1.
The image shows a scene from the movie Eyes Wide Shut. The file name is )esuohehtrofdrowssap(652ahs which when reversed gives sha256(passwordforthehouse). Googling Eyes Wide Shut + password for the house reveals that there actually was no password for the house. This means you have to apply sha256 to an empty string, then reverse it as indicated by the reversed filename and the backwardspriests.mp3. The page title says "Archive", which is a hint towards the fact that the png has a zip file in it. The password to the zip file is the aforementioned reversed hash.

From the zip file you get beep.txt. Beep is a hint for morse. The trick to the puzzle is that you are only given the spaces for the morse. Count how many empty spaces there are inbetween the underscores. You have to use Nutrimatic with each bracket query being a set of all letters with the specific length in morse code. Also spaces between words are given too. This gives you "newyorktheory".

2.
The image is a scene from the movie Mirror. Mirror is a hint for atbash. Rotate the text 180 degrees in order to see what the letters are and then apply atbash. Once more flip the decrypted letters 180 degrees, giving you something that looks like "undo plus aurora and unison album". Googling that points you to the album "vespertine", which is the name of a .txt file.

Atbash the entire grid and you will notice that the diagonal segment reads "rotate overlay match us". Rotate one of the triangular halves 180 degrees so that each location has two letters on top of each other. See which spots have the same two letters stacked and take those letters, discard the rest. This gives "illbeyourmirror".

The image shows bunch of different length hex strings. The key to the puzzle is noticing that all the strings are divisible by 3. Also the mp3 is called "triad", further confirming that you have to make strings of 3. The image name shows how to order the strings. Each 3 long string starts with an ordering number 0-f. Order the strings in this fashion and get rid of the 0-f numbers after that, leaving you with a 32 long hex string, which can be matched on crackstation.net for "cerebellum", which is the name of a .png file.

The png has bunch of pixels, the colour scheme being pure rgb+cmyk+white. For each pixel, see which rgb values are used, giving you 3 binary bits per pixel. The source code gives a hint that means "binaryfuck", so input the binary string into dcode's binaryfuck interpreter which gives "diedofastroke".

4.
Apply destructive interference on the .wav file and slow down the revealed audio. There's two songs from The Sound of Music, the first one just indicates that this is hill cipher. Second one is My Favorite Things, with some sections missing from the "favorites" list. Figure out which parts are missing and enumerate them. This gives you the numbers 1 4 11 13. Source code tells you how to place the numbers into a hill cipher matrix, decode the ciphertext for "thefrogchoir".

5.
The video shows a scene from the movie "Se7en". In it you can see an edited clip of a box with the text "Rijndael" and some hex numbers. Googling "Rijndael + box" leads you to Rijndael S-box, which should be used for substituting the given hex numbers. That gets you 6D 34 67 31 63 2E 70 6E 67, which is hexadecimal ascii for "m4g1c.png". Going to that file reveals that the file is corrupted somehow. The video mentions that a head might be missing so, so you have to add the magic or the "header" bytes of a png file to it, which are 89 50 4e 47 0d 0a 1a 0a. The working image contains the painting "Saturning Devouring His Son", which when combined with the file name of "m4g1c" should lead you to the Saturn magic square. Split the long number into pairs and see where the two numbers are located in the Saturn magic square. The locations indicate Semaphore flag locations, which decoded to "itsfreeforthegoat", which leads you to the final page giving you the final answer of "th3_winn3r_tak3s_it_all".
