120 fps montage experiment (play at 2x speed!)
Trying an experiment - not sure if it'll work out. Make sure to play at 2x speed! I recently started recording at 1440p@120fps and wanted to see if I could make a 120fps youtube montage work, so I put together some recent clips and this is the result. Hopefully youtube will allow 120fps videos by default soon.
*Why does the audio sound weird?*
When you play a video with a speed modifier, youtube attempts to keep the pitch the same. Since most people use the modifiers to speed up presentations/conferences/talking, this avoids them sounding like chipmunks (at 2x) or like they inhaled sulfur hexafluoride (0.5x). So in order to get the audio to not be modified when played at 2x speed, I needed to modify the audio by changing the tempo without affecting the pitch (done via Audacity). Since this is not a perfect process (as you need to create information that doesn't exist), the audio sounds a bit artifact-y. The algorithm does pretty well for musical instruments, but percussion sounds weird (especially game audio sounds). On top of that, youtube then tries to do the inverse process by changing the tempo by 2x without changing the pitch when you play it back, causing a bit more artifacts. How tolerable is it? We'll find out...
*Where is the original audio?*
The song is "Down to the Hydrocity's Nightclub" by Dr. Manhattan and can be downloaded for free from OCRemix: https://ocremix.org/remix/OCR01926
