How to Turn Gameplay Recordings into X (Twitter) Clips
To share your best gameplay moments on X (Twitter), you need to trim, resize, and caption your recording for the platform’s specs. Here’s how to do it fast, with or without automation.

Step 1: Get Your Gameplay Recording Off Your Device
Export your gameplay clip from Medal, Xbox/PlayStation capture, or your phone’s screen recorder. Save the file to your computer or mobile device. If you want to include your reactions, use a face-cam overlay or record your commentary separately.
Step 2: Edit and Resize for X (Twitter) Specs
- Length: Non-Premium users: max 2:20 (140 seconds). Premium: up to 4 hours (with resolution limits).
- Aspect Ratio: X recommends 16:9 (landscape or portrait) or 1:1 (square). Acceptable range is 1:3 to 3:1.
- Resolution: 1280x720 (landscape), 720x1280 (portrait), or 720x720 (square) are recommended.
Use video editing software or mobile apps to trim your gameplay to the best moments and crop or resize for vertical (portrait) or square formats. Add face-cam, overlays, or captions for context if needed.
Step 3: Captioning and Subtitles
X allows attaching SRT subtitle files to videos on the web, but does not auto-generate captions. To boost engagement, add burned-in (hardcoded) captions directly onto your video. Many editing apps support this, or you can use AI tools for automatic captioning.
Step 4: How Vidulk Automates the Process
Vidulk’s AI Clipper (iOS & Android) streamlines this workflow. Paste your long gameplay video (from any source), and the app finds the best highlights, trims to under 2:20, converts to vertical (9:16) or square (1:1), and adds burned-in captions. Export your finished clip, ready for X upload. This saves time and ensures your video meets X’s specs.
Step 5: Uploading to X (Twitter)
- Log into X on web or mobile.
- Click the media upload button and select your edited clip.
- Attach SRT subtitles if desired (web only).
- Add a caption and post.
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.
