70 Chapter 6: Pre-processing keyframes. When using these codecs, some pixel movement in the static areas during keyframes is normal. Watermark It is sometimes important to watermark your video or still images to ensure that viewers know who owns or created the files. The watermarking filter applies a watermark to movies or still images by compositing the watermarking graphic directly onto the image or video track. It supports up to 24-bit color watermarks, as well as opacity control of the watermark via the alpha channel of the watermark image. To create a watermark: 1. Create the watermark image in a blank canvas that is the size of your movie with an imageediting application. 2. Add an alpha channel to define the transparency. Depending on the program, black areas are totally transparent and white are totally opaque. This is the standard, but you should experiment to determine how your image-editing application handles alpha channels. Gray areas are translucent. 3. Save the image as an uncompressed PICT file at 72 ppi. Make sure to include the alpha channel while saving the file. If you set the resolution of the watermark differently, you may get unusual results/poor watermark image quality. 4. In Cleaner, select Watermark in the Image tab of the Settings window. 5. Click Set and select the PICT file you just created. Note: You can use Dynamic Preview to see how the watermark appears in your video. 6. Process your file as normal.
