J-cuts and L-cuts with generated audio
Stitched clips read as a slideshow because picture and sound change on the same frame. How to split those edges when the audio came out of the generation.

Reverb is the most common uninvited guest in native audio. The room words that cause it, the exclusion phrasing that works, and what to do with a good take.
Native-audio models place a limited number of sound events per clip. Name two specific, countable sounds and you get both; name six and you get mush.
Native audio invents a new room on every clip, and the cut exposes it. How to hold ambience constant in prompts, and the matching pass to run at assembly.
Some models move the sound when the camera moves, making camera language audible. When that earns the prompt work, and how to check it survives a phone speaker.
Artificial Analysis runs a text-to-video board scoped to output with audio. Arena's board is not scoped that way, and the two rank almost inversely.
Wan 3.0 leads Artificial Analysis' with-audio board and is absent from Arena's top ten. Why a missing model is a roster fact rather than a result.
Native audio is a capability flag, not a language list. A one-generation test for any model, and the rule for generating natively versus dubbing after.
ByteDance's Seedance 2.5 generates 30 seconds of synced audio and video in one pass with up to 30 references. What's new, and how to fake it today.
Most creators reach for a music track when a clip feels empty. Often what it actually needs is a room — build the ambience first and music gets easier.
Native audio wins when sound is caused by what's on screen, and loses when sound is an authored layer. A practical rule for picking the pipeline.
