When you say the “canvas” is 3 hours are you referring to the entire working area of your composition or are you referring to the layer? If it’s the layer, go to the 10 minute mark, where the clip would ends at the time remap and press “alt + ]” to trim the layer to the CTI(current time indicator).
If you meant the composition, press “Home” and then “B” to set the beginning of your work area(if you haven’t adjusted your work area, it will already be set there). Then go to the 10 minute mark, and press “N” to set the end of your work area. Lastly right click in the work area defined portion of your timeline and from the drop down select “Set Comp to Work Area”. Now your comp should be 10 minutes.
Alternatively, you can press “cntl + k” to open up the comp settings and manually change the duration of the comp to 10 minutes.
