Hi everyone, I’m new to the Jetson Nano community. I work in a research lab and we are trying to build a high speed image acquisition system using the Jetson Nano. We are trying to use the IMX219 Raspberry Pi v2 camera and trying to record videos of about 100fps-120fps in RAW format. I was wondering if: [1] Is it possible to hit 120fps? I read recently that the new version of Jetpack disabled 120fps support for the IMX219 sensor? [2] If it is possible, what would be the best way to do it? I’ve dived into Gstreamer to figure it out and I have come up with this command: gst-launch-1.0 nvarguscamerasrc sensor\_id=0 num-buffers=600 ! ‘video/x-raw(memory:NVMM), width=1280, height=720, framerate=120/1’ ! nvvidconv flip method=0 ! ‘video/x-raw, width=1280, height=720 ! filesink location=test.raw to hopefully be able to capture 600 frames at 120fps. I was wondering if this is the correct way to do it? Also, are there any useful pointers I should take note off to further optimize this pipeline? I have heard people suggesting to save these RAW videos directly into an external drive instead of the root file system. I was wondering if there were some other considerations I should take note of. ---

Not sure, and it may depend on what is the additional CPU load. IIRC, using 120 fps with Xavier NX on recent L4T releases, Argus was using [one full CPU core](https://forums.developer.nvidia.com/t/120-fps-mode-support-removed-for-imx219-sensor/174327/15) (Note that these build instructions may no longer be correct with restriction with local-version to be -tegra-xxx for nvidia drivers modules). > [@msingh44](#): > > [2] If it is possible, what would be the best way to do it? I’ve dived into Gstreamer to figure it out and I have come up with this command: If you can build driver for 120 fps and if it works with Argus, your pipeline is ok (note that nvvidconv flip-method is 0 by default). If it doesn’t fit, you may record raw bayer RG10 from V4L, and use offline converting into another format ---

Hi Honey\_Patoucel, Thank you for your reply. I had a couple of follow up questions I was hoping you could help with: [1] Some of the pipeline commands I have seen online involved specifying a format such as: gst-launch-1.0 nvarguscamerasrc sensor\_id=0 num-buffers=600 ! ‘video/x-raw(memory:NVMM), width=1280, height=720, framerate=120/1 **format = I420** ’ ! nvvidconv flip method=0 ! ‘video/x-raw, width=1280, height=720 ! filesink location=test.raw In my command, I do not specify a format. My intention is to record 10 bit RAW bayer (which is outputted from the Raspberry Pi V2 camera IMX219). To do this, i simply name my file with the .raw extension and specify video/x-raw. Will this get me the 10 bit raw bayer image? [2] Is there a way to analyze the .raw video I obtain from the pipeline command above. Is there some way to print out how many frames there are, the exposure time, the timestamps of each frame? I want to have some verification that there are indeed 600 frames, the frame rate was 120fps and the frames were not being dropped. Thanks in advance! ---

Hi, The output frame data of _nvarguscamerasrc_ is in YUV420. It is the output of hardware ISP engine. If you would like to get raw data, please run _v4l2-ctl_ command like: [Jupyter cannot initialize Raspberry Pi V2 camera - #2 by ShaneCCC](https://forums.developer.nvidia.com/t/jupyter-cannot-initialize-raspberry-pi-v2-camera/73855/2) We have seen stabilitiy issue for 120fps, so the sensor mode is changed to 720p60. ---

Hi DaneLLL, Thank you for your response. I will try this command as mentioned: `v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=RG10 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=1 --stream-to=ov1080.raw` A couple of follow up questions: [1] Is there a way to specify a frame rate in the above command? I know 120fps has stability issues but could I specify a frame rate of e.g. 100fps? If so, how would I do that? [2] Is there going to be a performance decrease in using v4l2-ctl versus nvarguscamerasrc? As I am new to this platform, I am trying to understand these different commands and how they would affect performance speeds? ---

An update to my question [1] above – I am running this command: `v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=RG10 && v4l2-ctl --set-parm=100 --set-ctrl bypass_mode=0 --stream-mmap --stream-count=600 --stream-to=ov1080.raw` and I am only getting about 21fps. If I set the fps to a lower amount like 8, i.e `set_parm=8`, it still goes to 21fps. How should I specify the fps I need? ---
