I’ve made a living as a software developer (MS technologies) for 30 years, and it just now occurred to me that it might be helpful if I gave you exact steps to reproduce. I sent the details below to Dmitry but thought it might also be useful to include them on this thread for completeness, in case anyone else from BMD is looking at the issue. However, it struggles with the file from HyperDeck, copied straight off the SSD (to the same target folder that the Fusion render is in), stuttering in playback.ĭoes anyone have any information on what's different with the DNxHD saved by the HyperDeck, and why Resolve has such a hard time with it? I'm running HyperDeck 4.4 and thus should have the latest version of the codecs. Resolve plays the rendered file from Fusion normally. Windows file properties shows a comparable data bit rate on both files, ~240,000 kbps. I bring this footage into Fusion, key it with Primatte, and render it back out as DNxHD, quality 100%, bit depth automatic. There is only one selection in the HyperDeck utility for this codec, and it's not clear what the specifications are.
I have the HyperDeck configured to record DNxHD. I hope this info helps others who encounter this problem. Dmitry's suggestion above to reduce the channels to a single stereo pair solved the problem. The problem was identified as the fact that the HyperDeck writes out the QT file with 16 audio channels, and this caused the playback problems. Using footage recorded in DNxHD Quicktime format from the HyperDeck Shuttle 2 wouldn't play properly in Resolve. Here's Dmitry's suggestion, which was quick, easy and effective:Īfter bringing the DNxHD in the Resolve session consider using a context menu called clip attributes and change the audio tracks and audio channels of this clip to 2 in a stereo config.
It's a very simple fix to the issue of Resolve struggling with 16 audio channels. With many thanks to Dmitry from BMD, the problem has now been solved in a way that doesn't require me to transcode via ffmpeg before use.
