Blocks of picture moving/jumping around

andy

Help! I don't know what I am doing wrong!! I am capturing from an analogue camcorder and also from old home/family movies (videos) on VHS tapes. I have a rather new computer amp; it's got lots of HD space, Ram etc. I bought a MSI TV@nywhere master PCI which includes silicon tuner amp; CX881/CX883 Decorder amp; realtime MPEG-4 Encoding support PCI TV-Tuner card: Conexant 2388x video capture. My computer is a HP and I have WinXP on it. I am using Ulead VideoStudio 8- capturing with MPeg-2, 24 bits/720 x 480, constant bit rate of 7000kbps, speed/quality 74%, frame rate 29.97 fps, aspect ratio 4:3, realtek AC97 audio, DVD-NTSC.
After I capture and I review the video for editing...there are huge quot;blocksquot; of the picture that seem to jump around/move/jerk. This is the best way that I can describe it! I am not sure if there is a technical name for this. What am I doing wrong? When I play my video through the TV to watch it, it does not do it only when capturing! How do I fix this problem??? Please someone respond!!! Thanking you in advance!!

I have some experience with both DV and VHS captures, but I've not seen this one. The best thing I can do for you is forward this over to the Capture Forum where more experienced hands can get ahold of it. You might drop back in and mention if the problem is with your camcorder cap's, or the older VHS source.

Since your playback is good but your capped files aren't, you might want to capture with a different program, but if you supply feedback when they request it, the hands in Capture will get you lined out.

I've had some similar problems converting my VHS tapes to DVD.
The only thing you can do is test different programs, anyway I'll give you some tips that can help:
Don't capture directly in mpeg2, you should capture in AVI with huffyuv codec.
Find out which capture program gives you the best quality: Capture the same clip with different capture programs and encode them with Videostudio at 720x480. Record them in a rewritable dvdr and look at your tv which clip looks better.

Duplicate your captured avi (720x480) file through Videostudio with huffyuv (make sure that RGB output is checked or videostudio will crash). To me Videostudio seems to filter automatically the avi file and enhance the quality.

The last step is to encode the avi file to mpeg2. The encoder that works best for me is Canopus Procoder, Cinema craft encoder also does fine.

Well, this is my quot;recipequot; for converting my VHS tapes, the converted DVD has the same quality as the VHS tape.

I hope these tips help you, if they don't you should start tresting all kinds of programs, I've been testing for more than 3 months till I got the desired results.

Hi, I got that problem solved..and now I am trying to convert a beta tape to DVD (my dad videotaped all of our old 8mm films and put them on a betamax tape). I am having a lot of difficulty getting the same quality as is on the tape, so I am trying to follow your suggestions quot;recipequot;. Daahhh! I was experimenting and burning tries on to DVD until I read your response again and noted that you used rewritable DVDrs!! I ran out today and got some! Can't believe that I didn't even consider that! Right now I am sampling with a few different programs capturing in AVI with huffyuv codec. Once this is done, do I now insert the avi file into the time line in  VideoStudio? Do you do your adding transitions and titles etc. here or do you use another program first? If so, which one? When all this is done, do I create a video file and indicate that I want MPeg 720x480 or do I specify NTSC DVD or is this where you use the Canopus Procoder encoder? Do you use VideoStudio to create chapters amp; burn or something else? Sorry I am asking so many questions, bit I'm (as you can) still learning this stuff and if I can follow your quot;recipequot; it will give me a great jumpstart!! Thanks for any help amp; suggestions that you can give me. I sure do appreciate it!!!! Thx CAnn

VS is a great consumer-grade tool.  It includes capture capability, non-linear editing, and the ability to easily encode and author DVDs.  But as a consumer-grade commercial product, it makes many decisions for you.  Making the content quot;look betterquot; may include automatically deinterlacing -- something you may not want to have happen with this sort of content.  Since the interlace artifacts are produced by this special Telecining, deinterlacing would only degrade the image.

Learning what what specific tools and procedures you're now using to capture, and perhaps a sample image of how it looks ... would help us help you....Once this is done, do I now insert the avi file into the time line in  VideoStudio? Do you do your adding transitions and titles etc. here or do you use another program first?...

Its up to you.  VS can certainly be used for editing as well as encoding/authoring DVDs, but the content may not be an acceptable source -- In my case, when I dealt with this non-standard Telecined video a couple of years ago, I didn't use VS at all.  

Have you seen our Capture Guide?  Its quite technical, but you may find some of it helpful.
