Hi Romano,
I am using Windows 10.
For recording I used Open Broadcaster Software which is a screen capture tool. You can set the encoder and the file type. That is set to .mp4 and H.264. What I read in the specification of Elements is that those should be supported.
a. Not a camera but as said above a screen capture tool
b. it is a constant frame rate of 50
c. the audio is stereo
And I didn't even get an error. The Premiere just stops working when I try to import.
Speaking of I just take the video clip and drag and drop it to Premiere (which works for some other videos too).
I didn't do much with the the project preset because I am just starting to work with Premiere. So this should be kinda default..whatever this may be.
I have some videos where it worked but those are already rendered in .avi. (which is atm not an option to record in).
It is for every project.
Thx so far
