A sigmoid function is useful for lots of graphics applications, it’s yer classic ease-out, ease-in curve for animation, and its a film-look response curve for colour.
From the “Posted on the Blog so I Can Remember it Next Time” department: A useful expression for making things symmetrical.
This is a script I should have written years ago. It’s fairly simple; it duplicates the selected layer in a comp, but unlike the built-in duplicate function it creates a new source for the layer in the project, allowing the copy and the original to be independent of each other.
You can use text layers in After Effects as expression editors which means, among other things that a whole lot of layers can use the same expression. This has some big advantages: expressions update as you type, which gives you instant feedback. You can see and edit your expression right in the composition viewer, without … Continue reading Using text layers as expression editors in After Effects
Because of Lightwave’s rather broken undo system you need to save lots of incremental backups when you’re working on a scene. Mike Green kindly provides a script that makes a numbered backup of your file, so that your current copy keeps the same name. Drawing on his open source (yay!) script I’ve changed it so … Continue reading Save-n-Zip: automagic backups for Lightwave3D
I was doing some research on screen and camera resolutions for some reason a while ago and came up with this illustration, listing all the digital video resolutions I could find in use as of 2016. PDF version here. Let me know about any errors or omissions.
Building ffmpeg from source on Windows is a royal pain. For those who came in late, ffmpeg is the best reason for a video nerd to learn the command line.
The lookAt() function in After Effects’ expression language doesn’t work for 2D. If you’re trying to use it to align the layer to look at a given point, without having to remember all the trigonometry you learned in school, it turns out you should have spent less time smoking behind the shelter sheds, because this is … Continue reading LookAtMe! A 2D lookAt() function in AE Expressions
There’s no shortcut for creating a new folder if you have files selected in Windows Explorer, so I made one with AutoHotkey. I always find using AHK a bit kludgy if it relies on sending keystrokes; there’s too much that can go wrong. But anyway, here ’tis.
