Resolume Forum

I have Resolume Arena in a MacbookPro and when it is quite working for some time, the video begin to go very slow, until i quit Resolume and go back again. I was thinking that it happens when the laptop gets warm, but really quitting the software and coming back again fixes it. Why?

I wonder if this is related to the Quicktime RAM leak I keep hearing about?

Apparently the Quicktime X library isn't very efficient and leaks a bit of data which makes your RAM fill up; after a while it can make your computer become slower. The only way to stop it is to flush your RAM out by restarting the application.

Of course the bigger your RAM the less its effected.

I am not a programmer though so someone is bound to know a lot more about this than me. It might not even effect resolume - I am just wondering/pondering.

Quicktime is indeed a bitch when it comes to this, it doesn't properly close the files when they are not playing, so using lots of clips in a single deck can be problematic.

The good news is that this is not an issue when using DXV clips.

We've introduced a few improvements for non-DXV codecs in 4.1.4, but in general when you're not using DXV it's good practice to keep deck sizes relatively small (30-50 clips). When you switch decks, the RAM is properly cleared.

That's really interesting to know about the DXV file.... is this the same for the HAP codec by any chance?

The Hap implementation in Resolume is nearly identical to DXV. To be honest we didn't check the memory usage yet, and I currently don't have a beta with Hap support at my disposal :-/

I thought it might be.

Not a problem. I was just curious.

How to convert my videos to DXV codec?
