Ask HN: How can I play TENET backwards?

15 pointsherodoturtle10 comments

Many of the scenes in the film Tenet make a lot of sense when played backwards - and it's easy enough to rewind these scenes to appreciate their visual effect - but the sound in those scenes is also reversed, and I'd like to hear it.

Is there a way to play a DVD backwards with the sound played backwards at the same time so that it's audible?

I am a Linux user with mpv if that makes any difference.

Search on Youtube for "Tenet Reversed"

But those scenes were not meant to be watched or heard unreversed, so you'll notice that the audio is still hard to understand, and even see some small mistakes in the stunt work and effects

This might be the easiest to watch, if you only want to see the reversed scenes: https://www.youtube.com/watch?v=j32zVGZoXJs

Thanks for this!

Will save me a lot of time ^_^

I mean, this’ll work, but it’s more in line with giving a man a fish instead of teaching him to fish.

Yes, you're right. But I wanted to warn him that this fish might not be worth catching.

If someone just wants a single fish, just give it to them. Don’t make it into a lesson about learning to fish.

Dude doesn’t want to watch every movie backwards, he wants to watch TENET backwards.

Get ffmpeg (e.g. a static release without lib dependencies from here: https://github.com/eugeneware/ffmpeg-static/releases/tag/b5....), then run:

  ffmpeg -i tenet.mp4 -vf reverse -af areverse tenet-reversed.mp4

Explanation:

  -i <input file>
  -vf <video filter>
  -af <audio filter>

Simple take: In those cases I'd use a mobile app that records sound and then plays backwards (there are several) and watch with that app ready on your phone or device.

Genius!

Simple yet effective.

And yeah it's less about the Dolby 5.1 quality, I just want to hear the damn dialogue in reverse haha.

Thanks mate!

This can be done with ffmpeg and it's "reverse" filter, it seems, according to:

GStreamer is able to play videos backwards. Use "gst-play-1.0", seek to the end, and press "d".
