Last year, we presented a method of producing customized outreach videos through the utilization of Chrome, OBS, Google Sheets and Loom in our blog post. This was an illustration of the capabilities of an RPA (Robotic Process Automation) product.

But the configuration of this automation was difficult, and some delicate stages in the setup process created confusion and issues for our users. Moreover, we were frequently approached with questions on how to scale this automation.

The below screenshot shows an example of a generated outreach video recorded while visiting a potential customer's website:

Sample Personalzied Video

Finally, to address these issues and fulfill the requests we received, we have developed a new flow from the ground up. It can now run smoothly on Mac, Linux, and Windows operating systems, and the setup process has been simplified significantly. Additionally, we have made it possible to run this automation at scale on our cloud platform.

In this article, we will explore how to convert this automation flow into an App that can be operated from the Robomotion Apps, enabling us to generate multiple instances of this Bot and execute them using our Cloud Run capability.


Log in to your Robomotion workspace. If you haven't registered yet, you can create your workspace from here.

We will start by importing the second version of our Personalized Video Creation flow from here. Click the Import button shown below.

Import Flow


Double-click the "Config" named node shown below.

Double-click Config

The node's editor will be shown as below:

Node Editor

This flow can run with the default inputs without changing anything, but to customize it, four inputs are required:

  1. A 30 to 60 seconds outreach video must be created and shared with a URL. (msg.video_url)
  2. A CSV file containing a list of your prospects' names, and website addresses must be created and shared with a URL. (msg.csv_url)
  3. An optional paid Loom account cookie value is required if you want to upload your generated videos into your Loom account. (msg.loom_cookie)
  4. An optional empty directory for your generated videos and CSV file. If not given, the default folder will be your Home directory. (msg.home)

In the following sections, we will discuss each of these inputs in detail.

Outreach Video

We aim to generate a customized video for your potential customers. The automation opens up your prospect's website, positions your outreach video in the bottom right corner of the screen, and records the entire session to create a video. To achieve this, you must first create your own outreach message. For instance, here is a fake outreach video as a starting point.

You can use the video URL provided with the flow by not updating the default value of msg.video_url in the opened editor window, or you can create your own video and upload it somewhere, share it publicly and use that video URL.

In this article, we will demonstrate how to accomplish this using Google Drive, but you can utilize any platform to share your video. However, please ensure that you provide a direct download link rather than a website link that opens up when accessed through a browser.

  1. Go to your Google Drive and upload your outreach video.

Google Drive

  1. Right-click the uploaded video file and click the Share link.

Google Drive

  1. Click the Restricted option and then change it to Anyone with the link.

Google Drive

  1. Click the Copy link button.

Google Drive

The link that you copied may look similar to the example below. However, the issue with this link is that it is not a direct download link. Therefore, we must generate a direct download link from this previously copied link.

Google Drive

This copied link contains your Google Drive File ID inside the URL as seen above. Copy the underlined Drive File ID and replace it with the Place Holder in the link below:

Now, this will be your direct download video URL link:

You can download the sample Video file from here and update it with your prospects.

CSV File

To execute the automation flow, you will need to provide a CSV file containing the names of your potential customers' company names and their associated website URLs in a specific format. The following example illustrates what the CSV file should look like.

CSV File

You can download the sample CSV file from here and update it with your prospects.

Then follow the same upload process described in the previous section for the Outreach Video. Upload this CSV file to Google Drive and create your direct download link.

This section is optional. If you don't have a paid Loom account or don't want to upload your generated videos to Loom, just skip this section and leave the msg.loom_cookie value with an empty string in the opened editor window.

  1. Open Chrome Browser and go to the Loom Login page and log in from your browser.


  1. Press F12 in the Chrome Browser and the Chrome Dev Tools window will be opened. Click the Application tab first, click the domain under the Cookies section left and finally find the cookie named connect.sid in the opened cookies list. Double-click the Value section and copy your Loom Cookie.

