I was recently put in charge of capturing all my family's home videos (on VHS) and burning them on to DVD. The thing is, is that some of them are really old and are converted from FILM. I have an ATI AIW 7500 and I am using VirtualDub AVI capture. I am capturing at 29.97 FPS at 720x480 resolution. The picture looks interlaced when anything at all moves. I inverse telecined the file in VirtualDub (using both adaptive and manual modes, but getting similair looking results), so now it is at 23.976 FPS. The footage still looks highly interlaced. My first question is, Should I have done the IVTC? This is what it is used for, right? My second question is, How come the video still looks so interlaced after IVTC? Is that just the nature of VHS, or problem with my capture card or VirtualDub? My third question is, What do you recommend I do to fix this interlacing problem? I cant really resize it, because I would like to keep it at the DVD frame size. When I run DeInterlace or Area-Based DeInterlace it just kinda blurs the picture. This seems to be my only problem so far. After this I'm going to edit it in Premiere (24 FPS Progressive i hope...), and then encode in TMPGEnc Pro. Since this stuff is gonna be passed down for generations I would like the quality to be pretty good. It has already suffered enough deterioration. Thanks in advance for any good advice
Oh yeah, one more thing. The original film was shot on 8mm. Does anyone know how many FPS that would be? Also, it was telecine transferred to VHS in the mid 1980's.
I've run into a similar problem trying to copy vhs tapes to DVD. The tapes have been copied and run many times. When I import the video to my External Philips DVDR 985 or my a to d conversion card, the image is all jittery when ever there is a bright spot or motion (fork lift training video). It exhibits the same tendencies when I try to import it to my dv cam (canon GL1). Any thoughts?
If you are capturing from VHS you do not need to capture any higher than 352 By 288 pixels, because of the nature of the VHS resolution, theres no point of capturing more horizontal lines than there actually are, my advice for getting the best quality is to either capture at 352*288 or 640*480 Then resize to 352*288, and if you have enough Hard Disk space (and a Damn fast one too!!) then always capture in AVI first, then use a the best encoder possible at the highest setting such as a two pass encoding process. Capturing in AVI is not always possible because of two reasons (1) Eats your Hard Drive, (it takes up huge space) example 352*288 sized video clip of one minute will take up aprox 222MB!! (2)Theres a 2 GB limit on AVI file!! My personal view as to why your getting these interlaced pictures is because your capturing two higer resolution, capturing at higher does not mean better quality, its all about the source quality remember the Universal Rules: Garbage in Garbage Out!! And one more thing, use Half D1 mode for your VHS to Converted file before buring the DVD, and if your from the UK please dont bother capturing other than 25FPS (Its the PAL standard) Hope this has helped If you have lots to cature (ie in excess of 3 hours per VHS) then consider capturing to mpeg in realtime, trying using Ulead VideoStudio 6 (highly recommended for this job)If you play around with this software you will find that it will do the whole VHS to DVD process, with out the need for external software, it will even author DVD for you will menus etc.. Hope this has helped !!, please reply back!
