Hi Colorjet3, I read somewhere that if you convert the MP4 video files first , then it seems to play OK. [image: image.png]

So I used VLC convert to "video for youtube HD" and the preview works fine!

The original resolution: [image: image.png]

and the converted file resolution: [image: image.png]

I have no idea why this works, but maybe you do.

Thanks for a great program!

Hello @lozzo52. This is something common in the video editing world. OpenShot, being opensource and dependent on volunteers for development, doesn't have the ability sometimes to deal with irregularities with video/audio combination files with frame rates, bit rates, etc. So, you will need to run it through a converter which will normalize the file.

Some more advanced editors will recognize this irregularity and either converted for you or prompt you to convert it.

Glad you are moving forward with your project.
