Rilasciato Kdenlive 26.08.0

Lunedì, 31 Agosto 2026 | Farid Abdelnour

Siamo lieti di annunciare il rilascio estivo di Kdenlive 26.08. Proseguendo il lavoro iniziato con la versione precedente, la squadra principale si è concentrata principalmente sulla stabilità, correggendo bug e crash e apportando al contempo numerosi miglioramenti sotto il cofano.

Questa versione include 11 correzioni di bug, oltre a miglioramenti allo stack di operazioni di annullamento e ripristino per le composizioni e la creazione di sequenze. Sono stati inoltre effettuati interventi per modernizzare il codice del caricatore QML per le clip e le composizioni.

La maggior parte delle novità e dei miglioramenti, tutti ingegnosi e accattivanti, presenti in questa versione sono stati realizzati da nuovi collaboratori! Sembra che questa sia ormai diventata una tradizione nel 2026, e non potremmo esserne più felici.

Novità

Linea temporale

Creazione automatica delle tracce

È stata aggiunta una funzionalità che permette di creare automaticamente delle tracce audio all'aggiunta di una clip alla linea temporale, se non ce ne siano abbastanza. Implementata da Vineet Tiwari.

Riorganizzare le tracce

È stata aggiunta la tanto attesa funzione che consente di riorganizzare le tracce. Implementata da Vineet Tiwari.

Marcatori negli spazi vuoti

È stata aggiunta l'opzione per inserire dei marcatori negli spazi vuoti tra le clip della linea temporale. Implementata da Yash Bavadiya.

Aggancio dell'indicatore di riproduzione al trascinamento

Premendo ALT e trascinando il cursore temporale (indicatore di riproduzione) sul righello della linea temporale, questo ora si aggancia ai punti di aggancio vicini, ad esempio i bordi delle clip, le guide, i marcatori e i punti di attacco e di stacco delle zone. Implementato da Yash Bavadiya.

Copia la selezione in una nuova sequenza

Funziona in modo simile alla funzione “Crea sequenza dalla selezione”, tranne che non rimuove le clip dalla sequenza originale, né le sostituisce con la nuova clip della sequenza. Implementata da Vineet Tiwari.

Configurazione delle clip di colore

È stata aggiunta un'opzione per configurare i colori per i tipi di clip video, audio, immagine e presentazione.

Indicatore di riproduzione/Ingrandimento del mouse

È stato aggiunto un pulsante nella barra di stato per passare dall'ingrandimento alla posizione del cursore del mouse a quello dell'indicatore di riproduzione. L'implementazione è stata eseguita da the mrfantastic.

Cambio della velocità a più clip

È stata aggiunta la possibilità di modificare la velocità di riproduzione di più clip contemporaneamente, sia trascinandole direttamente nella linea temporale tenendo premuto il tasto Ctrl, sia utilizzando lo strumento Velocità della clip. Implementato da Vineet Tiwari.

Editor dei titoli

Aggancio

È stata aggiunta la funzione di aggancio nell'Editor dei titoli. Implementata da chocolateimage.

Angoli arrotondati

I rettangoli ora possono avere gli angoli arrotondati. Da notare anche la possibilità di trascinare la casella di selezione per modificare il raggio. Implementato da chocolateimage.

Copia/Incolla

È stata aggiunta la possibilità di copiare e incollare gli elementi nella titolatrice. Implementata da chocolateimage.

Sostituzione automatica delle clip

È stata aggiunta l'opzione per sostituire automaticamente una clip titolatrice nella linea temporale con la nuova in fase di modifica. Implementata da Eduardo Guedes.

Varie

Attivare l'audio in solo

È stata aggiunta la possibilità di attivare l'audio in solo in modalità additiva nel mixer audio facendo clic tenendo premuto il tasto Maiusc. Implementata da Patrick Williamson.

Ancoraggio di rotazione regolabile

È stata aggiunta la possibilità di impostare il punto di rotazione nell'effetto Trasformazione. Implementato da Jean Baptiste Mardelle.

Altre modifiche notevoli

Sono stati aggiornati gli effetti con testo (Testo GPS, Testo dinamico e Timer) per consentire un maggior numero di proprietà dei caratteri. Implementato da Bernd Jordan.
La maschera alfa rettangolare è ora animabile. Implementato da Jean Baptiste Mardelle.
È stata aggiunta la possibilità di utilizzare delle espressioni matematiche nei valori degli effetti. Implementato da Jean Baptiste Mardelle.
Gli effetti Disegna un riquadro e Rimuovi logo utilizzano la nuova funzionalità per disegnare un rettangolo direttamente sullo schermo. Implementato da Jean Baptiste Mardelle.
È stata aggiunta l'effetto frei0r Miglioramento del colore. Implementato da Bernd Jordan.
È stata aggiunta l'opzione per aggiungere il video generato al contenitore del progetto nell'oggetto Genera. Implementato da Jaimukund Bhan.
Montaggio multi camera: è stata aggiunta la funzionalità per inserire le clip nella linea temporale utilizzando il codice temporale della clip dai relativi metadati (se presenti). Implementato da Jaimukund Bhan.
C'è la possibilità di aprire file video, audio e immagine da gestori di file o da ambienti a riga di comando con Kdenlive. Implementato da Yash Bavadiya.
È stato aggiunto il supporto webp per le sequenze di immagini. Implementato da Farid Abdelnour.
