HD and dvd architect(quality)

[John Rofrano]

[Michael Kash] “Now I am using HD and with the recompression DVDA does you can see a lack in quality over a rendered HD video.”

Are you making Blu-ray discs or DVD’s? A DVD has 5x LESS resolution so you can’t expect it to look like the HD source.

[Michael Kash] “I have not experimented with any settings yet in DVDA but only used the highest resolution(720×480) with a 4:3 aspect ratio.”

HD is 16:9… why are you using a 4:3 project?

To get the best quality DVD from HD source, render to MPEG2 from within Vegas using one of the the DVD Architect Widescreen video stream templates. Then render your audio as Digital Dolby AC3. This will give you the best encoding from Vegas. DVD Architect will not re-encode these files and simply use them when burning.

As always thanks for the insight john you been a big help.

Yes I am making DVD’s and not blur ray(have not invested in that type of burner yet.

Yet again you have drivin me to a correct path–I will use 16:9 aspect ratio.

As for the rendering in Vegas I assume AVCHD 1440×1080-60i is an acceptable template? So I should render the audio and video seperately in vegas?
Thanks for the help…

[Michael Kash] “As for the rendering in Vegas I assume AVCHD 1440×1080-60i is an acceptable template?”

No. You want to render using MainConcept MPEG2 with the DVD Architect NTSC Widescreen video stream template.

[Michael Kash] ” So I should render the audio and video seperately in vegas?”

Yes.

I learn something new everyday–thanks for the info john and I will play with that…..

I do have one question John. when I render in that format I get letterboxing on the sides(I believe thats what its called–black dead areas on the side).

For the prodject template I have been using HD1080-60i(1920×1080) and I suspect thats the reason for the letterbox. What prodject template would be ggod quality to use that won’t give me the letterbox problem?

[Michael Kash] “What prodject template would be ggod quality to use that won’t give me the letterbox problem?”

This is caused because HD widescreen is really 16:9 while NTSC DVD Widescreen is slightly wider. The black bars on the sides are called “pillarboxing” as opposed to “letterboxing” which is black bars on the top and bottom.

There are two ways to avoid this:

(1) on the Render As window check the Stretch video to fill output frame size (do not letterbox) box. This will stretch the video slightly to fill the black pillarbox bars.

(2) Drop the HD project into a DV Widescreen project and place a Crop with Match Output Aspect to crop the HD frame to match the DV Widescreen frame.

You could argue that a third method would be to manually crop all the events in the project but that isn’t practical.

Thanks for the corretion I didn’t relize there was a different term for when it was on the sides (revert to comment I learn something new every day).

So first option I stretch it a bit and the second I loose a “tad” on the top/bottom of the video. I will try both and see what I like.

Thanks John.

1440×1080 is a great resolution rate. the 60i is refering to frames per second rate. U should usually try to match what the video was shot in with these aspects. some cameras will shoot 60fps, but most are generally 30fps, or 29.9 something is how it shows up on vegas. The i after it refers to wether or not the video is interlaced or progressive. Interlaced video is one picture that is segmented like stripes on an american flag. Progressive is one solid picture. Progressive is almost always better appearance wise, but can take up more space. with interlaced video u can often see the seems of the video if there is any kind of motion blur. I usually use 1440×1080 29.9fps with the deinterlace mode set to gausian blur. 😉
