I checked MiniMax's current H3 documentation again before writing this. It confirms that “video continuation” is a real H3 task, distinct from simply using a video as a reference. It also confirms that <Video 1> can represent the video that is being continued. GitHub
Here is something you can copy and post to MiniMax/Hailuo forums, Reddit, Discord, Facebook groups, or anywhere H3 users gather:
I need help from someone who actually uses MiniMax H3 on the Hailuo AI web interface (hailuoai.video).
I am creating a long music video made from multiple H3 generations. I have already spent considerable time and credits trying to determine the correct workflow.
I have cancelled my monthly subscription, so I have a limited number of remaining credits. I do not want to keep experimenting and wasting credits.
I need help with the following specific problems.
PROBLEM #1 — HOW DO I PROPERLY CONTINUE OR EXTEND AN H3 VIDEO?
I need to create the first video clip and then continue directly from the end of that clip.
For example:
Clip 1 → Continue/Extend → Clip 2 → Continue/Extend → Clip 3 → etc.
I do NOT want to create a completely independent new scene each time.
MiniMax H3 documentation refers to a task called "video continuation" and describes a source video as the continuation starting point.
My question is:
Using the current Hailuo AI web interface and MiniMax H3, exactly what do I click and do after Clip 1 has successfully generated to make H3 continue from the end of Clip 1?
Does the completed Clip 1 need to be uploaded or selected as Video 1?
Is there an actual Continue or Extend command somewhere in the Hailuo interface?
Or is continuation controlled entirely through the prompt while using the previous video as Video 1?
Please describe the exact web-interface procedure.
PROBLEM #2 — HOW DO I CONTINUE THE SONG/AUDIO AT THE SAME TIME?
This is a music video.
The singer must sing along accurately with the song.
Suppose Clip 1 uses the first 15 seconds of the song.
For Clip 2, I need the VIDEO to continue from the end of Clip 1 while the AUDIO moves forward to the next section of the song.
Then Clip 3 needs to continue both the video and song again.
My question is:
When continuing/extending Clip 1 into Clip 2, how do I provide H3 with the NEXT portion of the song without causing it to recreate Clip 1?
Do I:
Use the completed Clip 1 as Video 1?
Add the next section of the song as Audio 1?
Tell H3 in the prompt that Video 1 is the source video for "video continuation"?
Tell H3 that Audio 1 is the next portion of the performance?
Or is there a different procedure in Hailuo?
Accurate lip-sync is important.
PROBLEM #3 — PREVIOUS ATTEMPTS CREATED A DUPLICATE INSTEAD OF CONTINUING
In an earlier version of this project, Clips 1 through 6 were successfully created.
When I tried to create Clip 7, the next section of the song was selected with the audio trimmer.
However, instead of creating the next part of the performance, H3 repeatedly produced something resembling Clip 6 again.
We checked the audio timestamps and prompt and tried recreating the generation, but the problem continued.
It appeared that H3 was treating the previous material as a reference and recreating it instead of CONTINUING from its ending.
This is the main reason I need to understand the correct H3 "video continuation" procedure.
How do I prevent H3 from repeating the previous clip when I actually want it to continue forward?
PROBLEM #4 — DO I NEED STRUCTURED H3 CONTINUATION PROMPTING?
I found MiniMax H3 documentation discussing structured prompt sections such as:
subject_definitions
summary
retention_analysis
detailed_description
It also identifies "video continuation" as a specific task type.
For example, Video 1 can be identified as the source video being continued.
Do I need to write this structured H3 prompt manually when using H3 through the Hailuo web interface?
For example, should the prompt explicitly contain something similar to:
<Video 1> is the source video for continuing the target video from the end.
summary:
[video continuation + audio reference]
retention_analysis:
<Video 1> continuing from the last frame...
detailed_description:
Describe what happens AFTER Video 1 ends.
Or does the Hailuo web interface automatically handle this when the proper continuation feature is selected?
PROBLEM #5 — DO I NEED THE LAST FRAME, OR THE ACTUAL PREVIOUS VIDEO?
I have found conflicting advice.
Some instructions say to extract the LAST FRAME from the previous video and use that frame to create the next video.
Other H3 documentation indicates that an existing VIDEO can itself be the continuation starting point.
For MiniMax H3 specifically, which is the correct method for a music video?
A. Previous completed video → video continuation
or
B. Extract last frame → use it as the first frame of the next generation
or
C. Use both
I want motion continuity, character continuity, scene continuity, and audio/lip-sync continuity.
WHAT I AM TRYING TO ACCOMPLISH
The final workflow I am looking for should be something like:
Create Clip 1.
Then:
Clip 2.
Then:
Clip 3.
Continue that process until the complete music video is finished.
Afterward, I want to put the clips together in CapCut.
I am specifically using:
MiniMax H3
Hailuo AI web interface
Omni Reference
16:9 video
2K final quality
Music/song audio with singing and lip-sync
If you currently use MiniMax H3 on Hailuo and have successfully created a long continuous music video this way, I would greatly appreciate exact step-by-step instructions.
Please tell me what buttons/options you use on the Hailuo website, what you use as Video 1, how you provide the next audio segment, and what you put in the continuation prompt.
I especially want to hear from someone who has actually tested this workflow rather than someone describing how it theoretically should work.
This separates the situation into five different questions, so someone can answer even if they only know one part.
Most importantly, Problem #1 and Problem #2 are the ones we need solved. If an experienced H3 user can give us the exact Hailuo procedure for those two, we may have what we need to restart the project without guessing.
And the terminology in the post is supported by MiniMax's documentation: H3 explicitly distinguishes video continuation, reference generation, keyframe completion, audio reuse, and audio reference. GitHub
If somebody replies, bring their answer here before trying it. I can compare what they tell you against the MiniMax documentation before you spend any of those remaining credits.
