The JB-1 generates, reads, and jam syncs timecode, offering six preset and two user-selectable output levels. Its Temperature Compensated Crystal Oscillator (TCXO) eliminates the need to jam more than once per day.

Will this work with Convergent Design's Apollo to insert time code when ISO recording?
Asked by: Steve
according to the manufacturers manual connect the JB-1 to LTC I/O port, as long as you are using that time-code port as the selected time-code source, the time-code that's generated by JB-1 will be read and show up on the Apollo.

What happens with the timecode when I am recording at 60fps?
Asked by: Brian
From the manufacturer; 60fps is the Video Frame Rate. The TC frame rate will be half of that. So, 60 fps Video = 30 fps TC. Please note, that many times the video frame rate is referred to as '60' when it is actually '59.94'. In this case, the timecode rate is 29.97fps. I have a strong hunch that this is the case here. 30\60 is very rarely used theses days.

Can I use this device with the Blackmagic Pocket Cinema Camera 4k? What adaptor would I need to get this to work with a bmpcc 4k?
Asked by: Michael S
Yes it works with the Pocket Cinema Camera 4K. The camera is able to accept SMPTE compliant LTC timecode via the 3.5mm microphone input on the camera. Please check the manual of the camera for more details. If set up properly you will be able to embed the timecode in the video file (no need for pluraleyes or special software) and capture scratch audio if needed. You will need a BNC to 3.5mm cable to make it work. For example you may want to consider the Remote Audio 3.5mm Right Angle to BNC Right Angle Cable - 18" (BH #RECATC18BNC • MFR #CATC1/8BNC)
