Scripting is your friend.

I do not know scripting 😞

If the original is correctly flagged, Vegas will do this for you, no hassle. But we dont know that yet.

I assume anamorphic footage got shot by using anamorphic lenses so probably there would be no such a flag.

Aboammar, if we know which kind of footage this is and which anamorphic ratio the lense is, it should be easy to find a way writing such a script.

He already seems adept at handling Cine production formats on his website examples, so I wonder just what he is asking?

I assume that Cine formats (e.g., 2.39:1 Scope) would have encoding PAR correctly flagged, and thus would open quite handily in Vegas.

You would think those multitude of ratios would already be incorporated in the Vegas menus. It seems to me a very easy addition, what the heck, they added everything else except the kitchen sink.

Hi Guys,

@Musicvid  I am not sure what you mean by correctly flagged! Could you please elaborate?

@Marco. The footage are FullHD shot with Sony A7S M2 using SLR Magic MicroPrime Cine 35mm with SLR Magic Anamorphot-65 1.33x Anamorphic Adapter. The anamorphic ratio is 1.33

@JJKizak I totally agree with. Magix should add this feature.

Post your file properties and an original sample upload to Drive or Dropbox and I will do my best to help you.

I feel like I am repeating myself.

If you use an anamorphotic adapter there is no chance to let the camera write an appropriate flag and no way for an auto-adaption in Vegas Pro.

You need to set the pixel aspect ratio to 1,33 in the clip properties. Also you could set your project size to 2560x1080 (or 1920x808) for HD video or to 5464x2304 (or 4096x1728) for 4k video if you'd need an output adapted preview.

Now let me see if there is a free single script to do the pixel aspect correction for all selected clips in one go.

Here is the script.

Download, unzip and move the file PAR.js into the Vegas Pro script folder. Then select all clips in the timeline and run the script via the Tools menu.

This is an anamorphic 2.35:1 version (1.33 adapted to 16:9 right the way your Magic Anamorphot does):

And this is adapted in Vegas Pro the way described above:

@Marco. Thank you very much for taking the time to write the script for me .. I highly appreciate it 😉

However, I am facing a strange problem! After applying the de-squeeze, the image does not look right to my eyes and I can tell that it is squeezed vertically! Any idea what is going on?

@Marco.  I did a quick test and shot a perfectly circular objects:

Now it looks very clear that the image is indeed squeezed vertically!

I zoomed in and applied a red circle over one of the objects and you can see how much the image is squeezed:

I also increased the vertical frame from 808 px to 880 px and now the image looks normal:

Any idea what is going on?

Any chance to share a frame of your original footage?

@Marco. Here is a link for the original test footage:

Thanks for that clip.

It's strange, because that means the anamorphic ratio isn't 1.33:1 but less (looks like actually it is 1.22:1).

Here is my screen grab based on a 1.22 correction:

@aboammar
This MP4 file you offered above - is this the straight camera recording or was it pre-edited somewhere else. The squeeze ratio is really special.

Edit:
After several tweaks the closest I can get is using a PAR of 1.22727 – but that recording definitely is not 1.33 (or 2.35 as final result).

@Marco. It's indeed strange! I bought the SLR Magic anamorphic adapter from B&H and according to B&H and SLR Magic website, the anamorphic ratio is 1.33. Check for yourself:

http://www.slrmagic.info/product/Anamorphot+Adapter+65133X

The MP4 file I shared with you is straight from my Sony A7S II with SLR Magic MicroPrime Cine 35mm lens, and the SLR Magic Anamorphot-65 1.33x Anamorphic Adapter is attached to the lens.

So what could be the problem? Is the adapter defective, for example?

Here's a Stream Information grab using FFmpeg that shows it's reported to be a standard HD file--nothing unusual.

My suspicion is that your camera doesn't "know" the types of lenses and adapters that have been added and hence adds its usual metadata. I suspect that you will need to manually set the correct file properties inside of Vegas.

@wwaag
That's what the script I linked above does. It sets the pixel aspect ratio to 1.33 and this is the way all NLE correct anamorphotic 1.33 HD shots. It's a common workflow to achiev 2.35 display aspect ratio from 16:9 recording having used 1.33 anamorphic lense adapters.

@aboammar
Yes, I already checked that adapter and I could not find any unusual information about it. It's a common 1.33 lense adapter to be used for MFT and full sensor 16:9 HD and 4k recording.

If the lense adapter is new enough maybe it's worth shooting a series of test recordings with different types of circles and squares centered in the image to surely proof it isn't squeezing correctly. Then eventuelly sending the lense back and ask for a replacement.
Or - if possible - borrow a second one and compare both adapters.

Or take it as it is and try to find the best correction ratio (the 1.22727 I found should be very close). The very disadvantage of this then is, you would either need to accept small black bars in your final output or you would need to use an unusual render size.

@Marco.  I sent email to to SLR Magic about the problem and I got this reply:
"The anamorphic ration is 1.33:1 at infinity setting. As this is an Anamorphic lens, shooting closer than infinity will have anamorphic mumps characteristics."

I am not sure I understand the reply! What about you?

Oops, if I understand correctly this would mean the squeeze factor would vary with the objects distance. Sounds strange to me but I lack the experience. I will ask our camera staff soon.

I believe they are speaking of close-ups verses infinity focusing which will cause some linear distortions. However I fail to see how this would affect the aspect ratio at all unless you are double focusing through an adapter anamorphic lens which then you might see vignetting.

I think this combination of lense and adapter forces double focusing.

@Marco. This is also what I understood, but I was not sure and thought I might be wrong!
