Vertical Line Breakup

[reinhold]

Hi

I have seached for this topic but haven't found it.
Version VS8.

Before I had firewire I captured footage by USB using VS8.
It played back okay.
Capturing the same footage by firewire in VS8, verticals resemble flights of steps.

If I capture the same footage by firewire using Sony supplied software,
this problem does not occur. It plays back very well on Windows Media Player and, at the other extreme, on Avid.

But, if I import this captured video into VS8, the ladders re-appear.

The footage is shot on DV and, if I use VS8 to capture it, I have the DV option selected so that there is no change of format.

Any clue would be appreciated.

Have you tried changing the DV Encoder Type. For some strange reason, Ulead seems to have set Encoder Type 2 as the default method of capturing DV format, yet this encoder seems to cause the most trouble to the most people. What is more, Type 2 DV is not needed except by a handful of top-end users and a couple of third party programs that cannot process anything except Type 2. Anyway, you can change the encoder type in the Capture page, under the Options cogwheel icon about a third the way down the left hand side of screen.

The only other thing this sounds as though it might be (to me at least) is a Field Order problem. I am told that some Sony cameras (which I assume is what you have) capture digital DV using Upper Field First, where the majority of DV cameras use Lower Field First. I am not sure about this as I have a Sony digital camera myself (as well as a Canon) and both capture Lower Field First. But getting the Field Order wrong usually results in a 'sheared' effect on the edges of images, particularly when motion is involved. VS should normally detect the correct Field Order automatically, but sometimes can get it wrong. If changing the Encoder Type does not correct your problem, then try changing the Field Order manually.

Thank you for your reply. which I am reading at the conclusion of the Australian Open.

This is a good point. I shall try setting the encoder to Type 1 and see what happens before trying out your second suggestion, which looks very interesting. You point out:

In this case, motion was involved since the the problem occurred during pans.


I have taken your advice about installing firewire and it works well.
