Hi, when I save the images from my bluerov2, a gray screen appears every 5 to 10 seconds (it lasts 1 second or 2). On the other hand, when I watch the recorded video, there is no trace of this lack of data. It bothers me to fly diving of course. Someone would have any idea ? Sorry for my English, I’m French. ---

Hi My guess is this: > [@Video freezing and grey frames in QGC 4.0.5 when recording](https://discuss.bluerobotics.com/t/video-freezing-and-grey-frames-in-qgc-4-0-5-when-recording/7423/23): > > Hi! Uppgraded to QGC 4.1.2 that seems to solve the problem. In QGC application settings there now is a listbox setting for chosing the video decoding in QGC. Using the standard “default” seems to be a mix of using the nVidia card and software decoder, in plain english the video freezing happens sometimes, even if processor load never goes over 45%. I think there is a mix of software/GPU usage happening in this state. Using “Force nVidia” gives good video with no freezing, but video mp4 reco… ---

it is very possible, but the last downloadable version of QGC on the Bluerobotic site is 4.0.5 … where can I find version 4.1.2 for BlueRov2? ---

I tried with version 4.1.2 and above, the problem is solved for the gray screen in video stream but I no longer have the joystick test on the general tab even after calibration. ---

> [@Bruno1](#): > > I tried with version 4.1.2 and above, the problem is solved for the gray screen in video stream 4.1.x should solve the video issues, as @Boko mentioned. If you’re using 4.1 we strongly recommend \>= 4.1.4, as that release contains several ArduSub related improvements that weren’t in earlier versions of QGC 4.1. > [@Bruno1](#): > > I no longer have the joystick test on the general tab even after calibration. This seems odd, but I’ll respond to it in [your other topic](https://discuss.bluerobotics.com/t/problem-with-qgc-video-stream-and-gamepad/10687) that you made for that issue. ---

Hi everyone, in the last deployment of the BlueRov2 I did forget to start recording. During this dive I had no gray screen. When I start the recording, I have gray screen. After the software update, the count of appearance decreased. But when they appear occur, it’s really annoying. The appearance is randomized. I cannot observe any patterns. The software is installed on a Windows 10 laptop. There is installed only essential software and QGC only, no games, no mail, no Office etc. During the deployment of the ROV, Bluetooth and WLAN are switched off. Does anyone knows a solution? Best regards Frithjof ---

Hi @dr_stony, welcome to the forum 🙂 Which QGroundControl version are you using? If you’re not already using 4.1, please try the latest recommended version, [4.1.6](https://github.com/mavlink/qgroundcontrol/releases/v4.1.6) ---

Apologies for the delay in responding. > [@dr\_stony](#): > > I have 4.2.0 4.2.0 isn’t a version we support for use with ArduSub - our [latest recommended version](https://bluerobotics.com/learn/technical-reference#software-and-firmware) is 4.1.6. Previous grey screen issues have been handled by changing the video decoding options, as [discussed here](https://discuss.bluerobotics.com/t/video-freezing-and-grey-frames-in-qgc-4-0-5-when-recording/7423/23). These [troubleshooting steps](https://www.ardusub.com/reference/troubleshooting.html#poor-video-streaming-performance) may also be helpful 🙂
