The expected behavior should have been that the output file size should have decreased by 3 times as we are going from 24 bit rgb to 8 bit grayscale, but it stayed the same. ffmpeg doesn't use the CLI encoder binary, but links to a library. Now I just need to figure out how to make Automator work. How can I check if my ffmpeg is using 8-bit or 10-bit version of the libx264 library?

(Again) I usually encode my media in the source's bit depth (8bit -> 8bit, 10bit -> 10bit). I've been trying to find a way to regulate the pix_fmt and bit depth process better and its been very challenging but this update includes reading the bit_depth from ffmpeg -pix_fmts and includes definitions for some of the decoders for a 'max' depth so that decoders that aren't compatible with certain pix_fmt sources should be filtered out, if you want to give this a try you Assuming a bit depth of 8 bits per sample, it adds up to 32 bits for every 2 pixels.

Without hardware acceleration, a typical command would be ffmpeg -i input. As with SR conversion, a naive approach to bit-depth reduction results in a kind of distortion, but this kind of distortion is generally considered less obnoxious. Referenced by Apparently you needed to "mix cpu and gpu in processing 10 bit color to 8 bit, which means you cannot ask ffmpeg to use CUDA hardware acceleration" according to the one that helped me. 16 means 16 Bits per sample le means "little endian" coding for the samples You can see a list of supported sample formats by inspecting the ffmpeg The "bit depth" in PNG refers to the bits per sample, not bits per pixel. , 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA 17 */ For some reason when encoding with hevc_nvenc (I use an NVIDIA GTX 1660 Ti GPU), ffmpeg (the command line tool) changes the pixel format to a 10 or 12 bit variant (p010le, gray12le, yuv420p10le, yuv444p12le, ), but I would like to keep the full 16 bits, since this affects the quality of the depth stored. After the -pix_fmt=p010le is removed, the green screen of the transcoding output is displayed. Then choose it with the -resampler option: ffmpeg -i input. wav I use ffmpeg to record xvfb desktop with 24 bit color depth and save it in gif format (and then I pipe it to AWS so you can replace the ' -' symbol with a filename. The solution to this distortion is to add "dither", which is a small amount of noise. 00008 * 00009 * Libav is distributed in the hope that it will Bit depth # However, FFmpeg defaults to 16-bit encoding when outputting WAVE, and will therefore not preserve bit depth of your audio file, if it is greater than 16. You can add the -c:a pcm_u8 input option if you want to force usage of the pcm_u8 decoder if you are convinced the device outputs PCM unsigned 8-bit. If you don't specify -acodec it will default to the muxer's default audio codec, which is pcm_s16be for aiff files, and that codec does not support all the bit depths you want. If the input is 16 bit or lower, then 16 bit output is chosen, else 24 bit.
