Streaks when playing MP4 video

I produced a 4k video using Video Enhance AI in .mp4 format. The file plays correctly using VLC on my Windows PC but on the Vero 4k, I get streaks in most of the image (though the top left of the image looks okay). Any ideas for playing this properly? It looks like this:

Can you upload the MediaInfo for this?

Is this what you need?

I think you would probably have better luck if you encoded it with h.264 or h.265.

This is a strange encode.

What encoding options are you using in your application?

Unfortunately the application I’m using (Video Enhance AI) doesn’t have any encoding options. This is how they encode for the mp4 option. The others are tiff or png images which I will probably have to re-encode into a video using another application.

There are other people on their forum that have complained about this.

I don’t think we accelerate this in hardware at all; so it sounds like software decoding (ffmpeg) is failing, which could imply a problem with the clip.

Can you post some debug logs so we can see if the video is being played back with acceleration?

Thanks

Sam

Just Re-encode with something like handbrake

Here is the video log:

Log snippets don’t really help, and that’s not even a debug log.

I don’t know what I’m doing when it comes to logging. I’m just going to re-encode in Handbrake and call it a day.
