Print To Tape: VF versus Studio7

Well, following Soundguy63 also getting the problem of Drop Out using PTT in VF, and having to complete a project on time, sent the project using PTT in Studio 7. I too again fell back on my "back-stop" of doing the same through S7.

Here are my results:
Using System Monitor I have been able to establish that when using Studio7, I have achieved a reduction in processor usage of 50%.

In VF: 60% - 70% processor usage.

In Studio7: 20% - 35% processor usage.

NB: This is what I got when I posted the "PTT Cracked It!" thread. - Sorry folks it was in Studio7 that I achieved this reduction - NOT VF.

Soooo… what does this tell me:

1. My system of External Maxtor drive and Firewire set-up works. It also confirms to me that the rendered pre-PPT clip was capable of being used for PTTing - no breaks/leaks in timecode.
2. Processor Usage [PU] is critical to PTT - Too much PU [60%-70%] = Drop-out; Optimum PU [20%-35%] = No Drop-Out.

Added to which, within S7 you get position control of the transport of the clip, right down to a single frame point. I don't see this as available in VF. This means, should I ever get "Drop-Out" in S7 in the future, I can stop the process, re-cue both PTT process and shuttle tape on VCR to the "Drop-Out" position and recommence. This is both neat and controllable.

I was hoping to get a solution for VF's PTT. Hey "You can't always get what you want!". However this might be the identification of a bug in the VF PTT procedure, which our friends at SF might wish to consider correcting. Stranger things have happened!

Grazie
