If downloaded dadan videos do not play in QuickTime, it is because dadan uses the AVC3 codec, which QuickTime does not support.
Quick fixes #
- Use VLC Player
Open the video with VLC, which supports AVC3 playback natively.
- Convert to MP4/H.264
If you need QuickTime compatibility, convert the video to MP4 using the H.264 codec with a video converter tool.
These steps ensure your downloaded videos are playable across different media players.
