Render to video update: now with audio track and branding support! — Keysight Steam update #396078

Hey folks! Feels a bit weird to post another update announcement so soon after the previous one but some HUGE progress has been made and released on the beta branch! (Still Windows only for now, Mac coming soon, I promise!) Render to video can now export with an audio file! This requires you to have an audio file you want to downmix (Keysight will not generate audio for you, and never will). But by specifying an audio file, you can now render an entire "functional" video in one go and slap it straight on Youtube or anywhere, no editing required! In fact, while you're at it... Branding and fading animation support in video renders! Want to show a splash image, watermark or end-card in your videos? Now you can! I've included a "presskit" of Keysight images to act as default branding and give a template, but these images are (of course) user-configurable. You have full control over fade-in/...
