What size Tiny Desk AI video should you make?
The template fixes the length; you choose the frame and the resolution. For the platforms this trend lives on, that choice is close to made for you — but the export is only half the job, because every clip is silent.
The three frames
Vertical 9:16 fills a phone screen and is the default for TikTok, Instagram Reels and YouTube Shorts. Square 1:1 survives feed crops and works for a carousel or a static post. Landscape 16:9 suits a site embed, a YouTube long-form cut or a slide.
If the clip is going to a phone, choose 9:16. Cropping a 16:9 render into a vertical frame afterwards throws away the framing the template was built around.
Resolution: 768P or 2K
768P is enough for a phone screen and is what the standard price buys: 10 credits for a 14-second clip. 2K costs 16 and is worth it when the file will be edited, enlarged, shown on a desktop or reused in something else. Both come from the same template, so the difference is detail, not composition.
Every clip is silent by design
The render carries no audio track: no singing, no speech, no room sound. The performance is visual, and the mouth movement comes from the reference clip rather than from a track you supplied.
That is not a limitation to work around so much as how the trend travels: you add a licensed or trending sound inside the platform, where the rights to that sound already live. Add the sound in TikTok, Reels or Shorts rather than in an editor before upload, so the platform recognises the track.
Captions are yours to add
No titles or subtitles are burned into the file. If you want a line on screen — the joke, the credit, the “made with AI” label — add it with the platform’s own text tool or your editor. A short line at the start is enough to make the clip honest without spoiling it.
Posting checklist
Use a portrait you own or are authorised to use. Keep the clip labelled as AI-generated rather than as real footage of a real event. Clear the rights to the sound you add. Then check the exported file itself — not the preview in the workspace — for framing and detail before it goes out.
