Inspector → **Format** sets the aspect you edit in — and the default for Export. Frame rate, quality, and resolution live in the **Export Movie** dialog, not here. ![Social and Classic destination swatches, Social Safe](/files/sMvhqDhh5q6zXsSIGmNG) Same show, same moment, one photo on stage — each destination frame side by side. ## Social Tall frames for phones and feeds. ### TikTok Reels · Shorts · 9:16 (1080×1920)

## Social Safe An **export mode**, not a Look — same toggle in two places, on purpose. Built for tall frames that hate letterbox bars. **Format tab** (Inspector → **Format**) is the live one. Turn Social Safe on here so the **preview** shows the safe frame while you edit: photos, captions, and mats sit inside the crop *before* you encode.

Format tab: Social Safe checkbox so the preview matches the share crop — Social Safe — Format inspector (live preview)

**Export Movie** is for **this file**. The dialog’s Format swatches and Social Safe apply to that encode only — they do **not** change the live preview. Compose in YouTube 16:9 on the Format tab, then export a TikTok 9:16 with Social Safe without switching the whole workbench. Frame rate, quality, and resolution live only in Export.

Export Movie: Social Safe keeps photos and captions inside the frame — Social Safe — Export Movie dialog (this encode)

Turn it on to fill tall frames with soft stage wash, keep mats and effects, and clamp Photo Size to about **85–98%**. It turns **on** automatically for **9:16**, **4:5**, and **2:3**. It stays **off** for Square, 16:9, and the other Classic frames. You can still toggle it by hand. ## Export Movie Toolbar **Export** or **File → Export Movie…** (**⌘E**). ![Save As, Format, Social Safe, Quality, Frame Rate](/files/brXtYCkV3cOlpPqOBtT9) * **Save As** — filename; **Browse…** for the folder. Default name prefers title text, then the project name, then **Untitled Memory**. The file is `.mp4`. * **Format** — destination swatches for **this encode** (does not change the live preview) * **Resolution** — **1080p** (default) or **4K**. 4K takes much longer — around three times the length of the show. **Cinema (21:9)** does not offer 4K — that format stays at 1080p because of the aspect, not the Mac. Rarely, when other apps leave too little free memory, 4K declines to start and asks you to close some apps or use 1080p. If memory tightens mid-export, the encode slows rather than failing. * **Social Safe** — same mode as the Format tab * **Quality** — slider stops **Compact**, **Share**, **High**, **Best** (**Share** is the default). Available in Essential and Studio; Studio also shows the target rate in Mbps. * **Frame Rate** — **30** (smaller/faster) or **60** (smoother motion) Check the footer **projected size** (and duration) for the current choices. Click **Export** and wait. Toolbar shows **Creating memory…** and a percent. Editing pauses (*Edits paused while creating memory*). If music is still decoding, Export waits. You get an H.264 MP4; the `.memorystring` project stays editable. Preview with **Space** (and Studio **Warm Now** if you want the baked pass) before you export — the file matches that show, not the workbench ambilight. Every movie eases to the stage floor before the end hold (black on Dark, cream on Light). A subtle bottom-right **Created with MemoryString** watermark (logo + credit) fades in once during the tail of the last photo and stays through the end floor (about three seconds). On **Light** stage the credit uses the logo’s **bronze** brown. There is no toggle to disable it. ## Before you export * Preview with **Space** and scrub for timing issues. * Confirm music rights for imported audio. * Check the Export dialog’s format matches where you will post. * **⌘S** so the project is saved alongside the MP4. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://memorystring.codebyz.com/share/export.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
