Does crediting the original creator make a Short original?
No YouTube page I read says credit makes a reused Short original. The reused content policy applies even with permission. What YouTube does ask for instead.
Crediting the creator is courteous and may be required elsewhere, but none of the YouTube pages I read treat it as what makes a reused clip original. The channel monetization policies say that if you borrow content, you need to change it significantly to make it your own, and that this applies even if you have permission from the original creator (read 2026-10-03). Credit sits below permission, so it cannot do more.
The newer recommendation change points the same way. On 2026-10-01 YouTube said voice-over of the on-screen action, minor technical edits and template-based bulk changes do not make a reused clip original; its examples of what does are your own commentary, analysis and storytelling (news report, read 2026-10-03, Search Engine Journal). Credit is not on either list.
Where does credit still help?
When the source is your own long video. YouTube's Video Clips & Shorts tool page says you will not be penalized for using your content in a clip or Short, and it tips you to add a link to the source video in the description of your clip (read 2026-10-03). That is about your own work. It is not a rule for someone else's clip.
One more caution from that tool page: it adds the source as a related video automatically, but only for Shorts made with that tool and not for private, unlisted or Made for Kids Shorts.
What counts, and what does not?
The table sorts common moves by what the two sources above say. The last column is YouTube's wording, not a prediction of how the system scores your channel.
| Move on a borrowed clip | Source says | Reading |
|---|---|---|
| Add a credit line or tag the creator | Not listed as a fix; permission does not change the rule | Courtesy, not originality |
| Get written permission | Policy applies even with permission | Does not change the requirement |
| Add a voice-over of what is on screen | Named as not original | Not enough |
| Trim, flip, resize or re-export | Minor technical edits named as not original | Not enough |
| Run one template across many clips | Template bulk changes named as not original | Not enough |
| Comment on the clip, analyse it, tell a story around it | Named as the kind of value that counts | The route YouTube describes |
What can Sume change about this?
Sume cannot turn another creator's footage into yours. What it can do is produce footage and sound that are yours to begin with, such as a generated scene or an avatar presenter, and assemble them with Timeline 1.0. The question YouTube asks is whether your channel adds something, so write the commentary first and build the visuals after. The related posts cover voice-overs, bulk templates and reference clips.
