Guys, I use a paid video editing program called Camtasia 9.1.2. And I always rendered my videos from MKV to MP4. A time passed, out of nowhere when I started rendering to MP4 as I always did, in a few seconds in the video, the image gives some strange bugs and I do not know what that is. I already rendered it in WMV and everything worked fine in the image and everything was right but the quality over MP4 is inferior. There I want to render in MP4 but it always gives it here: Can anyone help me solve this?
