Read the plan limits before starting
Help pages often state limits that decide a project's shape. Synthesia's download article says basic and trial users cannot download videos. HeyGen's export article is written for paid users. LTX Studio's sharing article says every invitee needs an account. From 3 source pages, read 2026-09-25; no maker pays to be listed.
These lines are easy to miss on a product page and plain on a help page.
Read the export and sharing pages first, since they are the steps at the end of a project.
A limit found at the start changes the plan; one found at the end changes the deadline.

2A generator's own guide on this
Set beside “Read the plan limits before starting”, two passages from the guides SceneMixer publishes about its own pipeline:
It is fixed once you continue past the first step. For the other shape, start a new project with the same script.
SceneMixer, What Comes Out — “Can I change the aspect ratio after generating?” (read 2026-10-13)
The cast is generated once, at the start, as full-body reference sheets. Every segment that features a character is generated against that character's sheet, with face and body crops attached as references — so the face in episode 1 is the face in episode 40.
