Hi. When I scrub along the timeline, it's very slow and jerky. I have a really powerful computer and frustrated as to why it would be this way. I have set playback and paused resolution to 1/4 and still it's slow.
I had a similar problem before that was solved by turning off maximum bit depth in the sequence setting. Now however, I'm having the same problem with different footage but I can't see what could be making it slow. The footage meta data and the Sequence settings are below. So is the computer hardware I'm using.
Windows 7 Ultimate
Would that make a difference anyway?
With this media, probably not. AVCHD is no more disk intensive than DV, and you can easily get DV to run multiple streams from a single drive. It will be even less of a problem coming from a RAID 0.
The issue with AVCHD is the processor. But yours is much more than sufficient, even using software RAID. (You can easilly test this just by opening Task Manager and seeing your CPU usage when playing footage. Likely it is nowhere near maxed out.) So...something else is interfering.
(On a side note, a RAID 0 with tapelss media, for which you have no tape backup in the event of a drive failure, is not the best idea. Ideally you want a RAID level that offers some form of data security. RAID 3 is best, RAID 5 is OK, even RAID 1 is better than 0.)
Hi. Thanks for the feedback. When you say something else is interfering, is there anything you can think of? I keep a back up of all my data and projects on an external hard drive. I think it's raid 5. It's supposedly the most secure one.
I found out from the IT guy who built my computer that the Raid0 Drive is run by windows 7 software and not from the bios. Is this a problem?
By the way I hope I've interpreted the above message correctly. I'm pretty sure that's what he told me on the phone.

An OS level RAID configuration will not deliver the same performance as
a BIOS level RAID... whether controlled from the MB or a dedicated controller.
Even a mid-range priced RAID controller will provide
an appreciable disk read performance boost.
