AHHH!! STILL CANT GET IT RIGHT!!

[cooljoe666]

I have tried every way I can think to get that darn PAL VOB to convert to SVCD right. The VOB is ultra clear, perfect. But after converting to SVCD the video is always blocky on action scenes and movements. I have converted with both CCE and Tmpgenc. Always the same no matter what. I even used DVD2SVCD and let it do it all but still the same. I only have these problems with VOB's.

DOES ANYONE HAVE ANY CLUES?!?!?!

Cooljoe,

Can you post up your method please? I'll tell you the way I do it, incase it's the same as yourself.

Also, what bitrate is your final SVCD? I make mine hold no more than 45 minutes of video or else it all goes blocky like you are describing.

Here's how I do it:

- Rip VOBs with SmartRipper
- Open DVD2AVI and open up the VOB files
- Select "Decode to WAV" under audio, and also "UltraHigh" in 48 --> 44.1KHz
- Save the project, so you get a WAV and a .d2v file.
- Note down the framerate (you know it's 25fps PAL, so don't worry) and aspect ratio
- Open TMPGEnc, feed in the .d2v into video and the WAV into audio
- Select 16:9 Display or 4:3 Display as my input aspect ratio (what DVD2AVI told you)
- Select my source ranges (no more than 45 mins), set motion search to "High"
- Select "Keep aspect ratio (2)"
- Adjust bitrate using that blue bar and encode

Here's the guide to it:

https://www.videohelp.com/mpeg2tovcd.htm

There's two things about this guide I don't do. Firstly, the .mpa file from DVD2AVI - I just output as a WAV. I wouldn't think there's any difference. Secondly, cutting. I don't do this - I select my source ranges in TMPGEnc itself and do two or three encodes as a batch. This saves on cutting at the end, and I'm more comfortable doing it. Again, your choice.

I hope this helps. If this is what you're doing already, then I'm afraid I'm at a loss. Someone else is bound to have seen this before.

Thanks alot for your reply. I ahve tried using TmpgEnc and CCE both. Here are my scripts.

Keep in mind that I have tried high and low bitrates bith CBR and VBR 1 and 3 pass. I have tried the settings in TmpgEnc you have mentioned. The video comes out fine and looks good as long as there is no motion. Any motion causes blockiness to reveal itself. I also tried converting the VOB to a DIVX5.11 AVI file and the result was great quality with 'squares'.
The VOB looks perfect when played in any software player, no blocks at all. Is there a certain filter I need to use or what?

Perhaps you'd get better results (not as blocky) with a BilinearResize instead BicubicResize with the lower bitrate?

Bicubic is a better algorithm for resizing, isn't it? Bilinear is always considered lower then bicubic with still image resizes.

If there's a 'motion search' configuration in the conversion program, set that to high or best. I use DvdX 22, and found its motion search on normal to be fast and good for chick-flicks or dramas, but no for action shooties - it need to be better or best for them (which also halves the conversion frame rate = doubles time to convert!!).

I tried the other resize filters but no change. Actually a slight decrease in quality. The video looks good and clear with Bicubic but only gets blocky and distorted with bright moving images. It seems that dark colors arent affected. This wouldnt have anything to do with the resize filter I dont think. I just wonder why VOB's are the only files to give this kind of trouble. Somewhere between the VOB and the SVCD something isn't properly converting the file and it's hard to understand what. Again, this is happening with every program I use.

Bicubic is better if you are enlarging because it sharpens more and gives you a crisper image. He's not doing that though. He's reducing from full D1 to SVCD and recompressing with a much lower bitrate. Sharper images distort more when you resize them smaller and compress them. If he were resizing a smaller frame to a larger size, Bicubic would be the way to go.

sacajaweeda - Good answer, thanks for the clarity (I forgot the bit about resize UP wards... LOL... blonde moment).
