Isadora Manual v1.3 - TroikaTronix

• Set the rendering speed by entering a value between 1 and 100 in the Render
Speed edit text box. Lowering this value slows down Isadora’s internal clock,
giving it more time to finish all video processing before it has to store a frame
to the output movie. This means that Isadora won’t run in real time, but it
allows you to generate output at the frame rate specified in the Compression
Settings dialog without dropping frames. (See Rendering Complicated/High-
Resolution Scenes above for more details on this feature.)
• If you want Isadora to abort the recording process if it cannot achieve the
frame rate specified in the Compression Settings dialog, check the Abort
Recording On Dropped Frames checkbox. Isadora will automatically stop
recording and show an alert box if this box is checked and it drops a frame
during recording.
• Select the Stage whose output you would like to record using the Record
From pop-up menu.
• Select the size of the movie by selecting an option from the Record Size popup
menu.
There are four options: Full Stage Size, Half Stage Size, Quarter Stage Size
and Custom. If you choose one of the first three, the output size of the movie
will be based on the size of the stage. If you choose Custom, two text edit
boxes will appear allowing you to set the horizontal and vertical size of the
movie output, respectively.
If you check the Maintain 4:3 Aspect Ratio checkbox, typing a number in the
horizontal or vertical custom size will automatically update the other field so
that the ratio of horizontal to vertical is 4 to 3.
Note that all of the settings you make here are remembered in the Preferences.
They will be as you left them the next time you run Isadora.
Adjusting the Compression Settings
To set the compression settings for the movie:
• Choose Record > Compressing Settings… to show a standard QuickTime
compression setup dialog. Initially, it will look like this:
