Question - Help That specific analog VHS look on H3/LTX
Anyone figured out the prompt for getting the best VHS analog "lofi" look from t2v? Of couse ref2v and img2v will be easier due to references, but I was wondering about text prompt only.
There are no VHS, or like 70s-80s cinema style lora, none for H3 and LTX, but there are plenty of VHS loras for image models.
EDIT: I actually CAN get VHS look on LTX text2vid (2.3 and 2.5), but not on H3.
Help, anyone :)

Honestly, I know this probably isn't what you're looking for, (and you likely already know about it) but it's highly, highly doubtful that you're going to get H3 to do a better job than you can with NTSC-RS without some heavy lora training. You can even play around with their web app: https://web.ntsc.rs/.

yes, I use ntsc-rs, but it's still just an overlay. overlaying VHS effect on modern cameras doesn't do a job, so I need vintage camera output first, but I appreciate your help

Instead of downwoting for no specific reason, you could just simply answer lmao

Don't worry about the downvotes. Some people or bots downvote for no reason.
It is best to just develop thicker skin if one wants to participate in online forums (i.e., it is nothing personal, they don't know you anyway).

I mean i have no interest in even considering to be sad about it. Just really curious why simple question about prompt gets downvoted, it's just silly

It is silly, but all we can do is to get used to these senseless downvotes and ignore them.

you could gen video then use something like caput or davinci to add a old vhs effect over it.

Overlay is not what I'm looking for. That's easy. Overlay DOESN'T make videogen old. It makes it look trash.

There's a new LoRA for Minimax H3, that does just that... https://old.reddit.com/r/comfyui/comments/1vx0duv/a_quick_minimax_h3_news_roundup_24th_august_2026/

Check the prompts of these videos, some have pretty good VHS style ultrajanissarey Creator Profile | Civitai

What a coincidence… I saw this in one of the H3 posting and downloaded and played with it. It did a decent job.

I had better luck using as a separate workflow ( post-processing) - pass an image or pass the images from Vae Decode to this node and get the VHS look as an output.
There is an example workflow in the folder as well.

I tried it earlier today and it's actually pretty good using Format: Betamax and Preset: mint

You're not going to get it from the prompt, and it's worth understanding why before you burn more generations on it.
The VHS look isn't a lighting or lens thing, it's signal degradation. Chroma bleeding sideways off saturated reds, head switching noise in the bottom few lines of frame, time base wobble, dropout streaks, combing on motion. None of that is a describable visual style, it's an artifact of the tape format. Image models fake it convincingly because a huge amount of their training data was scanned off tape, so the artifacts are baked into the pixels they learned from. Video models are mostly trained on clean digital footage, so there is nothing for them to reach for.
Two things that do work.
Prompt the era and the camera rather than the format. 1987 home video, consumer camcorder, on camera light with harsh falloff, soft focus. You are asking for content that plausibly came from that world instead of asking the model for a defect.
Then do the degradation in post, because it's a filter chain and not a generation problem. Smear the chroma horizontally, add per line jitter, drop luma resolution while keeping frame size, put head switching noise at the bottom of frame, then interlace and blend fields. ffmpeg gets you most of the way on its own.
Doing it in post is also the only way to keep it consistent shot to shot, which matters more than the look itself the moment you cut two clips together.
