VIDEO EDITOR: CHAPTER FOUR 197
Notes:
• When you select a compression scheme, the Keyframe for every spin box
changes to indicate the default number of keyframes the scheme uses.
• Generally speaking, it is best to try out a variety of compression schemes and
options on a test version of the same file, then compare the resulting file sizes and
playback quality.
• For more information on audio, see the ‘Creating a new edit window’ section in the
Audio Editor chapter, page 308.
• If you select new attributes in the Audio Format dialog box and wish to save them
for later use, click the Save As button. The Save As dialog box opens allowing you
to assign a name to the attributes. Clicking OK saves the attributes and the
specified name appears in the Name list.
VIDEO SAVE OPTIONS: CROPPING TAB
Cropping is a useful method for controlling the frame size of a video without having to
resize the actual frames. This is important as resizing frames resamples the original
video, resulting in distortion and loss of quality. The downside though is that you need
to remove data which may or may not be important. Cropping is also good for remov-
ing unwanted noise that may occur around the edges of a video due to bad capturing
or copying.
1. Cropping specifies the area of the video that you want to crop (remove) from the
resulting video file. You can enter values in the spin boxes provided in the
Cropping group box or drag on the control points on the preview image.
2. Keep original size resamples the cropped video so that it maintains the
specified frame size (this does produce degradation however, depending on the
amount of resampling involved). After resizing the control box you can move its
position by dragging it. (Use the slider beneath the window to preview how your
changes affect the video.)
