For newsletter writers

Give your newsletter header images and a promo clip

PrismPoster is a creation studio for the visuals a newsletter needs. Generate hero and header images, quote-card graphics, and a short promo video to announce each issue — you write the words, PrismPoster makes the visuals.

The usual workflow

01

A strong issue still goes out with a plain or stock header image

02

Quote-card graphics take design time you would rather spend writing

03

You have nothing visual to announce the issue with

04

Stock imagery rarely matches the tone of what you wrote

The PrismPoster run

One source in, a reviewed set out.

01

Generate the header

Make a hero or header image in Image Studio from a prompt, steering the look with cinema modes and camera treatment, then refine it in Magic Edit with retouch, restyle, and upscale.

02

Make quote cards

Turn the strongest lines from your draft into quote-card visuals in Image Studio, formatted for both the issue and a vertical share, using an @tag reference so the set stays on-brand.

03

Add a promo clip

In Video Studio, animate the header with image-to-video for a short 4 to 10 second promo clip to announce the issue, then review and export server-rendered 16:9 and 9:16 files. You write and send the newsletter yourself.

A worked example

One issue, one header, three cards

This week's issue is 1,800 words on why remote-first hiring stalled. The writing is finished. What is missing is a header that is not a stock photo of a laptop, something to pull the best lines out, and anything at all to announce it with.

  1. 01

    A header that matches the argument

    In Image Studio, describe the idea rather than the topic — an empty office floor at dusk, chairs still pushed in — and set a cinema mode for the mood. Specifics beat adjectives here: naming the light and the objects gives the generation more to work with than asking for something "professional".

  2. 02

    Fix the frame

    Take the best result into Magic Edit. Outpaint it wider so the header crops cleanly at email width without cutting the subject, retouch anything distracting, then upscale. If a restyle goes too far, the before/after history holds every earlier version.

  3. 03

    Three quote cards as a set

    Pick the three sharpest lines from your draft and generate a card for each, attaching the header you just finished as an @tag reference so all three inherit its palette and treatment. Export each at 16:9 for inside the issue and 9:16 for a vertical share.

  4. 04

    A promo clip for the announcement

    In Video Studio, run image-to-video from the header so the clip opens on the image subscribers will see at the top of the email. Ten seconds at 9:16 is enough to announce an issue, and director mode keeps the camera move slow rather than frantic.

A header, three matching quote cards, and a short vertical promo clip — all built from the issue you already wrote, and all exported as server-rendered files you drop into your own email tool.

Common questions

Does PrismPoster write or send the newsletter?

No. It makes the visual and audio media, not your headlines, captions, or body copy, and it is not an email platform. You write the issue and send it from your existing tool — PrismPoster produces the header, the cards, and the clip that go with it.

How do I keep the visuals looking like my publication?

Save a header you are happy with to your Library and attach it as an @tag reference image on later generations. Reference images guide the model toward a style and composition you already have, so a run of issues reads as one publication rather than a different look every week.

My header keeps getting cropped badly in email. What can I do?

Use outpaint in Magic Edit to extend the image beyond its original borders, which gives you margin to crop into without cutting the subject. Then preview the export in its target shape before you commit — a composition that works at 16:9 often needs recentring for a vertical share.

Can I do all of this on the Free plan?

The images and edits, yes: every studio including Magic Edit runs on a free account, drawing on 150 starter credits pooled across Image, Music, and Video in many countries. Those credits cover up to five 4-second 360p clips (or one at 720p), so a weekly promo clip wants a credit pack, from €3.99 with no subscription. Unused starter credits expire 72 hours after they are granted.
