Hi guys, I am having a issue where all the clips that I convert have a chroma problem. The red is saturated on all clips and there are red horizontal lines in the chroma.
$ ffmpeg -y -i 5079162_NHL\ Marleau.mp4 -acodec pcm_s16le -vcodec prores_ks -profile:v 1 -copytb -1 -vf yadif=1 -qscale:v 10 mp4-yadif1-q10.mov I thought this might be the chroma bug but I have experimented with a couple of different options replacing yadif=1 with the following: -vf scale=out_color_matrix=bt709 -pix_fmt yuv422p10le -vf colormatrix=bt601:bt709 -vf yadif The yadif=1 option provides the closest results and specifying multiple options seems to make it worse not better. The problem is more obvious on a broadcast monitor. We are also having a problem where the converted clips are 1 frame shorter than the original, missing a black frame at the start of the clip. Here are the details of the clip I am trying to convert: $ ffprobe -v error -show_format -show_streams 5079162_NHL\ Marleau.mp4 [STREAM] index=0 codec_name=h264 codec_long_name=H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 profile=Main codec_type=video codec_time_base=1/50 codec_tag_string=avc1 codec_tag=0x31637661 width=1920 height=1080 coded_width=1920 coded_height=1080 has_b_frames=1 sample_aspect_ratio=1:1 display_aspect_ratio=16:9 pix_fmt=yuv420p level=41 color_range=tv color_space=unknown color_transfer=unknown color_primaries=unknown chroma_location=left field_order=unknown timecode=N/A refs=1 is_avc=true nal_length_size=4 id=N/A r_frame_rate=25/1 avg_frame_rate=25/1 time_base=1/50000 start_pts=0 start_time=0.000000 duration_ts=2354000 duration=47.080000 bit_rate=9081205 max_bit_rate=N/A bits_per_raw_sample=8 nb_frames=1177 nb_read_frames=N/A nb_read_packets=N/A DISPOSITION:default=1 DISPOSITION:dub=0 DISPOSITION:original=0 DISPOSITION:comment=0 DISPOSITION:lyrics=0 DISPOSITION:karaoke=0 DISPOSITION:forced=0 DISPOSITION:hearing_impaired=0 DISPOSITION:visual_impaired=0 DISPOSITION:clean_effects=0 DISPOSITION:attached_pic=0 DISPOSITION:timed_thumbnails=0 TAG:creation_time=2017-02-03T23:55:00.000000Z TAG:language=eng TAG:handler_name=Alias Data Handler TAG:encoder=AVC Coding [/STREAM] [STREAM] index=1 codec_name=aac codec_long_name=AAC (Advanced Audio Coding) profile=LC codec_type=audio codec_time_base=1/48000 codec_tag_string=mp4a codec_tag=0x6134706d sample_fmt=fltp sample_rate=48000 channels=2 channel_layout=stereo bits_per_sample=0 id=N/A r_frame_rate=0/0 avg_frame_rate=0/0 time_base=1/48000 start_pts=0 start_time=0.000000 duration_ts=2259840 duration=47.080000 bit_rate=253262 max_bit_rate=283875 bits_per_raw_sample=N/A nb_frames=2210 nb_read_frames=N/A nb_read_packets=N/A DISPOSITION:default=1 DISPOSITION:dub=0 DISPOSITION:original=0 DISPOSITION:comment=0 DISPOSITION:lyrics=0 DISPOSITION:karaoke=0 DISPOSITION:forced=0 DISPOSITION:hearing_impaired=0 DISPOSITION:visual_impaired=0 DISPOSITION:clean_effects=0 DISPOSITION:attached_pic=0 DISPOSITION:timed_thumbnails=0 TAG:creation_time=2017-02-03T23:55:01.000000Z TAG:language=eng TAG:handler_name=Alias Data Handler [/STREAM] [FORMAT] filename=5079162_NHL Marleau.mp4 nb_streams=2 nb_programs=0 format_name=mov,mp4,m4a,3gp,3g2,mj2 format_long_name=QuickTime / MOV start_time=0.000000 duration=47.146600 size=54956371 bit_rate=9325189 probe_score=100 TAG:major_brand=mp42 TAG:minor_version=0 TAG:compatible_brands=mp42mp41 TAG:creation_time=2017-02-03T23:54:57.000000Z [/FORMAT] _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
