I recorded a 12.7GB movie file. The raw to dng converter is not working correctly as 1% noted. I was able to play back all 3,592 frames in the camera by using the raw video menu option for playback. All the frames look good.

Just tried the new build. The cf_acc_mo module isn't helping, it's actually filling the buffer sooner.

You really do not need to have the cf_acc.mo module. That is just part of the cf card test.

5D3 update files. Replace existing files.

includes cf_acc: module as noted on http://www.magiclantern.fm/forum/index.php?topic=5471.msg36588#msg36588
Thank you, everything works.
   Now there is no problem switching standard movie recording in H264 after turning off the RAW.

Oh, it's this, my card was quickly shut down when filling bufera?
  before more than 100 frames to write without problems, now after 60  off the record (RAW)
...
I remove the file from the card and it was much better!
  Now I shut easily 370 shots!

My 1000x Komputerbay 128GB arrived today. Just as I had expected, it is quite slow. Topping out at 70MB/s... so I'm stuck with 1920 x 900 on a good take and most often 1920 x 840 to be safe. This is a slow 1000x card. I'm not sure how others like Cinema5D are writing 1920x1080 to the 128GBs.

For slow cards, this seems to help a bit:

I get similar speed results as you with my 128.  I have written about this issue here and on Cinema5D.  Bottom line, the KomputerBay 128s seem to be slower then the 64s.  Cinema5D has assured me that their 128s are fast so they just might have been lucky with theirs.  EOSHD was using 64s for his tests.  Most current reports of the 128s are benchmarking around 70MB/s.

Hey ML team,

Congrats and great work on ML over the past week! I have been following very closely and using the nightly builds since they were first made available. The results have been amazing and i can't believe how much progress has been made in such a short time. It's starting to look like a real usable feature!

There were some earlier mentions on this thread of being able to record raw video while simultaneously recording the standard h.264 stream to the sd or cf card. if this is the case then how would i go about enabling it. Without having to figure out how to turn on the necessarily code switches and compile it myself..

I am generally recording a solid 24 or 25p @ 1920x840 to a delkin x1000 16GB card on a 5d mk 3!

Cheers guys! Keep up the great work!

I tried a 5.4GB movie file. I was not able to convert it in windows, but I was able to convert it in linux.

(i) Would it perhaps be beneficial to compile a list of the different threads that deal with the different aspects of RAW recording? I know we're still in the very early days of the recent RAW developments, but this could easily keep growing to the point where it should have its own Forum category or sub-category?
Edit: (ii) Perhaps we need an additional moderator that is not one of the main developers so the latter can concentrate on their respective fields of expertise rather than forum-moderation?
Perhaps I am just confused and this post just added to the problem it sought to remedy.. If so, just ignore/delete it :)

Hi everybody, it's possible record raw more than 4GB? One minute its very few if you when you work with actors, external sound, clapboard and all the things outside cats, dogs, eternal mountines and trees. Thanks a lot!

That's amazing :D

You can record over 4GB yes but I think people are just struggling to open the files at the moment. Won't be long I'm sure :)
Lynne, some of these people have come from Stoke!

Linux version was tested and opens the files. Windows and mac... I think not so much... Well good news at least you can open any >4gb files you have.

There is also a raw_rec.o file in MODULES folder. Is this needed? New files you posted don't have this file...

Will these replacements files give more than 4gb recording-time for each clip?

What is the status of 5D2 aquisition?

If I can get a stable 1280x1080 I will be so happy

Heads up to the devs that shooting with the Anamorphic adjustment on the display seems to disrupt my write speed enough to drop frames. Using a Lexar 1000x, runs fine full screen but buffer fills up really fast when I switch to Anamorphic.

Anyone try the Delkin 1050X 64GB?  I'm wondering if the 120MB/sec write speed is real...

Check out amazon reviews... more than a few people say then can't get over 80 MB/s... the Transcend seems to be the better deal.

is it possible that write speed was faster months ago? i rarely remember i did a benchmark with 93 mb/s.
and i also bought it because amazon and other reviews were good...
i do not trust in transcend any more since they did not hold up ml on  my old 550d.
so the best way to go is a.. sandisk 1000x? i am looking for a new one now..

The raw_rec.o is not needed. only the raw_rec.mo is needed.
