Comparing Two Versions of a Cut


Conformalizer will compare the shots listed in the old and new versions of the cut and create a change EDL which represents the difference between the two versions. This change EDL is essentially a list of instructions describing how to conform your data to the new version.

1. Make sure you have both old and new lists loaded in their respective panels and that the 'healing' and 'list type' preferences are set as you wish (see the setup page for an explanation of these settings).

2. Click or tab into the 'change' panel and click the 'compare' button (cmd-K).
Conformalizer will make the comparison and save a version of the change EDL in the 'change lists' folder (located in the Conformalizer application folder). Events which are determined to be VFX updates will display in green. Gaps in the new movie timeline will be shown as GAP events in the list. These events are calculated base don the real events in the list, so they cannot be edited or deleted.



If you ever notice events with red coloured timecodes, this indicates that the old and new timecode ranges do not match. This usually means sombeody has been manually editing timecodes and has made a mistake.

keeping track of VFX shots


The VFX tracing features in Conformalizer mean that updated VFX shots can be traced when comparing the old and new cuts. Without this feature, Conformalizer would decide that VFX_123_021_v11 had absolutely nothing to do with VFX_123_021_v12 and would leave a gap in the conform where the VFX shot should sit. With the VFX tracing feature enabled and correctly configured, Conformalizer will trace the shot as if it were the same piece of footage and will display the event in the change list coloured red to alert you to the fact that this event contains some kind of VFX change. This gives you the opportunity to immediately see the change and decide if the event needs modifying to be more accurate.

Use the 'Smart VFX Tracing' setup fields to let Conformalizer know how your VFX clips are named. Conformalizer will use this information to decide which clips are VFX and to decide which ones are updates of shots in pervious versions of the cut. The setup fields do not require a prefix to be specified but separators between the scene, shot and version are important for the feature to function correctly. An example of how your clip name might look is shown to the right of the setup fields.


Searching for a particular shot in older cuts


Sometimes you may be unsure of which list to use as the 'old' cut. Conformalizer can search for part or all of a sequence in a group of lists and let you know which ones are possible matches.

For example, if you notice that a particular shot or scene has suddenly re-appeared in the cut, you may want to try finding these shots in one of the older cuts from many months ago. Or perhaps a scene has moved from reel 8 to reel 6 and has also been recut in the process.

Conformalizer can perform a full comparison, including VFX, on every EDL within the directory you specify, and then give you a list of any files which contain matches. It will also show the number of shots matched and the total duration matched.

1. Select the events in question from the 'new' panel

2. Choose 'Find Selected Events In Other Files' from the Events menu (cmd-F)

3. Choose a folder containing all the files which you think may contain the shots in question. Conformalizer will recursively scan all files within the chosen folder and return a list of files containing the shots and a tally of how may possible matches were found in each file.

4. Once you have chosen the best option from the list you can hit the "load list as old cut" button to save manually locating it.

5. Compare just the selected 'new' events using the menu item or the keyboard shortcut (shift-cmd-k)



Video Compare - Comparing movies using just video data


If you really, really cannot get a decent EDL then you may benefit from using the Video Compare feature. This algorithm literally watches every frame in both movie files, and then makes a comparison based on the actual pixel data. Smaller selections (such as a GAP event) can also bet set to compare using just video data, in order to catch some footage which was missed by the EDL compare method.
See the Letter To The Editor for details on the Video Compare function and how it reads picture files.
