FFMPEG Concat DNxHD-Files : wrong duration of output-file
4 mai 2020, par ThomasI have AVID-DNxHD-files created by Ikegami EditCamHD and FFMPEG-coded DNxHD-Files.



Ikegami-Files are 1080/25psF at 185MBit/sec (10Bit). FFMPEG-Files are crated with this command :



ffmpeg -loop 1 -i c:\pics\VideoNichtVorhanden.jpg -s 1920x1080 -r 25 -t 92.8 -c:v dnxhd -b:v 185M -pix_fmt yuv422p10le d:\MissingFiles\missing_0001.mov

When I concat for example one .mxf with one .mov and another .mxf at the end, the duration is frong (about 26 Miuntes when it should be some 4 Minutes or so) and VLC-Player gives a Framerate of a very slow framerate and the video does not play the ffmpeg coded part.

The Ikegami and ffmpeg-coded files for themselves are playing great and do show the correct fps in VLC.



I can see in the probe-logs the



"codec_time_base": "20268137\/1351040"




and



"avg_frame_rate": "1351040\/20268137"




What is going wrong here ? How can I improve the coding-part and / or the concat to get a good result ? Is it only possible with re-encode instead of c:v copy ?



Any help welcome, thanks in advance,
