Find the simplified ratio of a frame and the proportional height for a new width. This calculator helps plan dimensions; it does not crop, resize or upload your video.

tools

Estimate media payload size from duration, average video bitrate and audio bitrate. Results include decimal megabytes and binary mebibytes so the units remain clear.

tools

Estimate the average video bitrate available inside a chosen file-size budget after allowing for audio. Enter a conservative media budget, because container overhead is not included.

Build an editable production estimate from preparation, capture, editing and revision hours, a blended hourly rate, fixed costs and contingency. Every value is your assumption, not an agency quote.
