Hi. I have a not so powerful PC now:
3200+ Barton
512DDR
7200rpm hard drivers
camcorder with DV IN

What would be the next config to edit DV video with simple dissolve between two clips, and one title track, REALTIME on firewire port?
Now it is only 5-10 fps.
A core2duo has enough power to achieve this?
I know edius can to this (even on my config), but i want to STAY in Vegas ;)

thx,
Marton

What preview setting are you using? My 3.4 GHz laptop does this now. My preview settings are on Preview (Auto).

I'm in Europe, so i use PAL DV settings. 720x576i, 50field/sec, lower field.
Preview in Auto setting is about 12fps, and Preview in FULL
setting is about 9fps on my camcorder LCD.

So you say a 3.4ghz real P4 (not celeron) processor can do this job?
25/30 fps with dissolve and a title on firewire port? If yes, the core2duo
has also enough power.

Yes, for simple crossfades I typically remain at 29.97. Disk access can affect this somewhat as well. Adding effects will also affect this. And, yes, it is a P4 (not Celeron).

That is part of your problem. Change you preview setting to "preview" instead of full. Or buy new hardware. Unfortunately that seems to be the only options.

Do you mean in project properties under full resolution rendering quality?
When i set it to "preview", the output on cam. lcd is also jumpy, 12-14fps.
There is no "full" setting, as you say.
"Full" is above the preview window, but its call "preview(full)" and "preview(auto)". i dont know exactly what do you say. Both of them produce 10-12fps.

"Or buy new hardware"
Yes, that's why i started this topic.

If you're using one of the newer versions of Vegas with scopes, make sure they aren't doing real-time update.

Check that opacity is 100% on the event and on the tracks.

Check that there aren't any FX being applied, at the event, track, or video preview FX level.

I believe the 3200+ barton should be able to do RT cross dissolve.

2- A core2 duo should have no problem with this... it will be a *lot* faster than what you have. At least four times faster.

Glenn thanx.

I use Vegas4, no scopes, no FX, and opacity is at 100%.
(if u say, vegas4 is old, i have tested vegas5 and 6 trial also..)
Every settings is OK, i'm sure, i use vegas for long time..

"I believe the 3200+ barton should be able to do RT cross dissolve."
Realtime, realtime, but not 25 fps on I-link.
Of course on pc monitor there is no problem, its 25fps.

Preview (auto) usually (depending on how many effects or other processor-draining things are applied to the video) doesn't look so bad that you can't get a sense of whether something works or not, and will usually give you a decent playback rate even on a slow computer.

I have tested both mode.

In #3 i wrote:

And again: there is noone fx, opacity change, speed change, etc. just simple dv avi files with dissolve.

Just make sure you don't have many other programs running in the background. Other than that, it sounds like there's not much more you can do short of upgrading your hardware.

No, with clear win install the situatios is the same.

[QUOTE=it sounds like there's not much more you can do short of upgrading your hardware.[/QUOTE]

yes, i need upgrade, i know. i created this topic for this. what config can do my need?

All I can say is that I'm still running a 2.4Ghz Pentium with 512MB RAM (I had more RAM until recently when I blew a chip), and I have no problem playing back most moderately "effected" video with crossfades, etc. at the preview(auto) setting at real or near-real frame rates.

I'd say you should just upgrade as much as your wallet will allow. Even a small improvement will help with you're trying to get, I'd bet.

That's interesting for me, because i think
Barton 3200+ and P4 2.4ghz is about equal.
Are you sure that its realtime 29fps on FIREWIRE output? Not on monitor. On TV!

I dont think its a RAM issue. I can buy 2GB ram, and still have 12fps, and i think a core2duo config can do 25 fps with only 256 ram. (if i have such a system, i will test it)

Hi Prech!

Just some more feedback on my ASUS P4 + 3.2 + 2gb RAM.