Loom Cookie

You can now write your cookie value into the msg.loom_cookie in the opened editor windows as below:

Update Cookie

Home Folder

When the flow runs, all the generated videos and the output.csv files will be written into the given home folder (msg.home) in the Config node editor. The default value for all the operating systems is the actual user's Home Directory.

You don't need to change this default, but if you like to, here are some example folders for each operating system:

For Windows, it is "C:/Users/John/Outreach"
For Linux, it is "/home/john/outreach"
For Mac, it is "/Users/john/outreach"

You can create an empty folder/directory in your file system and replace the msg.home = global.get("$Home$"); line with the full path of your created folder. Make sure your path does NOT contain a trailing "/" as in the examples above.

After replacing the msg.home value in the opened editor, it would look something like below for the Windows operating system:

msg.home = "C:/Users/John/Outreach"

Make sure your path is inside double-quotes and does NOT end with a trailing slash (/).

Run in Flow Designer

We have finished the setup and you can run your flow with your Robot connected to your workspace. If you haven't run any flows before, you can learn from our Getting Started guide.

To execute the flow, click on the Run button in the Flow Designer. Once the flow is completed, you can locate the generated files within the specified home folder that you have configured.

Flow Run


While the flow is running, you will NOT see a picture-in-picture video like in the previous version of this flow. Chrome will be opened and the recording will be done in the background.

Run in Robomotion Apps

So far, we have completed the setup and run it successfully.

This following section is actually optional and you do NOT need to follow through unless you want to scale this automation.

You also need to have Application Robots and Cloud Run minutes in your workspace to run your Bots on our hosted cloud platform. You can subscribe to a plan from Admin Console -> Subscriptions screen and also can buy Cloud Run minutes from this subscriptions page.

The Problem

The problem with this flow is, it can only be performed on a single computer, as you cannot use the computer while the desktop recording is in progress; any activity performed during the recording will be captured in the video.

Alternative options to perform this automation include setting up virtual machines (VMs) or deploying multiple Virtual Private Servers (VPS) machines. However, we have a much better solution, which is our Robomotion Apps and Cloud Run feature.

By utilizing the Robomotion Apps, you can transform any of your flows into a reusable Bot. Additionally, you can supply different input parameters from the Robomotion Apps for each execution. This enables you to provide different outreach video URLs or CSV files for this specific use case.

Follow the below steps to create your first Bot:

Update the Flow

  1. Cut the Inject (renamed as "Start") node wire to the Config. Put and connect an App In node instead.

App In

  1. Double-click the "Config" node and replace all the hard-coded string values of msg.video_url, msg.csv_url and msg.loom_cookie with equivalents.

Msg Payload

Do NOT change the msg.home value and leave it as msg.home = global.get("$Home$");

Here are the values for easy copy-paste:

// Pre-recorded outreach video
msg.video_url =;

// Prepared CSV company list
msg.csv_url =;

// Loom Cookie (OPTIONAL)
msg.loom_cookie =;

// Home Folder
msg.home = global.get("$Home$");

Publish the Flow

To create a Bot from our flow, we need first to version and publish our flow.

  1. Click the "master" button.


  1. Create a new version after clicking the "Create Version" button. Fill in the Name and the Description fields and press the "Ok" button.

Create Version

  1. Finally, publish the created flow version. This is required by the Admin Console.

Create Version

Create Bot

We will open the Admin Console application to turn our flow into an App.

  1. Click the hamburger menu at the top left corner and then click the Admin Console link.

Menu     Admin Console

  1. Now in the Admin Console, click the Bots link.

Admin Bots

  1. Click the Add Bot button and fill in the details as below.

Create Bot

3.1 Name: Outreach Video Creator

3.2 Description: Personalized video creator

3.3 Published Flow: Outreach Video Creator v2 ( this is the name of the flow you have published previously )

3.4 Flow Version: v1 ( this is the name of the version you have published previously )

3.5 Icon:

  1. Click the Advanced tab in the "Create Bot" dialog and select "2 vCPU 4 GB Memory", then click the Create button. This automation needs a minimum of two vCPUs to run.

