Hi
The zoom shown in the video for V3.01 is not a true zoom and shows simply the whole image or clip reducing or increasing in size with the production of black borders around a smaller or larger image.
The correct zoom effect is the one provided with V2.41 in which the whole screen remains filled with a varying portion of the image,(ie magnified,) the aspect ratio remaining the same, (but selectable.) There are no black borders. It is also much easier to use and one can see at a glance how much of the image is zoomed into and also its position at the start and finish.
The effects shown in the clip are more suited to an overlay image or fancy titles but are effective. However, in the absence of a "proper zoom" (I could't find a way to get one to work,) I would suggest that V3.x retain the original zoom effect along with the ability to select aspect ratios but at the same time also implement the new version.
