Some instructions for BETA testers:


Here are some questions and answers related to screen capturing and further processing of .fvf files in FastCut:


fgrab is slow, it doesn't reach 30 fps even though I have configured it...
- You should have at least 8 GB of free space on your startup hard disk drive. But there are also other causes worth considering.

Everytime I put a fvf clip in the FastCut 'Timeline' it appears pixelated and very poor quality.
- Make sure that you set the 'movie size' in the 'preferences' dialog to the size of your fvf clip (=screen size). The actual output export size may be set later in the QuickTime export dialog. Also make sure that the framerate in the 'preferences' dialog is set to the framerate of your fvf clip(s) or higher. Don't decrease the framerate later in the QT export dialog; this would result in artefacts. If you want a framerate of 15 fps for instance, then capture the screen with 15 fps at the outset.

How to get the associated audio comment of a .fvf file into the FastCut 'Timeline'?
- When you have already inserted the .fvf clip into the timeline ('Movie' > 'Insert Screen Movie') it is easy. Just drag and drop the fvf clip from one of your video tracks into a audio track while holding down the option key to perfrom a 'drag copy' operation.




Please delete all old versions of FastCut, fgrab and fvf_player to avoid undesired conflicts.

The applications in this zip file should pass Gatekeeper, if not, please tell me. All .app files should be code signed.

Please test 'Game Mode': Hit the 'Record' button in fgrab while holding down the shift key. Thereby every 1/fps second the full frame (C frame) will be captured. Open the files in fvf_player and check the framerate (look at the window title bar).


The 'jump to key' button in the fvf_player moves the playhead to the next K frame. If you hold down the command key the pressing the button moves it to the next C frame. What's that? A K frame is a full frame created with the 'make key' button in fvf_player. A C frame is a full frame generated by fgrab.

Some words on the system requirements. fgrab needs Mac OS X 10.5 or later and OpenGL 2.0 + ARB extention GL_ARB_pixel_buffer_object or OpenGL 2.1. Have a look at the output of the application named 'Console' for this information.
