Yella Umbrella or CaptionsHero?
Choose Yella Umbrella if
- You deliver STL, PAC, IMSC-Rosetta, or TTML, or you encode DVB, Teletext, or CC 608/708.
- You also produce audio description, dubbing, or voice-over in the same suite.
- You need TPN Gold Shield, or a private task server in your own AWS account, and two days of paid consultancy to set it up.
- Your team works a few days a month, and EUR 1 per active user per day plus the per-file and per-minute fees costs less than a flat plan.
Choose CaptionsHero if
- You want one flat monthly price with AI minutes, waveform, QC, and storage included, and no per-day, per-file, or per-minute fees.
- Each language needs a reviewer who can request changes and approve. Stellar's help pages show task statuses and a per-line Approved checkbox, but no request-changes step.
- You want 1,500 AI minutes a month at $149, with no third-party AI cost added on top.
- You want the price fixed before the month starts, not counted by active user days.
- You want one dashboard for who has which language, with email notifications for assignments, comments, and approvals.
- You deliver SRT or VTT for web and streaming video, and you need no broadcast encoding.
