This has been asked a couple of times. How do I record the slow motion S&Q output of my PXW-FS5 to an external recorder if I don’t have the raw option or don’t want to use raw.
Well it is possible and it’s quite easy to do. You can do it with either an SDI or HDMI recorder, both will work. The example here is for the new Atomos Ninja V recorder, but the basic idea is the same for most recorders.
Just to be absolutely clear this isn’t a magic trick to give you raw with a conventional non raw recorder. But it will allow you to take advantage of the higher quality codec (normally ProRes) in the external recorder.
Oh and by the way – The Ninja V is a great external monitor and recorder if you don’t want raw or you need something smaller than the Inferno.
So here’s how you do it:
In the camera menu and “Rec Set” – set the file format to XAVC HD and the Rec Format to 1080/50p or 1080/60p it MUST be 50p or 60p for this to work correctly.
In “Video Out” select the HDMI (for the Ninja, if you recorder has SDI then this works with SDI too).
Set the SDI/HDMI to 1080p/480i or 1080p/560i it MUST be p not i
Set HDMI TC Output to ON
Set SDI/HDMI Rec Control to ON
Connect the Ninja (or other recorder) via HDMI and on the Ninja under the input settings set the record trigger to HDMI – ON. If you are using a recorder with SDI you should have similar options for the SDI input.
So now what will happen is when you use the S&Q mode at 100fps or higher the camera will act as normally, you will still need a SD card in the camera. But when the camera copies the slow motion footage from the internal buffer to the SD card the external recorder will automatically go into record at the same time and record the output stream of the buffer. Once the buffer stream stops, the recorder will stop.
The resulting file will be 50p/60p. So if you want to use it in a 24/25/30p project and get the full slow-mo benefit you will need to tell the edit software to treat the file as a 24/25/30p file to match the other clips in your project. Typically this is done by right clicking on the clip and using the “interpret footage” function to set the frame rate to match the frame rate of your project or other footage.
And that’s it. It’s pretty simple to do and you can improve the quality of your files over the internal recordings, although I have to say you’ll be hard pushed to see any difference in most cases as the XAVC is already pretty good.
