To create a first simple encoding workflow, right click on the job canvas, choose 'insert processor', choose category(Monitor) and select 'Folder'. Again with 'Encoders'category then 'H264“. A last one in 'Delivery'category and 'Folder”.
Link them together, left mouse click on output's node(blue square on right side of node), hold button and release it on next node : The 3 processor nodes are now connected.
Set your watch path in Monitor Node, configure your H264 encoder Processor and choose a destination folder in Delivery Node. The workflow is ready. Start the workflow with a right click on workflow's name(workflow manager window) then start. Drag a video file in your watch folder and wait for the encoding to complete.
You can submit manually a file (even if your workflow is disabled) by right-click on monitor node and choose 'Submit file(s) to folder'.
A variable can be used to “fetch” a file's information(for example), keep it in memory during all the workflow and used it when it is necessary. Many internal variables are stored from the beginning of each workflow like file's name (%s_original_name) or video file's properties (duration, frame rate,etc). It is possible to create one's own variable, use 'Populated Variable'node to create the new variable.

After importing the workflow, select it in your workflow list and right click→ submit file at the first node. It will copy the file you submitted to c:\temp (if the folder exists).
This workflow shows how to use user variables and build a path from 2 variables: The first processor “Populate Variables” is used to set the value of these 2 variables: %s_test_variable_1% and %s_test_variable_2%.
In the deliver to folder processor, the actual folder for delivery looks like this:
Which at workflow runtime will actually be translated to this:
Please play with the values, set different drive letter and folder names for experimenting.
Detailed Explanation about User Variables:

This workflow shows whats the difference between a variable and a STATIC.
In difference to user “variables”, once created and set to a value, STATICS have always the same value in every workflow, job and split. The value can only be changed by an administrator using the ffastrans UI. A job cannot change the value of a STATIC. In other words, we talk about a global (or domain) variable here.
How to create a STATIC:
1) Left Click the header of a processor (does not have to be Populate variables, could by any processor)
2) left click one of the > Symbols
3) Rickt click here and select → New
4) Select the type “static” instead of variable
5) Enter a name for this global STATIC variable. Remember, this value is always the same in each and every workflow that uses this STATIC.
6) Select the type (advanced users can use something different than string)
7) Enter a value for the static. Note again that this value cannot be changed by a job

This workflow is demonstrating how to catch and resolve errors.
It first tries to deliver the input file to a share that actually does not exist. (wait a while, it will retry 100 times). When it fails, it will deliver to a fallback location. After that, we use a hold node with “synchronize” option in order to be able to go on with the main branch.
I guess this is a little known but very powerful feature of FFAStrans workflows. Right click the input connector of a processor to select if the processor is executed on success, error or in any case.
