Maybe its somewhere on the forum, but I could not find the exact information on how to convert an avi to mp4 using ffmpeg for the Instinct. I ended using this:
Command Line:
ffmpeg -y -i input.avi -b 256k -s 432x240 -vcodec mpeg4 -ab 128k -acodec aac -ac 2 -f mp4 output.mp4
-y = Overwrite output files
-i = Input file (original video file)
-b = Video bitrate (256k was OK for me)
-s = Video size (432x240 is the Instincts screen size)
-vcodec = Video codec to use (I used MPEG4 since using DIVX resulted in a crappy video...)
-ab = Audio bitrate (128k sounds great)
-acodec = Audio codec (I used aac)
-ac = Audio channels (2, in order to maintain stereo sound)
-f= force format (I forced MP4)
... and at the end you put the output file name.
I converted a Heroes episode and got nice results in overall. I got a very high pixelation on fast scenes but the rest looks pretty good. Sound is great and no sync problems. File size reduced from 350 MB to 117 MB.
This is the official download page for ffmpeg.
http://ffmpeg.org/download.htmlBut you need to download the code and compile it... UNIX stuff...
For Windows users like me:
http://ffdshow.faireal.net/mirror/ffmpeg/The first one is the latest on this list. There may be more recent files on the net...
I hope this info helps someone. I know maybe someone comes saying its already posted 200 times but, as I said, I could not find it...
By the way, Im using this version of ffmpeg:
