Why won't my HD video scale up to full screen?

[johnharlin]

I used my Casio FH100 digital camera today to make some HD 1280 by 720 video clips which come out in .avi. I then did some editing with AVS Video Editor to combine the HD video clips and high speed 120 frames per second 640 by 480 clips. I muted the noise of the video and added some slick music. It came out decent. However, one thing that bugs me is that it won't scale up to full screen. Is there a setting I'm supposed to be wary of like letterbox or something like that. I never had a problem scaling videos up to full screen.

The camera outputs 1280x720 in MJPEG format in an avi wrapper. Audio is PCM.

What format did you export from the AVS Video Editor and how are you playing the resulting file on the TV?

If on the computer, what player are you using?

[johnharlin]

I'm playing the file on a computer with VLC player but I tried several other players with the same result - like it has a black box around it to keep it at it's appropriate size. Eventually, when I am able to add all the bells and whistles, meaning I'm having problems installing successive transitions between photos I installed at the end of the video, I want to convert it to DVD.

The issue is with the export settings with the edit program.

DVD settings would reduce resolution to 720x480.

Black on 4 sides results from 16x9 to 4:3 as letterbox top and bottom, then 4:3 played as 16:9 resulting in side pillar addition.

To do it right you would set a wide DVD edit project, import the the 1280x720 and 640x480 to the timeline. The 640x480 should show side pillars, or you could stretch it wide. Then export encode to DVD wide format MPeg2.

Your source images are 16:9 display aspect ratio (DAR). You created a 640x480 video clip (4:3 DAR). When the software put the 16:9 source in the 4:3 frame it letterboxed the images. When you play back the resulting video the player sees the video is 4:3 DAR. So when it displays full screen it pillarboxes the video. So you get a small picture with both letterbox and pillarbox borders.

in vlc, to fill the screen you can press the "c" key. but since you're reducing the final size, maybe it would be better to size it down to 640x360 so that it fills the screen properly when using "c" key. keep pressing it until it fills the screen the way you want. but if you size (AR) incorrectly then the the fill screen will not come out right.

in kmplayer, you do something similar, pressing any one of these keys will resize/fill the video to your screen:
1, 2, 3, 4, 5, 6, 7, and each have their (strech / overscan / scaling) intended purposes. again, (if downsizing) its best to resize down to the relative aspect ratio so that the player can fill the screen properly w/ minimal distoration or loss of detail.

i prefer kmplayer because it has more resize options.

Many software players have a zoom feature in them. If you just want to use what you have and not reencode you do zooming to get back to the widescreen inside the matte.

Of course as eddv and jagabo pointed out proper authoring from the start is the correct way to go. Zooming is just for testing on the files you already made. Starting over with the original source is the best idea.

When you mix squares with rectangles, you have to trim the squares top and bottom into the shape of a rectangle or they won't fit.
