Weird Borders on Videos When Adding Video Crop and Motion

Hi All,

First time, long time.

I am trying to put an animation I made in Powerpoint into a Powerdirector 13 video. The animation is on a white slide background. To show it, I want to zoom in and out and move/pan the animation over, on top of a white colorboard/background. However, doing so, I get this weird border that comes in and out, especially as the video pans up and down/side to side. It's pretty obvious when you watch the video.

I think it's a Powerdirector issue - frame rates/file types/aspect ratios not matching up. But, it shouldn't happen in this level of video editor.

I tried to output the "raw" video file made from the presentation as a M2TS file by simply adding it to PD and exporting, but the same effect is seen.

Anybody seen this before, and is there any way to fix it, or otherwise work around it? Masks, channels, anything? Any help is very much appreciated.

Here's the youtube, it's still uploading: http://youtu.be/7URYolSV83M

Thanks,

-TheZeigs

If you mean the small black line on the left and top, that is caused by a miss-matched aspect ratio. 4:3 image must be really 4:3 to completely fill the frame. The image can not have any border.

PNG images work best in Powerdirector for PIP designer. Carl312: Windows 10 64-bit 8 GB RAM,AMD Phenom II X4 965 3.4 GHz,ATI Radeon HD 5770 1GB,240GB SSD,two 1TB HDs.

Hey thanks for the quick reply. FWIW, you have personally answered a lot of questions that I've searched for and fortunately others have asked, so I appreciate your help.

I guess I should have said, you have to move forward in the video to see the animation. I should have cut this out - but the animation starts at 30 seconds. Around the "frame" of the animation, there is a weird border that shows up. The white-on-white of the animation and color board really makes it stand out.

Hope that clears up my question!

Hi theZeigs123 -

Your question is clear & so are those artefacts at the edges.

It looks like you've set the motion in PiP Designer, rather than Video Crop. In any case, the best way to eliminate it is to mask the edges of the white backed video in PiP Designer. Uncheck maintain aspect ratio & set the mask edge just inside the video edge.



Cheers - Tony

[Quote = theZeigs123] Any help is greatly Appreciated. [/ Quote]

ynotfish showed great option.

I also cut a video edge, a line around the image, thus eliminating any irregularities on the edge..

Thanks for the response, PlaySound, but unfortunately simply cropping the edges doesn't work for my purposes. I have a video that has various crops and motions, so I already cut way more than just the edge! Appreciate your input though.

ynotfish, also have read a lot of your responses and seen your tutorials, keep up the good work, and thanks for the response. I did in fact do the motion in Power Tools, but I would be OK re-doing it using PiP tools if necessary.

The one thing I don't get - is there a way "to keyframe the mask." In other words, if I create a mask, I need for it to be immobile with respect to the clip itself. Unfortunately, the mask sits on the same place relative to the screen so as the clip pans and zooms, the mask just sits in the same location. Is there a way to have the mask move as I zoom/crop (or use PiP motion/size tools, alternatively ) so that the mask always sits on the edge of the video?

Per this thread: http://forum.cyberlink.com/forum/posts/list/41420.page;jsessionid=9D05F84621379871DAB3D99F4A92782B

I tried to use an overlay, with a green center that I chroma'ed out of the picture so that I could move the overlay around and achieve the same effect as a mask. This would work, but you can see the results in the video below: the lines created by the mask are actually worse than small amounts of lines I started with!

Am I missing something with the chroma? I created a 4k picture in GIMP that I put a green box in the middle of. I then chose this color. Even with the hue and saturation values maxed out, I still see lines at the edge of where the box was. Even if I use a "clear" chroma - create a transparent box in the middle of my "overlay" in GIMP, I get the same effects (though the video below was done with the chroma key) (I also made this video using PiP tools just to be sure!)

I think the problem is that I have a video with a white background moving across a white background - a pretty rare thing. In any case, there has to be a solution for this. All suggestions welcome.

Thanks - nice to get a little positive feedback. laughing

I'm having a little trouble visualising your timeline setup or, at least, the exact steps you've taken. Does your timeline look a little like this - where the video in Track 2 has been previously cropped then produced?



I'd forget the chroma key idea. All that's doing is complicating matters further.

One thing that would be worth a shot would be to replace the 255, 255, 255 colour board with a 1920x1080 rectangle made in Gimp (or whatever). Use the exact same colour as the background of your video, even if it is 255, 255, 255.

To me, it looks like your animation video is moving around within the screen (i.e. set in PiP Designer). Video Crop behaves differently.

A timeline screenshot would help - with some more explanation of the steps you've taken.

Cheers - Tony

Yes the way ynotfish Showed in the first answer, uses Pip Designer, rectangular masks applied to the animated video, she keeps Following size and video movement, always on the edge.
