On November 1 a change landed in ComfyUI's code that looks small on paper but is big for anyone who edits: ComfyUI saves videos in ProRes, as .mov files, straight from the Save Video node, with no extra nodes. If you work with AI-generated video you know the next step well: the MP4 comes out of ComfyUI, you bring it into DaVinci Resolve, Premiere or After Effects, and that's where the compromises start. Heavy compression, colors that turn muddy when you grade them, a timeline that stutters. Until now, to get an "edit-ready" file you needed a community node pack or a separate conversion.
Here's how we see it. We've been working with generative AI since 2024 and today we use ComfyUI on a perfectly ordinary 12 GB RTX 3060, but our trade is still motion graphics: for us a generated video is "footage" to grade, composite and edit, not a finished product. That's why a format designed for post-production matters more than a new model. A word of caution, though: the feature has only just arrived, it's not in an official release yet and it already has a small problem with older workflows. Here's what it really does, checked against the code, and when it's worth using.

What changes with ProRes in ComfyUI?
The video comes out of ComfyUI already ready for editing. ProRes is an "intraframe" codec (each frame is compressed on its own, without depending on its neighbors) created by Apple and used in post-production for years: it's much heavier than an MP4, but it plays smoothly in the timeline and holds up much better to color grading and compositing.
In the Save Video node the format menu now also offers mov, alongside mp4, mkv and webm, and prores appears among the codecs. ProRes can be saved as MOV or MKV; if you leave the format on "auto" and choose ProRes, ComfyUI picks MOV by itself. In the code we verified two profiles:
- ProRes 4444: the default choice, with full-resolution color; if the video has an alpha channel (transparency) it keeps it at 16 bit.
- ProRes 422 HQ: you get it by choosing 4:2:2 subsampling in the Create Video node; lighter files, still master quality for most jobs.
ProRes in ComfyUI works at 10 bit: if you ask for 8 bit, the program saves at 10 anyway and flags it with a warning in the console. If you've already read about 16-bit EXR files in ComfyUI 0.39 and the LogC3 and ACEScct color spaces, the picture is clear: piece by piece, ComfyUI is becoming a real video pipeline tool.
4:4:4, 4:2:2 or 4:2:0: what to choose in Create Video?
For regular editing 4:2:2 is enough; for green screen, masks and heavy compositing 4:4:4 is better. The Create Video node, the one that turns an image sequence into a video, has a new chroma_subsampling menu with four options: auto, 444, 422 and 420.
Put simply, "chroma subsampling" tells you how much color information is kept compared to brightness. With 4:4:4 color is at full resolution; with 4:2:2 it's halved horizontally; with 4:2:0, the one used by regular MP4s, it's halved horizontally and vertically. The eye barely notices, but chroma keys and masks do: edges become "stair-stepped". On "auto" ComfyUI uses the codec's typical choice, that is 4:4:4 for ProRes and 4:2:0 for H.264 and AV1. ProRes doesn't support 4:2:0: if you ask for it, the program switches to the closest supported value and writes it in the console.
The same node still has the color depth options (auto, 8 or 10 bit) and color space options (sRGB, HDR and HDR PQ), useful together with the NVIDIA nodes for HDR in ComfyUI.
How big are ProRes files?
Very big, and that's the price you pay. According to Apple's white paper, in Full HD at 29.97 frames per second ProRes 422 HQ runs at around 220 megabits per second and 4444 at around 330: one minute of 4444 exceeds 2 GB. A good-quality H.264 MP4 of the same clip is a small fraction of that.
For AI clips, which usually last a few seconds, it's not a problem. It becomes one if you generate in batches or upscale to 4K: in that case keep ProRes only for final versions and use MP4 for tests. A practical tip: ProRes files don't play in the browser, so the preview inside ComfyUI might not work. Check them with VLC or directly in your editing software.
How do you enable ProRes in ComfyUI right now?
For now you need the development version, or you have to wait for the next official release. The change was merged into the main branch (master) on November 1, but the latest published release is still 0.43.2 from October 30. If you installed ComfyUI from Git you can update to the master branch; if you use the desktop app or the "stable" portable package you'll have to wait. If you're not sure which version you have, our beginner's guide to ComfyUI explains the differences between installations.
There's also an already reported bug. On November 2 a user wrote under the change that older workflows using Create Video break, because the new menu shifts the field values; a fix is already open on ComfyUI's GitHub, not yet merged as we write. Our advice: if you have projects in progress, wait for the official release. If you want to try it right away, do it on a separate installation.
And if you need ProRes today, in the stable version? Community nodes have existed for a while, for example ComfyUI-ResolveVideoExport, which saves in ProRes 422 HQ, 422, LT and DNxHR. The difference is that native support needs no extra installs and will stay up to date with ComfyUI.
Try it now
As soon as ProRes reaches your version, try this flow with a generated clip, for example with one of the models in our guide to AI video models in ComfyUI:
- Connect the frames decoded by the VAE to the Create Video node.
- In Create Video set chroma_subsampling to 422 for editing, or 444 if you'll do chroma keying or compositing; bit_depth to 10.
- In the Save Video node choose the mov format: the codec switches to ProRes by itself.
- Run the workflow and check the console: any warnings about bits or subsampling tell you what ComfyUI changed.
- Drag the .mov into DaVinci Resolve, Premiere or After Effects and try pushing the color grade: that's where you see the difference compared to MP4.
For quick tests, on the other hand, stick with H.264 MP4: ProRes only for the versions that actually go on the timeline.

Frequently asked questions
Does the free DaVinci Resolve read ProRes on Windows?
Yes, Resolve reads ProRes files in the free version on Windows too, and it's actually one of the most convenient formats to import. Exact support depends on your Resolve version, so if a file won't open, check the format list on Blackmagic's website.
Does ComfyUI's ProRes save transparency?
The code allows for it: with the 4444 profile, if the video contains an alpha channel, ComfyUI saves it at 16 bit. The Create Video node, however, doesn't yet have a dedicated mask input, so for transparent videos today you're still better off with a community node or a PNG or EXR sequence.
Do you need a powerful graphics card to save in ProRes?
No. ProRes encoding is done by the CPU, so it doesn't use video memory. The card matters for generating the video, not for saving it. If you're considering an upgrade, our guide to graphics cards for AI explains what you really need for video models.
ProRes or an EXR image sequence?
It depends on the job. EXR, up to 16 bit in ComfyUI, is the best for compositing and extreme color grading, but it creates thousands of files. ProRes is a single 10-bit file, handy for editing and for handing the work to a client or a colleague. For promotional videos, ProRes 422 HQ is almost always enough.
