How to Turn Gameplay Recordings into TikTok Clips

To turn gameplay recordings into TikTok-ready clips, trim your footage to short, vertical videos with captions - Vidulk's AI Clipper automates these steps for you.

Gameplay recording to TikTok Clips: How to Make Short

Step 1: Capture Your Gameplay Footage

Record your gameplay using built-in tools or popular apps. On PC, use Medal or OBS. On consoles, use Xbox/PlayStation capture features. On mobile, use your device's screen recording. For best results, capture at high resolution (1080p or higher) and include your face-cam or commentary if desired.

Step 2: Understand TikTok Clip Requirements

Length: Up to 60 minutes per upload (feature rolling out; most users focus on 15-90 second clips for engagement).
Aspect Ratio: 9:16 vertical is recommended. TikTok also supports 1:1 and 16:9, but vertical displays best in-feed.
Resolution: Standard is 1080x1920 (vertical). TikTok accepts 360-4096 px on each side, but 1080x1920 is optimal for quality and compatibility.
Captions: TikTok has built-in auto captions, but adding captions before upload can improve clarity and accessibility.

Step 3: Clip, Resize, and Caption with Vidulk's AI Clipper

Vidulk's free AI Clipper (iOS and Android) streamlines the process:

Upload or paste your long gameplay video (from any source).
The AI scans your footage, finds the best moments - like clutch plays, fails, or reactions - and extracts short highlights.
It automatically resizes clips to vertical (9:16), adds captions, and prepares them for TikTok's specs.
Export your finished clips, ready to upload to TikTok or other short-form platforms.

Step 4: Post to TikTok

Upload your exported clips to TikTok. Double-check that the aspect ratio is vertical and captions are legible. Use TikTok’s edit screen to adjust auto captions if needed, add hashtags, and publish. For best engagement, keep clips concise and focused on exciting moments.

Vidulk's AI clipper (free to start, iOS + Android) finds the best moments in a long video and exports captioned vertical clips sized for the destination.
