Hello. I just want to introduce you a new auto-sync tool of my personal development - Syncaila.
I'm a videographer and a programmer in one person. And shooting on DSLR, I always needed a tool that could sync a sequence of a full shooting day (without splitting it into small parts) automatically and with a maximum chronological accuracy. I've developed a software that I needed myself.
Maybe some of you need such a tool too. You can test it and use it.

Looking forward to answering your questions.
