+In case when you have a few videos and you don't want to set up CVAT tasks one-by-one manually,
+you can use the `multi tasks` option.
+> This feature is available for videos only.
+
+Create several tasks pressing `+` button and select `Create multi tasks` on the tasks page or on the project page.

+Specify the task parameters:
+
+- In the `Name` text field, there is a template you can use for quick and simple task naming.
+
+  ![](/images/image255.jpg)
+
+  In the template you can manage the following:
+  - some_text - any text that will be entered into the template will be the same for all created tasks.
+  - {{index}} - index file in set (sets a number of a task starting from 0).
+  - {{file_name}} - name of file (sets a task name from a filename).
+
+  You can find out a prompt by hovering the mouse over the text `When forming the name, a template is used`.

+   name will be specified after it.
+1. After selecting files, file names will be shown under the `Select files` section.
+   In case of there are more than 4 files, the total number of selected files will be displayed only.
+
+   ![](/images/image258.jpg)

+
+You can face with the following errors during multi tasks creation:
+
+- If where were no video files selected, this warning will be shown.
+
+  ![](/images/image262.jpg)
+
+- If during tasks creation there was not possible to process with some videos,
+  the names of such videos will be displayed in the `Failed files` list. In this case, you can try
+  to create tasks for these videos one more time by clicking on the `Retry failed tasks` button,
+  or you can click on the `Ok` button to skip these videos.
