`vidScale`	The frame rate of the video, represented as scale over sampleSize.
`vidSampleSize`
`vidDuration`	The total number of frames of video, in the video timebase.
`audInfo`	If there is audio in the file, fill out the imAudioInfoRec7 structure.
`audDuration`	The total number of audio sample frames.
`accessModes`	The access mode of this file. Use one of the following constants: - `kRandomAccessImport` - This file can be read by random access (default) - `kSequentialAudioOnly` - When accessing audio, only sequential reads allowed (for variable bit rate files) - `kSequentialVideoOnly` - When accessing video, only sequential reads allowed - `kSequentialOnly` - Both sequential audio and video - `kSeparateSequentialAudio` - Both random access and sequential access. This setting allows audio to be retrieved for scrubbing or playback even during audio conforming.
`privatedata`	Private instance data. Allocate a handle using Premiere's memory functions and store it here. Premiere will return the handle with subsequent selectors.
`prefs`	Clip Source Settings data gathered from `imGetPrefs8` (setup dialog info). When a synthetic clip is created using File > New, `imGetPrefs8` is sent `beforeimGetInfo8` so this settings structure will already be valid.
`hasDataRate`	If set, the importer can read or generate data rate information for this file and will be sent `imDataRateAnalysis`.
`streamIdx`	The Premiere-specified stream index number. Only useful if clip uses multiple streams.
`streamsAsComp`	If multiple streams and this is stream zero, indicate whether to import as a composition or multiple clips.
`streamName`	Optional. The unicode name of this stream if there are multiple streams. New in Premiere Pro 3.1, an importer may use this to set the clip name based on metadata rather than the filename. The importer should set `imImportInfoRec.canSupplyMetadataClipName` to true, and fill out the name here.
`sessionPluginID`	This ID should be used in the File Registration Suite for registering external files (such as textures, logos, etc) that are used by an importer instance but do not appear as footage in the Project Window. Registered files will be taken into account when trimming or copying a project using the Project Manager. The `sessionPluginID` is valid only for the call that it is passed on.
`alwaysUnquiet`	Set to non-zero to tell Premiere if the clip should always be unquieted immediately when the application regains focus.
`filepath`	Added in Premiere Pro 4.1. For clips that have audio in files separate from the video file, set the filename here, so that UMIDs can properly be generated when exporting sequences to AAF.
`canProvidePeakData`	New in Premiere Pro CS6. This allows an importer to toggle whether or not it wants to provide peak audio data on a clip-by-clip basis. It defaults to the setting set in `imImportInfoRec.canProvidePeakAudio`. Warning Do not attempt to use this setting with growing files.
`mayBeGrowing`	New in Premiere Pro CS6.0.2. Set to non-zero if this clip is growing and should be refreshed at the interval set in the Media Preferences.

`noDuration`	One of the following: - `imNoDurationFalse` - `imNoDurationNoDefault` - `imNoDurationStillDefault` - use the default duration for stills, as set by the user in the Preferences - `imNoDurationNoDefault` - the importer will supply it's own duration This is primarily for synthetic clips, but can be used for importing non-sequential still images.
`isRollCrawl`	Set to non-zero value to specify this clip is a rolling or crawling title. This allows a player to optionally use the RollCrawl Suite to get sections of this title for real-time playback.
`hasPulldown`	Set this to true if the clip contains NTSC film footage with 3:2 pulldown.
`pulldownCadence`	Set this to the enumerated value that describes the pulldown of the clip: - `importer_PulldownPhase_NO_PULLDOWN` 2:3 cadences: - `importer_PulldownPhase_WSSWW` - `importer_PulldownPhase_SSWWW` - `importer_PulldownPhase_SWWWS` - `importer_PulldownPhase_WWWSS` - `importer_PulldownPhase_WWSSW` 24pa cadences: - `importer_PulldownPhase_WWWSW` - `importer_PulldownPhase_WWSWW` - `importer_PulldownPhase_WSWWW` - `importer_PulldownPhase_SWWWW` - `importer_PulldownPhase_WWWWS`
`posterFrame`	New in Premiere Pro CS3. Poster frame number to be displayed. If not specified, the poster frame will be the first frame of the clip.

Format Info¶

Member	Description
`depth`	Bits per pixel. This currently has no effect and should be left unchanged.
`subType`	The four character code of the file's codec; associates files with MAL plugins. For uncompressed files, set to `imUncompressed`.
`fieldType`	One of the following: - `prFieldsNone` - `prFieldsUpperFirst` - `prFieldsLowerFirst` - `prFieldsUnknown`
`fieldsStacked`	Fields are present, and not interlaced. Deprecated since Premiere Pro 7.0.
`alphaType`	Used when depth is 32 or greater. One of the following: - `alphaNone` - no alpha channel (the default) - `alphaStraight` - straight alpha channel - `alphaBlackMatte` - premultiplied with black - `alphaWhiteMatte` - premultiplied with white - `alphaArbitrary` - premultiplied with the color specified in matteColor - `alphaOpaque` - for video with alpha channel prefilled to opaque. This gives Premiere the opportunity to make an optimization by skipping the fill to opaque that would otherwise be performed if alphaNone was set.
`matteColor`	`Newly` used in Premiere Pro CS3. Used to specify matte color if `alphaType` is set to `alphaArbitrary`.
`alphaInverted`	If non-zero, alpha is treated as inverted (e.g. black becomes transparent).
`canTransform`	Set to non-zero value to specify this importer handles resolution independent files and can apply a transform matrix. The matrix will be passed during the import request in `imImportImageRec.transform`. This code path is currently not called by Premiere Pro. After Effects uses this call to import Flash video.

`pixformat`	The pixel format Premiere requests.
`flags`	`imDraftMode` - Draw quickly if possible, using a faster and possibly less accurate algorithm. This may be passed when playing from the timeline. `imSamplesAreFields` - Most importers will ignore as Premiere already scales in/out/scale to account for fields, but if you need to know that this has occurred (because maybe you measure something in 'frames'), check this flag. Also, may we suggest considering measuring in seconds instead of frames?
`fieldType`	If the importer can swap fields, it should render the frame with the given field dominance: either `imFieldsUpperFirst` or `imFieldsLowerFirst`.

} RawColorSpaceRec;

Member

Description

colorSpaceType

One of the following:

- kPrSDKColorSpaceType_Undefined
- kPrSDKColorSpaceType_ICC
- kPrSDKColorSpaceType_LUT // DO NOT USE after 14.x.
- kPrSDKColorSpaceType_SEITags
- kPrSDKColorSpaceType_MXFTags // DO NOT USE, Not supported.
- kPrSDKColorSpaceType_Predefined

profileRec

A structure describing the color space.

csSDK_int32  ioBufferSize;
void*        inDestinationBuffer;
PrSDKString  outName;

seiCodesRec

A structure describing the color space; used with H.265, HEVC, AVC and ProRes media.

csSDK_int32  colorPrimariesCode;
csSDK_int32  transferCharacteristicCode;
csSDK_int32  matrixEquationsCode;
csSDK_int32  bitDepth;
prBool       isFullRange;

Colorspace can be described via multiple way, type depends on colorSpaceType.

If type is kPrSDKColorSpaceType_Predefined - Color space is specified via predefined strings from PrSDKColorSpaces.h.

If type is kPrSDKColorSpaceType_ICC - Color space is specified via ICC profile in profileRec.

If type is kPrSDKColorSpaceType_SEITags - Color space is specified via enums codes for color primaries (C), transfer characteristic (T), matrix equation (M). Supported C-T-M enums are defined in PrSDKColorSEICodes.h.
