hi

 

I would like some more info about the import media proces in FCPX

 

when/why is 'create optimized media' neccecary?

 

I don't know if I must set this setting ore not.

 

I always set 'create proxy media' and 'copy files to FC event folder' to ON

this I can understand why

 

But when 'create optimized media' is on, FCPX takes a loooooong time and muuuuuch space.

Is there anything that works better or faster when 'create optimized media' is set to ON?

I do not understand why these oversised files would be helpful when editing...?

 

for example; a few days of skiing with friends results in +100GB footage.

when set 'create optimized media' to ON, I must wait extremely long to convert, and also the space on my macbook pro is too small (750gig, 500gig free).

when using an extarnal disc, the editing proces is far from smooth.

 

I use almost always '.mov' files

taken with HD action cams (drift), Iphones,...

 

thanks in advance

    If you find that you can use your native footage OK stick with it.

     

    If it doesn't work well when doing simple editing you need to convert ("optimise") to ProRes422 which is more suited to editing.

     

    If you are doing very complex editing involving numerous effects and tracks you may find you are dropping frames. To prevent this you should use proxy media.

     

    The Reasons:  Highly compressed footage like AVCHD is not good for editing as it puts a tremendous strain on the processor apart from other potential problems.  The processor has to decode every single frame.

     

    Converting it to ProRes makes huge files but the processor can whip through them effortlessly.

     

    Think of it as being a bit like the gears on a car or bicycle. When you are going up a hill, a high gear with the enguine/feet moving slowly is incredibly difficult to use but a low gear with the engine/feet racing around is much easier.

     

    The large ProRes files are a bit like the fast turning engine in a low gear  .  .  .  they put less strain on your computer  .  .  .  even though they take up a lot of space.

    ok Ian

     

    thanks for the quick response...

     

    one more question,

     

    i do not understand that even the proxy media is even bigger than the original?

    I understand that the proxy is smaller... maybe it's just smaller than the prores422 and still bigger than the originals?

    thanks

    I've never used proxy material and most people never need to.

     

    So unless you are having problems like I outlined above, you can forget about it.

     

    It is probably larger because it is much less compressed than the original and therefore easier to use.

     

    However, it is of very low quality and in the end has to be converted back to a high quality when you export your project.

    ah ok

     

    now I understand

     

    I'l stop converting to proxy and optimized.

     

    I'ts too much time and disc space consuming

    and normally, I think, there are no problems when using .mov files and a new powerful macbook

     

    thanks Ian!

    The main rule to apply is, "does it work well for me?"

     

    If it does, stick with it.

    exactly!

     

    I always left proxy and optimized ON

    but now I have always more and more footage of each event.

    I'ts not normal anymore how long I have to wait to begin (properly) to edit.

     

    when my brother, who works in the graphical business, started laughing with me, (he uses something from adobe and is pro windows) I was thinking there was something wrong.

    Importing on the adobe program takes only a few minutes...

     

    so, I'm gonna set the setting 'copy files to events' also OFF

    If I store the files from befofore the import at the right location, also there no waiting tima anymore...

     

    thaks again for the clear explanation Ian!

    update

     

    smoot working with FCPX is impossible on my macbook with the original hd files.

     

    use of the proxy files is really neccecary

    (the optimized files work also, but the eat up too much disc space)

     

    but now I know the difference between the two file types

    the optimized files are not that important for my type of editing.
