Q: Slow transfer from camcorder to FCE
Hello all!
I just got a brand new iMac, totally maxed out, hoping to speed-up imports, conversions, exports and encoding compared to my trusty Macbook Pro from 2009.
I find the transfer from my also brand new Canon XA20 camcorder to be awfully slow. When transfering a big file, the transfer will start up fast and fine then will gradually slows to a crawl after about a minute or so of importing. Short clips will transfer fast.
Transfering from the camcorder by USB or putting the SD card into the iMac SD slot won't change anything, that would seem to indicate that the camcorder and the USB bus are both fine.
Looking into Activity monitor indicate that the CPU and the disk traffic are both totally under-used for their capacity. Processor at about 100% (should max out at 400% for a quad-core, see pic) and inbound traffic from the SD card have peaks at 2 or 3 MB/s with some idle time in between.
Infos :
iMac 27, bought in april 2014. 3.5 GHz i7, 16 GB ram, 4 GB video card, 1 TB fusion drive, latest Maverick OS, latest FCE 4.0.1
Canon XA20, two identical 64 GB SanDisk Extreme Class 10 SD XC 1 cards at 45 MB/s, AVCHD files, stock firmware in the camcorder.
Any ideas?
iMac, OS X Mavericks (10.9.2), 3.5GHz i7 16GB ram 4GB video 1TB HD
