The Apple iPhone is probably the hottest piece of technology for 2007. The iPhone is a great little video player, supporting H.264 video playback (as well as MPEG-4 SP). This guide shows you how to convert your video files to an iPhone compatible video file using the freeware Videora iPhone Converter.

A version of this guide dealing with the very similar Videora Apple TV Converter is available here.

Software you'll need (all freeware):


This guide is divided into two section, you only need to follow one of the sections, not both. The first section shows you the easiest way to use Videora iPhone Converter, using the built in VideoWizard tool, making conversion an almost one-click affair.

The second section goes into more detail and is intended for those that want to tweak the settings a bit, want to find out how to use the batch conversion/queuing feature.

Time to choose:

For the easy VideoWizard method, go on to the next page

For the slightly more complex but a method with more options and functions, skip to page 3



Method 1: Using the VideoWizard

Videora iPhone Converter comes with a function called the VideoWizard, which makes conversion so easy that a guide is almost not needed. Almost.

Start Videora iPhone Converter and click on the "Settings" button at the top.

Videora iPhone Converter: Settings


Click on the "Devices" tab and select "iPhone" under "Device Settings". Here, the output location of your converted iPhone video files will be listed - you should make a note of this directory, or change it to another directory. Press the "Save Device Settings" button to save these changes. If you do decide to change it, make sure that the directories exist, otherwise Videora will fail when you try to convert the video.

Videora iPhone Converter: Devices Settings


Click on the "Convert" button at the top.

Videora iPhone Converter: Convert


From the bottom, click on the "Select File" button to load in your original video file (the one that you want to convert to iPhone format).

Videora iPhone Converter: Select File


Click on the "Set Title" tab to change the title of this video file if you wish.

Videora iPhone Converter: Set Title


Back to the wizard, the video settings slider bars should now be shown. These sliders determine the encoding quality, and hence file size and encoding speed. The "Conversion Speed", "Output Video Quality" levels and the "Estimated File Size" is shown at the bottom.

Videora iPhone Converter: Video Settings


As an example, the file I used was an XviD encode that was 4.03 MB in size. I kept the "Video Format" at "New" ("New" is H.264, "Old" is MPEG-4), I applied a "High" video quality setting, with the "Enhance Quality" option set to "On", and with audio quality left at "High" - the estimate file size becomes 3 MB. Generally, because the iPhone uses H.264, is it about 80% efficient than DivX or XviD, so to get the same quality file from an DivX/XviD source, try to keep the file size at about 80% of the original. When you are happy with the video settings, press the "Next" button to continue.

The "Start Converting" button should now show up at the bottom, press it to start the conversion process.

Videora iPhone Converter: Start Converting


Conversion should begin and after a while, depending on the length of your video, the iPhone video file should now be created in the output directories that were set earlier. If you want to playback these H.264/MP4 files on your computer, you can refer to our H.264 Playback Guide, or if you don't mind using a codec pack, use these simple instruction instead.

Videora iPhone Converter: Conversion Progress


The next page deals with a more complex method for using Videora iPhone Converter, which gives you more options and functions (like queued encodings), but it's not needed if you've already followed this section. So in this case, we're done :)



Method 2: Full Guide

So you have chosen the more advanced method. Let's go.

Start Videora iPhone Converter and click on the "Settings" button at the top.

Videora iPhone Converter: Settings


Under "Encoding Profiles", listed are several profiles that you can select for encoding - each profile has a pre-defined set of settings (eg. resolution, bit-rate, and encoding options). The iPhone supports both H.264 video and MPEG-4 (Simple Profile) video - H.264 is the new codec which is more efficient than MPEG-4 SP, and you should use H.264 whenever you can. In addition to editing an existing profile, you can also create your own.

To create your own profile (which is optional, so if you don't mind using an existing profile, skip to the next page), click on the "New Profile" button.

In the "General" section, you can specify a title for your profile, and select an encoder. For best quality, select "iPhone - 2-Pass - FFmpeg MINB", this will activate 2-pass encoding which doubles the encoding time, but also improves quality. You can also set a default starting position and encoding duration, if you don't wish to encode the entire video.

