I don't post much anywhere so please forgive.
My hardware is: AIW 800XL AGP, E4600 C2D @ 2.4, 2GB RAM, SB X-Fi, 2 HDD for OS & to save to, all on an
ASRock 4CoreDualVSTA with Via chipset
: JVC HR-S7500U (TBC really helps clean things up)
- I dont have anything OCed and is stable with APG @ 8X but I keep it on 4X
My situation is I am capturing VHS and have used the guides on this site with the settings suggested in them, resulting in good captures proportional to the original sources. I want DVD copies so I have used the MPEG guide, done multiple captures at different bitrates (as I learn) around the suggested rate of about 3000-3500kbps target, up to around 7000kbps. I know it says anything over about 4000 is just a waste of bytes with diminishing returns, but I figured if it is any better at all then its fine, as long as it fits on a disc, a burnt disc is a burnt disc and I dont care if it takes longer to burn. I captured using MPEG2-DVD
in MMC using the Cropping option sometimes when needed to get rid of distortion at the bottom.
I then decided to give AVI captures a try, again using the guides here (Thank You) with MMC and HuffYUV
multi-thread. It captured great and could definitely see the improved quality. Even with a very poor quality source tape I captured its 90 minutes with only 5 dropped frames and the CPU utilization was only at 10%, similar to earlier MPEG captures, so hardware is not an issue. I was just surprised that I could capture at 10% CPU utilization but it went up to about 40% during playback, since I thought both were software based being AVI.
Anyways, I then tried to capture AVI (always using the same source tape as above) in VirtualDub
instead of MMC due to its reputation and to be able to use its filters and features like cropping. The problem is, unlike with MMC, no matter what settings I change it drops frames terribly, 15-20%. The longer the capture the worse the frame dropping gets. In only 5 min of capture I can be down to about 23fps instead of 30. I am pretty sure that even though this happens, the CPU usage still stays at about 10-15%. Even when not capturing, the preview/overlay window drops frames and skips after a while and gets worse the longer it goes.
I am looking for feedback on possible reasons/settings in general or within VirtualDub
that may be causing this with the hopes of being able to use it.
Also, when I capture MPEG for DVD, 90-120 minutes is about 3-4 GB, which is fine for that purpose. But I would also like to give people a copy of the same captures for storage and playback on their computer, in a decent 4:3 resolution and format, with a codec/container that a Windows based computer with relatively basic common software would be able to play back, and have smaller file size of about 500MB-1GB.
What are the best options, and how do I get there, in steps.
Sorry for the length, but thanks for any help.
