How to Turn a YouTube Video Into Shorts

Turn a longer YouTube video into Shorts-ready vertical clips with Crop & Resize and Trim & Cut in RenderSnap.

If you want to turn one YouTube video into Shorts, start by pulling out the section you want, then switch it to a vertical Shorts format. In RenderSnap, the fastest path is Crop & Resize plus Trim & Cut.

Resize your clip for YouTube Shorts

Convert landscape or square footage to 9:16 vertical — the format Shorts requires.

How To Turn A Video Into A Short

Pick one moment from the longer video
Use Trim & Cut if you want to keep one section from a full YouTube video instead of the whole thing.
Open Crop & Resize
Upload the clip and choose the Shorts-friendly vertical format.
Choose the framing mode
Blur background is the easiest fix if you want to preserve the full original frame, while Crop to fill gives a more native full-screen look.
Render the final Short
Download the vertical version and repeat the same process for the next moment if you want multiple Shorts from one source video.

Best tool order

One long YouTube video: start with Trim & Cut
Need it to fit Shorts: then use Crop & Resize
Need a lighter final file: finish with Compress

Good to know

RenderSnap's quick trim tool keeps one continuous section at a time. So if you want multiple Shorts from one long video, make one clip, export it, then repeat for the next highlight.

A simple Shorts target

For YouTube Shorts, the clean target is:

9:16 vertical
1080 × 1920 px
