I’m starting recovery and “beautification” of a nice series of old takes (Panasonic GH2, I think). Resolve Studio 18.6.6 in current use (FCPX also an option).
Material was actually stored as unencrypted “Blue Ray disk” on the SD Card. Looks similar to real ones. Access to media is not a problem. Format of the single files are no secret either, as can be seen here:
Before committing to a specific approach, maybe someone here has a practical tip or two. Simple advice, along the lines of “don’t initially waste time on…” etc. Never hurts to listen.
Content is South Korean historical “royal guard” performance in central Seoul. Lot’s of movements, also near shots, even across the lens (opposite direction in some cases) and probably rolling shutter too in 25fps interlaced and heavily compressed 1920x1080 AVC media (MTS format). As seen in MediaInfo above.
I don’t expect the “repair, beautification, restoration” etc operation to be easy, to tell the truth. There are some really messy scene details in some takes, like several level of ’spear handlers' moving fast paced across the lens in opposite directions is not the easiest to correct in post.
Sound is surprisingly good stereo. That can be handled. Microphone far better then, than was currently expected.
Media has personal value, and no time limit is involved in restoration, so any of my machines can be dedicated for days on end (the Apple Silicon M1 mini for instance, even if ProRES is not supported on chip). Naturally AFTER verifying the approach on a few “snippets”.
Output format still to be determined. I’m not planning on saving any storage space in converted material; aiming at 1440(p) or even 2180(p), if the latter shows any visible promise in final render. Time will tell.
In some months I plan to revisit South Korea during Chuseok - one day later in the year, than in 2011 - and do a few repeat takes of personal interest, if possible. Bookings completed.
Regards
