Blackmagic Design H.264 Pro Recorder Manuel D'installation Et D'utilisation page 10

The Project Video Format defines the frame size of the current H.264 project. Choose "Native
(Progressive)" for full resolution encoding of your video or select from a number of popular
device presets including iPad and YouTube. H.264 Pro Recorder automatically detects the
frame rate of your video.
Video formats are provided for popular devices
as well as full resolution, Native (Progressive) video.
The Capture File Format always sets the video codec to H.264, and the file format to MP4,
when using H.264 Pro Recorder. Other choices appear in this menu when using other
Blackmagic Design capture products.
The Quality button provides access to the H.264 encoding settings and is only available when
H.264 Pro Recorder has detected a valid video input signal. We recommend leaving the
maximum bit rate unchanged from the default setting.
Set the storage location for your captured video and audio and choose whether to stop capture
or playback if dropped frames are detected.
Standard definition projects are set to the 4:3 aspect ratio unless you enable the Anamorphic
SD 16:9 checkbox.
Usually video applications stop playing video if you send them to the background. If you want
Media Express to keep playing video through your Blackmagic video hardware, even if you
open another application in the foreground, enable the checkbox to "Continue playback when
in the background".
The final options relate to tape decks with RS-422 deck control.
Your tape deck requires a pre-roll of a few seconds before performing an edit so the tape
speed is stable by the time it is used for an edit.
Timecode offsets can also be set to calibrate the timecode to the video.
