  • too long video trace file volume ?

    12 juin 2021, par david

    I have produced an XML trace file of a 20-sec video and the volume of this trace file is 8.57 Gigabyte !! the videos is encoded using this command :

    


    ffmpeg  -i  input_1080p60.mp4  -c:v  libx264 -pix_fmt yuv420p  -b:v 8000K -bufsize 8000K -minrate 8000K -maxrate 8000K -x264opts keyint=120:min-keyint=120 -preset veryfast -profile:v high out_1080p.mp4


    


    then I used the following command I changed the format in .264 because the input of JM software for producing an XML trace file is .264 :

    


    ffmpeg  -i  out_1080p.mp4  -c:v  libx264 -pix_fmt yuv420p  -b:v 8000K -bufsize 8000K -minrate 8000K -maxrate 8000K -x264opts keyint=120:min-keyint=120 -preset veryfast -profile:v high out_1080p.264


    


    after using JM using the following code :

    


    ldecod.exe -i E:\software\out_1080p.264 -o E:\software\out.yuv -xmltrace out_1080p_xml.xml


    


    it is really weird for me. because I have more than 1000 videos that I need to produce their trace files and I do not know what should I do with this size of the trace file. furthermore, I can not open a file with this volume and no software can open the file !! :((. could you please tell me what is the problem ? and how can I solve it ? do you know another way to produce this trace file ?
THanks

    


  • FFMPEG - 4K HDR - MPEG - BIG FILE convert

    8 mars 2018, par Ian Lodanko

    I would like to ask how through ffmpeg to achieve the smallest file size and yet keep the best quality [LIKE Youtube convert].

    Currently used :

    ffmpeg -i "/home/sampe_4K_HDR.mkv" -map 0:00 -c:v libx264 -preset ultrafast -b:v 66718k -pix_fmt yuv420p10le -x264-params "colorprim=bt2020:transfer=smpte2084:colormatrix=bt2020nc" -crf 18 -c:a libfdk_aac -profile:v baseline -level 3.0 "/home/sampe_4K_HDR.mp4"

    But the size of the video after conversion is very large, I would like to preserve as much as possible the quality of the original video and get the smallest possible video size.

    Could you please advise ? Write some examples of how to get better with smaller sizes ? Thank you in advance and I apologize for my English in advance.
