Thank you for reply, any more ideas?

pdr is correct, this has nothing to do with 3D as it is. What media player(s) are you using? Nothing about the metadata suggests it's anamorphic either, but that 1st screenshot implies that it is.
Go back to square-one and fix your process.

i use latest version of Windows media player. Also tested in different pc's and same result. in windows media player

WMP has no understanding of 3D in the least. So where are you getting this "Media player detects video as if its 3d" business?
Scott -
Are you trying to be cute? The 2nd image is in a scaling box, that implies you rescaled the image......
What gives?Got my retirement plans all set. Looks like I only have to work another 5 years after I die........ -
i did not scaled the image i just tell you differences between 2 players. i am not good with video editing terms. In media player you see the video like in the first screenshot (tested with 3 different pc's). Thats what i call as "3d"
but in other players like mpc you see the video full screen. (Not squezed from left and right) -
Why on earth would you call that 3D?!! If I placed one stereo speaker (say "L") in front of you and the other speaker ("R") behind you, would you think you are hearing in surround? stereo3D is only stereo3D when there are 2 similar-but-not-identical images (where the difference is due to eye perspective). There are plenty of 2D images that are squeezed (anamorphic the most common) and plenty of 3D images that are NOT squeezed. There is only 1 image there, so it cannot be 3D and nothing but YOU is suggesting that it is.
If you have a problem with a certain clip playing properly (re: aspect ratio) in a certain player, explain it that way, upload a short section of the (otherwise unmodified) clip and clearly explain your steps, apps, version#s, etc.

if i upload the video in youtube it detects as if the video were 3d. as seen in the screenshots below:
http://prntscr.com/5lmip6 = Flash player
http://prntscr.com/5lmitc = html5 player
There is a hidden trick in the video which causes youtube detects it as 3d, thats what i'm trying to find out
Uploaded file: https://yadi.sk/i/aPVo-EjRdfHpE
Youtube link : https://www.youtube.com/watch?v=Ujs-9g_noss -
It is not a trick, it is how YT modifies the presentation to accommodate different 3D viewing scenarios. If you don't have 3D footage, you shouldn't use ANY of those scenarios and you shouldn't use the yt3d tagging.

i got it, if i render a video with Stereoscopic 3d mode. Youtube detects video as 3d. But in this example. There is no 3d mode but youtube detects the video as 3d.
the uploaded file is rendered version, if you upload the original file yt does not detects it as 3d. -
If you render a video with stereo3D mode, unless it is Dualstream or MVC (or MKV with 3D format metadata), YT cannot detect it as 3D because it is in actuality just a specially-adjusted 2D image. What gets YT viewers able to "view in 3D" does not have anything to do with the video itself (barring those 3 subtype exceptions), but with the yt3d tagging (which can be inserted at upload or after the fact, IIRC).
Your upload is MP4, so even if it WERE 3D. YT would still treat it as 2D until you added the yt3d tagging (because MP4 doesn't have any inherent 3d format metadata).
Scott -
i do not enter any yt3d tags i upload the file and yt detects it as if it were 3d. But i have downloaded the video from youtube using 4k vido downloader.
Maybe the original file was mkv or something else. when i tried to download it asked me if i want to download it as 3d or just 720p. i downloaded both.
720p version is the one which i uploaded. 3d version look like 640*180 -
is there any way to create a video which includes 2d and 3d in same file ?
-
MVC (or some forms of dual-stream). But that'll do no good if you are uploading to YT, since they re-encode everything.
