what type of files does davinci resolve support

Here's the xor'd stco atom to save everyone the work (offsets start after the 0圆C 108 frames):Ĭode: Select all 00000000 0000006C 000445F8 002B8445 Notable atoms at the start of that chunk are 'ptsb', and 'n3a ' (which is a 0x28A8 atom with 'IMVT' at bytes 4-8 ImageVision Technology is the company behind Z Cam).

The 4th byte is rarely a printable character however.Īnother observation is that each frame has a 0x2904 byte chunk preceeding it that appears some kind of descriptor. Taking a quick look at a few random frames and they all continue the pattern of 'WVx', and x is always a printable ascii character but not necessarily alphanumeric. The first frame is 20b larger than the next 7, and its first 20b are 'PVVVMVVV~VVV', 'Y', 'Z', 'Y', 'B'. Taking a look at the first 8 frames there are a few interesting things. One of the non-standard atoms at the start of the file is 'jpeg', a thumbnail. There are some non-standard atoms, but it's a normal QuickTime file otherwise. If you reverse the process by repeating the xor, it's a valid file and you can then access the frame data directly. In the case of the sample zraw file above, it's 0xDC286E56. They've xor'd the stco (frame offsets) atom/chunk of the 'vide' track with the creation timestamp (in the mvhd atom) of the file.
