This thread is in reference to another one, in which my captures were resulting with timing issues. This can be read here. http://www.digitalfaq.com/forum/vide...e-problem.html
I feel this discovery is worthy of its own thread, because there may be people using such equipment with this undetected, unsuspected issue at hand.
I figured out the problem with differencing runtime in my project, and it has to do with the Panasonic DMR-ES15 unknowingly inserting frames throughout on various tapes. Here's the results of my test:
1 tape was played five times each, the same segment running 15 minutes through a JVC-SR10U. The tape in question is a movie with a DVD release; the DVD is ripped and put into the timeline of my non-linear editing software as my main timing reference.
Pass 1: VCR--> PC
Pass 2: VCR--AVT-8710--> PC
Pass 3: VCR--ES15--AVT-8710-> PC
Pass 4: VCR--ES15--> PC
Pass 5: VCR (with TBC turned off)--ES15--AVT-8710-> PC
I put the six video sources into a timeline, on top of each other. Pass 1 and 2's timing matched up precisely and exact to the DVD reference. With the ES15 in the capture chain, there's 1 disgusting inserted frame- and the various capture software I have experimented with are not detecting this. This is examined through a frame by frame analysis of the clips. In Passes 3-5, the inserted frame would be somewhere different in the capture- never in the same spot.
The biggest issue of all of this as stated earlier, is that the software is not detecting these frames, and many of you could be victim to this unknowing inconvenience caused by the DMR-ES15.
I just thought I should post this to let everybody know who is using an ES15 to be wary of this issue. I really want to have a device like this somewhere in my capture chain, since it does magical things with my worn, EP VHS tapes of rare content; but I can't risk this technical issue with a large project of many tapes underway. Does anybody have any suggestions? Would an ES10 not have this issue, or could an AG-1980 possibly fix the issues that the DVD recorders fix? Thank you so much! (picture attached).
