Greetings, everyone! I have a question regarding my Canon VIXIA HG20 camera and a buffer overflow error that has been causing problems for me.

Here's the situation I was doing a photo shoot of an F8F Bearcat from a B-25 Mitchell with all its windows removed in the back, creating a pretty bumpy environment. I wanted to supplement my pictures with video, but the HG20 would only record about 10 seconds of video at a time, before stopping due to a buffer overflow error. I've read a bit about it and found this may be due to the (Buffer Overflow error) vibrations in this environment.

Hello,

I am a student filmmaker and I am about to purchase a new camera. I am debating between a DLSR (something like the Canon 7d) or a prosumer camcorder (like the Canon XA10.) My budget is around $2,000 or so.

I already have a digital camera (the Nikon d80, which is decent) so I am leaning towards a camcorder. I feel that since if I am trying to be a filmmaker and not a photographer a DSLR is not the right direction to go. However, a lot of my friends have and recommend them because they are versatile (in terms of lenses and whatnot.)

I am directing a music video that involves a band playing underneath a
large oak tree that's wrapped very sporadically and randomly/hectically with multi-colored yarn. Is there a way to make the colors of the yarn
surrounding the band to change like a visualized without having to stop
the band and move the yarn constantly?

Whether you're using a Canon, Nikon, Pentax or other type of HDSLR camera, the big issue is keeping that bad-boy in focus. Yes, you can spend a couple of metric tons worth of cash on focusing gear but whether you do or don't keeping good focus without auto settings must be dealt with. Here's a vid from Stillmotion giving some good basic tips for keeping focus with the Canon line of cameras and a few items for monitoring your image during shooting. These lessons apply to whatever camera line you're using so take notes... there'll be a quiz!

Awesome a camera as the 5DmkII is, two main problems come from converting the the CMOS sensor image from stills to video are; Moire and Aliasing. Moire is the 'rainbow effect' when shooting video of fine detailed surfaces like certain rug and clothing patterns, brick walls, etc. Aliasing is those lovely jagged edges in the images when they should be smooth.

However, there's a solid fix for that now with the Mosaic Engineering Optical Anti-Aliasing Filter. Here's a vid by cinematographer Glenn Przyborski giving a rundown on what the filter can do in the MkII.
