24p on interlaced monitor !

[amourgues]

I have a PANASONIC BT-LH1700WP monitor and I don´t know what´s the best setting to monitor when shooting 24p. Does anybody have this monitor ?It displays at 1080/60i. Apparently, I can not swith to a progressive display, unless you use a GPI-D-SUB, 9 pins or RS-232C: D-SUB, 9 pins remote unit for external control. I don´t know what the hell is that, and the manual is useless. Anyhow, I´m a bit confused here. If you shoot 24p, should you monitor the signal in progressive mode too ?....What does it do to the input signal if the diaplay mode is interlaced ?...what difference does it do the frequency or refresh rate ?....
how sould you set your monitor in relation to the camera settings, concerning frame rate, refresh rate, shutter speed, monitor frequency ?

What´s the relation between recording frame rate, display frame rate and refresh rate ?...how do the conversions between them work ?

What settigns should you set in your MAC en every case ?...Do you hace to change your settings everytime according to your shooting parameters, or there is a standard set of values for setting your monitor and MAC to work properly ?

I´ve read a lot of this stuff but it´s a bit overwhelming !

I've used that monitor with the HDX-900 shooting 24 on 60, and it worked fine. I suppose the monitor would probably just add 2:3 pulldown if the camera can't. Is it possible to output 24 on 60 (ie. with 2:3 pulldown already put in)?

Also, I assume you mean 23.976p, not 24p. 24p can't be monitored on standard NTSC playback devices, from what I know.

[Jeff Kilgroe]

Umm.... The BT-LH1700WP is an LCD display and is progressive, not interlaced.

How are you connecting to the monitor? With what hardware?

[amourgues]

I´m monitoring the shooting connecting the camera directly to the monitor thought the SD-HD camera output.
The camera is shooting 24p, but the monitor is displaying 1080/60 on the screen (what does this mean ?)....The SYSTEM-MONITOR-SD/HD is set to 60Hz
Is this ok ?....what am doing wrong ?..what´s the effects of these camera/monitor parameters...Now I´m more confused !
thanks

[Jeff Kilgroe]

The camera only outputs NTSC (59.97Hz "60Hz") or PAL (50Hz) via HD-SDI. So even if you are shooting in 24fps, output is still over a 50/60Hz signal.

Camera can only output 1080p for playback, not while recording at this time. During recording, output is 720p.

The Panasonic monitor does not accept a 1080p input signal. You need to set your camera output modes to 720p for use with the Panasonic monitor. What could be happening is that the monitor is being fed a 1080p signal, and it can't understand it. It's trying to display it as 1080i, but obviously can't do this.

[Mitch Gross]

Do you have an image on the screen? If so then do nothing, it is woring fine. The default setting for the video standard feeding to the camera via HD-SDI is "Auto," which means that the monitor will automatically detect what type of signal is being fed to it and adjust accordingly.

If it works, then it is working at its best.

[Adam Glick]

Does your gear support 24PsF mode ?

This will essentially allow a non24p-compliant monitor (or other video I/O device) to display a 24P signal using a "48i" interlaced mode -

This PsF mode is supported by many 60i compliant devices

[Jeff Kilgroe]

...But the RED One does not support PsF or output any sort of interlaced signal. He is attempting to connect the monitor directly to his RED One. All he can do is set the camera output to 720p PAL/NTSC and connect the 720p out on the camera to the HD-SDI input on the Panasonic. If it works, then it works. If not, he has a problem.

[Stuart English]

According to the Panasonic Broadcast web site that monitor supports 720p/50, 720p/59.94, 1080p/23.98, 1080p/24.00, 1080p/25 and 1080p/29.97 in progressive (i.e not PsF) mode.

These are the same frame rates and resolutions available from the RED-ONE.


p.s 720p is NOT a PAL or an NTSC signal (just to keep our nomenclature correct)

[Gabriele Turchi]

Stuart but even the Blackmagic HDLink Pro accept 720p 59..94...But it does not work with the RED SDI signal...

Having the RED at 24fps the HDLINK Pro works quite well (1 drop of signal every minute) , having the RED at 23.98 , signal unstable and unusable..

They told me that the signal out from RED is a bit out SMPTE ... But i know that the SDI out From RED works perfectly with Aja SDI in...

"What does it do to the input signal if the diaplay mode is interlaced ?...what difference does it do the frequency or refresh rate ?"

If you are concerned about the "input signal" being recorded by the sensor to the flash drive, there is no problem. It is unaffected by the output to a monitor. The signal being sent out to a monitor ("output signal") should not have any effect on what is recorded.

[Stuart English]

Stuart but even the Blackmagic HDLink Pro accept 720p 59..94...But it does not work with the RED SDI signal...

Different subject, different issue (please see that thread for more details)

This response is in reply the original question about the Panasonic monitor.

[Gabriele Turchi]

I am sorry about that...You are right about the off topic ,

But actually i was trying to say that maybe that monitor is incompatible too....

And to be Honest :we never had any news about that issue (that is still an issue (tested with Build 18 and the very last firmware on the HDLINK Pro))

Of course, it's $1500 bucks, but he could try this converter- and go analog component to the monitor...

But in fact it isn't, we have tested with one of these Panasonic monitors at RED :red_bandana:

[Rich Schaefer]

I have 3 of the BT-LH1700s they work great with the Red. They are the main monitors I use with my red. They work with both 23.98 and 29.97! There is now a new version the BT-LH1760. PM me and I will fire one up and share my settings.

I've sent my 1700 480i, 480 p, 720p and 1080p signals and it does fine. You don't have to send it a 720 p signal. It rescales it automatically.

[Jeff Kilgroe]

Yeah, looks like 1080p on the 1700WP will work just fine. The older Panny 17" LCD I had didn't take 1080p. Actually got rid of it for that reason. It was their first gen 17" LCD field monitor, I thought it was the BT-LH1700, don't recall if there was any letter designation on the end of that model number.

Ok, The RED´s FAQ explains: "The EVF video output is 1280 x 720 Progressive, the LCD video output is 1024 x 600. 720P can be tapped from the HDMI and HD-SDI ports, while HD-SDI Dual Port and HDMI will provide 1080P output in playback only
As matter of fact, when shooting 4k 2:1 24p, the status displays on the screen shows 1080/24p in playback mode, but it actually shows 1080/50p when recording. what is it actually doing ?...

Are you talking about the graphical info displayed on the monitor by the RED One?

If so, how did you select to record at 50fps? What is your frame rate in the project settings?

If your project is set to 24fps and you change record speed to 50fps in the Varispeed menu, it will record at 50fps and display at 24fps in slow-motion. If you want to record and play back at 50fps, you must set your project frame rate to 50fps.

[amourgues]

Jeff. I mean the status display on the external panasonic monitor. I'm recording 24p, but the display on the externalmonitor 720/50p when recording, but in playback it shows the right thing: 1080/24p....