This through firewire to external pro-monitor widescreen display: PAL Widescreen - 1sec Crossfade (Clip A and Clip B have Pancrop adjustments too!), with Preview Window sized at 401x221 display:

25 fps - FULL; Simulate Device Aspect ratio; Scale Video to fit Preview Window; Display frames in video preview window during playback=OFF

23>24 fps - AUTO; Simulate Device Aspect ratio; Scale Video to fit Preview Window; Display frames in video preview window during playback=OFF

Now, with any Previewing, I've found FPS rises the more LOOPS/passes I do. So, sometimes a 3pass CROSSFADE pass gets to 25fps where a SINGLE pass wont.

There are far too many variables for me to consider to adjust Preview, Preview window size, Show Frames or not, for me to worry about. If I want to "see" a crossfade and how it develops then 1>3 passes normally gets me to 25fps . .and then I move on.

As has been said, Prech, it is to reduce ANY process that is eating away at CPU power.

And so, it is on this basis that I have purposefully designed WORK Layouts that reflect my needs - at that time!

For example I do have layouts that are "missing" anything that will eat CPU - NO Scopes which are updating; A small or smaller previewing screen and in fact my "No1" or first Layout is - including the TOOLBAR and the STATUS bar:

* Trimmer

* Video Preview

* Media Manager

* Audio & Vid Bus

* Show Envelopes

* Active take

* Waveforms

* Event Buttons

* Event Fades

This is a really "stripped" down Layout. The point I'm making here is that I have designed my layouts around getting Vegas responsive in the way I want and work. I accept what Vegas can and can't do, and adjust accordingly.

Now sure, IF you upgrade, it will swallow up your CPU requirements. BUT you may very well come to a point that you TOO may need to adjust-back a Layout that even then will be sticking at a FPS that you aren't satisfied with.

Use the multiple Layout options to have the layout that will remove - for that session - unwanted and CPU intensive stuff - yeah?

After all, they are only a key stroke away? You can aways go back to the other layout quickly! - PLUS here is your chance to experiment with various CPU intensive layouts and quantify just what you are getting - or not.

Hope this helps - g

Today i make a new test.
Vegas4, PAL project, PAL DV AVI on the timeline (the file is on separate 7200rpm drive), no scopes, no opacity change...

My goal is 25fps on external PAL monitor.

The native dv avi file play smoothly of course,
But when i apply a simple LEVELS FX (because the shot was dark),
the video is 13 fps in preview(auto) setting, and 10 fps in preview(full)
setting on external monitor.
And!...
The task manager says: my athlon processor is never above 80%!
in both case.

So i'm afraid this is not a processor issue? Maybe my new core2duo config also cannot make 25 fps with simple levels fx? (or dissolve..)

(I have the firewire port on Audigy card, but i don't think this is the problem.)

Is your hard drive in PIO mode, or ATA? (Sorry, I don't know the instructions for checking this off the top of my head.)

Of course in ATA 100.

I believe he meant PIO or DMA mode? You need DMA mode.

Well, me too :) Ultra DMA mode is used.
I use PC since "80286 days", so i know everything is right in hardware side..

Hi. Today i make a new test with this config:

Biostar mainboard i965
E6300 Core2duo
1GB DDR2-800
160GB Maxtor Sata2
7300GS vga PCIe
PCI Firewire card

Clear XP SP2 install, with mainboard driver, sound driver, vga driver.

Vegas4.0d, PAL DV project, no scopes, no opacity change, etc.. everything in normal. I capture 2x1 min. video from camcorder.

When i make a dissolve between these 2 clips, on External monitor fps still NOT 25, just about 18-20 fps, and the video is not smooth.
The processor usage is about 50-55%, so i realize this is NOT a processor, and NOR a RAM issue! It's Vegas code!

I still love vegas, just :((((

Maybe Vegas 7 use the full processor speed, dual core or SSE2?
And i can see real 25fps on external monitor?
Can anyone confirm this?

I answer my question:
vegas7d trial can also produce only 20-21 fps
on external monitor in crossfade between two clips :(

Sony, please write a better code!
