I was testing libx265 encoder and I was that when psy-rd is enabled for 444 input, the quality is halved. Here are my encoding settings: # Video capture encoding settings cap_soundcommand "ffmpeg -f s16le -ar %s -ac 2 -i - -c:a aac -profile:a 1 -q:a 2.0 -y temp_a.nut" cap_videocommand "ffmpeg -f rawvideo -pix_fmt rgb24 -r %r -s %wx%h -i - -c:v libx265 -crf 25 -preset medium -y temp_v.nut" cap_muxcommand "ffmpeg -i temp_v.nut -i temp_a.nut -c copy -y %f" cap_tempfile1 "temp_a.nut" cap_tempfile2 "temp_v.nut" cap_remove_tempfiles 1 cap_wipescreen 0 cap_fps 60 ffmpeg version 2023-12-18-git-be8a4f80b9-full_build-www.gyan.dev Copyright (c) 2000-2023 the FFmpeg developers built with gcc 12.2.0 (Rev10, Built by MSYS2 project) configuration: --enable-gpl --enable-version3 --enable-static --pkg-config=pkgconf --disable-w32threads --disable-autodetect --enable-fontconfig --enable-iconv --enable-gnutls --enable-libxml2 --enable-gmp --enable-bzlib --enable-lzma --enable-libsnappy --enable-zlib --enable-librist --enable-libsrt --enable-libssh --enable-libzmq --enable-avisynth --enable-libbluray --enable-libcaca --enable-sdl2 --enable-libaribb24 --enable-libaribcaption --enable-libdav1d --enable-libdavs2 --enable-libuavs3d --enable-libzvbi --enable-librav1e --enable-libsvtav1 --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxavs2 --enable-libxvid --enable-libaom --enable-libjxl --enable-libopenjpeg --enable-libvpx --enable-mediafoundation --enable-libass --enable-frei0r --enable-libfreetype --enable-libfribidi --enable-libharfbuzz --enable-liblensfun --enable-libvidstab --enable-libvmaf --enable-libzimg --enable-amf --enable-cuda-llvm --enable-cuvid --enable-ffnvcodec --enable-nvdec --enable-nvenc --enable-dxva2 --enable-d3d11va --enable-libvpl --enable-libshaderc --enable-vulkan --enable-libplacebo --enable-opencl --enable-libcdio --enable-libgme --enable-libmodplug --enable-libopenmpt --enable-libopencore-amrwb --enable-libmp3lame --enable-libshine --enable-libtheora --enable-libtwolame --enable-libvo-amrwbenc --enable-libcodec2 --enable-libilbc --enable-libgsm --enable-libopencore-amrnb --enable-libopus --enable-libspeex --enable-libvorbis --enable-ladspa --enable-libbs2b --enable-libflite --enable-libmysofa --enable-librubberband --enable-libsoxr --enable-chromaprint libavutil 58. 34.100 / 58. 34.100 libavcodec 60. 35.100 / 60. 35.100 libavformat 60. 18.100 / 60. 18.100 libavdevice 60. 4.100 / 60. 4.100 libavfilter 9. 14.100 / 9. 14.100 libswscale 7. 6.100 / 7. 6.100 libswresample 4. 13.100 / 4. 13.100 libpostproc 57. 4.100 / 57. 4.100 Input #0, rawvideo, from 'fd:': Duration: N/A, start: 0.000000, bitrate: 5308416 kb/s Stream #0:0: Video: rawvideo (RGB[24] / 0x18424752), rgb24, 2560x1440, 5308416 kb/s, 60 tbr, 60 tbn Stream mapping: Stream #0:0 -> #0:0 (rawvideo (native) -> hevc (libx265)) x265 [info]: HEVC encoder version 3.5+113-8787af124 x265 [info]: build info [Windows][GCC 13.2.0][64 bit] 8bit+10bit+12bit x265 [info]: using cpu capabilities: MMX2 SSE2Fast LZCNT SSSE3 SSE4.2 AVX FMA3 BMI2 AVX2 x265 [warning]: halving the quality when psy-rd is enabled for 444 input.

Last time, I encoded the Video Capture in Lossless audio and video codecs (ffv1 and flac) and stored them in .mkv container. While encoding with the previous lossless video in libx265, and in aac audio, I had got VMAF score of around 72 for 1080p CRF=28 -preset medium. But, when I encoded the same video in CRF 23 and libx264, preset medium, aac audio, I got VMAF score of around 96! The libx265 ffmpeg encoding settings say that CRF of 28 for libx265 should be same of CRF=23 of libx264, but I am getting very low VMAF scores, at CRF=28, ffmpeg. I think, psy-rd is the main reason for decrease in video quality. How to fix this issue ? Can anyone please help me ?

