Lossless compression yields smaller files on still content. So if you're capping newscasts, that explains that.
As per the other post, yes, 720x480 suggested.

You often get dropped frames during those first few seconds of video -- especially if a full-frame TBC is absent in the workflow. And from the sound of it, it is. You may have other dropped frames issues throughout the video, as the Panasonic TBC is only full-field (multi line).

I doubt it has anything to do with ATI, and uninstalling MMC is often an ordeal. That could set you back by weeks if it goes tits up, which is sadly quite common with ATI hardware. If it works now, leave it alone. And I think it's working.

Never run both MMC and VirtualDub at the same time. (Most all systems prevent it anyway, as Windows cannot share that resource.)

Thanks Lordsmurf!

That's strange cause this was done with an old family home video (camcorder now in VHS). And it's showing a little girl running around the house (with the background held relatively still). But I'd imagine most videos to have the background still as well? If the size for the lossless capture is normal then I'm a happy camper. =)

I guess at some point it'll be a dilemma between 640x480 vs 720x480. Eventually when all media goes to streaming off of hard drives (if it goes that route), and video playback software can play interlaced AVI without a hitch, I'd imagine 640x480 would be preferable. If there's another media that'll be popular after blu ray, do you think 720x480 would still be used for SD? Not sure why 720x480 is used as the standard for SD on DVD and Blu Ray.

I've went ahead and uninstalled/reinstalled the ATI software (because I wanted to downgrade from SP3 to SP2 and drivers got corrupted). I didn't install MMC for now and test run seemed to work with same results (I'm using just virtualdub for now). Do you believe that's asking for it later and I should go ahead and install MMC? (I don't run both at the same time but it seems like When I had it on the machine MMC loaded up automatically on start up and I had to turn it off through task manager)

They inherited the common Rec.601 standard, which was invented at a time when video and computer graphics were separate industries and originates in the sampling rate being based on one of the clocks used in the analog signal. In fact, the only reason HDTV & Blu-ray use square pixels is apparently at the insistence of one SMPTE member; there were loud voices who still wanted rectangular pixels. (One advantage being that rectangular pixels allow NTSC-type and PAL-type video to use the same bandwidth: 720x480x30 = 720x576x25.)

Broadcast pros have never used square pixel SD video, and there is no advantage to it since you won't find a 640x480 fixed pixel display anyway (well, maybe one of those old 853x480 plasmas could display a 640x480 video in the centre). If your display is upscaling anyway, there is no point in starting with 640x480.

Capture 720x480, use for archiving to disc, scale to 640x480 in software for streaming when needed.
If you have no plans to use ATI MMC, it's not needed.

VirtualDub resize filter is one way. (You have Mac, right? Use Parallels, and install Windows XP for Avisynth/VirtualDub work.)
