Node Video Combine (VideoHelperSuite) di ComfyUI

Video Combine turns an IMAGE batch of frames into an MP4, WebM, GIF or image sequence at a chosen frame rate, with optional audio, loop count and ping-pong, the standard output node for every video workflow.

Apa yang dilakukan Video Combine (VideoHelperSuite)

VideoHelperSuite (VHS) by Kosinkadink provides the loading and saving nodes that video workflows share. Video Combine takes the decoded frames, a frame_rate and a format (image/gif, image/webp, video/h264-mp4, video/h265-mp4, video/webm, video/ProRes and more via ffmpeg), writes the file to the output folder and shows a playable preview in the node. Options add audio from Load Audio, set a CRF quality, pingpong (play forwards then backwards) and save_output off for temporary previews.
The workflow JSON is embedded in the file metadata when the format allows it, so an MP4 can be dragged back into ComfyUI like a PNG. Load Video (Upload) is the matching input node: it decodes a video into frames with frame_load_cap, skip_first_frames and select_every_nth, and can downscale on load.

BitVector menjalankan workflow ComfyUI siap pakai di GPU miliknya sendiri. Tanpa instalasi, tanpa node hilang, tanpa kotak merah. Buka di ponsel atau laptop dan hasilkan dalam semenit.

Cara menggunakan Video Combine (VideoHelperSuite)

  1. Install ComfyUI-VideoHelperSuite from Manager; ffmpeg is bundled or found on PATH.
  2. Connect the IMAGE batch from VAE Decode to images.
  3. Set frame_rate to match the model (16 for Wan 2.x), format video/h264-mp4, crf 19.
  4. Queue; the video plays in the node and lands in ComfyUI/output.
  5. Add Load Audio and connect it to audio for a soundtrack, or use pingpong for a seamless loop.

Pengaturan dan tips

  • h264 with yuv420p is the compatible choice for sharing; webm/vp9 is smaller.
  • For GIFs, keep 512 px and 8-12 fps or the file gets huge.
  • Interpolate frames with RIFE VFI (Frame Interpolation pack) before Video Combine for smooth 24-32 fps.
  • Wan 2.1 outputs 81 frames at 16 fps (5 s); match frame_rate exactly to keep real-time speed.
  • Drag the MP4 into ComfyUI to restore the workflow.

Pemecahan masalah Video Combine (VideoHelperSuite)

Video formats are missing, only gif/webp are listed

Mengapa terjadi
ffmpeg was not found; VHS lists video formats only when ffmpeg is available.

Cara memperbaikinya
Install ffmpeg (imageio-ffmpeg pip package or a system binary on PATH) and restart ComfyUI.

Playback is too fast or too slow

Mengapa terjadi
frame_rate does not match the frames the model produced.

Cara memperbaikinya
Use the native rate: 8 for AnimateDiff v2, 16 for Wan, 24 for Hunyuan and LTX; interpolate if you want more.

The preview shows one frame or a still image

Mengapa terjadi
The IMAGE input is a single frame (batch of 1), for example from a sampler without a video latent.

Cara memperbaikinya
Check the latent node: Empty Hunyuan Latent Video / Wan latents need a length above 1; decode the batch, not a single frame.

Error: height not divisible by 2 (h264)

Mengapa terjadi
yuv420p needs even dimensions.

Cara memperbaikinya
Render at even sizes (multiples of 8 or 16), or add an Upscale Image node to an even size before Video Combine.

Pertanyaan tentang Video Combine (VideoHelperSuite)

Can I save frames as PNG sequence?

Yes, choose image/png or connect the frames to Save Image, which writes numbered PNGs.

How do I add sound?

Load Audio (core) or VHS Load Audio, connected to the audio input. The audio is trimmed to the video length.

Where is the file?

ComfyUI/output with the filename_prefix; save_output off writes to temp.

Node terkait

AnimateDiff Loader (Evolved)
ComfyUI-AnimateDiff-Evolved
AnimateDiff Loader adds a motion module to an SD 1.5 or SDXL model so a batch of latents is rendered as coherent animation frames, the classic route to short clips from text with Stable Diffusion.
WanImageToVideo and Wan 2.x video nodes
ComfyUI core
WanImageToVideo builds the conditioning and the empty video latent for a Wan 2.1/2.2 image-to-video render from a start image, a CLIP Vision embedding and the frame count; the surrounding graph uses Load Diffusion Model, Load CLIP, Load VAE and KSampler.
Save Image
ComfyUI core
Save Image writes the IMAGE tensor to ComfyUI/output as a PNG, with the whole workflow embedded in the file metadata so the picture can be dragged back into ComfyUI to restore the graph.
VAE Decode
ComfyUI core
VAE Decode converts the sampled LATENT into a pixel IMAGE with the VAE; VAE Decode (Tiled) does the same in tiles for very large images.
Load Video (Upload) (VideoHelperSuite)
ComfyUI-VideoHelperSuite
Load Video (Upload) decodes a video file into an IMAGE batch of frames (with frame cap, skip and every-nth options) plus the audio and frame count, the input node for video-to-video and frame-by-frame processing.

Node ComfyUI lainnya

CLIP Text Encode (Prompt)
ComfyUI core
CLIP Text Encode turns a text prompt into CONDITIONING using the model text encoder. One node holds the positive prompt, a second one the negative prompt.
ComfyUI Manager
ComfyUI-Manager
ComfyUI Manager is the extension that installs, updates and fixes custom node packs and models from inside the interface, resolves missing nodes in imported workflows and snapshots your setup.
KSampler
ComfyUI core
KSampler runs the denoising loop: it takes the model, prompts and a latent and produces the finished latent image, controlled by seed, steps, cfg, sampler, scheduler and denoise.
Load Checkpoint
ComfyUI core
Load Checkpoint (CheckpointLoaderSimple) opens a .safetensors or .ckpt model file and hands out the three parts every workflow needs: the diffusion MODEL, the CLIP text encoder and the VAE.
Empty Latent Image
ComfyUI core
Empty Latent Image creates the blank latent canvas (width, height, batch_size) that text-to-image sampling starts from; dimensions must be multiples of 8 and match the model family.
Load Image
ComfyUI core
Load Image reads a picture from the ComfyUI input folder (or an upload) and outputs an IMAGE tensor plus a MASK taken from the alpha channel, the starting point for img2img, inpainting, ControlNet and IP-Adapter graphs.
