7D raw buffers cracked by Magic Lantern

Alex of magic latern announced that he found the raw buffers on the 7D and he got silent pics to work.

To recall, the path of development on the 5Ds was like this, first it was silent raw pics that record in bursts which eventually became continuous recording of raw onto the CF.
Hopefully the 7D follows that path.
Looks like its looking up for this dual digic beast.

Posted this also at industry news. Magic lantern cracks 7D Raw buffers.
Feel free to remove one Chris if this is redundant. Just felt to spice up the forums a bit.

This news could not have come at a better time. I was just about to put my 7D on ebay.

Re: 7D raw buffers cracked by Magic Lantern

There are now postings of burst mode raw video out. I definitely see raw video coming to this camera sooner than later. :)

Also, A1ex on Magic Lantern did a benchmark and found something peculiar, its the only canon dslr they tested where the write speed is significantly higher than the read speed.

A taste of what 7D raw video will look like. :)
This is from the raw burst mode.

Re: 7D raw buffers cracked by Magic Lantern

This may be a dumb question, but what does raw video do for me?

Re: 7D raw buffers cracked by Magic Lantern

14 Bit uncompressed (almost) 90mbs 12 steps of latitude and stunning VERY gradable footage.

Re: 7D raw buffers cracked by Magic Lantern

Thanks Jerry. Would you typically convert it to another format before editing?

Re: 7D raw buffers cracked by Magic Lantern

You have to convert it after you grade it to edit. Workflow is a little more cumbersome, but the results look amazing from what I have seen online. I'm saving for a 5Diii right now, but this hack has me thinking.

Re: 7D raw buffers cracked by Magic Lantern

With 5D2 RAW, we are getting amazing results for green screen work. Our workflow is...

1) Copy to two locations.

2) With one location convert the files to individual, uncompressed DNGs.

3) Convert to compressed DNGs, which still have amazing quality and have roughly 5:1 compression. (Most of our pixels are green. "Normal" video might get 2:1 or 3:1.)

4) Make a Cineform proxy for editing.

5) After the rough edit with Cineform, do the effects and coloring work, using the selected files. Render to Cineform for the final assembly.

6) And so on...

BTW, we tried CineformRAW, which compresses REALLY REALLY FAST. But the quality was a step down from compressed DNGs. (It's a bit noisy.) Compressing with normal Cineform is slow, but gives better results than CineformRAW.

For normal video work, CineformRAW looks like the best way to go for fast turnaround with good quality. For effects work, however, Compressed DNGs have the best balance of quality and size.

In the end, we archive the Compressed DNGs rather than the originals or Uncompressed DNGs. Keep in mind that if you shoot a lot of RAW content, there are storage costs.

BTW, the results are amazingly good. Not only do we get tons on dynamic range without block artifacts, we avoid filtering and aliasing (we shoot crop mode) and the keys are fantastic. We can shoot long hair that is flung wildly and fast moving hands and pull excellent keys. :)

Re: 7D raw buffers cracked by Magic Lantern

What a relief; perhaps my 7D kit will finally sell! I needed this news -- thanks for posting, Ted!

Re: 7D raw buffers cracked by Magic Lantern

Update.

ML devs scrambling to compile raw_rec module. Hold your breath....

What makes 7D more exciting is that along with 5DmkIII, they are the only canon dslrs with the sensor capability to shoot with the DUAL ISO feature made by ML dev A1ex.
