Editing a thumbnail

Moving and resizing the subject

The most common flaw in a generated thumbnail is not the subject or the style. It is where they are standing.

Moving and resizing the person

Six one-click actions in the editor's Avatar tab reposition the main subject in a finished thumbnail and reconstruct the background they were covering:

ActionWhat it does
Move to LeftRepositions the subject into the left third, inpainting behind them
Move to CenterCentres the subject
Move to RightRepositions into the right third
Make BiggerEnlarges the subject toward a close-up
Make SmallerShrinks them so more background shows
Face CameraRotates them to face the viewer directly

Each is one edit and one request. Identity, background style and any text stay as they were.

Pro and up

The Avatar tab — position, swap, pop-out and remove — unlocks on Pro. See plans and limits.

Why this beats regenerating

The most common flaw in a generated thumbnail is not the subject or the style — it is placement. The person is dead centre and there is nowhere for the headline to go, or they are too small to recognise at sidebar size. Regenerating rolls the dice on the entire composition to fix one thing. These actions fix only that thing.

Where the subject should actually be

  1. Off-centre beats centre. Subject in one third, text in the other. A centred subject with text on both sides fights itself.
  2. Bigger than feels right. Design at 1280×720, consumed at 168–360. If the face looks slightly too large on your monitor, it is about right in a feed.
  3. Face the camera for reaction content. Direct eye contact is a stronger hook than profile — that is what Face Camera is for.
  4. Smaller for scene-led videos. Travel, real estate and build videos are about the place. Make Smaller lets the location carry the frame.
  5. Leave the safe zones clear. The bottom-right corner is covered by the duration badge on YouTube. Nothing important goes there.

Actions vs. pop-out

 Avatar actionsPop out & move
PrecisionPreset thirds and sizesDrag to any pixel
ReliabilityConsistent on any imageDepends on how cleanly the subject separates
ResultA regenerated frameA background plus a movable layer
Use when"They need to be over there""They need to be exactly here"

Start with the actions. They are one click and they work on frames where a cutout would struggle. Reach for pop-out when you need a specific position the presets cannot reach.

If the move looks wrong

  • Background reconstruction is smeared. The area behind the subject was detailed. Undo, and try a smaller move — or use a scene preset afterwards to give the reconstructed area something to be.
  • The face changed identity slightly. Each generative edit reinterprets. Swap your avatar back in after the move rather than before it.
  • Text is now behind the subject. Move the text layer — layers are free to reposition.
  • Enlarged and now cropped badly. Undo and use Make Bigger once rather than twice; two enlargements in a row usually cut the head.

Frequently asked questions

Where should the subject sit in a thumbnail?

Off-centre — subject in one third, text in the other. A centred subject with text on both sides fights itself.

Should I use avatar actions or pop-out?

Start with the actions: one click, reliable on any image. Use pop-out when you need a specific pixel position the presets cannot reach.

The background looks smeared after moving the subject. Why?

The area behind them was detailed and had to be reconstructed. Try a smaller move, or apply a scene preset afterwards to give the reconstructed area something to be.
