Finally, I used ffmpeg to create an MP4 file, and I've included the
mediainfo description below.
(Why?)
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 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 \
This cannot be correct.
-y \
-coder 0 \
MH.mp4"
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).
Complete, uncut console output missing.
Sorry for not including that. I've included it below.
But when I play the ffmpeg file, it is
visibly jerky, and I'm not sure why.
Do you mean the quality of the encoded file is not ok?
Or is real-time decoding not possible?
Carl Eugen
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.
