Manual conversion

This program converts video files in more common formats. If you require other video formats, convert them manually with the following code:

    ffmpeg -i %1 -s 320x240 -r 14 -b 50 -ar 22050 -ab 56 -ac 1 %1.mov

Where:

-i Input file (%1 it's the file selected)
-s Video size* (WidthxHeight). Example: 176x96, 176x144, 320x240, 352x240, 368x288, 480x320, 552x414, 640x360, 640x480
Note: valid sizes for Cell Phone are: 128x96, 176x144, 352x288, 704x576 and 1408x1152.
-r Video frame rate (Fps). Example: 10, 12, 15, 14, 20, 24, 29
-b Video bitrate (Kb/s). Example: 30, 50, 100, 150, 200, 256, 384, 500, 512, 640, 768, 900, 1500
-ar Audio sample rate (Hz). Example: 8000, 16000, 22050, 24000, 32000, 44100, 48000
-ab Audio bitrate (Kb/s). Example: 12, 16, 32, 40, 48, 56, 64, 80, 96, 112, 128, 192, 224, 256
-ac Audio channels (1 mono, 2 stereo). Example: Use 2 if you convert in MP3
%1.xxx Output file (.xxx the format to convert!). Example: .mov, .ra, .mpg, .mp4, .mp3, .wma...


If you have installed appropriate codecs, you can convert to other formats. This is the command line syntax - to .mpg format:

    ffmpeg -i %1 -s 320x240 -sameq -b 500 -ar 22050 -ab 56 -ac 2 %1.mpg

There are other options: disabling audio, editing video, etc. We recommend that only experts attempt these.

Manual Conversion Examples

How to Disable Audio & Cut Video:

If you must edit or cut video, use the options -ss to set the start time, and -t to set the duration in seconds - ie: cut the first 10 seconds and the duration is 2:22 (142 seconds) the command line syntax is:

    ffmpeg -i %1 -s 320x240 -r 14 -b 50 -ar 22050 -ab 56 -ac 1 %1.mov -ss 10 -t 132

If you want even/or disable audio, use the options -an (in substitution of -ab and -ac):

    ffmpeg -i %1 -s 320x240 -r 14 -b 50 -ar 22050 -an %1.mov -ss 10 -t 132

How to convert video to iPhone or iPad:

Apple's website says that the technical aspects of their iPhone shows a 480x320-pixel screen. But read the find print, you will see it states: Up to 5 hours of battery life is based on H.264 1.5-Mbps video at 640-by-480 resolution combined with 128-Kbps audio.

Assuming it supports H.264 video compression, it should also support MPEG-4 compression. Using this baseline MPEG-4 option should allow you to convert video and audio without much distortion or loss of quality. MPEG-4 is easier to decode than H.264, so it requires less out of the CPU. This conversion makes better use of your computer's time and resources.

Another way to convert for iPhone:

    ffmpeg -i %1 -vcodec h264 -sameq -s 480x320 -r 29 -b 768 -ar 44100 -ab 96 -ac 2 %1.mp4


Converting video files to PSP:

ffmpeg tool does it all when converting videos to play on PSP:

Istructions step by step:

1. Convert the video to PSP format:

    ffmpeg -i %1 -f psp -s 320x240 -r 29 -b 768 -ar 24000 -ab 64 %1.mp4

1.1. Widescreen resolution of 368x208 will also work.

1.2. If "-r 29" does NOT work try "-r 14"

1.3. You MUST rename output file, ie: M4V00001.mp4, M4V00002.mp4, etc.

2. Extract the thumbail image:

    ffmpeg -y -i %1 -f image2 -ss 5 -vframes 1 -s 160x120 -an %1.thm

2.1. Rename output file, ie: M4V00001.thm, M4V00002.thm, etc.

3. Copy files in your PSP device.


Codecs and playing different video formats

Most Windows OS are not ability to play streaming web video formats, such as .flv files. You can install a separate player or convert files to a playable format. Converting files sometimes causes issues with the videos or the computer itself, so downloading and installing a proper web video player might be the way to go - such as the one available from VLC media player - It is a free, open source program that plays most video formats.

To convert files, codecs are necessary to do so, and to watch videos converted from other formats. Separate codecs much be installed/updated if you have issues with audio and video syncing up. Using Windows Media Player to play videos? Update the player's online codecs. Install these free FFDshow video codecs.
