Resolume Forum

Hi all!

I just wanna play some short videos (2-5 sec) randomly without any effect or mixing on one layer, but the playback always slows down , like slowmotion

What the hell do I wrong or is that to much for resolume?

The videos are 640*480/32, indeo5.1, 100%, keyframe every frame. Config: 2.4Ghz P4, 1gb Ram, Radeon 9600 XT 128 mb Dualhead, brand new, clean xp pro. Playback: 640*480/32, fullscreen on secondary monitor, tv-out. Overlay mode is even worse.

Thank you in advance!

you should be able to do that easily...

What sort of size are the video files (per second)?

What video mode are you running your second monitor in?

Are you running anything else alongside resolume?

Do the clips play okay in media player?

Dan.

The videos are about 1,5mb/sec. The media player plays those videos without any problem whatever size I choose. I prefer the dualhead mode as the overlay mode doesn’t support bigger resolution than 320*240 as far as I recognized, but I might be wrong about that (am i?). The most disturbing is when resolume starts playing the videos backwards (bouncing) the vids hang after about a half second for a moment.

Nothing else is running, except for windows. This might be the problem

hallo s-boy!

you are "wrong", which means that there is a trick to pump up the res in overlay mode. i read about it in this forum as well and it works like that:
u undock the video output window and switch it to the resolution you want, using right-click and so on...
then rescale it manually by dragging the borders of the window. no matter how small you resize it, the output resolution should be the one u configured!
regarding the playback speed, i unfortuneatly cannot help you. my system specs are very similar to yours and i have the same problems. options are that you downsize your clips to e.g. 400x300. if you want to paly in fullPAL, maybe you shoul think about getting a RAID. i once read, that with the right RAID, you can playback full PAL clips without any problems...
is there anyone, who could affirm this?

anyway, hope i could help.

hi there,

i think the bottleneck is the HDspeed, try to compress the video to 90 or 85% to get smaller filesize without recignizable artifacts. it may lean a bit more on your processor but i think a 2,4 should have no real problems with it...
my gues is u are using a 7200 Rpm IDE HD? or external one? in other words... can u give the specs of your HD?

western digital make 10.000rpm harddrives with 8Mb cache (Raptor) in 36 or 72 GB - perfect for 3 layers of 640x480

hello!
would you recommend this harddrive?
or is it better to use a RAID system?

i kind of have the same problem and just posted a very similar topic titled CLIPSPEED. (should have read the other posts first - sorry). maybe you could check it out...

i am not even trying to playback full PAL clips! i would be satisfied with 400x300 resolution!
my harddrive isn't that bad either... (Western Digital Caviar 7200rpm, 8mb). i also have resolume installed on a different harddisk. and some clips are not much bigger than 400KB!

playbackspeeds are never quite the same. they change even while looping one video...

anyone having the same problem?

hi Mista,

aside from what i replied on the other thread its important to get a steady as possible datastream... so use keyframe every frame (also for stratching the video) and try using the "constrict datarate to:" button if u have it in your video-production program...
and calculate the bitrate of your clips multiply it by 3 and than check your hd's datarate and ide's datarate. if the datarate seems sufficient there may be something wrong with your motherboard or hd...

cool advices, superficial! thx a lot, i will try them out as soon as possible...
