Extract all frames from a movie using ffmpeg
# Output a single frame from the video into an image file:
ffmpeg -i input.mov -ss 00:00:14.435 -vframes 1 out.png
# Output one image every second, named out1.png, out2.png, out3.png, etc.
# The %01d dictates that the ordinal number of each output image will be formatted using 1 digits.
ffmpeg -i input.mov -vf fps=1 out%d.png
# Output one image every minute, named out001.jpg, out002.jpg, out003.jpg, etc.
# The %02d dictates that the ordinal number of each output image will be formatted using 2 digits.
ffmpeg -i input.mov -vf fps=1/60 out%02d.jpg

YIFY's Quality Encoding

For those that want to keep the YTS going (No, IDGAF about people that don't care for YTS quality) get HandbrakeCLI https://handbrake.fr/downloads... and use the following settings:

user@user:~$HandBrakeCLI -i /file/input.mp4 -o /file/out.mp4 -E fdk_faac -B 96k -6 stereo -R 44.1 -e x264 -q 27 -x cabac=1:ref=5:analyse=0x133:me=umh:subme=9:chroma-me=1:deadzone-inter=21:deadzone-intra=11:b-adapt=2:rc-lookahead=60:vbv-maxrate=10000:vbv-bufsize=10000:qpmax=69:bframes=5:b-adapt=2:direct=auto:crf-max=51:weightp=2:merange=24:chroma-qp-offset=-1:sync-lookahead=2:psy-rd=1.00,0.15:trellis=2:min-keyint=23:partitions=all

Reason to use CLI over GTK has to do with lack of support for advanced settings for Handbrake GTK

** Don't Re-encode already shitty encodes...get good source!**

Use FFmpeg to resize and generate .mp4 & .webm videos from any source video.
/**
Scaling
- Scale can be used as is which will set the height to 560 but keep aspect ratio for width.
- Other options include setting both with & height
- Watch out for sizing errors when not divisible by 2
**/
/** MP4 1st pass **/
ffmpeg -i input.mov -vcodec libx264 -vprofile high -preset veryslow -b:v 225k -maxrate 300k -bufsize 1000k -vf scale=-1:560 -threads 2 -pass 1 -an -f mp4 /dev/null
