Hi folks,


I recently shot some raw material with my 7D mk1 and noticed audio dropouts in every file after importing the .DNGs to Resolve (15 Beta).


I use a nightly build from 2015 on a 64GB CF card, but I've never seen this before.
There is audio at the start of every clip, but then it suddenly drops out.


Any ideas?







Kind regards,


Johan

Hi all.

Recently shot some raw material at my local airport with some aircraft landing and taking off. After conforming to .DNG and importing into Resolve, I realize that the audio drops out in every clip. here's a screencap:




Nov 2015 nightly build.

Virus detected on the Windows .zip..  So that sucks.

Hi. I'm using an older nightly build (don't have the exact version at hand, ill get back on that).

There are a few hiccups when shooting raw. For example, no overlays work. If I activate any I get corrupted frames in the material etc.

Is this issue fixed in later  builds?

Looked at merging large Raw-files here: http://www.magiclantern.fm/forum/index.php?topic=6143.0


Seems to be working with the File Joiner.

Yes, the card is wiped clean, no original files on the CF card.


Looking at some of my files here I realize that I've been able to convert files that's been over 3 GB, so I guess there's something else going on.


The ones that does not work are all the same size, 4,194,304 KB... There are a few files with different names with this size. It seems like there's been some sort of file-splitting going on... I guess in the CF card? But once again, they did play in ML-playback... 

[The Card is a SanDisk 32 GB 160 MB/s, out of the box.]

Just did a quick test with last RAW2DNG and a 4.3 GByte file. Exact file size: 4 848 451 776 Bytes. Worked well.

1. Download latest RAW2DNG.EXE and try again. Found here: http://www.magiclantern.fm/forum/index.php?topic=5404.msg34757#msg34757

If it doesn't work:
2. Further information needed:
- Exact file size
- Which file systems used
  - Card: Exfat or FAT32?
  - Drive: NTFS, I suppose?
- Method used to transfer files?
- Is this the first time you have troubles with RAW files > 2 GByte on this machine? If so: Anything changed since last success?

Ciao

Downloaded the latest version, still not working:


- Exact file size
- Which file systems used 
  - Card: Exfat or FAT32?  The Card is a SanDisk 32 GB 160 MB/s, out of the box.
  - Drive: NTFS, I suppose? Yes, both the transfer used and the internal media storage disks are NFTS.
- Method used to transfer files? I copied the raw+"RXX.rar" files directly from my SanDisk card onto my transfer disk out on the field. Then from the transfer disk to the media drive when back home.

- Is this the first time you have troubles with RAW files > 2 GByte on this machine? If so: Anything changed since last success? I think this is the first time that I've ever made any longer raw takes. (only been at it a couple of months  )



I read that the Mac version has had issues with larger files: "raw2dgn.app
More info on the GUI version discussion topic

raw2dng
Osx command line

Know issues
- Can't convert file bigger than 2Gb."

Do you have RAW2DNG.EXE in the same directory where the video files are?
If not: Do so.
Open Explorer, locate directory, press shift key, open context menu. You will find an entry "Open Command Window Here"
If you select this a black window with some white letters will pop up. Now type
RAW2DNG.EXE NameOfYourFile.RAW
and press enter key.

Report messages. You can copy contents by using context menu inside this window, mark with mouse and then pressing ENTER (not CTRL-C!). Content is now buffered and can be copied here by CTRL-V.

Hi Walter. I did this and got the message: "This ain't a lv_rec RAW file".

I'd like to point out that the shorter clips worked fine. And the long ones looked OK in ML-playback.

Sorry.

ML: Nightly May 6th 2014.

Raw2dng: no idea, I think its from April of this year.

No error messages, it just quickly opens the console window and just shuts it down again.

Using Windows 8.0

Hi,

I recently shot some raw stuff on my 7D using ML. Some takes were pretty long, and it seems like the raw2dng.exe wont take these big files... (they´re about 3 GB+ in size.)


Any ideas on this?


Kind regards,

Any bugs may be reported here:
https://bitbucket.org/hudson/magic-lantern/issues?status=new&status=open

However, before you proceed make sure you can easily replicated the error. Provide a step by step instruction on how to replicate the error so that the developers can see what you see.

Also provide camera model, build (date/serial number) and module etc.

will do!


Thanks!

