Recording 720p source with 1080p I have started video recording some of my game sessions recently. Some of the consoles I am using output 720p and I was wondering what the effect would be, if I record them with 1080p:


How does that impact the file size?
How does that impact the sharpness of the imagery?
Do I gain some advantage this way?
Should I record 720p always with 720p?
It is best to match the source dimensions with your recoding dimensions. Using a larger number of pixels requires more data or bandwidth to encode the scaled source. You wont be able to make a sharper image as there isnt any additional information being generated and in fact the scale up might make the image softer or add artifacts like aliasing.
