Movie Formats Selecting Guide

BB FlashBack stores its movies in FlashBack (FBR) format. If you want non-FlashBack users to be able to watch your movie, you'll need to export it to a standard format. BB FlashBack exports to QuickTime, Flash, MPEG4, AVI, Windows Media Video (WMV), and Executable (EXE).

The best format to choose depends on the end purpose and audience of your movie. Here is a quick guide:

It needs to include 'interactive' objects like buttons and 'click to continue' textboxes:
Then you'll need to export to Flash (SWF) or EXE formats. Only these formats are capable of interactivity. QuickTime, AVI and WMV are not interactive - they just contain movies.

It will be embedded on a webpage
You'll need to export to QuickTime, WMV or Flash formats. All of these can be embedded in webpages.

It needs to play on Windows, Mac OS X and Linux
Flash is probably the best choice. If you only require Windows and Mac OS X, then Flash, MPEG4 and QuickTime are the best choices.

It needs to play back on mobile devices like an iPhone
MPEG4 format can be played back on iDevices and Android phones.

I need as small a file as I can get without reducing quality to an unacceptable level
There's no one format that will give the smallest file for all movies. If the movie is mainly of 'normal' applications like MS Office, EXE may give good results. If there is more motion in your movie, experiment with QuickTime and WMV. Exporting to AVI with codecs like XDiv and DivX can give good results, but these need to be installed on the PC that is playing the movie back also.

I'll be producing a DVD from it
BB FlashBack can't export it in the MPEG2 format which is used by DVDs. You will need to use 3rd party software to produce the DVD, so exporting to AVI may be best. Virtually all movie editing and creation software will work with AVI format.

Video Formats Choosing

Digital video can have a dramatic impact upon the user. It can reflect information that is difficult to describe in words alone, and can be used within an interactive learning process. This document contains guidelines to best practice when manipulating video. When considering the recording of digital video, the digitiser should be aware of the influence of file format, bit-depth, bit-rate and frame size upon the quality of the resulting video.

Digital video consists of a series of images played in rapid succession to create the illusion of movement. It is commonly accompanied by an audio track. Unlike graphics and sound that are relatively small in size, video data can be hundreds of megabytes, or even gigabytes, in size.

The visual and audio information are individually stored within a digital 'wrapper' an umbrella structure consisting of the video and audio data, as well as information to playback and resynchronise the data.

The provision of video data for an Internet-based audience places specific restrictions upon the content. Quality of the video output is dependent upon three factors:
  • Frame size - the height and width of the video window according to the number of pixels. Higher resolutions produce an equivalent increase in file size and require a greater amount of bandwidth to download.
  • Frame rate - The number of frames per second. Video encoded at a low frame rate (particularly below 15 frames per second) will appear jerky and unprofessional to the eye.
  • Bit Depth - determines the number of colours that will be used to view the movie. The balance between image quality and file size should be considered.

Information about 3GP and 3G2 Video Formats

3GP (3GPP file format) is a multimedia container format defined by the Third Generation Partnership Project (3GPP) for 3G UMTS multimedia services. It is used on 3G mobile phones but can also be played on some 2G and 4G phones.
3G2 (3GPP2 file format) is a multimedia container format defined by the 3GPP2 for 3G CDMA2000 multimedia services. It is very similar to the 3GP file format, but has some extensions and limitations in comparison to 3GP.
3GP is defined in the ETSI 3GPP technical specification.3GP is a required file format for video and associated speech/audio media types and timed text in ETSI 3GPP technical specifications for IP Multimedia Subsystem (IMS), Multimedia Messaging Service (MMS), Multimedia Broadcast/Multicast Service (MBMS) and Transparent end-to-end Packet-switched Streaming Service (PSS).

Methods to Play WAV Videos on iPhone

So you have a WAV file that you'd like to play on the go, but you don't know if your iPhone will support the file. There is a way, but it isn't as conventional as you might think. If you'd like to learn about playing WAV files on your iPhone then this is the article for you.

Intro to the WAV File Format

WAV is a file format for audio files within the Windows operating system. There are ways to make the file play within the Macintosh and Linux operating systems, but for the most part the file is more common within Windows. WAV stands for Waveform Audio File Format and is actually short for WAVE. This file format is typically used for uncompressed and raw audio. The equivalent to the WAV file format on a Macintosh computer is the AIFF format commonly used within the program iTunes.

What File Formats does the iPhone support?

iPhone
The iPhone uses a program known as iTunes to manage the songs on it. It typically plays music in the MP3, AIFF, and AAC formats. These are the only audio formats that the iTunes program will allow to be put on the iPhone.

Method #1: Play the WAV File as it is.

The iPhone will not play WAV files natively, but when Apple released the 1.11 update, some support for this audio format was added to the iPhone's firmware. In order to play WAV files, they must be attached to an email that the iPhone downloads. This is much the same way as the iPhone opens a Powerpoint or Word document. You have to email it to yourself, or have it emailed to you. Either way, the iPhone has to have your email set up to be downloaded through the mail application that comes with the iPhone. You can set up your email accounts with the mail application by opening "Settings > Mails, Contacts, Calendars > Add Account." After tapping on "Add Account," you simply select your email provider, enter in your username and password, and click "Save." The iPhone will then start downloading emails from that service provider. When it downloads the email that contains the WAV file as an attachment that you'd like play, it will have the attachment listed at the bottom of the email. You need only tap it once, and it will download and play the WAV file within the email.

Method #2: Convert the WAV File with iTunes.

Import your WAV file into iTunes by clicking on "File > Add File to Library." Then you find that song in the library and click on it once. After that, click on "Advanced > Create AAC Version." This will convert your WAV file to the AAC file format. When it is finished, you will see two copies of your song. Delete the WAV version, and you can add the AAC version of your song (which is an exact duplicate, nothing will have changed but the format it is in) to your iPhone, by dragging it to your iPhone on the left side of the screen. You will then be able to play your WAV file by opening the music player on your iPhone and finding the title of your WAV file. It will play the same, but it is now an AAC file, this is an audio format the iPhone natively supports.
