Why your screen recording looks blurry, and the fix

Short answer: blur comes from one of seven mismatches, recording below native resolution, display-scaling confusion, bitrate starvation on fine text, upscaling in the editor, zooming past your pixel budget, GIF's format limits, or a platform re-encode. Identify which one you're hitting and the fix is usually a single setting.

The 7 causes, in order of likelihood

1. Recording below native resolution. A 2560×1440 display captured at 1920×1080 throws away a third of your pixels before you start. Fix: capture at native size.
2. Windows display scaling. At 125%/150% scaling, apps can render at one size and capture at another. Fix: record on a 100%-scaled display when possible, or use a recorder that handles physical pixels correctly.
3. Bitrate starvation. Screen content is mostly sharp edges and small text, the hardest case for video encoders. Symptoms: text shimmer, smudged terminal fonts. Fix: raise the quality/bitrate tier; text-heavy demos deserve the highest setting.
4. Export smaller than the recording. Downscaling 1440p→720p averages pixels; 11px UI text does not survive. Fix: export at the same class you recorded, or crop instead of shrinking.
5. Zooming beyond the pixel budget. A 2× zoom shows a quarter of your pixels full-frame. From a 1080p capture that's ~960×540 stretched, soft. Fix: record at 1440p/4K if you'll zoom hard; a 4K master gives zooms room.
6. GIF limits. GIF is 256 colours per frame with dithering, it will never be video-sharp. Fix: use GIF for short UI loops, MP4 for anything with gradients or long text reads.
7. Platform re-encodes. YouTube, Slack and Teams recompress uploads. Fix: feed them the highest-quality master; never upload an already-compressed small file.

The 30-second diagnosis

Pause on a frame with small text. Sharp in the editor but blurry after export → causes 3–4. Blurry in the editor too → causes 1–2. Only blurry after upload → cause 7. Only blurry when zoomed → cause 5.

Defaults that avoid all seven

Capture native at 60fps, edit non-destructively, export MP4 at the highest quality your plan allows (Girato Free is 1080p/60; Pro unlocks 1440p/4K + Max bitrate) and let platforms downscale from strength.

Frequently asked questions

Why is my screen recording blurry when the screen looked sharp?

• Almost always a resolution or bitrate mismatch.
• Recording below the display's native resolution.
• Exporting smaller than you recorded.
• A bitrate too low for fine text.
• Fix: record native, export at the same or higher class.

More

• Give text-heavy footage a higher quality setting.

Why does it get blurrier after uploading to YouTube or Slack?

• Platforms re-encode everything.
• Upload the highest-quality master you can.
• Go higher in resolution and bitrate than feels necessary.
• That gives their re-encode headroom.
• 4K masters survive YouTube's compression far better than 1080p ones.
