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
