Slo-mo Mod: enable slow motion video capture on unsupported devices

By , Jan 24, 2014

Slo-mo Mod 02

One of the iPhone 5s’ flagship features, the Camera app’s baked-in slow motion mode, is now available to owners of older devices like the iPhone 5, and the iPod touch 5th generation. Slo-mo Mod is the jailbreak tweak that makes it so that slow motion mode is no longer an iPhone 5s exclusive.

I have to admit, I was a bit skeptical when I first heard of this tweak, but after giving it a shot, I came away thoroughly impressed. No, it doesn’t allow you to have 120 fps video capture, but it will do 60 fps on the iPod touch 5th-gen hardware, and that’s more than enough frames to come away with some excellent looking slow motion video.

Slo-Mo mod features a preference panel in the stock settings app, and you’ll want to venture there briefly, to make sure that the FPS settings work for your device. If you’re running an iPhone 5 or an iPod touch 5th-gen, then 60 FPS works fine. I tried to bump the FPS up to 120 on my iPod touch, but the Camera app just crashed after doing so. If you stay under the 60 FPS threshold on this last-gen devices, then you should be fine.

Slo-mo Mod Prefs

If you’re running an even older device, like an iPhone 4S, you’ll definitely want to keep your FPS settings set to 30 FPS. You can try tinkering with a frame rate higher than that, but your results may vary.

Slo-mo Frame Rate

Once you have the frame rate information configured, you can head to the stock Camera app to start enjoying slow motion mode. As I stated at the outset, I was very impressed with how true to form this tweak is. It replicates the look and feel of the stock iPhone 5s feature to a tee, and even if you’ve never used the slow motion feature before, it’s intuitive, so you’ll learn fast.

Just swipe over to the “Slo-mo” section in the stock Camera app, and start shooting video. You’ll notice that the frame rate is much higher than normal, so the view finder will seem a little herky-jerky as you focus on your subject. It’s not as noticeable at 60 FPS as it is with 120 FPS, but it’s still noticeable.

Slo-mo iPod touch

After shooting your video, you can view it and move the vertical drag handles in edit mode. The vertical handles indicate where slow motion video starts and ends. Anything between those drag handles will be reduced in speed.

Slo-mo drag handles

The amount of slow motion effect depends on the slo-mo rate configured in the tweak’s preferences. By default, the rate is set to 0.25, which means that you multiply the frame rate by the slo-mo rate to get the frame rate of the slow motion video. In this case, my frame rate will be 15 FPS, because 0.25*60 = 15 FPS. The larger the value, the smoother the playback, but also the faster the playback. I recommend keeping this value set to default.

Slo-Mo Rate

Slow-mo Mod features a couple of additional toggles in its preferences. You’ll find a setting for video ramp up volume, which allows you to set the volume of the slow motion portion of the video. Again, I recommend keeping this setting set to stock value.

Slo-Mo Ramp

You’ll also find a setting to force slow motion mode for all videos. With this option enabled, all recorded videos will be marked as being shot with slow motion. This allows you to set the aforementioned drag handles to designate portions of the video with slow motion. The effect this will have will vary, but generally it won’t be very good with video not shot with slo motion in mind (higher frame rate video).

Force Slo-Mo

Lastly, you’ll find a toggle to disable Slo-mo Mod altogether. This kill-switch is useful for troubleshooting issues with Camera app lag on some devices. You generally shouldn’t need to use this unless you experience issues.

Although the resulting slow motion video wasn’t as silky smooth as you’ll find with the native slow motion mode found on the iPhone 5s, it’s hard to complain about this jailbreak tweak. Slo-mo Mod is giving you one of the iPhone 5s’ most noteworthy features for free, and it works much better than one would expect on previous generation devices like the iPhone 5 or iPod touch 5th generation.

If you’ve yet to upgrade to the iPhone 5s, then I definitely suggest you check out Slo-mo Mod, which is free of charge on Cydia’s BigBoss repo. Chances are you’ll be just as impressed as I was. Let me know what you think about it in the comment section below.

    Does the 60FPS lag continue to appear in video after you film?

    • Ali

  • Dylfo

    How does it work on 4s also can you use the front facing camera?

  • Fermín Osorio

    What is the burst mod?

    • Juan Flores

      It won’t send the slo-mo version because it is only supported on iPhone 5S. The videos only stay on the iPhone 5S.

      • Fermín Osorio

        Oh… Then the weak is not useful :/

      • Ralph YoungnRecklezz Smith

        Send as email then copy it from email to messages and it will work

      • Diance

        That didn’t work for me. What phone are you using? Did you do anything before you sent it to your mail?

      • Sérgio

        Just use TruSloMo from AppStore.

    • fernando

      You can share it with email, it will send with the slow mo playblack

    • filter351

      Try emailing the video, worked for me.

  • filter351

    Yeah, you can’t share slo mo videos. I’ve been using this for a couple of days and have tried everything with no success.

    • fernando

      Use email its the only way i found

      • filter351

        Thanks, worked great

    • Mhmd Bassam Nasyr

      send via iMsg, save to camera roll, send via email,viber,whatsapp etc

  • Zower

    the name of the tweak is Slo-mo Mod. Not Slow-mo Mod.

  • filter351

    Did I miss something in that last comment?

  • LAGISSUEZ

    Thanks Jeff! I’ll tell you what though, phuck the slo mo, just noticed how awesome the video looks in 60fps if you just remove the slow mo portion. SICK!

  • iPT MSTR

    Gonna get dis 4 my ipod 5

  • filter351

    Awesome, email does work. I must have missed it in my trials.

  • Jonathan Talbot

    You forgot to mention it works on iPad. I have it on my iPad Air and it works extremely well!

    • Svs

      Can you get 120 fps on it?

  • Ariel

    With the app SloPro 2.0 an iPhone 4s or higher can record true 60fps, works great. Though it would be more convenient to have the same functionality straight in the camera app. Perhaps in the following updates?

  • Svs

    Help i cant see the drag handles

    • Jonathan Talbot

      On the settings app, in slo-mo mod, select the option where all videos become a slo-mo video

  • Mads Teland

    It does work with iPhone 5s, just make sure to set to 120 FPS ;)

  • usiak

    shit.. it crashed my camera app, when i was edit preferences badly. What now?

    • usiak

      changed back to default preferences, but front facing camera is down.

  • Jordan Carter

    For those that aren’t jailbroken and want a slow-motion camera you can install the app SlowCam from the App Store for I believe $1.99 or $2.99. Works very well.

  • krill38

    Question, does it make the iPhone 5 feel more laggy or no differance?

  • iamse7en

    Hmmm…. Should I actually update to iOS 7 now? Still hesitant.

  • peter

    there should be a way to export the video to your camera rol for sharing or posting on facebook. its rediculous to say it has to stay on the device that cretaed it, when 90% of all videos and photos are shared online. come on.

  • Rick Wheeler

    ok i finally got the settings right, so camera dont crash…but now whenever i edit the vid, it does nothing, makes no difference to the video, plays at same speed regardless of what i do?!? any ideas why?? 5c 8.1
