What is the best workflow for preparing images?

Let's say I have portrait images that are mediocre quality and not 1024x1024. Which of the following is the best workflow:

Workflow A: joycaption,supir 5x upscale with caption,outpaint image sides,downscale to 1024x1024
Workflow B: joycaption,supir 5x upscale with caption,downscale to 1024x1024 with transparent sides
Workflow C: joycaption,supir 5x upscale with caption,downscale to 1024x1024 with black or white sides

Also, I'm unsure which caption type + length I should use with joycaption

EscanorOP•5/17/25, 12:06 AM

And for having square images, for my current dataset, I had used Fooocus to outpaint the sides since the original images were portrait, but would it be acceptable or good to just resize to 1024x1024 and have the sides be black,white or transparent..? Or will that confuse the training?

EscanorOP•5/17/25, 12:06 AM

Sorry for many questions, thank you very much for the help!

FFurkan Gözükara SECourses are you batch size 7?

skyrrr•5/17/25, 8:25 AM

No I mean I'm currently using the 48go config with an L40S and getting around4.8 sec. I have a deadline and would need the training to be twice faster, so I wondered if that was achievable with an H100 SXM. Sorry if I explained myself wrong

ah yes go with h100 it will be faster directly

FFurkan Gözükara SECourses for flux i dont use captions i dont recommend 😄

EscanorOP•5/17/25, 1:21 PM

Well it wasn't for flux specifically, it was to have captions from image to upscale them with SUPIR!

What I'm unsure of is the best workflow to prepare a dataset of mediocre quality to increase its quality...

And also if I can just resize to 1024x1024 a portrait images and just leave the sides transparent

Furkan Gözükara SECourses•5/17/25, 3:15 PM

for supir caption matters

Furkan Gözükara SECourses•5/17/25, 3:15 PM

you can use joy caption

EscanorOP•5/17/25, 3:17 PM

Yeah I am, just wondering if it's better to use "descriptive" caption type or "training" and the caption length

Also hesitant for more specific words. For example, my photo has "snake bites" piercings which is essentially a ring on each side of the bottom lip, but I'm unsure if I should put "snake bites ring piercings" or just like "two lip ring piercings"

EscanorOP•5/17/25, 3:18 PM

I'm literally trying it out right now on a h100 on massed compute right now

no idea you better test

FFurkan Gözükara SECourses no idea you better test

EscanorOP•5/17/25, 3:20 PM

Ok, thank you

Only other thing I'm wondering is this: if I have a portrait image, can I just resize to 1024x1024 images and just leave the sides transparent or white/black or do I absolutely have to outpaint the sides if I want to use this image for training in my dataset?

Thanks!

Furkan Gözükara SECourses•5/17/25, 3:40 PM

you can leave empty transparent

EscanorOP•5/17/25, 3:54 PM

oh really?? Wow.. This will make things so much easier...

I had spent to much time trying to outpaint something decent for the sides with Fooocus..

Damnit lol, glad I asked thank you very much

Hello everyone

I am new to the AI world, started learning around a week ago, and my goal is to create a realistic-looking Instagram influencer with the same face and body (body seems hard but at least face hah). I have a dataset of 70 images, which are all 1024x1024 and good quality I think, and I will be training a lora in Fluxgym because it seems beginner friendly.
I just wanted to ask for your suggestions and advice on a few things. What would you recommend in terms of trains per image, number of epochs, and LoRA rank for this kind of realistic, identity-focused project?

(also thank you very much for all your research and insights @Furkan Gözükara SECourses)

Mmlado Hello everyone 👋 I am new to the AI world, started learning around a week ago, ...

