Not sure where to post this. Draft .VBS scripts for people like me who prefer to fiddle with command lines for FFMPEG and X264, to convert between formats with AVIsynth filtering. Some friends don't have codecs installed for .RM or H.264 etc, so handy to convert it for them to something they have. If this has been done already, please let me know.
How:- Copy the .VBS to the folder with the clips, edit the .VBS to set up preferred command line parameters, then double-click the .VBS. It creates a .BAT file which you can then double-click to run, or edit first.
Could create a version for IPOD output (which parameters, there are lots of combinations on the net, avisynth re-sizing necessary but how to determine in script the incoming dimensions and then calculate the right aspect ratio etc...)

How:- Copy the .VBS to the folder with the clips, edit the .VBS to set up preferred command line parameters, then double-click the .VBS. It creates a .BAT file which you can then double-click to run, or edit first.
Could create a version for IPOD output (which parameters, there are lots of combinations on the net, avisynth re-sizing necessary but how to determine in script the incoming dimensions and then calculate the right aspect ratio etc...)

' Show QP histogram.
'-vbsf bitstream filter'
' Bitstream filters available are "dump_extra", "remove_extra", "noise".
'
' FFMPEG AUDIO OPTIONS
'-ar freq'
' Set the audio sampling frequency (default = 44100 Hz).
'-ab bitrate'
' Set the audio bitrate in bit/s (default = 64k).
'-ac channels'
' Set the number of audio channels (default = 1).
'-an'
' Disable audio recording.
'-acodec codec'
' Force audio codec to codec. Use the copy special value to specify that the raw codec data must be copied as is.
'-newaudio'
' Add a new audio track to the output file. If you want to specify parameters,
' do so before -newaudio (-acodec, -ab, etc..). Mapping will be done automatically,
' if the number of output streams is equal to the number of input streams,
' else it will pick the first one that matches. You can override the mapping using -map as usual. Example:
' ffmpeg -i file.mpg -vcodec copy -acodec ac3 -ab 384k test.mpg -acodec mp2 -ab 192k -newaudio
'-alang code'
' Set the ISO 639 language code (3 letters) of the current audio stream.
'-atag fourcc/tag'
' Force audio tag/fourcc.
'-absf bitstream filter'
' Bitstream filters available are "dump_extra", "remove_extra", "noise", "mp3comp", "mp3decomp"
'
' FFMPEG ADVANCED OPTIONS
'-map input stream id[:input stream id]'
' Set stream mapping from input streams to output streams.
' Just enumerate the input streams in the order you want them in the output.
' [input stream id] sets the (input) stream to sync against.
'-map_meta_data outfile:infile'
' Set meta data information of outfile from infile.
'-debug'
' Print specific debug info.
'-benchmark'
' Add timings for benchmarking.
'-dump'
' Dump each input packet.
'-hex'
' When dumping packets, also dump the payload.
'-bitexact'
' Only use bit exact algorithms (for codec testing).
'-ps size'
' Set packet size in bits.
'-re'
' Read input at native frame rate. Mainly used to simulate a grab device.
'-loop_input'
' Loop over the input stream. Currently it works only for image streams.
' This option is used for automatic FFserver testing.
'-loop_output number_of_times'
' Repeatedly loop output for formats that support looping such as animated
' GIF (0 will loop the output infinitely).
'-threads count'
' Thread count.
'-vsync parameter'
' Video sync method.
' Video will be stretched/squeezed to match the timestamps,
' it is done by duplicating and dropping frames.
' With -map you can select from which stream the timestamps should be taken.
' You can leave either video or audio unchanged and sync the remaining stream(s) to the unchanged one.
'-async samples_per_second'
' Audio sync method. "Stretches/squeezes" the audio stream to match the timestamps, the parameter is the maximum samples per second by which the audio is changed. -async 1 is a special case where only the start of the audio stream is corrected without any later correction.
