Hi emmrecs, thanks for the reply. Here is a link to a short exported clip with the issue...   Look all around the perimeter...  Thanks again...

an update...

I've installed MEP 2015 on a second computer and the same issue occurs... ..  Also, appears to be more noticeable on a clip with a darker background...

As stated in my original post - This happens only when I mix camera/zoom with  a gamma or brightness adjustment.  Used individually, the movie exports perfectly...    

 In the following link, basic gamma was increased and a typical zoom was used (any kind of zoom will cause the issue) - https://drive.google.com/file/d/0BwoDV3WR5dS6T2xKOG56SWI5cGs/view?usp=sharing

Hi,

I couldn't see what you meant from that brief video clip. The edges look generally out of focus throughout to me!

Maybe we could see the distortion if you show two comparative screenshots alongside each other?

I think I see what you are asking about (@terrypin, look carefully at the extreme edges of the picture, almost "outside" the video frame and you will see what I can best describe as a series of very small "twinkling lights").

Unfortunately, I can't suggest a reason for this but have you tried exporting to a different format?  Is there any difference if you choose to "remove/crop" the extreme edges of the frame, say about 5 pixels?  I have to say I also wonder whether this is somehow caused by the fact you are exporting to mp4, hence my first question about different export formats.

But yes, I am clutching at straws!  I don't have MEP 2015 so cannot check this but if you are able to post that same clip somewhere without the changes you made but give full details of exactly what zoom and gamma changes you added, I'd be happy to test it in VPX5 to see whether the same thing occurs there.

Thanks Jeff. I was viewing at the default Auto setting, but on switching to 1080 I see it clearly now.

@6fingers: I'll also try it in MEP 2014 if you're able to do as Jeff suggests.

Jeff,

Yes, first thing I tried, I exported to wmv, same issue. I also tried cropping etc, no change. As far as my gamma and/or zoom changes,  any change causes the problem,  just increasing gamma or even brightness by 1, combined with any zoom effect, causes the problem. I have tried just about every possible combination...   I'm beginning to suspect a bug in the software. I have also reinstalled the program AND installed it on another machine, same problem!  

Here's a link to the project files that I used to render the sample clip if you're inclined to explore...

Thanks for all your responses & time, Phil

Hi Phil,

I loaded your MVP into MEP 2014 Premium and exported it to MP4. That showed the edge distortion, but at a much reduced level to your example in MEP 2015.

Here are comparative screenshots of my MP4 export from your MOV, taken at 3:07 and 3:13 respectively.

--------------------

I then deleted all the files I'd downloaded except your MOV, imported that, and the resultant exported MP4 showed no distortion. So it's possibly project corruption of some sort, which has a greater effect on MEP 2015 than MEP 2014.

BTW, a more convenient way to upload a project is to use File > Backup > Copy project and media into a folder, zip it up and upload it to your host site.

Jeff,

Yes, still there, whether the same or less, still shouldn't be there...

When you say you imported the MOV file and exported it, did you increase gamma or brightness and add zoom before you exported?

I doubt a corrupted project since It happens in any new project I create with any clips I use or projects created in 2013 and no matter if original camera files are MOV or MP4 files...

Yes I did use the backup utility but I did not compress...

Thanks again, Phil
