Low quality video issue on Jetson nano


I found some issues when I record 30Hz 4K videos with Jetson nano.
The video seems to have lower pixel resolutions unlike still captured image with 4K.
This degradation occurs when capturing moving objects. When the scene do not move, it’s quality gets better.
I attached videos and the still capture image.![nvcamtest_11711_s00_00001|640x480]
The pipeline I used is below.

gst-launch-1.0 -e nvarguscamerasrc num-buffers=300 sensor-id=$SENSOR_ID ! “video/x-raw(memory:NVMM), width=4032, height=3040, framerate=30/1” ! nvv4l2h264enc ! h264parse ! mp4mux ! filesink location=rpi_v3_imx477_cam$SENSOR_ID_$FILENAME.mp4



Be default bitrate setting is 4Mbps. This can be too low for 4K resolution. Suggest you try higher bitrate.

Setting virtual buffers size may also help. Please refer to the setting in
