Answers.Body: <p>Intermediate codecs are intra-frame. That means that each frame is compressed alone.  The movie is like lot of JPGs in one file.  When you move the play-head, After Effects just needs to load the requested frame.</p>
  
  <p>H264 has lot of different formats in it, but most of them compress some frames like JPG, (they are called keyframes) and for the few other frames, it encodes just the difference relative to previous keyframe (movement, zoom, or other differences). </p>

Using this kind of codec in After Effects makes it less reactive because it is harder to get one precise frame. After effect must decode the previous keyframe and all the frames up to the one it really wants.</p>

Body: <p>I have a Canon 60D, which obviously uses the h264 codec for capturing.  I am using Adobe Premiere and After Effects -- and I've already seen how both can handle h264 footage natively (Thank you Jason Levine).  However, I've also seen footage that has been transcoded to an intermediate codec for editing (as opposed to a capturing codec).  This footage, to me, looks like it runs smoother in Premiere and After Effects than allowing the footage to run natively.  Unfortunately, these videos always fail to mention the name of the particular intermediate codec being used.  So finally we arrive to my question:</p>
  
  <p>What is a good intermediate codec to transcode h264 footage to, before running it on Premiere or After Effects?  </p>
  
  <p>I would appreciate a thoughtful answer to this question from someone who uses the Canon 60D (5D and 7D user input is also welcome) in a PC based Adobe workflow that incorporates Premiere and AE.</p>
  
  <p>Thank you.  </p>
