A monthly quantity that is not a quantity of video
A credit allowance is a quantity of internal currency granted each billing period. It becomes a quantity of video only once the page also states how much output a credit buys and how long a credit lasts. As of 2026-09-12.
| Channel | What the allowance is stated as | Read from |
|---|---|---|
| Hedra | 1,500, 5,400 and 14,400 credits a month against $15, $30 and $75 | The pricing page |
| HeyGen | 600, 1,000 and 1,500 credits a month, with consumption stated to vary | The pricing page |
| Morph Studio | Monthly credit allowances, with no consumption rate published | The pricing page |
| Synthesia | 1,200 credits a month stated as 10 mins of video, 3,600 as 30 mins | The pricing page |
Inclusion rule. Channels publishing a monthly credit allowance without a per-second rate. A channel publishing credits against a second belongs to the credit-rate shape instead. Order. Alphabetical by channel name.
1Three figures make an allowance into a rate
The money, the quantity of credits, and how much output a credit buys. Miss the third and the allowance prices a month of access; miss the second and there is nothing to divide. One of the channels above publishes all three in minutes rather than seconds, which is the closest any allowance page here gets.
2The lifetime is the fourth figure, and it is usually missing
An allowance that lapses monthly means the effective rate depends on how much of it gets used, so a buyer consuming half is paying twice. That multiplier is larger than most of the differences a comparison of allowances would turn up.
3Stating that consumption varies is honest and unhelpful
One page above says outright that the credits a video uses change with the model, the duration and the complexity. That is more accurate than a single fabricated average and it means the allowance cannot be converted into output at all.
4An allowance is a cap, and what happens at the cap is a separate question
Stopping, queueing and charging at a higher rate are three different outcomes for a delivery date, and pricing pages rarely answer which one applies in the same place as the allowance figure.
5An allowance and a balance are different products
Credits granted with a plan and credits bought outright usually behave differently, and where a page merges them into one balance it has removed a whole class of question: which pot is spent first, and which one evaporates.
Where they are kept apart and the spending order is unpublished, assume the perishable pot goes first and plan the month around it. The assumption costs nothing if wrong and saves an allowance if right.

7The production behind the price
Price aside, what goes into the seconds behind “Credit allowance” is described in SceneMixer's guides:
Segments are numbered within their episode and the numbering is maintained for you when you insert or delete one.
SceneMixer, What Is Inside a Project — “Can I reorder segments?” (read 2026-10-13)
Paste a scene or a short script and SceneMixer gives you a storyboard — numbered shots with framing and seconds — and then a moving version of each segment, which you can join into a rough cut of the scene.
