[FFmpeg-user] 3D SBS with ffmpeg quality question

Discussion:

I am trying to come up with a reliable method to burn my 3D BluRays to
disk as SBS MP4 files that can be played with plex on my 3D projector
with tools on linux. Specifically:

   makemkv 1.12.2
   ffmpeg 3.4.2

I have succeeded in making a SBS MP4, and it DOES work, but I'm not yet
satisfied.

I'm experimenting with Monster House 3D in case that matters for some
reason.

My first experiment was to use PavTube Video Converter (on Windows) to
create a 3D SBS MP4 file since that has worked for me in the past. I
used the default settings:

   Video
     Codec: h264
     Size: original
     Bitrate: medium
     Frame Rate: original

   Audio:
      Codec: aac
      Sample Rate: 48000
      Bitrate: 96000
      Channels: Stero

   3D
      SBS (half-width)
      Depth: 60

I was able to view it with my projector, and it worked well, so that's
the base quality I'm shooting for (though I'd be fine if I did even
better of course).

I ran mediainfo on it so I knew exactly what parameters I was trying to
reproduce, and that output is included below.

So next, I try to reproduce that with a combination of MakeMKV and ffmpeg.

I used MakeMKV and created a .mkv and ran mediainfo on it. I've
included the output for the video portion below (since audio is
satisfactory, I won't include that info here unless requested).

Finally, I used ffmpeg to create an MP4 file, and I've included the
mediainfo description below. I used the command:

   ffmpeg \
      -i Monster_House_t00.mkv \
      -filter_complex stereo3d=al:sbsl \
      -vcodec libx264 \
      -acodec aac \
      -s 1920x1080 -aspect 16:9 \
      -b:v 15000k \
      -b:a 448000 \
      -ar 48000 \
      -r 23.976 \
      -y \
      -coder 0 \
      MH.mp4"

I thought I had all of the parameters set that I needed, and based on
the output below, the two MP4 files seem virtually identical.

The size of the two MP4 files are quite close.

But when I view the PavTube MP4 file using vlc, I see the SBS images,
and they play quite smooth. But when I play the ffmpeg file, it is
visibly jerky, and I'm not sure why.

In case it's useful information, if I view the mkv file with vlc, it
plays smoothly (though I don't see the SBS of course).

Any suggestions for what I'm missing?

Do you mean the quality of the encoded file is not ok?
Or is real-time decoding not possible?

Because I thought it would help :-)

I'm new at using ffmpeg. Up to now, I've just been using windows tools
that I bought (like PavTube) which have basically been point and click
and I've been learning as I go what all of the ffmpeg options mean. I
used mediainfo to help me along because it told me the parameters that I
thought I would want to duplicate. I apologize if that was too much/too
useless information. Basically, at each step, I was trying to get all
of the video parameters in the ffmpeg version to match those in the
PavTube one at which point my assumption was that the video would be of
comparable quality.

Apparently that's not necessarily the case, and I'm failing to
understand something and hopefully this exchange will help me there.

I'm not sure why you say that this cannot be correct. I promise that
the above command is EXACTLY what I typed. As a matter of fact, I just
copied it from my message and ran it again (the only change being that
I'm writing MH2.mp4 so I don't overwrite the previous one). It hasn't
completed... but it is running right now.

It appears that you're targeting the '-r 23.976' option, but until I
included that, the frame rate of the file produced was wrong (I don't
remember what it was... but it was less than 23.976).

Sorry for not including that. I've included it below.

I do mean that the quality of the encoded file (ffmpeg) is inferior to
the PavTube version.

It's a bit hard to describe (and I'm not certain anyone wants me to
attach a portion of the video). When I watch the PavTube version, the
animated motion is smooth. When I watch the ffmpeg version, it is not
smooth. It's almost like a claymation animation where a few frames of
quick motion and then a few frames of less motion, rather than the
motion spread out evenly among all the frames, so the motion is jumpy
instead of smooth.

The sound that goes along with it is fine (no audible skipping or jumping).

Hopefully that clarifies what I'm meaning.

If there's any other information I need to provide, let me know.

Hi Sully,

Post by Sully Beck
I am trying to come up with a reliable method to burn my 3D BluRays
to disk as

Are you burning, as in "creating an optical disc", or are you ripping,
as in "writing the BluRay disk's content to a file on harddisk"?

