importing images from Photoshop

Hello, again

I'm working on a project where I'm scanning drawings into Photoshop and then bringing them into VMS 7 Platinum. I've read so many pieces of advice about this that I'm more confused than ever.

Questions:
I scan the drawings and save as a JPEG so I can change the image size to 720 x 534 and then save as a PNG for VMS 7. Does this sound correct.

I've also read where picture images should be 655 x 480 / 150 dpi.

Which should I be using?

Thanks.

Ingore all the advice. It's all right, and mostly unnecessary. How's that for advice?

One thing for sure though, completely ignore "dpi". That means absolutely nothing in video. For example:

720x480 @ 150 dpi = 720x480
720x480 @ 300 dpi = 720x480
720x480 @ 60 dpi = 720x480
720x480 @ 7200 dpi = 720x480
1440x960 @ 150 dpi = 1440x960
4096x3072 @ 150 dpi = 4096x3072

It's only the pixel dimension that matter, not the DPI.

The truth of the matter is, you can use just about any size image you want and Vegas will resize it to fit the frame for you. No thinking needed. The only considerations you should worry about are a) the image is big enough so that if you decide to zoom in, you don't go beyond the native resolution of the image, and b) don't use images bigger than necessary.

a) Say you want to zoom in on just 1/4 of the picture to highlight someone's face. If your video frame is 655x480 then the image should be at least 2620x1920 so that when you zoom in you'll still be using 655x480 pixels to fill the frame.

b) Vegas gets bogged down when opening too many huge images. In the above example, you would need at least 2620x1920, though anything larger would also work. However, if you have too many images that are much larger than necessary Vegas can slow to a crawl or even abort rendering. So, if your images are very large then you might want to consider resizing them down as needed.
