What are the recommended settings for my file types?

The following are recommended settings and options for different file types that can be uploaded into ConceptShare. These recommendations are here to help you optimize the experience from creating, to uploading, and for all those people who will later need to view and review the uploaded assets.

 

The following settings apply for all image based assets. These settings will reduce the risk of processing errors and improve the experience for those reviewing your assets. A failure to follow these recommendations may result in conversion or display issues for reviewers.

Various web browsers have different maximum image sizes they will support. If you upload assets beyond this size, there is the potential that the image will not display correctly or in its entirety and the browser may not provide any indication to reviewers that there are missing portions of the image. As of Spring 2018, the average browser limitations are 8196px * 8196px. If you follow the recommended settings you won’t encounter these sort of issues.

For optimal results:

  • The image dimensions should be kept under 4,000px wide by 4,000px high.
  • The image should be in the sRGB color space.
  • The image should be at 72dpi.
  • The image should not leverage any specific ICC color profiles embedded.
  • The image should remove metadata (such as EXIF tags) - for the sake of file size.
  • If given the choice, use web optimized image formats such as PNG and JPEG

 

The ideal format for displaying documents in ConceptShare is PDF. If you choose not to export your documents to PDF and instead upload them directly in their native format (ex. pptx, docx, xls, txt), ConceptShare will first convert your document to PDF so that they can be displayed to reviewers inside a web browser. There are some features of PDFs which are not supported, or only partial supported.

Generally speaking, if possible, it's best to export the native file to a PDF using the software that generated that document, because that software is most likely the most capable to create a PDF copy. This minimizes the risk of any discrepancies between the PDF version and the native file format. It also means you see what your reviewers will see. If the software you're using to export to PDF has the option to produce a web optimized PDF or at least has the option to optimize the original document, we highly recommend that this feature be used.

 

Embedded Images

ConceptShare’s currently does render embedded images with different color spaces other than sRGB (such as CMYK), however, those color spaces not in sRGB will be converted to sRGB upon display.  This conversion process produces an inherent color shifting, so it is recommended that when creating your PDFs you ensure your embedded images are in sRGB.

To improve performance you will want to ensure you are using embedded images with 110dpi or less.  Try to use JPEG encoding for color images/photos in RGB color space when possible.

Finally, ensure the image is the correct size for the given application.  For the purposes of web review, there typically isn’t a need to have anything larger than a 5,000px * 5,000px image in a PDF that can't be scaled to a much smaller size.  Resize those images accordingly before use to prevent the end-users from having to download and render these unnecessarily large images and then scale them down as well.

 

Font Features

  • All required fonts should be embedded in the document, otherwise fallback fonts will have to be used which will lead to discrepancies when displayed to reviewers.

 

Document Page Size

  • Since documents are rendered in CS at 110DPI, avoid uploading assets with page sizes larger the 36 inches in either width or height.  This will result in a rendered page of no more the 4,000px by 4,000px (to conform to image recommendations).

 

Document Complexity

  • Image Reuse: If an image is re-used several times throughout a document, it is recommended to use PDF features of referencing the same image within the PDF as opposed to having the image embedded several times.  This is typically handled by most software automatically during the creation process.
  • Layers, Transparencies, Blends:  Whenever possible, create the document such that it's flattened and minimizes the number of blends/transparencies. Layers and transparencies consume large amounts of the browsers resources and significantly slow performance of the end-user browser. This makes for a poor reviewer experience for everyone downstream who needs to work with your assets and review them.

 

Office Documents:

 Microsoft Excel:

For Excel documents, ConceptShare will honor what the page setup and layout settings are in the Excel document. You can use Excel features such print preview, shrink to fit single page, and print area features to help determine how your document will be converted by CS into a PDF. To provide maximum control you can save the Excel document as PDF yourself and upload the PDF directly. 

 

Microsoft PowerPoint:

For PowerPoint documents, ConceptShare will convert them to PDF. This means that certain features of PowerPoint are not supported by ConceptShare such as animations and embedded control (videos, flash, etc.).

Additionally, it is desirable at times to include speaker notes into the export but unfortunately ConceptShare does not support this feature at this time. As a workaround you can save the PowerPoint slides to PDF manually and include speaker notes there, and upload that PDF to ConceptShare.

 

ConceptShare currently does not support interactive PDF features such as:

  • 3D
  • PDF: annotations
  • PDF: any embedded interactive content (ex. embedded Audio or Video)
  • PDF: forms (XFA or AcroForms)
  • Embedded Content (Flash)
  • Javascript
 

ConceptShare will transcode uploaded video files into three versions: low, medium, and high quality renditions. Once these different versions are available, ConceptShare will test the user connection and display the quality rendition most appropriate to the user based on their available bandwidth.

  • Note: ConceptShare can transcode only the lower quality renditions (since we can't "enhance" and produce a higher quality version of your video ... despite what watching CSI might try to convince you)

In order to bypass the transcode step and save processing time, you can upload your video in a format which already matches our preferred format (for details see the Medium Default section below).  

Determining Which Renditions Will Be Available

Depending the size of the input video, a number of renditions or proxies may be created.  The below chart will help determine what will be available based on the input dimensions.  In some cases the video may be transcoded and scaled proportionally.  Users can upload video files to ConceptShare at any frame rate, but ConceptShare will render any file exceeding 30 fps at 30 frames per second.

Users can upload video files to ConceptShare at any frame rate, but ConceptShare will render any file exceeding 30 fps at 30 frames per second.

Safe Zones
ConceptShare’s renders safe zones at 90% for action areas and 80% for title areas. Additionally, center-cut safe areas at 14:9 and 4:3 are 70% wide and 65% wide respectively, at 90% height.

Timecodes
ConceptShare does not currently support Drop-Frame Timecodes. All video timecodes are rendered in Non Drop-Frame Timecodes.

ConceptShare currently supports Timecode Offset. When uploading a section of video that is a subset of a larger master video (i.e. the frames of a video file consisting of 00:30:00 to 01:00:00), ConceptShare will display the file timecode offset as such, assuming the Timecode Offset metadata is properly stored in the video.

Closed Captioning/Subtitle Support
ConceptShare does not currently support Closed Captioning or subtitles; however, it is technically possible to integrate Closed Caption support. This development is not currently part of the ConceptShare roadmap, and would be driven by customer/partner demand.

Adaptive streaming
ConceptShare does not currently support adaptive streaming; however, ConceptShare is currently evaluating adaptive streaming technologies. This development is not currently part of the near-term ConceptShare roadmap, and would be driven by customer/partner demand.

In the *.ZIP file of your animation, make sure there is only one HTML within the published animation folder per file.
  • "Duration (s)" (Capture Duration is bound to a value between 1 and 300) - if not specified, capture duration is set to 15 seconds
  • "Width (px)" (Width is bound to a value between 1 and 10000 if specified) - if not specified, auto-detection is used
  • "Height (px)" (Height is bound to a value between 1 and 10000 if specified) - if not specified, auto-detection is used

Known Limitations:

  • Scalable Vector Graphics (SVG) are not currently a supported format in ConceptShare, and therefore will not render if embedded in HTML5 ZIP files.
  • Use of web fonts is not a supported when uploading HTML5 ZIP files. Instead, include the font files in the ZIP file and reference the local fonts.

The proxy that is used is the same as for video assets, an MP4 container with H264/AAC encoding.

The web page that you are looking to upload will be saved as a single screen capture, which is important to be aware of when there are video and animations elements on the page.
  • Ensure the link if for a publicly accessible website
  • The upload can support basic authentication
  • Don't include direct links to files (For instance, a link to a zip file will not be uploaded.)
