Aspect Ratios and Resolutions
Choose the ratio that fits the viewing context. The best twitter video tool will handle these for you automatically.
Vertical (9:16): Best for immersive mobile viewing. Use 1080 × 1920.
Square (1:1): Great for feed versatility and maintaining text legibility. Use 1200 × 1200 or 1080 × 1080.
Landscape (16:9): Best for tutorials or demos. Use 1920 × 1080.
Phase 2: Winning the Creative Game
Raw technical specs are only half the battle. Your video must hold attention in a fast-scrolling feed.
The Hook is Everything
Front-load the hook in the first 1 to 2 seconds. This is the single most important rule for engagement.
Keep motion density high: quick cuts, clear subject framing, and progressive visual reveals. This is how you Create Viral Videos for Twitter.
Encoding Settings That Hold Up
When exporting from your twitter video tool, use these pragmatic settings to minimize quality loss:
MP4 container with H.264 High Profile.
Use a Constant Frame Rate (CFR).
Set your Keyframe interval (GOP) to approximately 2 seconds (≈ 60 frames at 30 fps). This improves seek and playback stability.
Phase 3: Captions, Compliance, and Scale
Captions aren't just for accessibility; they’re a necessity, as most viewers watch with sound off.
Closed Captions via .SRT
X supports attaching a single SRT file to your video upload on the web. This is the professional, accessible way to manage captions.
Upload your video, then select "Upload caption file (.srt)". See the official steps in X Help - Upload caption (.srt) file.
Practical SRT Tips: Keep line length short (around 32 to 40 characters per line) and break lines at natural phrase boundaries. Avoid crowding the bottom edge to prevent UI overlaps.
Accessibility and Alt Text
If your post uses a thumbnail or companion images, always add detailed Alt Text.
Ensure on-screen text uses high-contrast colors and strong font weight, as re-compression can degrade legibility. Respect safe margins in 9:16 format, keeping critical elements away from the top and bottom 10%.
