Using Resolume to display show/mix longer videos

[markfrancombe]

I have a job coming up to project over a Theatre perfomance.
I KNOW what the recommended size length of videos should be (well not off hand, but I know there are some), but Im going to be getting about 8 x 5 to 10 minute videos to display. 1 per section of the piece.

I was wondering if resolume woul be able to handle, these longer form videos. I think its an ideal tool cos I can fade from one video to the next, add titles, and other effects on other layers... but Im worried that these videos would be "too heavy" ad the computer would seize up and crash...

I cold at a pinch re size them to a Reso-friendly resolution, be a bore to have to do, but ok... but what of length.. 5 or 10 minutes?

Have you done any tests? - I'd recommend this first.

you mention 8x5? what is this related to, the aspect ratio? What is the resolution of the clips?

The max resolution will depend on your graphics card but Resolume can have comps 8000x8000 (its a little more than that but I'm unsure of the same figure)

the length shouldn't be an issue. Will you be using Audio too?

I think he meant 8 videos 5-10 minutes in length, right?

Shouldn't be an issue as long as they're encoded with DXV. I have to convert client content all the time, even DJs that show up with their own visuals (some 20-30 minutes long).

I've even converted all of the DVJ Vision DVDs over to DXV (full length, about 45 minutes each) and they playback just fine.

Everything I run is 1280x720 and it's off my MacbookPro. The only issues I've ever run into is having problems with bass vibrations slowing the playback to a crawl (which shouldn't be an issue for you in a theatre setting)

Wow, thanks for the responses guys Yes I meant I have to play 8 videos...

I did some tests I actually after a longish load.. they works fine.. very happy.
That was a nothing special codec by the way H264..
thanks for the tip about DXV, Ive never used that codec, but Ill give it a whirl, as you say I SHOULD probably bother to encode them all myself to something friendly- I just not too sure when I will receive them. So was getting a bit worried.. you have put my mind at rest...

h264 will always load slow, it's probably one of the worst codec's to use for VJing.

hahaha i have no idea why i couldnt read that properly. glad your sorted though

Hey guys,


talking about very long videos: I have a gig on saturday for which I need to load multiple sequences of more than 15 mins. When they are played, if I clear the clip, can I be sure that it is unloaded from my memory (RAM) ?
What happend when I selected another video clips deck ? Are the clips unloaded from memory or still present ? (I guess so since you can quickly switch between decks).

Thanks

When they are played, if I clear the clip, can I be sure that it is unloaded from my memory (RAM) ?

No. Using DXV will let you free up more memory this way than other codecs, but all files will eat up some RAM as long as they are loaded in a deck.

What happend when I selected another video clips deck ?

That's the only way to be sure all the clips from the previous deck are unloaded.

Btw, length of the video file makes no difference for the amount of memory it uses. Only resolution and codec matter.

Thanks Joris, but I don't understand your last sentence: does this mean that if my clip is 10 mins long or juste 1 second, it will take the same memory ? (but not the same hard drive space)

[Joris]

Yes, that's what I meant to say, sorry if it wasn't clear.

We do not load the entire file in memory, that's madness with modern resolutions. We just open it, like you would open it in Quicktime Player, so it will play without any delay upon triggering.
