Note:
The 1440p file seems a bit corrupted around 1:25:37 to 1:25:39. So far from my test, VLC will not be able to continue playing the video properly if the playback hit the region, so if it happen in VLC, close and reopen the file and jump forward to skip the 1:25:37 to 1:25:39 region (Playback > Jump to Specific Time), maybe directly to 1:25:40 without going through 1:25:37 to 1:25:39. SMPlayer with MPV backend however can play through this corrupted area, at least the Linux version.
