Sequence size does not match footage. Drop a clip on the new item button or right click clip and choose new sequence from clip to get the right settings.
Hey so there's likely one of two things happening here. #1, it's like some one else said here, your sequence resolution is smaller than you footage resolution so it's being cropped. Simply change your sequence settings by going to Sequence > Sequence Settings... and change it to match the resolution of your footage. Or you can scale down your footage to match the sequence resolution. You can either right click on the footage and select "Set to Frame Size" or "Scale to Frame Size". Those options are very different so be careful. "Set to Frame Size" prevents loss of resolution because it (ironically) scales down the footage. You can verify by selecting the clip, navigating to the Effects Controls, and seeing if the Scale under the Transform tab has changed. "Scale to Frame Size" will simply fit your footage to the size of the sequence but it won't change the scale. In other words, you lose those pixels. Sometimes this doesn't matter but usually you should always do Set to Frame Size.
The other option, and I've only encountered this a few times, is that Premiere sometimes freaks out with certain file types and doesn't like it when you "Set to Frame Size". What ends up happening is exactly what you just said: when you're paused the clip isn't scaled/cropped, but when you playback, it suddenly "punches in" and now looks cropped. The only fix that I've found for those situations is:
Right click > Remove Attributes... > Remove all Transform controls > and then choose "Scale to Frame Size".
I still have no idea why this second glitch happens, but my guess is there's an issue with the GPU or something...anyways...
Hopefully that helps.
i had the same problem for a while and i figured out a clip only adds zoomed out if it 60fps. i just right clicked on the clip and selected 'scale to frame rate' and it solves the issue

That's incorrect. The frame rate is incidental. The key factor here is resolution. Media which is larger than the sequence dimensions will appear cropped, or zoomed in. Media which is lower resolution will have black around it.
Most likely your 60 fps media is simply higher resolution than the rest of your media, which would account for the observation. But it would not be correct to believe that the frame rate was the cause of this issue.
Resolution is the key.
