Resolume Forum

Hi guys

I am struggling to smoothly playback movies of 11500 x 2800px. No complex mapping, only using one layer, just splitting the movie to three 4K outputs...
The machine I am running it from has enough power to process this easily (SSD: Samsung 960 PRO, CPU: Intel Core i9-7980XE, Graphics 2x Nvidia Quadro P6000 with 24GB of VRAM per card, RAM 128GB).

I use DXV at medium quality and going back to 30fps but still I don't get a perfectly smooth playback.

My question now is; lets say the movies are coming out of After Effects or Cinema4D. What would be the ideal process to convert it to DXV. Should I first export a PNG image sequence and then convert it to DXV, or to a quicktime container with H.264 codec first and then do DXV...? What is the ideal process to make this DXV?
Looking at the file sizes of DXV I guess its uncompressed, so should I export the movie out of After Effects as uncompressed picture sequence (TIF) as an example..?

Really struggling here...Thanks for your feedbacks...BR

In the end, it really doesn't matter. I would go for highest quality throughout the whole workflow if you have disk space to spare.

I remember reading somewhere an article that 16bit PNG was the best quality and disk space ratio of all the render options. But don't quote me on that; has been for years! But I personally do render out on PNG. Personal preference and force of habit.

Maybe this will help you out further.

Is this within Resolume?
How fast are you visuals going?
Are you using motion blur or not?

Many factors are at play here.

Why 11500x2800 when you splitting in three 4K outputs?

Straight conversion to DXV with After Effects using either the Render Queue settings of the Adobe Media Encoder Queue (that's what I use). All you have to do is create a default preset.

I made a 11500x2800 DXV high quality alpha file (using the Resolume Orange String stock clip) for you to test and I'm including the original media clip to compare. On my 2017 MBP, it seems to be running fine.

Thanks for your reply! I converted the movie into DXV in Adobe Encoder. My movies normally come with 60fps, but I reduced it to 30 fps and to "medium quality" and "no alpha" in the DXV settings.
And yes, inside Resolume at 100% speed and no motion blur...

Many factors are at play here.

Yes you are right, but I am just looking for the ideal process to generate movies for Resolume which run at maximum efficiency...

It is about bringing these pixels onto 12 screens in a video wall. Thats why I split the input into 3 outputs, like this 3 times a third of the movie goes to a Datapath, and from there to 4 screens per Datapath. See flowchart here: https://we.tl/GyUffFeHVI

Thank you! I'll give it a try and give a feedback asap...

I just didn't understand why you had 2800 pixels high, but in your PDF, I see that the texture is 11655x2187 which makes sense with the bezels.

I played the sample file having the composition settings at 30fps. It played at 27.5-30fps.

Then I saw that your file has 23.98 fps, so I changed the composition settings to 23.98 too. It then run between 22.5 and 23.98. Again it didn't run at 23.98 constantly, which is quite disappointing...

Right, I actually wanted to write 2180 as I didn't had the exact number in my head and than made a slight fault

Whatever, looks like my issue goes deeper than expected. Probably I need to make sure the graphic cards are used in a way that Resolume can take as much advantage of it as possible... With/without SLI bridge, all 3 outputs connected to one graphic card or split it up..? And so on...

You should be able to run your installation off of one P6000 card (no SLI) and 3 Datapath FX4 Displayport no problems.

I have this impression too... should...
