I recorded a video in 1152x648 but I want to resize it to 1920x1080, also I can't record directly in 1920x1080 since my monitor is too small. It's an avi file btw.
1152x648 shouldn't have bars as it is 16:9 scaling up your video will drastically reduce video quality, but you can try this program, i have used it before, it offers an advanced resolution selection in the video converter.
