I am trying to merge and convert some mov files to an mp4 file. I found a solution at http://potentialinfo.blogspot.com/20...lips-fast.html but I lost the audio in the intermediate file.

This is what I got.

The video came out good but I lost the audio. Anyone have a suggestion of how to keep the audio?

first thing
having a Microsoft "blank space" in the folder name is not a good idea
" Iomega HDD "

remove it and re run ffmpeg

How do you know you lost the audio, you can't hear it?

If you have mplayer installed, could you post output with:

Or with other program that shows video file infos

Maybe be more explicit in your command. Something like:

-acodec being "audio codec" and -vcodec being "video codec"

Also, how are you determining that you lost the audio? just because your media player isn't playing it doesn't mean the stream isn't there. Get a proper analysis of your finished file with just this:

or use MediaInfo

The Iomega is an external USB harddrive. I wish I knew how to change it's name but I don't. Besides having a space in it's name it also has a \ after the Iomega which does not show up all the time.

I don't know what codecs to use to copy mov files to an mp4 file.

Thank you for the help.

Please use code tags to post code.

You should not confuse video formats with container formats. Both MOV and MP4 are containers. Both can contain MPEG-4 video. It is possible the video and maybe also audio do not need to be recoded at all, your MOV may be remuxed to MP4.

You are correct. I am not hearing audio when playing video using Video but I do hear audio when playing original mov video using Video. Sorry I missed the code tags.

You should run ffprobe on your MOV file to see what's in it, then you can decide whether you need to remux or recode.

http://winff.org/html_new/

I use the gui front end for this. Very easy to use.

This is the output from FFPROBE.

I did try Winff but I got a lot of error messages about possible bad parameters. I gave Winff 3 source files to merge. They should have all been the same format because they were all taken at the same time back to back without changing any camera setting. I did tell Winff to use the source directory for the output but I was never given an option to name the output file. I was hoping that Winff would merge the 3 files and since they should have all been the same format I was hoping it would have been fast. They were MOV files and I was trying to merge them as MP4 files. I do get confused with the container type and file format especially with MP4. Can anyone tell me the FFMPEG command to merge these three files as an MP4 file? I don't know which codecs to use either.
Thank you.

Your MOV has AVC video (this is MPEG-4 video), so do not convert the video. Considering all video codecs are lossy every time you re-code some quality is lost.
Audio you need to convert to AAC.
I recommend Avidemux, it is proven working video editor/transcoder for Linux. I'm a die hard CLI user, but when working with video I'd like to see it.

When I try using Avidemux it says that it can't find a demuxer. I am using Avidemux 2.6.14. I did find a similar post for MKV files which referenced multimedia/avidemux26 at. Does 2.6.14 include multimedia/avidemux26? Thank you

If I understand your end goal correctly, you're trying to concatenate some files together and produce a single mp4 file.

If this is the case, you should be able to do this:

1. Create an input.list file containing the names of each clip:

2. Do the concatenation:

3. Do the conversion. For example:

Some of those options may need tweaking, but generally that means:
* take full.mov
* convert to ffmpeg mp4
* with a bitrate of 13mbps (your source video is approximately 13mbps, so we're matching)
* with aac sound
* with keyframes every 66 frames

Thank you. The concat worked good and produced a 6 Gb file that plays video and sound. The libfaac codec was obsolete and I substituted -strict -2. The conversion is taking hours but appears to be working. How can I use Avidemux without the conversion when it can't find the demuxer?

I ended up using handbrake to convert the combined MOV file to a M4V file. The video played for 1 hour and it took 1 hour to convert from MOV file. The sound and video were also good and it converted the 6.8 Gb MOV file to 2.3 Gb. Thanks to everyone for the help.
