Cyberlink PowerDirector 9 - Importing mov files in the timeline removes audio?

I'm trying to trim a few mov files using PowerDirector. When I drag them into the timeline, no audio track shows; when I click play no sound is heard. However the f开发者_如何转开发iles do have sound, it gets removed only when added to the timeline for editing.

I need these files trimmed and then transformed into .flv

Why do you think this happens? Or, can you recommend me another piece of software?

Thank you, Cris

PowerDirector probably lacks the correct audio codec used for the audio inside the MOV file (obviously check you are running the latest version first).

You could play the file back in VLC and check the codec information (under Tools->Codec Information I think). Quicktime probably has a similar screen for showing codec information.

Once you have determined the codec, you basically have two options:

1. Find another movie maker type program that supports MOV files, the audio codec, and the video codec, and also has other features you need (eg outputs FLV).
2. Extract the audio track from the MOV file and reencode it to mp3 or another audio format PowerDirector can import. There are several tools that can probably do this (depending on the codec), but FFmpeg is probably the most likely to work.

The second option is probably the easiest, there is documentation and examples on FFmpeg use all over the net, for extracting audio (it can also convert it in the same step).

Jus try unlinking the video so that video and audio are separate. Delete the corresponding audio of your video. Insert the desired audio track to your video and it must work
