SCRATCH / Play Pro v9.1 Beta Release


The current SCRATCH v9.1 Beta can still be used with a normal v9.0 license. However as new beta updates come and we get closer to the actual release version there will be an update version that also requires an upgrade of your license. If you have a valid v9.0 license your license is automatically updated to include the new v9.1 version. After installing the new build your have to re-activate your existing license key. Contact if you have any question on licensing for this beta version.

Note that this version contains a number of changes from the current 9.0 production release in how certain formats are processed with regards of colorspace and transfer function. As such, this build it is not backward compatible. Before upgrading, you should maintain a backup and are advised not to upgrade in the middle of a project.


  • Backup all your settings and projects before installing any new version of SCRATCH.

June 13 '19, build 1016

  • Includes latest ARRI SDK to version with support for new upcoming camera models.
  • Includes latest Apple ProRes RAW SDK to version 20190607_12551 with fix for Intel UHD Graphics 630 and slightly better overall performance.
  • Includes latest Oculus SDK to version 1.37.0. with support for the latest/ upcoming Oculus models.
  • Updates on ACES CTL transformation processing to increase the accuracy of the results.
  • Fix on reading filemask- and output templates which could fail a render since the previous build.
  • Various updates on the SCRATCH Report tool - such as auto-detect and recalculate the clip file-size if needed.
  • Various fixes and updates on the custom commands. Additional command line parameters were not passed properly on OSX. New Reset button for the Nuke and After Effects custom commands to update the round trip scripts to the latest version.

June 4 '19, build 1015


  • New first-time-start setup screen to automatically setup matchbox shader plug-ins and after effects / nuke bridges.
  • Added a new Diffusion plug-in.
  • Updated the generic XYZ-ACES transforms used by the color management to get similar results to IDT transforms of camera specific formats.


  • Various fixes on handling per-frame-metadata which could slow down the system considerably. You now need to explicitly enable per-frame-metadata in the Advanced System Settings. .
  • Camera-specific metadata is no longer translated in the Chinese version.
  • Deselecting a report metadata column could crash SCRATCH.
  • It was not possible to use Unicode characters in the filename specification for the BWF audio export.
  • Fixed an issue with the EDL editor where editing the name would in effect edit the reel.
  • ARRI Camera ID and Camera Index metadata showed incorrect values.
  • CDL values from an EDL were not passed on to placeholders. Also, no longer include brackets around the SAT parameters of a CDL when included in an EDL/AAF as that confused certain software.

May 24 '19, build 1013


  • Added a Single Track/Multi Track audio option for QuickTime/mp4 (ProRes/H264|5) output. The Multi Track option puts each audio channels in a separate tracks in the QuickTime. Also, you can now also set a specific audio channel layout in the ProRes encoder for the QuickTime output; mono, stereo, 5.1, etc.
  • Updated version of the HighlightBloom effect.
  • Updated Chinese translation / 更新了中文用户界面翻译


  • The Color Space Converter plug-in was not working correct with images that had an Aspect.
  • Updating metadata in the Media Browser could be sluggish since the last 2 builds.
  • EDL comments were not added as notes to placeholder items.
  • Fixed a potential crash when copying a construct that had '%s' in the name.
  • Enabled the "A-Relative" option in the paste-mask used with the Copy-Grade function. This helps in a scenario where the source material was trimmed (using e.g. same-as-source render) and the in-points changed.
  • The softness settings of a layer could get into a state that made the layer unusable. Using the Reset on the calculator resets the Softness state.
  • Unicode file names did not always work correctly when creating raw H.265/HEVC or fast-start H.264 mov/mp4 files.

May 16 '19, build 1012


  • Added 4 output-templates for PIX/DAX/MediaSilo/Copra rendering.
  • Added an Advanced System Setting to enable legacy 32-bit QuickTime reader and writer. By default the Legacy QT reader and writer are no longer available in SCRATCH. This way we prevent the "non-optimized" warning from OSX when starting SCRATCH the first time because it instantiated a 32bit element.
  • Added a Refresh button to LUT cycler to force update the list.
  • New option in EDL Assemble to update a shot name from the name / reel or markers in an EDL.
  • Option to add additional command line parameters with a custom command, making it easier to re-use a script with different settings.
  • When there is pending xml script for a project, the Refresh button now only processes the xml and not do the full project refresh.
  • Clarity menu from Numeric is now animatable.


  • When using a (sub)folder in the file-mask for exporting grades (Media Browser), the export failed because the sub-folder was not created properly.
  • Take/Scene updater now also the alpha-numeric character at the end of the Take field.
  • The Colorspace plug-in did not show up in regular SCRATCH (only with a VR license).
  • The new Vector settings were not always properly preserved when copying a shot/layer of when the Vectors was the only item in a grade.
  • A reset of Source LUT in the Media Browser did not work as expected.
  • Update on memory management where systems with relative small internal memory but working with big (8k) images could become unresponsive.

