The Remix tab is designed for editing and adapting existing video files or links. It excels at three primary use cases:
  1. Automated Translation & Dubbing: Translating the speech in a video to another language.
  2. Script-based Remixing: Replacing the original voiceover with a custom narration script.
  3. Split Screen Production: Laying two videos side-by-side or stacked vertically (e.g. for reaction videos or gameplay overlays).

​
πŸ“₯ Step 1: Input & Basic Settings

  • Input Type: Choose Video link (pastes a URL from YouTube, Facebook, or TikTok) or Video file (upload a local file).
  • Filters & Effects: Apply visual filters and audio equalization presets.
  • Volume: Adjust the volume of the original track.
  • Dim Screen: Toggle screen dimming to overlay texts cleanly.

​
πŸŽ™οΈ Step 2: Translation & Dubbing (Voice Cloning)

By checking Translate videos, you activate nQivi’s automated translation engine.
  • Target Language: Select one or more target languages.
  • TTS Engine & Voice: Choose which TTS engine (Gemini, ElevenLabs, MiniMax, EdgeTTS) and specific speaker profile will perform the new voiceover.
  • Dubbing Pacing Modes:
    • Uniform Ratio (Keep Duration): Scales the entire translated voiceover by a single factor to fit the original video’s length.
    • Segment Match (Keep Duration): Breaks the speech into segments and speeds up/slows down each segment independently to sync with original visuals precisely.

​
πŸ“ Using a Custom Script or Custom Audio

Instead of translating the original speech, you can replace it entirely:
  • Use my script: Check this box to type or paste a custom script. The original speech will be replaced with a synthesized reading of your new text.
  • Use custom audio: Check this to overlay an uploaded audio file (e.g. your own pre-recorded microphone recording).

​
πŸ“± Step 3: Split Screens (Dual Layouts)

Perfect for reaction videos, gameplay narration, or TikTok split-screens.
  1. Check Use split screen.
  2. Aspect ratio: Set to 9:16 Portrait for mobile platforms.
  3. Second Video Input: Upload a local file or paste a link (e.g. a Minecraft parkour video or ASMR satisfying clip).
  4. Layout Orientation:
  • Vertical: The two videos are stacked (one on top, one on bottom).
  • Horizontal: The two videos are side-by-side.
  1. Split Ratio: Adjust the slider to set how much percentage of the screen width/height the first video occupies.
  2. Volumes: Separately balance the volume of the first and second video tracks.
  3. Trim: Set the start trim offset (in seconds) for the second video.

​
πŸ”€ Step 4: Captions & Overlays

Same as the Autopilot module, you can:
  • Enable stylized, highlighted subtitles.
  • Import or export .srt caption files.
  • Overlay watermarks, greenscreen chroma-key effects, and moving text/images.
