Compression for burning
Hey all,
I am confused about what’s going on with burning my video project to DVD. Because DVD Architect was telling me that video would need to be compressed, I rendered the project as MPEG-2 anad that solved the problem. But now it says that my audio needs to be compressed. Well, I converted all the audio to WAVE format (a format that works with DVD Architect), and it still says that it requires compression…I’m not sure why, because everything should now be a supported format…MPEG-2 and WAVE. Could anyone let me know why this is not working? I’d rather not compress anything if I can help it, as I am submitting the project to a film festival and want all the quality I can get. Thanks much,
God bless,
Tyler. -

Are you sure you rendered your WAVE file in a compatible format? There are lots of ways to render a non-compliant WAVE file. DVD PCM audio uses a 48K sample rate rather that the 44.1K of CD’s. If you rendered your WAVE file at 44.1K that’s why DVD Architect needs to re-encode it.

Thanks for the reply.
I figured it out finally. I rendered the audio and video from the movie separately. Audio I rendered as AC-3 (5.1 surround) and video I rendered MPEG-2 and put them together in Architect. It may have been a roundabout way, but it burned with no compression. Is there any loss of quality from the standard video you capture from the camera and MPEG-2? I feel like MPEG-2 is a bit of a hinderance on video quality, maybe it’s just me…Having an old Sony DCR-HC30 680,000p video camera can’t help I suppose..Thanks again,
Bless,

Yes, but it’s unavoidable. DVD’s only support MPEG-2 so that’s what you have to work with. You should not be seeing much of a difference in quality at all.
Glad you figure the audio piece out. Both AC3 and PCM are valid for DVD audio.