May 13 '19, build 1011 (first open beta release)


Media Formats

  • Increased render speeds through more efficient readback of the image from the GPU. The performance-gains depend on the specific setup / current bottleneck.
  • RGB to YUV conversion is now done on the GPU to further improve performance for output to e.g. ProRes, DNx and H264/5.
  • Support for multi-channel EXR where you can create a custom mapping to the RGBA channels in SCRATCH.
  • Added an extended control-set for ProRes RAW where you are able to select any of the available color spaces and transfer functions in SCRATCH with the debayer.
  • Added support for dynamic (per-frame) metadata. Currently only for ARRI Raw (e.g. camera roll and tilt, lens focus distance metadata items and more). As it is not fully clear yet what the impact on performance is, this feature needs to be enabled explicitly through the Advanced System Settings. Dynamic metadata shows up in the metadata stack and is included in EXR render. Note that in previous versions you needed to explicitly enable the option to write extended metadata in EXR. In this version it is enabled by default, but can be switched off using the relevant Advanced System Setting.
  • Support for writing Cineform movie and dpx-c formats.
  • Support for reading Uncompressed 4:2:2 media with the regular QuickTime reader.


  • We added a "New Timeline" option in the File Browser when loading media. After selecting the folder to load, this option opens a dialog where the user can set how to load the media (new timeline, timeline per subfolder, etc), apply specific framing and LUTs and do an automatic audio sync with any audio anywhere in the selected folder. This will speed up the loading and managing of media substantially. 
  • We added a Same-as-Source render option in the Render tab. There you can select any node from the output tree and select it to render each source clip with its original resolution, frame rate and aspect. This works for almost any output format except for e.g. DNxHD, which in itself has a resolution restriction.
  • SCRATCH has a new / enhanced color-space management where the gamut and transfer function are separate entries. SCRATCH now includes a series of camera specific gamuts and gamma spaces like Log-C, V-Log, Alexa Wide Gamut, etc. as native. Besides letting SCRATCH handle all the necessary color-space conversions automatically, you can also use the new Color space plug-in that you can apply on any level in your composite or output tree to do the necessary transforms. On top of this there is also a new OpenColorIO plug-in to do any needed transform. This plug-in automatically hooks into your OCIO settings from other applications you might have or you can set it to a specific configuration file from the Advanced System settings. Using this plug-in ensures that certain conversions are exactly the same as done in other software that uses OCIO (note though that most to all of the transforms in SCRATCH color management are based on standard transfer-curves and gamut-chromatices).
  • MXF DNx output now includes the audio timecode (slip) in the metadata, which is properly interpreted by Avid Media Composer. The DNx writer now also adds a TapeID column with the audio file name if the source clip has audio synced/linked to it. This way you do no longer need to supply separate ALE files with your output to editorial to transfer this information.
  • SCRATCH now supports AVID Locators: either load them from an EDL or as a separate file (through the Import Conform in the Construct tab). To preserve any Locators when using a Placeholder conform, all notes / locators are preserved in the locator nodes.
  • Various metadata updates. Audio timecode was added as standard element in the Metadata stack in the Construct, Edit and ColorFX tabs. We also added a standard Circle Take item which can also be set in the Scene/Take updater panel and is available as #circled hash code for file-masks and burn-in. Circle-take info is also read from audio metadata that is used in a sync as well as any comments from the audio file. 
  • The Scene/Take updater dialog has two new buttons: Circle take and increment scene number or letter.
  • A new Advanced System setting automatically sets a clip’s reel-id to the clip-name when loading media. This speeds up your dailies Avid workflow.
  • Conforming updates. An AAF/XML conform can now also use the direct file-reference in the AAF or XML file (rather than matching from an existing timeline or external folder). The EDL conform now auto detects and creates video tracks from multi-track EDLs. For the EDL export we fixed an issue were dissolves that started in the A-shot were not properly written to an exported EDL.
  • We added an '[Original]' entry with the timeline sort options to easily revert to the original order after sorting on e.g. name or scene/take. The original sort order is maintained over sessions and is in fact the order of the slots – including slot length and transitions.
  • We extended the quick keys for slipping video in the Editor and also apply them to audio slipping when in the Audio section of the Editor. The '<' and '>' keys slip the video/audio 5 and 1 frame respectively. The ',' and '.' keys slip the audio/video with 1 and 0.2 frames respectively.  
  • This update contains new version of the SCRATCH-to-Nuke and SCRATCH-to-AfterEffects bridges, which allow for a smoother roundtrip to and back from that software.Support for multi-clip selections, include clips from SCRATCH staging, option to either load back into the SCRATCH Tray or as version in the timeline, SCRATCH remembers opening a shot in Nuke/AE and will open the same project again when selecting the same shot again. 

