Report: June 2024 Plugfest

The IMF UG held a plugfest on June 26, 2024 at Universal Studios in Los Angeles (USA), with remote participation through shared cloud storage and virtual breakout sessions. The plugfest gathered more than 20 participants from the content creator, user, and implementer communities.

Throughout the day, participants created, exchanged, and consumed IMF content. Cross-checking IMF content between implementations ensures the standard is supported and helps reveal potential improvements to both implementations and the standard.

This report summarizes the use cases studied during the plugfest.

High Throughput JPEG 2000 (HTJ2K)

HTJ2K significantly improves the encoding and decoding speed of JPEG 2000, reducing processing costs and allowing real time playback on consumer desktops and laptops. This use case involved QC and playback of compositions that used HTJ2K-encoded video.

Use case and source content provided by NBCUniversal and The Walt Disney Studios.

Photon

Photon is an open-source library for parsing, interpreting and validating constituent files that make an Interoperable Master Package (IMP). These include: 

Currently, Photon provides support for IMF Application #2E (SMPTE ST 2067-21) and Application #5 ACES (SMPTE ST 2067-50), and the Immersive Audio Bitstream (IAB) Plug-in (SMPTE ST 2067-201).

For this plugfest, a pull request against Photon was created by Pierre-Anthony Lemieux that included additional checks for HTJ2K codestream header metadata. This build was used for the validation of the plugfest content.

Test content created with Colorfront, MTI, Blackmagic Design, and Telestream technologies.

No-Proxy Streaming

Using no-proxy HTJ2K MXF JavaScript player, files are read from an AWS S3 bucket with pre-signed URLs. The MXFs are played directly in the browser using JavaScript, there is no proxy involved. If connection is limited, it will fetch only the low-resolution wavelet information and show a low-resolution image during playback. Pausing playback will fetch all the data for that frame. For lossless IMFs, this is the lossless data, for lossy IMFs this is the high quality you would experience from a normal full decode.

Traditional IMF J2K part 1 encoding uses the CPRL progression order, for this player to work the no-proxy player needs HTJ2K with RPCL progression order. The no-proxy player is currently limited to 4:4:4 sources. While the 4:2:2 source will decode, it will only show the actual Y, and half-vertical with Cb and Cr that is associated with 4:2:2.

Observations

The goal of this plugfest was to focus on creation and interchange of HTJ2K within IMF. The focus has increasingly pointed to the need for the community to have consistent ways of validating content.

  1. The plugfest showed that the lack of a common validation tool and/or test vectors introduces friction. The IMFUG should consider an effort to support a common validation strategy and/or toolset that includes codestream analysis.
  2. HTJ2K no-proxy streaming functions as expected when source materials are encoded with RPCL progression order. Some HTJ2K content was still found to have the CPRL and LRCP progression orders which did not work.
  3. Colorfront enhanced their validation toolset to include codestream inspection with comparison of the essence and metadata values. This helped the plugfest identify additional issues with submitted packages.
  4. Although most solutions have the ability to create HTJ2K IMF, errors were still present that included:
    • CPRL and LRCP progression order
    • Missing TLM marker
    • Incorrect schema definition in CPL
    • Invalid HTJ2K tile part count
    • MXF essence and metadata values not matching

Future plugfests

We are already working on future plugfests, possibly as early as November 2024. In the meantime, testing should never stop, and the content used during the plugfest remains available to all IMF UG members.

Join the UG today to get access to past plugfest content and help the community plan future plugfests!

Report: IMF UG Plugfest (December 2023)

The IMF UG held a hybrid plugfest on December 13 and 14, 2023, with physical locations in Los Angeles (USA) and Cologne (Germany), and remote participation through shared cloud storage, virtual breakout sessions and instant messaging. The plugfest, the first since February 2020, gathered more than 50 participants from the content creator, user, and implementer communities.

Over 2 days, participants created, exchanged, and consumed IMF content. Cross-checking IMF content between implementations ensures the standard is supported and helps reveal potential improvements to both implementations and the standard.

