Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Captions

  • Credit rollover limited to 3x monthly maximum, forcing spending within quarters
  • Free plan provides limited editing capability, requiring immediate paid upgrade
  • Minimum 3-day refund window and 10-20 percent credit usage threshold restricts refunds
  • Per-credit pricing model increases costs for high-volume video production
  • Enterprise plan requires custom negotiation with no transparent pricing

MiniMax H3 Generator

  • It is not MiniMax's product. The model belongs to them and this site states no affiliation, so a change upstream arrives here without warning.
  • No operator is disclosed anywhere, only a support email, which is thin ground for a service taking prepaid money.
  • The 50 free credits buy roughly one short 768P clip, so the free tier demonstrates that it works rather than letting you evaluate it properly.
  • Reference input is capped at nine images, three videos and three audio files with a 64 MB total, which is generous for a prompt and restrictive for a real edit.
  • Prepaid credits are held by an unidentified vendor and nothing on the site says what becomes of an unused balance if the service stops.
