There are no explicit limitations for the number of images you can use in the application, only the amount of computer memory you have available limits number of sequences and images you can use in your project. During our tests, we successfully created a video of 100 thousand images that were close to 600 GB.
Short answer. As a dedicated time lapse software, Time-Lapse Tool performs better and faster. Time-Lapse Tool makes up for its cost in terms of the time it saves you in creating your time-lapse video projects.
Long answer. We decided to create the application because, although Windows Movie-Maker had similar tools, it did not support time-lapse video creation well for more demanding projects. WMM’s tools work, more or less, to create short time-lapse videos from a small number of images, but the program stalls at the image loading stage if you try to make a more extended project with thousands of images. Combining two image sequences with different fps rates is also is not supported by WMM (although it is possible with some non-obvious workarounds, which cause losses to the original image quality). Using our software, you can set up a video project of this kind in literally a few mouse clicks and start exporting the final time-lapse video almost immediately. As an additional bonus, we added a few cool effects like Miniature (Tilt Focus) and vignette.

Short answer. Time-Lapse Tool saves images to user AppData folder only on your PC.
Long answer. The program only loads original images into memory and does not save them in any form even during video export. However, it scales images down and may save these images to AppData folder for cache purposes. You may see these thumbnails in timeline view at the bottom of the main window. Program uninstall deletes even this cache. So publishing to YouTube is the only way program exposes images online.
