Ping your content delivery network (CloudFront, Cloudflare, Fastly) with a HEAD request to the 1GB file. Check the X-Cache header. Then download 500MB worth (using Range: bytes=0-524288000) to verify partial caching. ffmpeg -i original

Use testfile.org. Their algorithm generates precise files to the byte. Alternatively, use the Linux truncate command: truncate -s 1G exact-1gb.mp4 (fills with null bytes – won't play, but valid for storage tests). Then check size; re-encode with different bitrate if needed

Open a terminal and use the “null” or “testsrc” source. This creates a synthetic pattern video.

ffmpeg -f lavfi -i testsrc=size=1920x1080:rate=30 \

 -c:v libx264 -b:v 10M -t 900 -c:a aac \
