Capture resolutions....pros and cons...

[Macros746]

Hello everyone. I, like everyone, am in search of the perfect TV capture and encode. I bought a signal booster yesturday and so now my Huffy and MJEG avis look truly beautiful. So I am now experimenting step by step to find the best of all settings for capture. I have heard many arguements on other forums about capturing to 640x480 or to 320x240. What are your thoughts. I think the details are a little finer when capturing to 640x480 (I haven't tried capturing any higher resolution than that....)

It depends on what your final output format is going to be.

If your objective is to make the best looking VCDs, then 704x480 is the best format to capture in. If thats not available on your card, use 640x480.
Doing the deinterlace and resize afterward in VirtualDub will maintain more detail than capturing straight to 352x240, since it will take into account information from both video fields. Also, running any noise reduction filters at the higher resolution before the resize filter will produce better results.

And if you've got the HD space, stick with Huffy.

Mpeg is lossy enough on it's own, so you might as well start with the highest quality source your hardware can provide.

Please describe this de-interlace and resize step in detail. How do I do it?
I've tried vdub cap in 480x480, but get bad results, even with overlay off. Lots of comb stuff. With MMC, there's a check box "deinterlace" I can check to avoid the combs,but how do I do this withvdub?

Video>Filters.. add filter

Choose your selection, quick and dirty is a bicubic resize down to half your vertical res, VDub has a nice field bob filter built in. More deinterlacing filters (such as the excellent smart de-interlace) can be found from the virtualdub homepage.
