Accelerate CCE?? writing, different, matter, source

andy

Hi, I'm wondering if i could speed up the cce encoding a bit.

Does it matter if the source and working dir is on the same HDD or is it faster when source is on an other hdd than the working dir??

if you have low ram and your swap file is also on the same hdd, then writing to a different hd than the source will help slightly.. also swapping from a third hdd will help even more... even in low ram this will only help slightly.

if you have adequate to large ram then it will not make a noticable change. hard disk use is very light during encoding. faster cpu/memory will be more of a help than anything else. if you have cce set to use filters, turning those off will help. search the board, you may find some other tips.

Turn on logfile( it's in the options bit). This will give you a run down of the times involved in your encode. On my machine the biggest component is reading the souce file(Huffyuv), which after quot;extensivequot; testing is the fastest.

The best source for high speed is uncompressed (Black Magic 8 bit codec), but only if you have fast disk (eg. 3 SCSI disks array). Bitrate for this codec is about 20 MB/sec. If you want have 5 times realtime speed than your disks have to be able give 100MB every second.
If you have fast array+ dual Xeon 3.4 Ghz you can get up to 7times faster than realtime (quite impressive).
RAM is no important if you have 1 GB it's OK.
RAM is needed if you're trying encode eg. 500 clips in the same project.
Destination disk should be different than this one where you have source file.
