Creating movie for PowerPoint Slide

I want to create a movie of digitall photos that will be panned and cropped. This movie then would be imported in to a PowerPoint slide. I have two questions. First, should I set the project properties to Multimedia 320x 240 15 fps or should I set it to NTSC DV 720x480 29.9 fps? Second, what would be the optimal resolution and size of digital photos for importing on the timeline? I would want to zoom in on some of these photos without getting any pixilation.

Thanks in advance and please forgive me for I am a newbie.

If your PP design is already done, try render your video to a size that is close to fit your video window in PP instead of making it 320x240 and scale it in PP. You should not render it to full size NTSC because it makes a huge file and the system might not be able to chew through it all when played back. When I've made PP presentations I've used dimensions around 320x240, 25 fps (I like things smooth), mpeg 1 or wmv.

I use wmv9 at full screen size for PP uses. Quality is excellent

Thanks for the info. One question that I need answered is – What would be the optimal image size and resolution settings for my digital images. I would like to zoom in on some of these photos without having to worry about quality loss?

This is something that you have to calculate for each image, but it's easy to do. Assume you have a photograph in which you want to zoom in on someone's face to fill the screen. Measure how large the face is. Let's say it's 3/4" high. You will want 3/4" to fill 480 pixels. That means that you need to scan it at a resolution of 640dpi. If the photograph is 4x6" you'll end up with an image file of 3840x2560 pixels.

On the other hand, if you have an 8x10 photograph and you only want to zoon in far enough for half of it to fill the screen, you'll need 4" to fill 480 pixels so the required resolution is 120dpi for a fill image of 1200x960 pixels.

If you're taking pictures with a digital camera then you won't have dpi resolutions, but you can still estimate the required image size based on how far you want to zoom in. If you're not zooming at all then 640x480 is big enough. If you need to zoom in on 1/4 of the image then you'll need 2560x1920.

Don't use a higher resolution than necessary. Having lots of large pictures on the timeline slows Vegas down considerably. The extra resolution is thrown away anyway so it's not helpful.
