The transparency of the EPS layer can be adjusted with the TRANSPARENCY property.

When you animate this property and export the video with transparency you have an animated alpha channel.

Is this what you are looking for?

Sorry, I can not explain well,
I say that even if there is a background or other opaque layers, have a layer that creates an alpha channel even though behind it has other layers. As in the image I attached.
I know it can be done directly in BluffTitler, but can you do it in editing?
If I put a transparent EPS it disappears and that's enough, so I see the layer behind it.
Can I insert a video from the edit software on this hole? Or I can color it green and make a chromakey in editing, but it's not the same thing.
Thanks, sorry for the bad explanation.

if there was a "key" signal, the editing program could pass the video at that point

place 1st pic on pos 0 0 500 (background pic)
place 2nd pic on pos 0 0 486
place solid text on pos 0 0 480 and set transparency to 0.99

Franco, do you mean that you would like to invert the alpha channel?

And have you already experimented with the Special\Masked effect?

michiel, 7 years ago

Works perfectly with BluffTitler

vincent, 7 years ago

what effects did you apply?
I know the audio effect, I say for the key.
Thank You, Vincent.

I tried Vincent, but I did not understand why I did not succeed, so please get me the file?

Franco Aversa, 7 years ago

Franco, here is a simple file. Does it work for you ?
IMPORTANT : Z position of Rond.EPS (layer #3) must be very close of the Z position of picture layer #5 .

your file works, I tried to redo it, the key works but when I move the circle turns off and turns on.
Thanks so much.
Now I'll do some tests

Franco, i had the problem too, it seems there is a great sensitivity with the EPS Z position, maybe you must adjust a little the Z position along the timeline adding some position keys and/or modifying some existing.
To tell the truth, i don't know why it works, is it a bug ?! i noticed it doesn't work any more when changing eps depth bias to 100 or -100
But it seems working a little better with depth bias = -100 for layer 5 (brick wall)

I'm happy if it works for you, so it's enough for me as thanking.
You can play with sketch and text layers too.

vincent, 7 years ago

thanks again, that was what I was looking for.
I do not have to do this with an external program!

Franco Aversa, 7 years ago

@Vincent

if you remove the background image, the remaining black hole leaves the alpha key, so it also works on the external video editing program !!! WOW

Franco Aversa, 7 years ago

Super, Franco, our BluffTitler is G R E A T ! ! ! ?

vincent, 7 years ago

Thanks for showing this.

@Franco,
Removing the background image leaving black and exporting as AVI (compressed) with transparency makes a huge file of almost 3GB using Vincent's file.

Exporting to MP4 has a black background, but using a chromakey of black doesn't work because any black in the overlay image will become transparent in the video editor.

I changed the background picture to white.png, made it green and increased the size to cover the screen. Now I have a green screen effect. I exported to MP4 and gave it a chromakey green in the video editor. Worked perfectly and the file size was now only 2.4MB. Of course, if the BT images have green in them, there could be a problem.

I'm learning.

The trick is effectively to give the background a unique color in order to key it in a chroma process.
