Hello everybody. I don't think this is a VDub problem, but my codec config problem. I'm just hoping someone here knows how to help me.
Someone gave me a video file, and a screenshot from that video file. But when I open the video in VDub, seek to the time the screenshot was taken, and make my own screenshot, the image I see is (visually) worse then the original screenshot. By worse I mean - objects are more blurry / pixelated / have visible compression artifacts, while the original screenshot looks more clean.
So the main question is - is it possible that my machine renders this video with worse quality then the machine original screenshot was taken with. And how can I improve this quality (Decompressor is fddshow (H264), I saw fddshow has a TON of settings I do not understand, so I was wondering if changing those settings can result in better image output).
If it takes more processing time, or it'll make output files larger - that's fine. I'm trying to maximize the quality. |

Using codec H.264 to AVI files in VirtualDub is not wise. VDub for x264 encoding process will always be worse can cause delay time between video and audio (unsynchronized).
I suggest you may use Hybrid to encode H264 for AVI, thereafter open it in VDub. In Hybrid you can use x264 codec to encode without any delays. Have try... |

Maybe you should check the "Output color depth"-setting, via the Options-menu > Preferences... > Main ; Quick Preview defaults.
Sometimes it is on "Fastest (16-bit)" ; better would be to set it to "Match display depth". |

You got compressed copy of original video. Nothing wrong with your decode. |
