Note: After you have captured your video but before you start editing, check the burned-in key numbers and timecode to make sure they match the actual ones on the film and videotape. There are a variety of reasons why the window burn values might not be correct, ranging from incorrectly entered values to faulty automatic detection. Any errors at this point will result in serious problems when the negative is conformed. The most common way to verify these numbers is to have the lab or transfer facility physically punch a hole or otherwise mark a film frame, note its key number, and compare it to the burned-in key number when viewing the transferred video. Make sure you verify this at least once for each camera roll (preferably for each take). Compare the timecode in the window burn with the value the videotape deck displays. Speed Film normally has a frame rate of 24 frames per second (fps). This means a new image is exposed or projected 24 times a second. To ease conversion to video frame rates, it is common to run the film at rates other than 24 fps during the telecine transfer. Cinema Tools supports film transferred to video with the telecine running at the rates of 23.98 fps, 24 fps, 25 fps, and 29.97 fps (often referred to as 30 fps). See Frame Rate Basics for more information about frame rates. Editing Film Using Traditional Methods The traditional process of editing film has changed little over the years. Although the equipment has improved dramatically, the steps are basically the same. Following is a simplified workflow outlining the film editing process. Note that the original camera negative is almost never used during the creative editing part of the process. The negative must be handled as little as possible, and then by professionals in the proper environment, to avoid damaging it.
