- Raise the bitrate.
Settings → Recording quality: 8–12 Mbps for most laptops, 16–32 Mbps for strong computers or Retina screens, up to 80 Mbps for very large screens.
- Choose 60 fps
for scrolling and animations (Settings → Capture smoothness).
- Size the window sensibly.
A 1280–1600 px wide browser window gives readable text; a huge 4K window makes text tiny when viewed on phones.
- Zoom the page, not the video.
Use Chrome's zoom (Ctrl++) to make text bigger before recording.
- Use live zoom or Smart Edit
for details.
On the viewer's side
Export MP4 at 60 fps, upload the original file (not a re-compressed copy), and pick the HD option when sharing.
