Audio Codec for Broadcast

Hey guys,

I have to deliver a music video and am stuck on the audio codec.

I know PCM is considered to be loseless, while AAC is lossy,
but when testing the files via DVD on TV, I (and all others) liked the AAC codec better.

Does that make any sense?? Is there a reason not to use the AAC codec?

Thanks,

Who accepts broadcast quality music videos on a DVD?
If I were you, I would contact MTV Euro or whoever you are going to submit the video to and ask for their broadcast guidelines. If it's not in a format they want it will go straight to the trash and never get played.

AAC does not fall within the DVD specifications AFAIK. PCM, MP2, or AC3 are spec right with MP2 being the least supported of the 3 right?

Its a smaller satellite tv station, so calling MTV is not very helpful.

And yes its a DVD, but a Data DVD (with the highest resolution quick time file possible), not a playable one.

The point is that any broadcaster has a set of technical standards for submissions available for the asking. The best way to find out whatr formats are accepted is to call up the station you're submitting to and ask 'em.

Yes indeed, the uncompressed 48K PCM would be the best choice.
In addition with QT-pro (about $30. USD) , allows one to replace the audio track, so re-rendering the video element is not necessary.
