edit proxy workflow with Sony XDCAM (MP4)
We currently have around 450+ TB of footage shot in Sony XDCAM EX3 (MP4s).
We do not have space to store all the footage online, so we have archived it to LTO 4 tapes. We are about to move to new cameras which shoot in Sony XAVC (MXF)
We want to generate lo-res proxies for all these videos and store on a NAS and use for searching/tagging within our MAM (Axle). We are also thinking about having the option of editing (in Adobe Premier Pro) using the proxies, and re-link to the originals based on the EDL or XML.
Each of our archived BPAV folders corresponds to one of our events (which is usually around 1 to 2 hours long). For 80% of our work it is convenient for us to edit the full event in one sitting. That means that we would need to have a single proxy file which corresponds to the full BPAV (not have many proxy files corresponding to the individual MP4 files inside the BPAV - otherwise it becomes very tedious to align all the clips (esp. for multicam work) , since we lose the time-code connection between clips).
Can anyone tell me the best way of doing this - that can be automated. I cannot find any tool which can do this BPAV to single proxy (ProRes) file conversion.
We are also just about to begin a project to migrate all our video to LTO-6 tapes. Would it be a good idea to convert these to Sony's MXF format as part of the migration process? Would this be more suitable for as a long-term archival format?
Or does this workflow even make sense? Would we be making things too complicated? Would we be better off just making proxies of the individual MP4 clips (for preview alone), and pulling the full hi-res files from the LTO for direct editing in full-res. The reason why we are looking at proxy editing is to save time - since it may take some time to retrieve the originals from LTO tape and send over the network - and our editors have to work on very tight deadlines.
Would really appreciate hearing from anybody with experience in this area.
