Steps Figure

1. connect the video source

phylab02b (next to the with Black monitor) is connected to the VCR. If you are using the camcorder, connect it to the RCA plug in the back of the VCR.

2. Start Broadway

it is on the desktop of phylab02b.

It should be in AVI mode as indicated in the toolbar. If it is in MPEG mode, use the dropdown box to change it.

Click "Stop (the square)" to end the capture.

You can use the "in (left triangle)" "out (right triangle)" to mark the section you want. Then hit the "trim" button to cut out the unwanted sections.


5. Save

After your trimmed your video, you can save it as AVI files in case you need to edit it again.

Click the "M" button then to compress it to MPEG-1 file.
