I'm trying to use SVP on a FullSBS video (3840x1080) that I output to a 3840x2160 display mode and looks like this in PotPlayer (using 'Stretch'):

But when I enable SVP RIFE the aspect ratio gets wrongly changed to this:

Despite having 'Crop video frame' and 'Alter video frame size' disabled:

How can I make SVP stop altering the aspect ratio?

I am Bombadil at AVSforum, the author of those posts. Still using the same NexiGo Aurora Pro 3D projector, but switched from DmitriRender to SVP RIFE, and I am using Frame Packing 3D mode now that SuperDepth3D supports that mode since a few weeks ago.

My projector only supports Full 3D in Frame Packing and Frame Sequential modes, while SBS and TaB/OU are Half resolution.

What I do to be able to use Full 3D is create a Custom Resolution in Nvidia Control Panel with these settings:

So Windows gets a resolution with a proper 16:9 aspect ratio, while the Active Pixels output to the projector is the correct 1920x2205 for Frame Packing (vertically stacked 1920x1080 per eye + 45 pixels blank in-between)

I'm on the same boat here.

3D MKV rips work fine. Just watched a 1920x2160 rip of 'The Avengers' yesterday  and it worked great with SVP RIFE in Frame Packing mode, just adding a little zoom to compensate for the 45 pixel blank space that made a bad effect on the top and bottom edges.

The file has these video settings:

But SVP doesn't work with .iso files or untouched rips (MakeMKV) from them.

Without VapourSynth, .iso files play ok:

but once VapourSynth is enabled only one eye is displayed:

I tried installing other versions of VapourSynth but they either do the same or don't even start playing.

So my solution so far is using MPC-BE with DmitriRender in Full OU format with Frame Packing mode on the projector.
I normally use PotPlayer for everything, but this combo only works at Half Resolution in PotPlayer, and crashes when using Full Resolution:

I would love to use SVP RIFE instead, but sacrificing half the resolution is just too much. I'm already forced to downscale to 1440p to be able to maintain stable 60fps with SVP RIFE, while DmitriRender works at full 2160p resolution without problem (because no AI).

Maybe

can shed some light on this VapourSynth issue?

LosslessScaling is the best $10 spent ever.

Maybe, I tried so much stuff I don't remember.
It works now without crashes, but maybe the installation should give some error or whatever?

The log/details say "Press any key to continue..." but it seems the user can't do that.

the installer stayed at that 97% and not even trying to Cancel worked. I had to kill the whole SVP-maintenance in the task manager.

Same with a lot of other online videos, like this:

Tried Uninstalling and reinstalling from scratch but it's the same, keep crashing.

I think DmitriRender shows less artifacts here than any other solution I tried so far, but it has its own general problems, like artifact halos around people, which gets annoying and SVP RIFE is better at that.

Hardware MEMC is pretty good nowadays, but when there is high motion it just stops processing to avoid 'making a mess'. That prevents it from showing artifacts, but for me that smoothness unstability is more annoying than fluid motion with some artifacts.

You talking about using *just* LSFG? with no SVP RIFE at all?

Just tried with LSFG 3.0 x2 and x4, and certainly there are artifacts.

With SVP RIFE too, and also DmitriRender and hardware MEMC.
No solution is perfect in these areas:

In my movie tests 4.22 Lite is the smoother one with less artifacts. 4.25 and 4.26 may have less artifacts sometimes, but are not as smooth.

Does SVP RIFE TensorRT use Optical Flow or is it only for the other modes?

vs-mlrt has been updated to 15.8 at https://github.com/AmusementClub/vs-mlrt/releases/

Besides support for RTX 50-series, are there any improvements we can expect on current GPUs by using this new file?
