Image blurry

[Daniel28543278um3d]

I've been working on a short video for a class I'm in, but the images I upload come out blurry in the end. The photos themselves look good when just pulled up on my computer and when in my source tab. When I place the image in the timeline it zooms in, and when I go to correct that the image resolution is destroyed. I've also noticed when I place a transition from the pervious image to this one the image looks great but only while the transition in happening (see images below). Does anyone know how to fix this I've tried messing with the sharpen, unsharpen mask effects, changing the resoution and the picture types but to no avail? Any and all ideas are appreciated.

It looks like you have a vertical image, and zoom in to fill a horizontal screen?

What's the framesize of your sequence, as in 1920x1080 or whatever?

What's the pixel dimensions of the still image? As in 1200x1600 or whatever?

Thank you for your help. I'm not sure about the pixel dementions of the image they were taken on and Iphone 12 if that helps. I did however flip the frame size to 1080x1920 (as opposed to 1920x1080) and that fixed the issue for some images but messed up others that I;m guessing were horizontal images to begin with.

Is there a way to change the framxe size on certain sections of a video?

It looks like the preview render resolution may be low.

Try deleting the render files (Menu > Sequence > Delete Render Files)
that should turn the green bar above the sequence from green to yellow.
Does this give you better results?

Neil's comment solved my issue thank you for your input though!

Scale to Frame Size vs Fit to Frame Size in Premiere Pro

Importing images with "Scale to Frame Size" will resample your image.
This may degrade the image resolution. More on this subject can be read here:

Could this be causing your issue?
