WebM tips
🌐
WebM (VP9) is the web-native format — it tends to be smaller than H.264 MP4 at the same quality, ideal for self-hosted web video.
⚖️
Pair a WebM source with an MP4 fallback in your <video> tag so every browser, including iOS Safari, has something to play.
⏳
VP9 encodes slowly in the browser. For long HD clips, expect a wait — it's doing real encoding on your CPU.
🔒
Encoding happens locally, so unreleased web assets never leave your machine.
