Common questions

What does the fair use allowance mean?

Pro covers 300 videos a month — around 10 a day. The cap is there to stop account sharing and automated bulk usage. It resets on the 1st of each month.

What happens if I reach 300?

You can't process new videos for the rest of that month, and it resets automatically at the start of the next one. You're never charged extra and your account is never suspended.

What do I get on the free plan?

3 videos a month with every feature — subtitles, titles and line-by-line proofing. You export the full video, with just a small subvo watermark that Pro removes.

Are there limits on video length or size?

Up to 3 minutes and 50MB per video, in MP4, MOV or WebM. 1080p or 4K footage straight from a phone can go over 50MB — export at 720p or pick the smaller-file option in your editing app.

How do I cancel? Can I get a refund?

Cancel in one click inside the app — no emails, no support ticket. Cancel within 7 days of your first payment and you're refunded in full automatically and the subscription ends immediately (once per account). Cancel after that and you keep access until the end of the period you've paid for, with no further charges.

Will the plan or price change on me later?

No. The plan terms and price of existing subscribers won't change because of changes we make.
