"Start time": 0, "End time": 60 means it will only convert the first minute of the replay.
Set "End time" to -1 if you want to convert full replay.
"Process": 2 means the program will use 2 processes to convert so it will be faster than just 1.
Use "Process": 0 if you don't want parallel computing.
