reverse circle transition?

trying to achieve 'looney tunes' closer, but can't see any way to reverse the direction of the default iris wipe. i have searched but don't seem to find any reference.

in most nle's i've used previously it's generally a 'reverse' direction button?

thanks in advance

i did find this thread -
viewtopic.php?f=21&t=68414
but reversing graph doesn't do anything - or perhaps i'm not understanding the directions?

You can reverse the direction using the curve editor, but you end up with a large black dot that shrinks. Giving you a reveal instead of a closer. In addition to reversing direction, the effect needs to be inverted.

You could pull it off in the color page with a Circular Power window and keyframes though.

That was the only solution I could think of, too. Or doing the wipe and creating a compound clip of just that effect, then reversing the speed in the timeline (which is a bit clumsy).

thanks gents, appreciated.

it all sounds rather complicated just to achieve a simple 'reverse' of a wipe.

i think i'll work out some other closer - might well be a better idea since many viewers are probably too young to remember looney tunes anyway ;-)

but a reverse button might well be a simple idea worth implementing?

I was the OP on that other post you found. If you know how to get to the graph editor (for the transition effect), then reverse the "polarity" of the graph, make it go down from left to right instead of up. Make sure the transition effect is applied to the layer of black video that's over top your footage. The transition is Not applied to the footage itself.

Does this help?

hi ben,

thanks for getting back. i followed your instructions the first time around, and yes, they work changing the direction perfectly, but what i'm after is inverting the effect, ie, the background becomes foreground - just like looney tunes ending.

hope that makes sense?

anyway, thanks for the reverse info.

ok, sorted!!!

top video track tweety-pie, black gen media below, use iris wipe on tweety-pie, and reverse direction as per your instructions, cue looney tunes music ;-)

Ah, this is good to know. I would love to see them have a "Reverse" checkbox in all of the wipe transitions.

couldn't agree more... along with an 'invert' ie. bkg<>foreground

Only solution I can think of is to reverse both clips, join, transition, aggregate the trio, and then reverse it back forward.

Yes, a long way around the barn.

For anyone still looking to reverse stock transitions (like Looney Tunes circle close / closing black bars), this worked for me:

1. Add Solid Color generator from Effects library above your timeline clip
2. Apply normal video transition to Solid Color clip
3. Double click transition to reveal more, and click keyframe editor button (on right side of transition clip)
4. Reverse slope of transition gradient, starting at 1 and ending at 0.

Hope this helps some struggling beginner DR editors our there.
