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 will allow the person creating and uploading files to optimize their files for use within the Proofing Workspace.

 

The following are recommended settings and options for all image based file assets. These recommendations will allow to reduce risk of processing errors and ideal end-user consumption.

It is important to note that these recommendations are not limitations.  You do not need to follow all of these but you may potentially run into conversion or display issues otherwise.

  • The image dimensions should be less than 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 have metadata (such as EXIF tags) stripped - for the sake of file size.

 

ConceptShare's internal document format is PDF.  Any document not in that format already will be converted to PDF.  There are some features of PDFs not supported, or only partial supported.  Below is list of some of the features you may want to work around when creating your PDFs.

Generally speaking it is recommended that if the software producing the PDF has an option to “Optimize for Web”, that it be leveraged and used.

 

Embedded Images

ConceptShare’s document engine 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 has 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 a 5,000px by 5,000px large image in a PDF that is scaled to a much smaller size.  Resize those images accordingly before use to prevent the end-users from having to render the large image and scale it as well.

 

Font Features

  • All required fonts should be embedded into the PDF, otherwise fallback fonts may lead to discrepancies on display.

 

Document Page Size

  • Since documents are rendered in CS at 110DPI, we do not recommend using 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:  Where possible, create the document that is flattened and minimizes the number of blends/transparencies.

 

Office Documents:

 Microsoft Excel:

For Excel documents, ConceptShare will honour 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’s document engine currently does not support interactive PDF features such as:

  • 3D
  • PDF Forms (XFA or AcroForms)
  • Embedded Content (Flash)
  • Javascript
  • PDF Annotations
 

Video will be re-transcoded by ConceptShare if and where necessary.  Additionally ConceptShare will perform a bandwidth test to select the most appropriate version based on the client’s connection and bandwdith.  However, there are optimizations that can be done, that will speed processing time and allow for greater control over the video process.

 

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.

Medium Rendition

High Rendition

Width >1920

OR

Height >1080

Yes (Scaled)

OR

Height 360-720

Yes (Scaled)

Yes

No

Width <640

AND

Height <360

No

Yes

(low rendition becomes the default)

No

 

In order to bypass the primary transcoder within ConceptShare and save processing time, you can have your video in a format which is already our proxy format in which case the video and audio streams will be copied directly to the proxy instead of re-transcoding the video.  Any video not meeting these requirements will be converted to conform.  Below are the current proxy requirements for ConceptShare.

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

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