Tip: Using a Grade Layer to apply Speed to Multiple Layers

I have a Comp (#1) with several layers in it. That comp is embedded in another Main Comp (#2) and I wanted to change the speed it runs at in that comp.

So, I know I need to add the Speed Effect to the Comp (#1) that's going to be embedded, rather than in the actual Main Comp (#2), but I knew I would need to adjust it a few times to get the timing correct and didn't want to have to do that to all the different layers of video in Comp (#1) until I got it right.

The solution was to drop a Grade Layer on top of the other layers in Comp (#1), apply the Speed parameter to that layer, set it to 0.5 to test with and all the layers slowed down together, both in the Comp (#1) itself, as well as in the Main Comp (#2)

The only thing that you need to be aware of is: when playing back the Comp (#1) with speed applied, any Keyframes are in the original positions, not the slowed down, or sped up positions, so they'll appear out of sync with the video when it plays. Turning off the Grade Layer's Speed Effect will allow you to make changes to those properly, then turning it back on again will make it run at the new speed again.

Well, it was news to me, anyway... :)

    Nope, that's a good trick. Never occurred to me to put speed on a grade layer.

    @Triem23 And this was the result. I wanted the blobs to run through their cycles at different speeds.


    Might do a simple Tutorial for it, as the AE one I watched took some translating. It also took some serious slimming down after getting it working, with a single "double" ink blob, not the 15+ the tutorial was using.

    I pruned 75% of it out and it still worked. It's apparently much easier to do this in Hitfilm than AE. :)

  • Absolutely love the effect.

    @Palacono Nicely done! I'm pretty sure I've seen the tutorial you're talking about. I watched it long to decide to move on to trying something else because there was a deadline ;)

    @NormanPCN thanks. See the text section? That's the same blobs as used elsewhere, scaled down. One double blob, with a second version at 50% transparency in the same layer, with slightly different timing and angle. That's it. :)

    The 50% transparency bloblet let's the image bleed through to what's below, which gives you the neat side effect/bonus that you get the main image and the 'Cartoon Effect' version combined around the "How to Make Kylo Ren'" text and 'Watch the Tutorials' part of the screen for a third 'look'. So there is Cartoon, half-and-half and Full image.

    Text layer uses some transparency and a Burn Effect I think, but basically, Demult, Multiply and Set Matte are responsible for all of this. :)

    Yup. That's a good Ink Matte wipe.

    You're right, there are many things it's easier to set up in Hitfilm than AE. (Although, yes, AE still has many advantages.)

    @Aladdin4d It was this Tutorial:


    And here was the image I created from it after I'd followed it most of the way, then simplified it down to a lot less blobs.

    But after I Hitfilmed' it in the video above, I simplified it even further just to see how far I could go. :)

    You don't even need a video of an ink blob, just draw one and have it scale up on its own timeline, and slap a few on a comp and use that. The project I used for the video above has multiple layer and comps etc., but for a simple couple of blobs from an image, how simple is this timeline compared to the AE one?

    That's only the Colour image, no Cartoon or Text, but it's pretty simple to add two more layers.

    @Palacono. Yep that's the one! If I remember right because of being under the gun I ended up getting a Matte Magic module from Digital Juice and it was just before they changed to a subscription model

  • @Palacono - Thanks for the tip! Now when someone asks how to speed up a video we'll have another option to offer.

    @Aladdin4d ; Matte Magic looks like it has some nice stuff and now I know what I'm doing, I can pretty much drag anything I like onto a video, Demult it and Set Matte and Bingo!

    There are loads of free Animated Transitions all over YouTube, but I had no idea what to do with them before, as I didn't know what the Hitfilm equivalent of the "Track Matte Key" all the AE Tutorials talk about was.

    Finally starting to get the hang of this now. ;)

    Tried it with video on my "See if I can simulate 3D tracking in 2D entirely with Hitfilm 3 Express without having to buy AE after all" Experiment. Works a treat. :)
