Drop a cap on that GIF. Purpose-built, not bolted on.
sharex is one of the best windows utilities ever shipped. its gif export is a checkbox feature.
- sharex's gif export uses default ffmpeg. detailed content comes out dithered.
- no size cap. no auto-quality. you set fps and hope.
- great for screenshots. great for recording. underwhelming for the actual gif.
gifcap. the encode step that should follow your sharex recording. ffmpeg + gifski for per-frame palettes, drag-drop the .mkv, set a cap, ship a clean gif.
| axis | sharex (gif export) | gifcap |
|---|---|---|
| encoder | default ffmpeg, global palette | ffmpeg + gifski, per-frame palette |
| quality on detailed content | dithered, blurry | sharp at half the size |
| size cap with auto-quality | no | binary-search until it fits |
| screenshot capture | best in class | not what we do |
| screen recording | yes, deep features | not what we do |
| price | free, OSS | free tier; pro $29 lifetime |
How gifcap solves this — in detail
ShareX is one of the most respected Windows utilities ever shipped. for screenshots, region captures, upload automation, hotkeys, OCR, color pickers — it's the tool. the GIF export exists because it would be strange if it didn't, but inside the pipeline it's a checkbox: ffmpeg fires with a single global palette and whatever fps you set, and the result is whatever the result is. on color-rich or detail-heavy clips, that palette has to compromise across the whole clip, and what you get back is the characteristic dithered look every long-time ShareX user knows.
the intended pairing — and the one gifcap is designed around — is ShareX captures, gifcap encodes. record the .mkv or .mp4 with ShareX the way you already do, drag it into gifcap, set the cap, and ship. ShareX's recording subsystem is deeper than anything gifcap tries to match: monitor selection, region lock, cursor effects, audio source routing. gifcap leaves all of that to ShareX. what gifcap adds is the per-frame palette pass via gifski, and the size-cap auto-tune that binary-searches gifski's quality between 10 and 100 until the file lands at or under your target.
this isn't a "you should switch" argument. it's a "stop asking ShareX to be a GIF encoder" argument. keep ShareX for everything ShareX is great at; pass the video file to gifcap for the GIF. two tools, two responsibilities, and the GIFs that come out of that pipeline look and size like something you'd actually want to put in a README or paste into Slack.
ShareX + gifcap pairing — the spec
- ShareX capture: region, window, monitor, or fullscreen — all on hotkey, with .mkv/.mp4 output defaults.
- ShareX GIF export: default ffmpeg, single global palette, no size cap, fps is manual.
- ShareX GIF quality ceiling: acceptable for short simple clips; visibly dithered on detail-heavy screen recordings.
- Recommended pairing: ShareX records to .mkv or .mp4 → drop file into gifcap → gifcap encodes with gifski.
- gifcap accepts ShareX outputs natively: mp4, mov, mkv, webm, avi via bundled ffmpeg decode.
- gifcap engine on the encode step: ffmpeg decode + gifski per-frame palette + binary-search size cap.
- Combined workflow stays fully local — neither tool uploads the recording anywhere.
