I'm using Adobe Premiere Elements 10 on Windows 7. I've been trying to black out an LG logo from my video for copyright purposes. I utilize the effects mask over the logo and use the brightness/contract effect to just black it out. It works in the preview, but when I save as a MOV or MPG file, the blacked out square has moved to a different part of the screen. Please help. Thank you.
This is very common when you're using MPEGs (including M2T files) as source video.
What model of camcorder is your original video coming from?
If you're truly using copyrighted video material and you're trying to override its copyright, I'm not sure we can help you. Respecting others' copyrighted material is an important part of working with digital media.
It's a Canon T2i Rebel DSLR. The file format from the camera is MOV.
I am entering the video into a film festival and forgot to cover up the LG logo on a large TV box in the background of a scene.
The best solution is to use Share/Computer/AVI to output your finished movie as an aVI. (Do this BEFORE you try to mask the logo!)
Then open a new project. Make sure it's set up for DV. Add this AVI to it and mask out your logo. When you output any file from this project, the mask will be right where it should be.
I'm not sure what to tell you. If you add the effects mask to a DV-AVI rather than an MPEG or an MOV, it's always right on the nose.
What happens if you output another AVI from your AVI project?
I right click on the clip in Timeline, choose Effects Mask > Apply
The rectangular mask appears on the screen, I drag one corner in to make it smaller - what the exact dimensions are I know not. The logo I need covered happens to be almost at the exact center of the screen.
I choose the EDIT Tab > Brightness/Contrast > Set the levels so the mask is perfectly white (thus, covering up the logo) > Apply > Done
The preview works. When I output as AVI, MOV, MPG, MP4, etc., the mask that I placed over the logo has now moved either above where I originally placed it or above and to the left.
I have no idea how to answer the second part of your question.
I just tried the Effect Mask on an MPEG in a 1920 x 1080 (on the Extract Effect), and saw the Mask move several pixels in an AVCHD Export/Share.
I applied the same Effect and Effect Mask on an NTSC DV-AVI Widescreen 16:9 Clip, Exported to NTSC DV-AVI Widescreen, and there was zero movement - the Mask was rock steady.
Will try some other combinations, to see if I can get that Mask movement.
