in "too big images" I mean that if I try yo upload to the app an image heavier that 3 Mb I receive an error message says "32 bit image can"t process image this large". also I never manage to apload video files unless I have created them using the "learn/recognize from camera" option in the app.
Send an e-mail with issue description to vaidasz [eta] neurotechnology.com. Send couple of such images as well.
Also provide steps to reproduce the issue.

Yes, you are correct. You could choose resolution that camera returns.

It seems you are missing libraries. Are you sure you have all necessary libraries in your SDK start-up path or in system environment variables.
As you may know, our .Net dlls depends on native dlls. For example, Neurotec.dll depends on NCore.dll. And .Net dlls could not be loaded from system environment variables - they either have to be at same directory as your application start-up path is or in GAC.
My recommendation would be to have all (.Net and native) dlls at your application start-up path.
Also make sure you are using correct dlls - if it is 32bits OS, then dll for 32bits OS; if it is 64bits OS, then dll for 64bits OS.

No, there is not maximum. The more features are extracted in both enrolled model and the one sent for matching, the more score there could be scored. That means, it is not possible to convert the score to similarity percentage.
The scores in range [1-10] could be treated as:
1. Score 700.000 would be 10;
2. Score 500.000 is about 8;
3. Score 150.000 – 200.000 is about 5;
4. 50.000 is bad and it is something like 1-2.

thanks again!
It depends on the codec you choose. Try choosing different one.
