Pre-processing The best way to get high-quality results is to carefully analyze the source media and apply the appropriate pre-processing and encoding filters based on the specifics of the material. This chapter addresses the pre-processing steps you can use to improve your material. See "Encoding" on page 141 for suggestions on choosing frame rate, frame size, data rate and other important encoding parameters. When processing video for desktop delivery, it is important to keep in mind that a computer screen is neither a television set nor a movie theater. You need to create and process video material with the characteristics of your delivery medium in mind. For details on shooting video for streaming that encodes well, see "Shooting Video for Streaming" on page 13. Use Cleaner filters and adjustments, such as Adaptive Noise Reduction and contrast adjustments, to optimize the video for encoding. Working with DV and other non-square pixel material requires special handling to prevent distortion. Fortunately, Cleaner has features that automatically help you work with DV material. See "Aspect Ratio Correction" on page 34 for details. If the source media is captured from tape, you also need to compensate for differences between television video and computer video, such as de-interlacing and adjusting black levels. If originally shot on film, Cleaner can remove the 3:2 pulldown to correct the final movie. See "Using Intelecine" on page 66 for details. For the best final results, crop any black edges or garbled pixels surrounding the image if they are present. Trim the beginning or end of the video capture by setting the In/Out points. See "Cropping" on page 39 and "Trimming Files" on page 42 for more details. Click the check box next to the filters to activate them. Choose Custom from pulldown menus to access additional controls.
