Guide to convert BD 3D to 3D Left+Right Stereoscopic and Anaglyph

[crl2007]

I cannot stay and give you advices on how you should configure your drivers/decoders/filters. I wrote the guide, I specified the software needed, the settings for that software but this is it. I can give you more answers regarding the guide or things related, but not on your pc settings.

[Salehi]

tnx, so please give the official thread for x264, maybe they can answer.

[crl2007]

Search another x264 build and replace the one you have in your multiavchd folder.

This is the official x264 thread: http://forum.doom9.org/showthread.php?t=108570

Then use the switch BigPines told you about. --fps 23.976

[BigPines]

I can confirm the --fps switch absolutely works to encode film sources correctly. No need to change the frame rate later.

So now I am patiently waiting for my encode to finish. It is cranking along at a blistering .75 fps. At this rate it is projected to finish in approximately 76 hours. The placebo setting is serious stuff. Slow as molasses in January but the result is beautiful.

Ok guys, thanks.

The techniques we use (side-by-side (1 file, 3840x1080) and left-right (2 files, 1920x1080)) to create 3D encodes, are different from the ones used to create retail 3D Blu-Rays and appear to be unusable to create full-hd 3D Blu-Rays. Half-SBS Blu-Rays (even with selectable subtitles) are no problem, but I don't think that the Blu-Ray specifications allow 3840x1080.

Is there a way to create full-hd 3D Blu-Rays at home?

This is where I am headed next too. I currently use tsMuxer to create the BD file system and then burn that to a blank BD using Toast. I am looking for something that can create a true 3D BD disc in a similar way. Whatever we use will have to be able to accept two discrete video streams and create the right eye "difference" stream for the final disc. Anyone know of a solution?

This is why i'm interested in the first part of crl's guide.
Two difficulties here:

1) Re-encoding right-eye video. (i'm not satisfied yet.)
2) A free MVC encoder. (which is missing.)

The rest is no problem.

[BigPines]

rica,

I have verified the following works great for encoding the right eye: x264 --fps 23.976 --level 4.1 --crf 17 --preset placebo --tune film -I 24 --weightp 0 --b-pyramid none --sar 1:1 --aud --rc-lookahead 24 --output right_final.h264 right.avs

Have you tried something similar yet?

I used the 8 bit video x264.exe compiled for 32 bit operating systems. You could omit the --preset placebo switch and speed up your encode greatly. Also increasing --crf would decrease quality, file size and encode time while decreasing --crf would increase the quality, file size and encode time.

I think there are MVC encoder options but we need to figure out a complete solution. That is the next step for me.

UPDATE: A quick Google search revealed the following: http://www.mainconcept.com/products/...3dmvc-sdk.html

Not a free solution but interesting none the less.

BigPines, here is what i gave it a go: (8 bit 32 btw)

C:\H264StereoSource_a2>x264 --level 4.1 --crf 20 --tune film -I 24 --b-pyramid none --sar 1:1 --aud --rc-lookahead 24 -o right_son out.avs

Haven't tried --fps 23.976 option yet.

[BigPines]

I would definitely try the --fps switch. Since that other error is at the beginning of the encode, I suspect the source but I'm really not sure. Do you have another source to try for kicks?

Mike

[rica]

Yes i have but i need to have a break; get tired of trying lots of times.

Even i made it 23.976 later with TSMuxer here it is on Vegas; as you guess bottom is right-eye. (m2ts: re-encoded, re-set to 23.976)

[BigPines]

Based on your screenshot, it appears you got the entire right eye encoded so maybe the error happened at the end of the encode. If so, it could be normal. Obviously you have a problem with the length of the video due to the frame rate issue. The --fps switch should fix that. If not, I will likely be in trouble myself!

Mike

[rica]

Hold on. I will make just input and output.

[BigPines]

For those interested in free MVC encoders: http://forum.doom9.org/showthread.php?t=158457

Even if neither of these is usable in their current forms, a usable solution can't be far off.

I wonder if x264 will implement MVC? I assume they will eventually.

Mike

Mike, just started but it's clear he is making 25/1 fps again:

C:\H264StereoSource_a2>x264 --fps 23.976 --level 4.1 --sar 1:1 --aud -o right_new.264 out.avs

avs [info]: 1920x1080p 1:1 @ 25/1 fps (cfr)x264 [info]: using SAR=1/1

x264 [info]: profile High, level 4.1
[3.1%] 120/3927 frames, 3.22 fps, 435.75 kb/s, eta 0:19:43

[rica]

As expected:



3927-3867= 60 frames are missing.
