It can also be used to extract streams from files. FFMpeg download is also used for encoding videos with various compression codecs. This is a conversion application, which is used to convert an input it to another format.
It compiles for most platforms, including Windows, Linux, and Mac. I got the command line for the app reliable by exhaustive testing of options, not from the reference material.FFMpeg is a free, open-source, cross-platform, command-line video encoding application. I note with some humour that the entire "ffmpeg" project is run like many other Unix based projects, a wide collection of different developers doing all sorts of things and often with very good code but the documentation is all over the place like a mad woman's chyte, various bits of it are out of date or simply wrong and it is generally hard to find.
The batch file that the app creates "latest.bat" remains in the target directory and can be edited manually to re-run the process. I aim at MP4 and have few others but I tested it with some old AVI footage and it seems to work OK and you get respectable size reductions and quality with a little fiddling. With the MP4 footage I have taken recently in 4k and 1080 the results are very good and highly adjustable in terms of size and quality.
ffmpeg.exe must be in the same directory so the app will start and you also need to place ffplay.exe in the same directory so that the video is run once the processing is finished. You will need to download the ffmpeg at and as this is a 64 bit version you will need to download the 64 bit version. This version uses the codec h264 which is the most commonly used at the moment, it does have the option to run the h265 codec but I confess I have not fully decyphered its reference material and it barely performs any better than the h264 codec. I have slightly changed the way it works, it now creates a batch file to run "ffmpeg.exe" and when that is finished it will run the processed video in "ffplay.exe". This is version 2 of ffmprun and it has a wider range of options.
