Modifiche Ufficiali: Changes – v20.12.0 (21.12.2020)

La nostra squadra è lieta di annunciare Kdenlive 20.12 che porta nuove eccitanti funzioni come le transizioni su traccia singola, lo strumento per la creazione e gestione dei sottotitoli e la revisione del pannello degli effetti oltre alla solita serie di correzione di errori e miglioramenti dell’usabilità. Altro lavoro è stato fatto sull’ottimizzazione delle prestazioni (un grazie a Martin Tobias Holmedahl Sandsmark) ottenendo una timeline più reattiva, una migliore creazione delle miniature e un’apertura più rapida dei progetti.
Transizioni su traccia singola

Le tanto richieste transizioni mono traccia sono finalmente arrivate con questa versione apportando un drastico miglioramento al flusso di lavoro. La nuova funzione viene attivata selezionando una clip e premendo il tasto u or cliccando sull’icona nella barra degli strumenti della linea temporale. (Un errore noto, che verrà risolto nella prossima versione mensile, riguarda l’uso di effetti applicati sulla traccia)

La nuova sotto-titolatrice permette di aggiungere ed editare i sottotitoli direttamente sulla timeline in una traccia speciale o attraverso il pannello di sottotitolazione. È anche possibile importare (in formati SRT o ASS) ed esportare (SRT). Sashmita Raghav ha lavorato sull’implementazione di questa funzione durante l’estate come parte del GSOC.

Nota: L’interfaccia per la modifica dello stile non è ancora implementata ma puoi comunque editarlo usando le tag html come < span style = “color: #ffff00 ; ” > per, ad esempio, impostare il colore del testo su giallo.

Un errore noto riguarda l’uso dei caratteri speciali che non reagiscono in modo corretto. L’errore verrà corretto nella prossima versione mensile. Con la versione 20.12.1 verranno anche aggiunte le funzioni per nascondere e bloocare la traccia.

Effetti

Tutti gli effetti sono stati riorganizzati in modo chiaro e semplice in una nuova struttura con categorie* per un’esperienza utente migliorata. Guardando sotto il cofano, si può notare che tutti gli effetti sono stati ritoccati, per una migliorata la gestione dei parametri, e che tutti gli effetti con problemi o che non funzionavano, sono stati spostati nella categoria “Deprecated”, per la compatibilità retroattiva dei vecchi progetti, ma verranno rimossi in futuro. Se ne sconsiglia, di conseguenza, l’uso.
*La tipologia degli effetti audio dipende dal Sistema Operativo in uso

Un altro miglioramento dell’usabilità è nella possibilità di rinominare, di aggiungere ed editare la descrizione degli effetti personalizzati (grazie al contributo del nuovo membro della comunità Vivek Yadav.)

Usabilità

Oltre al miglioramento delle prestazioni, ottenuto tramite una serie di ottimizzazioni, anche la timeline ha ricevuto un incremento nell’usabilità. Le clip sulla timeline cambiano ora colore in base alle tag impostate nella finestra del progetto. (Questo funziona anche su tutte le clip all’interno di una cartella.)
