So, is the issue when your strobe light flashes you only see the light flash in a horizontal chunk of the frame? or you are using a constant light source and you see thick horizontal lines scrolling across your screen?
The latter issue is caused by the way your cmos chip captures an image. It is the same reason CMOS chips succumb to rolling shutter jello-vision effects. It is unavoidable while recording video around flashes. You can “fix it it post” if you like by adding the effect to the rest of your footage over that frame.
Otherwise use a camera with CCD chips.The later issue is caused by certain light sources (most commonly fluorescent tubes). If your shutter is not set to a multiple of the power frequency of the light source (60 in NTSC countries, 50 in PAL areas) you will see these lines. Good old fashion tungsten light sources do not cause this issue.

Very strange! I’ve been using mpeg streamclip for many years and it has never deleted any source footage on me.
Did you look in your trash bin? Try a search for the file in Finder – perhaps it was accidentally moved into another folder…

Came across this gem – 90 degree mini. Only ~$1.75 each if you order 1000. ;-/

My bet is on cable. They are not manufactured for production purposes and do not last. I burn through them like crazy.
I once thought my camera’s port was fried. As it turned out both cables I had on hand were duds.

A let down for some… but leaves hope for the future. I too was hoping for a $5-10K EF mount competitor to the AF-100 and NEX-FS100.
Even though Canon shot high with a competitor to the higher end F3, it is a sign that they have pledged focus into the large sensor S35 video market. Sony released the F3 well before they went FS-100. I have a good feeling that now that they have announced the flagship model – other more affordable units will follow.
My prediction for the lower end companion camera to the C300: Single chip, HDMI out – no SDI (or limited to 8-bit) Possibly lower bit-rate compression.

Other than that the Kessler is solid. It’s build quality is excellent and slides like a dream when the belt isn’t bouncing around. I did like the resistance the crank and belt provide, but the cost of vibration through to the lens to me is unacceptable.
Before I removed the band I would have to hold the edge of my matte-box or somewhere else on my camera rig to absorb the vibration.Colin McQuillan

Although they are both slightly more than the $500 you want to spend, FWIW I own a Kessler pocket dolly and have used a Cinevate slider, and between the two I kind of wish I had the Cinevate. I find the teeth of the band in the Kessler translates vibration through to the lens. It can be very annoying as you pay more for the crank/band and I ended up removing it to make the slider usable for the type of production I do.

3″ (inches) is not much track! Perhaps 3′ (feet) is more what you are after? 😉

[Chris Barnes] “my only loss, will be a little bit during the slomo shots due to scaling, correct?”
Yes, just a little hit on the 720 footage scaled to 1080. For web and DVD I don’t think you will notice much at all. I’ve used 720p60 GoPro shots in 1080i broadcast commercial projects as well and it stood up great.

[Chris Barnes] “I have been filming everything 720x60fps”…
[Chris Barnes] ” and dropping into a 30fps timeline inside of vegas movie studio”I’m not a Vegas guy, but make sure it is handling your 60fps material correctly. In FCP (pre X) if you don’t retime the footage to playback 30fps(50%slomo) before dropping into a timeline (either in Compressor or Cinema Tools) it basically throws half the frames away in timeline, and then blends the resulting 30 when you slo-mo to 50%, not re-introducing the addition frames of the original footage. Plenty of folks fall victim to this without realizing they are shooting 60fps for no benefit unless they treat the footage properly before bringing into the editing software.
I hope Vegas does this better!Colin McQuillan
