Kdenlive 26.08.0 uitgegeven
Met genoegen kondigen we de zomeruitgave van Kdenlive 26.08 aan. Voortbouwend op het werk aan de vorige versie heeft het kernteam zich voornamelijk gericht op stabiliteit: het oplossen van bugs en crashes en het doorvoeren van tal van verbeteringen onder de motorkap.
Deze uitgave bevat 11 oplossingen voor crashes en verbeteringen aan de ongedaan maken/opnieuw-stack voor composities en het aanmaken van sequenties. Daarnaast is er gewerkt aan het moderniseren van de codebasis in de QML-lader voor clips en composities.
Het merendeel van de nieuwe, handige en fraaie toevoegingen en verbeteringen in deze uitgave is afkomstig van nieuwe bijdragers! Dit lijkt in 2026 een traditie te zijn geworden, en daar zijn we ontzettend blij mee.
Highlights
Tijdlijn
Automatisch aanmaken van een track
Functionaliteit toegevoegd om automatisch audiosporen aan te maken bij het toevoegen van een clip aan de tijdlijn, voor het geval er onvoldoende sporen zijn. Geïmplementeerd door Vineet Tiwari.

Selectie kopiëren tot nieuwe sequentie
Het werkt vergelijkbaar met "Sequentie maken van selectie", met dit verschil dat de clips niet uit de oorspronkelijke sequentie worden verwijderd en vervangen door de nieuwe sequentie-clip. Geïmplementeerd door Vineet Tiwari.
