I don't know a whole lot about the internal workings of the camera, but to me that looks like it means that the controller isn't as limiting as initially thought.
I don't know exactly what is the bottleneck here. Does anyone know why there is a discrepancy between playback and liveview mode in the benchmark? Is the CPU limiting? Might be. When you turn an Global Draw the achievable transfer rate decreases from 65 to about 40 MB/s.

I still have two weeks to send back the Lexar 1000x an get a Lexar 800x instead. It costs less than half the price.

hi ladies and gents.
first time poster here.
loving and appreciating shooting raw.
my utmost gratitude to you guys.
now that's out of the way.

i was using an earlier build (last weekend perhaps?) and i managed to reach the 4gb limit on my transcend 600x card several times.
shooting at 1880x840

now with the may 16/17th build, i can't even reach 200 frames without frame skipping even if i shoot at 720.
i dont know if its the card or different build, but something to consider.
i honestly couldn't tell you which earlier build i used.

Did you deactivate Global Draw?

Another first-time poster -- thanks for having me, and thanks for all the hard work here.  The shackles are coming off quite unexpectedly here.

Running a Lexar 32GB 1000x card on the 5D2.  Tried a couple different builds including the 17th -- performance is similar across all of them.  Seeing write speeds in the 59-60 MB/sec range.  Occasionally it will drop below this and record a few hundred frames less before buffering out, for reasons I haven't been able to pin down.  Here's a quick rundown:

1880x720:  I can record indefinitely.  Pretty reliable.  However, this aspect ratio is really too narrow for my purposes.  I need 1080 / 16:9 for a current project, and when scaled up and cropped to this, it's not dramatically better than stock H264.

1880x840:  Much longer record times -- I've seen it go over 1000 frames before buffering out.  This is still a touch soft when scaled and cropped to 16:9 but it's an improvement over stock.

1880x960:  This looks pretty great even when scaled/cropped.  However, shortest and least reliable record times.  I max out at 381 frames before buffering out.  Frequently dips to the 250-300 region on some takes, even on empty/formatted card.  If I could do better here, I would totally use 960 for everything.

Silvertones, you mentioned a couple pages back you were getting 640 frames at 960.  That would be great.  Are you still getting those record times?  Have you done anything particular to enable this, or do we think it's the Komputerbay card?

Thx

@Hazer: You are doing 1920x on the 5D2? 1880 is the maximum width on the 5D2. Are you using a 5D3?

Crop mode goes to 1920 and even higher. You can zoom in with the AF point selection button to record in that mode (at the upper right-hand corner, within thumb's reach). Also note that its stuck at ~30 fps unless you change it with FPS override.

@vikaod:
Strange. 1880x840 needs 63 MB/s. Start LiveView and do a CF-Benchmark.

Ah, sorry -- you are correct, I meant 1880!  Definitely on a 5d2.  Will edit the above post...

Press the LiveView-Button on your DSLR.
Go to the ML-Menu Debug->Benchmarks->Card R/W benchmark

I just tested again with the May 16th evening build. Got 608 frames at 960, and 262 at 1080, with Komputerbay 32gb 1000x.

Problem for me is that these files don't convert with this build in raw2dmg, with all kinds of API version mismatches and ain't a lv_rec file

Ok that's impressive.  If I could get 608 frames @ 960, I'd be golden.  Is that the "e1d271904e4c" build from post #83 on this thread?  What kind of write speeds are you seeing on the LCD during capture?

That is the correct build. Somewhere between 62-67MB/s

Press the LiveView-Button on your DSLR.
Go to the ML-Menu Debug->Benchmarks->Card R/W benchmark

here you go. used both of my transcend 16gb 600x
so if im reading this right, my cards can't get past 56mb/s yet i've managed to reach the 4gb limit a few times.
strange right? maybe just a fluke on my end.

Exactly my thoughts... Seeing the better results in playback mode makes me think the CPU is limiting instead of the card interface. I am not sure if it's possible but a slight cpu overclock might help to do the job, but first I will look into the code to see if there is optimization possible.

Ok tested the "evening 16th" build.  I'm definitely not seeing your write speeds -- still in the high 50MB/s, occasionally 60MB/s.  But I can confirm the files can't be unpacked with raw2dng.  So... back to the 17th build.

Are you still getting 500+ frames @ 960 on the builds where you can unwrap the files?  Which builds?  If so, I wonder where the speed is coming from.

I just tested the May 17th build and got 518 frames @ 960. So, a bit of a step down, but not too bad.

That's pretty solid.  Were you able to unwrap the frames?  518 usable frames beats 0.  :)

Today I finally got my KomputerBay Professional 32GB 1000x CF UDMA7 so I tested it ...

1880x840 is about the best I can get.

I was, with the exception of one so far which for some reason was a jumbled magenta mess. I couldn't even make out what I originally shot.

I do have a new bug on the May 17th build, where the left side of the frame is black. Not sure what that is, I've linked a dng where this occurred.

5d 2 build 17 (dd53ca8bbeab) by a.d. in post #140
« Reply #196 on: May 19, 2013, 05:49:24 AM »
report on 5d 2 build posted by a.d. on post #140 on this thread, (dd53ca8bbeab.zip)

1. works good. extracts good.

2. crop mode has pink cast both at x5 and x10

3. audio recording works with separate wav file. on NLE i noticed 4 frame delay in 30p. (move wav file back 4 frames to sync.)

    in 24p there is 2 frame delay for the wav file.  ( move it 2 frames to sync)   

4. when I stop raw record by pressing LV again, canon record of h264 starts. so an mov begins upon stop of raw record.

I have just played with a.d.'s May 17th build and was very impressed, the features are showing up at an incredible speed!
The additional resolutions are a killer! 1600x840 seemed to work continuously without filling the buffer of a SanDisk 16gb 60mb/s card, strangely in the beginning 1880x720 would only give me 61 frames, after doing some other tests and running benchmarks it gave me 349 frames, it almost seemed as if the card first needed to warm up...other then that I can't understand the differnece in performance ???

I think I really like 1720x720, it just gave me over a minute and a half of almost perfect cinemascope aspect ratio footage, and I think this is easily upscaled to 1920x840 and will probably still look pretty good, I guess it is time to go out and finally shoot something with this!
