Subtitles and Slides sync option #6

Closed pk1130 closed 3 years ago

pk1130 commented 3 years ago

@Trekky12 Hi! I am using the cli version of this app as back-end for my use case. I see there is an option to explicitly sync videos and background music, but there seems to be no such option to explicitly sync slides with their corresponding titles/subtitles. Is there a way I can ensure that if slide 1 runs for 5 seconds, then its corresponding title also run for 5 seconds?

Thanks for making such a useful app/repository!

Thank you for the kind message 😊

Actually the subtitles should always start at the end of the transition-in: https://github.com/Trekky12/kburns-slideshow/blob/5883ab585ad08ec4ef020cb131d70a43cbc671ed/slideshow/SlideManager.py#L854-L855 and end on the end of the transition-out: https://github.com/Trekky12/kburns-slideshow/blob/5883ab585ad08ec4ef020cb131d70a43cbc671ed/slideshow/SlideManager.py#L858-L859

With titles you mean the black overlay title like in the demo ("Demo Slideshow"), right? image

At the moment it is indeed not possible to sync the titles duration to the slides duration. Do you want to sync all titles to the corresponding slide durations?

Hey @pk1130, I've added a cli parameter --sync-titles-to-slides in the development branch. Is this what you need?

@pk1130 can this issue be closed?
