Export Frame is creating images that are "stretched"

[Lukas25640623b8p2]

I am using the Export Frame option, in both the Source and Program windows. The frame exports just fine, but when I go to view it, the export process has stretched the contents of the frame to the point where it needs quite a bit of tweaking to get it to look right.

The exporting of video does not create any sort of stretching.

My pixel aspect ratio is set to "squre pixels." I have tried all matter of different sequence settings, and I can consistenly produce a very squished image by changing pixel aspect ration to any matter of settings, but I can never get it to produce a proper image.

Any ideas?!?!

Do your media properties and sequence settings match?

[Lukas25640623b8p2]

The media properties shows: Pixel Aspect Ratio: 0.8889

Everything else looks like it matches.

Iss that something I can change? Because it appears that its all from a drop down and there isn't a way to change the sequence settings to get the pixel aspect ratio to match.

You have to set the sequence PAR to 1.0 in order to get a correct image.

[Lukas25640623b8p2]

Does that mean re-encoding the footage at the 1.0 PAR or is that something I can do to the existing footage?

As mentioned, you need to make sure your sequence settings are as appropriate. The link below has good instructions with a video:

Key point in the settings - "Under Video, enter the Frame Size(height) and horizontal(width). Premiere Pro automatically generates the aspect ratio."

Thank you for that link, it has a lot of great information!

The video I export is fine, I haven't ever had a problem with distortion in a video clip. But when I export a frame from that same project with all the same setitngs, the image is stretched.

[Lukas25640623b8p2]

Here is some interesting information I just discovered.

When I look at Sequence Settings, the frame size is 704x480. No distortion in the video clip at all. Seems that everything is fine. However, looking at literally hundreds of clips I have exported using these same settings, the videp clips are actually 629x480. All of them. And they also look fine as far as I can tell. I have never noticed any stretching or distortion in the video clips.

Any idea what is going on here?

How are you viewing the frame exported?

Is it stretched if you import it and put it on the timeline?

[Lukas25640623b8p2]

When I view the frame in File Finder on a Mac, or when I open it in Photoshop to color correct it, it is stretched out.

Just now I did a new export frame, and checked the box to IMPORT INTO PROJECT and the frame is not distorted when viewing in the project.

[Ann Bens]

If your media does not have a PAR of 1.0 an exported frame of that video will always be distorted as it exports as 1.0 and not the PAR from the video. Still images can never have a PAR other than 1.0.

Ann ya te ha dado la respuesta un par de veces, debes ajustar tu secuencia con el Pixel Aspect Ratio en 1.0 (cuadrado) y ajustar los clips si es necesario. Si no lo haces, se seguirá deformando el Still porque se exporta como 1.0 mientras que tu secuencia está en 0.8889, ese es el issue.

[Michael Grenadier]

you can use photoshop to resize the still images so they'll display properly.    On the mac, I think you can use preview to do this...  not sure what the alternatives are on windows besides photoshop.  For example, if you have a NTSC DV quicktime, the pixel dimensions are 720x480.   You can resize the still image to display properly by changing the pixel dimensions to 640x480.

Todo esto tiene que ver con el Pixel Aspect Ratio, debes buscar información acerca de cómo funciona este asunto porque es normal que cause un poco de confusión.

[Lukas25640623b8p2]

Or in my case, a lot of confusion!

That is because your footage is non standard and takes a bit of background knowledge to get this working correctly.

Post screenshot of sequence settings and clip in MediaInfo in treeview here on forum.

This is great info, I have never seen this before! Thankfully the still images appear fine when I import them directly into the timeline, they are only distorted when viewing in PS or elsewhere.

That is normal behavior.

[Michael Grenadier]

but you can set up your image files in photoshop to display correctly.  this is a 720x480 file widescreen dv menu for a dvd.  you'd need to resize it to 854x480 for it to display properly on a computer screen, but you can set photoshop up in the view menu to display properly within photoshop.

Dont think its a good idea to change PAR if the original footage is 0.9.

In order to get a good still from a non-rectangular movie is to change the resolution, not the Par in the export. (e.g. 1024x720)

[Lukas25640623b8p2]

Do you mean changing the resolution of the image after I export it?

In the export settings.

Thank you for this, it is excellent information I was not at all familiar with!
