Side by side video to.....non side by side video

[tennesseemsu]

I have a video that is side by side, both the exact same thing. How can I either crop out one side or combine them to just have one showing?

you can use the crop filter in avidemux or virtualdub (need to add "null transform filter" in vdub)

I did that already with vdub but the quality was bad afterwards.

what do you mean by "bad"

use better compression

The original video is 720p but after I cropped it the picture quality diminished. What compression would you recommend?

[poisondeathray]

depends what you want to play it back on

some formats are incompatible with some devices. You've provided almost zero information on source format, destination format

you can use lossless compression or uncompressed - huge filesizes, difficult to playback

x264 is probably your best bet for quality/compression ratio ; you need the vfw version of x264 for it to show up in vdub , or you can use vdub's external encoder feature (use search there should be a guide somewhere)

lower quantizer = higher quality and higher bitrate (bigger filesizes)

Your side-by-side very likely does NOT have 2 identical images, it's a Left- and Right-eye view of a stereoscopic image. By combining them, it would quickly become clear that they're not identical, because the horizontal disparities would show up as sections of double- or blurry-images.

Of course, cropping and then resizing is going to give you an image that is softer than a corresponding original image. But it shouldn't necessarily be "BAD". That mainly depends on what you set the encoder settings...

1280x720 cropped in 1/2 is 640x720. Even resizing back to 1280x720 won't "recreate" those missing pixels, it'll just stretch those 640 horizontal pixels out twice as wide. Quality depends alot on your expectations.

Do what PDR and Corn said, crop what you want, but don't resize it. Crop it to SD. Don't render it out to 720p.

If you want to use the clip later in an HD project, that's fine, let the software resample it, or let it play in its own space.
