Organizing your Footage for Stereo 3D Playback
IRIDAS 2011 applications automatically find the corresponding footage for the other eye when you drop a sequence into the timeline. In order for this to work, the sequences need to adhere to commonly used naming conventions, like using _R or _L to indicate the eye assignment.
Substitution Table
The substitution list is contained in the file StereoNaming.fcps in your Settings folder.
The file can be edited using a text editor and has the following structure:
Left<TAB>Right
So the word "Left" will be replaced by "Right" to find the corresponding eye and vice versa.
The file is pre-filled with commonly used stereo conventions, so you usually don't need to edit it. There are two scenarios where you need to modify the preset file:
1. You are using a naming convention that is not contained in the file. Simply add another line in the text file and use the tab character to separate the two pairs. As a general rule, keep the substitution table as simple as possible.
2. You need to take out one of the substitution rules because it collides with file naming you use. For example, if your file paths is Test/Test_Layer1, the default substitution table would replace it with Test/Test_Rayer1, which it will fail to find. To remove the substitution rule, simply delete the corresponding line in the file. Make sure you create a backup as installing a new version will replace the edited file.
Default Substitutions
By default, the default stereo naming file allows you to use either one of the following naming conventions in the same position in their fully qualified path:
- "left" and "right"
- “Left” and “Right”
- “LEFT” and “RIGHT”
- “_L” and “_R”
- "lf" and "rt"
- "LF" and "RT"
- "CamA" and "CamB"
- "LinkA" and "LinkB"
- "Link_A" and "Link_B"
The folder naming that includes the Link definition is usually used for Mscope only.
File Path Examples:
Scenario A: both left and right eye are on the same Volume:
- X:\Footage\left\Shot\Version\Test\frame#.dpx
X:\Footage\right\Shot\Version\Test\frame#.dpx - X:\Footage\left_eye\Shot\Version\Test\frame#.dpx
X:\Footage\right_eye\Shot\Version\Test\frame#.dpx
- X:\Footage\left\Shot\Version\Test_L\frame#.dpx
X:\Footage\right\Shot\Version\Test_R\frame#.dpx
Scenario B: left and right eye are stored on 2 discrete Volumes:
Running OS X please ensure to use Volume Names LEFT and RIGHT. Running Windows please use R:\ and L:\ drive letters.
- L:\Footage\Shot\Version\Test\frame#.dpx
- R:\Footage\Shot\Version\Test\frame#.dpx
Linux/MacOS X
- /Left/Shot/Version/left#.dpx
/Right/Shot/Version/right#.dpx
Note: Make sure you don't have any of the replacement wildcards as part of your regular filename, otherwise they will be replaced. These examples would not work:
- X:\Footage\left\Shot\Version\Test\Compositing_Shot_left_Lowres.#.dpx
- X:\Footage\right\Shot\Version\Test\Compositing_Shot_right_Lowres.#.dpx
(The _L in the left eye filename's _Lowres would be substituted with _R, and result in right right_Rowres.#.dpx which cannot be found)
