BytePlus Video Enhancement Pro

Video upscaling is the least glamorous job in this whole pack and one of the most useful: you've got a 480p clip - phone footage, a download, an old render - and you want it to look like it was shot at 1080p or 4K. This node runs BytePlus (ByteDance's cloud services arm) video enhancement on Runware's GPUs. Drop in a video, pick a target, and get back the enhanced version without installing a single upscaler.

The "Pro" here is the heavier of BytePlus's two enhancement tiers. The honest difference between Pro and Standard in the node list is thin - the Standard node adds a style preset, Pro doesn't - so Pro is the "just make it better" option and Standard is the "and also tell me the genre of clip" option. Pick by that, not by the name.

The inputs that matter

• video (required, STRING): the source clip, as a UUID or URL.
• resolution: the headline control - 240p up through 1080p, 2k, and 4k, or the default. The tooltip notes it auto-matches your input's aspect ratio, so you don't fight letterboxing.
• settings.bitrate: low / medium / high. This is where quality and file size trade off; crank it for a final asset, keep it medium for drafts.
• fps (gated toggle): flip on to set a target frame rate (15–120). The default leaves the source's fps alone - which is right unless your clip is choppy and you want it smoothed.
• settings.resolutionLimit (gated): caps the short side of the target resolution, scaling proportionally. Useful when you want "bigger, but don't touch my aspect."

Output format (MP4/WEBM/MOV) and quality (default 95) close out the standard block.

One thing worth flagging because it will confuse you the first time: the node's output is typed IMAGE, not VIDEO. The schema says so, even though every widget here describes a video. So wire the output into an image preview or save node rather than expecting a VIDEO socket - that's a known quirk of how Runware's catalog types these enhancement calls, not a broken install.

How it works

Pack-standard: your clip goes up by URL or UUID, BytePlus enhancement runs on the cloud, and the result comes back as a file the pack converts into your graph. No local upscale stack, no Real-ESRGAN tuning, no waiting on a CPU encode. Each run's cost lands on the title bar.

Install and gotchas

Install the pack once - ComfyUI Manager, search Runware - or git clone https://github.com/Runware/ComfyUI-Runware into custom_nodes + pip install -r requirements.txt, restart, and set a Runware API key (Settings → Runware API key, RUNWARE_API_KEY, or runware auth login).

The gotchas: remember the IMAGE-typed output, budget the cost of 4K (it's the priciest preset for a reason), and don't expect enhancement to fix a genuinely broken source - garbage in, cleaned-up garbage out. For "my clip deserves to be sharper than my phone recorded it," this is the zero-friction answer.
