do you think its my 'on board ram' that is too small?

**tingsern** · 08-03-2009, 04:07 PM

Windows XP 32 (Home) can only address a maximum of 4GB. It is less than 4GB normally - usually around 3.2GB - depending on the VGA BIOS and other BIOS settings. So - even if you increase the RAM - it is useless in this config.

Can you go Task Manager, under Performance and tell us what is the CPU and memory like when you do your EDIUS tasks?

Are the drives configured as a RAID? External drives often fail here.
I'd say it's the bus speed, not the RAM.

As I stated in one of your many threads about this...it was possibly an inadequate subsystem.Meaning hard drive throughput. If you are unfamiliar with these terms, do a search on the web for these answers. Learning these and other terms, and what they do, will help you down the road.

If he is editing HDV natively, then disk I/O is probably not the bottleneck since HDV is only ~25Mbps.

My first guess is that the GeForce 7600 GT can't handle the GPU effects, it normally only has 256MB of RAM and probably needs to swap to system memory, which is slow.

My second guess would be the CPU -- converting from HDV to Canopus HQ would help in that case.

He is saying he can't edit HD. No mention of effects stopping the
system. In general, I found that 1440x1080 would pass on 256mb of ram on the
video card. I do agree 512 to 1gb would be best.I don't think it is the processor. I have a 2.4 doing uncompressed
HD. His other posts specifically stated he was using HQ.

Using Usb drives to edit HQ will bottle neck easily.
Read a few of his other posts.

Read his post again.

its fine with HDV if you don't add any effects, but as soon as you add effects it seems to start to struggle.

Struggling and stopping are 2 different things.
We also need to make sure if he is calling hdv as mpeg or
HQ. That is why I mentioned to read his other posts.
I do agree with the video card being underpowered.

Also is he pre filling the buffer on the effects that
make the system "struggle."

**THoff** · 08-03-2009, 09:38 PM

Nobody besides you mentioned stopping. Read what I wrote again -- I doubt the GeForce 7600GT can handle effects in realtime because it a) isn't a very powerful GPU, and b) typically only has 256MB of RAM and is thus forced to the swap frame buffer contents with system memory, which is very slow and prohibits realtime performance.

If playback stops, then change the playback preference so it doesn't stop on dropped frames. It may then no longer be realtime, but at least it will keep playing. If that is not acceptable, render.

Regarding your second point, my advice was conditioned on HDV being edited natively, that's why I started my post that way.

**AJL14** · 08-03-2009, 09:49 PM

Sky - here's a real quick question, and it may sound silly, but I've head worse. Is your audio mixer open on your monitor? This will make all the difference in the world, since when the monitor is open the buffer will never fill enough to edit much HD. CLose it, if open, and see thedifference. Hope it's something simple like that - because I was editing HDV with a 2.16Mhz dual for years, and it was OK down to 3-5 effects.
best of luck,
Alan

You are also assuming this guy knows what
he is doing. No offense to OP. Knowing how
to set all of that up I believe is beyond his
proficiency level. That is why I asked you
to read the other posts to at least see the skill
set the OP has. That is all, you seem to think
that I am not in agreement with your asesment.
I totally agree but was trying to keep from
insulting the OP.That's all.

His system is very close to my old system and it struggled with Native HDV once any filter was added.
The only way native will work with filters is to use a Quad processor and even then the RT is reduced dramatically
I agree with you Thoff, he must convert to HQ, his processor and system will capture in HQ so this is the way he should set up, and he seems to have adequate disk space
For reference HQ takes around 4 time the disk space

Sky in the BIN right click on the captured clips and select convert and the directory to save to and also set your project up so your "RENDER FORMAT" to CanopusHQ, there are three settings I use "FINE"

Keep in mind that using HQ not only requires more space but more throughput as well. The USB drives may, or may not work with the HQ and effects.
Here is a link to one of his earlier threads about HQ on his machine.
This is where the 'stopping' phrase came from.

**Bluetongue** · 08-04-2009, 07:33 AM

I use a USB drive with my laptop and have no problems, the throughput measures 52Mbs considerably higher than HQ requires and captures easily so I assumed he would be OK

I also use an external RAID on Firewire 800 and that measures 95Mbs
Both using Diskbench

HQ takes the load off the processor, throughput required in HQ in Fine seems to be around 18Mbs and with a Slow processor I feel is the way to go

There is no reason to remain in "Native" as the moment a "Cut" is done on a clip or two clips combined on a timeline the whole timeline has to be re rendered for output to maintain the MPEG Structure anyway
