Features

• Add Subtitles: Quickly detect speech and generate subtitles. Translate into 100+ languages to reach global viewers with ease.

• Video Translation: Generate multilingual translated subtitles in real time with accurate audio-video sync—reducing repeated alignment and rework.

• Rewrite & Dub: Edit speech and rewrite subtitle text to better match your target audience. Enjoy more precise, more natural lip sync.

• Add Voiceover: Smart AI voiceover with ultra-realistic voice cloning—making narration sound more human, expressive, and textured.

Editing & Workflow

• More flexible subtitle styling: Set global styles, or create and adjust per-subtitle presets—independently, without affecting each other.

• Precise timeline editing: Zoom the timeline for more accurate subtitle timing and alignment.

• Drag to adjust start time & duration: Drag subtitle blocks to change start time; stretch the block to adjust duration and pacing.

• Visual subtitle order control: Reorder playback by dragging subtitle tracks—ideal for multi-speaker or multi-paragraph videos.

• Voice selection, switching, and preview: Add/switch voices with instant preview; one-click update to sync after changing a voice.

• Cleaner audio: If translated voiceover overlaps with the original audio, turn off the source-language track for clearer narration.

• Smoother volume control: Adjust volume in sync at the track level; after splitting, fine-tune volume for individual segments within the same track.

• Controllable speaking rate: Change the length of a voice block to control speed—for a more natural or more compact delivery.

• CPL control: Adjust CPL (characters per line) to control subtitle line length and fit different platforms and reading habits.

• Upload completion notifications: Get an email when processing is finished—no more waiting or refreshing.
