Wierd Dropping frames at low resolution Please help?

[TurboRunner]

Hi,

This is wierd and is pissing me off since i only have 40gb of capture space and it's only about less than an hour of capture at high resoltion.

Here's my problem.

I can capture with no Dropped frames at 704x576 or 768x576 at 32bit colour which is sweat and would prefere to use on my under an hour videos.

But when I capture at 352x576 at 16bit colour I start dropping frames like mad. If i could capture at that i could capture for 2hours and 10Minutes.

That's what i am calling wierd since you should be able to capture 352x576 on a slower machine and you need a powerful machine like what im using to capture at 768x576 and capturing smaller resolution should be a peice of cake.

Any solution.

Also another question what resolution is Pal TV Broadcasted at and Pre-Recorder VideoTapes Recorded at?
Is 768x576 The Resolution?
If it is that means you should be capturing at a ratio of 1.33:1 to keep aspect ratio of image is that correct?

Thank you to all that reply

The broadcast PAL, is 704 X 576, while the Full Pal is 720 X 576 (used on DVD)
352 X 576 is known as D2, CVD (Chaoji VCD) or Half DVD format. Many cards don't support the capture on this resolution. Asus cards are some of them...
With virtual dub you can force your card to grabb on 352 X 575, but most of the times you grabb and resize at the same time, so that explain the dropped frames...
Grabb to the resolutions your card can handle

You can capture at 702 X 576 and then encode to 352 X 576 mpeg 2 (with mpeg 1 is useless, except if you wish to use xvcd)
In theory, the VHS resolution is 352 X 288 lines, thats why VCD has that resolution for standard...
So, capturing with 352 X 288 you get what VHS can give you, and 352 X 576 what SVHS can give you.
In praxis, grabbing with 702 X 576 (or 720 X 576) and then encode to 352 X 576 gives you a little more in quality on standard TV Sets if you use interlace.
For progressive projects, 352 X 288 is almost the same in much smaller files!
Test, read and select what is for you!
