I primarily edit my daughter's soccer games for the coaches to review with the kids. I have a static two-camera setup where one camera films the right side of the field, and the other films the left. There's about 20 degrees of overlap in the middle of the field.
I then import the two feeds into a multicam project where I cut back and forth from one side of the field to the other as the play progresses across the middle of the field. I then render this version as MPEG4
I then import the new MPEG4 file into a project where I do a lot of Pan and Zoom to follow the play around the field.
My problem is when the play goes across the middle. I need to move the frame from one side of the screen to the other on back-to-back frames keeping the current level of zoom. I do this by placing a keyframe on one frame, advance to the next frame, and drag the zoom over to the other side of the screen. However... This doesn't work if I only advance one frame. It doesn't place a new keyframe, but rather just changes the previous one. So.. my workaround has been to advance two frames, move the zoomed view, (it does create the second keyframe) then choose the new keyframe and move it back one frame. As you might imagine, when the play crosses the middle 60 to 80 times in a 70 minute match, this makes editing take a LOT longer.
Incidentally, on occasion, this DOES work where it will recognize and place the keyframe on the back-to-back frames. I don't know why, and it doesn't always do it, but it seems to be after the first 30 or so edits using the forward two, back one method.
Any suggestions? Is this a known issue?
