We are using Wafian HR-F1(http://www.wafian.com/HR-F1.htm) for record and playback of Digital Cinema Camera footage. Using 1080p output of Red One camera, unable to see the picture clearly. When I've the settings switched in my Wafian to 720p50, It works. The same 1080p24 works very well with Phantom HD Digital Cinema Camera. We are facing the problem only with Red One 1080p output.

Thoughts and Suggestions welcome.

The RED ONE only spits out 1080p in playback - and even then it is dual-link HDSDI on the main SDI outputs and single-link 422 on the 'Preview' HDSDI.

One thing to check is that you don't have OPEN GATE turned on - that might switch the output to 720p50/720p60.
 
1080p Output

1080p Output

Is only available on playback. I assume that it will be 1080p / 25 if your project TIME BASE was also 25.00.

And use the PVW output if you want 1920 x 1080 in 10-bit 4:2:2 format.

Make sure your PLAYBACK setting is 1080p also, else you will get 720p on record and also on playback.

mayby the same problem as with the wave came, that it not works with real progresive frames (one full frame)in 1080 and only works with psf. in 1080 (two times the same field in one frame used by Sony for instant)
 
True 1080p?

Tried both 1080p and 1080psf settings on Wafian.

Would like to clarify from Red whether the camera preview output is true 1080p or not?
 
The camera preview is 720 but the playback can be set to 23.9/1080P (not pSF) and recorded by some (non-Sony) decks. The 4:2:2 single link is on the preview output connector.
We have recorded the playback directly on a HD-D5 deck.

As Keith says,

The PVW output is 720p, but it can be forced to 1080p when the camera is in PLAYBACK, provided you have set the camera's PLAYBACK MODE to 1080p.
 
what is the difference between preview out and playback out. Will it change?
Is red outputs 1080p on preview?
 
what is the pulldown candence red uses for 720p playback.
 
Preview versus playback.
Preview means you see what the camera is seeing at the moment.
Playback means you see what you have recorded when you play back your files from the camera.

the preview 720p is the same connection as the 1080p in playback when you are at 1080p 4:2:2

When you use the other two output connection you wil have with 2 sdi cables a 1080p 4:4:4.

I use them with a blackmagic box together with my 23 inch apple cinema screen. Most othe time with the blackmagic box from the preview output in 1080p 4:2:2. When not in playback you see a smaller 1280x720 picture and at playback it change into a 1920x1080 picture.

PVW pulldown

PVW pulldown

what is the pulldown candence red uses for 720p playback.

Depends on whether you have asked for 720p/50.00 or 720/59.94.

And then when you have recorded 2K / 3K / 4K RAW at 25 fps or 23.98.

If 50.00 and 25 the pull down is 2:1

If 59.94 and 23.98 the pull down is 2:3

Those are the most common ones, pulldowns but more generally speaking the camera applies whatever pulldown is necessary to convert the capture / playback frame rate to the selected PVW output frame rate.
 
our camera restarts on playback and the restart issue inconsistent.
We want to playback recorded media onset.

There is no such thing as 720p/24 video. That format is a data format only. The only valid video formats for 720p are 50, 60, and 59.94.
 
720p / 24

720p / 24

If your recorder can detect a 2:3 pulldown, then yes you can generate a 720p / 23.98 fps file from the 720p/59.94 input. But you need to talk to them about that.

Note: this has been done before with at least one other camera that output 720p/59.94.
 
will red output 1080p from preview hd-sdi?
