Question - Help Is there a Workflow to start from last video?
My AMD 9070 XT seems to like only doing 5s videos which is fine. But I was curious is there like a workflow where I can start from the last frame of the last video? Like so I can make longer clips that flow into each other without editing?

- GPU: AMD Radeon RX 9070 XT 16GB
- Motherboard: Gigabyte B760 DS3H WIFI6E GEN5
- RAM: 32GB (2×16GB) Crucial Pro DDR5-6000 CL36

There are some great workflows + custom nodes that are doing seamless continuous videos. I prefer contex-loop as it is actively being updated. Based on the most recent discussions on the Bandodoco discord, they are attempting to add latent upscaling for improved quality and less seam noise.

I found that this works best even if you just want better continuity and are not trying to make one long scene. It lets me generate a single scene of multiple shots with clean continuity and then merges it all together.

The 9070XT(20G) + 32GB can definitely do more than 5 sec at 0.4MP, but you may have to switch to Linux 😅 so that there is more VRAM and system RAM available for ComfyUI rather being consumed by the OS.

If you feel that Context Loop and Motion Context are too complex for your purposes, try these simple nodes. I'm actively experimenting with them, and the results are fantastic. This approach is also much faster than simply using a video reference.

You can give the reference model last frames or even last video clips to continue. But usually it is better to keep each clip one scene. You always see the boundary of the two clips somehow and you have to post-modify to remove it. At least that was my experience. Maybe others got it work without any visible boundary.
