When editing with very large files, it's a standard for us to use low-res proxies during the edit, then relink to camera originals for export. Especially as video specs increase and more cameras shoot RAW / ProRes out of the box, this is becoming a hard requirement for fitting Descript into our post-production pipeline.
There are workarounds by exporting from Descript to XML, but that introduces the need to conform the cut in Premiere / Resolve / whatever we're finishing in. We could transcode the raw footage to lower bitrate files, but that introduces generational loss of data when we export the sequence from Descript.
Proxy support would solve these pain points and would make Descript a much more attractive offering for higher quality productions.
