 | Sizing still images for video
by Karl ARNDT on Mar 4, 2005 at 8:09:19 pm |
Dear Boys, I have scanned images (4x6) in Photoshop. Do I crop them to 720x480 or 720x530. And do I use the image adjustment in Photoshop, image, Pixel Aspect Ratio, D1/DV NTSC (0.9)?
Thanks for any help, Karl

Be careful with Photoshop's aspect ratio settings, they can be misleading if you don't use them properly. The best thing to do is get your scans to 800x600 and then resize them to 720x486 (or 480 for DV).

Thanks J. Are you saying not to use the Photoshop Aspect Ration function? And do I just resize my scans in image size in Photoshop to 800x600? And then what? Can I crop them to the 720x486? If you could give me a simple step by step from Photoshop to FCP it would be a huge help. Karl

You can use Photoshop's aspect ratio if you want to, but if you don't understand how it works, it will do you no good. For example you are using a square pixel image, you must make sure that your aspect is square, and if you use a rectangle pixel image (say a still from FCP) you must make sure it is set that way.
As for doing it the old fashioned way like I mentioned before.
Scan your image. Crop and scale the image until you have what you want at 800x600. Make sure that Constrain Proportions is checked. Then go to image size and change it to 720x486 (480 for DV). Make sure that Constrain Proportions is not checked. This makes your image with rectangle pixels for video. And you are done. Very easy.

I do a lot of work with still images in fcp and FWIW I size everything at about a maximum of 1000 pixels. This allows me to do a lot of camera movement in fcp (zooms, pans tilts ,etc.) and still maintain pretty good image quality. Regardless of how you size them, if you have a lot of them to do I recommend Dr. Russel Brown's Image processor. It will auto resize and save images as jpeg, tiff or psd's or all 3. It's free and you can download it at http://www.russellbrown.com also LOTS of great Photoshop info at this site.

Thank you Dave. Do you think 1000 is better than 800? I find that I don't move the image very much. Slow and gentle.

Please be aware if you bring an image into FCP, say 800 x 600, you don't need to convert it to rectangle pixels, FCP will do that for you. You only need to worry about that when you are working with 720x486, which mean no movement on the image as it is full frame.

Jared, You have been a big help. Am I correct that at 800x600 the images can be brought directly into FCP?

Yes, you can bring the 800 x 600 image into FCP directly, and it will be displayed properly. However, when you put it in the timeline FCP will automatically scale it to fit. You can go it to the motion tab and change all of that if you want to move it.

1000 to 1200 pixels as a maximum dimension usually works for a vertical still that you want to fill the frame horizontally with. My personal preference is to fill the frame,and do a tilt move, rather than have all the black space.

Dave, thanks for the expert information. A little follow up, what resolution do you use? I have seen the number 150 written about as a good standard. Karl

I always start with the largest, highest quality scan I can possibly have any use for, then you only have to scan it once, you can always size it down. I normally use 300 ppi, but because you are sizing the image to pixels ie. 800 x 600 or whatever, I have not really seen any difference in the final video with a scan done at 150 ppi or 300 ppi -

Dave, I scanned the images at 300 but was resetting for FCP at 150. ie 800x600 at 150dpi. Karl

For sake of clarity, I misspoke when I stated that all of the linked articles discuss all aspects of using still images with Photoshop and FCP. As a set, the do a great job of covering all of the essential info.
I also didn't mention using Motion, After Effects, and so on, for "pan and zoom" effects, which would require substantially more effort to get the same results (unless you're already very familiar with them)....

Dave, once again, thanks! I will check out the links and do some afternoon reading. I bought the pan and zoom tool. Karl
