Ok, I'm a noob and I registered(in part) just to get my question answered. Is there a quality degradation just by running a video through VirtualDubMod? I have searched a couple different strings in the forum and couldn't find my specific issue. I have read and experienced personally that VDM doesn't load perfect quality vid but that is just a preview anyway. Unfortunately I have seen it carry over to my output.
I am trying to use some form of compressed AVI and so I use DirectShowSource in my AVS and Trim to make a clip. Ok, as expected not so pretty. I export to a Lagarith file. This is where I notice that my quality has indeed gone down. I open the original in MediaPlayerClassic and the quality is already super to the naked eye. I open my AVS in MPC and don't really see much difference if at all(its not like I can put them side by side because MPC will only allow one window). I then load my Lag file and it looks just as distorted as it does in VDM. Since my AVS doesn't look this bad I can only assume the problem lies with VDM. If it was just a matter of my original being bad I would just compensate as best I could and move on, but this makes me rethink my whole process. Has anyone else noticed this or is there something I need to do differently?
BTW, before you mention it I already have VDM set to "use output settings"

Sorry to take so long but I kinda fell asleep

1) Thank you for trying to help.

3) I'm an idiot. In the process of trying to get screen captures to show you I ran into some interesting things that effectively answer my question. Firstly, I tried turning off the Overlay function in WMP(suggestion I found on the web) in order to use a screen cap program. Just by doing that the original turned into the same quality as VDM. I never knew my vids were being cleaned up automatically. Next this led me to the "import video frame" function in Photoshop, didn't know about it before. Using it I found that all three(original, AVS, and Lag) were identical quality. So my whole point is wrong. This still does not explain why my original and AVS were cleaned up but the Lag was not, but I guess it only matters to increase knowledge.
If you know more or if I am seeing this wrong, please feel free to write in or correct me. Otherwise, I guess that is that. Sorry to waste everyone's time but I never would have found my answer had I not asked.

Change Output color depth from "Fastest (16-bit)" to "Match Display Depth"

which is moot because...BTW, before you mention it I already have VDM set to "use output settings"
