Fast scenes breakup. I have read several guides and have tried to capture with YUY2, RGB24, and Uncompressed.
Steps followed: 1) I have been capturing to AVI, 2) then transcode it to mpeg using TMPGENV (2 Pass VBR) and 3) use Moviefactory to create DVD files and write to disc.
Regardless if I use VirtualDub, or MediaStudioPro to capture to AVI, in each case I get the same result. Fast scenes seem to break up.
Any suggestions will be welcome.
Capturing from: digital cable using a Aver Studio card
Drivers: Conexants BtPCI WDM drivers (have replaced the ones supplied by Aver, as the results were worse and Virtualdub and other software would not work with it.)
Software: 1) Virtualdub (AVI) 2) ULead MediaStudioPro (AVI) 3) ULead MovieFactory 2
Computer: P4 1.6
Memory: 512Megs
Any suggestions will be welcome

When I play it on my DVD player, car chases or a soccer ball being kicked, or a person turning his head quickly around, etc do not get displayed smoothly

When you say "breaking up" do you mean blockies? smearing? Are you de-interlacing your image? does you encoder support interlacing? What bitrates are you using?
It could be just normal macroblocks, or it could be a problem with the way that your mpeg encoding handles interlacing. -
The picture "breaks up".
WIth Ulead I have tried "Progressive franmes", "Field order A", and "Field Order B".
My encoder does support interlacing, and the bitrate is set to VBR 2000-8000kbps.
On a different front, I have successfully used the same hardware and software to convert analog tapes to dvd. -
Ahh.. do you mean becomming corrupt? things everywhere they should not be? Does it only happen on the TV, not in the mpeg on the PC?
If that is the case try reducing the max to 6500 it might help.
Otherwise I'm lost. -
Just a thought -- Ulead Media Studio works with Type 1 AVI,
and a highly non-standard Type 1 AVI at that. I know 'cause I
used Ulead MSP for years before moving to Adobe Premiere.
You might try converting the Type 1 AVI into something else,
perhaps Type 2 AVI, using the freeware Canopus DV File converter.
Then try loading that into TMPG and encoding. If that fixes the porblems then it's Ulead's el bizarro non-standard Type 1 DV format.
Capturing from DV you should always have lower field first, but
if you use the TMPG wizard for DVD format it will automatically
detect frame order so that can't be the problem.
Are you sure haven't messed with any of the internal settings
of TMPGENC?
It's all too easy to get turned around inside TMPG. For instance,
have you checked to make sure the STREAM TYPE is set to MPEG-2
if you're burning DVDs? It's under SETTINGS and in ADVANCED. If you're burning SVCDS you _must_ set the STREAM TYPE to SVCD. (From your description is sounds like you're encoding to DVD-compliant MPEG-2 and burning DVDs.)
If you're not using the TMPG wizard, do a RESET PROJECT and
load the TMPG wizard and choose the plain vanailla NTSC DVD
format, only changing hte bitrate settings. If that solves the problem,
then the problem was caused by some weird settings inside
TMPG that got reset somehow (which is all too easy to do, there
are 8 bezillion settings inside TMPG and if you change one to
the wrong setting, it can mess up your MPG output.)
Other than that, as Snowmoon said, I'm at a loss. I encode 2 to 3
hours of captured video per day using TMPG and burn DVDs and
have never had the problem you describe. With 2-pass MPEG-2 VBR 2000 min 6000 av 8000 max there's just tons of bitrate, the DVD should *never* break up no matter how fast the motion.
One last final thought...could it possibly be that the satellite video you're recording is compressed and that perhaps the source itself is breaking up in fast motion...??? -
Another stupid question... what type of audio compression and bitrate?
