Multiple audio tracks

I have recorded some movies (with a Siemens M740) with 2 audio tracks.

I would like to obtain the 3 streams. My first experience was to edit two times the movie, one with each stream selected. Bad luck, in that case, the 2 video streams have not the same length (neither the audio BTW).
Is there a way to have the 3 streams in one editing step ?

Currently, VideoReDo will only save 1 video and 1 audio in the output stream.

So what could be the trickor the options for having the same length of video/audio after the two edit sequences ? (one for each audio track)

I've always thought there should be some way to make the following trick work... somehow...

Load your video; edit out the commercials; save the .Vprj file
Now, any time you load the .vprj file, VRD will reload your source file with the same exact cut points.

I'm sure Phd can suggest a way to use this procedure to let you save several times, each with a different audio track.
A little cumbersome , but it should get the job done.

I'm just not sure when you can change which audio track is selected.
You may have to edit the .vprj file to do it
(which is trivial, since it's a simple text file)

If you load the VPrj file into notepad, it will list the PIDs in the file.

Load the original file into VideoReDo, make note of the PIDs you want and place them in the file and save as a new VPrj file.

For example:
<VideoStreamPID>224
<AudioStreamPID>192

Thanks for the trick. The issue is that even with an accurate selection of the scene, changing the audio stream changes the results of VRD algorithms. The number of dropped video frame is not the same. The consequence is that the resulting DVD is not synchronized. This is why it is important to have the multi-stream function available.

BTW, surprinsingly enough, even on exactly the same project, the number of dropped frames is not constant...

Do you mean running the same project over and over. After saving out each file, vrd reports a different dropped frames number each time.

Are you using version 501.

As Robbi said, do use the latest version.

You had me scratching my head there, for a minute.
I was going to suggest you run the source through QuickStream fix first, then try the editing with the .vprj as mentioned above.
That way you'd have a clean source....

However
, QSF only supports one audio stream, so that won't fix your problem at all.
So close to a work-around.
Sorry, I'm out of ideas.

This is a problem that need to be fixed with VRD, check you have the latest version or report what version are you using.

I'm interested also in editing TS with multiple audio tracks up to 3. I think I read somewhere that VRD can handle the problem files 2 ways, either droping video frames to sync with audio or padding the audio to sync with video (not sure, have check again). I guess it should work if no video frames are removed and the audio gets fixed instead.

Is it exactly the same project with exactly the same edits or something has changed?

With using the same project with no other changes made. On saving the the number of dropped frames should be the same.

Anole had this same or very similar problem with each file save. Dan or Pat found the sollution and fixed it. Or was it a localised problem that was a self fix, i'm sure Anole will comment further here.

I don't really think this applies to the current question.

Can you create a small test file (30-50MB) and VPrj file that demonstrates this anomaly and upload it to us?

Also, clear the log file and try processing the VPrj file multiple times and include the log file.

To clear or view the log file and save it to a new location for submission, click on the menu: Help>Display VideoReDo.log

Confirm that repeat saves of the same segment has the problem before uploading.
ftp://upload:upload@videoredo.net/

Create a folder with a unique name and place the file in it.

Send an email to Support@VideoReDo.com and let us know when it has been successfully uploaded.

Also include a reference to this topic number 3467
