Hi
".... I'm trying to find out if I can change the aspect ratio for individual clips. Right now I am using still photos with some video.However if I change the aspect ratio on one clip, it changes it for all clips. ...."
This is perfectly possible as Borate describes. Obviously if your timeline consists of separate clips/images the effect you are seeing should not happen.
But my question is..Are you wanting to get all the clips/images to the same AR (e.g. 16:9 ) because they are different to start with and you want to get rid of black borders that are inevitably present?
If this is the case then it is quite easy but it means that some images/clips will have to be cropped down the required AR and then scaled up to fit in the VP frame. For those clips/images some of the area will be lost. If you still want to see the whole clip area and not crop then the only way is to stretch it...probably not the best option.
If this is the case and you don't want to stretch anything but have all the timeline the same AR do this for each clip/image......
Move the Red cursor line to the start of the clip/image
Click the FX box at the start of the clip
In the Effects window click the large green + at the top left.
Select the Zoom effect. This places a rectangle on the Clip preview screen.
Click the down button on the Restraint option
Select the required AR from the drop down list. (e.g.16:9
Adjust the size and position of the rectangle in the clip preview window so as to outline the area of interest. The rectangle will remain 16:9. If the clip is already 16:9 then nothing need to be altered; it will appear in full frame.
Close the effects window. This effect will only affect the clip in question
Repeat for the next Clip/image
When played now all the clips treated will be full frame images with no black border or bars.
Selecting a different AR to 16:9 will introduce borders or bars. (but all clips can be made identical in this respect without any stretching.)
