I'm looking for some technical expertise..


I have an Arri SR3 Adv, with a video assist - see pic. The output is an analogue phono cable which I have running into a small 7" monitor. The only practical use for the video assist, and all I need it for, is framing. All in all the set-up works pretty well, but it would be handy if I had a way to record the video assist image.


Does anyone know a simple way to record the signal? Either an affordable small recording monitor with phono input, or I was thinking perhaps some hardware and software to turn the analogue signal to digital and record on a laptop.


Has anyone had any experience with this?


Thanks, Greg

What about an Atomos Ninja recorder or something like that? Trouble is you might need to convert the analog BNC signal to a digital SDI using an AJA converter. I do this with a Odyssey7 monitor from an Arri 416.

I wonder if one of those old hard drive based DV recorders or HDV recorders would do the job?


Ok this works. I bought a DVR, which are usually used to record CCTV footage. The phono from the video assist goes to the DVR video-in, then another phono cable from the DVR video-out to the monitor. Playback can be viewed on the monitor, and the DVR records onto an SD card so can be easily viewed on a laptop.


The DVR is small and very light, it's attached to the back of the monitor with adhesive velcro. A small 12v battery powers the monitor and the DVR, I'm looking into ways to attach this battery.


Pics and links below. Apologies for my shoddy phone camera..
