Are the trial versions limited in time or features?
The trial versions are not limited in time nor in features, but the results will be watermarked, and certain files encrypted.
The few limitations in the trial versions are:
Autopano Pro/Giga:
Rendered images are watermarked.
Export to Panotools: the control points are only partially exported.
Saving the project (as a .pano): Control points and Masking points are not saved in the demo projects, only the placement of the images is retained.
Neutralhazer Light is limited to 3 images (Autopano Giga).
Panotour Std/Pro:
Built virtual tours are watermarked.
Livepano videos are watermarked.
XML is crypted, so you cannot edit the tour's generated files afterwards (Panotour Pro).
Autopano Video Std/Pro:
Rendered videos are watermarked.
Video output is limited to 30 seconds.
Neutralhazer:
Images are watermarked.
