Q: Delayed video playback during editing??

i am having issues with my video being delayed while i am trying to edit it. i imported directly from my canon 60d. (i also tried importing it from my external drive; also have made an HQ and a 422 version.....which are extrememly bigger. why would they have these options when you cant even edit the raw video at a smaller file size??) i have compressor but noticed it does not have a LT version of prores 422 - which i had to google, and i have version 4. how can i import my video with a smaller file size while still keeping high hd? i dont know if the proxy option will reduce my quality or not, and is this even the reason why my playback is being delayed so much? i am new to fcpx and new to video editing on a higher level! i never had these issues with imovie with the same camera, etc. but then again i never tried to make it hd.

    The 60D records a highly compressed codec, h.264. It is not an editing codec. Depending on your project's complexity, it will may benefit from optimizing to Pro Res 422 (transcoding). You probably don't need Proxy to play well.

     

    Set your Playback preferences to Better Performance and use Original or Optimized Media. Export as H.264.

    Being of smaller size does not mean it will be easier to edit - in fact it is usually the opposite.

    H264 is very compressed and produces files smaller than ProRes 422, but the latter is much easier for your processors to deal with. That is why the term "optimized" is used, as it is optimized for editing.

     

    Plus, there are several factors (CPU, GPU, speed of HD drive connection, available RAM, complexity of the media, size of media,...) that influence how much a given mac can handle.

    For instance, when editing multicam your mac will need to fetch and decode several clips at the same time.

    In some cases, one may need to use "proxy" media, which is ProRes encoded, but small size and lower quality.

    thank you guys so very much!! i used ProRess 422 and it is working. thank you for clearing up the fact that larger doesn't mean that it is worse for editing. i appreciate it! and thank you Russ for explaining how to export!

    Same issue with choppy playback (stalls... hesitates).  Haven't been able to check FC settings yet.... but presumed it was a (lack of) RAM.  Or have we exceeded the processor's capability?  This issue just began with the use of the FC Optical Flow effect.

     

    MacBook Pro 2011 - Core i7 - 2.7Ghz - 8GB RAM - USB 2 connection to external drive with FC Library file running from there.

    USB2 has never been adequate for video. You need at least USB3 or Thunderbolt.
