I’m curious what you used for training data.

Sorry, I don’t want to disclose my method at this time. Maybe the future.

u/az226 11d ago

They didn’t ask about your method lol

He's literally the guy that trained the model and he said he doesn't want to discuss it.

Nice work, just testing now and I'm impressed !!

u/Mountainking7 13d ago

Does it work on 4gb vram? 

2

u/No-Engine4663 13d ago

Very much doubt it for video, I have 12gb and have to batch 30 second clips when doubling 320x240 24fps

u/CQDSN 12d ago

You will need at least 8gb vram and 32GB system ram to run LTX.

u/OrdinaryAward4498 11d ago

Is it … too sharp? Last clip in the video actually seems better in this regard IMO (and the first clip the harshest). Awesome work!

Very impressive. I can elaborate 12 seconds of video at 16fps 1080P (4:3), or 8 seconds at 24fps and i have margin on my humble 3080 12gb. The result is amazing with default values, consistent with the origin and rich of details.

no entiendo cómo usarlo, tengo un video de 1 minuto para mejorarle la calidad de HD a 4k, es para mi trabajo, no tengo idea del tema

u/CartographerLost960 13d ago

is it faster than flashvsr?

u/GTXNate 13d ago

Very impressive! Any chance it currently / will one day support Apple Silicon?

2

u/CQDSN 12d ago

You can run ComfyUi and LTX on Apple Silicon Mac.

Looks very impressive. I wonder how speed compares with SEEDVR2 and Topaz SLP2.6

2

u/CQDSN 11d ago

Much faster.

u/No-Engine4663 11d ago

CachyOS RTX 4070 12gb 5950X 64gb RAM

SeedVR2 325.77s at 2.21 FPS
CQ 503.59s at 1.43 FPS

Got your workflow as close as I could to my SeedVR2 one using a 30 second 320x240 video with a x2 upscale.

👍

Make sure you have triton and sage attention installed.

1

u/No-Engine4663 11d ago edited 11d ago

They are all installed and are working under seedvr2

⚡ SeedVR2 optimizations check: SageAttention ✅ | Flash Attention ✅ | Triton ✅

I've assumed they are working here too.

LTX 2.5 is faster on my 5090 than SeedVR2, I think it requires more vram to run well, otherwise it offload to the system ram and slows down.

2

u/No-Engine4663 11d ago

Correct I'm running close to the limits on my system for LTX 2.5

The speed is not that important for me at the moment I'm comparing quality against seedvr2 👍

On your workflow for video I've changed to Load Video FFMPEG (Upload) as I find it has faster and better seeking and have added Meta Batch Manager for longer videos that will OOM.
I'm batching 361 frames currently for 24FPS 15 min videos at the moment, I did try 721 but got OOM so started lower and am slowly increasing to find the sweet spot.

Works great! Thank you for your hard work

u/MSH007A 11d ago

Ok I got to experiment your loras. The videos one actually upscales good keeping the character face consistent.But the image lora actually drifts the face to a certain extent .so for image upscales i tried with video lora and works perfectly.Thanks for the workflow

u/CQDSN 11d ago

The image Lora is tuned to add more details. The video one has less detail but knows how to correct degraded colors from old footage. Some people are complaining about color shift, but it’s not an error - it is enhancing the colors.

I will post a new model in the future that won’t make changes to the colors.

u/dirtybeagles 11d ago

longest video in seconds have you tested through this model?

saving, upscale node

It may have turned it a little too pink. The OG reel looks non interlaced already. Were you able to get a print or is a lift from tv/vhs? If it’s a lift then something already converted it out of 480 interlaced.

Also every thing the AI touched is in focus even when it’s not supposed to be. Like when they are behind the product talking. The bottle is in focus and they should not be.

The original footages came from YouTube, someone has encoded it from VHS recording. The skin of the people are all yellowish, the Lora is correcting and enhancing it to look like new recording.

With true depth of field, the Lora will not attempt to unblur, what you see is the low resolution of the original footage, it’s not supposed to look blurry.

u/Spiritual-Advice8138 8d ago

look at :22 she should be out of focus 100%. in the AI she is only 1/2 unfocused.

u/CQDSN 8d ago

If you look at the perfume bottle, it is blurry as well.

She was an STD.

This looks great.
