Every streamer knows: the content conveyor must not stop! But how do you package hours of “raw footage” into dynamic Shorts for YouTube, TikTok, or Reels? This guide will help you cut streams without losing quality, turning long recordings into viral highlights. We’ll break down how long cutting takes, what moments to choose, and how to optimize the process so your content gets monetized.
To turn existing footage into a YouTube Short, choose a bright moment that is self-contained. Shorten it to 3 minutes or less, crop vertically (9:16) so the action remains in focus. Check the audio and subtitles, then upload.
YouTube treats any square or vertical video up to 3 minutes long as a Short, so the shape and length of your export determine most of the outcome.
Choosing a moment for Shorts: from clip to stream
The amount of work depends on your source. A 40-second clip you’ve already trimmed only requires reframing and refinement.
A four-hour stream recording requires finding the right moment first, and this search is usually the slowest part of the process. If you already know which moment you want to use, whether it’s gameplay footage or a saved clip from a stream, it simplifies the task.
Cutting tools: YouTube Remix and third-party services
Cutting Shorts from public YouTube videos
If the source is a long video already published on your channel, YouTube offers a quick path. On the video’s watch page in the YouTube app, tap “Remix,” then “Edit into a Short,” and select up to 60 seconds.
YouTube’s help page limits this feature to your own public long uploads. Private videos, unlisted videos, and videos with third-party copyright claims cannot be used, and the finished Short will link back to the original.
Cutting Shorts from long stream recordings: Eklipse AI
With a long recording, editing is the easy part. Finding 30 seconds worthy of publication in a three-hour stream is the real work.
For gaming streams, Eklipse turns long videos into short clips by scanning VODs for in-game signals, microphone volume spikes, and chat activity. You can connect your Twitch, YouTube, Kick, or Facebook account for recordings to automatically upload after each stream, import a public YouTube video by URL, or upload an MP4.
“Eklipse AI is your personal content pipeline. It doesn’t just cut, it finds gold in your hour-long streams. It’s not just a tool, it’s a solution for mass cutting 100+ clips and automatic stream cutting.”
Each method has its limitations: most streams are processed in minutes, though a four-hour VOD can take up to an hour. Treat the results as a preliminary list.
Eklipse’s own help references call AI selection a starting point, and you can adjust the start and end points of each clip in Eklipse Studio before exporting. Creating and exporting clips requires an Eklipse premium plan.
Optimizing for vertical viewing: cropping and subtitles
Cropping a widescreen game to a vertical format discards about two-thirds of the image, so cropping must be intentional. If you already have a clip and need help with vertical editing, Eklipse’s YouTube Shorts editing workflow includes this.
Eklipse Studio offers vertical layout templates, a layout with a webcam and game feed, cropping, text, and automatic subtitles that you can edit. AI Edit accepts a Twitch or Kick clip URL, a clip from your AI Highlights library, or an MP4 upload up to 1GB if the clip is between 15 seconds and 3 minutes long, and reframes it vertically with subtitles.
Free Eklipse AI Reframe tool
For a single clip without an account, the free browser-based Eklipse AI Reframe tool accepts a Twitch clip URL, a direct .mp4 or .webm link, or an MP4, WEBM, or MOV upload, and exports in 9:16, 4:5, or 1:1 formats. It cannot read YouTube links, so download your footage first if it’s there.
Uploading and checking Shorts
From a computer, sign in to YouTube Studio, click “Create,” then “Upload videos,” and select your file. Before publishing, go through this checklist:
Is it trimmed to 3 minutes or less? Yes.
Is it cropped to square or vertical? Yes.
Is the audio and subtitles checked? Yes.
Frequently Asked Questions
Can you make a YouTube Short from a long video?
Yes. Trim a segment to 3 minutes or less, crop it to square or vertical, and upload. If the long video is public on your own channel, YouTube’s “Edit into a Short” option lets you select up to 60 seconds directly in the app, and the Short will link to the original.
Can you make Shorts from a live stream recording?
Yes, if you have the recording as a file or a supported VOD. Trim each highlight to 3 minutes or less and reframe it vertically. YouTube’s help pages for “Edit into a Short” and Studio clips don’t specify if past live streams are supported, so exporting the recording and editing it yourself is a reliable path.
Should you crop videos to 9:16 before uploading?
Yes, if you want it to completely fill the phone screen. YouTube accepts square video as a Short, but only 9:16 fills the vertical player. Crop it yourself to choose what stays in the frame. This is important for cutting for TikTok from Twitch and other platforms.
What is the difference between turning a long video into clips and editing a clip for Shorts?
Turning a long video into clips means finding moments worth publishing. Editing a clip for Shorts begins after selecting a moment and includes vertical cropping, trimming, subtitles, and export. Long recordings require both steps; a clip you’ve already cut only requires the second.
