Export images in bview
Export as images or movies from Bview is via Export button under the timeline, it opens a window containing the following parameters :
- Source : choose from CURRENT (save current sequence), MODULE (save current module), IN/OUT (export frames between IN and OUT bounds), ALL (save all sequences contained in Bview).
- begin : starting frame.
- end : ending frame.
- remove_alpha : to remove alpha in the save (used to reduce the weight of the file for delivery).
- apply interface settings : apply the selected options in the interface (lut, brighten, gate...) to the image/movie output.
- apply annotations : insert annotations to the image output.
- anim : animated sequence.
- stereo : when checked, allows you to save two files (left and right).
- file_name : destination file name and path.
- file_format : file format (PNG, DPX, MOV...).
- color_space : color space (LINEAR, SRGB, CINEON...).
- as_link : save as link.
Export as DPX images with DPX Options to define parameter :
- dpx_depth : bit depth.
Export as EXR images with EXR Options to define parameter :
- exr_compression : compression algorithms.
Export as TIFF images with TIFF Options to define parameter :
- tiff_compression : compression algorithms.
Export as JPEG images with JPEG Options to define parameter :
- jpeg_quality : quality.
Export as images (PNG, CINEON, EXR, JPEG, etc.. ) with File Options to define parameters :
- frame : frame number on which the sequence begins.
- padding : sequence padding.
Export as movie (.mov) with a set of options to define codec and parameters.
For the moment, only H.264 and DNxHD codecs are available.
Parameters are not customizable, predefined profiles have to be selected.
3 options can be set for an H264 export.
- H264_bitrate : video data rates are given in bits per second. The data rate for a video file is the bitrate.
- H264_frame_rate : a frame rate is the frequency at which an imaging device produces unique consecutive images called frames.
- H264_profile : set a profile on the output stream. If a profile is specified, it overrides all other settings which guarantees a compatible stream.
- baseline : mainly for low-cost applications that use few resources, this profile is widely used in mobile applications and video conferencing.
- main : originally intended for consumer applications, distribution and storage, this profile has become less important since the release of high profile which has the same purpose.
- high : main profile for broadcast and disk storage, especially for high definition television (profile was adopted for HD DVD and Blue-Ray as well as the French digital TV high definition).
It is possible to redefine the output resolution by changing the resize mode resize_mode which is at NONE by default :
- ABSOLUTE : offer standard sizes (HD, 2K, 1K) or CUSTOM mode to define its own values of width/height.
- RELATIVE : apply a multiplication factor to the width and height of the input size: keeps the ratio of the image.
