New Laptop Video Not Happy.

CaptainPants · Post by **CaptainPants** » Mon Apr 30, 2007 22:10

Hey everyone,

I've looked around at all the different VJ softwares and really love resolume, but I have one big problem: Playing video is jerky. At first i blamed my old laptop which was a 1.1ghz Pentium M with 1gb of ram, but now with my new laptop: http://www.costco.com/Browse/Product.as ... d=11195984

I really thought that a Core 2 Duo 1.73ghz with a 1gb of ram would be enough, but the video is still just as bad as when I was on my old laptop. Please let me know what I can do. The clips I've tested are divx and the resolutions are setup to match the output of resolume.

Thanks,
Captain Pants

try an indeo codec. i find this is the better codec of them all for resolume. there is one on the download page that is osmething like pcvideo or something like that.

what fps and resolution are you using?

also a question that i would like to ask is does FPS affect video play back and performance of your machine?

If you just have a little mess around with different codecs you might come across one that is right for you.

I also noticed that you said that you are matching your output with that of resolume...

say your clips are 720x576 and you set your output in resolume to that. because its a big resolution it take up a lot of memory and can be slow.

also what do you mean by jerky?

keep us posted on it!

From what i can see off hand its down to whatever resolution your playing, the amount of RAM and most of all the Hard Drive.

Your main problem i would guess is if your using that internal HDD at anymore than 640x480 with 3 layers your not going do it. Its 5,400RPM which is very slow (in HDD terms). YOur after at least 7,200 which only come upto 100GB if im right at the moment. You gone for space over speed which is wrong decision. THere is a simple answer though, You need a eSata express Controller card (HERE) and get a 2-bay eSata Raid enclosure from Visualux (not too pretty but best on market) and put 2 500GB 7200RPM Sata-2 Hard drives in them. I worked it out at Â£250-Â£270 (Rip Off Britain) so if your US i'd guess at about $300-$350. Thiis option gives you a VERY fast external HDD at a much lower cost than 10,000/15,000RPM options and also ALOT more space. Maxtor HDD have the best multitasking performance whereas the Western Digital RS2 Hard Drives are best all rounder's at the moment

Next yout memory, 2GB is obviously better than 1GB. See if its possible just buy another 1GB stick or you may have to buy a complete 2GB Kit outright due to lack of slots. But i think your Hard Drive is your main problem, Trying to get 3 lots of information from 1 5,4000RPM HDD at 640x480 is near impossible without problems, I think this is your culprete

I think I've found something that might help lead me in the right direction. The video card has shared ram which increase if i play a video in a regular media player, but in reolume it never goes up. i can load it up with 3 clips and the video ram stays low.

I've tried a divx clip at 320x240 off of a thumb drive and it still didn't work.

Let me know if this video card thing could be the problem.

Peace,
CP

Try PicVideo MJPEG Codec... Its the best performance/quality you can ever get

PS: There's a link to it here: http://www.pegasusimaging.com/picvideomjpeg.htm

I'm pretty sure that the issue at hand is not the codec, but that the video card is not being communicated to properly by resolume. Thus the ram isn't being increased causing the video play back to be slow and jerky.

Any ideas from you leet programmers?

first of all , divx is not suited for vj-ing please try an mjpeg or indeo or cinepak codec. Second, playing video from a thumb drive is also not going to dive you the best performance. simply put all your video footage on the internal harddrive.

Looks like you were all right. Is the case that resolume doesn't interact with the video ram? I'm starting to think I went way over kill on my computer power.

I am sorry but it wont work with anything video. You need a computer with real graphic card. Not just Resolume, forget anything visual.

Uh...it works perfectly fine with mjpeg. The question is about how resolume interacts with the video card. Because from what I'm seeing having a high end video card makes no difference at all. Can some one clear this up?
