Step 2 Conversion Setup

Profiles

Select "User-defined" to enable yourself to customize the audio and video settings.

Otherwise, you can simply select one from the pre-defined profiles. The profiles are several different combinations of audio Bit rate, Sample rate, video Bit rate, and Frame rate, which can make the output Flash Video suitable for different network band width.

Audio Settings

    • [Enable audio]: Do not check this option if you want the created Flash Video without sound.
    • [Sample rate]: The higher sample rate is, the better audio quality you can get, but the file size of the created file would be larger.
    • [Bit rate]: The higher Bit rate is, the better audio quality you can get, but the file size of the created file would be larger.
    • [Channels]: You can choose Mono or Stereo channel.
    • [Gain]: You can adjust the audio volume by dragging the gain slider. The range is from -5.0 to 30.0db. Please note that if the gain is too high, the audio may get distortion.

Video Settings

    • [Width & Height]: The program locks the width to height ratio by default. Click the lock button to unlock it.
    • [Bit rate]: The higher Bit rate is, the better video quality you can get, but the file size of the created file would be larger.
    • [Frame rate]: The program will automatically get the Frame rate from the source video. Keep the same Frame rate is suggested. If you want to reduce the output file size and do not mind about the quality retrograding, you can lower the Frame rate.
    • [Key frame interval]: The smaller key frame interval is, the better picture fluency of Flash Video you can get, but its file size will be larger.
      The suggested key frame interval is half of the Fame rate value. For example, if the Frame rate is 24, then you'd better set the key frame interval to be 12.
    • [Zoom Mode]: There are 3 different zoom modes you can choose: LetterBox/Pan&Scan/Stretch.

Zoom Mode

  • LetterBox
    - If you adopt LetterBox mode, the picture will be shrunk to fit the target dimension while preserving the aspect ratio of source video, and black bars will be added to fill the gaps.
  • Pan & Scan
    - Only parts of the source video would be converted with Pan & Scan mode. The program will cut out some detail around the picture, which is not considered that important, to make the width or height fit.
  • Stretch
    - With Stretch mode, the whole video will be recorded at full dimension for preserving all the fine details, but the picture will lost the original aspect ratio and be literally squashed out of shape.

    Example:
    Set the same target dimension "320x240", and adopt different zoom mode for each conversion. Here is one original picture of a source video with 480x270 dimension:

    Then when the video is converted with LetterBox mode, the picture will be like this:
    Video Encoder for Adobe Flash - LetterBox

    With Pan & Scan mode:


    With Stretch mode:
