The MD5 code and what it means

In case there is a problem with your file upload or USB stick we have a backup called the MD5 checksum code. We can use this to validate entries were completed before the 7 pm Deadline using a 'digital signature'. This needs to be sent to us in the online wrapup form (before 7 pm on Sunday) and can prove that the film existed before the close of the competition. It is optional but it is an insurance policy in case things go wrong.

The MD5 'signature' is a simply a line of text similar to a serial number. 

It is created by tiny free software apps (listed below), and is as simple as selecting your completed filename, and waiting less than a minute for the unique text code to appear.

Be sure to put this MD5 code in your completed online Wrapup form before 7 pm. 

Try it now by sending it to yourself, and check it against the file you created it with.

Remember this code is only good for the exact file you created it from. If you output your film again (even without re-editing) it will have a different signature and won't match. If there is a problem we will ask you to send the file that matches the code on your wrap-up form so if you create several versions of your film during editing - make sure you don't mix them up.