Timson•5/18/25, 10:07 AM

start (and end) with fine tuning, skip LORA step. It's not much harder for beginner, basically same process but drastically better in end result.
If you want to focus on the very best result for body + face train 2 separate models on 2 separate datasets - one focused on body (full, medium shots, poses) the other on face (mid, close shots), then use 2 step generation with face model over image generated on body model.
If you want easier process - balance your dataset well for close and mid shots (30% mid, 70% close)

mlado•5/18/25, 10:08 AM

Okay thank you, I have a 4070 ti super, is that sufficient for fine tuning?

mlado•5/18/25, 10:09 AM

And yeah tbh I watched doctor futkans video about fine tuning vs lora and he also said that lora is inferior

Timson•5/18/25, 10:09 AM

Idaely you would have to rent A6000, it's 0.3$ per hour and training would take 6-10 hours

mlado•5/18/25, 10:10 AM

Okay, thats through runpod right

Timson•5/18/25, 10:10 AM

no, massedcompute

mlado•5/18/25, 10:10 AM

Oh okay sorry

mlado•5/18/25, 10:11 AM

I essentially just have to follow doctor furkan’s guide right

Timson•5/18/25, 10:11 AM

that's right

mlado•5/18/25, 10:11 AM

Hah okay, it will be the more complex way then hah, but I want best results possible soo yeah

mlado•5/18/25, 10:11 AM

Thanks timson

Mmlado I essentially just have to follow doctor furkan’s guide right

Timson•5/18/25, 10:16 AM

one last advice - the end result would depend on balance and composition of training data set even more than on the process itself. Training set would represent the features you want the model to learn proportionally. The more features you want to train (body type, poses, facial expressions) the more diverce dataset you woudl need and more training steps it would take to reach optimum training point

Timson•5/18/25, 10:17 AM

Think more about balance than on amount of good quality images

mlado•5/18/25, 10:18 AM

Okay, if you have time now, would you like to hop on a call and you can have a glance at the images I have and give your opinion, I can share screen

Timson•5/18/25, 10:22 AM

sorry, that would be too much

You can order paid consultation with Dr. Furkan but I advice you to have some experience on your own first with tutorials

mlado•5/18/25, 10:23 AM

Okay, thank you regardless

Mmlado Okay thank you, I have a 4070 ti super, is that sufficient for fine tuning?

Furkan Gözükara SECourses•5/18/25, 11:14 AM

100% you can train on that gpu

Furkan Gözükara SECourses•5/18/25, 11:14 AM

if you have 64 gb ram

mlado•5/18/25, 12:37 PM

yeah thats the thing unfortunately I only have 2x16 gb 6000mhz cl30

mlado•5/18/25, 12:38 PM

if I were to upgrade my ram, can I just order another 2x16 6000mhz kit and have a total of 4x16 or will I be better off with dual channel 2x32

Mmlado if I were to upgrade my ram, can I just order another 2x16 6000mhz kit and have ...

Furkan Gözükara SECourses•5/18/25, 12:48 PM

i recommend get 2x48 if possible

Furkan Gözükara SECourses•5/18/25, 12:48 PM

4x ram usually causes too much problem

Furkan Gözükara SECourses•5/18/25, 12:48 PM

but it depends on motherboard a lot

mlado•5/18/25, 12:50 PM

oh okay, thanks for the advice, my motherboard is a new model b650 called Eagle AX by Gigabyte, I bought it for my 7800x3d so should be good enough

mlado•5/19/25, 9:26 PM

I have 70 images in my data set to create my realistic instagram ai model, how many epochs would you recomend to use when fine tuning?

mlado•5/19/25, 9:28 PM

perhaps 100?

mlado•5/19/25, 9:29 PM

I know that Dr Furkan said that best epoch is 40 when he did 256 images, and 140 when he trained 15

mlado•5/19/25, 9:29 PM

But I am still unsure hah

Mmlado I have 70 images in my data set to create my realistic instagram ai model, how m...

Furkan Gözükara SECourses•5/19/25, 11:44 PM

for 70 images go up to 150 at least

Furkan Gözükara SECourses•5/19/25, 11:44 PM

and compare

mlado•5/20/25, 9:34 AM

I have 58.6 GB of free space, will that be enough to download the SUPIR upscaler
