How to Convert Videos to Slow Motion?

TL;DR:

You can convert normal-speed videos into slow-motion across any operating system using built-in native tools like Microsoft Photos and iMovie, third-party editors like Wondershare Filmora and CapCut, or size-limited web converters.
    ● Windows 10 and 11 users can apply native Slow or Super-Slow effects via the Edit & Create menu in the Photos App, while Mac users can utilize iMovie to change the speed drop-down to Slow and extend the video duration.
    ● When using dedicated editors like Wondershare Filmora or the CapCut mobile app, you must split the clip to isolate a specific slow-motion segment and manually detach or mute the audio track first to prevent distorted playback sounds.
    ● Browser tools like Online Converter permanently export slow-motion files but enforce a strict 200MB maximum upload limit, whereas Linux users utilizing VLC Media Player are only adjusting temporary playback speeds rather than converting the actual file.
