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).
Don't just test with high-bitrate files. Include low-bitrate 1GB files to test how systems handle long-duration, low-bandwidth scenarios.
