[Update] ComfyUI VACE Video Joiner v2.5 – Seamless loops, reduced RAM usage on assembly

Github | CivitAI

Point this workflow at a directory of clips and it will automatically stitch them together, fixing awkward motion and transition artifacts. At each seam, VACE generates new frames guided by context on both sides, replacing the seam with motion that flows naturally between the clips. How many context frames and generated frames are used is configurable. The workflow is designed to work well with a few clips or with dozens.

Input clips can come from anywhere: Wan, LTX-2, phone footage, stock video, whatever you have. The workflow runs with either Wan 2.1 VACE or Wan 2.2 Fun VACE.

v2.5 Updates

• Seamless Loops – Enable the Make Loop toggle and the workflow will generate a smooth transition between your final input video and the first one, allowing the video to be played on a loop.
• Much lower RAM usage during final assembly – Enabled by default, VideoHelperSuite’s Meta Batch Manager drastically reduces the amount of system RAM consumed while concatenating frames. If you were running out of RAM on the final step because you were joining hundreds or thousands of frames, that shouldn’t be a problem any more.
• Note – If you’re upgrading from a previous version, be sure to upgrade the Wan VACE Prep node package too. This version of the workflow requires node v1.0.12 or higher.
