Add Filter
Apply a visual filter/look to a video or image. Use ONLY for look presets. Do NOT use for brightness/contrast/warmth/saturation tweaks — use color_grade instead.
Add Transition
Add entrance and/or exit transition animations to any visual overlay.
Color Grade
Fine-tune how the video/image looks — brightness, contrast, warmth, color pop, shadows, highlights, etc. Use this for any 'make it brighter / warmer / more vivid / darker / moodier' request. Do NOT use add_filter — that is only for named look presets like black-and-white or Kodak.
Apply Color Look
Apply a professional color look to a video or image. These are high-quality film-grade color transforms for the final render.
Rotate
Rotate an overlay by a specified number of degrees.
