Again, I think it’s pretty rare that anyone would stumble into these issues–and the only reason I point it out is because it’s actually happened to me! I was exporting to a QuickTime file (can’t recall the codec right now) and had alpha enabled without even thinking about it. That said, perhaps a preference setting or a sequence setting that would make the base layer opaque color, would make a good feature request. But this is not how I’ve seen people work – they just apply Dip to Black, and then wonder why it doesn’t work as it should.
And I agree that you can adjust Dip to Black end or start point, which would be the equivalent, even more “kosher” than cross-fade from alpha. Of course I agree that the “most proper” way to do it would be to use black video either above, or even easier – as a base layer underneath all clips.
Perhaps it was a wrong assumption, and I should have covered that as well. I was considering mentioning that in the article, since I’m obviously familiar with the way cross-fade works, but then I thought to myself that if you ARE fading from black or to black, you are operating on the whole picture, and would most likely not want to export to a codec with alpha, and considered to be a little bit over the top. I certainly don’t do this… but you canįunny you should raise the alpha issue. All you have to do is set the Start point to 50 for a fade in, and the End point to 50 for a fade out. Since it’s usually common practice to have a black leader at the beginning or tail at the end of a sequence, you can accomplish this easily with one clip.Īnd technically, you CAN create a fade to/from black using Dip to Black. Simply create the synthetic, add a short piece at the beginning or end of your sequence, and apply a single-sided cross dissolve at the appropriate place on the black video. What I advocate is using a Black Video synthetic clip to create a fade in or fade out. Most of the time, it’s not an issue, but I’ve seen it before… As described above, you can probably see why this would be the case. While in most cases you can achieve the result you want–a fade to or from black–using a cross dissolve as you’ve outlined, this can cause problems when you export to a format/codec that supports alpha/transparency. A Premiere Pro sequence is 100% alpha when the frame dimensions are not completely filled with 100% opaque clips you can see this by changing the Display Mode to Alpha and placing a clip that has smaller dimensions than the sequence into the sequence. If you use a cross dissolve on a base video layer to fade in or out to black, you’re actually dissolving to or from transparency. Strictly speaking, a Fade To/From Black is exactly that: a fade TO or FROM black. However, I don’t agree with you on using a cross dissolve as a single-side transition to achieve a fade in or fade out. I understand your point on transitions, particularly Dips and Fades.
