Movie Studio
(MovieStudioWidget)
Short Description
This dialog controls the recording of rendered frames to hard disc in BMP format. There are two modes of operation:
- Manual: Specify a number of frames and press "Record Now". The corresponding number of frames is then recorded.
- Automatic: Frames are recorded automatically when certain events occur (repaint, frame-record events of PCInteractionTools).
Usage
Frame Storage Settings:
- Filename: Enter filename (and directory) here. If the file exists, a sufficiently large number will be appended to the filename, as well as the ".bmp" extension.
Options:
-
Match Real Time: If activated, multiple frames are activated in order to match the
measured rendering time. The time will be rounded to the next smaller number of frames and
the corresponding remainders are accumulated. If exceeding one in subsequent frames, an
additional frame is inserted there. This assures an accuracy up to one frame. However, it is
not clear if the measured rendering time always exactly reflects the rendering time for a
sequence without writing bitmaps (the time for writing to disc is not included in the
measurements, however, caching and concurrency effects could affect the measured estimate).
You should cross check by measuring the time without bmp export as well.
The number of replicated frames can be limted with the "max repl." option.
The frame rate assumed for the recorded movie (to match the rendering time) can be specified
with the "frame rate" option.
- Record At PCI Frame Events: If activated, a frame is written to disc whenever the current tool issues a "record frame" event (controlled by the individual tools). (automatic recording)
- Record EVERY Repaint: If activated, every repaint operation writes a frame to disc. Can be used to record interactive sessions. Use this option with care... (automatic recording)
- Incr. Scene Graph Time: This option causes the scene graph time to be incremented by the amount specified in the timeline at every recording event (modulo specified time interval).
Record Frames Now:
This option is used to record frames manually.
- Number of Frames: Number of frames to be recorded. Automatically set if "main win. timeline" is activated.
- Main Win. Timeline: The number of frames is determined by the settings of the timeline at the bottom of the main window.
- Record Now: Press this button to start recording. (manual recording)