Create Bot

You will see Bot created successfully message at the end.

  1. Click the "Setup" item from the action menu of the newly created Bot. We can use the Setup option to create a Setup screen for our Bot with a special JSON object. The format of this JSON object is like the Robomotion Forms.

Bot Setup

Just copy and paste the below JSON object into the Setup popup, save and close the window. To understand this JSON you can watch the Robomotion Forms video.

"schema": {
"type": "object",
"required": [

You can also rename each instance if you like from the action menu on the right side of the instance item.


Mac Capture Device Auto-Detect Problem

If you are using a Mac, your flow may fail at the Run node as below. This is because currently the flow can not determine the correct capture device automatically for Mac.

Troubleshot Mac

Follow these steps, to fix this problem.

  1. Find the Device Setup node and double-click to edit it.

Troubleshot Mac

  1. Find the capture device number, you are going to update.

Troubleshot Mac

  1. Open Terminal on Mac, copy-paste and run the below command
$HOME/.config/robomotion/packages/bin/Robomotion/FFmpeg/0.2.3/ffmpeg -f avfoundation -list_devices true -i ""

The output should be something like this. The numbers between brackets are the capture device numbers you can use:

Troubleshot Mac

  1. Replace the "0" in the msg.recording_input = "0"; line with the number you see in the previous output. For this example output, the capture device index number can be something like below:
msg.recording_input = "2";

or it can be

msg.recording_input = "3";
  1. Try running the flow again.

Generate Personalized Outreach Videos

· 8 min read
Faik Uygur
Co-Founder of Robomotion

Personalized videos are becoming increasingly popular as a way to stand out in the crowded email inbox. Loom, an online video messaging platform, enables users to create custom videos with a personalized touch. These videos can be included in outbound emails for a more engaging approach to customer outreach.

The below screenshot shows an example outreach video recorded while visiting a customer website:

Sample Personalzied Video

But creating a personalized video for each outreach is a difficult and time-consuming process. Robomotion can be used to auto-generate this content for you by utilizing different tools such as a video recorder, Chrome browser and Loom for uploading and sharing the content.


We will start by creating our flow in Robomotion. We will then set up a Chrome profile that keeps our session so that we won't need to automate a login page and directly use Loom. We will use OBS Studio, an open-source video recorder, and streamer. We will set up the default settings for our automation in OBS Studio. And lastly, we will set up Google Sheets for our robot to use in the automation process.

Flow setup

Log in to your workspace, and open the projects dialog by clicking the button right next to the Flow Designer logo.

Open Projects Dialog

Click the New Project button, set your project name as Chrome Setup and press Ok.

New Project

Once the project is created, press the save button.e

Save Button

Chrome User Data Directory setup

The Chrome user data directory contains profile data such as history, bookmarks, and cookies, as well as other per-installation local state. We will use the User Data Directory to save the login state to Loom so that we will not have to develop login automation for every flow run to execute.

Create the following flow by drag-and-dropping the nodes from the node palette, or by right-clicking on the empty board. You can also search the nodes by name:

Initial Flow

Below is the list of nodes used in this flow:

  • Trigger -> Inject
  • Browser -> Open Browser
  • Browser -> Open Link

Now create a folder somewhere on your file system, something like the below:


After creating this folder on your system, click the Open Browser node and fill the User Data Dir property with the full path of your folder.

User Data Dir

Click the Open Link node and fill the URL property with

Open Link

Run the flow and when the automated browser is opened, manually log in to loom. Because we are using User Data Dir, the next run of this flow will keep this login state in the given User Data Dir.

Loom Login

Go to Shiny Picture in picture Chrome Extension web page and click the Add to Chrome button.

