  Serious Aliiasing on DVX100A

  Posted by Kevin Brusie on March 27, 2006 at 8:33 pm

  I have been shooting with the 100, then the 100A for about 2 years. The 100A has just over 100hours on the head. I have just recently noticed SERIOUS aliasing when shooting. It is possible that conditions never produced it, but recently while shooting strong horizontal lines (house siding in background) I have real issues – almost unusable footage – with the aliasing. It looks like it moves plus it appears to have Newton rings. For those not old enough or from a photo background, those are the diffusion rings that would happen when a negative was squished under glass.

  I am shooting 30P but it is there in 60i also… V detail is set to Thick…

  HELP!!! shooting again tomorrow and this is just crazy!

  Thanks for any help

  How often do you use a head cleaner? Sounds like the heads are a little dirty.

  Interestingly enough… I hadn’t cleaned the heads in a while (like ever!) I ran the head cleaning tape through as I was shown the evil red cirlce X of death. Then it still was the same (aliasing) and I ran it through again.

  Still there. I am afraid to run it through a 3rd time! Should I use a wet cleaning?

  Thanks Noah!

  I’d have the camera professionally cleaned. Most large dealers do this for $75.

  Thanks for the tips… I ended up getting chamois head cleaners and fluid from a local electronics wholesaler and cleaned the head myself. Took the protective plate off the cassette mechanism and cut the handles down on the swabs. I was able to get right in there, and be perfectly aligned with the drum… then spun it a round with a nother swab from above.

  It seems to have fixed the issue. I’ll have the camera serviced asap… once this shoot is done.

  Thanks again!
