Which option of h264 encoder is better for letsplay recording? (OBS+FFMPEG) Five sets of QP (0-51)!

#h264 #OBS #ffmpeg #qp #CSGO #letsplay #screenrecording https://obsproject.com/ru https://ffmpeg.org/ In this video I compare different types of QP in h264 encoder via FFMPEG. I upscale part of FullHD video to 4k. I change ONLY QP option: 0; 10; 20; 30; 40; 51. And I show bitrate and size of videostream. QP=0 in dinamic (action) videos gives you giant size and bitrate but excellent quality. QP=51 gives you very compact size but poor quality. ffmpeg -h encoder=h264_nvenc -qp - Constant quantization parameter rate control method (from -1 to 51) (default -1) (in FFMPEG) My command for FFMPEG: ffmpeg -hide_banner -loglevel +repeat+level+info ` -ss 00:15:56 ` -i "2022-02-17_dif_qp_original_1080.mov" ` -to 00:00:16 ` -map 0:v:0 -vf scale="w=3840":"h=2160":"in_color_matrix=bt709":"out_color_matrix=bt709":"in_range=limited:out_range=limited":"sws_flags=neighbor+accurate_rnd+full_chroma_int+full_chroma_inp":"srcw=1920":"srch=1080":"dstw=3840":"dsth=2160":"src_format=yuv444p":"dst_format=nv12":"sws_dither=x_dither" ` -noautoscale -c:v:0 h264_nvenc -gpu 0 -vsync 1 -framerate copy -video_size copy -rc constqp -init_qpP 0 -init_qpB 0 -init_qpI 0 -rc-lookahead 0 -maxrate:v 512M -bufsize:v 512M -pix_fmt nv12 -profile:v high -preset p7 -tune hq -level 6.2 -coder vlc -weighted_pred 0 ` -sws_flags neighbor+accurate_rnd+full_chroma_int+full_chroma_inp ` -map '0:a:0' -c:a:0 copy ` -color_primaries bt709 -color_trc bt709 -colorspace bt709 -color_range "tv" ` -metadata title="FFmpeg_Screen_Recording" -metadata comment="$(get-date -f yyyy-MM-dd_HH-mm-ss)_any_comment" ` -f mov -write_prft wallclock ` "FFmpeg_filter_$(get-date -f yyyy-MM-dd_HH-mm-ss).mov"
