Developer FAQ
Practical answers for technical video.
Why use UVE instead of the site speed menu?
Many tutorial and conference players offer limited speed options. UVE adds fine steps, keyboard control, templates, and per-site memory across compatible HTML5 players.
Can I control speed while coding?
Yes. Keyboard shortcuts let you adjust speed and volume without leaving the page. You can also save a reusable tutorial template.
Does UVE help with quiet conference recordings?
Compatible HTML5 video can be boosted above normal player volume — up to 200% in Free and 600% in Pro.
Which sites can developers use it on?
Any site with a compatible HTML5 video or audio player, including many tutorial platforms and YouTube. DRM or custom players may restrict control.
