I have a client who self-installed some fairly high end video equipment
at his residence to catch vandals. It worked and he has some really
nice video of the offender and her car (both coming and going) but the
license plate and facial features (the dummy actually opened the
driver's door to throw handfuls of nails on his driveway) are
insufficient for identification purposes.

I have access to the original digital files as I had him pull the hard
drive after making some copies. He had the recorder set to the highest
quality recording level and though I've pulled screen shots (digitally,
not with a camera) frame by frame, I've had no success with Photo Shop
in enhancing the image of the plate or subject.

I thought that the fact his equipment is capable of multiplexing that he
was losing quality in that he was recording, I think, three or four
cameras simultaneously. He presented that to the manufacturer/supplier
and they insist that he wouldn't lose anything there but WOULD lose
quality by recording at 30fps which, of course, is exactly what he did.
The manufacturer says that if he'd recorded at a lower fps rate the
resultant screen captures would have more definition and clarity.

Questions to the group:

1) is this explanation accurate in your experience, e.g. high fps less
detail than lower fps rate? Your response can be shared with the list
as I think it's probably worthwhile for sharing

2) Are you aware of anything or anyone who can take what we're stuck
with and perhaps bring up a clearer image of either the plate or the
subject and, if so, what a ball park figure would be for examining the
files and "playing with them." This latter is best responded to by
private, off-list email to me.

Thanks
