What's New in Slow

2.17.0

October 5, 2026

NEW: Smooth Slow Motion. Slow your videos right down without the stutter: Video Speed now creates the in-between frames, so slow motion plays smoothly, as if it had been filmed that way. Try it free on 3 videos. Plus more reliable saving, and bug fixes and polish. We'd love to hear what you think.

4 anstatt 5 Sterne

4 Sterne desegen, weil es intuitiv und einfach zu bedienen ist, damit auch wir Älteren damit zurechtkommen, die noch an Schemata wie "wenn -rot und in einiger Entfernung = warm-; dann -rot und nahe dran = heiß-" gewohnt sind. Leider ist es keine gut gerechnete, echte Zeitlupe, wo Bilder zusätzlich hineinkopiert werden, um die Langsamkeit zu erzeugen.
