7D may be described as an oddball in ML world: Dual processor design and therefore some features are still missing. And ATM there is no serious development to solve dual Digic 4 processor issues.
Don't hold your breath!

I see, thank you, i understand, old camera, not many people interested
i'm using Daniel Fort's magiclantern-raw_video_10bit_12bit_LVState.2019May15.7D203

It's quite good, 2.5k for about 450 frames,

I'm like this build for photos (rec trigger, half shutter pre only)
Silentpics: slow
Burst: good but low resolution (and many purple frames using crop)
Crop video: good resolution, no purple frames (but many useless frames)
Crop video + rec trigger: Good resolution, frames as needed

To speed up Silent Pics use MLV, not DNG. See https://wiki.magiclantern.fm/camera_help#silent_pictures

Storing into MLV is considerable faster than writing DNG. Example: 7D, burst mode (94 pics). Writing DNG: 80 seconds Writing to MLV: 24 seconds

Yeah, I'm using mlv, I mean the shutter speed, maybe I should buy a t5i and shoot 1 second of 4K and use as photo

Hi
Can anyone recommend a stable build for 2.5k on the 5D2?

Thx in advance.

Nope, that's not what Walter said. 7D has a very different hardware design than any other supported ML camera.

In general, features of given generation can be easily, often even blindly ported into other models.

7D has two CPUs, each run it's own OS and they communicate with each other. Think of it not like your dual core / dual CPU computer running Windows/Linux/OSX, but more like two computers linked via a very fast network. CPUs share responsibilities that in "normal" circumstances are done by single OS on single CPU.

Thus porting features to 7D is significantly harder, requires knowledge specific to that one model and usually having one in hands to test if given idea works at all.
