Bitrate from Target Size
Formula
File size = (bitrate × duration × 60) / 8. Bitrate = (file size × 8) / (duration × 60). All in consistent units.
Frequently Asked Questions
What bitrate should I use for 1080p video?
For 1080p video, a bitrate of 8-12 Mbps is recommended for good quality. Streaming platforms typically use 4-8 Mbps.
How is file size calculated from bitrate?
File size (bytes) = bitrate (bits/sec) × duration (sec) / 8. Remember: 1 byte = 8 bits.
