New description:
Summary of the bug:\\
\\
If you apply the "sharpen_npp" filter to a 1080p video, the resolution
will be output at 1088p (a green bar will appear at the bottom of the
video). I tested it with multiple files, and it doesn't seem like the
issue is dependent on a specific video file.\\
It looks similar to the problem below, but in my environment it looks like
a "shapen_npp" problem.
This is because the problem does not occur if "shapen_npp" is not used.

cuda -i test.ts -vcodec h264_nvenc -vf

copy -f mpegts test_deint_denoise_sharpen.ts