Shiny Picture in picture

Go to I don't care about cookies Chrome Extension web page and click the Add to Chrome button.

I don't care about cookies

You can now stop the flow. This flow was only used for preparing the Chrome profile that we are going to use. The profile now can auto-login to loom. when we open the page and also have the Chrome extensions installed that we need.

Stop Flow

Outreach videos folder setup

Create a folder named Outreach on your system, and two more folders named Videos and Uploads under the Outreach folder.



Folder names are case-sensitive, so Outreach, Videos and Uploads all have capital first letter.


OBS Studio setup

We are going to be using an open-source video recorder, OBS Studio to record the video we are going to be uploading to the Loom website.

OBS Studio

Go to the OBS Studio website. Download and install OBS Studio. Start the OBS Studio application.

On start, if you see an optimization popup, select Optimize just for recording and press Next for the initial setup to finish and click Apply Settings at the end.


Some systems may not bring this popup.

OBS setup

Open File -> Settings dialog. From the General tab, check the Minimize to system tray when started.


From the Output tab,

Output Format

  • Change the Recording Format to mp4
  • Change the Recording Path to your full Outreach/Videos folder path
  • Change the Recording Quality to "Same as stream"
  • Change the Streaming Encoder Preset to ultrafast (low CPU usage, lowest quality)

You have to set the Recording Path to what you have created on your system and not what is shown in the screenshot.


Encoder affects the machine performance, so we are selecting the lowest possible. You can later experiment with the quality.

From the Advanced tab, uncheck the Show active outputs warning on exit.

Output Format

Click Apply and Ok to close the Settings dialog.

We will only need the recorder to record Desktop Audio, so we will disable the Mic/Aux. Click the speaker button right next to the Mic source.

Mute Mic

Now we are going to add a video source for the OBS recorder. Click the plus button in the Sources panel below.

Add Video Source

Select Screen Capture or Display Capture, give any name to your capture source and press Ok. You should see something similar that looks like the below screenshot. Yours may differ but you should start seeing a mirror of your Desktop in the OBS Studio.

Screen Capture Source

Close the OBS Studio application with Alt + F4 or from the File menu by selecting Exit.

Google Sheets setup

Open this template Google Sheets document and create a copy for your self and update what is inside this list with your outbound reach list.

Template Document

For the robot to read and update this new document you have created, the robot has to be authorized and have a Google Sheets authorization token.

You have to follow two documents for this:

For the second document, you only need to create a Vault and add your OAuth2 credential from the first step.

Outreach video setup

You have to have an Outreach video for your customers. You can use Loom or even OBS Studio to create one for yourself. 30 seconds would be ideal. Here is a fake outreach video that you can use for your experiments.

Record a 30 seconds video and upload it to Youtube as an Unlisted video.

In your video try to have 5-6 seconds that you do nothing and then your message should start.


Here is the flow that we are going to run after all this setup.

Click the Import icon at the top-right to be able to edit and save this flow in your workspace.

Import Template

After importing the flow, click the Config node's Edit menu item.

Config Edit

Update the links and paths in this editor with your own links.


Only change what is between the double quotes and nothing else.

Update Config

  • Change outreach_doc line with your own Outreach Google Sheets link
  • Change outreach_video line with your own Outreach video you have uploaded to Youtube
  • Change videos_path line with your full path of the Outreach/Videos folder on your system
  • Change uploads_path line with your full path of the Outreach/Uploads folder on your system
  • Change chrome_path line with your full path of the created Chrome Profile folder on your system
  • Change start_delay and stop_delay with experimentation.

Start Delay is a delay before recording starts, stop_delay is how many seconds after recording started should the flow stop recording. Every system will perform differently so with delays you can finetune the recorded video.

Click the Open Spreadsheet node and select the Vault and Vault Item property of the OAuth token you have added to the Vault.

Open Spreadsheet Credentials


We have created a Youtube video that follows this blog post.
