Free AI content translation for video

AI content translation for video is the workflow of converting a video from one language to another — including voiceover, subtitles, on-screen text, and AI avatar lip-sync. Unlike text translation tools (Google Translate, DeepL), video translation needs to regenerate the audio in a native voice (or your cloned voice), re-render the captions, replace the on-screen text, and re-sync mouth movements. Fliki ships the end-to-end workflow in one click.

Upload your MP4 (or paste a YouTube URL), pick the target language and dialect, choose between a native AI voice or your cloned voice, and click translate. Fliki extracts the audio, transcribes it with timestamps, contextually translates the script (not word-for-word), regenerates the voiceover, re-renders the captions, replaces the on-screen text, and re-syncs the AI avatar lip movements. Export the new MP4 plus SRT subtitle files in roughly 5 minutes per language.

Yes. The free forever plan includes monthly credits, every aspect ratio, and translation into all 80+ languages, no credit card required. Voice cloning (preserve your voice across languages), AI avatars (lip-sync per language), longer videos, and 4K render are on paid plans starting at $28/mo.

Google Translate and DeepL translate text. They don't regenerate the voiceover. They don't re-sync the avatar's lips. They don't replace the on-screen lower-thirds. Use Google Translate/DeepL when you need a text translation. Use Fliki when you need the complete video translated end-to-end into the target language.

As of mid-2025: Rask AI and HeyGen are video-translation-first tools, the closest comps to Fliki. Fliki ships translation as part of the broader video creation workflow (script, voiceover, avatar, brand kit, 80+ languages all in one composer), with pronunciation overrides for brand/technical terms and 100+ dialect precision (Brazilian PT vs European PT). Tool capabilities change quickly — compare current feature sets and pricing before deciding.

Smartcat and Phrase are TMS (translation management systems) for text-heavy localization workflows — UI strings, marketing copy, docs. They don't ship video voiceover regeneration, avatar lip-sync, or on-screen text replacement. Use Smartcat/Phrase when localizing a product UI or website. Use Fliki when localizing video content end-to-end.

Yes — this is the unique Fliki value prop for branded video. Clone the original speaker's voice once (3-5 minute recording in any language). Fliki preserves the voice timbre, tone, and pacing when translating into Spanish, Mandarin, French, Arabic, and 75+ other languages. The founder sounds like themselves in every market.

Yes. When you enable AI avatar mode and translate the video, Fliki re-syncs the avatar's mouth movements to the new language's phonemes. A Spanish-translated talking-head video shows mouth movements matching the Spanish audio, not the original English. The result looks native, not subtitled.

Fliki uses LLM-based contextual translation, not direct word-for-word translation. The subtitle says what a native speaker would say in this context, not what Google Translate would produce. Add pronunciation overrides for brand names and technical terms (e.g., "Kubernetes", "OAuth") to lock those words from being translated. Many users find the translation comparable to professional human translation for product, marketing, and training content — though for high-stakes publishing, a native-speaker review pass is recommended.

Yes, into 100+ regional dialects. Brazilian Portuguese vs European Portuguese. Mexican Spanish vs Spain Spanish vs Argentine Spanish. UK English vs US English vs Australian English vs Indian English. The dialect-level precision required for credible regional broadcasts and customer-facing video.

Yes. In addition to the translated MP4, Fliki exports SRT subtitle files in every target language. Drop them into YouTube's caption manager (or YouTube's multi-language audio track feature), Vimeo, your LMS, or your CMS for closed-caption tracks. SRT caption tracks support WCAG 2.1 accessibility guidelines in every region.

Standard ($28/mo) covers small teams translating a few videos a month. Premium ($88/mo) unlocks voice cloning, AI avatars with lip-sync, longer renders, and 4K — typical for brands running multi-market global launches. Enterprise plans available for media companies and global brands localizing entire video libraries at scale via the API.
