Yep, the safest option is XDCAM 4:2:2 wrapped in a OP1a MXF.
Yes it is.
Are you referring to streaming services or traditional broadcasters?
H.264 is great for streaming but not great for editing.
From October we will also accept AVCintra class 100 as part of the new DPP delivery specs.
Many European broadcasters have adopted it as the new standard.
Not sure what is happening on the other side of the “pond”.
I certainly couldn’t afford them but since the station has them…
Send some, when I have a gap will run them trough.
Another option may be AVS scripts to detect interlacing, I don’t have the time to learn them and don’t know how reliant they are on ffmpeg, if at all.
Yet another way to interlace footage is to get a real time scalar/interlacer.
We have just a unit which we use to put skype calls on air.
The HDMI output from a mac we patch through the scalar (with ref in, in your case you can have it free-running ) and out comes interlaced video 1920 X 1080 (with embedded audio) on SDI.
This SDI output you could then record on a ATOMOS recorder or similar.
