Using Telestream Episode
Remarks
$ If using the CAVLC entropy coding algorithm (see step 7), you must
enable
Limit data rate to and type a value. If using CABAC, you can
enable or disable this option.
$ The Limit data rate to option applies to the video portion of your
encoded file only. When factoring in the encoded audio, the overall data
rate for your encoded file may exceed the specified data rate limit. To
minimize the impact of the audio on the overall data rate, select
AAC or
AAC QuickTime as the Audio Codec in the Inspector Panel.
6 Under Compressor, set the Quality level for your encoded video. Your
desired quality is delivered on each frame at the lowest data rate possible,
depending on the complexity of the video.
7 Select the entropy coding Algorithm to be used during compression:
$ CABAC Uses the CABAC coding method, and defines the video stream
as H.264 Main profile.
$ CAVLC Uses the CAVLC coding method, and defines the video stream
as H.264 Main profile when
Frame Reordering is selected. Otherwise,
the video stream is defined as H.264 Baseline profile.
¦NoteCAVLC is not supported when encoding to a frame size that has a
width greater than 720. In this case, CABAC will always be used for encoding.
8 If your source video is interlaced and you want to de-interlace your video
before encoding, select
De-interlace video. This option can be used to
display your encoded video on a monitor that displays lines progressively,
such as an LCD or computer monitor. For all other instances, make sure this
option is not selected.
¡ Important If your interlaced video is being scaled, either because you
applied an effect in your project or specified a different frame size for export
(see step 12), don’t use this option. Instead, use the
Deinterlace option
under
Video Filters in the Inspector Panel to de-interlace your video.
9 Select the H.264 level that you want to be used to encode your video.
