Black & white to Color gradually from centre out

Videot wrote on 2/18/2005, 1:17 AM

How would I do a transition from 2 copys of the same freeeze frame and have the first clip be black & white & the second in color. I wanted a sort of bard door effect so that the centre of the screen would slowly appear on color & gradually widen both to the left & right until the entire view is color. I know that the first event will have the black & white filter on it . If I were to do it as using a transition like the barn door you end up getting the same vision on the screen twice & this wasn't what I was hoping to achieve.

Insert a new video top track with a solid white media generator. Make that track a parent to track 2 (b/w event). Set the new track 1 compositing mode as Multiply (Mask). Drag the top right corner of track 1 white media to add a fade out. Drag a barn door transition (Vert Out No Border or add Feather to soften edges) up to that fade out and drop it there. It now becomes a barn door transition on the fade out area revealing the color event on track 3. Adjust the timing as needed by dragging the length of the transition bar in the track 1 event. Add a Split to track 1 and 2 if needed to make it happen sooner with a certain speed.

I can't imagine what the problem is. I'd put the same event on the timeline twice, add the B&W filter to the first, overlap them, and drop the barn door transition on the overlap. That should be all that is necessary. There shouldn't be any need for additional tracks or masks.

Did you try it? A dissolve works but a barn dorr will not. It will always produce two images during the transition.

A Barn door is a slide rather than a wipe.

Best way I know is with the Pixelan Spicemaster, but within Vegas, a Linear wipe is a starting place, but that's unidirectional. Maybe try a Cross Effect

Why not use a cookie cutter with a feather on it? This way you can target the specific area you want the transition to begin. No dual images, feathered will blend the edges.
Pixelan is definitely a better choice to do this with, but it also costs $$

Could you just use a mask, and then use track pan/crop to change its size?

another free and easy way in addition to my first suggestion is to use the free plugin called SMLuminance.
http://www.endor.demon.co.uk/

then create a gradient pic of black to white to black, side to side, to use for the transition. you can make the pic with vegas media generator quite easily and save it. you can use the plugin for either direction of wipe.
or spend money on another app like pixelan and do what vegas can already do.

I just tried an easy method.
Put black and white on top track, colour on track two. Use the Iris transition on the top track with a feather set to .5 or whatever suits.
Heck you can even have rectangle or oval.
And you can keyframe the position.
