More likely, the makefile was exactly as he said, and with tabbed
indents.  The missing colon on line 5 would cause that error.

This is probably the makefile Brian is attempting to write:

proj13.exe: video.o testmain13.o
	gcc -o proj13.exe video.o testmain13.o
video.o: video.cpp
	gcc -c video.cpp
testmain13.o: testmain13.cpp
	gcc -c testmain13.cpp

but at Eli has pointed out, the last 4 lines are redundant because make
already knows how to compile source files to objects.

Of course, make can do more than this, and I can't help but point out too
that Brian probably wants to turn warnings on since this so easy to do in
a makefile.  Here's a slightly more advanced version (but not more
advanced than a beginner could cope with after browsing the info pages, I
think):

CFLAGS = -Wall

proj13.exe: video.o testmain13.o
	gcc -o $@ $^
