iMovie output to anything, no sound

[rikyo]

Hi,

I need to create AVI XviD from a video produced by iMovie. I have exported from iMovie a couple of different ways (MP4 and .mov) and the same thing happens. The picture is perfect, just no sound. As an example I'll include the details from the MP4:

filename: test2.mp4
Source format (identified in the drop zone): From MP4
Video: mpeg4, yuv420p, 640x480
Audio: aac, 44100 Hz, stereo

Target: To AVI XviD
Video: mencoder svid, 640x480, 940 kbps, 29.97fps, no crop
Audio: mp3, 4800 Hz, 128 kbps

To note, in the audio tab, thse are the settings:
Codec: .MP3 (encode audio is ticked)
Audio parameters
Audio bitrate: 128
Sampling 48000 Hz (changing it to 44100 does not change things)
Channels: Stereo
Mode: CBR
Audio track: 0
Invert mapping OFF (changing it to ON does not change things)
Audio Gain +0
Add audio.. (blank)

When I encode, this is the start of the output (asterisks mine):

If I change audio track to 1, it gives the error about being unable to find (2). Change it to 2, it says it can't find (3), and so on.

iMovie seems to only allow me to save audio as aac. But ffmpegX converts a completely differently-sourced MP4 with aac audio fine (MP4, video h264, yuv420p, 320x240, aac, 48000 Hz, stereo)

This makes me think something weird is going on with iMovie's output. I can't think of what else to try. Suggestions?

The picture is perfect, just no sound.

MOV: selected audio stream (1) does not exists

Suggestions?

This seems very similar to the issue mentioned in the MP4 to AVI - no sound, no subs thread. The inverted stream order is messing with the "-aid 1" mencoder option. I've come to consider this an ffmpegX bug.
You could go command line without the "-aid 1" option,
or reverse the streams manually with MP4Box (1) or QuickTime Pro (2).

This makes me think something weird is going on with iMovie's output.

You can't avoid the inverted stream order with Apple's apps, as this seems to be build into QuickTime export functionality.

Thanks very much, Case. I had skimmed that thread (and all the others I could find) and not fully understood the final post it until I wrote all of the above. Reading that thread carefully, it indeed seems to be the problem you describe here. I would consider it a bug, too. Thank you for confirming that it was to do with the iMovie export.

I am needing to convert files for a very specific limited-time purpose and should only need a week or two's worth of use (for now) so I have just tried the DivX 7 Converter, which gives a 15 day free trial. The output of that program seems to play very happily on the particular fussy piece of equipment I'm doing this all for!

I am a little hesitant to learn to use the command line for ffmpegX right now in case I miss something else important (and I don't have a lot of time for this project). I'll try the command line options if I need to come back to it. Overall, it seems a very neat program, so I'll very likely be back! Thanks again.
