How to make a reaction Short that counts as original value (Oct 2026)

A reaction Short counts as original only if the commentary is yours: your analysis, your argument, your story around the clip. YouTube's October 2026 recommendation change says voice-over that only describes what is happening on screen, minor technical edits and template-based bulk changes do not make a reused clip original. Sume can cut the quoted moment, burn your commentary as captions and assemble the result, but it cannot supply the opinion. That part has to come from you.

The change was announced on 2026-10-01 by YouTube Creator Liaison Rene Ritchie, as reported by Search Engine Journal (read 2026-10-03). It affects recommendations; monetization stays under YouTube's existing reused-content rules, which say taking someone else's content with minimal changes is a violation, even with the original creator's permission (read 2026-10-03). Whether you have the right to use the source clip at all is a separate question this post does not answer.

What a reaction Short needs to add

Treat the quoted clip as evidence, not as the video. A structure that keeps your take in front:

• Open on your own hook line before any source footage plays.
• Quote only the few seconds your point depends on, then stop and make the point.
• Put your analysis in the second half: why the moment matters, what the clip leaves out, what you would do differently.
• Close with a takeaway that could not be written by someone who had not watched the clip carefully.

Where Sume fits

Each mechanical step is one documented job, and none of them creates the commentary:

Build it in order

Upload or import the source clip so it lives on your workspace's media.sume.com, then trim the quote with a start and a duration. Caption jobs take a public HTTPS video URL, and the Sume artifact URL from the trim result qualifies. Burn your commentary with cues (each cue is text, start, end) so the caption job does not try to transcribe a clip that may be silent, which would otherwise fail as caption_no_speech.

If you recorded your own take on your phone, that recording is the audio spine in Timeline 1.0 and the quoted trim sits in a video slot over it. Prices above are the documented rates; confirm them in GET /v1/catalog before a large run, per the Video captions and Video trim pages.

Limits to know

Timeline compose takes one still and one video, not two videos, so a picture-in-picture of your face over the quote needs your recording to be the base clip. Voice-over alone is the pattern YouTube named as insufficient, so a Sume TTS narration reading a summary over someone else's footage is the weakest version of this Short. If the Short would still work with the quoted clip removed, you are on the right side of the line.
