USB recording via ExtraWebcam or similar...

[rawfa]

Hi guys,

        I´m new here so I´m not sure if this is the right place to post this, so MODS, please feel free to move it if necessary.
       While I was waiting for my CF Card to arrive I´ve started looking into ways of testing the MarkII by recording via USB. I´ve downloaded a program called "Extra Webcam" (http://extrawebcam.com/) that allows you to record directly from the camera via USB. I was able to select 24p and a couple of other options but the resolution I´ve got was 1024 X 680 (every 30 seconds I was getting more or less a 150mb file) . I was thinking that if such a simple little program allows to do this, then there must be others that allow you much more control. And if there isn´t it doesn´t look like a very hard thing for a programmer to do (bare in mind I´m not a programmer and this is just an assumption).

That is the tiny sized you get over USB... haven't tried to alter it.

I did not know this application.
I'll test it as soon as I can.
Maybe it's a good tool for me...
I have a few things in mind.

Thank you.

The guy said he was getting a 92.56 Mbit/s datarate!

I´ve been playing with it all day and other than the weird resolution, the app stops receiving image each time you go into the camera profiles or use the magnify functions (which a shame because it would be cool using the laptop monitor to focus and do small adjustments). If you guys look at the application you´ll see it´s something pretty simple. I´m guessing a skilled developer wouldn´t have much trouble using this code to come up with somethings a bit more robust with more options. It could be a great tool.

Ok, going to try it. Seems to get same results as saving JPEGS(or 422) to card when tethered on T3i. FPS lagging is the problem... I'll see what it does on 6D.

Awesome. It would be pretty cool to have 4.2.2 and higher bitrate compression.
I did notice a little jerkiness in one or 2 shots.
Also, when I tried the application I cannot recall if weird resolution adapted the original resolution and if it cropped it...

On 600D, small size, 5fps.
6D.. can't connect. The demo wont even let you see the image.

With that: http://eos-movrec.sourceforge.net/
I get out 25-30fps! Not in Movie-Mode tough... Just Manual Photo-Mode, So LiveView only on PC, but works great!

Afaik it saves the Live-View Buffer compressed with MJPEG
It's Open-Source!
