Batch encoding AC3s at DVinfo.net

Emre Safak · September 7th, 2005, 01:52 PM

I use Procoder to convert files from DV to MPEG2. In the process, the audio channel is demultiplexed into a WAV file. Since Procoder can not create AC3 files, what is the easiest way of converting a folder of WAV files to AC3? I would hate to do it manually in Vegas (my editing application).

the wav files created by procoder typically have a limited bitrate, in order to fit on a dvd... depending on your application, they would probably not be suitable for use as an ac3 encoding source.

Not at all; they are 16-bit PCM files. I should have indicated that I was working in stereo, not surround.

16-bit pcm at what bitrate, tho? and how does that bitrate compare to exporting an uncompressed wav file directly out of vegas?

16 bit at 48khz--unmodified sound from DV.

my bad, now i see what you are saying... i wonder if anyone has written a vegas script that batch-converts wav files to ac3? even if you had to buy it, the cost should be less than getting another ac3 encoder... sounds like a good question for the vegas forum.

ReelDVD from Sonic ($250) will batch encode PCM files to AC3. There are other solutions (i.e. by Minetonka Audio) but as far as I know, more expensive.

Best regards.

Thanks, for weighing in. I ended up using Belight.

Vegas->Tools->Scripting->Batch Render

Good Luck!
