MP4tools is technically trialware, though in reality, the unregistered version has nearly complete functionality with two minor exceptions:
- A “nag” window will appear every time you load a new file.
- You may only run 1 job at a time, so you can't take advantage of the queue and batch capabilities of MP4tools.
The above limitations will disappear if you register the software ($5.99 - the price of a Big Mac dinner around here). Hopefully you will consider the usefulness of this software to be worth the price of a meal at McDonald's :-).
Note, that the output of the registered and unregistered versions of MP4tools will be identical, so you can thoroughly test MP4tools before you decide to support it’s development. Bugs still exist which may or may not get fixed and there are known issues and probably some unknown issues :-). You should probably consider this software as being sold "as is", so test thoroughly to see if you think you’re getting your moneys worth before registering.
When registering, you have the option of registering for just MP4tools, or you can choose to register for the VIDEOtoolbox suite of applications for less than the cost of registering two applications. This will get you a registration code that unlocks all of the suite apps. If you decide to register, download the software using the link below, and then follow these registration instructions.
MP4tools is Intel-only (64-bit) and requires Mac OS X 10.9.x or later. It has been tested on a MacBook Pro and a Mac Pro with no known issues. If you are updating from a pre-3.5.x version, the preferences have been updated and as a result you will need to re-enter your presets, registration code and other preferences. Remember you can find your registration code in the preference panel of the current version. Sorry for the inconvenience.
If MP4tools doesn't quite do what you want it to, you can see if there is a beta version of the software found here. Please help bring the beta software into general release by sending feedback to: firstname.lastname@example.org