Videora iPhone Converter: Add Profile - General


Now go to the "Video" section. Here is where you can configure the video settings for this profile. Let's go through the options:

Videora iPhone Converter: Add Profile - General


  • Video Codec: Select H.264 for MPEG-4 SP as your video codec.
  • Profile: For iPhone video, only one profile is available for each codec (Simple Profile for MPEG-4 and Baseline Profile for H.264).
  • Level: The "Level" determines the maximum resolution that is supported (and taking into account the supported resolutions of the device/encoder). Level 2.1 and 3 are available to select for H.264, 2.1 limits the resolution to 480x320, while Level 3 limits the resolution to 640x480
  • Bitrate Mode: You can use ABR (Average BitRate) mode or "Automated 2-Pass"
  • Bitrate (kbps): You can select a bitrate to use for your video - the higher the bitrate, the larger the file size (you can use a bitrate calculator to work out the file size, or do it manually - 1 MB/s => 1024 KB/s => 8192 kbps). The bitrate is also dependent on the video resolution - 768 kbps should give you acceptable (at least when viewed on the iPhone) quality video for H.264 @ 480x320.
  • Resolution: You should keep all the settings at "Original", unless you want to resize the video.
  • AutoResize: Keep this enabled, this will automatically resize your video. You can set a maximum resolution (based on your "Level" selection earlier).
  • AutoFramerate: Keep this enabled

Click on the "General 2" tab. More options are available:

Videora iPhone Converter: Add Profile - General 2


  • Crop: You can use these settings to crop the video (eg. use it to remove black borders around the video)
  • Padding: The reverse of cropping, add a border around the video
  • AviSynth: Enables AviSynth processing. Leave it disabled unless you know what you are doing.
  • Additional CLI Parameters: You can add additional CLI commands for ffmpeg here ... if you don't know what this means, leave it blank.

Click on the "Advanced 1" tab. More options are available:

Videora iPhone Converter: Add Profile - Advanced 1


  • Rate Control - Buffer Size: Specify the playback buffer size - too large and the video takes longer to load, to low and the video might stutter.
  • Rate Control - Minimum Bitrate: Usually keep this at 0
  • Rate Control - Maximum Bitrate: Specifies the maximum bitrate allowed in the video buffer
  • Keyframe Interval: Usually set this to 10 times the framerate of the video (keyframe every 10 seconds)
  • Number of Threads: Number of CPU threads to use for encoding

Click on the "Advanced 3" tab. Only one option here, and that is to enable CABAC. Enabling it will improve quality, at the expense of encoding speed and decoding speed.

Click on the "Audio" button at the top, here you can configure the audio options:

Videora iPhone Converter: Add Profile - Audio


  • Codec: Only one option here, and that's AAC-LC (low complexity)
  • Mode: Again, only one option, ABR
  • Bitrate (kbps): You can select the bitrate. AAC-LC is more efficient than MP3, so 128 kbps should equate to a 160 kbps MP3 to give you great quality
  • Channels: Stereo, Mono or Original
  • Sample Rate (Hz): Keep this at original
  • Volume: Increase/decrease the audio volume if you wish

Press "OK" to save your profile.



Click on the "Devices" tab and select "iPhone" under "Device Settings". Here, the output location of your converted iPhone video files will be listed - you should make a note of this directory, or change it to another directory. Press the "Save Device Settings" button to save these changes. If you do decide to change it, make sure that the directories exist, otherwise Videora will fail when you try to convert the video.

Videora iPhone Converter: Devices Settings


Click on the "Convert" button at the top.

Videora iPhone Converter: Convert


Click on the "Current Conversion" tab. Click on the "Convert Video" button and load in your original video file (the one that you want to convert to iPhone format).

Videora iPhone Converter: Convert Video


You can change the title of the video, and select an encoding profile to use (for more on profiles, see the previous page).

Videora iPhone Converter: New Video to Convert


Click on the "Start" button just underneath the above ("New Video to Convert") section to start the encoding. On the left hand side, you can change the priority of the encoding process, depending on if you have other software running or not. While your video is encoding, you can click on the "Convert Video" button again to load in other video you wish to convert, select a title/profile as above, and then click "Start" to add the video to the encoding queue. You can click on the "Shutdown when complete" to shutdown Windows when all the processes complete.

If you want to playback these H.264/MP4 files on your computer, you can refer to our H.264 Playback Guide, or if you don't mind using a codec pack, use these simple instruction instead.

We're done :)
