Topic: PLEASE HELP: SVP4pro not working bd3d.iso (framepacking) + MPC-BE1.8.8

PLEASE HELP.

I'm guessing this is the best place to ask, as I just cannot seem to find the answer anywhere else:
How can I get SVP 4 Pro, to work while watching a BD3D.iso file (frame-packed 1080p@24hz) using MPC-BE x64 ver: 1.8.8?

I have a gaming projector (viewsonic px749-4k) which does frame packing at 1080p23.98hz or 24hz, and I can get frame packing to work automatically by doing the following:

1. Get blueray 3d iso file on harddrive > rightclick >mount. (this takes a minute or 2 and once mounted is see the iso file as a dvd drive: F with its name)

2. I ensure Stereo 3d mode is in Auto, ie. I go to menu > view > stereo3d mode> ensuring its at 'auto'.

3. I open MPC-BE x64, and goto file > open disc > and click on my BD3D file:

Although my pc's display is set to 1080p at 120hz/fps (actually it doesnt matter what its set to initially), the projector's auto Frame packing kicks in, where the screen suddenly goes dark, changing from black, grey, green blue shades very quickly, and the resolution changes automatically to 1080p24hz, and the movie starts playing in 3d... works perfectly. The video renderer, internal and external filter settings are as follows:

As you can see, no external settings.


But when I open SVP 4 Pro, i get 'no active playback' while the movie is playing.


I've gone through the first thread of this post, I've followed the directions in the following link: https://www.svp-team.com/wiki/SVP:MPC-BE
but when i put in any external filter, eg. Avisynth Filter as suggested via the above link, or ffdshow raw video filter as suggested in the first post,
YES SVP 4 works, says there is active playback, however, auto framepacking no longer kicks in when I start the movie..... instead, i get the 2 images, upper and lower.

Same thing, framepacking doesnt work, if I get rid of madVR as renderer. So it seems, I need MadVR as renderer to get my projector to automatically get framepacking 1080p24hz to work, but once i add an external filter (like Avisynth which allows SVP to work), the 3d framepacking no longer works. Its one or the other, not both. Please if anyone knows how to get both working, that'd be a dream come true.

dunno, the modern 4k projector must support frame packing input
for the frame sequential you probably need PotPlayer instead (but check the manual, only older PotPlayer versions are working)

I appreciate your feedback and getting back to me.
My projector does support frame packing input (see at the bottom of projector's spec sheet), hence I get 3d framepacking to automatically start and work perfectly as soon as i play a bd3d.iso via MPC-BE with Madvr (only seems to work with MadVR as video renderer). Automatically plays 3d framepacking at 1080p@24hz and looks great... but I wished it was smoother, ie. wished i was able to incorporate some for of interpolation/smoothness. I just can't get SVP 4 pro to work at the same time, even though people report that it's supposed to be able to work with MPC-BE ... and supposedly 3d framepacking.

"i get the 2 images, upper and lower" -- this is "frame packing"

but the frame packing is at 60 fps, while your table list only 1080p at 24 fps

what if SVP is active, but turn off frame rate conversion in a video profile?

Re: PLEASE HELP: SVP4pro not working bd3d.iso (framepacking) + MPC-BE1.8.8

3D frame packed: 720p 60/50, 1080p 24
3D sequential: all the above including 1080p@60fps

Re: PLEASE HELP: SVP4pro not working bd3d.iso (framepacking) + MPC-BE1.8.8

as I said - if your projector only wants frame sequential for 2*1080*60, then try PotPlayer

I don't have any frame sequential device, my LG 4K works perfectly with 4K@60 frame packing

My projector automatically goes into frame packing mode when playing a bd3d.iso in mpc-be... works perfectly, just the SVP doesnt work, showing no playback when i open it.
My projector can do both. Frame packing is automatically picked up, when playing the correct 3d.iso. Frame sequential is something i actually have to turn on, and is only used with a sbs or o and u mp4 video.
