Pan Stills across screen

Jazzman54 wrote on 12/13/2007, 5:04 AM

I have trouble trying to pan stills across the screen. One of my typical efforts is shown here:

Whenever I generate the output (to DVD) the front edges of the stills show jaged lines or juddering front edges when shown on a Television from the final DVD. As these look like interlacing issues, I have tried all combinations of de-interlacing and filtering. I have even tried using bpm format files instead of jpeg as input sources as this seemed to change things at one stage.

Can anyone provide an idiot-proof way of ensuring a solid still pan from jpegs? The time involved in trying out differnet options, renering and burning to DVD is a very time consuming process and the front edge problems do not seem to show up on monitor outputs. Is there a guaranteed method to do this?

Thanks in advance

My eyes are kind of old but I don't notice any jaggies on the link you supplied. But it could be that the UTube rerendering has slightly blurred your image.

These are the settings I use when cropping video or for still photos:

Project settings:
* Full resolution rendering quality: Best
* Motion blur type: Gaussian
* Deinterlace method: Blend fields

Event switches:
* Maintain Aspect Ratio
* Reduce interlace flicker
* Smart resample or Force resample

I see them on the edges that are on the right side of the pictures moving across and on the bottom of the pictures moving down. I do not see them on the sides that are moving parallel to the movement of your video.

I do not know what is causing that. Have you tried just taking 1 picture and scrolling it across the screen like that without any fx or background media? See if that does it. If so keep adding back the fx and media until you find what is causing it. What are you using to make it? UltimateS? Try it without just to see what it looks like with a simple keyframe from left to right.

Thanks for the inputs. Yes, the problems I refer to are those on the leading edge of the moving images. I have all the project settings set to the defaults that are the settings suggested here.
The problem is not normally noticed by my clients, but I feel it is going to get worse when I complete my first HD project at the begining of January. Any other inputs would be welcome. I will be trying more combinations over the xmas break.
Thanks - Ian

BTW, the video example is produced all in Vegas. Background, generated audio and lots of video layers, using cut and group paste to quickly generate the veg in about 10 minutes.

I did one of those last week using the Vasst Ultimate S plugin and had no problems. It had 4 layers of pictures and was done in HD. The pics did run a little slower though and I wonder if that may not be part of your problem. I also used just a hint of track fade so that you could just slightly see the pics flowing under the top layer of pics.
