What is a 1MB WebM file useful for?
A 1 MB WebM at 720p demonstrates VP9's compression efficiency advantage — at the same quality level as H.264, VP9 delivers approximately 40% more duration per megabyte. Use it to benchmark WebM upload processing, to test that your media pipeline handles Opus audio (which uses 48 kHz rather than the 44.1 kHz standard used by MP3 and AAC), and to verify that VP9 content is correctly identified for transcoding to H.264 before Safari delivery.
What's inside this file?
Generated by ffmpeg. A 1,280 × 720 SMPTE colour-bar test pattern approximately 60 seconds long. VP9 at CRF 33. Audio: a 440 Hz sine tone, stereo, Opus at 128 kbps, 48 kHz. WebM container. Opus at 48 kHz is the native sample rate — Opus always resamples audio to 48 kHz internally regardless of input sample rate.
