I'm doing quite a bit of guessing here. But If you pull the card out and look at it, you may be able to find the chip the does the analog to digital conversion. I think it is a Philips saa7108. It...

@Master Yoda
I take it there is a saa7108 chip on your card. If that is the case, then your hardware is really quite good. From what Wilbert is saying, Philips resizer works well. You can find...

I don't have a Hauppague, but I'd read the following site before I gave up. I'm not sure you can cap anything but mpeg with that card, but you can edit mpeg.

Re: Re: Philips 7133 card and VirtualVCR
I think this is a possibly incorrect assumption.
MPEG is indeed 4:2:0, but you should verify if your mpeg2 encoder accepts YV12 as input. If it does not, your YV12 must get upconverted to YUY2 or...

Can you do 480x480 at 29.970 ?
That's what I'd try.
Your source is 29.970 Frames per second, so I'm not really clear what lowering the frame rate does. It probably just throws away frames...

A gui based one sounds good. Real usefulness is all about how you can view and tweak. I never tried to do the line drawing, because I was afraid it would be too slow.

This should only happen if you are converting from YUY2 to RGB. Some times it is impossible to avoid this, like if you are using TMPGEnc.

RGBAdjust is a good option because it pulls down the red in a way (multiplication) that reduces the high...
