Online Video Looper Pedal

This is a DIY clone of the Vidami Pedal by Utility Design giving you handsfree looping and playback control on Youtube and Vimeo videos. It features one more button and also a bank switch to switch between 2 sets of keymaps. I personally use bank 2 for mapping the foot switches to specific functions in my DAW.

Reviews of the Vidami Pedal

Parts to get

1x Arduino Pro Micro
1x 1590XX or 1590DD enclosure
6x Soft momentary footswitches
1x Toggle Switch On-On
7x 10kOhm resistors
1x USB cable (USB-A to Micro-USB)
some wire for soldering it all together

Hardware Installation

Arduino

check the pin layout of your Arduino (Pro) Micro
- NOTE: the one linked above is different from the official one
- pinout for above linked Arduino Pro Micro
- latest pinout for official Arduino Micro
connect / solder wires to
- 5V pin
- GND Pin
- 7 digital inputs
  - e.g. 5, 6, 7, 8, 9, 10, 16
  - if you choose custom ones you will have to modify the Arduino code
connect the other ends to your footswitches and resistors as shown in the following schematic:

Enclosure

drill 6 holes for the footswitches
drill 1 hole for the toggle switch
drill a hole for the USB cable
mount the Arduino Micro so it won't move (e.g. a small breadboard)
mount the footswitches
mount the toggle switch

Software Installation

load and flash OVLP.ino onto the Arduino using Arduino IDE 1.8.13 or newer
- install library Keyboard 1.0.2 or newer
- install library MIDI Library 5.0.2 or newer
- install library USB-MIDI 1.1.2 or newer
install Tampermonkey extension in Chrome/Firefox/Edge/Opera/Safari
import OVLP.user.js into Tampermonkey

Usage

Use the toggle switch to switch between bank 1 and 2 enabling different keystrokes / MIDI messages that the pedal will send via USB to your computer.

bank 1 is for Youtube / Vimeo (and can be used for other applications that support custom keyboard shortcuts)
- footswitch Play / Pause
  - short press will toggle between play and pause
  - long press will reset the playback rate and clear the loop
  - sends Shift+Alt+S (Shift+Alt+Q for long press)
- footswitch Loop
  - 1st time: sets start of the loop
  - 2nd time: sets end of the loop
  - 3rd time: clears loop
  - sends Shift+Alt+W (Shift+Alt+T for long press)
- footswitch Back
  - short press will jump back 5sec
  - long press will rewind the video
  - sends Shift+Alt+A (Shift+Alt+R for long press)
- footswitch Fullscreen
  - will toggle between normal screen and full screen
  - sends Shift+Alt+F (Shift+Alt+Z for long press)
- footswitch Forward
  - will jump forward 5sec
  - sends Shift+Alt+D (Shift+Alt+H for long press)
- footswitch Speed
  - will toggle between playback rates (100% -> 75% -> 50% -> 35% -> 20% and back again to 100%)
  - sends Shift+Alt+S (Shift+Alt+Q for long press)
bank 2 is for any other application like your DAW
- it will send MIDI Program Change (PC) messages on channel 16 that can be assigned to useful functions in your DAW
- Play / Pause sends 5 (55 for long press)
- Loop sends 2 (22 for long press)
- Back sends 4 (44 for long press)
- Fullscreen sends 3 (33 for long press)
- Forward sends 6 (66 for long press)
- Speed sends 1 (11 for long press)
- if you want to change them...
  - modify the Arduino code and upload it to the Arduino Micro
  - instructions where to modify the code are right at the top of that file
