Getting started
- Drop one or more videos onto the window, or choose File › Add Videos.
- Choose how many screenshots you want with the button at the right of the toolbar: one every few seconds, or a set number.
- Click a screenshot to leave it out, then Export, or Create Share Image to put them on one sheet.
Questions
Which videos can Kvikkshot open?
Anything macOS can play: MP4, MOV, M4V and the H.264, HEVC and ProRes inside them. MKV, AVI and WebM files need converting first, for example with HandBrake.
What is the difference between fast and precise?
Fast mode takes the nearest keyframe to each point, which is why even long 4K videos take seconds. Turn on Precise Frames when you need the exact moment; it decodes more and is slower.
Some screenshots say they couldn't be read.
The video is damaged at those points, or it is still being copied or downloaded. Kvikkshot retries every missing frame with a fresh decoder before it gives up, and tells you how many are missing instead of stopping.
Where do exported screenshots go?
Export asks for a folder and creates a “… Screenshots” folder inside it for each video. To skip the question, choose a default folder in Settings.
Are my screenshots stored anywhere?
Only in Kvikkshot's private temporary folder while you work. It is emptied when you go back to the start screen, when you quit, and at the next launch if Kvikkshot was quit unexpectedly.
How do I update?
The Mac App Store version updates through the App Store. In the downloaded version, choose Help › Check for a New Version; it opens this website in your browser, because Kvikkshot itself never goes online.
How do I uninstall it?
Drag Kvikkshot from Applications to the Bin. Its settings are in ~/Library/Containers/com.feiyangtang.Kvikkshot, which you can delete too.
Privacy policy
Kvikkshot collects no data. It has no network access: the App Sandbox does not let it connect to the internet. There are no accounts, analytics, telemetry, crash reporting, advertising or update checks, and no third-party code.
It reads the videos you open, keeps the screenshots it makes in its own temporary folder while you work, and writes files only where you export or save them. It remembers your settings, the last folder you exported to and, if you choose one, your default export folder. All of this stays on your Mac.
Links in the Help menu open in your browser, outside Kvikkshot. “Check for a New Version” tells this page which version you have, so it can say whether a newer one exists.
Kvikkshot is suitable for all ages and collects nothing from anyone, including children. Questions about privacy: support@tang-spark.no.
Terms
Kvikkshot is free. You may use it for personal and commercial work, and the screenshots and share images you make are yours.
It is provided as is, without warranty. TangSpark is not liable for loss of data or other damages from using it, as far as the law allows. Only process videos you have the right to use.
Mac App Store downloads are also covered by Apple's standard licence agreement.
