I grabbed canon-hf-100-1080p-psf.mts from the kdenlive/supported cameras site. I can load the clip and play it in kdenlive - looks pretty good. Here's the cli output: kdenlive QPainter::fontMetrics: Painter not active ALSA lib pulse.c:272:(pulse_connect) PulseAudio: Unable to connect: Connection refused SDL failed to open audio: No available audio device But with both conversions ( i.e as I did with rawvideo and yours with dnxhd kdenlive segfaulted as I opened the clip: kdenlive QPainter::fontMetrics: Painter not active kdeinit4: preparing to launch ALSA lib pulse.c:272:(pulse_connect) PulseAudio: Unable to connect: Connection refused SDL failed to open audio: No available audio device <unknown>: Fatal IO error 9 (Bad file descriptor) on X server localhost:14.0.