Blender: a FFmpeg frontend?
by Jamenson Espindula 31 Dec '23

31 Dec '23

Hi all. Congratulations for the terrific software. I am so sorry if the question is a non-sense. I am totally new to Blender, but I noticed that software uses some libraries from the FFmpeg project (libavcodec, libavdevice, libavformat, etc.). Also, Wikipedia says Blender uses FFmpeg. Blender itself says ("Output Properties") the "File Format" in the Video Sequence Editing (VSE) is "FFmpeg Video". So, #1: is Blender a kind of frontend of FFmpeg? #2: Can all Blender's operations on video be achieved by FFmpeg? Thank you all in advance. Happy 2024 to you all!

Intel QSV and xstack_qsv: Error while filtering: Internal bug, should not have happened
by Shane Warren 29 Dec '23

I'm testing out an Intel Flex 140 card and I am attempting to transcode 4 inputs to 1 output using the xstack_qsv filter.

Question about random() expression

Hi, I'm using this command line to print four consecutive random numbers: ffmpeg -loglevel repeat -f lavfi -i color=gray:size=1x1,format=gray -vf geq=lum='st(0,0.123);print(random(0));print(random(0));print(random(0));print(random(0));0' -frames 1 -y out.png The output is always the same four numbers: 0.000000 0.000091 0.285346 0.929202 Why is the first number always zero, even if I write different seed values (here: 0.123) into variable 0?

True range of native AAC encoder.
by Aditya Dandavate 28 Dec '23

28 Dec '23

I was encoding with VBR native FFMPEG's AAC encoder i.e using `-q:a.` https://trac.ffmpeg.org/wiki/Encode/AAC The above page says that effective range for -q:a is `0.1 to 2.0.` But, I tried to encode with `-q:a 5.0` and FFMPEG didn't gave any error for encoding the audio. I was suprised! And I got around 300kbps with `-q:a 5.0` So, what is the true effective range for VBR encoding i.e for -q:a with FFMPEG's Native AAC encoder ?

Hi All, How can I get ffmpeg to honor 'analyzeduration' and 'probesize'? I'm submitting "-analyzeduration 5772725000 -probesize 15091101696". Getting "Consider increasing the value for the 'analyzeduration' (0) and 'probesize' (5000000)". The terminal output is below.

DTS discontinuity
by Mark Filipak 25 Dec '23

25 Dec '23

Hi All, I have problems with stream 0:2 (the subtitles). The problem ruins to-SRT conversions later in the work-flow. Also, stream 0:2 winds up with no duration and that screws up concatenations. A typical notice is "DTS discontinuity in stream 2: packet 12 with DTS 12859568". I'm trimming, then concatenating the segments. I'm used to working in 'N' & 'DTS' & 'PTS' for the trimming and the concatenations. I'm successful for video & audio, but subs are creating problems. I'd appreciate some wisdom regarding how to fix the 'discontinuity' issues. I have not found a 'showinfo' equivalent for subtitles. The log below is a version I cooked up to show 'N' only for I-frames.

wanting to convert ripped DVD movies and TV shows to MP4 for Plex
by Alan Malmberg 23 Dec '23

23 Dec '23

I have hundreds of ripped DVDs in vob format that I want to BATCH JOB to single mp4 files WITH SURROUND SOUND for use with Plex server. Any suggestions? I see the above as doing one at a time. Mine are already ripped and removed DRM so just need to convert. But also don't want to have to create hundreds of folders and name them. Want the batch job to do it all for me. For example - - I am trying to find an easy (and free if possible) way to convert/reencode all my ripped DVDs that I ripped and removed encryption from standard .vob files in a VIDEO_TS folder by default. I would like to do this in a batch mode to a single .mp4 file that includes either AC3 Dolby Digital 5.1 sound or DTS if that movie has it available (both if possible). The datastructure on my drive is a Movies directory - - with sub folders for each movie with VIDEO_TS folder under that with the multiple .vob files in that folder. I went searching for it and multiple folks want to do the same thing as me, but none of the answers were a set it and forget it type batch file to do say 500 movies. Do you know of a way to do this?? PLEASE??? I only want to have to do this once if possible and not 500 individual conversions if you get my meaning. I can convert with Handbrake very easily, but is a ONE BY ONE process unfortunately (at least for TV). I decided to go with .mp4 as I wanted to use it for my tablets as well as I just set up a Plex server and my son is also doing the same thing so we can share. I want the batch job to create the file folders for me automatically and move the converted file to a different drive and directory from the original files that I want to keep INTACT!! I understand that MakeMKVBatch will DELETE the original files, WHICH I DO NOT WANT.... Anyone already done this and has a script that I can use for ffmpeg? I have also ripped a bunch of TV shows that have multiple episodes per disk. Can the batch script also handle those to separate out each episode to individual mp4 files for plex? For example - each disk of Leverage has 4 episodes and then multiple disks per season. How best to do that? I think I may have got the movie side almost done, but would still like pointers. The main issue now is the episodic TV shows that have been ripped. Thanks, Alan
