Shorts Studio — game zone
Auto-crop LoL highlights to viral shorts in your browser
Shorts Studio — Turn LoL VODs into 9:16 shorts, automatically Runs entirely in your browser — no uploads, no limits, free. Automatically detects kills, deaths, and multikills in your League of Legends VOD, picks the best moments, and lets you frame, and score them into ready-to-post vertical clips for TikTok, Reels, and YouTube Shorts.
Hey Product Hunt 👋
I built this because clipping LoL VODs into shorts was eating way too much of my time. Scrubbing through 20-30 minutes of footage, manually finding kills, then re-editing each clip for vertical format.
The whole thing runs 100% in your browser. Nothing touches a server, so it's free with no clip limits. That also meant rebuilding video decoding/encoding and HUD scanning to run entirely client-side with WebCodecs and WebGPU.
One decision I'm still a little proud of: I tried auto-detecting the exact moment for effects (screen shake on a kill, etc.) using the Riot API and audio correlation, and it kept confidently lying to me. It'd claim "9/9 events matched" while being off by 12 seconds. Turns out Riot's API doesn't even expose cast timestamps. A human can point at the right frame in under a second, so instead of chasing that automation, I just made manual placement fast (single keypress, frame-by-frame nudging) and left it at that.
Right now it's LoL-only, but if this resonates I'd love to expand the same engine to other games (Valorant, Overwatch, etc. are on my radar).
Curious what you all think, especially if you clip VODs for TikTok/Reels/Shorts today. What's the most annoying part of your current workflow?
