE-BOOT of your computer before you attempt to Render a Video. This will clean out your memory and give you a clean slate.

2. Try a Clean Re-Boot of your Computer

Try a clean boot to start Windows with a minimal set of startup programs. Here is a Windows article on how to perform a clean boot: https://support.microsoft.com/en-us/kb/929135

3. Reset the software back to default values

Sometimes mysterious alien artefacts can build up inside the hidden program cache and cause bizarre behaviour. Do the following to clean out the Cache and Reset the program. Please note that this will reset the desktop display for the program.

Hold down the CTRL and SHIFT keys on your keyboard, and at the same time double click the program icon on your desktop to boot the program.

Select Delete Cache and Yes 

The cache is now cleaned.

4. Remove unused Media

Remove unused media to help free up resources. You can purge unused media from your Project Media Window in Vegas and Movie Studio. To do this, go to the Project Media tab and you will see a button that looks like a lightning bolt. Clicking on that will remove any unused media from your project and help to free up system resources. Movie Studio 13 Platinum has this feature in Tools -> Clean Project Media.

5. Try working on your project in pieces

Try working on your project in pieces. For example if your timeline is 30 minutes long, save three ten minute sections into three project files using File -> Save As. Edit each section separately, render, and re-import into a new master project to stitch them together into a final audio and video stream.

6. Try replacing the media in your project

If it always hangs at the same frame or place, try deleting the files at that point in your timeline and then replace those with newly transcoded or recaptured clips.

7. Try to avoid any customisation with your rendering templates

If you are using custom settings for rendering, try rendering without any customization applied. If that works, then you can guess that your custom settings are not compatible with your rendering format.

8. File locations

If you're working in an environment where files are scattered across multiple drives, try placing your media on your local disk drive.

9. Virus Protection program is too aggressive

Try adding the .exe file for the program to the exception list for any anti-virus software you are running on the system.

10. Do you have Apple Quicktime installed ?

You must have the latest version of Apple Quicktime installed if working with .mp4 style formats. There really is no choice with this, please have Quicktime installed at all times for Vegas to work correctly.

11. OLDER VERSIONS OF MOVIE STUDIO HAD PROBLEMS - Which version of Vegas Pro or Movie Studio are you using ?

Older versions of Vegas Movie Studio were susceptible to a Low Memory Error in particular situations. Specifically, Vegas can have a problem accessing enough RAM (memory) for users who had Movie Studio HD Platinum 32bit version installed on Windows 64bit Operating System.

Vegas Movie Studio HD Platinum 11 and all older versions of Movie Studio are only 32bit programs, which means they can only use a Maximum of 4GBs of RAM, even on a 64bit Computer that may a much higher amount of RAM installed. Not only is there a 4GB limit, 64bit users could also experience a glitch which limited there available access to RAM, to just a mere 2GBs. Movie Studio Platinum 12 and 13 now come with a 64bit and 32bit version of the program.

In a project with 720p or 1080p HD Video, this results in Vegas just freezing up. Fortunately this problem for 64bit users was fixed during one of the free Build Updates for Vegas Movie Studio HD Platinum 11 - Build 283.

12. Check for Free Updates and New Build Versions of your Program

Always make sure you are using the latest Build Version of the program you are using. Bugs and updates are continually been fixed and added to the programs. Many times a simple program update may fix your problem.

13. Did you add a tonne of Video Fx ?

Sometimes if you add too many Video FX into a chain, it can cause an immediate crash.

First step to diagnose this problem is to temporarily TURN OFF all the Video Fx and then try to render again. If it works, then you know one of the Video Fx is causing the problem. Try next to turn ON one Video Fx at a time and do more test renders until you can narrow down the problem child.

14. Are you using the New Blue Fx Titler Pro ?

Older versions of the Titler Pro were very buggy in Vegas Pro and could cause Vegas Pro to freeze or crash. Check updates for the Titler Pro and then do another render.

15. Are you using GPU Acceleration ?

Try turning OFF GPU Acceleartion in the Vegas Pro or Movie Studio Platinum Preferences, which are found in the Video tab.
Go to Options - Preferences - Video

16. How much RAM do you have installed ?

Version 11 and older versions of Vegas Movie Studio can only access a maximum of 4GBs of Memory (RAM). Even though this is the case, please make sure that you DO actually have 4GBs of RAM installed. I have seen time and time again some people on Laptops only having 2GBs of RAM installed. This is just way too low for any Video Editing program to work with properly. Once you throw a couple of HD Video files into Vegas, it's going to completely freak out.

RAM is cheap, so make sure you have the full 4GBs installled.

17. What type of Video are you trying to Render/Create ?

If you are attempting to Render a 1080p Video from your project with too HIGH a bit rate (on 32bit versions of Vegas Movie Studio) it will crash older and slower computers with low RAM capacity and/or low powered CPUs.

A solution to get around this problem is obviously to lower the Bit Rate you are Rendering to. Anything under 10MBps should be more than enough to create a nice looking video. Trying to render to 20, 30, 40MBps is just silly.

Another solution for people on low powered machines is to switch to 720p settings instead.

18. What type of CPU do you have ?

To have a great experience with Vegas Movie Studio when editing and creating full 1080p HD Video projects, you must have a modern 4x Core CPU (Central Processing Unit) as the "Brain" of your computer. Older Duo Core CPUs just can't handle processing HD Video files, and can be a reason for Rendering to crash and produce errors.

19. Which format are you rendering to ?

Avoid Windows Media Video .wmv if you don't have much RAM and very low CPU power, when working with 1080p Video. Windows Media Media will suck up ALL your CPU resources while rendering - it's just how the codec behaves.

Sony AVC .mp4 or Mainconcept AVC .mp4 are the best formats to render to, on older/slower computers.

If rendering any AVC templates, make sure to use CPU only encoding.

20. What is the condition of your Hard Drive ?

HD Video files are very large, so you need plenty of Hard Disc space for them to be written to. If your Hard Drive is almost full and never been de-fragmented, it can slow up rendering times and in worse case scenarios create a crash.

21. If none of the above solutions work, you need to pull out the big guns and perform a clean uninstall and reinstall of all your sony programs
