Hello!
I am brand new to Premiere Elements (2021) and to video editing in general. I just finished Steve's Lynda class on Premiere Elements 2021.
I'm trying to help a friend with a video project. She has a Powerpoint lecture recorded on Zoom that she will eventually upload to Youtube. She wanted a bit of extraneous stuff trimmed on the beginning and end. Before the video's uploaded, there will also be introduction and closing clips that aren't filmed yet.
Since I wanted to practice, having just finished my class, I did the small trims for her and exported the video to see what it looked like. First time in SD, second time in HD. The exported videos are MUCH larger than the original.
from19.3 MiB original to 287 MiB HD or 187 MiB SD
The video is losing its compression? So, my questions:
1. What settings should I be using to export, if my input is or includes Zoom-generated video?
2. What's going on that's making the exported videos get so big?
3. Can I make them smaller?
Also, I expected to see one channel of audio in the audio mixer tool, but both left and right are populated, which surprised me. Not really a problem, but ????
Thanks,
jana the newbie
