Andrew Devis, where would you find that tutorial you mention please? I’d also love to know how to delete multiple tracks at the same time

Jeff,

Hardware acceleration is on, yes.

When I analyze before defragging they all say 0% fragmented except the OS disc which says 3% so does this mean I don’t really need to defrag them?

In terms of clearing media cache I try to do it manually by locating the folder and deleting all of the temp files. Not sure when I last did it but can’t really do it either way now as I’m half way through a large project but I know it’s not a case of not having done this for ages as I try to do it regularly.

All I can think is the drives are a bit full up but they’re not *that* full… really quite stumped.

Editing tonight for a few hours and it confirmed the problem is the pause before the output or clip window shows the video after moving the slider along, it’s REALLY slow a lot of the time.. much slower than my lower spec PC in another office that’s whats confusing me

[David Payne]

thanks Jeff. Ok so I’m on the pc at the moment. Spec is:

Intel i7 950 3.07ghz
16gb Ram
win 7 64 bit
Nvidia GTX 570
HDD’s you know about.

The issue is relatively minor but would still like to get it sorted if possible and I have another slightly lower spec PC to compare it to that and one is MUCH better,

I constantly hear hard disk activity.. it never stops even with indexing now disabled on the 3 video drives.

When I scrub along a timeline the video doesn’t change in the playback window particularly quickly at all. If I click to a certain point in a timeline or indeed a clip in the preview window it takes between half a second and 2 seconds for the video to change. Occasionally when playing back long timelines the video freezes altogether for a few seconds and audio continues. If I pause and resume then it sorts this out for a short time until it does it again.

The 3x video HDD’s all have about 20% free on each.

Would love some suggestions to try! My cache files are saved to the default location on the same drive as my OS and premiere installation folder, not sure if changing this will help?

Thanks very much

Jeff, thanks for the tip and I will post tonight the full details. Changing this indexing thing will not remove/change any of the data at all will it? I have lots of video (AVCHD .mov files from canon 5d mkii) still to edit on there or already partially edited

[David Payne]

do you think it’d be worth the hassle to reformat and change my HDD configuration using my existing SATA drives to the one that Harm recommends in this post, or just plump straight for the SSD’s and do it all in one go?

i don’t have any raid set up. I did initially and start up time increased to over a minute so I abandoned it

hot off the press, this saves my bacon, hope it does for someone else too

anyone got any ideas on this I’m really keen to get this resolved. thanks a lot.

From a very knowledgeable source on the subject:

The video cards themselves don’t have the Optimus Technology, it is the laptop that will have the Optimus Tech built in to support the NVidia video card. When a laptop manufacturer supports the NVidia graphic cards, they add the Optimus Tech to the laptop so when the customer plugs in the NVidia video card the Optimus Tech will be in place.

So when you buy a laptop, check to see if it has Optimus Technology.

Laptops come 4 ways:

1. The laptop will come with BOTH a NVidia video card and a integrated video card. Most of these have Optimus Tech.

2. The laptop will come with just the NVidia video card chipset built-in to the laptop and there is NO other integrated video chips. These don’t have the Optimus Tech.

3. The laptop will come with the built-in integrated video card chipset and you can upgrade the video to a NVidia video card. These generally do have the Optimus Tech.

4. The laptop will come with an integrated video card chipset and you can NOT add any other video card to the laptop. No Optimus Tech here.

As far as what video card to recommend that will depend on the laptop specs.

I have recently found out that you need to avoid the laptop having Optimus Technology (an Nvidia thing) to get GPU acceleration in most cases and all of the laptops on the site I was looking at have this..

This search is not going to be easy by the looks of it.
