Video Multi Tool

Video Multi Tool provides domain-focused calculations for video engineers and editors. It accepts inputs such as target duration, video bitrate, audio bitrate, container format, and optional constraints (max file size, target quality index). It then computes derived outputs including total file size, required video and audio bitrates to meet a target size, and a practical estimate of encoding timelines given a hardware profile. It can work with multiple containers and flag incompatibilities between chosen settings and target constraints.
Conceptually, the tool relies on the bitrate formula and supports both constant bitrate (CBR) and variable bitrate (VBR) modeling, with optional per-track audio allocations and two-pass estimates. It includes rounding considerations, optional audio channels, and container overhead adjustments to produce realistic numbers. It provides both raw numeric outputs and recommended presets suitable for insertion into encoders or pipeline configurations. It does not perform encoding; instead, it offers auditable math, clear assumptions, and a mechanism to compare scenarios side-by-side.
Audience and use cases: video producers planning budgets, editors evaluating archival storage, and streaming ops teams scheduling transcoding workloads. Unique differentiators: simplicity, transparency, and extensibility; supports scenario comparisons and cross-checks with alternative bitrates. Example: for a 10-minute video at 5 Mbps video and 192 kbps audio, the tool estimates a base size and explores containers to meet distribution constraints.
