VHS Glitch Tutorial Pt. 2: Chroma Split, Wave Expressions, Procedural Value Manipulation


Part 2, following on from the last part. I’d made some small tweaks before starting record on this, but it shouldn’t matter as I’m intending for this to be more of a general guide with some tips/tricks and theory, rather than a step-by-step to be followed.

There’s a few random cuts here and there, some labelled, some not. This is usually where I started going down a path that didn’t work and I just deleted it and reverted back to where I started. Give me a shout if there’s anything confusing in there! Will post a follow up in the weeks to come, getting some more design elements in there and more polish on the look.
