Although Snapizzi doesn't edit EXIF data, we do utilize it during sorting. If your software outputs JPEGs containing new EXIF data, you must process all of the image files (including camera cards) together using the same process before uploading to Snapizzi. Ensure that the time on your camera is set properly so timestamps are accurate in the image file EXIF data.
The main thing to be aware of is that you don't change EXIF data for only part of your images since that is how Snapizzi can tell multi-camera Projects apart and keep images separate. For instance, if you edit some of your images and they have different EXIF data than others from the same camera, Snapizzi will think they are from two cameras and it won't sort properly.
Snapizzi will automatically alert you if there are any issues with your EXIF data. This also applies if you're doing greenscreen or building composite images for your Project.
If your workflow includes renaming your image files prior to uploading, be sure that your filenames include leading zeros equal to the highest number in the sequence—e.g., 0001 - 9999 rather than 1 - 9999. Snapizzi can rename your image files for you if needed.
