Video from Gopro to 3DR drone

Posted by Prabhu Jyot on November 29, 2016 at 2:07am

Hi,

I am working on a project with 3DR drone with gopro camera. As i studied the video captured by gopro is transfer to solo using the HDMI cable. i want to know what is the video transfer speed from gopro to solo. and according to my information the video is not stored at solo and solo send the video to ground station using the 3DR radio link. the recommended air transfer speed is 64 Kbps. Can we send video at higher speed to ground station with maintain the quality of video.  Can gopro send the video at lower bit rate with  maintain the quality of video over the 3dr radio link

    Yes, the SOLO has a video transmitter.  But I was referring to the 3DR  915 MHz TELEMETRY transmitters that you find all over the net.  Such as -

    I believe Prabhu was referring to this type of unit.

    You cannot send video over a 3DR radio link.  The 3DR radio is for telemetry only (or telemetry/control). It takes 10+ megabits/second bandwidth to send video.  Much, much more than you can ever get through a 57.6K or 64K bit stream.

    If you want to get video out of a GoPro to send to the ground, you cannot use the HDMI output of the GoPro.  Instead, you will need to use the COMPOSITE (analog) video from the USB port of the GoPro using a special cable for that purpose (available from many sources).  You can then choose to send that video signal to the ground using a 1.2GHz or 5.8GHz radio link (or whatever is appropriate for your country).
