Iris transitions?

Hi. I am using PD13 on my Windows 10 on my Asus laptop. I am almost done with my 3-hour epic documentary, and the perfect finish would be an iris fadeout on one guy's face. You know, like in the old silent movies whare the screen goes black as a circle gets smaller and smaller on one character's face. I can't seem to find that kind of a transition in the transition room. Is there a place to find such a thing or a way to make it? Zorikh

Hi Zorikh

Here's a suggestion that you MAY or may not be able to utilise:

Go to TRANSITIONS and select ALPHA transitions. Select the STAR, right click MODIFY TEMPLATE. This transition zooms out, so we need to make it zoom in. Under the preview screen you will see a white progression line. Reverse this, ie "left side up" "right side down". The transition will now zoom in to centre as you require. Save and try it.

On inspection of the Alphas you made find one more suitable to you needs

I just tried that star and it works perfect as a reverse transition as instructed by the Shadowman. You did say that you want a circle one. I have it and it’s was created by a user and uploaded to the DZ. Here is the link: http://directorzone.cyberlink.com/detail/135982273 .

Let us know if these are satisfactory for your needs. laughing

You will need to place the transition that tomasc has suggested to the LEFT of the split on the timeline and, most likely, increase the duration to about 15 seconds.

Thanks! It works perfectly! I will be able top use this for a lot of things!

Next questions: Now that we have that, is there any way to set the location of the center of the circle? I mean, what if the subject I want to close in on is on the lower-fight of the screen, not the center. Is there a thing for that, or would htat be some sort of more sophisticated transition template or program? Zorikh

May be someone else will have an idea how to do what you require, but after many attempts I failed miserably.



My approach was to create a totally transparent file with Paint, import it into PD and use it it as a PIP. The plan was to have the transition placed on the transparent PIP clip, produced as an MP4, and thus it could be moved wherever required in the project. While this worked very well, to an extent*, with a PIP file that was not transparent, no matter how I tried the transition wouldn't work on a transparent file.



*The base file in the PIP MUST be transparent, otherwise when the transition is moved the base file moves too which clearly shows in the overall project.

Any ideas, people of the forum?

You can find pre-produced iris transitions on YouTube, and chroma out the background. Also try a Google Image search for iris wipe, etc. HP Envy Phoenix/4thGen i7-4770(4@3.4GHz~turbo>3.9)

Might be able to also create this sort of transition with initially creating a 'circular grey-scale' ... if that makes sense? Draw several circles (like in GIMP or some other drawing editor) and color each section 'more darkly'..... center circle to be black and the outer most one white. Then use a gaussian blur to blur all the variations of grey. Result is a smooth appearing white to black image - white at edges - black in center.

I was playing with this a while ago - forget if the transition goes from white to black or vice versa. But - you get the idea - and I think you can reverse the motion if needed.

But all that everyone else has mentioned - I'm sure that works - choose the method that is easiest for you to execute.

Your idea works if either the xp version of paint or paintnet is used. Unfortunately the newer versions of paint doesn't support the transparency you need.

Barry's idea is valid as I have downloaded and tried them in the past. The links were supplied on YT.

The Camera Iris transition from the DZ can be easily modified to accomplish what the OP want. Attached is a screen capture showing that transition modified to close the circle on the motorcycle rider in the upper left of the sample files. Same principle to go to the lower right of whatever person. See the attached screen recording on a previous sample project.

Let us know if this is helps. laughing

Hi all -

I'll post this anyway, even though tomasc has just made the same suggestion of cropping/shifting the image in Transition Designer.



Here's one I just modified from Joseph's original transition - http://directorzone.cyberlink.com/detail/124831203

Following Barry's green screen camera iris suggestion, I found this - https://www.youtube.com/watch?v=MtnKmxW70Ys

For some reason it has green & blue screen, which would require splitting the clip. I made it all green (attached)

Unfortunately, that idea lacks the flexibility of being able to shift the focus area.

Cheers - Tony

Good work tomasc & Tony. I'm sure the op will enjoy using that.

tomasc: I didn't realise there were different type of transparency. Thanks for your research.

Here you go Barry - a sort of summary of the above...

This hastily thrown together video shows:


  1. Iris transition

  2. Iris transition inverted

  3. Iris transitions set as postfix & prefix

  4. Chroma keyed green screen video

  5. Animated object - http://directorzone.cyberlink.com/detail/124831205

  6. Alpha channel video

Tony – You do produce the best camera shutter transitions. You outdid yourself this time around. The TF_Aperature Slow in PD Toots is 24.2 MB while your remarkably similar Camera Shutter is only 1.3 MB in size which is 18 times smaller and does the same job.
