Tools for the practical questions
VideoTools is being built for creators who need to plan a file, choose a bitrate, estimate card capacity, or set expectations for an upload. The goal is to answer those questions quickly without asking for an account or sending a media file to a server.
How calculations work
Calculator inputs are processed in your browser. The formulas and unit assumptions are shown on each tool page so you can check and adapt an estimate.
Actual encodes and uploads vary with codec settings, variable bitrate, metadata, networks, and device behavior. Treat each result as a planning estimate.
