zooming into jpg - bad quality

nataq wrote on 3/18/2009, 5:45 AM
Hi all,
I have a portrait format jpg (ratio 2width:3height) and I want vegas to pan this image from top to bottom while it is stretched to the full with of the screen (hope that explains it well enough - sorry for my bad English).

I know how to do it (using track motion) - but the quality is just very bad. There is staircasing and pixelation to be seen even though the image itself has a size of roughly 18mpix and is of perfect quality. Should be sufficient for a 1080p video.

I couldn´t find any info in the forum - would be glad is somebody had a different approach!

Thanks in advance,
Wolfgang

Your mistake is using track motion, use even pan/crop.

Track motion works after the image has been scaled to the project size, event pan/crop works on the image at it's original size before it is scaled to the project size.

Hey Bob,
thanks a lot for your help. I also tried the Event Pan/Crop, but with an image that is higher than wide, I just can´t seem to get it to work.

When you're in Pan/Crop, right-click and select Match Output Aspect.
This will get rid of the black bars on the side at the expense of zooming into the image.
If you still want to see the whole thing, zoom out.
The main advantage of doing the match aspect is that you can now zoom in without things being cut off on the sides.

did you, by chance, look in the help file/manual for "pan"?

Hi Mike,
great - thanks for the input, it´s very much appreciated.

And to be honest: no, I didn´t read the manual. I usually read manuals when I purchase a product/software, but not as a reference once I´ve got used to it because the solution I need usually isn´t there :-(.

Thanks again guys!

There is also a thing called "too big". 18 megapixel might be too large for the pan/crop function also. Try to scale it down with Photoshop/other editor to a png just slightly slightly larger than you need.

the manuals with the software sold on this site contain examples, how to's AND pictures of nearly everything in the software. big thing lacking is the Protype info. F1 equals the PDF manual, both identical except how they function.

what I normally do is figure out how much I will zoom in max & make THAT section the same res as the project. But normally I don't zoom much because I plan on how to use my photos during shooting or before I use them.
