Hi. I am a financially challenged technewbie who had a moderately limited success in producing VCDs with my system. My problem is that I am producing VCDs that are losing frames every couple of seconds, thereby producing jerky motion.![]()
My system is as follows:
Pentium Celeron 400MHz
384 RAM
Windows xp
Pinnacle WDM PCTV Pro TV tuner card with WDM Beta driver
PowerVCR II ver3 with upgrade
10 GB on C:
30 GB on D:
DVD Drive
CDRW drive
Nero CD burner
GE 1101 (Shinco OEM that plays all types of SVCD and can be de-macrovisioned)
A long RCA jack that runs from my DVD player to the computer's tv tuner card
A cable that runs into the tv tuner card
An Svideo cable that runs into the tv tuner card.
With the above system, I am able to succeed on my goal of backing DVDs real time, recording TV programs while I am away, and even backing up some VHS tapes.
In fact, I am pretty impressed with PowerVCR and Windows XP. PowerVCR delivers real time mpg encoding and Windows XP is very stable unlike my Win98 at work.
The problem is the final VCD and SVCD product. The VCDs and SVCDs drop frames every couple of seconds with resulting jerky motions and it is quite annoying to watch anything in this manner (poor quality, I can I bear, but dropped frames, I can't). My wife refuses to watch her favorite TV shows like this and I feel the same way with all my DVDs .
My attempt in solving the problem has been to change all the settings in PowerDVD to no avail. I attempted to get help from various sources from the web including vcdhelp.com, IO Magic forum, groups.yahoo.com, powervcr web site and a few other web sites.
My other solution would be Winvcr since it does have better MPG1. However, their software does not run on xp, and I would hate to make another partition for WinME just for that program (besides WindozeME would always crash on me).
I would appreciate any cheap suggestions such as a different type of real-time encoding software that runs like a vcr on xp? or an overclocking software for my cpu that would improve the encoding. Thanks for reading up to here.

You fail to mention if the original Mpeg captures play OK on your hard drive.
This will tell us if the problem is in capturing or playing back from CD-R.
If it's in capturing, get a hardware mpeg encoder like a Dazzle. There's free software to allow it to capture at a specific time so you can record your shows.
If the problem is playing back from the CD-R's, try lowering the bitrate, or a different DVD player, or both. -
only thing i could recoommend iz lowering resoultion or dont select preview wile capturing but if u must preview while capturing....lower your display properties also have u tried using virtual dub to capture in avi then convert to mpeg...i know it will take longer but i'm just giving u suggestions.
also change your image video capture format if its a RGB, using YUY2 is less stressful -
Sorry. I believe the problem is from encoding since the jerky motion shows up even when I play back the capture on my windows media player and PowerVCR.
Regarding the other comment, I am looking for a solution without making further cash outlay as I am a bit financially restrained these days. Thanks. -
There is no way you can produce a good quality VCD or SVCD by encoding them straight at capture.
The best solution is to capture in CBR (fix bitrate) with a high enough bitrate to have a good quality "Master" on your HP to work with.
Then encode your VCD or SVCD with an mpeg encoder. Even by doing this, its impossible to have a block free VCD cause 1150 CBR is just plain to low to encode fast moving scenes.
You will get the best results by producing a SVCD using 2 pass VBR encoding. -
herbapou , oukcapoussca?
i'm interest in your methode and result
what capture card you have ?
i'm not familiar with CBR and VBR , any definition ?
thanks -
You aren't likely to get very good realtime software MPEG encoding on your system. It's a bit too slow. If you want a better quliaty, you'll need to capture to an AVI using an MJPEG codec or something and then convert that to MPEG using TMPGenc after capturing.

CBR = constant bit rate
VBR = variable bit rateAs Churchill famously predicted when Chamberlain returned from Munich proclaiming peace in his time: "You were given the choice between war and dishonor. You chose dishonor, and you will have war."
