Vegas 21, build 108.
During video playback, these artifacts appear in the preview window:
The video itself was recorded on the phone using the AZ Screen Recorder application. I tried changing the bitrate and video quality, but to no avail. I even tried recording the video through other apps, but the result is the same.
However, the artifacts do not appear in the video player, I only see artifacts in the preview window in vegas.
What can I do to solve this problem?
