    ProRes 4444 transcode speed

    Hi all, 

    Apologies if this has been covered before but am wondering how much the MC version bears on the transcode speed, in this case of ProRes 4444 .movs.

    I'm running 7.06. on an old i7 homebuild with 8GB ram, rushes are only on USB3, a far from an optimal configuration, but it works fine usually. However I'm getting very slow transcoding on these 4444 files, and CPU usage is only 20% across the 8 cores.

    I had been worrying that upgrading to a later version (such as 8.9.x) would result in less performance but would I get more transcoding speed?

    Any thoughts gratefully recieved!

    Ollie

    Well I took the plunge, it's almost double the speed, a great improvement! But still very slow, on half quality a 30" clip takes about 2'30.

    Are you transcoding back to the same drive or to a different drive?

    I tried all configurations, it was marginly better going to a different drive.

    Just had the second drive delivered from the shoot and it's flying in now, realtime! Identical model of drive, so either a duff port or drive. Thank god for that.
