MainActor uses the system interface for capturing video. If you have more than one capture card installed, you can choose from the list of available drivers in the Driver menu.
The Options menu lets you change specific options of the currently selected capture card. The Video Format ... , Video Display ... and Video Source ... items open special configuration windows supplied by your capture card manufacturer. Please have a look at the online help of these windows for further information.
The Preview item enables the preview mode, the preview mode displays the video the same way as it will be captured, i.e. it uses the same frame rate etc.
The Overlay mode (if supported by your card), uses a specific overlay mode to display the video. This mode has nothing to do with the quality of the actually captured data.
The Capture Audio item controls if audio data is captured together with the video data.
The Record button will start capturing, you can select the name of the capture file first. The Frames Per Second button allows you to change the frame rate of the captured data. If you are in Preview mode, you can immediately see the changes take effect.
After capturing, you are asked if you wish to load the captured animation into MainActor .
Make sure that you choose a compression method for the captured video which is supported by MainActor. This can be done by selecting the Video Format ... item. If you want to have support for a video format of a specific manufacturer within MainActor, please contact us (and the manufacturer) to request support.
