1. QUICKTIME FILE READER When you load an existing QuickTime into SCRATCH the FX Controls menu will show you additional configuration settings for playback Bit depth and Quality The actual effect of the settings on playback depends in the end on the specific codec with which the QuickTime was originally created For some QuickTime codecs SCRATCH is unable to determine all properties required for correct playback from the file alone For this SCRATCH has two addition SConfig file variables to which you can link a specific codec by adding the codec s identifier to it The identifier is displayed after the name in the FX Ctrl menu The settings are e QT_10BIT_CODECS QuickTime media using these codecs are by default managed having a bit depth of 10 e QT_ENDIAN_DECODE_BYTESWAP QuickTime media using these codecs are treated having a reversed byte order APPLE PRORES ENCODER FOR WINDOWS On OS X you can render ProRes using the regular QuickTime file writer Render ProRes on Windows is done by a separate Apple ProRes Output node e Video select the ProRes sub format and if the sub format allows it add an alpha channel e Audio similar to the regular QuickTime encoder select the channels you want to include 216 CINEMA CRAFT H 264 ENCODER The Cinema Craft H 264 encoder generated high quality encoded video even on relatively low bit rates The encoder is for the time being only available on Windows and resolution is limited to
2. AUTO EXPORT OPTIONS When setting the Auto Export option SCRATCH will on every project exit or refresh export project data from the project database to an external file which can be used by third party applications In case the export is set to HTML SCRATCH will ask before doing the export as this might potentially be a lengthy procedure The exported data contains information about all aspects of the Project and can be used by third party systems programs or scripts to determine and use the state of a Project even if SCRATCH is not running Project data can either be exported as XML or HTM To generate HTML SCRATCH generates XML first and uses that in a customizable XSL transformation In this process SCRATCH will also create a proxy image file for each shot in the project When selecting HTML as export format two additional options become available The Overwrite option is enabled by default meaning that on every export the proxy image of every shot is re created Disabling the option will only create an image proxy when no image file for the shot is present yet in the designated location This will speed up the export process but does not ensure that the image is the most recent available The second option available for the HTML export is to create a LUT per shot in the project This LUT can be used in third party systems The LUT can either be 1D or 3D The 3D LUT has by default size 32 and depth 16 The creation of the LUT is also linked to

ANIMATION in Chapter 7 for more details about how to animate parameters in SCRATCH SOFTNESS The Softness parameters allow you to create a more seamless transition between the Layer and the image below By increasing the Softness you can smooth the edge of the Canvas shape 187 SOFTNESS The Softness parameter determines how far away from the Canvas shape the softness effect will extend When softness is added a second line appears around the Canvas shape to indicate the boundary of the softness effect In Edit mode each control point has an associated softness point Each softness point is tied to a control point and is added or deleted along with the control point The softness points can be repositioned independently from the control points while in the Edit mode SMOOTH By default the soft edge filter uses a Gaussian fall off function to create a more even transition from the Canvas to the image below The Smooth option button is for backward compatibility When switched off the softness function uses a linear interpolation function which was implemented in in older versions of SCRATCH With the linear function two additional parameters become available to fine tune the linear fall off function by implementing additional gain and gamma to the fall off INVERT The Invert button switches the Canvas so that any color adjustments are applied outside the Canvas shape instead of the default inside the Canvas shape OPACITY T

In essence the image is projected onto the CONstruct working frame and will not be affected by the orientation of the Canvas Map On Canvas With Map On Canvas set the image is mapped onto the Canvas surface This means it is affected by any change in orientation of the Canvas This is the equivalent of the Texture image being painted onto the Canvas If the Canvas is rotated the image rotates as well Pinned Mode for Bicubic shapes the texture is mapped directly onto the Bicubic deformed surface FRAME SLIP The Frame Slip allows you to offset the relationship between the current base frame and the frame being used for the Fill or Matte texture You can use the Frame Slip to align the timing of several shots so that all elements are synchronized Note Frame Slip is only active when an alternate image has been loaded It is not possible to slip the default image IN OUT The IN and OUT controls allow you to further synchronize the relation of the base shot and the shot used for the Fill or Matte texture by setting the in and out points of that shot LOOP MODE The LOOP MODE controls how the shot that is used for the Fill or Matte behaves if that shot is shorter than the base shot Once The shot clip plays normally until the OUT point is reached After that point the final image is held as a freeze frame until the end of the base shot Loop The shot plays normally until the OUT point is reached After that point the shot lo

128. MENTS SCRATCH s performance relies primarily on the speed of the graphics accelerator and disk sub system in your host computer system System RAM and CPU type are also important but in general with more latitude Below is a list of requirements recommendations and considerations when setting up a new system HARDWARE e Graphics accelerator SCRATCH will work with most modern graphics cards with OpenGL and OpenCL support SCRATCH is tested on high end NVidia Quadro and AMD Firepro cards Please see for an up to date overview of tested graphics cards and recommended drivers in the Driver Chart available on the Support Site The exact requirement of the graphics cards also depends on the type of media that you work with some media require a GPU for debayer while other rely more on CPU decompressing Some media will benefit from multiple graphic cards in the same system The recommended minimum resolution to work on is 1920x1200 SCRATCH supports various SDI output cards NVIDIA Bluefish AJA and DeckLink e High speed disk sub system SCRATCH plays back media files directly from the disk drives without converting to an intermediate file format therefore the performance of SCRATCH is tied directly to the performance of the disk sub system Depending on the type of footage you are planning to process you will need more or less bandwidth throughput from your disk system o For real time playback of 2k DPX material you need at least 350 400
129. Mb s o For compressed material like e g RED r3d 35 60 Mb s disk throughput requirements is less but more processing power is required from the CPU Note that to render write uncompressed material you will need 350 400 Mb s write speed again o If you are planning stereo projects or using 4k uncompressed footage disk performance requirements will more than double e x86 64bit compatible CPU Even though SCRATCH relies in general more heavily on the GPU than the CPU the choice of CPU is important Some file formats require substantial CPU power for decoding next to GPU power for debayer e g RED Sony Another factor might be that certain plug ins you are planning to use require CPU processing e 12GB Memory minimum In a 64 bit operating system there is virtually no limit to the amount of memory that can be used However the marginal utility of increasing quantities of memory do diminish more memory will allow SCRATCH to cache more data However you will primarily benefit from that larger cache as long as your media working set fits in the cache completely e PCI slots Make sure the system has enough expansion slots to accommodate current and future needs e g professional sound card disk controllers capture card RS422 connector for deck control on play out decoder cards r3d etc For the MAC you can use an Extension Chassis OPERATING SYSTEM As of version 6 0 SCRATCH is released as a 64bit application on both Windows and O
