Interactive tools

Free calculators for video engineering.

Four interactive tools from Fora Soft engineers — video bitrate, storage cost, codec ROI, and a same-VMAF codec comparison. Plug in your numbers and get the answer a senior engineer would put in a deck.

The tools

Pick a number to work out.

Each tool pairs a live calculator with a full explainer and a downloadable cheat sheet — built for product managers, founders and ops, no engineering degree required.

01

Video Bitrate Calculator

Uncompressed and shipped bitrate, file size, and S3 storage cost for any resolution, fps, codec and duration — with a pipe-fit check against 2026 network medians.

Open the tool

02

Video Storage Cost Calculator

Source, mezzanine and rendition bytes and the monthly cloud invoice across S3, R2, B2, Wasabi and the cold tiers, plus an AV1 / HEVC migration break-even.

Open the tool

03

Codec ROI Calculator: H.264 to AV1

CDN egress and storage savings, one-off encoding cost, and the break-even month for an H.264-to-AV1 migration, with an AV1 device-reach slider.

Open the tool

04

Visual Codec Comparison

The bitrate H.264, H.265 and AV1 each need at the same VMAF, by content class, with a frame-by-frame artifact preview and runnable FFmpeg recipes.
