Hi Pollykore,

The 7D encodes its files using H.264, which can be difficult to playback in real time - its very resource heavy.

After being converted to a lighter format, it should playback easily.

Thanks I just wanted to make sure once i convert it to prores or excam its works fine in final cut and the vimeo up load looks good. I just want to make sure everything is working well before i buy.

Can the HDMI output stream be recorded uncompressed HD to the nanoflash?

Sort of. You would need an HDMI to SDI converter box, which Black Magic and Convergent Design both make. Then you end up with 4:2:2 8bit, bit the output image isn't full 1920X1080.

The output from the HDMI looks like this:

I AGREE

It then has to be upresed to full 1920. This clip was captured with the Black Magic Intensity, and it also needed to have the 3:2 pulldown removed as the BM records the 24p in a 29.97 AVI wrapper. The Nanoflash says that it can record at 23.976 so that should eliminate this step.

The nanoflash appears to be available for rent at a few locations. If you rent one to try it out, please post some results! : )

7D overheating experiences

7D overheating experiences

Hi
I have a 7D and have used it extensively for video and stills shoots. It has overheated on two occasions. Both times when I was filming video in direct sunshine and the weather was VERY hot, above 35 degress C, in the dead of summer in Cape Town. On both occasions I was filming lengthy shots of approx 10 minute clips. On both occasions I switched off as soon as I saw the warning sign, blew on it to cool down and continued shooting - cos I had to.:shocked: I never got any pixelation or any strange video artifacts.

I also shot predominantly stills on an even hotter day and although the camera got really hot I never saw the warning sign once, so I think it is defenately a video thing..
