name: acmmm-supplementary description: Use when organizing the ACM MM (ACM Multimedia) supplementary material due after the paper deadline — deciding what belongs in the 6-8 page body versus the supplement, packaging video/audio/interactive demos that render on a reviewer's machine, keeping all assets anonymous for double-blind tracks, and pointing to code and data.

ACM MM Supplementary Material

Use this to plan the ACM Multimedia supplement, which has its own deadline after the paper (in 2026, April 8 versus the April 1 paper deadline). For a multimedia paper the supplement is not an afterthought — it is where the video, audio, and interactive evidence lives.

Body vs. supplement split

The 6–8 page sigconf body carries the argument; the supplement carries what the argument rests on but cannot fit.

| Content | Body | Supplement | |---|---|---| | Core claim, main results table, teaser | Yes | — | | The two or three decisive media examples | Yes (stills/short) | Full clips | | Extra qualitative media across conditions | — | Yes | | Full user-study protocol and per-rater data | Summary only | Yes | | Hyperparameters, extra ablations, proofs | Pointer only | Yes | | Code / data pointers | Named | Yes |

A reviewer must be able to follow the body without the supplement; the supplement then confirms rather than completes the argument.

Packaging media that actually plays

The single most common ACM MM supplement failure is media a reviewer cannot open.

video:  H.264/MP4, standard resolution, plays in a browser/VLC; no exotic codec
audio:  WAV or MP3; label each clip with the claim it supports
demo:   if interactive, provide a recorded fallback video — do not assume the reviewer runs it
size:   keep within the cycle's stated limit; compress rather than omit evidence
index:  a short README mapping each file to the paper claim/figure it supports

Anonymity for double-blind tracks

• Strip author names from filenames, EXIF/media metadata, and any on-screen watermark or slate.
• Remove identifying voices/faces of the authors from demo videos where they would reveal identity, or note that they are incidental.
• Route dataset and code links through an anonymous mirror; a personal or lab URL is a leak.
• The Reproducibility, Open Source Software, and Dataset tracks are single-blind and do not need this — but the main track and Brave New Ideas do.

Make the supplement legible

• Open with a one-paragraph README: what is here, and which paper claim each file supports.
• Order files to follow the paper's sections, not upload order.
• Caption every clip; an unlabeled video is not evidence a reviewer can use.

What reviewers actually open

Reviewers are time-pressed and will not download a 2 GB archive or install a codec. Design for a skim:

• Lead the index with the two or three clips that decide the paper, labeled by claim.
• Keep individual files small enough to stream; compress rather than omit.
• Never make the argument depend on a file the reviewer has to run or build — provide a recorded fallback for any interactive demo.

Format and codec table

| Asset | Safe choice | Avoid | |---|---|---| | Video | H.264/MP4, standard resolution | Exotic/proprietary codecs, 4K walls of clips | | Audio | WAV or MP3, labeled | Unlabeled waveforms, lossless dumps for size's sake | | Interactive demo | Recorded MP4 fallback + optional code | Assuming the reviewer runs your app | | Appendix | PDF, same template family | A zip of loose screenshots |

Timing against the paper deadline

The supplement has its own, later deadline (April 8 vs. April 1 in 2026), which is a chance and a trap: do not defer all media to that week, because rendering, compressing, and anonymizing a video library takes longer than expected. Freeze the decisive clips with the paper, and use the extra days for the confirmatory extras, not the core evidence.

Pre-submission checklist

• Every media file opens with common open-source players.
• The index maps each file to a specific figure, table, or claim.
• No author identity in any filename, metadata, watermark, or link (double-blind tracks).
• The body still stands alone if the supplement were removed.
• Total size is within the current cycle's stated cap (待核实 each year).

Output format

[Split] body self-contained / body depends on supplement
[Media playability] all files open / risky: <list>
[Anonymity] clean / leaks: <list>
[Index] each file mapped to a claim / unlabeled: <list>
[Size] within cap / over
[Top fixes] <ordered before the supplement deadline>
