FrameForge is a focused, ad-friendly toolkit of 32 pro-grade calculators built for the moments you usually reach for a calculator app, a Reddit thread, or a $30/mo SaaS. Aspect ratio, FPS, LUFS, hook retention, pacing, bitrate — all client-side, no login, no upload.
Each tool is grouped by the workflow phase it actually helps with. Nothing here is "general" filler — every calculator was built to answer a question I've personally been stuck on while shipping videos.
Hook, title, story arc, chapter markers, B-roll planning.
Aspect ratio, safe zones, white balance, lighting, mic distance.
FPS, bitrate, color, EQ, ducking, jump cuts, pacing.
Platform presets, reframe crops, thumbnails, end screens.
Watch-time curve, length sweet spot, CTR, engagement.
Bookmark-able, deep-linkable, no scroll-jacking.
Most calculators online solve one variable and stop. These bundle the math with a "what does the number actually mean for your edit" interpretation panel.
Combine 7 weighted factors (visual motion, face on screen, text-on-screen, sound design, hook promise match, opening cut tempo, and B-roll density) into one 0–100 score with a recommendation tier.
Open tool →Generates sidechain-style dB values per platform, accounting for the platform's own normalization. Outputs an automation-ready curve you can paste into Premiere, Resolve, or FCPX.
Open tool →Instead of generic "warm vs cool" advice, you choose the target emotion (e.g. "lonely winter morning", "thrilling action sequence") and the tool outputs a Kelvin target, a tint shift, and the matching R/G/B grade values for Resolve/Premiere.
Open tool →Renders a per-platform safe-area overlay for 9:16, 1:1, and 4:5, including the actual caption strip used by TikTok/Instagram/Shorts, plus YouTube's end-screen widget zone, plus burned-in title safe.
Open tool →Most "free video tools" sites you find in search results are five pages of generic calculators, plastered with popups, stuffed with filler blog posts, and asking for your email before you can divide two numbers. None of that is needed for a calculator.
FrameForge ships the math, a written interpretation of what the result means, the limitations, and a few non-obvious knobs (e.g. "the platform normalizer changes the ducking math, not just the target loudness"). No login. No upload. No newsletter pop-up. No fake download buttons.
No framework, no bundler. The whole toolkit loads fast on a 4G phone.
Deep links per tool. Original explanations. No keyword stuffing.
Inputs, outputs, and copy all reflow cleanly on a 360 px screen.
Every tool ends with a "where this breaks down" paragraph.
Click any card on the toolkit page. The page jumps to that tool's section via an in-page anchor.
Type your actual values. Sensible defaults are pre-filled so you can copy-paste your workflow.
Each tool returns the math and a written recommendation. Don't skip the limits section.
For the math side (bitrate, FPS conversion, LUFS targets, aspect ratio math) — yes, they're the same formulas used in commercial tools. For the editorial recommendations ("will this hook work?") — they're an opinionated heuristic, not a guarantee. Treat the score as a second opinion, not the verdict.

Uploading a video to a random site is a privacy risk, costs real storage money, and is exactly the kind of "value exchange" that pushes creators away from indie tool sites. Every tool here works with numbers, not files. Your source files stay on your machine.
Vendor docs target the safe, default, lowest-common-denominator case. The numbers here are tuned for one-person creator workflows where you're shooting, editing, and publishing the same week. Always sanity-check against your platform's official docs if you're publishing for an enterprise brand.
Skip the spreadsheet. Skip the "I'll figure it out in the edit." Pick a calculator, get a number, ship the video.
