I'm trying to put a single glint on a person's smile with a chime effect.

I have no problem creating the single glint I want, but when I'm trying to drag it to the person's mouth it drags a copy of the entire image with it.

Is there a way to turn the background off so that the glint acts more like an independent element with an alpha channel?

Thanks for any help.

Hi,

Because the Glint is a threshold based effect, you'll need to be a little creative to achieve the intended goal of adding the glint to the talents' smile.

With AE as host:

• create a new comp
• create a new black solid color layer (although the color of the layer isn't that important)
• select the paint tool
• double click the layer to open it in the paint mode
• set the brush to about 5 pixels and the color to white
• create a single paint spot somewhere in the layer - the middle works fine for this
• enable the paint on transparency option in the paint filter
• apply the Glint to this comp and set it up so that you have only one glint the size that you need
• precomp this composition (select move all attributes) - name it Glint
• place the "Glint" comp over the talent and drag it into position

I hope this helps.

Peter.

Hi Peter,

Sorry I didn't let you know what platform I was on.

Any chance you'd know how to accomplish this in avid?

I tried applying the BCC effect to a paint effect but it still kept affecting the image beneath.

Thanks

Hi Caton,

Well doing this in an Avid is a little more complex due to how that system handles alpha information.

• in photoshop create an image that has only a single white dot in the center and everything else transparent and save this as a tiff with alpha
• import this into the avid, make sure you include the alpha channel on the import
• once imported, drag this image onto a video track in the timeline above the clip with the talent
• apply the glint to the photoshop image
• in the title-matte controls group of the bcc glint filter, enable the apply to title-matte option
• you should now be able to reposition the glint image with the glint over the talent's smile

I hope this helps.

Peter.

Hi Peter, I found your info very helpful, still one prob:

Once the Tiff is in the Avid, I can repostion the dot within the effects editor to it's desired location. However once I apply the BCC Glint (Nested or Not), the dot returns to it's origonal position, when I try to re-position, the whole clip moves. (Back to square 1). When I step in to the nest the key symbol has been removed from the tiff, which means you can't move the alpha?

Any ideas would be much appreciated... Cheers

Ryan
