Samsung stretched video wrong aspect ratio

Postby Tesla99 » Mon Nov 15, 2021 10:40 am

I hope someone can help. I've got a Samsung 1920X1080 model HMX-H100N/XAA (Uses SD memory) It was purchased around 2010, took great videos. Now here is the problem, all my past videos are stretched on my two i7 computers running Windows 10. I got out the camcorder, it still works to my surprise, took a video and that is stretched also. Now the last time these videos were played and displayed correctly was on Windows 7, now all on Windows 10. I noticed this problem about a year ago and have ramped up my search for a solution over the past 3 months, I can't find anyone with this problem. Hoping someone on your forum can solve it. Looking at the file properties in Windows 10, it has 1920X1080, although it displays about 1920X600 in my estimate (horizontal bars top and bottom). Using Handbrake I can correct the video, but that takes a lot of time and may be reducing the resolution slightly but looks close to original. Handbrake thinks it is 3413X1080. What is causing this problem?

I don't know the answer, but I think it lies here:

Display aspect ratio : 3.161
Original display aspect ratio : 16:9
Clean aperture display aspect ratio : 3.161

My thoughts exactly, Peru. Though I'm not sure why Windows 7 would display the video differently than Windows 10.

What media player are you using to play the videos, Tesla?

Good hearing from you! I am using Windows Media Player but I have tried multiple players, they all stretch the video. If I upload to YouTube, YouTube also stretches the video. I have 100's of short videos of the family growing up I need to get unstretched. I just can't imagine what changed. Here is an old video from the camera unedited, interesting YouTube thinks it is in 4K, it's in 1080



How is "Clean aperture display aspect ratio : 3.161" calculated? If this meda data was changed to 16:9 (1.78) do you think the video would play normal?

Looks like when you created your source files you output in a 3.161 aspect ratio which is why you are seeing the letter boxing. Are you using any sort of video editor or simply just looking at source files. Are the files directly off your camcorder or did you do some editing then output to the file?

No editing, these are the source files off the camera.

Try using Handbrake on a small video clip tosee if you can correct the video dimensions. :)

Also, if you can share a clip of video from that camera via public Dropbox, we can try it on our machines and see if we get the same results.

But I think Sidd and the others have called it. You've got something set in the camcorder that's producing non-square pixels. Maybe a "cinema" setting.

I really appreciate your interest. Here is the original video (source file) taken 5/30/2011 HDV_1139. Hopefully I did the Google Drive link correctly. I have also reset the camera and it still stretches the video HDV_3439 taken 6/7/2021. This camera doesn't have "cinema". Looking at MediaInfo could the 10-year-old Codec be incompatible in someway? Those files had the correct aspect ratio back then, Codec ID : avc1 (avc1/isom)

Thanks for sharing the file, Tesla. And I can confirm that it's definitely set up to be a 3.161 aspect ratio and that that is why you're seeing it stretched wide. (I saw the same thing.)

For what it's worth, I ran the file through Handbrake and got a perfect 1920x1080 file that played as a 1:1 video.

If it's not an issue with your camcorder setting, it could be related to the way you're getting the video from the camcorder to your computer. How are you doing that? Are you merely moving the SD card to your computer and copying the file or are you using some type of software to make the transfer?

This is a discontinued camera so the specs available for it online are rather limited. But I don't see anything that would indicate that it has a cinema aspect ratio setting. So I'm not sure where this setting is coming from.

Thanks for analyzing the files Steve. In HandBrake what do you use for your quality setting, 19.5 produces about the same file size as the source and video looks good.
As for getting the video on my computer, I insert the SD card in the computer and use the window copy commands (Ctrl-C Ctrl-V)

I'm asking all my friends if they have a Windows 7 computer I can try my files on. Will let you know what I find out. All I know is these videos played correctly back in Windows 7 days.

Doing a little research I found this nugget: https://discussions.apple.com/thread/2167523

From the quick read I did looks like it might be an issue with Quicktime. Sounds like the solution might be to try and import the files to an editing program and that helps resolve the non-standard ratio. Not sure what editing program you might be using.

Thanks Sidd, from your link I found other sites that all complained about stretching on Mac's only with my model camera back in 2009-2010. I'm going to have to find a Windows 7 computer to satisfy my curiosity. I'm thinking Windows 10 copied Mac's Codec algorithm.
