The short-video export checklist

Choose a frame for the way people will watch

Portrait 9:16 gives a short video a tall canvas. Square 1:1 gives you a more balanced composition. Neither choice guarantees that a social platform will present every pixel unobstructed, so keep important text away from the outer edges.

In Hypit.me, the portrait export is 720 × 1280 and the square export is 720 × 720. The image fills the canvas and may be cropped. Preview both formats before choosing, especially when the subject is close to the edge of your source image.

Check the whole story, not just the first frame

Play the draft from beginning to end. Look for a clear opening, a middle that adds information, and an ending that gives the viewer somewhere to land. Check that a sentence is not interrupted by a cut and that a scene does not remain after its text has stopped being useful.

Hypit.me uses three scenes of equal duration, between three and eight seconds each. The default is five seconds per scene. For a longer sentence, either shorten the caption or allow more time for every scene. Complex multi-shot edits are better suited to a full editor.

• The text is readable at the smallest likely screen size.
• The subject remains in frame after cropping.
• Every scene has a distinct job.
• The final action matches what is actually available.

Know what the exported file contains

The browser studio records an animated image and captions as a silent WebM video, using the browser’s MediaRecorder support. Recording runs in real time; a 15-second draft takes about 15 seconds to export. Keep the tab active until the file is ready.

WebM is useful for previews and web playback, but acceptance varies across upload destinations. Check the destination’s current file requirements. If it needs MP4, convert the downloaded file with your normal video editor before uploading. Hypit.me does not add a voiceover or music track.

The JSON download contains your template identifier, script, scene duration, aspect ratio, and shot notes. The text download contains a readable brief. A custom local image is not bundled into these downloads; keep the original image with your project files.

Check your source material and claims

Confirm that you can use each image, voice, and piece of music for your intended audience and distribution. An image found online is not automatically available for reuse. If you are working for a client, ask them to confirm the source and permitted use of supplied assets.

Read the captions for factual claims and implied endorsements. Generated images should not be presented as proof that a real person used a product or that a product performed in a particular way. Replace unsupported promises with observable descriptions.

Open the downloaded file before publishing

A completed export is only one checkpoint. Open the downloaded file and watch every scene. Confirm the duration, the crop, the absence of black frames, and the final caption. Try it on a second device when the video is important to a launch.

Keep your script and image alongside the final video. That makes it possible to recreate the work when you need a different aspect ratio or a corrected line. Your browser draft is convenient, but it is local to the browser and should not be your only copy.

• Video opens and plays from start to finish.
• Captions match the reviewed script.
• The chosen image is present in all three scenes.
• Duration and aspect ratio are appropriate.
• Original assets and the exported brief are saved.
