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 from 100 thousand images that was close to 600 GB.
Short answer. As a dedicated time lapse software application, 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 additional bonus, we added a few cool effects like Miniature (Tilt Focus) and vignette.
