are you planning on grading in resolve? finishing in premiere? dcp? premiere only supports rec.709/sRGB d65 gamma 2.2 so arri color would be clipped down to that. that’s why some xml to resolve. but if you plan on finishing in premiere,
you only get srgb output so you’ll lose the larger color gamut.
pluraleyes works a little easier than premiere for sound syncing. you’ll need to decide up front if you’re going to use proxies, transcodes, offlines, color pipeline, ACES, storage, backups, matching timecode/matching audio channels.
You’ll want to choose good DIT/dailies software solutions and test it all the way through the whole process something like Colorfront Express Dailies, hedge, shotput, or something with built in CRC support. Often its DAY-shot/scene-reel-take or something similar. The proxies(if used) will also need to support metadata as well. Premiere has problems with multicam audio syncing vs proxies, so afaik they haven’t fixed that yet. resolve has an audio sync feature as well.
