Audio codec

[charles.schneider]

I am working with VideoReDo Version 2.5.3.500. I have several video clips downloaded from tv and various web sites on my hard drive. They are all named variations of VTS_01_1.VOB. When I try to join them into one file, I get the following message:

Current Join project uses an audio codec unknown and sample rate 4800. Video being added has an audo codec AC3 and sample rate:4800. Audio parameters must be the same when joining.

If I try to Combine the same clips the VideoReDo freezes and I have to Ctrl/Alt Delet out of it.

My question is are these clips "unjoinable" or what can I do prior to joining to set up all the clips in the same format. I would like to end up with an mpg file.

Thanks

You should check that they are the same parameters. Load the files into VideoReDo and press Ctrl+L

Your files also may contain multiple video and audio stream. You may need to select a different stream in order to combine them. Tools>Select Stream

Here are the Joiner limitations from the Help file:
Joiner Restrictions: There are a few restrictions on nature of the files that can be joined. You will be warned if you attempt to join files that don't meet these criteria.

Files must be of the same type. You can only join MPEG-2 files with other MPEG-2 files and MPEG-1 files with other MPEG-1 files.
Audio sample rates must be identical. You cannot join files that have different audio characteristics. The audio bit rates may be different between files.
Video picture size must be the same. MPEG files can be encoded with a variety of picture sizes (i.e. 720x480, 480x480, 640x480, ... ). The joiner will insure that only files of the same size can be joined. The video bit rates may be different between files.
