Short answer: export an MP4 with H.264 video and AAC audio, at the frame rate you recorded (30 or 60 fps), in the shape each platform shows best: 16:9 at 1920 by 1080 for YouTube and X, 4:5 or 1:1 for the LinkedIn and Instagram feeds, and 9:16 at 1080 by 1920 for TikTok, Reels and Shorts.
By platform
| Platform | Shape | Size | From the platform |
|---|---|---|---|
| YouTube | 16:9 | 1920×1080, or 3840×2160 for 4K | MP4, H.264, AAC at 48 kHz; about 8 Mbps at 1080p 30 fps and 12 Mbps at 1080p 60 fps; upload at the frame rate you recorded |
| YouTube Shorts, Reels, TikTok | 9:16 | 1080×1920 | Vertical, full screen on the phone |
| X | 16:9 or 1:1 | 1920×1080 or 1080×1080 | Length limits depend on your account type; see X's help |
| 4:5, 1:1 or 16:9 | 1080×1350, 1080×1080 or 1920×1080 | Its video ad specs recommend 4:5 for vertical and list 3 seconds to 30 minutes and up to 500 MB |

Why the shape matters more than the resolution
A screen recording is mostly small text. On a phone, a 16:9 frame shown in a vertical feed shrinks that text to almost nothing, whatever the resolution. Reframing the same recording to 9:16 or 4:5, and zooming in on each click, does far more for readability than exporting in 4K.
Frame rate
Export at the rate you recorded. 60 fps makes cursor movement and zooms look smoother; 30 fps is fine for slow walkthroughs and makes smaller files.
