You mean level, not profile. Higher levels allow higher bitrates and more reference frames at high resolutions. See: http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC#Levels

You're right. crf 0 is unplayable on my Q8400.

Would you know where I could find out more about the --frame-packing option?

Many thanks.

In the command-line help (x264 --fullhelp), in the source code, and by asking here. What do you want to know?

rica · 19th December 2010, 01:46

mariner, give it a go with MeGui 0.3.5.0: just select x264 BluRay preset and select film, it's gonna give you this:

Code:

program --tune film --crf 20 --level 4.1 --bframes 3 --ref 4 --slices 4 --aud --nal-hrd vbr --b-pyramid strict --keyint 24 --min-keyint 2 --vbv-bufsize 30000 --vbv-maxrate 40000 --weightp 0 --colorprim "bt709" 
--transfer "bt709" --colormatrix "bt709" --output "output" "input"

What do you mean with frame packing?

If you mean real frame packing 1080+45+1080, you will need a MVC encoder.

Greetings rica. Thanks for the reply.

No need for --frame-packing 3 ?

The setting I used was

Code:

x264 --frame-packing 3 -o 700.mkv 3d700.avs

I would like to know what --frame-packing 3 does and what other numbers apart from 3 it can take.

Best regards

Me too.
What is "frame packing 3"?
I don't know what it is and what it's for?

rica · 19th December 2010, 02:53

Hold on.
I wanna share my trial results not now but tomorrow.
What i need now is just to go to sleep._00.4 AM here btw

Oh dear!

Let's wait for nm or sneaker_ger to give some guidance.

Blu-ray presets are not suitable for Mariner's work. He's encoding 3840x1080 video at 60 fps and very high bitrates, so overall that goes way over Blu-ray limits.

That's what this thread has been about since post #7. A bit off topic, yes, since this isn't MVC. Maybe a mod would like to split the discussion?

As I said, see x264 --fullhelp:

Code:

      --frame-packing <integer> For stereoscopic videos define frame arrangement
                                  - 0: checkerboard - pixels are alternatively from L and R
                                  - 1: column alternation - L and R are interlaced by column
                                  - 2: row alternation - L and R are interlaced by row
                                  - 3: side by side - L is on the left, R on the right
                                  - 4: top bottom - L is on top, R on bottom
                                  - 5: frame alternation - one view per frame

Many thanks, nm. Couldn't find anything typing x264 --help. My bad.

By the way, I encoded a 1920x2160 top/bottom using --frame-packing 3 by mistake. Seems to work fine though. Any reason?

rica · 19th December 2010, 15:23

Why 60 fps?

Here is what i get with MeGui preset:

Left-Right:

Top-Bottom:

I used Adam Stanislav's tool:

Maybe your decoder or player ignores the --frame-packing SEI and uses some frame size heuristics. Which decoder and player are you using?

Why not if that's what he has?

Btw, do you have some specific hardware player that supports side-by-side 3D with frame sizes above 1920x1080, or why are you using Blu-ray presets for the encodes? I don't think they'll be 3D Blu-ray compatible, afterall, or have you read the specs?

Using polarised dual-projector setup championed by BlackShark.

So how do you get the frames to right screens? Does that somehow happen automagically for both side-by-side and top-bottom videos when you play them in MPC?

I know none of them is BD compatible; some trials for archiving purposes.

I can watch them in 3D mode with -only TMT5 over my nVidia 430 and Acer 5360 PJ.

But i can get 1920*1080 3D files as well: (Both TMT 5 and PDVD 10 plays them flawlessly in 3D mode:

LEFT-RIGHT:

Code:

LoadPlugin("C:\DG\DGDecodeNV.dll")

lv = DGSource("C:\H264StereoSource_a2\left.dgi")

rv = DGSource("C:\H264StereoSource_a2\right_new.dgi")

LeftRight3DReduced(lv, rv)

ConvertToYV12()

or without DGNV Tools:

Code:

lv = FFVideoSource("C:\H264StereoSource_a2\left.m2ts")

rv = FFVideoSource("C:\H264StereoSource_a2\right_new.m2ts")

LeftRight3DReduced(lv, rv)

ConvertToYV12()

or:

Code:

lv = directshowsource("C:\H264StereoSource_a2\left.m2ts")

rv = directshowsource("C:\H264StereoSource_a2\right_new.m2ts")

LeftRight3DReduced(lv, rv)

ConvertToYV12()

TOP-BOTTOM:

Code:

LoadPlugin("C:\DG\DGDecodeNV.dll")

lv = DGSource("C:\H264StereoSource_a2\left.dgi")

rv = DGSource("C:\H264StereoSource_a2\right_new.dgi")

TopDown3DReduced(lv, rv)

ConvertToYV12()

Nice. So they support the SEI signaling or how do you specify which format is used?

It's actually quite crude and simple: create a 1920x2160 desktop using say ATI's Eyefinity software with two 1920x1080 projectors hooked up. Each projector will display the top or bottom half of the video.

I encoded them into mkv container and i have to select "left-right" or "top-bottom" on player's 3D Settings window before playing.

Yep, that's what I thought. So you'll need to manually switch the desktop layout if you have videos with different frame packing formats.
