Remove Tactical Mode slow-motion from Final Fantasy VII Rebirth combat captures so the whole fight plays at uniform real-time speed.

FFVII Realtime

Remove Tactical Mode slow-motion from Final Fantasy VII Rebirth combat captures so the whole fight plays at uniform real-time speed.

The clip first plays as captured — Aerith picking a command in Tactical Mode slow-motion — then, after the flash, the same moment at real-time speed with the spell firing off. (higher-quality MP4)

In Rebirth, opening the Tactical Mode command menu drops the game into heavy slow-motion (apparently 100x slower than real-time) while you pick your actions. It's great to play, but these pauses, especially long ones, aren't much fun to watch in a recording. FFVII Realtime automatically finds those slow-motion segments and speeds only them back up, leaving the rest of the fight untouched, so the whole thing flows at one natural pace.

Example: a 1:55:00 capture became ~1:09:00 of continuous, full-speed combat — around 570 Tactical Mode segments (~47 minutes of slow-motion) detected and sped up, fully audio-synced.

How it works (short version)

1. Detect — a computer-vision pass (OpenCV) scans every frame and recognizes Tactical Mode two ways: the on-screen L2/R2 button prompts at their fixed positions, and the "Tactical Mode" header text above the command menu. Both are made robust to bright/gray/busy backgrounds by combining color + white-mask + black-mask matching, and a motion check confirms the scene is actually in slow-motion (so a stray match during fast action can't trigger a false speed-up). The header-text signal means solo boss fights work too: those have no party, so the L2/R2 allies prompt never appears — but the menu header still does.
2. Render — FFmpeg re-times each detected segment (setpts for video, atempo for audio, kept exactly in sync), speeding up the slow-motion while normal-speed combat passes through untouched, then stitches it all back together.

Detection normalizes any 16:9 resolution to 1080p internally, so the bundled templates work at 1080p / 1440p / 4K. Rendering happens at your source's native resolution.

Install

One line, everything bundled:

pipx install ffvii-realtime     # installs the `ffvii-realtime` command, isolated
ffvii-realtime gui              # opens the browser app

That's the whole setup: FFmpeg ships with it — nothing else to install. Drag your video into the app (or click Browse…, or paste its full path), set the speed-up factor, click Start — the finished file is saved next to the original.

Requires Python 3.8+. No pipx? Install it, or just use pip install ffvii-realtime (pipx only adds isolation). On Windows, check "Add python.exe to PATH" when installing Python.

Prefer the command line? After installing, the one-shot is (pass --game to match your footage):

ffvii-realtime fix my-fight.mp4 --game rebirth -o my-fight.realtime.mp4

See Command-line usage for previews, ranges, and other games.

Command-line usage

Specify the game your footage is from. Detection is HUD-specific and defaults to Rebirth. For Remake or Revelation captures you must pass --game remake or --game revelation (in the browser UI, choose it from the Game dropdown). The wrong game finds 0 segments.

# already installed via `pipx install ffvii-realtime` (contributors: `pip install -e .`)

# ALWAYS pass --game to match your footage: rebirth | remake | revelation.
# (It's optional and defaults to rebirth, but set it explicitly so non-Rebirth
#  footage isn't silently missed — the wrong game finds 0 segments.)

# the usual one-shot: detect slow-mo and render the real-time version
ffvii-realtime fix my-fight.mp4 --game rebirth -o my-fight.realtime.mp4

# Remake / Revelation footage:
ffvii-realtime fix my-remake-fight.mp4 --game remake
ffvii-realtime fix my-revelation-fight.mp4 --game revelation

# verify settings on a short window first (recommended)
ffvii-realtime preview my-fight.mp4 --game rebirth --range 4:40-5:20 -o test.mp4

# process only a section of the video (also makes detection faster),
# and mute the sped-up slow-mo audio
ffvii-realtime fix my-fight.mp4 --game rebirth --range 24:00-26:30 --tac-vol 0%

# separate steps — only `detect` needs --game; `render` reuses the saved intervals
ffvii-realtime detect my-fight.mp4 --game rebirth -o intervals.json
ffvii-realtime render my-fight.mp4 -i intervals.json -o out.mp4

# launch the browser UI (choose the game from the dropdown)
ffvii-realtime gui

Options

• --game rebirth|remake|revelation — which game's HUD to detect. Set this to match your footage — detection is HUD-specific, so the wrong value finds 0 segments. Defaults to rebirth.
• --range MM:SS-MM:SS — process only that section of the video; also speeds up detection since only that span is scanned.
• --tac-vol — volume of the sped-up Tactical-Mode audio, as a percentage (10%, 0% for silent, 100% for full) or a 0–1 fraction. Default 10%. (Ignored when seam bridging is on, since bridging replaces that audio.)
• --no-bridge-sound — turn off seam audio bridging. By default, speeding up a Tactical segment would make its audio cut out and jump; bridging instead crossfades the real before/after ambient across the seam so the sound stays continuous. On by default. --bridge-width (seconds, default 0.35) tunes the crossfade half-width.
• --lead — start the speed-up this many seconds before the menu is detected, to cover the panel slide-in. Default 0.2.
• --force — overwrite the output file if it already exists. By default the tool refuses, so you can't clobber a previous result by accident (the browser UI asks for confirmation instead).

The speed-up factor

--factor defaults to 100, which matches the game's default "Tactical Mode Slowdown" setting. If you changed that setting, your slow-motion is faster or slower, so pick a different factor. The easiest way to dial it in: run preview on a stretch with a long Tactical Mode and try a couple of values — when the sped-up sections look like normal-speed combat, that's your number. (Higher = snappier; the slow-mo is aggressive, so values in the 50–150 range are typical.)

Note: the default of 100× was arrived at by trial and error — rendering a tactical segment at several factors and picking the one that looks like real-time. It is not an officially documented figure, and the actual slowdown almost certainly differs per game and per in-game "Tactical Mode Slowdown" setting. If you know (or have measured) the real slowdown factors for any of the selectable Tactical Mode speed settings in any of these games, please open an issue — that input is very welcome and would let the tool ship accurate per-setting defaults.

Caveats

• Tested on Remake, Rebirth, and even Revelation footage The detection keys on the game's own UI, so it should work on any footage as long as the correct game (Remake, Rebirth, or Revelation) is specified — but please run preview on your own video before committing to a full render.
• 16:9 only. Ultrawide/non-16:9 captures will warn and may misdetect (the HUD anchors differently).
• Custom HUD settings (scale/opacity accessibility options) could shift the badge positions and break detection. Standard HUD is assumed.
• Pauses / loading / results screens are static (never slow-motion), so they're correctly left alone — they'll appear at full length in the output.
• A real character movement that happens during a slow-motion stretch becomes near-instantaneous when compressed — occasionally a character may appear to "jump." That's inherent to compressing slow-motion that contains motion, not a glitch.

Requirements

• Python 3.8+
• Everything else is installed automatically: numpy, opencv-python-headless, and FFmpeg (bundled via imageio-ffmpeg). If you already have your own FFmpeg on PATH — or set $FFVII_FFMPEG / $FFVII_FFPROBE — it's used in preference to the bundled build.
