ATI clone Tevion USB brightness too high?
In virtualdub, the default brightness is like 128, should it be dropped to 100? It does seem rather high.
But you can always tweak brightness later when encoding or during playback with most media players. What's the most nondestructive thing to-do here? I noticed the brightness was pretty high even on my DV Hi8 captures I just did straight out of FireWire. Maybe this is just actually an accurate representation of the source. |

If not, the levels could still be "wrong" since the analog-to-digital converter tries to automatically set the levels, and this process isn't perfect. |

Setting this card is not too dissimilar from setting the ATI/Startech audio hack, on those cards. It just needs a bit of tweaking before starting a project. Make yourself a preflight checklist, including VirtualDub settings, VCR settings, cabling/wiring, TBC, card settings, etc. Verify everything, reset anything as needed. Pretty simple stuff. I probably need to share my checklist, don't think I've ever done it. :hmm: Quote:

Good points, I think I'll try 116. And the rest at defaults, I've set everything else up well and no other issues.
Just this brightness seemed a bit odd, I'm going to tweak things post-capture if I need. I just wanted good settings for all-round stuff. |
At the stock levels for post I've found Tweak(bright=-10) in AviSynth, reduces it to a more realistic level. Stock is way too high on everything I've tested it on, switched to 116 now though.

Unless the tapes had crushed whites, the off-ness is not drastic, correctable in post if needed. Do correct it now, but previous captures are probably fine. If you're already planning to correct in Avisynth/VirtualDub filtering, then it becomes ever more moot.
And if you're tapes were dark/underexposed, the off levels may actually help. I've found 116 to be accurate to ATI AIW, which normally needs no adjustment. |

But yeah corrected to 116 thanks for that value, I was playing around with it myself and I came out at around there as well. But I don't have a calibrated monitor or anything so it's all a shot in the dark. |

You should also set Sharpness to 0. |
