I am sure someone can find a better way to accomplish this, but here is a script I cooked up for monitoring the progress of handbrakes watch folder. Please forgive how crude it is, but I am still new to linux and I am not a programmer. The script itself is quite small I just included documentation to at least attempt to explain what I have this script doing.
#!/bin/bash
#
# A simple loop to display what file handbrake is working on and what the current status is.

#Example line:
#[autovideoconverter] Starting conversion of '/watch/Hercules (1997).mkv' (935bbed22b281c68d6e1840256fede3f) using preset 'Fast 480p30'...
#
#Find the last line in the log that contains the word "Starting"
#Set AWK's Field seperator to a single quote and print fields 2 and 4 to extract the movie title and preset
#Set AWK's Field seperator to a "/" and print the 3rd field to remove the path before the movie title
#Tail the log and print the last line to provide status.
#Final output:
#Hercules (1997).mkv Fast 480p30
#Encoding: 99.65 % (152.25 fps, avg 121.85 fps, ETA 00h00m04s)

#Encoding: 99.86 % (126.57 fps, avg 121.85 fps, ETA 00h00m02s)
#Encoding: 99.97 % (122.81 fps, avg 121.85 fps, ETA 00h00m01s)
#Encoding: 99.97 % (122.81 fps, avg 121.85 fps, ETA 00h00m01s)

#Last line will be encoding status or one of the below
#Change detected in watch folder '/watch'.
#Processing watch folder '/watch'...
#Waiting 5 seconds before processing '/watch/Hercules (1997).mkv'...
#Skipping '/watch/Hercules (1997).mkv': currently being copied.

#1 title(s) to process.
#Conversion ended successfully.
#Removed /watch/Hercules (1997).mkv'.
