Bill Gehrke Jun 10, 2010 6:27 AM (in response to sacha_G)We need two things:
- A true description of your hardware, stock Dell does not mean anything, especially the disk system.
- Have you tuned your OS? It probably has all sorts of uneccesary processes and services running. Get rid of all the Dell added garbage and use my Windows 7 Tuning Guide as a suggestion of setting it up to run more efficiently.

2. First thing I did was a clean install of W7 (Enterprise), I always start from vanilla install.
I'm a bit unsure about your tuning guide - can you document what improvements you get after changing said settings? I note the option "Adjust Visual Effects and check Adjust For Best Performance" is one way to turn off Aero (which I've tried anyway), which whilst sort of resolving the original problem, unfortunately now causes other display issues (and also caused CS5 to crash when using the source trimmer window) so have had to switch it back.
Turning off the services as you are suggesting seems a bit drastic just to get a plain DV clip without any FX to playback smoothly (e.g. CPU util is about 3% in these situations, network at about 5%, disk not doing anything).. it's the kind of thing I would have done about 10 years ago but modern machines are supposedly built around HD multimedia so it seems odd to still be expected to do this kind of thing now.
FYI, this was the thread that suggested turning off Aero to fix:
Out of interest, what do other people use to get full HD preview under CS5? Is it all OK out there in NTSC land @ 60fps?
Thanks

Harm Millaard Jun 10, 2010 7:37 AM (in response to sacha_G)Sacha,
Your disk setup could well be the cause of your problems, and then that single disk is filled with stuff that should not be there in the first place. Anything over 40 - 45 GB is suspect, anything over 100 GB is a giant ALARM that something is seriously wrong.
Only a single disk locally and a slow NAS on a single NIC connection is a serious bottleneck.

4. Re: Full screen playback jittery with Aero enabled
sacha_G Jun 10, 2010 7:50 AM (in response to Harm Millaard)Thanks Harm, but It's not that - I have got 4 x DVCPROHD/100 streams running simultaneously (and with 4 x MPE fx on each layer AND transparancy) with no dropped frames (at this point I gave up trying to add anything else!) - I've had the Editshare for 4 years now running happily without dropped frames on a whole variety of systems including an Axio LE (In fact our entire network and routers are configured for latency free high bandwidth editing) - 60Mb per sec max, more than enough bandwidth to play a single DV clip I'd say, and note that NIC is a server class one, as specified by Editshare.
The issue is that of the *full screen preview* being jittery, turn the preview off - fine, looks reasonable (considering I can't run 1920x1200 screens @ 50hz), Full screen on, preview drops every other frame and then some. Pans jitter consistently, like it's trying to do some weird frame rate conversion and ending up with a display rate of 23 and a half Hz with jitter.
Single disk locally is only an issue if you have video/swap drive on it - I have 12Gb RAM, that drive spends most of it's life asleep, believe me.
I imagine if I used a Blackmagic Intensity instead for my HDMI output *maybe* things would be OK - I'm just trying to avoid having to buy any extra hardware until I'd explored all the options first.
I'd raise a ticket with Adobe but I'm still waiting for my full license key!

5. Re: Full screen playback jittery with Aero enabled
sacha_G Jun 14, 2010 5:40 AM (in response to sacha_G)Ok - got my full licence key enabled - no improvement but at least I can now ask Adobe directly!
Also spotted this from the Avid forums, could be a coincidence but the symptoms look like they are having *very* similar issues - wonder if there is an architectural issue between Aero, the driver and the application all conspiring to to make smooth full screen playback next to impossible for PAL users..
http://community.avid.com/forums/t/74412.aspx?PageIndex=9
My final line of attack will be to connect all the monitors up via HDMI and set them ALL to 50Hz and see if that makes any difference since the system now has only one refresh rate to deal with.
Alternatively, anyone out there using a Intensity card able to use all the Mercury goodness AND get seamless full screen playback from the timeline with PAL framerate projects?

6. Re: Full screen playback jittery with Aero enabled
sacha_G Jun 14, 2010 10:47 AM (in response to sacha_G)Ok, answered my own question - it seems as I suspected that all monitors must be set to the same refresh rate - this is impossible for 1920x1200 unfortunately as no monitor will display that @ 50 Hz - that said I *can* display 1080p on them - bit of a shame as then I have to sacrifice 120 pixels on each of my main monitors - 60Hz NTSC folks - (e.g. most everybody else) will of course be running all your screens at 60Hz anyway and so will never have seen a problem....
If any other PAL users find a tweak to fix this, let me know!
