Twitter broke something with their video and audio muxer that messed the moov atoms, now every video that was downloaded from june 23rd (at least I noticed it was since then) have audio and video that don't sync, and freezing frames
So far the only solutions are to run the videos through a compressor like uncut or sony vegas 17, you convert mp4 to mp4 as funny as it sounds it also works but it increases file size a little bit, If you use K-Lite Codec Pack thier built-in player MPC-HC can play the videos fixed so no need to do anything there, cuz their filters can sync them again. Another solution is to use FFmpeg, either you have it installed or from here "https://ffmpeg-online.vercel.app/?inputOptions=-i&output=output.mp4&outputOptions=", this also will increase the file size a little bit.
The most painful one is to re-download the videos again using yt-dlp, doing this won't increase the file size.
So until either the extensions work again or Twitter puts it shit together, these are what we can do.
