Main Concept MPEG encoder Video problems

[Dwightster]

Hello everyone. First of all thanks to all whose info I have read over the past few months in getting my DVD system running.

Now, I am encoding captured VHS video (MotionJPEG through a Miro DC-30 PAL card). The encoding works a treat in that everything goes without a hitch.

HOWEVER, on fast movement (eg a pan or zoom) I notice a curving wavey pattern through linear objects. (This kinda resembles the scooby-doo transition when they peice all the clues together). This stops the moment the pan stops. It is anoying to watch so any help in how I can get rid of this would be very helpful.

Am I correct in assuming it has something to do with Matrices and or motion estimation settings?

Thanks muchly for any tips any of you may have.

You should try to post a sample, so we can see what your describing.

And describe your Main Concept settings -- the default settings for high usually work just fine without fooling with anything more advanced.

Also you might try posting on the MC support board -- their guys frequent that board hourly and always respond right away very helpfully.

Footage with fast and complex spatial and temporal movements is hard to deal with, even on film. I don't think you can do much about it, except increasing bitrate. It might help a little, but not much. If you want it to be like as clear as it was shot by a high-speed camera, forget about it.

also try a different encoder: tmpgenc or cce

Agree with MrKGB. Try Tempgen or CCE using 2-pass VBR. It will do a better job of allocating bit rate to these high motion scenes. MC only does a single pass, so that the estimates for needed bit rates is not as precise as a 2-pass encoder.
