Blocks Blocks and more Blocks

[Jho928]

Hi all,I am new to vcd however I seem to be doing ok capturing converting etc.I am having a problem going from VHS to VCD.I can carture fine (no dropped frames)and the avi plays on the Pc beautifully,I then encode to vcd (TMPEGenc)and burn with Nero.When I play back on My Denon 3700 DVD there is alot of blockiness.I tried color correction(in TMPEGenc) according to Shizzon,It helps a little but the picture is getting too dark.Any suggestions,I am using a Mitsubishi SVHS Capturing with a Broadway Card,(using S-video and stereo Rca Cables)Thanks Jim

hey, u should email me, let me help you-

For one, i need to know how long your clip is so i can help better
2nd, i am noticing that if you use contrast 1 base YUV to darken pic, you can then use gamma correction YUV to brighten it back up without blocks.
This tip will be added into the new guide coming soon.

Dont forget to email me and tell me how long your clip is

You don't mention a VDub step: are you filtering out the analog/capture noise with VirtualDUB before mpeg encoding? The filters built into tmpgenc are pretty limited...

Use a light spatial filter to remove salt and pepper noise (snow), and use a temporal filter to smooth color "jitter" between frames. Output to another AVI or frameserve direct from VDub to tmpgenc.

Noise really kills an mpeg encoding - it takes a lot of bits to faithfully reproduce all that high frequency salt and pepper noise which your eyes so readily ignore! If you remove that noise - and ease some of the sharper edges - then your "bit budget" savings can be spent on better quality overall.

Try the Panasonic Mpeg-1 encoder instead of TMPGenc as it is the best to reduce blockiness. The bad part is that its US$80.
