thearchivist.funStitch makes the reply part of the video
A built-in excerpt tool joined an existing clip to a newly recorded response.
Context and provenance
TikTok introduced Stitch on September 3, 2020. The launch described a way to select up to five seconds from another user's video and combine that excerpt with a new recording. Unlike a simultaneous side-by-side composition, the excerpt can establish a premise before the next creator responds, completes a story, or changes its direction. The announced system also included creator settings controlling availability and attribution linking back to the original video. These details matter historically because remix was being formalized as a platform feature with visible source relationships. The creative possibilities came partly from sequencing: the selected beginning shapes how an audience understands everything that follows.
Why it matters
An excerpt is an editorial decision. It can invite a useful response or alter the context of the original, so preserving a source link helps viewers understand the relationship between the selected fragment and the complete contribution.
