Test an avatar's look with a 4 second clip before a 60 second run

Run a 4 second clip first. It is the shortest job Sume accepts and costs $0.736 on standard (4 x 0.184), against $11.04 for a 60 second clip (60 x 0.184). If the face, the voice or the framing is wrong, you find out for 6.7 percent of the long-run price.

What to check in the test

Open the finished clip at the size viewers will see and check these things before spending more:

• Does the face match the photo or prompt you used, in the frame you will publish?
• Does the voice suit the brand? The avatar's voice is part of the avatar.
• Is the aspect ratio right for where it will run?
• Do inline captions read correctly if you turned them on? A caption failure is a soft failure and the clip still succeeds.
• Does the spoken text match your script? Listen with the script in hand before publishing.

Preview or test clip

There are two cheap checks and they answer different questions. An Avatar video preview shows first-frame stills without starting the render, so it answers 'does the composition look right'. A 4 second test clip answers 'does it move and sound right'. The preview's own price is not listed in the pages we read, so read the amount in the job estimate before relying on it.

Use the same Idempotency-Key discipline for both: one key per intended job, a new key for a changed payload.

What the test cannot tell you

A 4 second sample cannot show drift across a long clip, because clips of 4 to 12 seconds are planned and joined for longer scripts. Check the first, middle and last scenes of the final render, and keep the approved script with the output. If the result is wrong, a rerender at the same length costs the full amount again.

A routine you can repeat

Make it a habit for every new avatar: create it for $0.95, render a 4 second test on standard for $0.736, and approve the result before any longer job. The total spent before a long run is $1.686. If the test fails, change the avatar's input and create a new one, since you cannot rely on an old handle changing its look.

Record the approved test next to the handle in your own files, so that later disputes about what the avatar was supposed to look like have an answer.

Use a test line that includes the sounds your real script uses most, such as product names. If the name sounds wrong in four seconds, change the spelling or wording in the script before the long run, because the fix costs far less now than later.
