    Another great workflow, this works very well. It's easy to use and creates a nice smooth merge with no visible transition as far as I can tell.

    I don't appear to get any transitions, Its processing without errors but it just results in a combined video with just a hard cut edit where it should transition.

    Are there any other instructions for this please?

    it's not a transition tool. you make a video then capture the end frame of the video, then make a new video using that endframe as the start frame for the new video in img to vid, then you merge the two files for a longer video. it can help simplify your directions. eg, maybe you are doing a car chase and the car turns left, then right, then crashing. instead of hoping for a satisfactory output from one prompt and waiting ages for a bad video, you can start your video with just 20 frames and a simple prompt "a car racing through a city street turns left". if you don't like the output, you only waited 20 frames. if you do like the output, then you take the end frame from that video, put it into img to vid and new promt "the car racing through the city street turns right", take the end frame from that and then "the car racing through the city street crashes into a dumpster", and merge the videos together.

    This is very useful, but I'm wondering, is there any way to ensure continuation? For example, maybe a face gets obstructed and then in the new video, the face isn't a continuation of the previous video. Is there a way to remind wan 2.1 of what the base object looks like, across multiple videos and obstructions?

    Thank you. This works well and saves a lot of time.

    I notice that it darkens the video slightly. It's not noticeable on one pass, but combining multiple times to one clip is pretty dark. Is it possible to add more inputs to one pass?

    Now that yall mentioned it, it does degrade the quality of the video by darkening or feels like sharpening effect, even after 1 pass. I wanted to stitched 4 clips together and results looks like a style change.

    This WF is simple, yes. But I guess I have to learn another actual video editing software to stitch the clips together. An updated v2 would be nice.
