Which version of the program are you using?
If you look under the Edit menu, what Project Properties are listed?
What model of camcorder is your video coming from?
Have you manually gone to the nVidia or ATI web sites and ensured you have the latest driver for your video card? Have you ensured you have the latest version of Quicktime, per the program's requirement?
After replying to prior questions, I have some questions also, not already pointed to.
1. From what you wrote, it sounds to me like only one video file on the Timeline is affected, and no other video files on that Timeline are affected even if those other files have the same format as the problem file. Is that correct? If so, that would seem to take the video card/graphics card out of the troubleshooting equation.
2. Knowing the version of Premiere Elements and on what operating system it is running are important. For now, I will assume Premiere Elements 11, 12, or 13
on Windows 7, 8, or 8.1 64 bit. If you select and highlight the problem video on the Timeline and go to Adjust Tab/Adjustments Palette/...and display of panels, do any of the panels have a green dot on them? If so, which one(s). Aside from that, did you knowingly apply any effect(s) to the problem clip that you did not to the others? Here I am suspecting a Smart Fix being applied with or without your knowledge.
As a just in case note about what you see in the Preview Window when you double clip the file thumbnail in Project Assets or on the Timeline -
You see the source file without applied effects et al. That is normal.
If you press the play button of the Edit area monitor, you get the playback on the Timeline content with its applied effects et al. That is normal.
Consequently, my initial target in your troubleshooting is what has been knowingly or unknowingly applied to the problem clip in the scenario
that I suspect and have stated at the top of this post.
We will be following your replies to all contributions.
Add On...post revisited after original posting to remove an extra "even" in one sentence.
I use PE 13.
As A. T. Romano wrote, some video files are affected, some are not affected. I did not use any effect. Just moved video file to timeline. All video files were made by canon eos550d in full hd quality and the project is also in full HD. I have the latest drivers for AMD RADEON R7200 SERIES and quicktime.
Within a 99.999% certainty I believe that I know what happened to that particular video clip.
Somehow Videomerge was applied to it.
Probably when you dragged the clip to the Timeline you clicked Yes to the friendly but dangerous Videomerge message...it probably
saw your solid colored brown background.
Let us see if my 99.999% certainty is right. Select the problem clip. Go to Applied Effects Tab/Applied Effects Palatte, and look for a Videomerge
Panel. Do you see one?
We will be watching for your report.
Guessing, but with certainty...Before situation, you clicked Yes to..
And, after got
You can get back your "good" video clip, by right clicking the Videomerge Panel, selecting Delete, and then clicking on
the image in the Edit area monitor.
I love youuuuu...
