Filmmaker Tools

The built-in time lapse calculator will compute the total number of images based on exposure, delay, and overall time.

The file size calculator allows you to select your camera type and file type. It then computes the average per image size along with the total size for the calculated time lapse sequence.

The play back calculator determines your video clip length based on your selected playback frame rate and calculated time lapse.

The motor speed calculator will estimate the Kessler Basic Controller dial setting to achieve more accurate motion control. Selectable variables include slider device, motor series, travel distance, overall time, pulse mode speed, payload weight, and slider angle.

The included level tool allows you to quickly level or set angles of devices in both landscape and portrait mode without leaving the Kessler app.

Flashlight Mode (iPhone only): working in low light? Quickly flip your iPhone's flash on without leaving the Kessler app to shed some light on your work.

  • Out of date?
    by Christian-stone on 2017-02-12 at 9:59 PM

    Used to be helpful but I find it's buggy and simply won't work for me anymore. Entering time lapse settings is unresponsive. Also the button design is a bit cumbersome on the time lapse page. The set button is on the very top and really small. I love Kessler and use their gear but this app is not holding up. […]

  • Great App
    by MYBT2004 on 2016-07-31 at 4:49 PM

    Use this all the time in planning time lapse sequences! Simple and accurate. […]

  • Resets frame rate when returning from tools
    by fpsurgeon on 2016-04-10 at 8:13 PM

    If I change the playback frame rate to 30fps and set it, then I go to the flashlight tool, when I return to the time lapse settings they're reset to defaults! […]

  • Great app.
    by Ellison_Family on 2016-02-24 at 1:21 PM

    Use it for my second slide. […]

  • Not everything works
    by rlpeebles on 2015-05-11 at 7:16 PM

    You cannot calculate "overall time" or "delay" exactly using the "video clip length" because "video clip length" will not open in order to fill in the information. You have to make educated guesses on the "overall time" and/or "delay" until you get close to the "video clip length" you want. I have tried the app on an iPhone and iPad and both have the same problem. Would be the best app out there for time lapse if everything worked. ( I have the latest version) […]

  • Dream come true
    by ModemmeX on 2014-04-25 at 1:38 PM

    Been looking for websites that would do these calculations. Now I have this dynamic app. You can figure out all things timelapse by entering any variable in any order. Love it with all my heart. Thank you Kessler! […]

  • The app
    by صباح الجنديل on 2014-03-04 at 8:53 PM

    This application needs a lot of reforms...The beginning of large images can not be content to see clearly......There are no prices on the product and not the product Alxsswart.....Feature offers wonderful video ... by the way..... Thanks .... […]

  • Powerful tool to compliment Kessler gear
    by bigpike1234 on 2013-11-23 at 2:43 PM

    If you own anything Kessler, or if you plan on buying some quality gear, this app is great to have in your back pocket. Easy to navigate, helpful videos and powerful tools. Well done. […]

  • Pretty sweet
    by Keeleyboy on 2013-04-08 at 3:08 PM

    Does the job well. Tried to switch motion control option to oracle but it looks like it's only for basic controller. Don't know if its just me or what […]

  • Light manipulator
    by Rtyler87 on 2013-04-03 at 1:51 PM

    Excellent app. Does everything you would expect it to and more! I have quite a few Kessler products and find the videos extremely useful when I'm on the go. The fact that its also free makes this a no brainer for any serious timelapse enthusiast! 🙂 […]

  • Delay

    Doesn't allow delays greater than a minut […]

  • Just a sales tool that's light on usable features
    by AppTank on 2013-01-06 at 7:38 PM

    A real filmmaker would be better off getting a proper full featured app like pCAM. This looks to be more of a quick way to push products. […]

  • So useful and easy!
    by Jroo96 on 2012-12-02 at 2:59 PM

    All the instructions, video tutorials, and info on products is at your fingertips. Easy to use and some great timelapse tools are included. Sweet app. […]

  • Awesome level!!!
    by Quick flashlight draw! on 2012-06-24 at 2:42 AM

    I actually only downloaded this because I heard it has a free level... And it does! I wish it worked when I held the phone vertical as well as horizontal, but either way, my life will never be the same! I am forever indebted to the Kesslers for this app. […]

  • Holy sweetness!!

    What an unexpectedly awesome surprise!! Great app!! […]

  • Nikon Shooters Don't Shoot Timelapse
    by gambit11 on 2012-05-31 at 2:59 PM

    First off, let me say that I love Kessler gear. I own a ton of it (cineslider, k-pod, 12' crane, k-flex track, etc.) and it is great! However, I was disappointed to discover when playing with this app that evidently if you own a Nikon camera you don't shoot Timelapse photos... Disappointing to see only Canon camera options listed under camera type when calculating file size. Let me know when Nikon shooters are allowed to shoot Timelapse... This could be a very useful tool! […]

  • Eric you rock!!!
    by FullHD911 on 2012-05-31 at 7:14 AM

    This a beautiful app, work amazingly well. Big thanks to you Eric and your team!!! […]

  • Excellent app!
    by mabou on 2012-05-30 at 9:54 PM

    I think Kessler did a fantastic job with this app. They didn't need to spend the time, resources, and money to make this app, but they did it anyway to create a better user experience for their customers. Hats off to Eric Kessler and his team. Matt […]

  • Thanks Kessler
    by Truckincars on 2012-05-30 at 5:25 PM

    I'll definitely use your app daily. Great! […]

  • Nice app!
    by ScareFX on 2012-05-30 at 2:49 PM

    I really like having the motor speed tool on my iPad. If you have the basic controller, it's really essential for estimating your dial setting. The timelapse and level tools should be handy as well. Nicely done Kessler! […]

  • Needs UI fixes
    by NeedApple on 2012-05-30 at 1:14 PM

    Great reference app overall and the calculators are great value adds for free. Needs manuals for some products. Buttons for the tools secondary menu work but are far too small. […]

  • Awesome !
    by KAREN ABAD on 2012-05-30 at 11:00 AM

    Makes timelapse calculations a breeze! Love the motor calculations as well. Kessler rocks. Nice product/tutorial video integration. […]

  • Love it!
    by tylerginter on 2012-05-30 at 6:07 AM

    Such a handy tool for filmmakers! Thanks Kessler!! […]
