newbie question – ‘burning hole’ transition effect ?

[Greg Janza]

Save yourself a ton of time and buy a pre-built effect from one of many online vendors.

Here’s one option:

thanks for the help gents, i think i’ve got this sorted. my only remaining question is, what i’ve done seems pretty complicated… i was wondering if there’s a better way to do it ?

here’s what i did :

on v4 i have an overlay.
on v3 i have a matte.
on v2 i have the 1st sequence i want to transition from, starting at 0.
on v1 i have the 2nd sequence i want to transition to, starting at about 10 seconds in.

the overlay is a burn transition effect that was filmed with chroma green on the outside of the burn hole, leaving black on the inside.

i made the matte from a copy of the overlay by putting a fast colour corrector on it to desaturate it and increase the contrast, so i could use it as a track matte for the footage on v2 [the opening sequence].

i put a track matte on v2, setting it to matte luma and using v3 as the matte.

i treated the overlay on v4 with an ultrakey keying out the chroma green, as well as a luma key, because without it, the black hole [the ‘burned’ part] covered the second sequence instead of revealing it.

that’s about it. so is there a better way to do this ?

Anyone remember this?

Hats off to you for doing all of that work but yes, there’s a much easier way. Purchase a pre-built transition that has alpha channel, drop it on your top layer and then change the blending mode of the transition layer.

well, that was money well spent. ☺

i am still trying to learn how all of this works, which is why i went through the exercise and didn’t go the easy route at first.

so when i use chroma keying [the ‘ultra-key’], is that converting a colour layer to an alpha layer, making it transparent ?

or maybe more to the point : why does the pre-built fire transition work so well [better than my attempt, anyway] ?

and am i wrong in thinking that the overlay i used [the one with the flame on a chroma-green background leaving a black hole] would really only be useful if you want to transition to black instead of to underlying footage ?
