for the sequence is larger or smaller than the current frame size, it must be resized
or cropped.
HDV
Abbreviation for High Definition Video. It is the video recording format that allows
for high data compression, and in turn allows for higher picture resolutions. HDV
can go up to 1920 x 1080 in resolution.
HiColor

Allows you to view the entire project without rendering. It instantly plays all the
