2 = 90CounterClockwise
3 = 90Clockwise and Vertical Flip

ffmpeg -i input.avi -filter:v scale="trunc(oh*a/2)*2:720" -c:a copy output.mkv

The -1 will tell ffmpeg to automatically choose the correct height in relation to the provided width to preserve the aspect ratio. -1 can also be used for width if you provide a given height.
One downside of scale when using libx264 is that this encoder requires even values and scale may automatically choose an odd value resulting in an error: width or height not divisible by 2. You can tell scale to choose an even value for a given height (720 in this example):

scale="trunc(oh*a/2)*2:720"

...or a given width (1280 in this example):

scale="1280:trunc(ow/a/2)*2"

SELECT PORTION OF VIdEO TO REMOVE(8SECONDS)
To select just the relevant portions of the video, I used the -ss (start/seek position) and -t (time/duration) flags, e.g.:

ffmpeg -f h264 -i input-video-file.264 -ss 180 -t 8 output-video-file.mp4

The above example takes 8 seconds of the input video starting at the 3-minute (180-second) mark.

I added a flag to specify the framerate:

ffmpeg -f h264 -r:v 7 -i input-video-file.264 -ss 180 -t 8 output-video-file.mp4

EXTRACT ALL FRAMES AS IMAGES FROM AVIDE
ffmpeg -i "Blue Angels Fly By.mp4" -vf fps=30 "Blue Angels Fly By %d.png"

RESCALING
use following commands to do rescaling for videos and images. For fixed width and height -
ffmpeg -i input.avi -vf scale="720:480" output.avi
and if you want to retain aspect ratio just give height as -1 and it will automatically resize based on the width -

ffmpeg -i input.avi -vf scale="720:-1" output.avi
If you want to scale based on input size Eg. lets say reduce the width/height yo half you can do-

ffmpeg -i input.avi -vf scale="iw/1:ih/2" output.avi
------------------------------------------------------------------------------------------

CREATE SERIES OF THUMBNAILS OUT OF AVIDEO USING I-FRAME METHOD

ffmpeg -i yosemiteA.mp4 -f image2 -vf "select='eq(pict_type,PICT_TYPE_I)'" -vsync vfr yi%03d.png

"select='eq(pict_type,PICT_TYPE_I)'": extracts I-frame image

Example Usage
Altering the frame rate (the global playback rate):
Examples:
Double a video's frame rate with butterflow -r 2x <video>.
-r, or --playback-rate, sets the global playback rate.
-r 3x would triple the frame rate, -r 4x would quadruple the frame rate, etc.
Set a video's frame rate to 60fps with butterflow -r 60 <video>.
Set a fractional frame rate: butterflow -r 23.976 <video>.
This command is the same as butterflow -r 24/1.001 <video>.
Note: In general frames will be interpolated if the frame rate is increased, otherwise they'll be dropped. The video's original rate will be used if -r is not set (an X fps input video will yield an X fps output video).
