Estimate Your Video File Size
Before you export that long video, it's helpful to know how large the final file will be. This calculator estimates the size of a video file based on its duration and the bitrates of its video and audio tracks. It's perfect for managing storage space and planning uploads.
Frequently Asked Questions
What is video compression?
Video compression is the process of reducing the total number of bits needed to represent a video. This is done by removing redundant data. The bitrate directly controls the level of compression: a lower bitrate means more compression and a smaller file size, but potentially lower quality.
Where do I find the bitrate of a video?
You can often find bitrate information in your video editing or encoding software (like Adobe Premiere, DaVinci Resolve, or HandBrake) when you export a video. For existing files, media players like VLC can show you this information under "Codec Details" or "Media Information".
