I beg your forgiveness! I repent for my inconvenient question!

Bilal, do you have any plan about releasing that code?

Hi Danne! Do you plan to implement on the Eos M the mode Bilal is working on? 1736x2214 @ 23.976 FPS with full real time preview?

With this new build everytime I stop recording (in any mode) my camera freezes on some weird screen. I have to turn it off and back on to make it work again..

Also, it seems that 14bit depth is no longer usable, after a dozen of frames the recording stops. Only 10bit mode seems to be really usable. And my sd got 92mb/s in the card benchmark.

@Mattia I'm doing all the testing in Windows, every multicore processor should benefit from this (the more cores, the more benefit most likely)

When will you release an updated version on the website?

Ok so, tested uncompressed cDNG export for a lossless 14-bit 1x1 3584x1500 Dual ISO MLV clip (on i5-8500, 6-core) with 5x5 chroma smoothing. Here we go:

• Official 1.14 release: 1.92 s / frame
• ilia's 330563 commit with Qt6-llvm15: 1.79 s / frame
• iaburn's 254ad90 commit with Qt6-llvm15: 0.75 s / frame (1.3 fps)
  

A nice 150% increase in export speed!

Congrats iaburn and all.

Still have to check exported DNG quality, didn't have the time. Will update this post in 12h time.

Is this increase only on Mac? Any chance for the Windows version?

I made some weird discover in my tests of the new build, a nice one actually: in 3k mode, 14bit, at 2.39 aspect ratio the recording slows down and then stops after few seconds. At 16/9 aspect ratio is continuous.

I have tested. All crop modes benefit from it. The higher the resolution, more laggy it would be but thats normal and still significantly faster. I use 2.5k, 2.8k and they are almost same speed as real time preview. even 5.2k is now totally usable.

Ok I made some tests and the 2.8k 10 bit looks almost real time, as bit depth or resolution increases the refresh rate decreases.. Could it be partly because I'm using an old and slow sd card? What card are you using?

It doesn't really seem almost the same as real time to me.. Actually, I didn't notice any change on the 2.8k or 3k modes.. What settings/hacks are you using?

- Optimizing grayscale preview while recording with framing.

Do every preview benefit from this commit or only the grayscale ones? A faster framing preview on all modes would be a game changer.

Could anyone share an updated build of Mlv app for Windows?

Hi Danne! Thanks for your builds, I think they're really great! I have two questions I would like to ask you to better understand how ML works:

- In one of his videos Zeek says that 5k resolutions are actually recorded at a lower resolution than HD and then upscaled internally. Are there any other video modes that work this way? If so, what's their real resolution?

- I've found a formula on reddit to calculate the precise crop factor for any video mode. The formula is: 5184 / (selected horizontal resolution) * 1.6. Is this formula correct?

Let me know and thanks for the work you do!
