Understand ratio and resolution
16:9 is a landscape shape; 9:16 is vertical; 1:1 is square. Resolution specifies pixel dimensions within that shape. For example, 1920×1080 and 1280×720 are both 16:9. Changing dimensions does not automatically create more detail than the source contains.
| Shape | Example canvas | Useful planning question |
|---|---|---|
| Landscape 16:9 | 1920×1080 | Can the viewer read the full interface or compare two elements? |
| Vertical 9:16 | 1080×1920 | What single subject or detail should lead each moment? |
| Square 1:1 | 1080×1080 | Does the layout still have enough room for the subject and text? |
These are example composition sizes, not current upload requirements for every platform. Check the destination’s current specifications before delivery.
Choose crop, fit or recompose
A crop fills the output by discarding part of the source image. A fit preserves the whole image but may leave unused space. Recomposition arranges the useful pieces differently: an enlarged interface detail, a speaker above the demonstration or a new title position.
Choose based on what the viewer needs to see. Center-cropping a face may work for a simple shot. Center-cropping a desktop tutorial can remove the menu being demonstrated. Fitting the entire desktop into a narrow frame may preserve all the pixels while making none of the text readable.
Plan for motion and multiple subjects
Check the subject’s full movement, not just the opening frame. A speaker may lean out of a narrow crop or gesture toward an object at the edge. For multiple speakers, decide whether the frame follows one person, alternates compositions or uses a deliberate split layout.
Do not let automatic subject tracking define the edit without review. A visually centered face may still be the wrong subject when the important action is happening elsewhere.
Rebuild text placement
Recheck line breaks, caption width, title size and hierarchy after changing the frame. Keep essential information away from expected interface overlays, while checking the actual destination preview rather than relying on a universal safe-area percentage.
An overlay that fits beside a landscape video may need to move above or below a vertical crop. Preserve the reading order and allow enough time for any newly wrapped text.
Validate each delivered version
Inspect a busy frame, the longest caption and the scene with the least available space. Watch the full vertical version on a phone-sized display. Confirm that the final export dimensions match the intended canvas and that the first and last frames are clean.
Use the long video to shorts brief for selecting a standalone excerpt and screen recording tutorial guide for interface-heavy compositions.
