  Codecs info change ?

  Posted by Roger Clark on July 11, 2011 at 2:43 pm

  Quick question,
  Even though I’ve transcoded my footage it still displays H.264,Linear PCM in my Codecs: box in the Inspector info.
  I’m trying to find the cause of my sometimes choppy timeline, which will disappear if I re-start FCP-X.
  I’m on a MacBook Pro , 2.66GHz Intel Core 2 Duo with 4gb ram and a Lacie 7200 rpm 320 GB partitioned external Hard Drive ( 100 GB available ) connected by FW 800. It’s a 16 min movie.
  Thanking you in advance, Roger

  Roger, I believe memory is fairly inexpensive now and it may help your overall performance if your Macbook was running with 8 GB memory instead of 4 GB. It still sounds like FCP X has some areas where it either can’t keep up with something that is contending for the CPU or there may be a bug somewhere that’s causing the temporary stumbles. Regardless more memory will likely reduce the chance of this happening.

  Thanks Rick, I’m going for more memory but I still can’t understand why the codec info does not change in the Inspector when I’ve transcoded it ?

  Did you transcode it outside FCP X from H.264 or did you transcode it as part of the Import into FCP X or transcode it some time after you had completed the Import?

  If it says it’s H.264 in the Inspector, what happens when you select a clip and try to transcode it (again)? Does it then tell you the code is already ProRes? If the answer is “yes”, that’s certainly a strange bug although perhaps there’s some hidden metadata that retains the original codec.
