I am looking for free software to do batch conversions of divx video files to iPhone format.

I have read the thread:

http://superuser.com/questions/5784/looking-to-convert-video-to-iphone-format

Handbrake works good for single files but it has very little customization with regards to files names and the batch functionality is not very good (or at least I can't get it to work very easily).

Can anyone recommend a good batch converter? A script for Handbrake to do a batch for all in a specific directory would be useful even.

winff would do - its a nice little front end for ffmpeg, and works on windows and linux. It also gives you the ffmpeg commands should you want to do it in command line.

i edited it with a link a couple of minutes after my initial post winff.org would be what you want – Journeyman Geek Sep 13 '09 at 7:50

Handbrake is easily automated by creating a batch script using HandBrake CLI (see the links found at the end, or just simply google for many examples).

+1 for the useful scripting. – Kelsey Sep 13 '09 at 15:42

Besides Handbrake, there is also XVID4PSP to check.
If the first one works for you, stick to it.

Perhaps videora can help you? Videora. If you are on a Mac try using ReduxEncoder.

I did a script in order to do what you are trying to do, but for a different kind of phone.

I used mencoder, which is a part of Mplayer (link). It has the advantages of being free, and able to play nearly anything you throw at it.

You should check out this question, I created it in order to centralize mencoder commands.

Here's the command for my phone :

mencoder "input.avi" -ovc lavc -oac lavc -lavcopts acodec=mp3:abitrate=128 -vop scale=400:240 -ffourcc DX50 -o "output.avi"

Someone else mentionned this command for iphones, but I haven't tested it :

mencoder "$file" -subcp cp1252 -sub-fuzziness 1 -subfont-autoscale 3 -subfont-blur 2 -subfont-outline 2 -aid 1 -vf scale=480:320:0:0:0.00:0.50,dsize=480:320,harddup -sws 2 -of lavf -lavfopts format=mp4 -ovc x264 -x264encopts bitrate=768:qcomp=0.6:qp_min=10:qp_max=51:qp_step=4:vbv_maxrate=1500:vbv_bufsize=2000:level_idc=30:dct_decimate:me=umh:me_range=16:keyint=250:keyint_min=25:nofast_pskip:global_header:nocabac:direct_pred=auto:nomixed_refs:trellis=1:nobrdo:nobime:nob_pyramid:nob_adapt:no8x8dct:noweight_b:bframes=0:threads=auto:frameref=1:subq=6 -af channels=2 -oac faac -faacopts br=128:mpeg=4:object=2:tns:raw -o /converted_"$file" .m4v

Once you have found the mplayer commands that work well with your phone, you can add them in a python script, allowing you to batch convert lots of files :
