-nvidia 0|1|2|3|10

0,1,2,3: explicitly uses nvidia GPU device #0,1,2,3 (same index as nvidia-smi)

10: use CPU/iGPU.

Auto detection

-vram 10-90 (in percentage)

Set available VRAM manually. Will use only a fraction of the VRAM (10% - 90%)

Examples:

1). videosrcmd.exe "C:\test.mp4"

Will process the video under path "C:\test.mp4" and save the output as a .mp4 file into "C:\test_2x.mp4". The upscale factor will be 200%. Whole video will be processed. Device will be automatically chosen.

2). videosrcmd.exe "C:\test2.mp4" -o "C:\test_output_pngs\test2_outputs.png" -s 4 -b 3 -e 6 -nvidia 1 -vram 70

Will process the video under path "C:\test2.mp4" and save the output frames as pngs under the folder

"C:\test_output_pngs\test2_outputs". If there is no such folder, the software will create one. The upscale factor will be 400%. Video will be processed from the 3rd second to the 6th second. The software will run by Nvidia GPU. If your device has two GPUs, please make sure to set the gpu number to the correct one (same index as nvidia-smi). In this example, Nvidia GPU device number is 1. The VRAM will be used is 70% of the total available VRAM.

3). videosrcmd.exe "C:\test3.mp4" -o "C:\test_output_pngs\test3_outputs.png" -16bit -w 1920 -h 1060 - c -nvidia 10 -nd

Will process the video under path "C:\test3.mp4" and save the output frames as pngs under the folder

"C:\test_output_pngs\test3_outputs". If there is no such folder, the software will create one. Output pngs will be 16bit with 1920 pixels in width and 1060 pixels in height. If the output aspect ratio is different from the input, it will be cropped. The upscale factor will be 200%. Whole video will be processed. The software will run by iGPU/CPU. No preview display windows will be shown.

4). videosrcmd.exe "C:\test_image_sequence\image_%06d.png" -fps 60

Will process the images under path "C:\test_image_sequence\" and save the output as a .mp4 file under the same path. Images should be in png format, and their names should be like "image_000000.png", "image_000001.png", "image_000002.png", and so on. Output video will be in 60 FPS.

3. You are all set! Please wait for your upsampled video and enjoy it!

Gigapixel AI for Video FAQs

1. What is the minimum hardware requirement for Gigapixel AI for Video?

We suggest you to run Gigapixel AI for Video on high end Nvidia graphic cards. The minimum requirement is GTX 1050 with 4 GB VRAM. Any graphic card later than GTX 1080 (included) will do a fairly fast job.

If you do not have a Nvidia graphic card in your device, the software can run on your Intel iGPU. Typically, it will be 5 times slower. If you do not have an Intel iGPU, the software will finally fall back to you CPU, which can be 10 times slower than the Nvidia GPU version.

2. Can Gigapixel AI for Video work on Macs?

For now, Gigapixel AI for Video cannot work on Macs. It can only work on Windows devices.

3. Can I do batch processing on several videos?

Sure you can! Please check the "Gigapixel AI for Video Command Line Mode Guide" to make sure how to write command line instructions. You can write all the instructions in separated lines into a .bat file and then run it.

There is an example .bat file in your video folder after installation. You can check and run the "test.bat" there. It will help you to generate 2 sample upscaled videos.

4. My machine cannot meet the minimum requirement. Is there a way that I can use this product?

We have a cloud service that can help you to upscale your videos online. Please check https://videoai.topazlabs.com/ for more details!

5. How long it will take to process a video?

We tested mainly on Nvidia GTX 1080. For a video from HD to 8K, it typically takes 4-5 seconds for each frame. If you upscale a video from SD to HD, it will take about 0.5 second for each frame.

6. What is the maximum size of an output video I can get?

Now we support up to 8K video output. Any size larger than 8K will cause a failure.

7. Can I process interlaced video?

Not directly. If your video is interlaced, please deinterlace it first before using Gigapixel AI for Video to upscaling it. We are working on a deinterlacer AI at this moment, stay tuned.

8. My machine has more than one Nvidia GPU, can I use all of them?

Yes and No. The program itself only use one GPU. However, you can open multiple command consoles and use videosrcmd.exe with -gpu 0 or -gpu 1 to run each GPU on a separate video at the same time.

9. Can I read in a sequence of image as input?

Yes but you have to set it up via command line. Please refer to example 4) in “Gigapixel AI for Video Command Line Mode Guide”.

10. My GPU utilization seems low in task manager. Is there something wrong?

In fact it is normal. The GPU utilization in task manager is not precise. If you want to track the actual GPU usage, please try nvidia-smi.
