How to convert Gif to image strips (or any format) (ffmpeg)
Quickstart @ 1:05; I'll be using ffmpeg:
https://www.ffmpeg.org/
Is ffmpeg safe to use? Well you probably already use it:
https://trac.ffmpeg.org/wiki/Projects
Why am I using ffmpeg? Cause it's the cleanest and fastest method.
Commands used:
(change gif into .png format. Or use: .jpg, .tif, etc as desired)
ffmpeg -i input.gif %d.png
(changing the .png image strips back to a gif)
ffmpeg -i %d.png output.gif
Where input is the original filename and output is the filename you will need to makeup and assign to the thing you are creating.
If you don't see file extensions automatically you need to enable them:
(On Windows) Search: folder options --view --- find "hide extensions of known types" and uncheck it, apply
(use google if you have problems with this)
If you want to specify a specific image filename output you can read how to do that here:
https://en.wikibooks.org/wiki/FFMPEG_...
tl:dr; you can do a name with
namemyfilehere%d.png
as your output.png
Other commands:
Some cool filters (scale and unsharp):
ffmpeg %d.png -vf "scale=3840:-1,unsharp=lx=13:ly=13:la=1.0" output.png
In the above case we are applying them to a single png and outputting a new single png. If I list the command as just input or just output this assumes you will apply the proper extension you want on your own.
For scale:
scale=3840:-1
This upscales the original image size to 3840 in width and the -1 specified the height to be whatever uniform scale matches that value. You can specify something specific by replacing -1 though.
i.e. 3840:2160
Unsharpen is a blur filter negative values and sharpener when positive:
unsharp=lx=13:ly=13:la=1.0
Those are l's not ones so please be careful when inputting. Here we specify the x values to 13 and the y values to 13 and we use a multiplier of 1.0.
So you can change those numbered valued and experiment:
i.e.
unsharp=lx=6:ly=6:la=2.9
or get rid of the multiplier:
unsharp=lx=3:ly=3
If you are using these filters individually use the format of
ffmpeg -i input -filter "unsharp=lx=13:ly=13:la=2.9" output
Will cover ffmpeg in more detail in a future video, and how to compliment with a video editor.
If you needed ur gif as a video format you can just assign the video extension on your output. This might not play in some players, it'll play fine in ffplay though and when uploaded somewhere. You can try specifying an audio codec with:
ffmpeg -i input -c:v libx264 -crf 20 -pix_fmt yuv422p10le output.mkv
Anyways you can check out tutorial video 3 for more information on how to do stuff like this, or search online or wait till my next video.
