All of a sudden separate audio & video files

[amigasteve]

Haven't used FFMPEGX for a while, since then Leopard came out and the 10.5.1 update.

Previously working presets now give two output files:
movie.mpg.ff.mov.audio.mp4
movie.mpg.ff.mov.video.mp4.

Not a clue as to why nor how to fix it. Has 10.5 changed the behavior and caused this issue or am I somehow inadvertantly doing something wrong?

Check the logfile for more detailed information on what might be going on. Click on the "i" in the Progress pane.

Out of curiosity, do those individual files play properly?

the video file plays fine but quicktime give an unknown file format error when the audio files play.

If I try and mux the file (tools tab) I also get an unknown file format tab. Strange.

The failure to recognize the audio is an important clue. It could very well be that you need to install/update an audio codec.

Again, the Progress logfile will likely be instructive in narrowing down the suspects. Also, when you drop the source file into the summary window, what does ffmpegx say are its characteristics?

strangely enough it only happens (so far) when I try either of the H.264 encoding options. If I use the MP4 preset it works fine. Here's the log from an H.264 encode:

I have the same issue when the video file gets above 2G in size.
Then the audio tool says something like "The file is not a valid ISO file" and refuses to mux them together.
For now I am attempting to use Quicktime pro to import the audio and then passthrough export to mp4 and see if that works.

Not sure if the 2G limit is what it really is, but files that are 1.2G are fine, files that are 2.4G fail.

add this to the top field in the advanced options box to get rid of the out of sync audio:

-async 1

and if that does not work try

-async 0

The latter was first recommended to me and did not work, the former worked like a charm. Don't know what it does (anybody?) but id did fix my out of sync audio prob.
