Mpeg

MPEG, Moving Picture Experts Group

To generate a MPEG (*.mpeg, *.mpg) file, it is necessary to set the output format properly. For that open the "Profile Settings" dialog window (or make use of the "Properties" window). In the Main section select "MPEG, Moving Picture Experts Group" from the "Output Format" list:

 

 

 

Video encoding parameters.

 

Go to the Video section. The following parameters are available here:

 

  • Codec - the codec that will be used for compression of the video stream. This parameter can take one of the following values:

 

    1. MPEG - 1.

    2. MPEG - 2.

 

  • Bitrate - the number of bits used for representation of one second of the encoded video stream. The higher its value, the larger the produced file size and the higher the produced file quality. We guess the optimal value can be found in an experimental way only. However, it is necessary to remember that the ratio between the produced file size and quality also depends on the selected frame rate and frame size.

 

  • Motion search precision - the precision of the motion vector search. This parameter affects the ratio between the produced file quality and the time taken for editing. It can take one of the following values:

 

    1. Lowest Quality (very fast).

    2. Low Quality (fast).

    3. Normal (normal) - recommended.

    4. High Quality (slow).

    5. Highest Quality (very slow).

 

  • Search Type - the type of the motion vector search. This parameter can take one of the following values:

 

    1. Estimate Search - if selected, the algorithms of approximate search will be used, which will allow to save time. Error probability is not large at that, therefore we recommend to use this search type in most cases.

    2. Full Search - if selected, the algorithm of exhaustive search will be used, which will allow to detect the motion vector with 100% precision. In this case error probability is equal to zero, but the search will take more time.

 

Depending on the selected codec, the following parameters may be available:

 

  • Encoding mode - the encoding mode. This parameter can take one of the following values:

 

    1. Non-interlace - recommended.

    2. Interlace.

    3. Top Field.

    4. Bottom Field.

 

  • Video format - the video format. This parameter can take one of the following values:

 

    1. Component.

    2. PAL.

    3. NTSC - recommended.

    4. SECAM.

    5. MAC.

    6. Unspecified.

 

  • Ouptut YUV - the output YUV format. This parameter can take one of the following values:

 

    1. YCbCr - recommended.

    2. CCIR601.

 

  • Quantization matrix - the quantization matrix. This parameter can take one of the following values:

 

    1. Default - recommended.

    2. Mpeg Standard.

    3. CG/Animation.

 

  • YUV format - the YUV format. This parameter can take one of the following values:

 

    1. 4.2.0 - recommended.

    2. 4.2.2.

    3. 4.4.4.

 

  • DC component precision - the number of bits used for encoding of a video unit. This parameter can take one of the following values:

 

    1. 8 bits.

    2. 9 bits.

    3. 10 bits.

    4. 11 bits.

 

 

Audio encoding parameters.

 

Go to the Audio section. The following parameters are available here:

 

  • Codec - the codec that will be used for compression of the audio stream. This parameter can take one of the following values:

 

    1. Mpeg Audio Layer - 1.

    2. Mpeg Audio Layer - 2.

 

  • Sampling Rate - the number of samples used for representation of one second of the audio stream. This parameter can take one of the following values:

 

    1. 48000 Hz.

    2. 44100 Hz

    3. 32000 Hz

 

  • Channel - the number and type of channels in the audio stream. This parameter can take one of the following values:

 

    1. Stereo.

    2. Mono.

    3. Join Stereo

    4. Dual Channel

 

  • Bitrate - the number of bits used for representation of one second of the audio stream.

  • Error protection - if enabled, error protection will be turned on during encoding.

  • Original flag - if enabled, the produced file's audio stream will be marked as original.

  • Copyright flag - if enabled, the produced file's audio stream will be marked as copyright protected.

  • Private flag - if enabled, the produced file's audio stream will be marked as closed.

  • De-emphasis flag - the type of de-emphasis. This parameter can take one of the following values:

 

    1. None.

    2. 50/15 ms.

    3. CCITT j.17.
