+ # LTX Video Generator (Personal Use)
13
+
14
+ A free text-to-video generator built on [LTX-Video](https://huggingface.co/Lightricks/LTX-Video),
15
+ running as a Hugging Face Space with a Gradio UI.
16
+
17
+ ## Deploy steps
18
+
19
+ 1. Go to https://huggingface.co/new-space
20
+ 2. Fill in:
21
+ - **Space name**: e.g. `my-ltx-video-generator`
22
+ - **SDK**: Gradio
23
+ - **Hardware**:
24
+ - Free CPU works but will be very slow (many minutes per clip).
25
+ - **ZeroGPU** is free if your account is eligible — best option for personal use.
26
+ - Or pick a paid GPU tier (e.g. T4/A10G) billed by the minute if you want faster, always-on generation.
27
+ - **Visibility**: Private (recommended, since this is personal use) or Public.
28
+ 3. Once the Space is created, upload these three files (or push via git — see below):
29
+ - `app.py`
30
+ - `requirements.txt`
31
+ - `README.md`
32
+ 4. The Space will build automatically. First build takes a while — it has to
33
+ download the LTX-Video model weights (several GB).
34
+ 5. Once it says "Running", open the app and generate your first clip.
35
+
36
+ ## Uploading via git (alternative to the web UI)
37
+
38
+ ```bash
39
+ git clone https://huggingface.co/spaces/YOUR_USERNAME/my-ltx-video-generator
40
+ cd my-ltx-video-generator
41
+ # copy in app.py, requirements.txt, README.md
42
+ git add .
43
+ git commit -m "Initial LTX video generator"
44
+ git push
45
+ ```
46
+
47
+ You'll need a Hugging Face **access token** (with "write" scope) to push:
48
+ Settings → Access Tokens → New token, then use it as your password when git
49
+ prompts for credentials (username = your HF username).
50
+
51
+ ## Notes
52
+
53
+ - LTX-Video is gated/openly licensed under its own model license — the first
54
+ time the Space downloads it, you may need to have accepted the license on
55
+ the [model page](https://huggingface.co/Lightricks/LTX-Video) with the same
56
+ account that owns the Space.
57
+ - Generation settings (resolution, frame count, steps) are exposed in the UI
58
+ so you can trade off speed vs. quality.
59
+ - This is set up for personal/private use — keep the Space private if you
60
+ don't want to share generations publicly.
