Dvix to SVCD or VCD hell

[Codecoder]

See what I meant? Using any program possible with any output settings possible I get that very same result. 90% of the frames are very good like the bottom snap, the other 10% are crappy like the top snap (both snaps are JPGE compressed)

Source 640 x 480 23.xxfps encoded with 3ivx or DIV3 according to VirtualDubMOD. Audio is 48Khz. Target is VCD or SVCD to watch on TV. Just gave up on (K), it just gave me more trouble with non-standard settings.

Is there a question ?

Source file stats ?

Encoding settings ?

What program you're using ?

More information please.

[Codecoder]

Yes, there is a question: What is that thing happening to some frames after converting source to svcd or vcd?

Added two more snaps http://www.angelfire.com/ab8/mymovies/mymovies.html Now you can see exactly what is happening, between the two frames there is a difference of miliseconds or less. I don't know how to call that blockyness.

[jimmalenko]

blockiness/pixelation. generally caused by insufficient bitrate. I say again:

Source file stats ?

Encoding settings ?

What program you're using ?

I got a solution.

Buy a DVD burner.

We are all short on money from time to time but even a high quality burner (like the Pioneer DVR-108) can be had for about $100 or less these days.

So you have no real excuse not to upgrade to a DVD burner.

Hell you can even get Taiyo Yuden DVD-R media (one of the best if not THE best DVD media on the planet) for less than $0.50 cents now.

VCD and SVCD suck donkey balls.

As for the problem you are having ... if you must stick to VCD/SVCD ... the only thing I can think of is that you might be using a DC MOTION PRECISION of 9-bit or 10-bit which is a bit high for the VCD/SVCD formats. Try setting that option to 8-bit instead. If it already was 8-bit (I know for instance that TMPGEnc Plus defaults to 8-bit when using the SVCD template) then the problem is obviously something else but this is worth checking into.

I recently discovered something very interesting. Someone on here has been asking for some help with creating a SVCD and had had problems using the free MPEG encoder bbMPEG so I gave it a try with a capture of mine for shits and giggles (I have TMPGEnc Plus and CCE and mostly just use CCE now and I been doing DVD for a long time ... haven't done SVCD in a LONG time). I wanted to try bbMPEG though to see what kind of quality this person was getting plus I have not tried to make a SVCD in a long time so ...

I actually got pretty amazing results (for the SVCD format that is which isn't saying all THAT much) using bbMPEG and I don't recall messing with the default settings all that much other than setting it up for a SVCD encode.

When I used TMPGEnc Plus with the same capture file (using the SVCD template) I got really ugly results. Not sure why that happend though! Never had trouble in the past but in the past I was always working with ripped DVD videos. By the time I got into analog video capture I had a DVD burner and never tried to make a VCD or SVCD from a capture. I don't have issues with converting my analog captures to DVD video format. So I have no idea why TMPGEnc gave me shit results. I have to test that further but really my interest in SVCD is not that great.

Anyways ... I used a CBR video bitrate of 2300kbps with bbMPEG but then the person asking for help said he was doing a CBR of 1900kbps so that is the bitrate I used with TMPGEnc Plus but I don't think the problem I had with TMPGEnc Plus had anything to do with the lower bitrate.

So what am I saying? Maybe give bbMPEG a try. Just make sure you convert your audio (before you input it into bbMPEG) to a 16-bit stereo 44.1 PCM WAV audio file. With a video bitrate of 2300kbps (audio for SVCD is "fixed" at 224kbps MP2) you should be able to get about 40 to 42 minutes on a single standard 80min/800MB CD-R disc.

P.S.
You can probably up the video bitrate to 2350kbps but I wouldn't go higher than that otherwise you risk going out of spec which could ... and I stress could ... cause playback issues on a standalone SVCD capable DVD player.

Damn. Soon I will be forced to upgrade to DVD burner as well. But yea, lik ehe said, VCD and SVCD suck (but CVD will always lkive on!). I just backup to divx for now. I should probably learn how to back up to DVD now so I don't sound like a stupid noob a few months from now!

[Codecoder]

WT....??? Bbmpeg did it!!! Don't know what bbmpeg did do in the conversion process but the bad frames are gone!

Good bye VCD and SVCD, I'm gonna go for CVD now.

A thank you would make me feel all warm and cozy you know 8)

LOL !!!

Thanks LS

I feel better now 8)

Found the answer. The bad frames are a source flaw, but since I'm not making DVDs which are able to take advantage of very high bitrates, the bad frames become much more visible after converting.

See? It's a 3ivx flaw.
