Render Process

This is a question I asked in DAR and they recommended I ask in this forum.

I am using VMS 6.0 & DAR 3.0 on a dual core AMD desktop with 3GB ram and several HD's over 250GB each, so I have plenty of storage and recources for my work.

My question is workflow; i am using VMS to capture my home VHS and 8mm tapes to vegas, saving as AVI files. I am capturing using the 29.970 NTSC settings in the capture settings box.

When I'm done capturing, I bring the video into VMS and apply any splits (generally at 10 minute segments and mark them and title the episode marks ( Part 01, part 02, etc). I then render the project and save it to it's own file, as an AVI file. Most files are 90 to 120 minutes.

When the rendering is finished, I bring it into DAR and select Make DVD. I usually have to optimize the disc, then select burn. The first thing DAR does is render the video. This seems like a duplicate step to me, a very time consuming one.

Can someone explain the reason for the double rendering or a way around this if it's not necessary. I've read a bit about different types (avi, mpg, etc) but i don't claim to comprehend the benefits and reasons for them. I'm looking for as simple and straight forward workflow to capture and burn my family video's onto DVD's with chapter markings of my choosing in as little time as possible, given the confines of the equipment and tasks.

I did read this in another post:

........ audio should be rendered to AC-3 (or PCM). DVDA will NOT re-encode if you do this.)

I cannot seem to find a way, in VMS, to render video and audio separately within VMS.

thanks

If you choose the mpeg2 DVD export via Vegas, it will only export the v ideo. You then need to export the audio in AC3. If DAR supports that and it puts them back together afterwards, I would suggest you do it that way.

Otherwise, I would suggest you export out of Vegas with a lossless codec rather than DV AVI which is lossy. Then DAR can do its re-encoding in a lossy codec, mpeg2, only once.

Thank you for taking the time to reply. I'm too new at this to understand the methods you've described. If you have the patience to educate me, I'll reference your answer:

If you choose the mpeg2 DVD export via Vegas
(Is that the same as choosing render in VMS and choosing MPEG2 and the NTSC DV tempate setting?)
, it will only export the v ideo. You then need to export the audio in AC3. (How is this done?)

If DAR supports that and it puts them back together afterwards, I would suggest you do it that way. ( I have another post explaining the ability to burn the DVD by putting both files back together, but the article did not say how to render the audio and video separately and I've been unable to locate anyone able to tell me how)

Otherwise, I would suggest you export out of Vegas with a lossless codec (I don't know enough about codecs to even know where to begin, both in locating another codec or how to properly decide which codec would be worth trying and which would be a waste of time}

rather than DV AVI which is lossy. Then DAR can do its re-encoding in a lossy codec, mpeg2, only once.

Yes

>audio in AC3. (How is this done?)

You export in AC3 from the "Render as" screen. There is an AC3 filetype there. If it's not, it's because you don't have DVD Architect installed. DVDA comes with Vegas you see, so I don't understand why you are using DAR in the first place.
