HDCAM mastering – Sony M2000 problem

[Mark Raudonis]

You realize that the SONY DVW-M2000 is a standard def deck NOT capable of recording HD video?

yes, but the HDW-M2000 is an HDCAM record deck.

make sure the deck Reference is set for INPUT when doing an insert edit.

Eric,

Thanks I’ll double check for that – and indeed it is a HDW – M2000 (I think I may have noticed if otherwise!!!)…. It looks like more than a sync issue though. I’ve left for the evening now – but I thought that I might check the settings on the deck – I’m 99% sure that 1080 25pfs was what it was showing…..

If your sequence is 25psf then that is the correct settings. However, try the 50i setting as well. I have had the same problem with that deck and it is both the reference input setting and the 50i 25psf setting.

In my case I was 50i and the deck was set incorrectly to psf but it gave me the same garbled greenish blocking

Just to follow up with what was the issue……………

Thank you Michael – I’d suspected it might be the 25 PfS / 50i issue as I said in a previous post – but your post pretty much confirmed that for me.

What I found is that although my timeline was ‘progressive’ – Blackmagic doesn’t support 25Pfs – only 50i – hence the garbled picture on edit to tape. So the deck had to be set to 50i.

A technical query – A ‘progressive’ (no field dominance) timeline – laid off onto tape at 50i – is that still technically progressive – as both fields are the same???????

Many thanks for your input – everyone who has posted.

Mark,

The sequence bed is 50i and the material is 25psf in your case. That is still a progressive image. If your material was not psf then you would need to set field dominance to upper. Even if you set it to upper, it makes no difference to the image if it was shot 25 psf.

As all my work is broadcast with some digital projection in small cinemas, I always use an interlaced sequence and that way I can have both 50i and 25psf in the same timeline. The roll credits look smoother to me in interlaced.