Post by Sully Beck
I'm not sure why you say that this cannot be correct. I promise that
the above command is EXACTLY what I typed.

Yes, but it is not exactly what the frame rate is. Have you even
compared the output of your mediainfo commands?

-Frame rate : 23.976 (24000/1001) FPS
+Frame rate : 23.976 (23976/1000) FPS

The latter is from ffmpeg. You should have told ffmpeg to use
"24000/1001", to be precise. It may or may not matter for your player
though.

Post by Sully Beck
I do mean that the quality of the encoded file (ffmpeg) is inferior to
the PavTube version.

Did you notice that you did "imitate" some of the details of the
PavTube encoding, but not all? If, again, you compared your outputs,
you would have noticed differences such as:

Format/Info                              : Advanced Video Codec
-Format profile                           : ***@L4.1
+Format profile                           : ***@L4.1
Format settings, CABAC                   : No
-Format settings, ReFrames                : 1 frame
+Format settings, ReFrames                : 4 frames
Codec ID                                 : avc1

and especially:

-Writing library                          : x264 core 148
-Encoding settings                        : cabac=0 / ref=1 /

+qcomp=0.60 / qpmin=0 / qpmax=69 / qpstep=4 / ip_ratio=1.40 / aq=1:1.00

Since PavTube uses libx264, you may have a chance of duplicating its
results if you use those exact setting for x264. I don't know if you
can hit them with an ffmpeg combination of "-preset" and bandwidth (and
"-crf") options, or you have to duplicate them through the "x264opts"
and "x264-params" options. But that's worth a try, unless someone
figures out from looking at this why it yields worde results.

I'm confused that ffmpeg's options seem to be trying harder to get a
good quality/bandwidth ratio, but don't succeed according to your
observation. But I'm no expert.

Good luck,
Moritz

Ripping. Ultimately, I want to write the contents of my 3D BluRays to
3D SBS MP4 files on harddisk.

I apologize for using the wrong word. I'm actually still early enough
in the learning process, I know that I don't always use the correct terms.

I'm not sure why you say that this cannot be correct. I promise that
the above command is EXACTLY what I typed.

Yes, but it is not exactly what the frame rate is. Have you even
compared the output of your mediainfo commands?
-Frame rate : 23.976 (24000/1001) FPS
+Frame rate : 23.976 (23976/1000) FPS

I had compared those two lines. I could see that the ratio was
different, but I had assumed that they were 'close enough'. Probably
another bad assumption on my part. I'm sure I've made several of those
in this process. I will try again, again.

The latter is from ffmpeg. You should have told ffmpeg to use
"24000/1001", to be precise. It may or may not matter for your player
though.

I do mean that the quality of the encoded file (ffmpeg) is inferior to
the PavTube version.

Did you notice that you did "imitate" some of the details of the
PavTube encoding, but not all? If, again, you compared your outputs,
Format/Info                              : Advanced Video Codec
Format settings, CABAC                   : No
-Format settings, ReFrames                : 1 frame
+Format settings, ReFrames                : 4 frames
Codec ID                                 : avc1

Like the framerate difference above, I saw those differences, but I
wasn't sure that they would matter. I probably need to just work to
reproduce all of them. I'll spend a bit more time and report back in a
day or two.

Since PavTube uses libx264, you may have a chance of duplicating its
results if you use those exact setting for x264. I don't know if you
can hit them with an ffmpeg combination of "-preset" and bandwidth (and
"-crf") options, or you have to duplicate them through the "x264opts"
and "x264-params" options. But that's worth a try, unless someone
figures out from looking at this why it yields worde results.
I'm confused that ffmpeg's options seem to be trying harder to get a
good quality/bandwidth ratio, but don't succeed according to your
observation. But I'm no expert.
Good luck,
Moritz

Thanks for your reply. I'll reply again once I've gotten closer.

PS: They even sell on Amazon;-(

Pavtube (aka i-loveshare and multipelife), among the dozens of similar re-branded clones, is Chinese software commonly spammed on countless forums, reddit, Stack Exchange, mailing lists, etc, by shills recommending it.

It is basically a GUI for ffmpeg and other open source software, but no efforts are made to comply with any licenses. They distribute ffmpeg with non-free components enabled.
