PCM Sound Encoding [ Create - Create options... Alt+O - Export as: - Settings - Sound tab ] There are no licensing requirements for PCM encoding. Compression type PCM encoding. There is also an option to not include sound in your demonstration. Compression preset Instant Demo offers five sound compression presets and a custom preset for each compression type. Quality For PCM this setting specifies the number of bits used to encode the audio data. Using 16 bits gives superior quality sound and poorer compression. Using 8 bits gives higher compression and poorer quality sound. Channels The number of audio channels to encode (stereo or mono). Sample frequency The output sample frequency of your encoded audio file. Instant Demo performs a high quality sample conversion (if required) during the encoding process. Lowering the frequency may produce poorer quality sound depending on the frequency range of the sound source. Lowering the frequency will provide higher compression. Raising the frequency above the source sound file sample frequency is not recommended as this will not improve sound quality, and it will increase the size of your video file. For a typical voice sound track, a sample frequency of 11kHz will provide good compression with little loss in sound quality. |
