I want to write a lua script that counts the number of frames an input is pressed in a movie... what am i doing wrong here? 
Language: lua
local upCount = 0

while true do
    table = movie.getinput(emu.framecount())
    if (table.up) then
      upCount = upCount+1
      print(upCount)
    end
    emu.frameadvance()
end

Try capitalizing up: 
Language: Lua
if (table.Up) then
It looks like you can get the proper names of the buttons by doing something like
Language: Lua
table = movie.getinput(emu.framecount())
print(table)
Obviously, you don't need to do this every frame once you know the names for whatever system you're working with.

I made a code that store all inputs from player 1 and print the input table only when movie ends 
Language: lua
local input_count = {
  ["A"] = 0,
  ["B"] = 0,
  ["Down"] = 0,
  ["L"] = 0,
  ["Left"] = 0,
  ["R"] = 0,
  ["Right"] = 0,
  ["Select"] = 0,
  ["Start"] = 0,
  ["Up"] = 0,
  ["X"] = 0,
  ["Y"] = 0
}

while emu.framecount() < movie.length() do
    table = movie.getinput(emu.framecount())

    if table["P1 A"] then input_count["A"] = input_count["A"] + 1 end
    if table["P1 B"] then input_count["B"] = input_count["B"] + 1 end
    if table["P1 Down"] then input_count["Down"] = input_count["Down"] + 1 end
    if table["P1 L"] then input_count["L"] = input_count["L"] + 1 end
    if table["P1 Left"] then input_count["Left"] = input_count["Left"] + 1 end
    if table["P1 R"] then input_count["R"] = input_count["R"] + 1 end
    if table["P1 Right"] then input_count["Right"] = input_count["Right"] + 1 end
    if table["P1 Select"] then input_count["Select"] = input_count["Select"] + 1 end
    if table["P1 Start"] then input_count["Start"] = input_count["Start"] + 1 end
    if table["P1 Up"] then input_count["Up"] = input_count["Up"] + 1 end
    if table["P1 X"] then input_count["X"] = input_count["X"] + 1 end
    if table["P1 Y"] then input_count["Y"] = input_count["Y"] + 1 end
    
    if emu.framecount() == movie.length() - 1 then
      print(input_count)
    end
    
    emu.frameadvance()
end

It's not a good practice to overwrite the variable table.

I agree with Amaraticando. This should have been the first thing mentioned here, as it could prevent future problems. Overwriting the table table effectively voids the whole library for table manipulation for the rest of the program, which you don't want to do.

Ok, I see your point guys. Then why do we use this line? 
table = joypad.get(1)
Or should we not?

We should not.

Oh yea I forgot to post the code I used to test and showed to you in the discord server, there I corrected it simply by using 
Language: lua
input_table = joypad.get(1)
