Early captures, disable VirtualDub frame drops/inserts?
3 Attachment(s)
Hi all,
I'm just getting my project going. Whilst I wait for a TBC I thought I'd test the rest of my kit and start configuring the software settings. In short, I'm pretty amazed with the quality I'm already seeing. Some crude screengrabs attached. This is from what I expected to be one of the worst of my tapes, as I know it was recorded way back in 1986 and on an old Ferguson 3V29. Yet I'm getting a stable picture (no tearing, colours in the right places), and even without a TBC almost no dropped or inserted frames. Question: If the VirtualDub options 'Drop frames' and 'Insert frames' are disabled, will VirtualDub still report any such instances even though it isn't 'correcting' them? I want to know if I can capture with these options disabled (as recommended in another thread) but still monitor for quality issues. Another question: So far I've routed the audio directly from the VCR to the line in of my on-board motherboard sound card. I've read that this isn't recommended, but it seems to be working well for me. I was planning to get a PCI Soundblaster board, but do I really need to? I realise my perceptions of quality are subjective. I'm not trying to cut corners, just interested in learning from others' experiences and reasoning. For comment/critique: I've got a JVC S7600 (PAL) which I picked up some years ago from Ebay, I'd guess has only seen light use. ATI AIW 9000 bought recently from Ebay, apparently brand new though card only so I had to find a dongle. I've rebuilt an original XP PC with an Athlon XP 1500+ and 512M of RAM, and am using VirtualDub. I did install ATI MMC 8.8 but experienced some crashes, I'm glad I switched as VirtualDub seems to have far more features. So far the whole thing has been quite painless and seems to be working admirably. Thanks to everyone who's contributed to all the guides and posts on this site. The ultimate purpose is to transfer a small collection of VHS/Video8 home movies from my childhood. I'm going for archival quality, and no particular requirements around target format. |

The video quality from ATI AIW cards mentioned on this forum are very good indeed. That would be consistent with your initial impressions of how good your tapes look to you. I know I'm forever grateful to this forum for pointing me to this line of capture cards. Best wishes. |

Motion matters, however. Tiny clips are always good to view (lossless not needed, conserve site space, MP4 is fine). Quote:

sanlyn recommended those in his guide, but I disagreed on the 2nd page. That was seemingly not being heeded, nor was I as stern as I should have been, so the first post of the thread has now been updated with some exhaustive info on those two settings. Quote:
In 20 years, I only had acceptable audio capturing once, from a Realtek on-board, on a system I used in the late 00s. I forget which motherboard, but it was high-end (a site donation, thanks indolikaa!), until it melted itself in 2014. That system ran hot. Quote:

RAM is a bit low, I'd try to max out at 2gb, a 1gb minimum. I ran 512 in 2001-2002, and it was tough a times, caused capture issues. That AMD 1500 is a bit slow. I know 1400 failed, and 1700 was touchy (and it also had 512mb RAM). These days, I'd outright build something with latter 00s or early 10s parts, dual-core Intels, SATA (not IDE, slow, yuck). Quote:

Thanks both for your comments, all really useful.
I will indeed do some tests to listen to audio quality on playback. If I can get hold of a Santa Cruz easily I might just do so anyway. Lordsmurf I do remember reading that you'd disagreed with sanlyn about the VirtualDub settings, I guess I hadn't picked up on why. What you're saying makes sense to me. I'll go and read your more detailed explanation! I know the PC spec is on the low side but so far it's holding up. I'm capturing in raw UYVY which helps reduce the load, mainly because I don't care how big the files are. Once I'm done I will indeed offer all my kit to the marketplace here, I'd be pleased to know that someone else can get some use from it :-) |
