About FrameKit Studio

FrameKit Studio is an independent post-production and video engineering toolkit built for video editors, finishing colorists, assistant editors, and creators who need accurate calculations and ready-to-run command lines without uploading confidential media to third-party servers.

Why Client-Side Processing Matters

Many online video and subtitle utilities require uploading source clips or transcripts to a remote cloud queue before returning a result. That workflow introduces network bottlenecks, file-size caps, and privacy risks when handling pre-release footage. Every calculator, subtitle parser, safe-zone canvas, and FFmpeg command builder on FrameKit Studio runs inside your browser tab using standard JavaScript and on-demand WebAssembly (@ffmpeg/ffmpeg via jsDelivr CDN).

Documentation & Formula Transparency

Each of our 12 utilities is paired with the exact mathematical formulas, bit-versus-byte conversion factors, macroblock alignment rules, and parameter reference tables used to produce its output. You can inspect and verify every equation directly below the interactive workspace.