I have done hard testing on my card on several builds from february to today and had no problems, however I have 5D2, and a different build firmware than you. So its hard to say.

Just a thought - have you tried turning all global draws off and also chose preview: canon (not any preview that uses filters, like the pixely-grayish one).

Also try the different settings in the canon menu regarding video-mode. On my 5D I can choose NTSC or PAL. If I choose PAL and 24fps i get better performance than NTSC 30fps and fps-override: 23.973.
Its like i get some vertical sync problems when using the latter, and once (have not been able to reproduce) I got a magenta bar at the top of the frame.

Also make sure you are not zooming or anything while recording. (there is a setting that turns on 5x zoom if touching the focus ring - turn that off - its of by default though).

If you can find what makes the error you can at least report it.
good luck

It seems that turning off all Global Draws fixed it! Many thanks!

However, this means that it's not fully funcional with raw, at least on my 7D.

Where do I report these findings?


Once again, many thanks!

Many thanks for your suggestions.. I'll try them out..

A few things:

How do I chose "preview: canon"? I cannot find that in any ML-menu.

On the 7D, even though if I chose "PAL" 24 fps, ML indicates that this still is 23.976 fps override... Not sure why. I always thought that the PAL "version" of 24p really was 24 fps, and that NTSC-24p was 23.976.

Testing goes on!

OK, so I got my 160 card today.

Went out to shoot some tests and the performance seems better. I did not get any aborted shots.

However, I still do get some occasional "pink frames"..


Does anyone have a clue here?  I downloaded the latest Nightly Build for the 7D for my new card.

[up to]

I shoot with the 7D, ML raw etc. I use (3) transcend 64GB (1000x) CF cards and they work almost perfectly. There are a few hick-ups here and there but when I hit record, I capture every frame without those magenta errors. On my older transcend cards, 32GB (400x), I had those problems all the time. I've even ran into a problem where it would drop a frame and keep recording without stopping. When I saw how unreliable those cards were for raw video I looked around the forums and found that the Mark III shoots raw 1080p with no problems. So I invested in the 1000x cards.

I don't know much about converting (400x or 1000x) to (mb/s or MB/s) but on the amazon page I bought my cards from shows that the 1000x writes at 120MB/s and reads at 160MB/s.

Thanks Aace. Looks like those magenta frames are CF-speed related then.

Speeds one the SanDisk site are:

Transfer speeds of up to 160MB/s
Shot speeds up to 150MB/s


So I'll go with the SD 32GB one.

I use the sandisk extreme pro 160mb/s on a Mark II, and it works fine.

Ok, thanks!


I'd really love to hear from someone shooting raw on the 7D.

?
@windh
I have the Sandisk Extreme Pro 64GB 160MB/s (1067x). This card is very fast but the 160MB/s is the read-speed. Actual write speed is around 150MB/s. The card has the VPG65 logo (Video Performance Guaranteed), which means that the card will always deliver write speeds above 65MB/s! In reality the card writes at around 70MB/s in my 5D2. In my USB3 card-reader it delivers the promised 150MB/s write speed. I think this card is very stable and I would definitely recommend it if you have the money.

Thanks for your reply poromaa.

Do you believe that my limited recording time and the pink frames are due to a too slow card?

I will probably invest in a SD 160 32GB then!


As for the non-constructive trolls: cheers. 

Anyone? Any experience from this card?

Is it my current card that makes the shot stop after 10 secs and produces the pink artifacts?

So, other than limited recording time to roughly 10 secs, I get some frames like this:

Hi peeps.

Fairly new to the RAW family.

I have one SanDisk 32 Gb @ 60 and another 16 Gb @ 90.


When shooting with my 90 at 1792 res I can only get a few seconds of footage, then it beeps 5 times and I get a message saying "early stop ( 8 ). this is a bug. please report..."

Guessing this is because the card is too slow?

Strange, because on my 60 card I could shoot continously more or less, but getting pink frames every now and then when looking at the footage..


So, if I'm correct in that it is speed related, how will the SanDisk 160Mb/s work out on the 7D?


Kind Regards


Windh



EDIT: Just tried switching back to my 60 Mb/s card, and now it won't even record for one second before beeping out... Hmmm..



EDIT 2: Oooops...  Found out that in the Canon menu it was set to RAW+Jpg Large.. Changing it to just RAW made it record again for about 10 secs on my 60 card, then beeping out.
