I noticed that the video clips that I transcoded to ProRes (HQ, 422, or Proxy) using FCP7's Log & Transfer would eventually start stalling and failing to load properly in the Source Window when you do the VERY REPEATABLE steps below (I've been able to successfully reproduce the issue below on two separate iMac computers (older 2007 iMac & a maxed out 2011 iMac) running 10.6.8 and 10.8.4 respectively using various scratch drives. I tested it on both Premiere Pro CC and CS6 using ProRes HQ, 422 or ProRes Proxy clips with the same results, every time). HOWEVER, the same clips transcoded to the same ProRes format (HQ, 422, or Proxy) using Prelude do NOT have the issues below... which leads me to these three questions:
1) Why exactly do the ProRes files transcoded in FCP react differently (see how below) than the ones transcoded in Adobe Prelude, even though they are the same size, bitrate, etc.?
2) Why do the clips trancoded to ProRes using Log & Transfer in FCP generate Peak files when brought into Premiere, whereas Prelude's transcoded clips do not?
3) Why when I click on "properties" on a ProRes clip from Prelude it shows "Quality = Most (5.00)" but the ProRes clips from FCP's transcode show as "Quality = Normal (3.00)" ...the file sizes are the same, and the bitrate is basically the same and I can't see any real differences upon close examination...so what's the difference and why are Prelude's trancodes listed as a higher quality?
The issue with ProRes (HQ, 422, Proxy) files via FCP's Log & Tranfer:
I tested about 10 different projects (all containing 60+ ProRes HQ, 422 or Proxy video clips transcoded in FCP) and each had the same result which, after doing the steps below resulted in this "Media Pending" message:
Here's the steps to reproduce this issue:
1) Start a project and bring in at least 60+ different ProRes (HQ, 422 or Proxy) video clips.
2) Double-Click on each different clip in the Program Window so it opens in the Source Window and COUNT as you go.
3) AFTER you've double-clicked and opened up at least 20 different clips in the source window, hit play on the next clip. Then, stop it.
4) Continue on and once you've reached a total of 52 clips, it will suddenly hang and show the yellow message above!
5) You can either wait out the message which can take up to 15 seconds, or you can immediately scrub through the clip manually. But it won't play if you hit play until that message goes away. Annoying!
****6) This will continue to plague several clips following that 52nd clip making working with ProRes422 footage frustrating and slow at times.****
This slows down the editing process considerably having to wait for the "Media Pending" message to go away. Or having to manually scrub through those clips that lock on "Media Pending" so the message goes away. This issue did not occur when I worked with other formats like native AVCHD (.mts) files or ProRes files transcoded in Prelude. Just the ones transcoded in FCP. See my 3 questions above...
