Sounds about right to me.
SpoRv, What you could do is XOR one clip with another, could even use a single frame to XOR the whole clip, and use same single frame clip to both 'Encode' and 'Decode'.
I think MaskTools should have XOR capability. [Sometimes called EOR]
As a daft example, could use eg
Code:
RandomSource(Length=Len,Width=W,Height=H,Seed=SECRET_KEY).ConvertToYV12(Matrix=PC601) # to match target clip. EDIT: ADDED MATRIX arg to make better (full range) key clip
as your 'key' encode/decode clip.
Apply XOR, using the key clip, and decode using equivalent key clip at the other end.
All you need pass is the encoded clip, and the SECRET_KEY to create the 'key' clip.
(You could also just use any clip that you both have as a key clip, maybe with fixed seed AddGrain)
EDIT:
If A XOR B = C : Then C XOR B = A [EDIT: Also, C XOR A = B]
EDIT: I believe that above is how RAID 5 works, the third drive (DRIVE_C) holds result of DRIVE A XOR DRIVE_B,
if either drive A or Drive B fails, it can be recovered [EDIT: to a new drive] by XORing the remaining drive with DRIVE_C.
