Poor VCD Quality

[Kaluha]

Hello,
I am having trouble with boxy video.


I have been reading a bit about improving the quality of my VCDs and it is still not great quality. I have upgraded my computer to an aphlon 950 with 256 ram. I have increase the bitrate and that only helps marginally. I downloaded the sample VCD from this sight and I would consider that a complete success.

I download video from my digital camcorder using Ulead MedioStudioPro6. I use the same software for editing and creating an MPEG-1 NTSC or VCD (I have tried both). From here I burn the VCD using Nero.

Can anyone help me improve my video quality? I don't know what to try next!!!

Sorry can't help you, but I noticed no one has even replied with any suggestions so instead of starting a new topic with the basic problem as yours I will just add to your post...
I capture with a Pinnacle Studio PCTV with Vdub @ 320x240 with Huffy codec and no filters the capture is from an 8mm camcorder (non dgital)(home movie) the captured AVI is a little grainy but very liveable, now from here I run the AVI through TMPEGEnc to make it VCD (mpeg1)compliant after this conversion the resulting mpeg is very poor quality compared to the original AVI...rather blockyish (I guess) and color washed out..I have read help on this site and adj. settings to their highest yet with no quality improvement I have also ran the AVI through Vdub using different filters to see if it could help but still get a terriable mpeg when run through TMPEGEnc ...any help is greatly appreciated.

Thanks,
Mike

In reply to Kaluha: Things u can do to get better quality.
1. Save the edited movie in Dv format if your harddrive has enough room.

2.Then encode to Svcd with Tmpgenc's svcd template.

I use ulead video studio, P2 350 processor and can get good quality svcd on my pioneer standalone. You can try a short clip and see the result.

he captured a 320x240 file, why the hell would he want to make it svcd

Kaluha,

IMO, the mpeg encoder in MSP6.0 is poor. It can't provide the reasonable VCD quality.

There is great improvement in ver6.5. I accept the VCD quality. However, it perform 85% quality compared with TmpgEnc.

I agree the good method is to save your edited movie to DV AVI format (assume you capture them at DV AVI format at beginning). Then, encode the final DV AVI file to VCD mpeg/ SVCD mpeg by TmpgEnc.

Best Wishes,
Vincent

Thanks for the advice. Using TMPGEnc has improved the quality of the picture alot. I used the AVI file which was 720 X 480 and I reduced it to 352 X 240 to create a VCD rather than a svcd. The only problem was that my Audio sounded like a chipmunk even though the video wasn't fast. Any settings I should change?

Is there any other advice to fine tuning settings on TMPGEnc for VCD and SVCD that anyone has.

Additionally, if you are using another codec when capturing your AVI and the quantize matrix (or DCT blocks) dont line up pixel perfect you will tend to get an accentuated blocking effect when encoding to MPEG. Thats why there is the DCT pixel matrix inside Tsunami.

The cheats way around this is to soften the block edges.

With huffy, its not too bad as its primarily a lossless codec that basically runs on DCT run length encoding.

I have gotten very decent video quality on SVCD from a DV Avi source. The problem is the audio cuts out after about 30 seconds for the rest of the video. What is happening?

Kaluha,

Do you mean you audio noise like metallic sound? If yes, I think it is because the sound conversion from 48K or 32K to 44.1K. TmpegEnc can convert the sound correctly.

TmpegEnc can add external converter. Pls try SSRC. In my experience, the problem can be solved.

Following is the discussion about SSRC. And I hope it is useful for you.

Typing error correction:
TmpgEnc CAN'T convert the sound correctly.
