What is a 5MB MP4 file useful for?
A 4-minute, 720p MP4 is suitable for testing video processing queue throughput and HLS segmentation. Use it to verify that 10-second HLS segments are generated correctly (~24 segments total), to benchmark thumbnail contact-sheet generation at regular frame intervals, and to test S3 multipart upload triggering at the 5 MB threshold. At this duration, transcoding to 480p completes in under 3 minutes in software — fast enough for automated integration tests.
What's inside this file?
Generated by ffmpeg. A 1,280 × 720 SMPTE colour-bar test pattern approximately 4 minutes long. H.264 Main profile at CRF 28. Audio: a 440 Hz sine tone, stereo, AAC-LC at 128 kbps. faststart moov. At this duration the mdat section contains approximately 7,200 video frames (at 30 fps) — a useful scale for testing frame-index traversal in media libraries.
