Transitions - can they be run in 'reverse'?

Why I ask is because I've recently gotten the idea to take 'sanpshots' and to use the worm-hole transition - AND a camera shutter sound, to simulate as if a camera was taking a picture during some video - having the snapshot image be of a duration for several seconds and then go back to 'live' footage.

It's not my idea - found it on a google search. Neat effect but I was hoping to enhance this by running the worm-hole in the normal direction (where it opens outward to the new image - from the center of frame to the periphery) - in other words can I reverse the transition so that the worm-hole would start at the periphery and close inward to the center of frame(into the new image frame)?

I was hoping that the same technique could be used on other transitions also - like the slow wipe downward could be reversed to a slow wipe upward, etc...

Thanks for any help

There's an almost identical post *here* with an effect that one of the members created, but you'd need to get PD13 to have the Transition Designer if you wanted to make something different.

For PD12, Pixelan makes several excellent and affordable transistions plug-ins, all of which can be reversed.

You can also try making the transition in the normal direction, then selecting and producing the clips + transition as a range. Put the produced clip on the timeline and use the Video in Reverse function from Power Tools, and you should have what you're looking for.

Sincerely do apologize for a repeat subject. Will look at your link and try what you propose. Thanks again for the response.

Hello CS2014.

I've just posted a suggestion on reversing transition effects but you need PD8 or upwards to create them.

Cheers!

The trick with using "Worm-Hole" or any other transition effect that has only one direction, is that you need to reverse the clip you intend to which you want to apply the effect, then put the transition at the end of it. If you intend to apply the effect to several clips, you need to apply them to the timeline in reverse order to what you would normally arrange them(like counting backwards), then reverse each clip in its position before adding the wanted transition effect, then "produce" the sequence. the newly produced sequence is then brought into the timeline, replacing the clips just used, that new sequence is then itself reversed, effectively restoring the forward motion of the clips but at the same time reversing the transition effect.

Hope that explanation is of some help. And yes, you need PD8 or later to achieve this effect.

I have gotten the wormhole and other transitions to run in reverse as I now have PD13. I've been working on trying to get a more accurately simulated shutter/iris closing effect using Transition designer. I am finding that trying to get a shutter vane picture made into an appropriately modeled grey-scale is my challenge at the moment. I'm trying to get the grey-scale oriented so that the black is on the tip of the shutter vane and the white is on the 'base' of the shutter vane.'

THis way - since the transition goes from black to white - I'd get a transition radiating out from the center (assuming that I have a closed shutter picture).

One thing I've noticed is that there is various shutter audio and some are longer duration than others. Depending on how fast I make the transition I am finding that I will use one audio or the other. It becomes a matter of positioning the audio correctly with the transition to sync them.

Thanks for the comments though.

Hi, CS2014. I'm curious about the Transition Designer! But in your comments about the shutter sound effect and its varying length, Pick the sound effect you want to use and make note of its length, then adjust your transition effect accordingly - 5 seconds audio = 5 seconds transition! Simple, really!

Cheers!

That is what it would seem like doesn't it? lol

But I've found two basic yet different sounding shutter audio sounds. One is quick , like a f32 shutter effect and the other a long, drawn out - almost like a two step process sort of shutter sound effect. Depending on which one I'd use, I will adjust if I'm going to use 6 - 8 frames of transition or - longer for that longer shutter audio effect.

Make any sense? When I stuck the beginning of that longer shutter audio, on to a 4 + 4 frame (shutter or wormhole closing in (4 frames) .. and then opening out again (4 more frames)) - it just didn't look 'as right' as when I used more like 8 or even 15 frames for both. THAT'S how long this slow shutter audio is .. that I have.

Transition designer is pretty neat - but I don't think it will do my 'ideal' shutter effect that I'd like to look into - one where you see shutter vanes closing in on the last video clip and opening up onto a new video clip or onto a jpeg or png file.

I'm starting to think about looking into the PIP effects to see if I can get something to work there.

Hi, CS2014!

The shutter speeds you talk about are very quick, less than 1 second(just a few frames each). I have, of late, started a practice of editing my videos down to exact seconds, cutting out frames beyond a full second, for example, a clip I've shot could run for 2 minutes, 35 seconds and 12 frames, it's those 12 frames that find their way to the "cutting room floor", so-to-speak. I edit my videos to run for an exact number of minutes and seconds so I can work out a bit better how much content I can squeeze onto a DVD.

Cheers!

Neil.
