Compare. Listen. Choose.One workflow, several LoRA combinations—and a clearer way to choose the result worth finishing. Prepare short video trials, compare them on the same page, inspect the soundtrack, then carry the winning settings into a full-length render.## Build experiments without juggling tabs- Capture your working ComfyUI video workflow; create a LoRA-free baseline and independent sample cards.- Search installed LoRAs and set each card's switches and strengths. Every card shows its own saved active LoRA names and values.- Use automatic short trials for recognized H3/LTX timing layouts, choose a custom length, or keep the original duration.- Run prepared samples sequentially. Add a third or fourth experiment later: completed takes stay available and are not regenerated.- Start controls sit directly below the cards. Stop after the current test or cancel this test's own job; keep completed results.## Compare picture, motion and soundTake Compare is built into the test page. Review up to four clips with shared playback, frame stepping, linked zoom, timing offsets, notes and marked moments. Each video also has independent play/pause, 0.25x–2x speed and repeat, so you can inspect one take at a time on a single monitor.Finished sample cards have their own players. Live image frames can appear during generation when the workflow sends supported standard ComfyUI previews.Open Audio inspection to load the original soundtrack's mono/stereo waveforms, zoom and seek, and inspect decoded sample peak/RMS levels in dBFS. Choose picture, motion and audio winners separately.## Keep the winnerPrepare a full-length job from a completed sample, then explicitly start it. Or export the winning workflow with its saved settings and restored full duration. Verified mappings export editable UI JSON; dynamic or unverified mappings use a clearly labelled API JSON fallback.Not just H3. The reviewer accepts supported local videos from LTX, other AI generators, cameras and editors. Generation testing requires a working ComfyUI graph with supported loaders/savers and your installed resources. Optional handoffs to Take Mixer, Loop Lab and Final Check are available when those separate tools are installed.## Install and startExtract the entire ZIP. Stop your backend, run START_HERE.cmd, and choose the ComfyUI backend your application actually uses. Restart the entire SwarmUI/ComfyUI backend and refresh the browser. Open a working generation workflow and right-click empty canvas -&gt; Prophetero · Test Bench + Take Compare.Windows installer; English default; EN / HU / DE / FR / ES / IT / PT / PL. Models, LoRAs, Python/ComfyUI, other companion tools and personal videos are not bundled. No paid cloud account is required.## Before downloadingPublic beta 0.4. Supported outputs: SaveVideo and VHS_VideoCombine. LoRA editing supports Power Lora Loader (rgthree), LoraLoader and LoraLoaderModelOnly. Model selection does not convert architectures or fix encoder/VAE compatibility. Automatic shortening depends on recognized timing controls; a short successful test cannot guarantee a full-length render.Review limits: 0.5–120 seconds, 1–60 FPS, up to 8 megapixels and 2 GiB per clip / 6 GiB total; upright square-pixel SDR video and mono/stereo audio. Up to 24 samples/project, four compared at once. Playback proxies leave originals unchanged; source frames are used for paused detail. Waveforms are sample peak/RMS measurements, not LUFS/true-peak mastering or automatic repair. Shared playback is a review aid, not guaranteed frame/sample-locked mastering. Visual/anatomical defects still need your judgement.Isolated browser, audio, workflow-planning and installer tests passed using neutral clips and simulated inference. Real-model coverage remains limited; see the included validation notes.Credits: built for ComfyUI and the user's existing generation ecosystem.
