HDV to DVD

DefcomDMC wrote on 11/17/2005, 8:05 AM
Desperate for help! I've finished a project shot and editted in HDV. It's 90 minutes long. I believe I can render a WMV and burn it to DVD, but how do I get it to fit? Should I use Dual layer DVD's? Rendering 25 seconds takes 10 minutes on a P4 3Ghz 1Gig Ram, Is this expected? Is quicktime 7 an option? Do I need to download new codecs? What is, overall, the best way to do this?

Also, the 25 sec test WMV's I've done have alot of "squiggle" during motion or pans that aren't present on the preview or when I prerender.

I just started using Vegas for this project, the manual seems worthless and another book has been less than comprehensive. Any advice appreciated.

If you 'burn" the wma render to DVD wont it re-render to mpeg? For high quality SD render to mpeg2 (such as main concept for DVDA) then urn a DVD or just copy the .wma to a data DVD for playing on a computer. Computer playing will be best if you first copy the .wma file to the HD. Someone add more if I am wrong. My DVD player on the home entertainment system will not play .wma unless I feed it from the computer HD. With DVD players that do play .wma I'm not sure if there is another way.

Alright I want to copy the wma file to dvd. How do I get the wma file down to 4.3, or 8 Gigs to fit on a single or dual layer dvd at the highest quality?

It's all a matter of bitrate. To fit 90 minutes into 4.3GB you'll have a max bitrate of 6679.8Kbps. If the audio uses 192Kbps then you have 6487.8Kbps left for video. Maybe an average rate of 6300Kbps would be good to leave yourself a little wiggle room.

To fit it into 8GB you can have a max bitrate of 12427Kbps, less 192Kbps for audio is 12235Kpbs for video. Some drives will probably have a hard time with bitrates over 9800Kbps, so you may want to test it to see how it goes. If your player has trouble try pulling back to 9500Kbps for the video.

A 90 minute WMV will fit in 8 gigs? So should I just render to WMV with CBR?

Also there's a "Render using Networked computers". That sounds good, how do I use that?

And, does anyone know about the "squiggly" video and how to get rid of it?

It's a wedding and I'm tracking people walking down the aisle and they are clear, but the background people are "squiggly"(for lack of a better word".

It also happens at time like the bouquet toss, every thing in the shot is clear and solid but once there's alot of motion, like the bouquet through the air, those objects look "squiggly"

A 90 minute WMV will fit in 22MB if you squish it down far enough. 8GB could probably handle 3 hours of HD video that looks fairy decent. I would use VBR and i prefer the Bit rate VBR (Peak) setting. Set the average bitrate to 6.3M for single layer DVD or 9.5M for dual layer. Maybe set the max bitrate to 50% higher.

Excellent information, now does anyone know about the "squiggly" thing or possibly banding?
Chienworks wrote on 11/17/2005, 10:11 AM
The "squiggly" thing is probably interlacing artifacts. Search the forum for interlace and you'll find several thousand posts discussing it.

Should the render process take a day and a half (literally)? How do I use the "render on networked computers"? Will this help?

Be glad you aren't rendering with Xpress Pro...

On a dual Xeon 3.6 machine with 2 gigs of RAM, 1 minute and 20 seconds of HDV with reasonable effects and color correction, takes 9 hours to render with Xpress Pro. Which is one of the reasons I'm using Vegas now.

I'm coming off using an Video ediTor that didn't need to render, so this is somewhat of a culture shock.

There are several things to sort out here.
First, you should have downloaded the Vegas manual (that supplied with the software is just a "let's get you started" document); the manual isn't 'worthless'.
Secondly, are you wanting a DVD that plays on DVD players, or are you wanting a data DVD that can be played only on computers?
Thirdly, are you wanting HDV or DV image quality on the DVD?

Assuming that you want an ordinarily playable DVD (ie an NTSC standard definition wide screen), you go back to Vegas, select "render as", save type: Mainconcept MPEG-2, template: DVD Architect NTSC widescreen. If you use a dual layer DVD then you can use 8Mbs. You must also render the audio (separately) as type: Dolby Digital AC-3 (same filename "wedding B&J").
Then in DVD Architect you create "new movie" and load in the rendered files. Put in chapter points where required. This will give you a basic SD DVD that can be played without special equipment.

Producing a SD DVD has a variety of benifits, which includes reducing the "squiggly" interlace artifacts to something people won't notice at all (because they're used to them on ordinary TV), rendering times will be reduced and the image quality will be good. Things that increase rendering times are effects, image manipulations, and so on.

If you're wanting an HDV data disk that cannot be played in ordinary players, then that's something else again.

Don't know if this will work on your tearing (squigglys) but it may be worth a try:
I had to add some wide-screen shot footage with standard once. When I made it match the standard I had lots of tearing on any movement at all. When re-sampled with "remove interlace flicker" it cleared it up.
FWIW,

Another thing which may get rid of squiggles is rendering at Best rather than Good - the render takes longer, but its worth it - do it while you sleep.

Render times:

I have both a 3Ghz P4 with 2GB of RAM and my average render rates are about 1:10 - one minute of video takes ten minutes to render - HDV to DV.

I also have an AMD 64 4000+ with 2GB of RAM and my average render rates are about 1:7 - one minute of HD video takes seven minutes to render.

These are both Vegas 6 times. Adobe Premiere Pro 1.5.1 is about twice as fast on average.
