Capture
Capture methods control recording and still grab functions.
IMPORTANT NOTE: Real Capture Canvas projects built with REALbasic exhibit significantly improved performance when compared to performance in debug builds of the same project. This is due to an increase of overhead when the REALbasic debugger is running and is normal behavior. The built version of the application will work much better and 30 frames per second for DV is typical in built applications.
