Quoted as 3–5 by major vendors. Realistic for short-form is 5. Rush fees do not move it under 2.

Every word.
Frame-accurate.
Speech is transcribed with word-level timestamps and formatted into a broadcast-spec VTT — 32 char/line, ~17 char/sec, proper cue structure. Drops directly into your delivery workflow.

Raw visual descriptions are rewritten to broadcast AD conventions — present tense, objective, concise — and timed to each available silence window. Production-ready, not a draft.

§ 07 · Common questions
Anything
else?
Q.01What kinds of video does Post Slate work with?
Any short-form business video — ad spots, corporate training, brand films, product demos, recorded events, investor content. Credits scale with video length: 1 credit per video up to 2 minutes, 2 credits up to 5 minutes, 3 credits up to 10 minutes.
Q.02Does the VTT file meet broadcast spec?
Yes. VTT output follows FCC broadcast requirements — 32 characters per caption line, ~17 characters per second reading speed, proper cue structure.
Q.03What's the audio description quality like?
Broadcast AD conventions — present tense, objective, concise, timed to dialogue gaps. The voiceover is rendered by a professional-grade AI voice tuned for neutral broadcast narration. Production-ready.
Q.04What about videos longer than 10 minutes?
Standard processing tops out at 10 minutes (3 credits). For longer corporate content — training series, town halls, recorded webinars — get in touch.
Q.05What happens if processing fails?
Post Slate delivers gracefully. If one step fails you still receive completed outputs. Your credit is not deducted for failed jobs.
Q.06Do credits expire?
Never. Credits have no expiration. Buy a pack for a busy production cycle and use them across projects over time.
Q.07How long are my files stored?
Files are retained for 30 days after processing. You'll see a warning at 25 days.
Q.08Will you ever add subscriptions?
No. Credits-only is a deliberate product decision. There will never be a monthly minimum.
