Change the opacity for thousands of video clips.
My friend told me about this site today and I hope that I find my answer here ASAP.
I’m making a short video with 100 clips which is about 3 seconds each. Each clips contain face of women and I’m planning to overlap them all together and change the transparency so you get the average face of women from the 100 different clip. To do that, I have created 100 layers(!!). On the first layer, I copied and pasted the original clip for 100 times. On the second layer, I copied and pasted for 99 times and it keep goes down until the last layer with 1 video clip with the no repitition.
The problem is that I have to click each video clip and change the opacity. For example, I double-click the first clip on the first layer and type in 100 for opacity and click the second clip on the first layer and type in 99..98..97. For the second layer, I do the same thing except I start from 99%.
Is there anyway that I select all the clips within one layer and set up some kind of trick so the opacity goes down automatically without me typing in each number?
One more question.
Since I have to make an average(which would be blurred) face, I have to be very meticulous about the placement. In other word, I have to put eyes, nose, and mouth in certain spot so it would overlap with others. Otherwise, the final image would look like a monster instead of face of human. But it’s really hard for me to change the placement after copy and paste over 1000 clips already! That means if something doesn’t match, I have to go back and change each clip’s position.Is there any link tool in the Final Cutpro program like the one in Adobe Photoshop when you link the layers together, all the layers move around together as if they were one piece? The main difference is that in the photoshop, you link the different layers but I want to move around the all the clips at once within one layer.
I’m not sure if I described all of this problems right but someone please help me out!
I have to finish this video by tomorrow and I’m not even half way done! I would appreciate your help! THANK YOU VERY MUCH!!!! -

First this whole thing would be better achived in After Effects. But since that is probally not an option- my thoughts. If you exported each layer as its own movie you could easiy keyframe the opacity for each layer movie FOR 100-0. mabey I’m confused by what you want to do (Q2) but why cant you click drag around everything you want to position?

probably to late for your due date tomorrow, but maybe on the next project see if this plug-in might help:

Not sure if it might do what you need, but you could email them and see if the node based software is something that can manipulate your clips in the way you need.

I know. I shold learn Adobe After Effects. My friend suggested me on that but I guess I will finish this project with final cut pro first. Maybe I’ll make each layer into its own movie but how do I control the keyframe? I know how to insert it but I have no idea what it is for.

If I have understood you correctly, you can use the “Paste Attributes” function. Start with the last clip in your sequence, adjust opacity, position and scale for each layer until satisfied. Then copy the clip on the first layer, select all clips on the track (TT on your keyboard) and Paste Attributes (alt-V). Repeat for the other layers.
If you have Photoshop, you might consider doing the layering there and import the file to FCP.
Another thing: If your sequence starts with one clip with 100% opacity, then the next with two layers, the top having 99% opacity, it will look like a cut for the first few clips…Is that what you want? -
Irene,
I think that this may help:
Change the opacity of the first clip
Apple-C that clip to copy it
Lasso all the other clips to select them
Alt-V to bring up the Paste Attributes menu
Select Opacity (and any other attribute you wish to paste – you could use this to paste basic motion data enabling you to move multiple layers a la photoshop)
Paste – et voila!All this can be done via menus as well as short cuts.
HTH,
Jason
