Total Video File Size Calculator
Quickly estimate how large a video file will be based on its bitrate and duration.
Actual size may vary with codecs and metadata overhead.
Examples
- 5 Mbps for 10 min ⇒ 375 MB
- 8 Mbps for 60 min ⇒ 3600 MB
FAQ
Does this include audio?
The bitrate should represent the combined video and audio streams.
How do I convert MB to GB?
Divide the result by 1024.
What about variable bitrate?
Use the average bitrate for variable encodes.
Additional Information
- 1 byte = 8 bits; calculation assumes constant bitrate.
- Container overhead and metadata may slightly increase actual file size.
