why image size discrepancy between photoshop and premiere ?
Hello Creative Cow.
I would be very grateful if someone could explain the reason why a 720 x 576 image made in photoshop does not fully fill an SD video frame in premiere. Even when the ‘default scale to frame size’ is checked the still image is still too narrow by around 18 pixels.So i make all the images slightly wider, no problem. I just would like to know why.
Thanks for reading.

This is because the pixels in SD video aren’t square, while the pixels in your image from photoshop are.
Three ways to handle this:
1) As you noted, add more to the sides of the image.
2) When you create the image in photoshop you can set it to non-square pixels. If you hit File > New… there is a twirl down arrow marked “advanced” where you can select the pixel aspect ratio. (select the “D1/ DV PAL (1.09)” option in your particular case) Then you can paste your image content into this new file.
3) Adjust the pixel aspect ratio of the existing image in premiere. Right Click on the file in the project panel and select Modify > Interpret Footage… Under “Pixel aspect ratio” select “conform to…” and change it to D1/ DV PAL.

…agreed.
Being able to just right-click and adjust pixel aspect ratio and frame rate on a clip with absolutely no rendering or asset duplication is extremely convenient.
