 |`AUTOMATED_CONVERSION_NON_VIDEO_FILE_EXTENSIONS`| Space-separated list of file extensions to be considered as not being videos.  Most non-video files are properly rejected by HandBrake. However, some files, like images, are convertible by HandBrake even if they are not video files. | `jpg jpeg bmp png gif txt nfo` |
 |`AUTOMATED_CONVERSION_OUTPUT_DIR`| Root directory, inside the container, where converted videos should be written.  **NOTE**: Make sure a volume mapping for this directory is defined when creating the container. | `/output` |
 |`AUTOMATED_CONVERSION_OUTPUT_SUBDIR`| Subdirectory of the output folder into which converted videos should be written.  By default, this variable is not set, meaning that videos are saved directly into `/output/`.  If `Home/Movies` is set, converted videos will be written to `/output/Home/Movies`.  Use the special value `SAME_AS_SRC` to use the same subfolder as the source.  For example, if the video source file is `/watch/Movies/mymovie.mkv`, the converted video will be written to `/output/Movies/`. | (no value) |
+|`AUTOMATED_CONVERSION_OUTPUT_TEMP`| If unset, Handbrake will create a temp folder .XXXXXX inside /output directory. When set to specific path **ON THE HOST**, temporary files will get written inside (in a subdir .XXXXXX) before being moved to /output. | `(no value)` |
 |`AUTOMATED_CONVERSION_OVERWRITE_OUTPUT`| Setting this to `1` allows the final destination file to be overwritten if it already exists. | `0` |
 |`AUTOMATED_CONVERSION_SOURCE_STABLE_TIME`| Time (in seconds) during which properties (e.g. size, time, etc) of a video file in the watch folder need to remain the same.  This is to avoid processing a file that is being copied. | `5` |
 |`AUTOMATED_CONVERSION_SOURCE_MIN_DURATION`| Minimum title duration (in seconds).  Shorter titles will be ignored.  This applies only to video disc sources (ISO file, `VIDEO_TS` folder or `BDMV` folder). | `10` |
