Aspect ratio becomes the real issue when the shape of the frame must match a feed, reel, short, square post, or presentation slot.
Use this guide to pick the right ratio, then apply it in the crop tool with clearer framing decisions.
Changing aspect ratio usually means cropping, not just resizing. If the important subject is not centered, resizing alone will not help.
Resize changes dimensions. Crop changes which part of the frame survives. Aspect-ratio fixes usually start with crop.
Use crop first to get the shape right, then resize only if the destination has exact output dimensions.
Use change video aspect ratio when that is the direct fix for the real problem, rather than a side issue like format or file size.
