- The P2 proxies have only 2 audio clips and no timecode which would popup a message in FCP when trying to reconnect the 4 channel hi-res files but this is still manageable.
- The worst thing is the different file name extension name, the proxies use MP4, the hi-res is MXF or later when ingested with Log & Transfer, it's MOV. This means a lot of manual reconnecting. With a bunch of clips it's a pain.
There will be soon a podcast here are creative cow how to convert AVC-I video to ProRes but keep it in the orignal P2 structure to send it to FCP using our software or even to reconnect it later to the original files or move it to an Avid that can deal with AVC-I. This workflow can also be used to create proxies which are easy to reconnect later.
If you can't wait for this tutorial then you can contact me through our website and I will give you some options how to establish a working low-res/hi-res workflow: http://mxf4mac.com/contact
