WebM: Great for Chrome, Terrible for Everything Else
WebM is Google's baby — tiny files, fast streaming, perfect for web. But try sending a WebM screen recording to your client. "Can't open file" is not the response you want. This WebM to MP4 converter fixes that instantly.
I record tutorials with OBS in WebM format (smaller files). But for sharing? Always convert to MP4. Last week's 500MB WebM tutorial became a 600MB MP4 — slightly bigger, but now it plays on phones, uploads to Vimeo, and imports into Premiere Pro. Worth it.
