Systematically loop through a file list and use Handbrake and exiftool to re-render video files.
I wrote this script because I wanted an easy way to grab a list of video files and rerender it using my favorite video render app Handbrake. This works great to get all those home videos from all those cameras you've had over the pass and get them into something usable like an Apple TV format. I prefered making the list of files for this script manual rather than doing it in the script because I often wanted to review the list before lengthy render started.
This script requires two pieces of free software: Handbrake and exiftool Handbrake: https://handbrake.fr exiftool: http://www.sno.phy.queensu.ca/~phil/exiftool/
I just installed Handbrake, then dropped this handbrake CLI binary and the exiftool binary into the /usr/local/bin directory (or just anywhere your env path will find them).
Working on reducing the size of some videos on my NAS box now that my cell phone is producing 40Mbit/s rate 4k video files. When I applied this script, I found that HandBrake doesn't try to figure out your camera's orientation.
Also I noticed I had so many of the "live" video clips being sucked in from Apple's live photo capture mode. I simply solved this by creating a "duration_threshold" option and if you set it to 4 (4 seconds) it will take a look at the metadata of that video and pop it out of the list if it's less than 4 seconds. This is only tested on our current iPhones.
$ ./videoConverter.py -h
** Encoding Video Files **
[2015.08.12] 00:44:28
Usage: videoConverter.py [options]
Options:
-h, --help show this help message and exit
-i INPUT, --input=INPUT
Input folder or a text file with a list of files.
-o OUTPUT, --output=OUTPUT
Output folder
-p VIDEO_OPTIONS, --video_options=VIDEO_OPTIONS
Video Options, Default: -Z "High Profile"
-v, --verbose Verbose
-t, --trace Print what will happen but don't actually do it.
-l LOG, --log=LOG Log file. Default current directory as
handbrake_[timestamp].log
--miniDV Overrides any video parameters to use the special
miniDV one I created
--AppleTV2 Overrides any video parameters to use the AppleTV 2
preset (720p)
-d, --dir_structure Directory structure at output point from input point.
-x, --overwrite Overwrites output file if it exists. Default not to.
--add_date Add time stamp to beginning of the file's name.
--add_shot_date Add time stamp to beginning of the file's name from
"Shot Data" exif info.
--rotate Look for rotation metatdata and apply rotation command
to handbrake cmd line when needed.
--duration_threshold Weed out those videos in the list that have fewer than
seconds specified with this option.
In bo 58F4 th of these examples I use the -t option (for "trace run"). This way you can see if things like the "--add_date" feature works for your render before it starts. Simply remove it when your ready to really render the files.
find /Volumes/data/capture/Canon_M41_Capture/2015 -iname "*.mts" > list.txt && cat list.txt
./videoConverter.py --AppleTV2 --add_date -i list.txt -o /Volumes/data/Video/Canon_M41_Converted/2015_mts -tHere is an example of converting my MiniDV video.
find /Volumes/data/Capture -iname "*.mov" > list.txt && cat list.txt
./videoConverter.py --miniDV --add_shot_date -i list.txt -o /Volumes/data/rendered/Sony -tI use exiftool in this script to root out the "shot date" if I can. I really wanted a way to easily tell the dates of the video files I was using without having to look at metadata all the time. Plus it was much easier to organize video from different sources this way. It doesn't always work, it depends on the orginal footage. Most digital capture from MiniDV tape and forward probably has it unless something stripped it out.
exiftool -"ShotDate" tape_001\ 01.movShot Date : 2001:02:03 13:00:31
(Note: For larger than 4G files you need the largefilessupport option on.) exiftool -api largefilesupport=1 -r -"ShotDate" tape_001
