You can see why major software companies are adopting a subscription based regime rather than selling outright. It gets you a steady income stream rather than relying new sales or releasing chargeable upgrades. This is particularly important in a mature or saturated market. I’ve heard it said that VRD is a tad expensive but I think the reverse: compared to the high-end (and maybe bloated) packages it is good value. VRD has the facilities and agility that I want.
I have come to value VRD highly because of its support for resolving glitches and adapting to minor changes in source files. Broadcasters are tweaking things constantly. However, major changes are, as ever, coming such as ac4 and H266, which would reduce the usefulness of VRD in the longer term unless a way is found to continue development and make some of these features available. (Fortunately the UK market us slow to adopt such changes so I should have longer). You could liken VRD to a shark, it has to keep moving forward or it dies.
And there is the question of the balance between the professional and home user versions: if you keep both you need to maintain adequate differentiation.
Whether the will be prospective buyers of the existing product is the question. Fingers crossed.
VRD is testimony to Dan the owner and Dan the developer.
