I'm new to video production (and understand very little about computers)
I am using pe4 (most of what I do is trial and error)
I have video from 3 cameras that I have imported into one project. They are different formats (file types?) and show differently on the preview screen and on the television when playing a practice disc i burned
from my camera the files are avi and show as a normal picture filling the preview screen
borrowed camera 1 files are vob and show the picture as squashed filling the preview screen & making everything tall and skinny
borrowed camera 2 files are mpg and show the picture as normal but with a black area above and below picture in preview screen
I can live with picture from my camera and camera 2
But how do i change the camera 1 picture to normal and not squashed ?
You can not mix video types in version 4 of Premiere Elements. That was a feature added in version 11.
Version 4 is actually kind of primitive. I think you'll find most of your issues go away if up use version 11 instead.
(And, no, I do not work for Adobe and I don't make any money from your purchase. Your workflow just demands this upgrade.)
Meantime, in the short-term, you can right-click on the squashed clip in your media panel and select Interpret Footage. Change the Pixel Aspect Ratio.
This should solve your aspect ratio issue -- however, it won't resolve some of the other issues you'll see when you mix media from different cameras. In your output, for instance, you'll likely to see stutrrering or shakiness in some of the video formats you've added.
With PrE 4.0, and mixed footage, I would adopt a workflow such as this:
Note that if any Scaling is reqired, the quality from that camera's footage will decline a bit, but still probably be OK.
Trial and error
I ended up doing this
Rightclick pic in Sceneline
click show properties (couldn't find Interpret Footage)
untick constrain proportions
reduce scale height (from 100 to 81.2)
haven't done disc yet so i don't know what it's going to look like on the TV when i play it
wish me luck
PS Instruction book mentions that it accepts lots of different files... I can't see that it says I can't mix them in one project
(but theres lots of stuff NOT in the instruction book! .... at least it had one, it makes life a little easier)
Looking in your Project Panel (where all Imported media is displayed for that Project), just Rt-click on any media file/Asset, and you will see Interpret Footage in that drop-down.
