I would like to watch recorded lectures at 1.7x of their original speed.

Which app will allow me to do that?

    1.7x their original speed? Must be a boring lecture, eh? ;)

I can't find any playback app on the iPad with the exact 1.7 ratio...

However, Azul for iPad (app store link) has 1.5 and 1.75 playback ratios. They even say in their site blurb that it's good for fast reviewing of lectures.

Reviews are excellent and integration with Mail and Dropbox is there, as well as a very comprehensive codec list


I built Swift Player for iPhone and iPad that will allow you to change (speed up) the playback speed of video and audio from the device or even directly from websites like YouTube, etc.

You can find out more information on the product's website.

Note: This is a product that I have developed.

  • Does this app just speed the audio/video? May 18, 2013 at 16:11
  • Not quite sure what you are asking. Its main function is to adjust playback speed of audio or video files. It has other bells and whistles like downloading for offline viewing, etc. Check the site for all the features.

    Well, I did state it's a shameless plug, and it's not like i'm saying this out of context. I built this app because I was lacking a solution for the very same reason this thread is about. And the question the user asked was of an app that does this. Every other answer is of an app, are you sure they aren't "marketing".

  • @dizy, I'm sorry, I left a word off ("up") in my comment - so I wasn't clear. I understand now. May 20, 2013 at 14:47

Speedeo just came out for both iPhone and iPad and allows you to increase / decrease videos in 0.25 increments. You can also resume watching videos quickly from the history screen. You can view videos from 0.25x to 2x speed, quite neat for watching presentations / tutorials.

Note: I am one of the developers of this app


VLC will allow you to playback at any speed between 0.25x and 4x in increments of 0.01x. Choose the clock icon from the lower toolbar during playback to see a slider.

VLC can be downloaded from http://www.videolan.org/vlc/download-ios.html (links to Apple's AppStore

  • Unfortunately, the VLC Media player port for iOS is a bit basic. As of 2012-06-08 it does not support variable speed playback (pity, as it is a nice app in most other respects).

PDF Expert, despite the name, has a great video player with variable speed (0.5x, 0.8x, 1.0x, 1.25x, 1.5x, 1.75x, 2.0x) and also 2-finger swiping gestures for seeking and brightness, and double-tap forward/back gestures like the YouTube app. Many ways to import and manage videos/files.

I'm not affiliated; just love how much effort and polish they have put into this free app.


AVPlayerHD supports 1.05 to 2x in 0.05 increments (and is available in the Swedish Itunes Store, which Swift Player and Azul aren't, and I assume other non-US users will have the same problem.)

I am not affiliated with this app.

As an author I could recommend a new Free iOS player with variable playback speed and many other adjustable playback options alphaSXplayer
