Also ensure you have 'Use optimised media when available' checked at the top.
To create proxy files right click on your clips and select 'create optimised media'. The files are only downres' for editing purposes and when you render out your final project it will be full resolution again. This allows you to work with downres's files and give you a much smoother editing experience. It also changes the codec since straight out of camera h264 are highly compressed and do not play back very well - compared to say Prores. Proxy files are basically downres'd versions of your straight out of camera files. It's always better to edit with proxy files when editing 4k footage (unless you have a very powerful machine).
So here are two ways to perform a lossless conversion of MKV into MP4.Davinchi resolve is not as well optimised as some other editing programs for playing & scrubbing through 4k footage, although it has been vastly improved with recent updates. I guess their justification is that they only need to support the formats that cameras record in.Īnyway, given I was working with H.264 video and AAC audio, I knew I should be able to put multiplex into a MP4 (or even MOV) container to make it compatible with Davinci Resolve.Ī quick Internet search found crazy posts and videos where people are using tools that perform a lossy conversion, or and perhaps even worse installing "special" software to do the job (which could contain some form of malware).įrankly I don't want to be installing special software, not when there are open source utilities that will do the job, utilities I already have installed on my computer. For what it's worth it looks like other NLE software like Adobe Premiere Pro does not support it either. Shame on them, I would have expected them to adopt open standards like Matroska.
Unfortunately the Davinci Resolve media pool just ignores files with that extension. MKV files are my go-to container format simply because of the convenience, given that there are utilities provided for muxing/demuxing and it supports any video or audio formats you want to use within the container. Recently I discovered that Davinci Resolve (NLE and Color Grading software) is incapable of reading MKV ("Matroska" multimedia container) files.
