I Can't Seem To Do Some Simple Things Here...

[cyber0ne]

It's probably that I'm just not seeing something in the interface or doing something wrong, but I'm having trouble with a couple simple conversions.

I have an xvid .avi file with no audio tracks, two .aac files, and one .srt file. (Yes, I demuxed these from an .mkv file.) What I'd like to do is as follows:

1) Convert the .aac files to .mp3 files.
2) Mux one of them with the .avi to have an .avi with a single english audio track.
3) Mux the other one with the .avi and burn the subs into the .avi to have another .avi with a single non-english audio track and hard-burned subs.

The first thing I tried to do is just drop the first .aac into ffmpegX, select "audio file to mp3" in the target format, and encode. But it takes a _long_ time and results in a much larger file than expected, and the playback is slowed down dramatically.

If I drop the .avi into ffmpegX then I'm not seeing how to add an external audio source (the .aac file for now, since I haven't been able to convert them to .mp3 yet). And If I just try the "mux" tab under the "Tools" tab and select the .avi and the first .aac, nothing is output.

Am I just going about this all wrong? Maybe I'm just too used to the VirtualDub interface and this is confusing me? Any help would be much appreciated, thank you.

Try this: http://conglomco.org/aac/aacConverter.hqx

This will convert the aac file to aiff. Then you can copy/paste the audio into the video file using QT Player Pro and save as a reference movie.

Drop the reference movie into ffmpegX and add in the srt file. Convert that to avi using mencoder.

You will have to use the older mencoder binary from the .9s version if you want to alter the size or placement of the subtitles; otherwise, the latest mencoder binary is fine for this task.

Pay attention to the video and audio parameters so that unexpected changes aren't implemented.

Let us know how it goes.

A useful utility. Thank you for the link.

using QT Player Pro

The $30 one? I'm afraid I can't budget that just yet, so if that's my only option then I'm going to have to hold off on this for at least a month.

No big deal, I bought a copy of Parallels with this Mac so I can still use VirtualDub and the various other utilities to which I am accustomed if I have to. I'm just slowly working on moving all my stuff to Mac and only keep that copy of Windows for emergencies.

I'm just concerned that I'm not using ffmpegX correctly. The interface in those tabs seems a bit unintuitive to me, but other people don't seem to have a problem so I must just not be getting something. My current test case is just one possible scenario. Sometimes I'll want to convert .wav to .mp3 and mux that into the .avi, etc. Sometimes I'll have a single-audio .avi where I just need to change the encoding on the video and/or audio, etc.

I'll continue to try things out as more test cases present themselves. If I have more questions, I'll be sure and check back here
