Tragic Lantern for 6D

4gb limit is not in the module.. if something happens with memory then it stops... files bigger than 4gb I'm having a problem breaking up still but it will do it. I recorded a 27gb  file yesterday.

Wowzer!

I wonder what is changing performance for me. It's like the first attempt after a re-boot is always a bit crap but then it kicks in the second time and works fine.

Good work anyway man and thanks for the url link!

By the way - only point in mentioning the limit was just pointing out that I seem to have randomly returned to getting longer recordings at 1504x640

Try using 640x480 overriden and either raw or L quality. When in doubt check memory menu and make sure you have 30 mb chunks and 152MB total

new discovery. Selectin sraw and no jpeg makes mem allocation fail (or whatever it's doing before it records).

Basically it makes it not record.

[noisyboy]

same with mraw

[teo770]

yes, no RAW at all !

RAW (as in max quality) works for me just not the lower two raw quality shooting modes.

Just tried this for you with 1536x640 selected on NTSC 640x480 overridden to 24fps with every different photo shooting quality and have the following results:

RAW and every jpeg option gives me about 1,300 frames apart from Jpeg S1 (high quality) which gives me about 1,500 frames before skipping any. Ran all of them again just to make sure and had the same results again. Jpeg S1 (high quality) definitely gave me longer (if only by a few seconds) performance.

(global draw off).

Where do I find this dude?

Those MRAW/SRAW modes reduce memory... look at it. Its in the debug tab like 400K + 2000K. Select to see shoot malloc.

Raw and S1 or L or S3 all 152MB... any increase would be from reduced cpu usage... which we can't see (cpu meter broken).


720 vs 1080 vs 640 should all be different as YUV buffer is going to be different. 720P actually shrink the vertical height and so does zoom mode. 1080 vs 640 the raw image is the same but the HD buffer is remapped to 640X480 so seems a little less intensive on the camera.

On 600D gains from sraw and using lower res are really noticeable because its more resource poor. Ie raw or L or S will give you 70MB only and sraw gives 100MB.

Ideally we want to take YUV buffer and any other edmac down to 1 line when recording then it should be faster and free up some memory. But this part isn't figured out yet.

[noisyboy]

With 720 60fps selected and overridden to 24 fps - 1536x639 (coz can't select 640) will give me up to 1800 good frames so better performance there.

[teo770]

Almost there !

1504x640: 37.3 MB/s => 47 frame drops during 4GB record !
1536x600: 36.9 MB/s => no frame drop at all
1840x500: 36.8 MB/s => no frame drop at all

Two way: wider or higher....

The problem know is only about cards speed.... remind me GH2 old times !

In the benchmark, could you add buffer=8192k read/write test please ?
and even buffer= 30720...
Still playing with cluster sizes in my exFat SD trying to find extra 0.1 or 0.2 MB/s !

Next week i'll receive my new sandisk 128GB 45MB/s, will bench it too.

[exflyer]

a quick test
Raw - off
Jpeg - S2
video 1280*720
FPS override 25
RAW video 1840*540
SDHC SanDisk Extreme Pro 32 Gb
get about 300 frames, then dropped frames

Wow, picking the "other" resolutions in adobe raw they don't look so bad. 2048*889 is passable out of 1152x500

Sweet! Have you figured out how to choose them in AE yet? I can select them in PS but that's looooong.

Also (sorry - continuing my moire/aliasing obsession here). Is the sensor the same in a 6D as a mk3? Are we getting screwed due to a different sampling method or is the hardware just not up to scratch? I just noticed on some mk3 vs 6d footage that even though the mk3 footage looks like there is no moire and aliasing in comparison, it does seem softer. As if the mk3 footage goes through a guassian blur or something. It's really standing out to me on raw footage and I'm convinced that it's because there is no codec softening the image (which to be fair was never that fantastic in terms of moire anyway).

[noisyboy]

Also - noticed the [113] Module Refactor .zip

Worth getting?

Yep.

I can dig it

Update: recording times seem significantly reduced for me in this version for some reason. Loving the new start record method though

[1%]

Did not seem reduced... just stops when buffer gets full instead of skipping.. there is a setting. Still getting 4*30 buffers and seems to be writing at same speed.

[teo770]

Agree with Noisyboy, even 1504x600:34.5MB/s (continuous shooting before) stops or frame skip after around 1GB
Very nice start/stop function guys !!!!

Buffers seems to have grown: 4 x 32 ?
And in every resolution, recording display less MB/s. Normal ?


Toshiba seems to have a new 64GB SD card annoncing 60MB/s write speed:

Love the new feature with LV button, its great!

1%, could you make this white cropmarks box which is visible during recording to come out earlier just when "READY press LV button to start recording" appears? There will be easier to get a subject into a frame properly.

Does 6D have 1:1 crop with any resolution or zoom? Somehow I cannot find any info about it, found only for 5d3.

[kgv5]

I've also noticed, that with the newest build write speed dropped a little bit. Before I had 37-38 mb/s, now mostly 35,2-35,5.
Now (freshly formatted card)
1504x600 ~1000frames
1504x640 ~400 frames
1534x640 ~370 frames

This "buffer full-stop recording" feature is great for me - don't have to look for the start of frame drops in post.

teo770, where is the thing to set memory card cluster size?

[teo770]

It's not in ML.

You can format the SD card either in FAT32 or in ExFAT
When formating in ExFAT:
- you get no more 4GB file size limit
- can use long file/dir names instead of FAT32's 8+3
- choose btw more cluster sizes when formating

I have 2 Sandisk Extreme Pro 32GB 95MB/s and testing/benching both in FAT32 and ExFAT with each update
For now, i can say you gain a few 0.1 to 0.5MB/s in the benchs.
The idea is the same: in ML higher buffer sizes offers higher write speed
Higher cluster size should offer higher write speed too.

My best shots are with a 4096k cluster size actualy.
But this is a TEST, i'm not recommanding exFAT yet, neither is ML team !

Thanks, yeah, I know it is not in ML, I thought that such an option is somwhere in EOScard. I have already exFAT, so is default cluster setting 4096k? If not - where can I change it?

[teo770]

You can change that only in formating.
When formating ExFAT, you can choose cluster size.
