Icecream Slideshow Maker vs Memento

Icecream Slideshow Maker is a Windows desktop app for making video slideshows and presentations from photos. Users can add MP3, M4A, or WAV background music, including playlists, and customize slide text by font, color, animation, background, and position. The app offers more than 25 transitions and a random-transition option. Its free version allows unlimited use and creates videos without a watermark. Output formats include WebM, MOV, AVI, and MP4, with support for 4K output. Videos can be downloaded, uploaded to YouTube, Google Drive, or Dropbox, or burned to DVD; playback can loop a set number of times. The app restores the previous project on launch and keeps projects accessible through its History panel. It is compatible with Windows 7 through 11 and Windows Server 2008. The Free plan is free. PRO is listed at $30, paid once for a lifetime license; the maker also describes a one-year license that auto-renews but can be canceled anytime.

Memento is a web and iOS service for groups preserving memories through Group Videos and Shared Albums. Organizers request video clips, collect contributions, arrange them, and customize a finished Group Video with ordering, trimming, colors, music, text, photos, and captions. A video can contain as many clips as needed and up to 60 minutes of content. Memento says a Group Video can be redone without an additional fee, while a Platinum Subscription allows downloading the result as an MP4. Shared Albums collect photos through invitations or QR codes, support review and approval, and produce customizable slideshows. Clips and completed videos are private by default, with sharing controlled through a unique viewing link. Contributors can record from smartphones, computers, or tablets. Shared Albums work on any device. The service is paid, with a three-day trial and no free plan. Shared Albums permit up to 10 photos during the trial, after which a paid subscription begins.
