Sized for the timeline
Export 16:9 (1920×1080), square 1:1 or vertical 9:16 — X is the one platform where landscape still shines.
For X creators
Turn long videos into viral X posts
Video posts on X get replayed, quoted and shared. ClipFox finds the moments worth posting, exports them in the shape X shows best, and writes a post under 280 characters — plus a full thread and a quote-post idea.
Why ClipFox
Fits the 2:20 limit
Clips are trimmed to X's 140-second limit automatically; the sweet spot is 15–45 seconds.
Post + thread + quote
AI writes a post under 280 characters with 1–2 hashtags, a 3–5 post thread (hook → context → payoff → CTA) and a quote-post idea.
Every other platform too
Tick TikTok, Reels, Shorts, Facebook, Snapchat and LinkedIn in the same export — it still counts as one.
