One post, every channel
The same message usually goes out in more than one place. A post in ANVL can now hold a frame per channel — 4:5 for Instagram and Facebook, a story, a LinkedIn version — side by side, each composed for its own format and checked against its own channel's rules.
An announcement rarely goes out once. The new colleague, the opened office, the event next month — it goes on Instagram, on LinkedIn, maybe as a story, maybe on Facebook. Same message, three or four shapes. And each shape is a different picture: a story is tall and has the app's buttons sitting on top of it, a LinkedIn image is wide, the feed on Instagram shows a portrait frame largest.
Until recently, each of those was a separate thing to make in ANVL. Now they can be one post.
Frames side by side
A post can hold a square, a 4:5, a story and a LinkedIn version next to each other. Ask for the same post as a story or the same for LinkedIn, and the new frame is built from the one you are looking at: the same headline and the same message, recomposed for the new format rather than stretched to fit it.
Or ask for all of it at once. One post for Facebook, one for Instagram and one for LinkedIn gives one post with a frame per channel, in the order you named them. The channel decides the format: Instagram and Facebook get 4:5, LinkedIn 1.91:1, a story 9:16. Say square or story and that is what you get instead.
The editor, the thumbnails, presentation mode, the PDF and the PNG export all show each frame in its own format, and the export dialog says the size of every file, so you know which image goes where.
If one frame needs a different shape, the format dialog asks whether the change applies to this frame or to all of them. Choose this frame, and only that one changes; its content is redrawn for the new size.
Each channel by its own rules
This is the part that is easy to miss. A brand kit can have rules per channel — how a call to action is phrased, whether emoji or hashtags are allowed. Those rules now follow the frame, not the post. If your brand forbids emoji on LinkedIn, the LinkedIn frame is flagged for it, even when the rest of the post is for Instagram where emoji are fine.
What stays one format
A carousel is still one format throughout, because it is published as one post and swiped through. A one-pager's pages are one document. Those are not versions of a message; they are a single thing in several parts.
If you are evaluating ANVL: this is what on-brand means in practice for social. Not the same image cropped four ways, but the same message composed four times — once per place it is going, each checked against what that place allows.
