However, this matter isn't just about vendor's using better business etiquette with customers. Charging $20 (currently $26.00 AUD) for an upgrade so soon after the initial product release seems opportunistic. Vendor's such as Christopher Vranos understand the importance of customer loyalty. It's regretful that his encouragement of customers and lack of mean spirit isn't emulated by more vendors on this site.
As a tool ReTrack is something that has no comparison, a must have if you work with tracking, masks etc.
Can this tool re-track 3D camera tracker from a wacky footage? Happens that I work a lot with that tool in GTA Gameplay and it gets really bad at the point where It doesn't even track. But there are some times where it tracks some frames, even when it's not shaky or anything, I don't know why, but it does that. So I was wondering If I could re-track it or something like that.
