Im trying to export a 4 minutes 12 sec video, to 1280x720 (189.49mb), and it's taking HOURS, 05:39:23 to be exact, and increasing all the time.
NO effects enabled.
Premiere elements 14.
I've got a mac book air (2014), core i5.
What on earth can I do? Surely this can't be the way it's supposed to be?
What format is this video? Is it an MP4, MOV or some other format?
While it's true that Macbook Airs are built for portability rather than power, you performance should not be this bad. In fact, a clip like that should take about 10 seconds to load.
There may be some strange compressor at work in your video, however. A 4 minute 1280x720 MP4 is usually about 400 megs. Is this video from a camcorder?
If not, it might be wise to download Media Info and open your file in it. Media Info will list the resolution, frame rate and audio and video codecs. With this information, we may better be able to figure out what's up with the file.
