Note: Occasionally there are clips with individual frame durations that are longer than they should be. This situation can cause the Reverse Telecine feature to report one or more dropped frames, when in fact there aren't any. If you see this message, try using the Conform feature to conform the clip to 29.97 fps before starting the reverse telecine process again. The Conform feature ensures that all the frames are the same length. See Using the Conform Feature for more information. As long as you created a new file (by default, with the extension .rev) and did not delete the original file, you can perform reverse telecine a second time if necessary (for example, to try a different field setting). To prepare to use the single-clip Reverse Telecine feature a second time 1 Disconnect the current reversed file from its database record. 2 Connect the original file to the database record. 3 Rename or move the current reversed file if you want to keep it from being overwritten. Now you can perform the steps for using the single-clip Reverse Telecine feature on a clip in Cinema Tools as described previously in this section. Checking Your Reverse Telecine Results After a telecine 3:2 pull-down transfer, the upper field is typically field 1 and the lower field is field 2, except when using DV. Normally, when the Standard Upper/Lower checkbox is selected, Cinema Tools determines what needs to be done and the clips are processed correctly. However, on rare occasions, video is captured or processed in such a way that field orders are switched, and this can result in flawed reverse telecine results. To check your results, look at the frames of a clip that has been processed by reverse telecine. As you look at each frame in the clip, you should see the sequence of A, B, C, and D frames repeat and each letter should be clearly legible. You should not see any interfield flicker. The film frame numbers should increase sequentially, and those digits should also be clearly legible. If not, try using the reverse telecine process again, but without selecting the Standard Upper/Lower checkbox. Using Reverse Telecine on Source Clips in Final Cut Pro Final Cut Pro includes a menu command that allows you to perform reverse telecine on the clips selected in the Browser.
