Still images problem, help!

I'm using Vegas 6 and I'm in the process of making a slide show.

My problem is when I render the video (as raw DV .avi) and open up the file on windows media player, the picture in the video looks degraded from what it actually looks like as a jpeg.

Can someone please tell me how I can get the original image resolution look to the video?

The short video:

Theses are my settings:
1. For the image I checked "match output aspect" and under the image properties it's set as the following: None (Progressive scan) & 1.0 (Square) pixel aspect.

2. Project propperties set to:
Field Order: None (progressive scan), Pixel aspect ratio = NTSC DV 0.9, Deinterlace method = None, Rendering quality = Best
 
When building a slide show, make sure that you use Pan/Crop for all of your zooming and panning. This will give you higher quality than if you try to zoom using Track Motion as Pan/Crop will use the full resolution of the image.

Hi, did you check out the video?

I actually did not use any pan/zoom function for the video on the digital image. The video shows the image in a still position, but I don't get why the quality gets degraded when I render and export it as a raw avi file. Any help would be appreciated.
 
..dont lie to me .. you installed it.. didnt you.. you installed it and you liked it!!! youll pay for this.. youll pay dearly!!!!.


hmmm. alot of people having issues with incorporating still images into PPRO lately too. the same sort of issue with low resolution redering. im trying to figure out if theres a common thread that ties everything together.
 
How big is the original image? How much was it scaled down? Did you apply "Reduce Interlace Flicker"? Any other information that might be helpful?

What's the final destination? If it's TV, did you look at it there? If it's computer, did you change the project to Progressive? TV output will flicker like that on a computer.

Original image size is 1600x1200 but I scaled it down to fit onto 720x480. I've also tried resizing the image on photoshop to 720x480 and the end result when I render looks the same as before.

I've tried Reduce Interlace Flicker, but the photo in the video looks no where as crystal clear as the original jpeg file.

My final destination will be on the computer and I ensured the settings were set to Progressive. I will post a screen grab when I get home later today.

"iamaloser" - if you can find a common thread that would be greatly appreciated.

Any ideas guys?

Thanks,

Mike
 
Try using "sub pixel rendering":

Select VIEW, then VIDEO BUS TRACK.

Right click on the new track that appears, select INSERT/REMOVE ENVELOPE, and then VIDEO SUPERSAMPLING.

An envelope curve now appears. Apply the curve ONLY to the parts where the moire/blurriness appears. Experiment with how much you need to make it disappear. The more you increase it, the more rendering time will increase.

Maybe this will help?
 
Video supersampling is only useful to smooth the motion of generated media, and will not help reduce flickering.
 
Try it. With non-moving stills sometimes it helps, sometimes it doesn't.

The way I read the problem, there's aliasing because the image resolution and video resolution "conflict".

By using supersampling, the image is rendered several times, and averaged so you get better image scaling.

But you'll have to try it. Aliasing is mathematically linked to the relative image sizes. If aliasing IS the problem, then this will help.

Another solution (if there's no panning or zooming of the image), is to scale it to your video resolution in photoshop.

Media Player has sucky DV playback, especially if it's scaled fullscreen. This could be the problem as well.
