Q: MTS playing in slow motion but sound is normal speed

Hi,
A friend took some mts video for me and gave me the SD card - I'm able to see it in several programs but it's always playing in slow motion though the sound is normal. How can I get it to play normal speed? Or covert it to normal speed? Thanks!

A: If you videos are from cameras or camcorders, it must be syncing well. So the problem may lies in the media player you choose. So at first check your computer specs, and make sure that it runs fast for work with the media player on your mac.

Then for playing mts files on mac, what is the best Mac MTS/M2TS player? You can try mplayer osx extended, or VLC to play it back. Quicktime cannot handle transport streams very well.

VLC media player is said to support AVCHD footage on Mac, and you can choose to play the files. However, there is also slow motion problem when playing .mts .m2ts files with VLC. The audio plays in normal speed, while the video time is double as what it should be. In other words, the sound is OK but the image lags behind. This might happen to computers with low configuration - CPU, video card. 

Many users do not have a powerful enough Apple computer with Intel Core i7, good graphic processors, and they may expect Apple QuickTime Player to natively support AVCHD videos, just like the WMP in Windows 7. So for smoothly playing AVCHD on Mac, they may need to convert AVCHD to QuickTime MOV on Mac.
