Is it possible to record to tape at the same time? It would be interesting to see the same shot both ways, especially a scene with intense color (like the red shirt of your first post or the blue car I've attached) to compare 4:2:2 with 4:2:0 subsampling.

It is an exact remark. I will make an effort do it in the near time.
(you did a very large magnification:)

Yeah, it's a 200% enlargement. Just so that it is easy to point out the visible artifacts of 4:2:2 sub-sampling. (It should be much better than HDV's 4:2:0 sampling when recorded to tape.)

It very strange, but they are not written down simultaneously on tape and in a file, but I will try...

Svyatoslav, thanks for your contribution, I'm following this thread with plenty of interest.

Best regards

Svyatoslav,
Are you sure? I don't have a way to record HDMI, but I have monitored HDMI and recorded at the same time. The camera shouldn't care.

Certainly. I had because of synchronously under a management from a computer.
