Here's your problem
You're converting an already low-ish bit rate HEVC 4K video to H264. 7Mbps H264 is not enough bits for good 4K. Heck, 7Mbps HEVC 4K (the original bit rate and codec) isn't great either.
For reference, my 1080P HEVC files are ~10.5Mbps for the video stream.
Code:
Stream #0:0 -> #0:0 (hevc (native) -> h264 (h264_nvenc))
Stream #0:0: Video: h264 (Main), cuda(tv, bt709, progressive), 3840x2160 [SAR 1:1 DAR 16:9], q=2-31, 7076 kb/s, 23.98 fps, 90k tbn (default)You're converting an already low-ish bit rate HEVC 4K video to H264. 7Mbps H264 is not enough bits for good 4K.
