How to create an infinitely looping video?

Trying to figure out how to create an infinite loop. My current attempt has been:

  1. I2V using LTX2.3, save last frame is image
  2. I2V using LTX2.3 first-frame-last-frame node where the first frame is the last frame from step 1 and the last frame is the original image used in step 1
  3. Merge the two videos

As you can see there is a visible shift when transitioning from the 1st video to the 2nd video. Reddit won't automatically loop the video but there is also a visible shift when the video loops.

Is there a better way to do this?

Edit: Had a problem with my first-frame-last-frame subgraph. Fixed it and now just feeding the same image as both the first and last frame creates a loop.

Micron 3500 SSD (Crucial T500 OEM version) slow random read/write

Received a 2nd hand Micron 3500 2TB SSD today (this is the OEM version of the Crucial T500). I am a little concerned about the random read and write speeds as they are considerably lower than the review sample from THESSDREVIEW's website (3rd image).

If anybody who owns a Micron 3500 SSD can provide their own results (CrystalDiskMark with setting "NVMe" and profile "default") that would be greatly appreciated.

RTX 3060 12GB vs 5060 Ti 16GB benchmark on popular TTI models for anyone interested

Upgrading my PC and wanted to see the uplift:

Model Size(GB) Resolution Steps CFG RTX 3060 RTX 5060Ti Speedup
Z Image Turbo Bf16 12.3 1024x1024 8 1.0 20.53s 11.33s +81.2%
Anima Preview 3 Base 4.2 1024x1024 30 4.0 49.13s 28.07s +75.0%

Ideogram 4 Fp8 Scaled 18.6 768x1376 20 7.0 3 mins 19.63 s 50.79s +293.0%
Qwen Image 2512 Fp8 20.4 1328x1328 50 4.0 10 mins 06.00 s 5 mins 38.28 s +79.1%

Average of 2 images excluding model load time.
Specs: R7 3700X, 32GB DDR4 3600MHz, PCIe x16 4.0, Fedora.
Using ComfyUI default templates.
Default launch args.

Edit: Added model sizes. Also, I have already disassembled my PC and won't be taking any requests sorry.

Edit2: Updated Ideogram model size to include the unconditional model.

Understanding PCIe 4.0 vs PCIe 5.0 GPU Slots

The general consensus here is that 4.0 vs 5.0 is negligible on 5.0 capable GPUs. However, I’m wondering if that is actually the case when working with models larger than the GPU’s VRAM.

As I understand it, large models can be partially offloaded onto RAM and only passed to the GPU when needed. Let’s say the actual UNet is larger than the available VRAM. If layers are being offloaded and loaded to/from RAM at every step, wouldn’t halving the bandwidth between the GPU and RAM by using PCIe 4.0 have a noticeable effect?

It doesn't seem like anybody is actually testing this, so I’m wondering if anybody has any numbers outside of gaming benchmarks?

Reason for asking: I am intending on buying a NVIDIA GeForce RTX 5060 Ti 16GB. Due to RAM prices, I’m looking at a DDR4 board with a PCIe 4.0 x16 slot instead of PCIe 5.0.
