Most-replayed is a real signal, used carefully
YouTube publishes a most-replayed graph for many videos, an aggregate of where thousands of people scrubbed back. Where it exists, Clips Kitty reads it and lets the very top of that curve nudge a moment up the ranking.
Made for talking-head content
Podcasts and interviews
Podcast mode handles multi-camera footage: each shot gets its own steady crop centred on whoever is talking, so cuts land on a face with no panning.
Tutorials and commentary
Scoring leans on what is said, and clips snap to sentence boundaries so a Short never opens mid-word.
Your own back catalogue
Point it at videos you already published and mine them for Shorts. Or import a local file to cut before you publish anything at all.
One thing worth knowing about codecs
YouTube serves much of its catalogue in AV1, which almost no consumer GPU decodes in hardware. Left alone, that made processing take roughly twice as long, because every analysis pass and every render paying for software decoding.
Clips Kitty asks for H.264 instead, and converts once up front if it ends up with something slow. You do not have to know any of this; it is here because "why is YouTube slower than Twitch" is a fair question with a real answer.
Posting the Shorts back
Shorts need nothing special on the way out: no separate mode and no hashtag. YouTube decides a video is a Short from its shape and length by itself. Export the clips and upload them however you normally would.
If uploading a dozen by hand is the part you dread, Clips Kitty can post them for you. Write the title once and a clip goes to YouTube, TikTok, Instagram, Facebook, X, Threads, LinkedIn, Pinterest and Bluesky together, or a whole batch goes out spread over a few days so nothing looks like spam. It runs through WoopSocial or Upload-Post on your own account, which is the one part of the app that is not local, and it stays off until you switch it on.
