Further details are welcome as well.
On the surface, that sounds quite long. Now, are you talking about Export, or Rendering (hitting Enter to Render the Timeline)?
If Export, then what are the settings that you have chosen?
What Effects do you have applied?
As Harm asks - what CPU? AVCHD is highly CPU intensive, and a fast i7 is recommended.
I just saw a new build by someone, using a dual core Sempron 3600+ CPU, that is about 120 times slower than my machine, so depending on the processor, a one hour rendering time does not surprise me.
Yes. Many on the PrElements forum with vastly underpowered units do have issues with AVCHD. Too many resist admitting that they DO need a fast i7, or at least a hot Quad-core, to use that material. Here, the computers are usually a bit more stout, though not always.
Back in my hot-rod days, the adage was "there is no substitute for cubic inches." That rather applies here to a degree.
My CS5/AVCHD 1st Impressions http://forums.adobe.com/thread/652694?tstart=0 includes a description of my computer
I get a 2-for-1 time... where my 12 minutes of test video takes about 6 minutes to render from AVCHD to DV NTSC Widescreen
sorry forgot to put the processor info
core 2 duo 2.6 7300
i am exporting out as windows media 1080p
In comparison to my system only about 30 times slower, so my encoding times would be around 2 minutes and that appears very long. How many processes are running, according to Process Explorer, not Task Manager? More than 40 - 50? Clean up. Did you tune your services? Windows 7 Service Configurations by Black Viper Is Windows properly configured, UAC off, Search indexing off, Compression off, etc.?
I have visited black viper before and cut off recommended services. I believe it just comes down to building a beefier machine. i got a 2 years out of this machine and still makes a good photo editor.
thanks for all of the replies.