Creative Tools

  • A new Hue-Saturation and Hue-Luminance Grid tool replaces the more traditional 6-Vectors in the ColorFX grading toolset. The Hue-Sat grid can be operated in different modes: Linear vs Log/Log2 and displayed as a (color) circle or rectangular grid. Note that the 6-Vectors are still applied if you come from an existing project. You can also still display the 6-Vectors controls rather than the new Grid control if you prefer, by adjusting the relevant setting in the User Preference panel in ColorFX.
  • An update on the Curves: you can now directly add and remove curve handles from the Curves menu and have an indicator to see what section of the curve is represented by the image that you are hovering over with the cursor.
  • In the LUT menu in the ColorFX tab, we added a LUT Cycler option to easily cycle/browse through other LUTs in the same folder as the selected (grading) LUT.
  • The motion estimation mode in the Re-timer was updated to increase both the speed and quality.
  • Animation Editor updates. The Editor now supports a series of filters to tweak your animation: LowPass, HighPass, Smooth, Reduce (the number of keyframes) and Noise (to generate random values). To manage all animation channels more easily, the editor now has filter options only show active channels or only the channels of the selected layer. Furthermore, you can now directly enter values in the editor by shift-clicking a keyframe. When selecting layer-vertices in the View Port, SCRATCH will now automatically select the corresponding channel in the editor and vice-verse. Note that SCRATCH will now by default only show the x and y of any vertex in the Editor. If you want to see also the in/out handle of each vertex then you need to enable to relevant Advanced System setting.
  • We added various keyboard shortcuts for managing animation keyframes while in the ColorFX or Edit tabs:
  • Ctrl + click parameter. If Animation Off: reset value to default. If Animation Manual/Auto: create keyframe with default value or if parked on existing keyframe, change to default.
  • Ctrl + Shift + click parameter. Create keyframe with current value
  • Holding Ctrl + changing parameter also creates a keyframe directly. If Animation Off: Set Animation to "Manual" and create keyframe. If Animation set to Manual/Auto: Keep it Manual/Auto and create keyframe.
  • Alt + click parameter = delete animation (all keyframes), but keep current value
  • Alt + Ctrl + click parameter = delete all animation keyframes and reset to default value
  • Shift + Alt + click parameter = delete keyframe under the cursor for this parameter
  • We added new effects plug-ins with the standard installation of SCRATCH: Denoizer, Grain and HighlightBloom. All of these effects are aimed to be simple and fast and usable in an environment where you need a quick grade. They are not aimed to replace more advanced third party tools you might use in a finishing context.
  • We added the *.vlt extension for loading (Panasonic) 3D LUTs.


  • The Flip/Flop Orientation controls have been moved to the Media menu. The Flip/Flop controls in the Editor are now applied to the Source-orientation and no longer update the framing to make things more consistent. Also, any flip/flops in a conform are now also applied to the Source Orientation instead of the framing. 
  • Relabeling of the "Setup" menu to (more explicit) "Framing" in both the ColorFX and Edit tabs. The shot pipeline settings have been moved to the Config-menu in the ColorFX tab.
  • File-size is now interpreted and displayed in the correct units (Mb/Gb) in both the metadata stack and in the various reports that you can generate (which also include the total size of all selected clips).
  • Updated AJA SDK to version incl. support for io 4K Plus, Kona 5 and support for 4K-2SI (2 Sample Interleave) for AJA SDI output.
  • Updated BMD DeckLink SDK to version 11.1. which adds more frame rates and 8K display modes.
  • Allow to start dragging clips directly from the search dialog.
  • Added #sfolder hash code to get specific sub-folder of a source clip. Updated the #spath hash code; without parameters it displays the full path, #spath[0] returns the relative path from the project media folder and #spath[1…n] returns the n subfolders of the source clip.
  • Allow adding custom data to the sync-player broadcast message. Set #code template in the 'Sync Player extended data' sconfig.
  • Quick keys updates and tweaks: the J,K,L keys did not work correctly when in the Canvas menu. Also the 'i' quick key is no longer used for the Canvas and now always sets the in-point for a range.
  • We added an option to directly install the Matchbox (shader) plug-ins collection from the System Settings menu.
  • Added function in the Media Browser - Grade tab to remove all empty layers from the selected shots to easily cleanup your grades. An empty layer is defines as only having a canvas - no grading or fill/matte definition.
  • We added a search option for the (ever growing) Advanced System Settings list.

Play Pro Specific

  • The render-dialog in Play Pro now also has an explicit same-as-source option to render all selected clips to their native resolution, framerate and aspect.
  • The Render can also include a standard burn-in overlay with source shot metadata.
  • You can now link and slip external audio to a clip in the Player tab.
