A comment reply overlay is a graphic of a viewer's comment placed over the video that answers it: a rounded bubble with the commenter's avatar, a small line such as “Reply to maya.codes's comment” and the comment itself. Short-video apps add one when you reply to a comment with a video. Editors rebuild it when they cut the video in another program, post it on a second platform, or want the comment to appear at a moment of their choosing.
This maker draws one in two styles. Reply sticker is the speech bubble: an initials avatar, the small line, and the comment in bold. Comment row is the comment as it reads in a comment section, with the name, how long ago it was posted, and a like that lands while its count ticks up. Both come on a light or a dark card, pop in, stay as long as you set, and can pop back out.
Quote the comment as it was written, and set the background to green before you download so the sticker keys out cleanly over your footage. In a 9:16 frame the Top, Bottom and Right positions stay clear of where apps draw their own tabs, buttons and captions.
