My video keeps exporting blurry

[sofiaarias]

I've exported like 8 times in different settings and I don't know why it keeps exporting blurry. It's not blurry in the preview (match source: high bitrate is blurry on the preview) but it's blurry after exporting. I've tried match source: high bitrate, vimeo 460 SD, youtube 1080 HD, custom, and probably more that I don't remember. I've exported projects before and this has never happened to me so I have no idea what to do. Here's a screenshot of my settings:

Your source video is only 275x183 and nowhere near 1080p.... with upscaling yes it would be blurry....

You are trying to make a poststamp into a poster.

Post screenshot properties of main clip.

275x183 is really very very very small.

I'm new to Premiere still I don't know why it was that small. I changed the size in sequence settings and exported again and it worked. Thank you!
