Hi, I have problems with Webm and mp4, especially with the webm. Here are some examples:

Webm at 48 frames:

Webm with 10 frames:

in both videos it looks like it jumps I'm using version 1.3.0 of Peek

now the videos are in another color and when I upload the webm to another hosting they look different

Same Webm to 48 frames in another hosting:

Same webm to 10 frames in another hosting:

On my Linux Mint Mate 18.3 Sylvia 64Bit looks like this:

As you can see in Xplayer it looks bad but in VLC and MPV it shows the color correctly

I hope you can help me solve this problem. Thanks in advance
