What is a 5MB WebM file useful for?
A 5 MB WebM at 720p is the standard size for testing VP9 video delivery pipelines and browser-based video player compatibility. Use it to test that your adaptive bitrate streaming generates correct WebM DASH manifests alongside HLS, to benchmark VP9 → H.264 transcoding throughput, and to verify that your media CDN correctly serves WebM with appropriate Content-Type and Content-Encoding headers.
