I purchased the "Illuminate" series of Light Leaks from Rocketstock which are advertised to be compatible with all NLEs. Each "leak" is a 4k mp4 file. When I try to import into Vegas I get an error

"File cannot be opened - make sure that the file exists and you have access to the folder"

I also cannot play the file directly in Windows Media Player or in Quicktime but can play with my VLC player. Any suggestions?

can you post file details....

I download 13 Free 4K Light Leaks from Rocketstock and I can open its in Vegas Pro 13.0.435
Art, check filenames in the root to your files. May be root is too long or contains unicode symbols.

When I right click on the file and look at the properties most of the parameters show nothing. I was wondering if was a permissions issue but everything looks the same when I compare it to another mp4 that I can open successfully.

I purchased the "Illuminate" series of Light Leaks from Rocketstock which are advertised to be compatible with all NLEs.

Quite frankly, I’d contact Rocketstock and ask them to stand by their word and fix the problem.

Art, try using VLC to convert the file(s).

Click Media/Convert
Add files (drag and drop) - maybe try with just one first.
Click convert
Click on the tools icon alongside the profile.
I tend to use the default values but you may wish to change them to suit
Supply a destination file name (the originals won't be overwritten)
Click start

Now try opening it in Vegas. I can't promise it will work with your clips but I have had the same problem as you in the past and this worked for me (with 1080p footage, not 4K).

Good luck.

Thanks Ian - I saw a similar suggestion on a Youtube video and I followed the steps you outlined. I get up to the point of naming the destination file but it doesn't seem to recognize the file type as no matter what I enter for the name the resulting file has a .ps extension even though I have .mp4 selected under the tools icon. I did find another conversion tool (Bigasoft Total Video Converter) that seems to convert the file successfully. The free version only gives you half the clip though.

Yes I think that was where I got it from originally!

.ps seems to be a filetype used by VLC to simply play a file. I wonder why that's happening :-/
