Audio track not recognised in DVDA 4.5, but in 4

veganer wrote on 5/15/2008, 1:16 PM
I used DVDA 4 successfully to create DVDs from my TV recordings.

DVDA 4.5, however, does not recognise the audio track, which is in 48kHz stereo PCM format. I can load the video into Vegas 8 and render the audio as a separate stream, but I'd rather DVDA 4.5 would handle the audio correctly.

Has anyone had similar experiences?

Thanks.

Are you sure it's PCM? Download

GSpot

run it, and drop the video onto its interface. It will tell you for sure.

The reason I ask is that I have various TV capture software (including ATI) that claims to be recording in one format (e.g., PCM) but actually is recording in MP3. It is possible that you have some format that DVDA is having a hard time recognizing.

Also, in DVDA, double-click on your video file, and then on the right side of the DVDA interface, click on the Track Media tab. Do you see any file name under the "audio" section? If not, click on that item and choose "replace." Then, point to the video file (I assume the audio is embedded in the video file). See if that makes DVDA "happy."

Yes, I am sure it's PCM. Before I feed the video to DVDA I cut it using VideoReDo. When exporting I select the settings so that DVDA 4 had always been happy with and did not feel the need to recompress either video or audio. - Onyl DVDA 4.5 does not recognise the audio stream, even if I point it to the mpeg under Audio (which is empty), as you described.

As I said, version 4 is happy and does not complain. Version 4.5 just does not seem to recognise the audio. (Vegas 8.5 does, though.)

Extra data can be added to a wav file - at any rate if DVDA 4.5 doesn't like it, you might try re-writing it (not re-encoding or altering the content in any way) to see if it passes thru whatever filtering DVDA 4.5 has in place. If Vegas handles it, just re-write (render) the wav audio to file without any changes, which should just take a few minutes, then try adding it separately to DVDA 4.5. If that doesn't work maybe your install of DVDA is broken? If it does, find out what's different with the Vegas re-write.

If I render the audio from Vegas as 48kHz PCM, DVDA 4.5 accepts it with no problems.

BUT: Why do I have to do this for DVDA 4.5 when DVDA 4.0 reads the MPEG including audio without any problem?

You're right, you shouldn't have to, but even if it doesn't seem like much, now you know that something with the original isn't kosher as far as DVDA 4.5 is concerned, that your installed copy of DVDA will handle wav audio, & you have a way to create DVDs *for now*.

At this point you might want to contact tech support, & maybe they'll have you send a small clip they can analyze - I know all sorts of software for checking out video, but haven't ever come across anything (or looked for it really) that gives you the same sort of data for an audio file - maybe someone else will chime in?

Otherwise if you wanted to you could try importing a recorded clip into DVDA without using VideoReDo - if it worked that would mean something changed when VideoReDo wrote the file, & maybe you can compensate in the VideoReDo settings?
