If you need to load Frame Sequences to cineSync Play you just need to pick up any frame of any sequence, and it will automatically play all the files from that folder.
(You can add the file via dragging and dropping or adding the media file using the ‘Playlist’ menu.)
Once the frame is added, all the sequence files will be loaded in their entirety - from the lowest to the highest frame number.
The blue bar on the Play Controls will inform you how much of the sequence has been loaded into cineSync Play.
Please note: Currently, if the frame is part of a sequence, it is not currently possible to load it individually.
