How to change the frame size when rotating a video?

Question

Adobe Premiere

Placed the video on the timeline, size 1280x720. The frame, as I understand it, automatically also became 1280x720. But the video was filmed vertically, i.e. has not a landscape, but a portrait orientation, and in order to view it normally, you need to rotate it 90 degrees. If I rotate the video in Adobe Premiere, then it is cut off from the bottom and top, because. the video becomes 1280 pixels high, and the frame remains 720. And on the sides, everything is the other way around, the video is smaller than the frame in width and therefore there are black spaces on the sides. I just can't find in Premiere itself and on the Internet how to resize the frame to match the video size (in this case, to be 720x1280). Tell me how to change the frame size.

Answer 1

No way, most likely your video is written with an aspect ratio of 16:9 (or 21:9), but the main thing that this means for you is that there are really black fields in the video, this is not an empty space. The program does not distinguish them from the video that carries information. In your case, the procedure is as follows:
1) Rotate the video horizontally through motion - rotation. (What did you do)
2) Zoom in on the video using motion-scale until the black bars disappear and the video starts to fill the entire frame.
If the aspect ratio is not correct, then either change the resolution of the sequence in the sequence settings, or stretch it further through the same scale and cut off part of the video.
In the sequence settings, you can always set the resolution you need and manually crop the video as you like.
