I tried this command line on an HD recording from an old BBC RedButton_HD DVB-T2 and it produced a vlc-playable file. I suppose Google would have found complaints if kdenlive was failing to transcode, but I have seen failures earlier because of other changes in ffmpeg syntax. I stopped the transcoding early. I haven't tried running kdenlive yet. The input filename here is unrelated to that of the original recording, and I'm not recommending use of this command line! Good luck!
