I put a video I took with my iPhone onto my mac, and wanted to edit the audio in it at some points (my voice is way too overbearing) so I imported it into iMovie... but now it's all stretched out... help?!
You probably need to make sure your sequence settings are set to a 16:9 format. If they are set to 4:3, then the video will looks stretched vertically or the sides will be cut off.
Yup. I used the back camera to record it, held the phone upright the entire time (vertical orientation)... and I transferred the file to my Mac using Image Capture... then imported it into iMovie and it was stretced out to fit the screen, so as to not have two vertical black bars on each side.
