What playback software are you using? The 4K77 crew recommend MPV and Kodi, and recommend against VLC. Stuttering playback is a common complaint, since it’s such a large file.
Gotcha! Thanks for pointing this out, I figured there had to be something else going on. I did the entire procedure correctly, and my computer’s built for 4K playback, so this makes sense that it’s a player issue rather than an actual print/file issue.
Thanks for responding!
