<strong>Appendix</strong> 9: Deconstructing Several Films’ Workfl ows<br />
mistake was not caught until the edit was locked. In export to Pro Tools, it was noticed that the frame<br />
rate was 29.97. This appeared to be a total disaster; however, the fi x was reasonably painless. The<br />
captured footage had never been linked in Cinema Tools. However, the database from the telecine<br />
log was intact. The footage was linked to the database and reversed to 24.<br />
This backward workfl ow is actually used on some projects. When using an edit system that does not<br />
support 23.98 or 24 but only 29.97, often the project is edited at 29.97 and, after the edit, the added<br />
frames are subtracted mathematically. This system is called “match back” and is highly problematic.<br />
In match back, one frame in fi ve is simply ignored. Without matching the pull-down pattern, the<br />
resulting 23.98 is unplayable. But this is only used to generate a fi lm cut list; the video will never<br />
be used. The problem is that rarely does the mathematical edit land on a true fi lm frame line. The<br />
extra subframe is rounded off and sometimes, about one edit in fi ve, it is off by one frame. Projects<br />
that use match back must check the negative cut and resync audio that no longer matches the errant<br />
negative edit.<br />
Help Wanted had reversed telecine after editing and, true to form, some edits moved one frame. But<br />
the audio edit was not affected and the new 24 FPS edit played fi ne, so problems were easy to fi nd,<br />
and fi x, and proved to not be a real problem. And, yet, the audio was now out of sync. This is because<br />
the reverse was done at 24, knocking all the pulled-down audio out of sync. There were discussions<br />
on relinking and rereversing, digitally pulling the audio up in Pro Tools and even exporting and reimporting<br />
the audio at a new speed. It was also noted that the mix would be done with machine<br />
control to a 29.97 videotape, so the project needed to stay pulled down through the mix. Once more,<br />
this seemed to be a disaster, and again the solution was fairly simple.<br />
In spite of the audio being out of sync, the work print and negative were cut and, after the silent fi rst<br />
answer print was made and telecined, the 29.97 video was imported into the Pro Tools session. The<br />
speed of this pulled down video matched the pulled down audio but were positionally out of sync.<br />
The production takes were lined up visually to the new picture. This is certainly not the best practice,<br />
but in a pinch, it may be all you can do. The music and effects also needed to be realigned with the<br />
new 29.97 picture.<br />
When lip syncing in Pro Tools, it is easy to select the audio and set up a loop playback. Now, use<br />
the nudge to move the line one frame at a time until it appears in sync. Keep moving it. You will<br />
fi nd there is a “window” of “acceptable” sync about three or four frames wide. Place the audio in<br />
the center of this window.<br />
Another problem had appeared back when the fi rst double use report was exported. There were three<br />
double uses. Two were fi xed by reediting and removing the double use. The third was not a double<br />
use at all, but an unintentional edit that was throwing off the double use report. All were easily fi xed<br />
and the audio tracks reworked around the reediting.<br />
During reverse telecine, several problems were also found in the original telecine log. This caused<br />
major concern as they threw several shots totally out. When the problem was found to be in the<br />
telecine log, the problem was solved by entering the proper information into the time code fi elds in<br />
Cinema Tools. This kind of problem comes up from time to time, but is found and fi xed before the<br />
picture is edited. In this case, the picture had already been edited and it caused two days of total<br />
confusion. The giveaway was that the reversed footage did not have a clear pull-down pattern identifi<br />
er after the footage was reversed. The Cs were all printed over with Ds. A frames were found to<br />
