5D2 RAW video Builds 14-Bit

[Doyle4]

June sorry not July... thinking ahead!! haha 

[reddeercity]

i see your  point , i didn't realize that there so hi-priced
in Canada i paid 1/2 that $200.00 , I don't understand that, 2X the cost
How about HoodMan? or Toshiba 1066x ?

Ted, I bought a Sandisk Extreme Pro 90MB/s card, and it will do 1880x800 continously but above that it stops before 4GB.

Thank you for this info.  How about 1720 x 968 ? Its slightly less wide but a bit higher than 1880 x 800 and can easily be scaled since it is 16:9 ?

[mvejerslev]

How about 1720 x 968

Considered higher than 1880x800.. I can shoot a minute or a bit more in 1720 x 968, but its above the threshold for continuous so far.

Thank you. I was thinking of wiggling down a bit to slightly lowers speeds for cost savings, but based on your tests, I think that current ML raw development demands the high speed 1000x cf cards to get the maximum possible performance from the 5D mkII.

Thanks again.

I like the warning on the new build

Just testing the new June 10th built, it look like there is a little more speed
i have more stable  frame sizes as follows
5x crop mode
                     1920x872@24p =2777 frames
                     2048x820@24p = continuous
                     2048x856@24p = continuous
                     2048x872@24p =1500 Frames
                     2152x808@24p = continuous
                     2152x860@24p = continuous

Non crop mode
                     1728x972 @24p = continuous
                     1880x854 @24p = continuous
                     1880x940 @24p =1500 Frames
                  tested with  Lexar 1000x 32GB

Wow -- I'm seeing 70MB/sec on this build which is about 650 frames at 1880 x 1016.  Great work everyone.

a.d. / Alex, is there any way to enable 1806 x 1016 as a 16:9 resolution choice?  With the latest speed improvements, that might now be a continuous resolution for 16:9 on the 5d2.

Edit:  Ok likely not continuous -- I'm seeing 2300 frames at 1880 x 940, which is great.  If 1806 x 1016 is 1000 frames or better, that would be a great option.

Again, great work.

Okay, a follow-up question, - which of the 1000x cards is better for 5D2?

1) 32GB Komputerbay 1000x
vs
2) 32GB Lexar 1000x

Thanks,

M

[Hazer]

There's such variation card to card that I don't know that there is an answer to that question.  Personally, my Komputerbay 64GB 1000x is faster than my Lexar 32GB 1000x.  But for others it may be the reverse.

[siebenmorgen]

For me the 10th build is an improvement in speed. I can get about 770 frames in 1880 x 940 now on a Komputerbay 1000x  64GB. Great work! I' am so happy!

The Zacuto Monitor still doesn't show the right frame size and the position of the frame shifted to the left side. So, work with an external monitor is still very difficult. I hope this could be fixed.

Wait a minute... my latest speed optimization was 3 days ago... (1479df3+f884d7a+150a9c5)

Could it be this? https://bitbucket.org/hudson/magic-lantern/commits/61b6b1dc97a15a6c780cdae587a75679fc53aac3

Can you run a hg bisect to identify the changeset?

[a.d.]

1479df3+f884d7a+150a9c5
The 3 were already in last build, only 61b6b1d was not.

Is the edmac_memcpy, 150a9c5, fixed not for corrupt frames?

[Doyle4]

wow... so 10th's June seems be a big step forward again! Thanks guys who got back to me! sounds like a must have!

[siebenmorgen]

Sorry to say, that I don't know how to run a hg bisect. I am running the last version posted here: https://bitbucket.org/a_d_/magic-lantern/downloads  1222c61e8120.zip.

Works great! Except the Frame size and position in external monitor.

i got it working somehow )
but i find few quircks... average speed of h.264 is 50-54mbs and raw doesnt fo furhter than 35mbs 
how to record 1280x720 without crop

I have no idea, you have to find out

Don't forget that RAW unit of measurement for bitrate is in MB/s (megabytes per second) while h.264 is in Mb/s (megabits per second). 1 byte = 8 bits.

50-54 Mb/s video is only about 6.5 MB/s. RAW video pushes the bitrates on the 5D2 up to 60-70 MB/s!

Hi everyone!
I've got transcend 1000x 16Gb UDMA7 and ML benchmarks shows that it's capable of write speed up to 70Mb/s
In real action it shows no more than 58Mb/s
As I understand write speed depends on buffer size? And this speed/buffer size combination is unique for every card?
Is it theoretically possible to squeeze maximum from my card (this case 70Mb/s) by some sort of buffer size optimization or the only option here is to buy "legendary" Lexar 32Gb 1000x?

[plaxser]

Hi everyone.
I ran into problem while trying to convert some of the raw videos.
While most of them are easily converted with the latest raw2dng (10 june), three videos (shot on build 08 june) of my batch reported following error:
"File Supported Error: This ain't a lv_rec RAW file"
Is there any solution?

PS Thanks to all developers for their amazing work!

[scarimbolo]

So I installed the latest build on my 5DMK2, recording works just fine with a Transcend 32GB 400x (60MB/s) BUT
I'm experiencing one major problem: as soon as I drag the .RAW file (in this case 370MB) into the RAW2DNG.app, it says "file supported" but there aren't any DNGs in the designated folder that is created by the converter. 

has anyone had the same problem and got it solved?

Cheers, Alex

Got same problem  im using an older version that works great and also use RAWmagic which is nice indeed, iv noticed theres things you can do to get the latest RAW2DNG working but ill be honest and say i dont know much about terminal and how to code it to work, going to stick with old version and latest RAWmagic for now as there working great so far

[andyshon]

This new build (1222c61e8120) gets my write speeds up to 66.*MB/s, where as the last (d5a606e8c616) got me 63.*MB/s. At 1728x972 (25fps) thats got me up from around 700 to around 1200 frames before it hit's the wall.

Nice one chaps!

[cheguevara]

ok... i have not been clear enough its 50000 kbps so its about 47 mbps for h.264 and only 35000 kbps for RAW
anyway ill thnk ill do a low level format...
the other thing is how to rec 1280x720 without croped frame...

[silvertonesx24]

Is there any way we can save our settings in the raw module? It's great for experimenting now but for practical use it really would be beneficial to set up my preferred settings (rec button, resolution, sound sync beep on) and not have to reset them on each boot.
