To setup for video capture, you must first press the button with the un-lit red LED. When the button is pressed, there should be some status messages and progress bar activity in the display area. When the setup is complete, the progress bar and the status will indicate so, and the record setup button will be depressed with the red LED lit. Next you will want to queue up your video source, then start it and press the play button which has the triangle on it. Once capture has begun, the following activity on the display will keep you up to date on the progress of the video capture.

The add_1_min button is used when your video source looks like it might outlast the pre-set capture limit by a minute or two. Each time the button is pressed, the capture limit will be bumped up by a minute. This feature should be used with caution since it could result in A/V streams that are too large. If the automatic-bitrate computation is used, the bitrate will have been computed based on the original capture limit. Increasing the capture limit will not adjust the video bitrate so as a result, the A/V files will be larger than planned. Since the computed bitrate was designed to leave a little leeway, this button can probably be used a few times with no ill effect.  
 
There are multiple ways for capture to end.  
 
1.Capture can be aborted by clicking on the button with the "x". If capture is aborted, the project will not advance to the next stage. The abort function is useful if the video capture was not started at the right time relative to the start of the video source. Once the abort has completed, the capture is still setup, ready to start at the press of the play button.  
 
2.Capture can be manually stopped by clicking on the stop button with the square. Unlike the abort button, when capture is stopped, the project is advanced to the next stage. There is a short time between when the stop button is pressed and when the project is advanced to the next stage while the scene selection and audio encoding finished up.  
 
3.Capture can be automatically stopped by the capture limit set on the front panel area shown below or on the encoding property page . As in the case of manually stopping, when the capture stage is complete, the project is advanced to the next stage.

4.The last way capture may be stopped is after a user specified amount of unchanging video and no audio has been captured. Unfortunately, the unchanging video has different properties from one video player to another. Various approaches are used to detect unchanging video but this feature should be tested with each player before depending on it to actually stop capture. To disable this feature, enter zero or a very large number of seconds. As in the previous two ways capture is stopped, the project is advanced to the next stage when the capture completes.
