Remotion 4.0.543 adds audio meters and OTIO import, HyperFrames locks down previews, and ReCaVSR 4x upscaling lands in ComfyUI

Remotion 4.0.543 (Nov 11). Studio gets audio level meters, a movable playback diagnostics panel and right-click track creation. Two new CLI commands import work without opening Studio. remotion open-timeline import turns an OpenTimelineIO (.otio) edit into an editable composition, copies local media into public/ and lists any timeline features it can't support (--dry-run previews first). remotion canvas-capture import does the same for a Canvas Capture recording. Renders gain chromiumOptions.flags for overriding Chrome flags and a proResBitsPerMacroblock option (128-8192) to trade ProRes file size against quality. The Remotion skills now default to Studio interactivity and use .element.tsx files. There are also dozens of web-renderer and Lambda fixes. Business note: remotion.pro is retired, and company licences are now bought at remotion.dev/pricing.

HyperFrames v0.9.34 and v0.9.35 (Nov 11). Both are mainly security hardening, and worth updating to if you share previews. Helper programs like FFmpeg now run only from where they're installed or a path you set, never from a project folder (and on Windows the working folder is never searched). Preview bundles never include .env files or git data, and a render that references one now stops with an error. Local sharing only answers your own machine, so sharing from Studio inside a container now returns a 403. A new opt-in 'strict variables' mode fails a render if it's given a variable the page doesn't declare. Plugin and media helpers now run the pinned CLI, and .hyperframesignore accepts gitignore-style patterns again.

ReCaVSR in ComfyUI. Latent Spacer (PedroMarinhoDev on GitHub) ported USTC's ReCaVSR, a one-step streaming video super-resolution model built on Wan2.2 TI2V-5B, to native ComfyUI nodes (GPL-3.0 code). It upscales in blocks (21 frames, then 8 at a time) and reuses earlier blocks instead of starting fresh, so a longer clip costs time and disk rather than memory. His numbers: 960x480 to 3840x1920, 149 frames in 36 s on an RTX 4090 (67 s on a 3090) with the int8 file, from 8 GB of VRAM at 1440p, and a full 3:58 clip upscaled 1080p to 4K in about 25 minutes. It isn't the same model as RelayVSR, which shipped natively in ComfyUI v0.45.0 this week, so it's worth comparing the two on your own footage. The port announcement passed 230 likes and nearly 300 bookmarks, and Machine Delusions' explainer is circulating.

Prompt tip: shot-by-shot JSON for Omni 1.2 Flash. MAX (@maxxmalist) posted two side-by-sides where Gemini Omni 1.2 Flash came close to Seedance 2.5 on realism for about $1.04 per clip versus $3.47 (his costs, on his platform). He says he used no motion transfer, just a very detailed prompt describing every movement second by second. His template is a JSON object with: a core description; what to keep from a reference and what to change; subjects (appearance, hair and makeup, wardrobe, expression); environment (location, layout, foreground, background, key objects); visual style (capture look, lighting, palette, texture); and a shots array. Each shot has a time range, composition, camera position and movement, focus, and timed action beats with gaze and physical details. It ends with audio (dialogue with exact words and delivery, ambience, music, SFX, sync), continuity requirements, an ending and an avoid list. Use it for your own scenes and characters. A reference-recreation field is not licence to copy someone else's footage or likeness.

Signals (not hot by our rule): official release notes (Remotion, HyperFrames), and author posts plus community reposts for ReCaVSR and the prompt template. No tracked curator or Trending overlap within 72 hours.

Our take: update HyperFrames today if you preview from containers or share links. Try open-timeline import if your edits start in Resolve or Premiere and finish in Remotion. Run ReCaVSR against RelayVSR on one soft clip before paying for a hosted upscale.
