A hard question...

[hardrock]

Hello.

How to make a PERFECT VCD? When I say "perfect vcd", understand: when you runs the video in full screen, don't have blocks. I've tried to use huffyuv/uncompressed (avi capture) + tmpgenc/lsx (mpeg encoding) and the blocks still on the video. I've downloaded a video in VCD format and it haves an awesome quality and NO blocks. Please help me!

And thanks everyone who help me in other questions 8)
See ya

Well, do you know how the VCD you downloaded was captured?? Or at least what the source was? If you are trying to capture from VHS that was taped from a TV show, you are never going to get a great picture. I've never seen a perfect VCD with no blocks. I would imagine, that if one was to exist, it would have the following criteria:

1. It was captured from a DVD with something like DVD to AVI in a very high resolution and no compression codec, or little compression (mjpeg etc).
2. The type of video lent itself well to VCD/mpeg (not a lot of motion, not a lot of small details moving around... possibly a cartoon etc).

Your source has to be great quality. As for encoding to VCD, tmpgenc creates the best results, tested time and time again. Since you didn't provide much in your post about the settings you were using in your encoders, or your source, I will advise you to ensure that your motion quality detection setting is at "highest". This makes a HUGE difference in blockiness, and is something that gets overlooked by new people (I have no idea if you are new or not). You can also get the blockiness down by adding a blur filter if you like the results.

Remember most profesional VCD's are capped from the original film source using hardware encoders worth many thousands of whatever currency you use.... However I have got very good (macroblock free) conversions from particuluarly 'clean' DVD's. Unfortunately capping from VHS is a kind of no hope in the quality stakes as VHS quality sucks in the first place, so it's a case of getting the best you can. Try using LOTS of noise reduction.

djnibler:
The VCD i've downloaded is from MTV channel. The quality is very good (i think the who captured, captured from a digital antenna).

Shabubu:
When I make a VCD from DVD, I can get good quality when I convert. The blocks are few.

Today i've tried to use Panasonic MPEG1 Encoder. I've got BETTER results than other encoders. But the blocks still on the video.

And, how I can get a better VCD quality? From a Huffyuv or a Uncompressed AVI capture?

Use tmpgenc on the highest motion detection as I said above, and apply a blur filter to somewhat cover up the slight blockiness if it really bothers you. As for capturing, I would try Huffy, mjpeg, and uncompressed to see what gives you the best results. The reason I say this is that I have tried Huffy, and it looks like ass every time. I have NO idea why people here rant and rave about it (though it is free). The best compressor I have tried has been PIC video's MJPEG compressor. I dial it in to a quality level of 19, and capture at 720 x 480, and then convert to mpeg with tmpgenc I capture directly from cable (Comedy Central), and doing all this, my SVCDs are almost indistinguishable from the original, and my VCDs look pretty darn good... though they are never going to look perfect... you'd need to capture the music video from a DVD, or original master as MTV probably did on their sample for it to be perfect. Your stuck with using what you have as your source... and cable is pretty grainy which doesn't do so well with mpeg (or any digital compression).
