PICVideo MJPEG settings questions

[W_Eagle]

Hello,

In PICVideo MJPEG, in Subsampling, what's the difference between 1/1/1, 4/2/2 and 4/1/1? Which is best for high quality capture?

Also, what is the meaning of Luminance Quality and Chrominance Quality? What settings are best for high quality capture?

Take care

The help file tells you exactly what each option does, it's very, very helpful.
Click on 'help' and then click the setting you require further information on.
I've been doing extensive testing recently, in fact I captured the same one minute clip 12 times using Virtualdub and different PICVideo settings and these are the optimal settings for me.



Quality 19/20 is not noticably different than 20/20 but produces around a third of the file size.
Good luck, if you use these settings then I've just saved you hours of work/testing, I hope it's of some use
I was capturing anologue from a VHS-C camcorder buy the way but intend to use the same settings for VHS capture.

Hello Pal,

Thanks a lot.

Where are those help files?

Why don't you use "Codec Enabled?

Thanks a lot.

My pleasure

Where are those help files?

To the right of the button marked 'cancel' on the pic I uploaded

Why don't you use "Codec Enabled?

To be quite honest I can't remember, but I know this setting produced the same result as when this option was ticked, so why complicate matters?
Anything for an easy capture, eh?
