Creating a Smooth Slideshow

This article will explain the variety of slide shows that can be created inside and outside of Doodly. It will also provide the settings and definitions for each of the settings necessary to create these slideshows.

Note: At the intermediate skill level, we all know that Doodly is one big slide show. In this article we will briefly review the basic slides with some suggestions. We will focus on the intermediate level slide shows.

Single Scene Slideshow vs. Multi-Scene Slideshow

This depends on how many images are in the slideshow. If we are working with only 5 images, a single scene slideshow is much easier to work with and maintain but if we are working with 40 images, a single scene slideshow becomes cumbersome.

A single scene slideshow is a bit easier to work with because all images are on the same scene but given the bug of layer jumping that happens in a scene within Doodly and if we are viewing this on a 2k screen with 125% zoom, like most of the world at the time of writing this article, we can only see 3 1/4 layers, a multi-scene slideshow becomes easier to maintain.

A multi-scene slideshow will allow for more control. Doodly also suffers from Scene Jumping as well so be careful of having too many scenes.

A multi-scene slideshow will do best with no more than 4 transitional images per scene. A transitional image is defined as transitioning from one image to the next without using another scene for the transition. Watch my Scene Transitions video tutorial for ideas on how to create in scene transitions.

If we are creating a multi-image slideshow like the thumbnail showed in my Bernie Sanders Memes videos where I have 9 images on a single canvas display then we can erase those with a mask and recreate this suggested as a maximum of 4 times creating a total of 40 layers including the transition layer between each image collage. Just be careful of layer jumping if you choose to have this many layers on a single scene.

What is Layer Jumping?

Watch my Doodly Bugs and Frustrations video. There is a chapter on it in that video.

What is Scene Jumping?

Watch my Pan and Zoom video for an example of Scene Jumping. It happens with the pan and zoom but the same thing happens with layers. It happens to me as I am recording the video and I decided not to edit it out.

Basic Slides

Swipe Left, Up, Right and Down. For a slideshow, swipe left and right make the most sense. Swiping up and down don’t typically do well in a slideshow. Keep about 2 to 5 seconds of time at the end of the scene and place 1 full screen image per scene when using this method.

Categories of Slide Shows (In alphabetical order)

A. Animated
B. Fading
C. Multi-image
D. Simple

There are more complex slideshows that can be created but those go into advanced skills so we are going to focus on these 4 types of slide shows.

What is an animated slideshow?

An animated slideshow include the use of GIF animation. These animation can be easily created using PowerPoint. We can import the image into PowerPoint, create our desired animated effect, export the animated GIF into Doodly and create our reveal paths and set the settings.
Depending on the image size and complexity, the typical duration is in between 1.5 seconds to 10 seconds. Most reveal paths look good with a maximum of 5 seconds but some exceptions have been made to 10 seconds. If we are using only 1 image per scene then we can keep the delay time to 0 and set the additional time at the end of the scene to desired length such as 5 seconds.

There are 3 bonus videos inside the scene transitions video tutorial. Bonus video 2 and 3 provides how to create transition effects which can be used for a smooth slideshow.

Fading Slideshow

For this to work, the imported images should be the same width and height when imported. Easily enough using 1 scene, we can disable Erase Mode, copy and paste the images and then drag the new image on top of newly pasted image. The fade to color video tutorial will teach you how to create this effect. The same principal applies as what is shown in this video. Set the reveal mode to Fade for each image. The reveal mode does not get copied when you replace the image with another image.

Multi-Image Slideshow

This uses multiple images. The duration time highly depends on how we want to reveal those images.
