LiveView hacks (write speed improvement)

[ilia3101]

With these new hacks + overclocking + card spanning, 5D3.113 gives 3840x1536 14 bit semi-continously

Previously I could only get 12 bit for no more than 10 seconds.

I can't thank you enough!

Adata Premier ONE 64GB microSDXC. UHS-II. Rated 275MB/s, V90.

Okay, thanks, do you know if it switch to 48 MHz (drop to 21 MB/s) with 240 MHz overclocking after a while?
It is stable at 240 MHz?

SanDisk 170 mb/s sd card can only write 90 mb/s. maybe 300 mb/s card is needed for 99 mb/s write speed?

I am not sure, but there are more than one SanDisk 170 MB/s version, like:

1-SDSDXXY-128G-ANCIN --> Cameramemoryspeed.com claims it can reach up to 98.643 MB/s write speed.
2-SDSDXXY-128G-GN4IN --> No idea

I have to resolve problems with card access and loosing cam's bootflag first.

Overclocking in video mode doesn't work well for 650D.
Photomode gives 98 MByte/s max and no fallback to 20 MByte/s. Modules bench and sds_uhs loaded.
In movie mode numbers are much lower and 240 MHz does fall back to 20 MByte/s.
Additionally loading mlv_lite will give "malloc error: buffer=16777216" during read runs.

Hi there,

I am awfully sorry to sound like a total bozo... but I cannot get ML to load the modules. I get only 2, namely adtg and bench.
Tried multiple times, no luck whatsoever. I am not new to ML and all crop rec releases have been working fine, including the experimental ones.
This time around I can't figure out what's wrong. 

Running firmware 1.2.3

Thanks a lot, guys!

Hello,

Danne made some of modules (like crop_rec.mo/mlv_lite/mlv_snd.mo probably sd_uhs/dual_iso too) in his custom builds loaded by default and you can't unload/load them at your own, it's always loaded.

Go to "Movie" tab from ML settings and you will see RAW video and Crop mode are there (search for other modules, they will probably be in other ML tabs).

I think this time has come, could you make a build for 60d, I would try it myself, but I'm not a programmer)

60D card slot is limited to 21 MB/s write speed, and you can already get 21 MB/s write speed in LiveView. So the new hacks will not make any difference, unless someone get SD overclocking working on 60D.

I'm sorry being a bit off topic but i have a question

i'm trying with overclocking, these new hacks, card spanning, killing global draw,and i cannot get 14 bit for more than 3 secs (3.5K preset, 24fps)
The scene is exposed to the right, Raw module says 168mb/s required (lossless)

Is it better underexposing by 1 or 2 stops or stick with 10bit properly exposed to the right?

I'll 3 scenes from yesterday:
