When designing video graphics, it is very useful to view them on a broadcast monitor or television. Starting with Photoshop CS2, Adobe added support for video previews over FireWire. This allows you to perform essential checks for color, interlace flicker, and readability.
' Step 1. Ensure the DV device is connected and powered BEFORE launching Photoshop. You can use a camera or a Digital-to-Analog converter that supports either NTSC or PAL and the DV standard.
Step 2. Choose File>Export>Video Preview. The pop-up window will present you with logical choices (you can rollover an item for a detailed description).
Step 3. Choose an Output Mode that matches your hardware (NTSC or PAL).
Step 4. Set an Aspect Ratio for the monitor. If you have a widescreen monitor attached choose Widescreen (16:9), otherwise use Standard (4:3). Photoshop will automatically adjust the graphics to match the hardware attached.
Step 5. Under Image Options you can specify how to handle when the image size differs from the display.
Step 6. Leave the Apply Pixel Aspect ratio to Preview box checked to get the most accurate previews.
For subsequent previews, just choose File>Export>Send Video Preview to Device. This will use the last settings you've chosen and bypass the length dialog box. Remember, the only way to see accurate video colors is to hook your machine up to an NTSC or PAL monitor. If this is not an option, you will need to test your graphics with another technique.