This report summarizes the use cases studied during the plugfest.

Lossless conversion from MOV to IMF

IMF Application ProRes (SMPTE RDD 45) enables lossless conversion of existing ProRes QuickTime files to IMF. For this use case, the ProRes video contained in MOV files was rewrapped into IMF Compositions without any decoding and re-encoding, demonstrating lossless conversion and eliminating generation losses.

Use case and source content provided by BBC.

Deduplication

Deduplication refers to the reuse of identical essence in multi-version titles, also known as “versioning”. A typical ProRes workflow produces one flat MOV file for every version of a title, even if only a few frames differ between those versions. For this use case, five MOV files were provided: one was identified as the source version and the others as derived versions with different inserts, cuts and pre-rolls. From these five flat files, five IMF composition playlists, each corresponding to one of the versions, and a collection of video components were created. One of the components contained all the frames of the source version while the others contained only inserts and pre-rolls. By allowing portions of the source version components to be reused across composition playlists, IMF achieved a 75% reduction in storage compared to the five flat files.

Use case and source content provided by RTL.

Immersive Audio Bitstream (IAB)

IAB is a mature format for encoding immersive sound fields as a collection of audio channels and audio objects. This use case involved successful QC and playback of an IMF composition whose audio essence consisted solely of IAB essence and did not contain multichannel audio essence.

Use case and source content provided by Sony Pictures Entertainment.

Audio Definition Model (ADM)

S-ADM (Serialized Audio Definition Model) and ADM (Audio Definition Model) are recent ITU-R Recommendations for interactive and immersive audio applications associating metadata with audio essence. The use case involved creating IMF compositions starting from audio essence with S-ADM and ADM metadata wrapped in MXF files.

Use case and source content provided by Fraunhofer IIS.

High Throughput JPEG 2000 (HTJ2K)

HTJ2K significantly improves the encoding and decoding speed of JPEG 2000, reducing processing costs and allowing real time playback on consumer desktops and laptops. This use case involved QC and playback of compositions that used HTJ2K-encoded video.

Use case and source content provided by Warner Bros Discovery, Sony Pictures Entertainment, NBC Universal, and Walt Disney Studios.

ISXD

Carrying metadata as a separate component allows its addition, modification, and removal without having to modify associated essence components. This use case involved QC and playback of a composition that contained Dolby Vision metadata stored in a separate track file conforming to the Isochronous Stream of XML Documents (ISXD) plug-in.

Use case and source content provided by Walt Disney Studios.

Stereoscopic 3D

Stereoscopic 3D video has been a core, but infrequently exercised, capability of IMF since its inception. This use case involved QC and playback of a Stereoscopic 3D composition.

Use case and source content provided by Walt Disney Studios.

Lossless To Lossy Transcode

IMF Application 2E supports both lossless and lossy JPEG 2000 video essence. This use case involved the transcoding of lossless JPEG 2000 (Main level 7 Sublevel 0) compositions (HDR and SDR) to lossy JPEG 2000 (Main level 6 Sublevel 4 and Main level 6 Sublevel 3) compositions, which were subsequently subjected to QC and playback.

Use case and source content provided by Sony Pictures Entertainment.

Observations

As IMF matures, the focus has increasingly turned to operational improvements and incremental upgrades.

  • The plugfest highlighted the importance of a common validation strategy: different versions of the widely used Photon OSS validator performed differently when faced with newer use cases.
  • The plugfest was an opportunity to experiment with new capabilities such as S-ADM and ADM, which are expected to be leading topics of future plugfests.
  • Support for IMF across proprietary and open-source tools can always be improved. There is, for example, an opportunity to expand support for IMF beyond multichannel audio and monoscopic video in the popular open-source FFMPEG toolkit.

Future plugfests

We are already working on future plugfests. In the meantime, testing should never stop, and the content used during the plugfest remains available to all IMF UG members.

Join the UG today to get access to past plugfest content and help the community plan future plugfests!
