    I have a DSC-S40 Sony Camera that takes MPEG-1 Muxed Movies (details in picture). I am running OS 10.4.7 and QT 7.1.2. and ffmpegX 0.0.9w (0.0.9w_r5). I want to be able to edit these movies in iMovie 05, iDVD 05 and Final Cut Express. These programs will not read the MPEG-1 Muxed file. Apple says I need a third party app. I have been successful at using the demux tool in ffmpegX but then i have an audio and separate video file that i have to sync. This will get tedious. I have tried to convert the MPEG-1 Muxed video to DV and MPEG4 in ffmpegX. ffmpegX reports that the conversion was successful, but when i try to open the file i get an "Error opening movie" message from QT. When the video is converted in ffmpegX it seems to happen to quickly. When i get info on the file, its size is zero. I have no idea what is wrong. can anybody help?

    After the (failed) conversion is done, press the button in the ffmpegX Progress window, to get the log. Copy that to a text file and attach to a post here, so we can have a look. The log should hold information on what it failed on, then hopefully we can suggest a why and a fix.

    THANK YOU!

    The following is from an attempt to convert to DV:

    It seems your camera produces MPEG files that have the order of video and audio reversed. The audio stream is listed before the video stream; and ffmpegX expects it the other way around. There is a checkbox in the audio tab to "invert mapping", which tells ffmpegX how to deal with that. Tick that checkbox and encode again.

    That did it. Thank you.

    Sense you did so well with the last one. :-) How can i find out what the ffmpeg options do, like "High Quality?"
