Problem With MPEG2 Output

norm1153 wrote on 2/13/2007, 1:11 AM
Greetings:

I'm attempting to create an HD DVD with a video clip created in Vegas 7 Production. If I render it from within Vegas to an mpeg2 clip, (CBR, 25,000,000 kbps bit rate, 384 kbps audio), the dialog box puts a .mpg extension on the file. However afterwards, the file shows up in Windows Explorer with a .m2t extension. Further, this file is not readable by another program. I've changed the extension to .mpg just to try, but the error comes up as: "File format is not supported."

Is this possibly caused by a limitation of the Mainconcept codec, as implemented for Vegas?

Thanks,
Norm

I do HD all the time... granted I usually render out as M2V/WAV, but the odd time I render out as MPG, and have never had any problems. So my guess is that you have a setting or 2 wrong somewhere.... Mainconcept is certainly capable of doing what you are asking.

In the custom dialog under Video you have the output type set to ATSC. Change this to MPEG-2 instead.

The Video - Output type was to HDV (not ATSC), so I changed it to MPEG-2, 1st choice at the top of the list, as suggested.

When I did this, the CBR went from what it had defaulted to as 25,000,000 to 9,800,000 bps.

However it crashes every time I make that one change to MPEG-2. The error message comes up as:

and of course Vegas 7 is gone; have to start it up again.

Running WnXP SP 2, 2 GB RAM, Intel motherboard.

Any ideas are greatfully appreciated!!

what exact file type (format and specific parameters) does your authoring tool require?
norm1153 wrote on 2/15/2007, 12:44 AM
I need an mpeg2 file, 25,000,000 bps frame rate, audio 384 kbps, 1440x1080i (1080i 60).

The video is captured using Vegas 7 Production from a Canon HV10 HD camcorder.

I'm producing HD DVD's as well. Don't know which authoring software you're using, but if it's Pinnacle Studio 10.7, then you are better off exporting a M2V/WAV anyway. This will allow for studio's smart render to work at its maximum and will COMPLETELY avoid rerendering.
blink3times wrote on 2/15/2007, 4:00 AM
Okay... I just did a few test strips and I understand what you are doing... your settings are wrong.

Under the VIDEO tab you're choosing HDV... this is wrong. You need to choose MPEG2.
You will probably have to reset for 25,000,000CBR 1440x1080, leave all other settings as they are.
Then goto the SYSTEM tab and choose STREAM TYPE: PROGRAM... not TRANSPORT... leave all other settings as they are.
You should also got to the AUDIO tab and make sure you are set at 384, but do not touch any other settings.

This will give you MPG output.
norm1153 wrote on 2/15/2007, 2:46 PM
Aha, that was it!!

I had changed the Video tab from HDV to MPEG-2, but not STREAM TYPE to PROGRAM. When I changed that one (and it indeed was showing Transport), it rendered. It left the ".mpg" file extension on this time as well, and the mpg file was accepted by the HD DVD creation program.

And I've saved this template with a new name.

Thanks so VERY much for your help!!

When I changed my setting to "program" it gives me choice of 15m or 60m on the bitrate tab, not 25m. Which did you select and how does the HD video look? Will I need to do the same for blu-ray? I am thinking about buying a blu-ray writer and am experimenting with the outputs. I will use Nero7 to burn. Thanks for your help.
norm1153 wrote on 2/15/2007, 5:46 PM
Well, following the advice of others who have been endeavoring to make HD DVD's, I changed it to 25,000,000 manually; Constant Bit Rate. For HD camcorder footage, I don't believe there is any payoff to exceeding that, since that matches the camcorder.

It's possible that Constant BR may have to go to Variable BR with the 2nd generation players coming out, based on what others are discovering. There have been some problems reported with discs that worked in 1st generation players, but not in the newer ones, but I have no experience in that.

Could you share what sort of HD DVDs you're making?

What sort of disc, burner, software etc.
norm1153 wrote on 2/15/2007, 8:10 PM
The link below goes to the first page of a lengthy thread that gets you a standard DVD-R with approx. 20-25 minutes of high definition video (1440x1080i). So this is currently only practical for those who want to put their high def camcorder video on disc.

http://www.avsforum.com/avs-vb/showthread.php?t=705146

The first page has the how-to, so I linked to that.

Software used is:
ULead Movie Studio 10+
ULead DVD Movie Factory 5+
Nero 7 Ultimate Enhanced.

I've successfully substituted Vegas 7 Pro for Ulead Movie Studio. However, the exact versions of the software listed are necessary, especially the 2nd and 3rd ones listed.

Basically, MS 10+ is used to capture and edit footage. DVD Movie Factory 5+ creates an HD DVD folder on the disc, and Nero 7 Ultimate Enhanced records the file onto the disc. Again, I need to stress that these precise versions are needed in order to achive success.

It's a long thread, and others have had more experience to date, than I have. The process works fine on first generation HD DVD players, but has given some skipping/stuttering problems on 2nd generation players, specifically Toshiba's A2 and XA2. They play fine on first generation players, and the XBox 360.

The author of the thread claims success on 2nd generation players by changing from CBR to VBR, and his discs play on an A2. Interestingly, after purchasing the Toshiba A2, he went through all his discs, and only a small number displayed stuttering and/or skipping problems. Others report total failure with their discs on 2nd generation players, which leads me to wonder how closely they followed the "proven path" of authoring. But I am still feeling my way along, myself.

Hope that helps.

When you choose MPEG2, it will default at some numbers can't off hand remember what they are, but there is nothing preventing you from making manual settings. You can customize yourself a COMPLETE new template to how ever you want.


"Could you share what sort of HD DVDs you're making?"

It's entirely possible to produce REAL HD DVD's on standard dvd media with a standard dvd burner. They are called HYBRID HD DVD's. They are real HD DVD's in every meaning of the word (1440x1080, 25Mb in either pcm audio or dolby surround sound....I use DD5.1 sound)

They will play back on the Toshiba Hi def hd dvd player. They however will NOT playback on your computer. They are written in UDF2.5... although a standard burner can write UDF2.5... they can not read it. You can fit up to about 40 minutes of HD on a double layer disk at 25Mb or you can drop the bitrate a little to 19Mb and get about 53 minutes on a disk.

I now produce almost nothing but hybrid hd dvd's.

NORM:

You should use Pinnacle studio 10.7. It faster and it's a one-stop shop. You import your stuff from vegas, throw it on the timeline and away you go... it even burns the disk... you don't need Nero. Studio 10.7 can also do double layer disks. The method you are using has trouble with DL disks. With 10.7 you can even do DD5.1 HD DVD's

LOL! That's funny when that happens; has happened to me before.

I'll look into Pinnacle Studio, thanks.
