What tool are you using to trim the clip? You may want to try and close the program monitor and reset your current workspace. Windows>Workspace>Reset Current Workspace
it does not matter which trimming tool i use...
I have already tried resetting the workspace, restarting the program/computer...
it´s a strange problem... they appear as frame on frame all the time. i can see a portion of the inpoint, behind the outpoint and behind that i see the top of next/previous clip.
It might be a overlay problem (video card). Do you have a dual monitor system? If so try putting all of premier on one screen. If that doesn't work you could try to go to the program monitor output and clicking on playback settings. On a dual monitor system (if premier is on one screen) you can select your other screen as an output. If this helps it is a video card issue. You could try upgrading or downgrading the drivers for a more permanent solution.
Actually i have a triple monitor system, the third is a Wacom Cintuiq, but what is bothering me is that few days ago everything was fine. I always have my premiere on the main screen only because other apps, like soundbooth is open on the second monitor. I will try to se if there is a graphic card upgrade. I tried going into playback settings and outputting to another monitor without solving the problem....
i will try to load a old project to se if it has the same problem.
allright.. now i have found out why this happens but i do not know what i can do to correct it. I tried to open an older project and everything looked as it should be so i started looking into what was different with these two projects. The main difference is that in the on i am working on right now I use proxies files and therefor i have "scale to frame size" turn on, if i turn it off It looks normal when i trim the clips. If I click it back on, it becomes cluttered again.
Is there something I can do so i can work with proxies again without having to deal with this problem.
My original files are Canon 5D Mov. footage which i have converted to x264 codec (1920x1080p)
my proxies are also in x264 codec but the frame size is 960x540p
All material is converted to 25p (not the native 29p) but i don´t think that has anything to do with the issue i am having. It was not my intent to convert it to 25p, it just happened that way, but since it is like that i also us 25p for the Sequences.
I do not work with proxies at all so I have limited knowledge on this topic. But you might try bypassing scale to frame all together. What if you created a project the size of your proxies, edit the project there and then copy and past your final edit into a new project the size of your final output, then relink with the higher res files. Like I said I have never used them because my computers handle HD just fine.
