Import from Sequence Editor

Top  Previous  Next

Selecting "Migration Tools", then “Import from Sequence Editor” from the Pixel Editor's Sequence menu allows you to move effects on RGB props from your Sequence Editor file to your Pixel Editor file. Remember that in S4, within a single sequence, a prop can be sequenced using the Sequence Editor or the Pixel Editor, but not both. So by using this function you are saying: I no longer want to sequence this prop with the Sequence Editor and will use the Pixel Editor instead.


Here is what makes this a desirable approach: RGB props often have many channels and sequencing them in the Sequence Editor can cause the LMS or LAS file to get very large. Large files take longer to load and can be hard to manipulate in the Sequence Editor.


Moving RGB props to the Pixel Editor can allow for much more efficient sequencing:


more efficient in the Sequence Editor because you are sequencing just the channels that need individual channel control

more efficient in the Pixel Editor because hundreds or even thousands of pixels can be easily controlled with a single effect


Using this function should be part of a 4 step process:


1.Make a backup copy of your Sequence Editor and Pixel Editor files. The Save As function can be used for this purpose.

2.Use the “Import from Sequence Editor” function described here to import the channel data into the Pixel Editor. This step does not make any changes to the Sequence Editor file (that comes in step 4 below).

3.Verify that all of the data was imported correctly by playing the sequence in the Pixel Editor.

4.Use the “Remove prop channel data from Sequence Editor” function described in the next section to remove the data from the Sequence Editor LMS or LAS file. This will reduce the size of the file and inactivate the channels that were migrated.


After selecting the menu item, you will be presented with the window shown below. In the grid will be a listing of all of the props in the Pixel Editor sequence. For each prop it will show the number of channels that the prop definition contains in the Pixel Editor (PE Channels column), the number of matching channels that it could find in the LMS (or LAS) file (SE Channels column), the delta between the channel counts, whether there are effects already defined for in the Pixel Editor for the prop (PE Events column), and whether there are effects defined for the matching channels in the Sequence Editor (SE Events column). The “Import?” column should be checked for each prop you wish to import. It will be automatically checked if the delta column is 0, PE Events is “No”, and SE Events is “Yes”. When you are ready to proceed, click the “Import” button.




As noted in the text on the import window, Sequence Editor channels will be imported if their physical settings (network type, unit ID or universe number, and circuit number) match those of a Pixel Editor prop. Therefore, it is very important that your channel settings are correct in both the Pixel Editor and the Sequence Editor before you proceed.


If the import window is showing a non-zero value in the delta column, you can click the “More Info” button at the end of the row to get a listing of what channels are causing the mismatch. If you thought the Pixel Editor and Sequence Editor channels were defined the same but the import window is showing a delta, then it is probably best to cancel the import; then review the prop definition in the Pixel Editor and the corresponding channels in the Sequence Editor until you find the discrepancy. Shown below is a sample of the window you would see after clicking “More Info”.




After the import process completes, each prop that was imported will have a single Movie effect that spans the full length of the Pixel Editor sequence. This movie effect will be an exact representation of the original Sequence Editor effects for that prop. There will also be an AVI file for each imported prop in the same directory as the sequence. Do not delete the AVI files – they are required to play back the effect in the Pixel Editor. However, the AVI files are not required for playback by the Sequence Editor or Show Player – they only require the intensity data file. Imported effects are shown on the 4 arches in the picture below.




After migration, if you want to replace an effect you had in the Sequence Editor with a new Pixel Editor effect, simply place the new effect on top of the movie effect. In the picture below, new effects have been placed on “Arch 1” and “Arch 2” between the 3 second and 6 second marks (gray color). The rest of the sequence will play using the migrated effects (white). To modify a section, first select the section by dragging the cursor over the desired area, then right-click and choose “Modify” from the pop-up menu.
