Thank you John!

Unfortuntaly, I cant change the object property to 1:1. There is no option for it. Screenshot attached, but it only shows 16:9 in the screenshot, other options are 2:1, 4:3, 5:4, 2.21. Nothing more.

@jeesa2

if it is not 1:1 set it to 1:1 - you may need to type this in the drop down box.

 I cant change the object property to 1:1. There is no option for it.

As John has said, type it in to the aspect ratio box. Click in the box, highlight the current ratio, type 1:1, then click OK. Your video will be reshaped to 1:1.

Brilliant, John. That solved it. Thank you!!👍💪

@johnebaker

John, too many question marks. There is a bug where the program doesn't interpret analogue AVIs as 4:3; this could be related.

@jeesa2

Could you host that file on a hosting site eg Google Drive and give us the link so we can have a play with it. I have already submitted a bug report on a similar issue and it would be good to have your file to demonstrate the bug exists on this file type as well.

@jeesa2

Jessa, don't worry about the file, I've made myself a 1:1 which shows the bug.

@AAProds

Hi Al

I created a square 1080 x 1080 HEVC export in MMS, the one you see in the video clip above, then imported that into a Social media square project, shows the bug.

Would you like that?

John EB

@johnebaker

Made one myself, John. I'll send it on to Magix.

Interesting that a 1:1 HEVC made in MMS then dragged back in shows the problem

But one made in Vegas then dragged into MMS doesn't have the problem.

@Gid

I made one with VDub and it has the problem. MMS and Vegas must come from the same stable. Oh wait... 😁

Here's my VDub file:

@Gid

Hi

Thanks for the heads up.

I have had a long shot theory and been looking odd AR videos, on and off for a while, that started with the AVI issue.

Compare the MediaInfo analysis.

1. From @jeesa2 video clip MediaInfo data:
   
   Display aspect ratio                     : 1.000
    
2. From my MMS created file
   
   Display aspect ratio                     : 1.000
    
3. From a Vegas created file there is no AR/Display aspect ratio data
    

I am of the view that the DAR in 1 & 2, being expressed as a single number instead of a ratio ie 1:1, MMS/VPX are mishandling this single value and using it to select 16:9 as this is the only option that starts with a 1.

The Vegas produced file having no DAR data forces MEP/VPX to use the actual dimensions to determine the AR

John EB

@johnebaker ? I looked at MediaInfo while i was testing the two

This is the MediaInfo of the Vegas one I tested above,

& I created a new Vegas one just to check

@Gid

Hi Gid

Thanks for the info.

I, too, went back and retested with new versions and the DAR is in the Metadata - I am now curious as to why

1. the first one I made had no DAR line/value present
    
2. Why does this one import correctly !

John EB

@johnebaker I did the Vegas one again at 30fps instead of 29.97fps just so they ae the same, no prob opening it in MMS. Apart from bit rate & file size I can't see any significant difference between the two 🤷‍♂️

@johnebaker @Gid

I think it's HEVC-related. A square H264 file from VDub displays correctly. And the HEVC file opens stretched in MEP 2021, so the bug has been around for a while.

@AAProds Def HEVC related, I tried a few AVC's, they had no problem.

@johnebaker @AAProds This is the HEVC exported from MMS & dragged into a 1:1 project in Vegas. if I change the AR to 1.000 it displays correctly.

It displays correctly in Resolve & Boris's Silhouette & Mocha Pro 🤷‍♂️
