Comparisons

Video quality

These results will differ from the standard edition and high-fidelity edition.
These results are applicable to Nintendo GameCube software.

Using DSSIM 2.9.7 and FFmpeg 4.2 for RGB SSIM & PSNR, with this reference image.

The analog-to-digital conversion parameters were calibrated for each source and device pair.
This isn't representative of relative signal strength. Sorting by DSSIM provide a fairly accurate ranking.

Blackmagic Intensity Shuttle

Using ADV7180 and ADV7604.

This 10-bit YCBCR 4:2:2 capture device is most representative of what you might see on a digital television.
As chroma is shifted right on YPBPR in/out, this was corrected in post-processing. Video and S-Video in/out suffer from internal interference.

FAQs

Progressive scan (720x480p)

How do I change Game Paks?

  1. Hold the Reset Button.
  2. Slide the Game Pak Ejector.
  3. Insert a Game Pak into the Game Pak Slot.
  4. Release the Reset Button.

Can I play Game Boy Advance Video?

Yes. You can do so by disabling Game Boy Player enhancements (--no-enhance), or holding a direction while the Game Boy Player logo is visible.

Why am I seeing a double split image?

Either progressive scan mode is enabled or, if using GCVideo-DVI, line doubling is by default.

If line doubling is at fault, the picture may also be scrolling with a slant.

Why is the input viewer barely visible on my capture?

If the input viewer has no discernible shape on black or white backgrounds, this is caused by a configuration issue.

If you're using analog video, set the video standard as "NTSC_M_J" rather than "NTSC_M" in the filter properties.

If you're using digital video, set the color range to full rather than partial. If this doesn't work, in the GCVideo menu under "Other settings", set "RGB Limited Range" to On.

How do I verify my Game Boy Advance ROM?

Original, counterfeit or reproduction cartridge

  1. Remove any accessory from the External Extension Connector.
