winff - predefinições para vídeos h264

How To Make Presets    

How to Make Presets For WinFF

Making presets for WinFF is not difficult, it's learning the ffmpeg command line. All in all the ffmpeg command line really isn't that complicated considering what's being done.
So, say we wanted to create h264 preset.
The first thing to do is some googling for the h264 codecs and specification. I found that h264 requires "aac" audio codec and the video codec for ffmpeg is appropriately named "h264" (not always the case). H264 is also a mp4 file format so the extension (and also the container for ffmpeg) is "mp4"
To create the preset for it:
open WinFF
go to the filemenu and select edit presets and the preset editor will appear:


Enter the following for the name,label, command line, and extension:
name: h264
label: h264
command line: -acodec aac -vcodec h264
output file extension: mp4

Click "Add/Update"
Click OK to add the preset
Click SAVE to save the presets and return to winff

Try out your new Preset ;)
also remember different codecs need different bitrates, frame rates, etc...

is anyone interested in a high quality, low size preset? it is appropriate for mobile devices and extremely low powered computers. it is an xvid avi with high quality mp3 audio. the preset is below.
-vcodec xvid -vtag dx50 -s 640x480 -aspect 4:3 -maxrate 3000k -b 1050k -qmin 3 -qmax 5 -bufsize 300000 -bf 1 -i_qoffset 150 -b_qoffset 150 -g 300 -acodec mp3 -ar 44100 -ab 320k -ac 2
