26 VIDEO EDITOR
• The Frame type option determines interlacing properties.
If your final output video is meant for playback on progressive interlaced TV, set
frame type to either
Lower Field First or Upper field First .
If your output video allows for progressive frames (LCD monitors, plasma TVs,
TFT monitors, etc.), use the
Frame-based option. This setting is more film-like
and less complicated to handle when editing or retiming your video.
• You can set the size for the target display and output screen to 4:3 (for
traditional letterbox TVs, computer monitors, or some DV camcorders) or 16:9
(widescreen used in HDTV, theaters, or some DV camcorders).
To use the 16:9 display, select
Perform non-square pixel rendering on the
Video Editor tab first and choose 16:9 as the display aspect ratio on the
General tab.
AVI / Compression tab
This tab has all the video and audio compression controls.
One thing to remember in dealing with compression and data rate is output file
size. To minimize the size of your rendered projects, compress your files with the
best and the most recent compression algorithm possible.
Bit size is another way of saving your hard drive space. The bigger it is, the more
space you will need.
You will need to balance between compression, bit depth and quality of your video.
Experiment to preserve as much fidelity as possible using less memory space on
your storage.
• Be aware of the aspect ratio of the video files you are using and the
display aspect ratio of the intended playback screen for your videos. This
will help you determine which display aspect ratio to use in your projects.
• The aspect ratio is also important when dealing with moving paths in a
project. The moving path's aspect ratio should be similar to the aspect
ratio being used by the project.
Changing a project's properties clears the undo/redo history.
