Longest single avatar video by plan: HeyGen, Colossyan, Sume

Maximum length per video on the vendor pages read 2026-10-08: HeyGen 1 minute (Free), 30 minutes (Creator and Pro), 60 minutes (Business) and unlimited (Enterprise); Colossyan 20 minutes (Starter) and 30 minutes (Professional). Sume Avatar 1.0 accepts 4 to 60 seconds in one job. For anything longer on Sume you split the script into jobs and join the clips.

The gap is a factor of 30 at the 30-minute tier, so it should drive the choice for long-form work.

The caps

Neither vendor page says whether a long render is billed at a different rate. Credits and included minutes are the limit that applies in practice, so a 30-minute video may use the whole month's allowance on a small plan.

What 5 minutes costs on Sume

Five minutes is 300 seconds, so five jobs of 60 seconds. Standard is $55.20, Plus $73.50, Max $165.00. Ten minutes doubles that. Each job needs the same avatar handle and the same scene so the presenter stays consistent, and a join step stitches the files; the 3-minute example shows the cost of that step.

Cut points matter. End each 60-second job at a sentence boundary, because a cut mid-sentence will be audible after joining.

When the cap decides it

Choose a long-form editor if the deliverable is a 15-minute walkthrough in one file. Choose Sume if the deliverable is a series of short clips, social posts or API-generated per-customer messages, where 60 seconds is already long. The two can coexist: a long editor video for the course, short Sume clips for the promotion around it.
