Video Slideshow¶
The Video Slideshow tool allows creation of a movie from a list of photos. The generated file can be played on a video player or a TV screen. Images are presented one by one with visual effects if you need them. This tool can also be used to create a time-lapse animation from shots taken with an intervalometer.
Select the images that you want to encode as video and go to a wizard dialog will open up as below.
The Video Slideshow Wizard Welcome Page¶
This page allows you to select the contents to export using one of two methods, either from the current items selection, or from a list of albums. With the Albums selection mode you can generate a video slideshow from album contents. Just check the respective albums displayed in the hierarchical list. Use the next three tabs Tags, Searches, and Labels to refine your selection using tags, labels, or previous search results in digiKam.
If you use the Images selection mode only the previous selection of items from the Icon-View will be processed and listed on this page as a flat list.

Press the Next button to display all the video settings used to encode the slideshow. The parameters are:
Number of Frames by Image: The number of frames generated of one image to encode in the video stream. This defines the time of one image will be present statically on screen. If you set an Effect While Displaying Images, this one will be rendered with this number of frames.
Video Standard: This is the video norm to use while encoding media, as PAL - 25 FPS or NTSC - 29 FPS (FPS: Frame Per Seconds).
Video Type: This is the video resolution to use while encoding media. Images are resized accordingly. Take care that high resolution will require more resources to encode and use more space on your disk.
Video bit Rate: This is the bandwidth used to encode video. A low value means poor quality, and a high value means good quality. Be aware that high-bit-rate video will require more space on your disk.
Video Codec: This is the standard video encoding method to make the media.
Effect While Displaying Image: Select the visual effects to apply on an image while Number of Frames by Image.
Transition Between Images: Select the visual effect to apply as a transition outside the Number of Frames by Image.
The tool on the bottom of this view calculates the delay for each image on the screen including applied visual effects, and the total duration of the slideshow.
