Horizontal Text Scroll is jerking in .wmv-file

[Jeremy Rasnic]

I am not familiar with the consumer version of Vegas so my recommendation may not even be valid.

Have you tried changing the keyframes to linear and setting the smoothness to 0?

Also, is it just the wmv file? If so, what are your render/encode spec’s? What is your project spec’s? If your fps is different then this may introduce some jerkiness. Also, you may want to change it from interlaced to progressive if it is not already.

Hi razz,

thanks for the quick answer…

I tried to render just a text scroll, without any original video. The problem still persists and exists with most of the codecs.

I used the progressive mode and the keyframes are linear. Its a video of 1440×1080 resolution, but the same with lower resolution.

Where can I change the smoothness? Is this the video smoothness (quality)?

For me it seems, that the text ist rendered jerky already. This means that 3 or 4 frames could be the same, then the text moves and again 3 or 4 frames and so on…

Could be that i’m wrong, but at the moment in my oppinion this could be real…

Greets and Thanx,

Hold up….how many keyframes are thre in the scroll?
If there are more than two, it’s entirely likely that it’s the keys themselves that are generating the jerkiness.
Can you send a link to a sample?

Hi,
there are only two keyframes.

A sample is there:

I have many more examples…

Your beginning vertical scrolls are also slightly jerky, just not as noticeable as the horizontal scrolls. I have repeadedly had problems with the vertical scroller but have been able to get smooth horizontal scrolls. What are the specs on the computer and hard drive that you are using?

I recently did some serious scrolling of photos across the screen and they were not smooth, no matter what I did and what I had my preview set at. However when I rendered it out and played it on a DVD player it was smooth as silk? Who knows?
