Prompt
What your agent receives from get_technique.
Technique: Bright Vibrant Grade.
Apply to: {clip}, or the part the user names.
Look and method: Raise `vibrance` so dull colors gain more than colors that are already strong, lift brightness and midtones a little with `eq`, warm it slightly, and stop before skin turns orange or whites clip.
Spec first: turn every style word into numbers (frames, pixels, percent, dB) and tell the user before you build.
FFmpeg starting point, adjust values to the footage: ffmpeg -i "{clip}" -vf "vibrance=intensity=0.4,eq=brightness=0.03:saturation=1.1:gamma=1.04,colortemperature=temperature=6000:pl=0.5" "{output}"
Probe the source first for size, frame rate, pixel aspect, audio stream and whether it has any color. Sizes in the command are examples, so set them to the source. Color changes do nothing on black-and-white footage, a clip without audio needs its audio options removed, and H.264 for players needs -pix_fmt yuv420p.
Keep: Protect skin tones and keep the source untouched.
Check: Check waveform and vectorscope.
Quote every file path, show a preview of the affected section, and do not overwrite the source.
