Alternative to interleave filter

I don't think it does explain anything. Yes, it looks smooth - because it's two self-contained videos side by side

Apologies for the following large and annoying animated GIF, but this may be the easiest way to make sure everyone is on the same page:



Rica, can you explain what, if anything, you find "wrong" with this image (and this image alone)? Is this the kind of "shakiness" you think is a problem?

So, the question is very clear: might there be any alternative of interleave filter, which is functional?

[wonkey_monkey]

Interleave functions perfectly! I don't think any of us understand what the problem you are having is - my own suspicion is that you have misunderstood something, and there is in fact no problem to be solved.

Sorry David, I've missed you post.
Yes that is exactly what I have been trying to explain.

Problem is still staying there. Can you tell me you can watch comfortably this garbage in 3D mode?

(And why don't you make an animation consisting of two frames taken from stack horizontal or original left and right frames? For instance frames 190 and 191? This will be a real animation of interleaving. If you make it and if we don't meet this belly dancing, I suppose you will understand me. - I mean 190-L+190-R +191-L +191-R.)

Then there is no problem. If encoded correctly, and viewed on a correctly set-up 3D display in interleave mode, your interleaved video will look exactly the same as your SBS video displayed on a 3D display in SBS mode.

This "shakiness" is an inherent factor of 3D video. I really don't know what you expect it to be like, other than this.

But if encoded correctly and viewed correctly there will be no shakiness because each eye will only see alternate frames. If you think you're viewing this on a 3D display, and you see this shakiness, you are doing something wrong.

My animated GIF is made from original left and right frames - frame 190 from each video, in fact.

Edited to add:

Are you trying to create what everyone else calls "interleaved 3D" but would in fact be better described as "interlaced 3D"?

left=ffmpegsource2("left.mkv")
right=ffmpegsource2("right.mkv")

David, I see what I see on VirtualDubMod playing to interleave.
I can not make an animation since there is no SW in my home PC to compare. Sorry but it doesn't seem they are the twins taken from the original L and R.

Sorry, but they are.

What is that?

Mine is:

lv=bla bla
rv=bla bla
interleave (lv,rv)

No, I don't think I am doing something wrong. I tried with avs and encoded video using SP in 3D mode. SP, set to frame-sequential (left image first) and nVidia selected as viewing method. I also gave it a go with PDVD 12. And please do not forget I can watch SBS very well with those programs in 3D mode.

I tried your interleave.mkv in Stereoscopic Player in anaglyph mode and it looked fine to me - although it did play back at half speed. Do you still get shakiness when you use anaglyph mode? Did you try encoding with --fps 50?

David

[rica]

Sneaker and David, thanks!

Finally I fixed the issue with encoding the video to 50 fps. I did not think interleave filter needs 2*fps while SBS and TB methods are OK with 1*fps.

Slow motion creates the shaking issue.

This looks great with SP in 3D mode while PDVD still shakes it since it does not have frame sequential option.

Thanks again.

C:\test>x264 --fps 50.00 --level 4.1 --sar 1:1 --frame-packing 5 -o final_03.mkvnewest_interleave_01.avs

And here is the resulting interleaved video:
