Protip: Most people clip to get rid of the file size problems brought on by converting entire series to lossless.

Thanks. ;) Now I'm going to go post my install error messages in the other forum. Heheh... oops.

Yeah, I was kinda getting that idea after 15Gigs... Call it an epiphany from Kamui. (He's God, right? :twisted: )

Kamui, you are my one, true love... Er, I mean Fuuma... Uh... oh, hell with it. I just want to watch them make out.

also if you disable the audio that should save you file space as well :3

Yep, yep. Chopping the ends, using a new codec and VDM, I was able to reduce size significantly. (1/3rd the previous size or less.) Not quite sure how to disable the audio yet, but... I reckon I can split that off of there somehow and chuck it.

I was able to detect a degradation in quality with Lagarith when I got it working nicely, but then I'm obsessive-compulsive and I notice everything. ;P It's slight, but it's there. We'll see how it cleans up after a bath, a haircut, and a new suit. (If only this wasn't a new eyeglass prescription. I'd never have been able to tell! ;>)

Err...Lagarith doesn't lose quality. It's a lossless compression (which is why the file size is large). >_>

And to disable the audio in VDM, go to Streams > Steams List, and it should list the audio stream there. Just disable it in that window.

The loss in quality you think you noticed was most likely due to VDM's output preferences being set to 16 bit color, their default.

Newp. I distinctly set them to 24-bit beforehand. ;)

Hey, for all I know, the preview windows opened backwards (output, input). I'm just tellin' ya what I saw. I looked very closely.

Could it have something to do with the container change? Remember I was using a WMV container with a highly tweaked WMV9 codec (and the only reason I wasn't using 10 is because YouTube has a hairy conniption-fit over it. Still needs more testing).

Hm. Or it could have been the DiVX I was encoding from. I had both versions on there and... hell if I can remember that far back. All's I know: Lagarith, right pane, experienced detectable image degradation. Not much, but it was there.

I don't know what to say then - Lagarith is lossless. It has no loss. It might be some sort of display/decoding wonkyness, but it's not quality loss on the digital level.

The output pane doesn't show your video having already been compressed to Lagarith. If you see loss in your output pane then it's the fault of your filtering and it will appear in anything you render. Compression only happens after you save the file back out of VDM.

The guide says that DV is an okay way to go if you don't plan on pre-processing and you are short on disk space.

I was going to add, I would not want to compare WMV to DV in any way. Saying DV and WMV are both "lossy" doesn't really tell the whole story. One is an editable codec, one is most certainly not.

but either way BOTH lose quality when you use them, therefore they are lossy... if you don't want to lose quality, you should use a lossless codec or uncompressed.

That's something I would believe easily.
