Jittery / Ripple on final product

I have a 1 hr 42 min video. I imported the video from an analog camcorder in .avi format which was about 12gb. In the preview, everything looks fine. There is no jittery or ripple effects when the camera focuses on a subject. I chose the make video option and saved it to my hard drive in MPEG2 format. which came out to 4.6 gb. I then looked at the final product in Media Player, majority of the file is rippled. Has anyone else had this problem? I have 2.6 ghz 1 gb ram. I defraged the hd prior to putting it in MPEG2 format.

Eventually, I will put this on DVD using MyDVD. Would it matter if the source was 320 x 240 during capture and I saved it as 800 x 600.

MPEG2 is interlaced for TV, a computer is not. What you are seeing is an interlaced video signal being played on a progressive monitor.

Try outputting to tape or DVD and see what it looks like. It should be fine.

Thanks for the input Dave, I will try it. If I want to view on both tv and computer, Is that asking too much in terms of I have to pick either tv or computer.

A computers requirements and a TVs requirements differ for quality video. You may notice that sometimes highly compressed video formats, like Divx will look very good on a computer, but a format like DV, which looks great on a TV, will look like junk on a computer.

Also, there is software that will make a TV signal play okay on your computer. Usually, DVD sofware like PowerDVD will handle the translation much better than WMP.

So yes, most of the time you have to decide which medium you are going to use for viewing and cater to that. But there is nothing stopping you from making a computer friendly video file and a TV friendly one.

Something else to check for when working with captured analog video is:

1) Go to the Media Pool and right click on your video clip.
2) Select Properties from the pop-up menu.
3) Go down to Field Order under Stream Properties.
4) Make sure it is set to 'Upper field first'.

Doing this can help to clear up a lot of other problems as well.

Hope this helps...

I tried the 'Upper Field First' seting as suggested - and sure enough - it got rid of the jitter. I also got an eror message about the output file being in error - however the file did get created so I suspect it is just some bug.

That led me to wonder - are there other settings I should be checking to ensure my output is as good as it can be?

In my case I am inputting from an analog HI-8 camcorder through a video capture card & will put the edited video onto DVD.

e.g. - does it make a difference if I set my input size to 640 X 480 or should I set it to a higher resolution?

Also - would I be better off getting a Digital-8 camcorder to input my video (from my existing 8mm & hi-8 tapes) as compared to using the video capture card now that I have teh capture card installed & working properly.

Thanks for the help.
