Video Settings/Defaults

Video Ingest and Playback
ConceptShare’s default video proxy playback settings are as follows:

  • Framerate: 30 fps or less
  • Codec: H.264 (video), AAC (audio)
  • Size: 1080p or less
  • Colorspace: YUV420p
  • For full specifications see: Supported/Recommended Default (Medium) Rendition Proxy Settings

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.

ConceptShare Video Proxy Settings
ConceptShare transcodes each ingested video file into three proxy files: low rendition, medium rendition, and high rendition. After transcoding, ConceptShare will test the user connection and surface the rendition file most applicable to the available bandwidth.

  • Note: If the ingested file does not meet the requirements for a high rendition proxy, ConceptShare will only transcode a low and medium rendition proxy. If the ingested file does not meet the requirements for a medium rendition proxy, ConceptShare will only transcode a low rendition proxy.

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. Below are the current proxy requirements for ConceptShare.
