    applying effects too slow

    Posted by Mike Tyler on May 22, 2017 at 8:23 am

    Hey,

    so I am editing some 4k footage, already got it down to 1/8 res, preview file format (in sequence settings) to P2 1080i and made 1080p proxies (which also took ages to encode in Media encoder)..

    I’ve also pre-render the in and out points. I get a fluent playback, but with adding effects (color correction) I have to wait couple of seconds to even see the result of my changes. And immediately as I move a slider, the green bar above the timeline turns to red again. WTF ?

    I am editing on a Macbook Pro Retina and usually things are pretty fast..

    So I guess I am doing something wrong here ?

    Is your media on separate storage, preferably a RAID array? What is your connection to that storage?

    Once you add color correction, every pixel is changed from any pre-rendering you had done.

    System:
    Dell Precision T7600 (x2)
    Win 7 64-bit
    32GB RAM
    Adobe CC 2015.02 (as of 6/2016)
    256GB SSD system drive
    4 internal media drives RAID 5
    Typically cutting short form from HD MP4 and P2 MXF.

    I did transcode to proxies.. this time I tried to ProRes 422.. again, the playback is smooth but color correction is lagging.

    Impossible that a 1080 ProRes422 file at 1/8 of resolution is doing this..

    Also, where does the pre-rendering from in to out point come in useful ? When anytime you make a change it gets reset..
