Mpeg woes and queries
 
I have tried creating mpegs of my five minute animate short to put on CD-Rs. The only thing I've gotten to successfully play is an Mpeg-1. I was happy with this until I noticed how "blocky" it looked much of the time, despite the fact that I set the video quality to high. I tried making an Mpeg 2 (I have to make these through Vegas Video, by the way) and it won't play on my quicktime player ("because a software component needed by the movie could not be found"). I'd make an AVI file or a .MOV, but I know those will be too large for a CD with high video quality. Any recommendations?

A software component is a codec, meaning the format, DivX etc. is not supported on Quicktime. Are you using the latest version of Quicktime? I think its version 6 for PC. Since I us Macs I can't be of much help on your software. Sorry.

I thought I was. I'll have to see. Thanks anyway.

Mpeg2 is not playable by every player out there yet. Software
DVD players will though! And if you make it SVCD it will also be
playable at standalone DVD players (most of them, not all!)

Josh Bass January 2nd, 2003 10:15 PM

Okay. I have created an Mpeg2 with the SVCD template in Vegas Video. Played it on our DVD player, and ouch does it look nasty! Every second or so everything will get real blocky, then normal, and back and forth.

Many DVD players do NOT support SVCD, most now support at least VCD. VCD is MPEG1 at 320x240 I beleive. I think SVCD increases the resolution thus you are trying to encode more with not much more bitrate. Neither SVCD or VCD will ever look as good even a low end MPEG2 DVD, it is just hard to get a good image at a low enogh bitrate that will then fit on a CD. I put events/shows that are not picture quality critical on VCD, thinsg like comedy acts and stuff where listening is more important that what you are seeing. If I want it to look good there is no getting around going to DVD where you can get a 4-6Mbs bit rate encode that will look very good. And if it is that important I runa 7-8Mbs encode for some very clean looking DVDs.

I think I should be able to fit five and a half minutes of material on a CD and have it look damn good, no?

A Video CD is basically a compact disc that contains movies and pictures instead of audio. A VCD has the capacity to hold up to 74 minutes of full-motion video on a 650 MB CD, and up to 80 minutes on a 700 MB CD. The video is compressed using the MPEG standard, which gives about the same quality as VHS movies.

Super VCD is an extended version of VCD, which uses MPEG-2 instead of MPEG-1 to compress the video. This gives better quality video, comparable to DVD, but also mean that the CD can only fit 35-60 minutes movies depending on the CD size used and the encoding rate.

A VCD can be played in standalone VCD players, and most DVD players. Some video game consoles can also play VCDs with special add-ons. A SVCD can be played on many DVD players, but not all. You can play both VCDs and SVCDs in almost all computers with the proper software.

I would guess that your problems are caused by your encoder (VV3) or your DVD player. How old is the player? Can you try it on another DVD player?

Keep in mind that SVCD is 480x480 (for NTSC) or 480x576 (PAL)
instead of the full DVD resolution. I don't know what the max
SVCD bitrate is, but I usually use 2000 kbps CBR (constant bitrate).
Don't know if you are allowed variable bit rate.

Josh, what bitrate, resolution and encoding mode did you use?
With TMPGEnc I can create quite good looking SVCD files.

Josh Bass January 5th, 2003 05:13 PM

I'm not sure. I have to look into bitrate and all that tonight. I hadn't messed with it before.
Also, would I have to make a full resolution, high quality etc. AVI or QT file in Vegas Video first in order to compress with any program besides Vegas, or can they somehow create files straight from Vegas's timeline?

Rob Lohman January 6th, 2003 08:19 PM

If you use a standalone program like TMPGEnc you will have to
create an intermediate AVI file (or whatever format the encoder
in question uses).

Good luck!

Hey Josh...

I make SVCD's and DVD's all the time that play without a hiccup in my APEX 703 DVD player. Here the proc:
1-Create avi file with VV3
2-Transcode with TMPGenc. Be sure to use a hi bitrate. I ALWAYS use 8000 kbps. At this bitrate, many of the MPEG2 files actually look better than the original avi file. Use the TMPGENc template for SVCD or DVD and modify ONLY the bitrate to the max.
3-Author SVCD or DVD with Ulead Movie Factory. I have NEVER had a failure...and they look beautiful. Movie Factory will allow you to input an auto playing company logo, as well as pausing at a chapter selection screen.
4-BTW....avoid the el cheapo discs...not all of them will play. Verbatim or Memorex seem to work fine...oh, and DVD-RW won't work...only DVD-R's work.

Josh Bass January 7th, 2003 12:00 AM

Thanks. I downloaded the TMPGEnc demo, and made an MPEG2 with it. Looks great!

Rob Lohman January 7th, 2003 08:33 AM

TMPGEnc is great... And cheap! There are also plugins
available for it (for example a QuickTime file reader!!). Also you
can find loads of tutorials and whatnot on the application.

Good luck!

Josh Bass January 7th, 2003 12:48 PM

Okay, this may sound stupid, but what do you mean by "software DVD players? I would assume it means the software used to play DVDs in a DVD ROM drive, yet I can't get it to work on my computer or anyone elses.
