Currently video playback will not work, there are licensing issues to be resolved. If when adding a video it is not shown in the correct orientation enter edit mode and use the rotate left/right button to correct its rotation before building the album.
jAlbum's video editor lets you trim the beginning and end of video files. You can also select what frame to use to represent your video in the album. jAlbum supports 164 video formats and converts them to mp4 format for use by most web browsers. Additional settings for controlling the quality and resolution, or for advanced users full custom control, can be found under Settings/Video
The figure to the right shows a grayed out play button, this is to indicate the file is a video, it is not a play button for previewing your video. Scrub bars 1+2 and 3 only appear if video support has been enabled in Preferences/Advanced>Video support.
Adjusting the position of the green circle (1) sets the start point, and the red circle (2) sets the end point, of the video in your album. The white slider (3) sets the frame of the video to be used as the thumbnail. The default thumbnail is from a frame one second from the start. For all three, click and drag slowly and the video preview will update to show the frame selected. Note: the time boxes do not update. They just show the length of your original video.
You can, depending on the skin, of course, enter a title and comment (caption), as you would for any other file type. The other editing tools here only affect thumbnails and slide images, not the actual video.
MP4 format videos can be opened in a pop-up window. Hover over the thumbnail and select 'Open' from the 'More' menu or simply double-click the thumbnail. The controls now available are:
If you previously had used .thm files you will need to force reprocessing of thumbnails, the easiest way is to delete the album (output) thumbnail for each video using this method.
