I can’t find anything in the archives about this.

I’ve edited some GoPro files on WLMM. This all went as expected but the output at whatever resolution I choose looks like it’s been filmed on a kids toy. Choppy, blocky & laggy. It’s even worse once uploaded to Youtube.

The original GoPro files look great But after it’s been through the editing program the problems begin.

Is this a know problem or is it me ?

Thanks in advance, D.
