What is a 5MB MKV file useful for?
A 5 MB MKV is a realistic size for a short OBS game-capture clip or a screen recording of a software demo. Use it to test your media processing queue's MKV handling at a size that exercises multi-cluster parsing, to verify that your ffprobe duration extraction works on Matroska containers with multiple clusters, and to benchmark MKV-to-MP4 remux throughput as a step in your user video processing pipeline.
What's inside this file?
Generated by ffmpeg. A 1,280 × 720 SMPTE colour-bar test pattern approximately 3.5 minutes long. H.264 Main profile at CRF 28. Audio: a 440 Hz sine tone, stereo, AAC-LC at 128 kbps. Matroska container. At this duration the file contains multiple Matroska Clusters (each Cluster holds approximately 1–2 seconds of interleaved audio/video blocks), exercising cluster-aware seek implementations in media players and parsers.
