I received both raw .ari files and pro res proxy dailies from an Alexa camera shot at 2K (2880x1620) at various frame rates - 23.98, 48, and 60 fps.
The problem is that the timecode of the .ari files does not correspond to the dailies (the proxy dailies were made from the Pro Res HQ spit out by the Alexa).
Because the timecode does match up, it becomes a pain when getting from the offline to transfer house and again to conform. I have a workaround between the two houses, but it is time consuming, so if anyone knows anything - how, why, what, and when about this problem and its solution, I'd appreciate it.
When contacting the DIT on set, he told me "he contacted the manufacturer of the codex system who said there is nothing they can do about this. However, to help, the dailies timecode of the 2K footage shot at 48fps is exactly half of the TC of the raw footage. The 2K at 60fps doesn't have as easy of an equation."
The Codex doesn't kick in until it receives a signal while the Prores starts recording immediately. As far as I know, there's nothing you can do about it because the Prores clips will always be longer than the raw.
