Localize · Your spot, another language WAV STEM · SRT · VTT · TXT · PDF / Spanish & French · No voice cloning
Finished spot in · Localized stem out

The file your editor actually asked for.

Everyone else hands you a translated video. Localize gives you the assembly-ready piece a real post workflow wants: a broadcast-grade localized voiceover stem — WAV, 48 kHz/24-bit, −24 LUFS, aligned to timecode zero, full source duration — plus subtitles, a translated transcript, and a per-line fit report. Upload a finished spot, video or audio. Spanish & French. Rights-safe studio voices — no voice cloning.

How it works

Upload. Localize.
Drop it on the
timeline.

One upload replaces the translation vendor, the VO studio, and the audio-post handoff. Pick a language, audition voices, and get back a stem that lands where your English one did.

What you get back

One upload.
The whole
stem package.

The headline deliverable is the voiceover stem — the file your editor drops at 00:00 so every line lands in its original window. The rest of the package is built around it.

Who it's for

Built for the
multi-market
buy.

Agencies & brands

Running US Hispanic or Canadian French media off an English master? Localize the approved spot into Spanish or French and get a broadcast-grade stem your editor drops straight onto the timeline — no vendor chain, no VO booking.

Radio & audio advertisers

No video required. Upload a plain audio spot — MP3, WAV, M4A — and get the localized voiceover back as a broadcast-loudness stem, ready for trafficking.

Post houses

Localize a client's spot without booking a VO session or chasing a translation vendor. Audition voices, review line-by-line, and hand off the stem your timeline expects.

Rights-safe by design

No cloning.
No clearance
headaches.

The differentiator isn't just speed — it's that nothing leaves without a person signing off, and no one's voice is copied to get there.

Your talent stays your talent

We never clone a voice.

You pick from curated studio voices and audition them instantly and free — assign a distinct voice to each speaker on a two-speaker spot. No talent voice is copied, so there's no usage-rights or union exposure to manage after the fact.

Human in the loop

You approve before it's final.

Every localization goes through a review editor — line-by-line playback against the video, editable subtitles, and any line that runs long flagged and highlighted. Downloads unlock only after you've checked it. Translation is engineered to fit each line's window; the ones that don't are surfaced, not buried.

Localize runs on the same credits and the same packs as the rest of Post Slate — charged per language, scaled to the length of the spot.

Common questions

Anything else?

Q.01What exactly do I get back?
A localized voiceover stem (WAV, 48 kHz/24-bit, −24 LUFS, full source duration, aligned to 00:00), subtitles timed to the translated audio (SRT + VTT), a translated transcript (TXT + PDF), and a per-line fit report. Optionally, upload your M&E stem to also get a finished localized mix.
Q.02What is the voiceover stem, exactly?
The localized voiceover alone — a WAV at 48 kHz/24-bit, broadcast loudness (−24 LUFS, ATSC A/85), the full duration of your source, aligned to timecode zero. Drop it at 00:00 and every line lands in its original window. It's the assembly-ready stem a real post workflow wants — not a re-rendered video.
Q.03Do you clone my talent's voice?
No. We never clone your talent's voice. You choose from curated studio voices and audition them instantly and free — so there's no usage-rights or union exposure. Two-speaker spots are supported; assign a distinct voice to each detected speaker.
Q.04Which languages are supported?
Spanish and French today. The system is built to add more languages over time.
Q.05What can I upload?
MP4, MOV, MP3, WAV, or M4A — video or audio — up to 10 minutes and up to 2 GB. Radio and audio-only spots work with no video required.
Q.06Is this lip-sync or on-camera dubbing?
No. Localize is for voiceover-driven spots. We deliver a localized audio stem your editor drops onto the timeline — not a re-rendered video, and not on-camera dialogue replacement.
Q.07Can I get a finished mix, not just the stem?
Yes. Upload your music-and-effects (M&E) stem and get a finished localized mix back at the same broadcast loudness, alongside the standalone voiceover stem.
Q.08How does "translated for time" work?
Spanish and French copy tends to run longer than English, so the translation is engineered to fit each line's original time window — not just its meaning. Any line that still can't fit is flagged for your review, never silently rushed.
Q.09Do I review before downloading?
Yes. Every localization goes through a review editor — line-by-line playback against the video, editable subtitles, flagged lines highlighted — before downloads unlock. It's AI translation with mandatory review: you approve it before it's final.
Q.10How many credits does a localization cost?
Charged per language, by length: 2 credits up to 2 minutes, 3 up to 5 minutes, 4 up to 10 minutes. Same packs as the rest of Post Slate; three free credits on signup; credits never expire. A failed run refunds automatically.
Q.11I already delivered a spot through Post Slate — can I add a language?
Yes. Add Spanish or French to any spot already delivered through Post Slate Compliance in two clicks — same account, same credits. See the package →
