-        Execute a list of FFmpeg commands.
+        Execute a sequence of FFmpeg commands and log their output.
+
+        This method iterates over a list of command attribute names, constructs the
+        appropriate log file path for each command, sets up the FFREPORT environment
+        variable to log FFmpeg output, updates the GUI with the current step, and
+        executes each FFmpeg command.
+
+        Args:
+            commands (list of str): A list of attribute names corresponding to FFmpeg
+                                    commands to be executed. Each attribute should
+                                    be a list representing the FFmpeg command and its
+                                    arguments.
+
+        Behavior:
+            - For each command in the list, the method constructs a log file path
+              where the FFmpeg output will be recorded.
+            - On Windows, the log file path is normalized and adapted to ensure compatibility
+              with FFmpeg's logging mechanism.
+            - The FFREPORT environment variable is set to point to the log file with a
+              logging level of 32.
+            - The GUI is updated to display the current step and the command being run.
+            - Each command attribute is retrieved using `getattr` and passed to the
+              `run_ffmpeg_command` method, which handles the actual execution of the FFmpeg command.
+            - If the execution of any command fails, the process is halted.
+
+        Example Usage:
+            If the class has attributes like `cmd1`, `cmd2`, etc., representing FFmpeg commands,
+            you can execute them by calling:
+                self.execute_ffmpeg_commands(['cmd1', 'cmd2'])
+
+        Logging:
+            - Logs for each command are saved in the 'logs' subdirectory of the output folder,
+              with filenames in the format '<command_name>_log.log'.
+            - The log files contain detailed information about the FFmpeg command's execution,
+              useful for debugging and auditing.
+
+        Note:
+            - Ensure that the attributes specified in the `commands` list exist and are valid
+              FFmpeg command lists.
+            - The method assumes the presence of an `output_folder` attribute, a `step_label`
+              for updating the GUI, and an `output_text` list for collecting log messages.
+            - The `run_ffmpeg_command` method should be defined to handle the actual execution
+              of the FFmpeg command.
