Render settings to avoid DVDA recompress?

hackazoid wrote on 2/1/2010, 3:15 PM
Amateur with my typical 18 min family project of pics and vids. Tried a different sound setting, the AC3 Pro, with my custom SD widescreen Mainconcept MPG2 in DVDA Architect template setup like I read in some other posts.

Rendered fine, but unlike past experiences, over at DVDA, it warned of & then did a recompression. Took 40 minutes and quality seems worse.

Is this due to the new sound format? Maybe go back to PCM?

Should I have selected some different settings?

From researching posts, it seems like this was setup OK, but the technical discussion is above me.

Thanks for the help.

If you've done this before using MPEG2 files in DVDA that DID NOT recompress the video, then what changed? DVDA will recompress AVI files or other formats but it should not have to recompress MPEG2 done with the DVD Architect templates in Vegas.. The audio recompress would be separate and not take long. DId you perhaps do something like turn "reduce interlace flicker" ON or something to cause the video to do a recompress in DVDA ?

Thanks. I used to use other audio settings.

But... you may be right on the flicker. I recall that being checked. Presume that should only be done in Vegas.

I'll re-do without that and see. I thought it might have been the audio change.

Appreciate it!!

Always use the DVA template for video and then render the audio secondly. You won't have a problem

Just to close the loop on this for other readers.

Yes... it was the 'reduce interlace flicker' that I had inadvertently checked & turned on in DVDA that caused the re-compression.

Using the separately rendered AC3 audio file vs the prior WMA ones I used to do was NOT an issue and it worked fine alongside the MPEG-2 video file.

This time I got a DVD in 3 min vs the 40 min for the recompression.

Now, I can spend my time learning to do menu based DVDs using the chapter markers I added for the first time!

Again... thanks to the people who helped---that's what makes this forum so useful. Much appreciated.

I thought reduce interlace flicker was just for DVDA menus. Are you saying it also applies to the timeline media?

I'll defer to XBERT who suggested that, but it does seem that applied to all, hence the recompression.

Maybe there is some setting to target it to just the menu?

I used to apply Reduce Interlace Flicker in Vegas but decided it was easier to just check that in DVDA. Is it better to apply it at the project of track level in Vegas than in DVDA? What is the difference?

Again, I'll defer to the experts as to which has the best results.

But, in my case, the DVD burn took 12x the time (40 min vs 3 min) so if you make menu changes or other tweaks at that level, it may do it again which takes a lot of time just when you are anxious to get the final product.
