I can't get mp4 videos to work.

I am on a windows 10 PC, using quicktime, but the file is an mp4. I am using the most recent version of Datavyu as I downloaded it last night.

I can't get the file I want to load when I go to "add" data. I have tried more than one mp4 file. It says "Could not open data source: Could not initialize class

The file plays on my quick time viewer on my computer.

Do I need to convert them to .mov or is there a work around?

Thank you!

We had the same problem on Windows 7. We addressed this by converting the files to .m4v format (high quality .mp4) using Handbrake (link:[]).

There is a specific version of Quicktime that needs to be used on Windows 10. Please download and use Quicktime 7.7.6 because anything later than that as it won't install on Windows 10.

Download link here:
