1-pass or 2-pass Encoding – Which one is better?

‘Nero Video’ provides two ways of video file encoding as shown in the screenshot: ‘Fast encoding (1-Pass)’ and ‘High Quality (2-Pass )’.

Two pass encoding makes sense if you have used many effects that need to re-render the individual frames from scratch, or if your input and output formats differ a lot. Two pass encoding does a double check to tweak out the last bit of quality. If your input and output formats are more or less identical it is not neccessary to do 2-pass.

Also note that 2-pass encoding takes the double amount of time to finish the encoding.

Moreover ‘Nero Video’ has ‘Nero SmartEncoding’ technology included that helps you save time and quality in case your input and output format are identical. When SmartEncoding jumps in it will not re-render your exported file and save original quality to file.
