ACM MM Topic Selection

Use this before writing. ACM MM is strongest for work that treats more than one medium at once — vision, audio/speech, language, sensor, interaction — or that advances the systems that transport, index, and render media. The core test is whether the contribution lives at a seam between media.

Fit test

• Prefer ACM MM when the contribution is cross-modal integration (fusion, alignment, cross-modal retrieval/generation), a media-systems advance (streaming, QoE, transport), or a human-centric media result (emotion, aesthetics, engagement, art).
• Route to CVPR/ICCV/ECCV if the contribution is a pure computer-vision claim — a better detector, segmenter, or backbone with no essential second modality.
• Route to ACL/EMNLP if it is a pure language claim, and to NeurIPS/ICLR if it is a general ML method whose multimedia setting is incidental.
• Route to ICMR for retrieval-centric work that is more IR than multimedia systems, to MMSys for systems/networking-heavy media delivery, and to the ACM TOMM journal when the work needs journal-length treatment.
• Confirm the argument can be made convincing in a 6–8 page sigconf body.

Fit signal table

Signal in the project	ACM MM reading
Two or more modalities that must interact for the result to hold	Core fit — the house genre
A reusable media system, framework, or dataset the community adopts	Core fit (Open Source / Dataset tracks)
Subjective quality / emotion / engagement measured with a user study	Core fit (human-centric areas)
A single-modality benchmark win (vision-only, text-only)	Better at CVPR/ICCV or ACL
Retrieval accuracy with no systems or cross-modal novelty	ICMR or SIGIR
Media delivery / networking with little content modeling	MMSys

Picking the thematic area

The main track is split into thematic areas (Multimodal Fusion; Generative and Foundation Models; Search and Recommendation; Emotional and Social Signals; Art and Culture; Systems; Transport and Delivery; Responsible Multimedia; and more). The area is not cosmetic — it selects your reviewers. Name the primary area honestly; if the paper genuinely spans two, pick the one whose reviewers can best judge the contribution, not the application.

Vignette: where an audio-visual model goes

A project fuses lip motion and speech to improve transcription in noise. ACM MM reading: strong fit — the gain exists only because two modalities correct each other, which is the Multimodal-Fusion heartland. Strip the audio and keep a visual speech-recognition benchmark, and the same project reads as a CVPR paper; strip the video and tune a language model on the transcripts, and it becomes an ACL/speech paper. The multimedia contribution is the correction between streams.

Routing within ACM MM

Deciding it is an ACM MM paper is only half the choice; the track shapes everything after.

The project's center of gravity	Track within ACM MM
A method paper with cross-modal results	Main track (pick a thematic area)
A bold vision / new direction, evidence lighter	Brave New Ideas
A shared task entry with a competitive result	Multimedia Grand Challenge
A reusable, documented software system	Open Source Software Competition
A new dataset or benchmark	Dataset track
A rebuild of prior published results	Reproducibility track

The tracks differ in blinding and in what reviewers reward, so a strong-but-early idea does better in Brave New Ideas than as a thin main-track method paper, and a great system does better in the Open Source competition than buried as a main-track artifact.

The single-modality trap

The most common misroute is a single-modality paper wearing a multimedia costume: audio or text is bolted on but never shown to matter. If a leave-one-modality-out ablation would leave the result essentially unchanged, the paper is not cross-modal, and an ACM MM reviewer will say so. Either make the second modality load-bearing or route the paper to its true home venue before writing — retrofitting multimedia framing onto a vision or NLP result rarely survives review.

Sharpening moves before committing

• Name the cross-modal or systems primitive: the fusion mechanism, the alignment objective, the delivery scheme, or the perceptual measure. If none exists, the ACM MM framing does not either.
• Decide the track early — main vs. Brave New Ideas (vision paper), Open Source Software, Dataset, or Reproducibility — because each has a different format and blinding rule.
• If the payoff is subjective, plan a user study now; ACM MM reviewers expect perceptual claims to be measured, not asserted.
• Thematic-area lists drift between cycles; scan the current Topics of Interest before final routing.
