HELP!! Too many dropped frames!

[kdiaz]

I'm trying to capture video from my analog camera. Doing it with composite only drops in insane amount of frames and makes the mpeg look really poor...can anyone help me out?

Have you tried capturing with a loss less codec? If not, give it a try. This will require lots of hd space though.

Make sure that your camera is displaying the rate you are capturing at, or the other way round.

Camera is at 25 fps and so is vdub/iuvcr.... whatever. but try a codec like (on a relativly fast machine>xvid) to capture if you need a little more space than using Huffyuv (very greedy, a porcine encoder).

I use XVID:-
Quantizer: 1
Max frames before I-Frame (keyframe): 1
Min frames before I-Frame (keyframe): 1

It uses about 30-40% of cpu power on an AthlonXP 2000+

WDM interface is better for capturing real noisy videos (analog
camera tends to be that way.....)
so if you're on win98 or me,try dualbooting with win2k or so...

i was stunned on how noisy video i could capture on win2k
no way it could be done on vfw interface (win98 or me)

Man did I have some 'noise' issues when capping with my old TVWonder VE care of ATI. It was soo bad, but I had seen other captutres off the internet and they were even worse so I thought to myself, how proud I was that I was capturing at such high quality.

Things have moved on a little since then, now, I dont think analogue capping could look any better. The quality seems pretty nice. Obviously not DVB but en compare' to some of the other stuff I seen floating about. One thing people have got to do better is calibrate their cards better. I leave all of my cards settings alone (sharpness, colour, brightness...) and the colour comes out as a - to the human eye - perfect replica.

what do you mean by a loss codec?

A video codec, in AVI (here) that will not loose any noticable quality. They dont compress video that much so the resulting files can be huge, in the order of 30 gigs for an hours worth.
