Synthesia Pro's 6,000 to 48,000 credits in minutes of dubbing

At the credit costs on Synthesia's October 1 plans page, Pro's 6,000 credits cover about 60 minutes of video at roughly 100 credits a minute, or 75 minutes of dubbing with lip-sync at 80. The multiplied Pro tiers list 12,000 to 48,000 credits, which is 150 to 600 minutes of dubbing. These are my divisions of the listed numbers; Synthesia does not state the totals, and the page says plans do not change in price.

The table

The page also says Creator was renamed Pro. The 2x to 8x tiers are listed as 12,000 to 48,000 credits; I assume credits scale evenly with the multiplier, so the 4x and 6x rows are my arithmetic. No dollar value appears for any plan.

What the same minutes cost on Sume

Sume is billed in dollars per second, so you can price the same output directly. The H3 Max lip-sync route at 768p is $0.10 per billed second, so 75 minutes of lip-sync output is 4,500 seconds, or $450. Using 480p it is 4,500 x $0.0625 = $281.25. A like-for-like comparison needs the dollar price of the Pro plan, which I did not read, so I leave the comparison open.

How to use these numbers

• Estimate your monthly minutes of each kind: video, dubbing and surveys.
• Convert each to credits at the listed rates and add them.
• Find the smallest tier above that total, with a margin for retakes.
• For the Sume side, price the same minutes by second at the resolution you ship, and add the cheap steps (audio detach at $0.01 per job, timeline render at $0.10 per output minute).
• Compare dollar to dollar only after you have both prices.

Reading the table with care

Three cautions apply. First, the page lists video cost as about 100 credits a minute, so the video column is approximate; the dubbing and survey columns use exact figures. Second, one pool of credits serves every use, so a team that dubs 75 minutes has no credits left for video. Third, the signup allowances are separate from plan credits, so a trial does not eat into them. If your work is mostly dubbing, the dubbing column is the one to size from. If it is mostly new video, use the video column and treat dubbing as a bonus. Either way, add a margin for retakes, because a retake costs credits again.

What Sume does not do

Sume has no subscription credit pool and no tiered multipliers in the docs I read; you pay per job. It also has no one-click dubbing that rewrites lips on an existing video. The lip-sync route generates a new clip from a still and audio, so the two lists are not interchangeable line for line.
