Thanks @a1ex for the white level links. Put it up on todo list. Hopefully someone might dig into the issue.

New upload experimenting with void FAST hack_liveview_vsync() in mlv_lite.c. There´s so much interesting code created by a1ex and g3gg0 it never seems to end. Anyway I used this part to get real time preview while camera is in raw idle mode(standby not recording). Works by pressing halfshutter when using following presets:
    "3K 3032x1436",
    "4K 4038x2558",
    "5K anamorphic",(default setting)

Good for setting focus beforing hitting rec. Before the only way was to use framing mode. Also added for 100D.

What exactly is the difference to the version before? When using 5K anamorphic, it looks the same for me... or have I forgotten to setup a parameter? (picture gets greenish touch and y axis is stretched)

I changed the default preset "anamorphic" so it wouldn´t give real time preview other than in 2.35:1 and 16:9.
The bigger use is with 3k and 4k since they are totally dependent on framing preview when both in idle and while recording. Now at least we can zoom in with real time(cropped) preview before recording.

Is there any way to "unstretch" realtime preview in anamorphic mode, or is it impossible because of register settings? It is very hard to focus with it (okay... it is better than framing, but...) :)

Well. A1ex has some thinking about what and where to look for this kind of reg manipulation. If there´s any solution I don´t see how it would be done in real time live view other than maybe when setting focus before hitting record.
In this hack by the way it´s actually possible to modify regs while recording but of course you will get corrupted output while focusing. Maybe if this hack was done while pausing recording it might be a start for new achievements  :P

Comparing these modes: Mv1080p vs 5k anamorphic

Apart from the difference in resolution, which mode has the best image quality? Which mode has the least artifacts?

You could easily do some testing on this and find out real quick. Also maybe even post your results.

My tests today show that the mv1080p mode is more detailed. With the mlvapp v1.5 I don’t see much difference anymore in artifacts betweeen the two modes. But it could be the weather conditions. Lots of smog today which results in low contrast. Before I’ve noticed a fair amount of aliasing with the mv1080p mode in sunny conditions.
I’m asking because I don’t know if it is the weather conditions or maybe the new mlvapp version that gives different results. And I was under the impression that the new 5k amamorphic mode would yield better results (Less aliasing and better image quality).

Please upload short example files. Easy to shorten in mlv app.

- Reverted a reg for anamorphic 2.35:1
- Yesterday commit(preview capability in idle mode) only to work when preview set to 'framing'

When using 2.5K and pressing halfshutter the liveview shows some kind of modern art and I have to go back to ML-menu, press menu button to get it back normal. Same for 3K, 4K, 3x1 modes. mv1080 and 5K anamorphic modes are working when doing the same. mv720 mode seems to have wrong framing (1.67 stretching missing?), but does not have the bug descibed above.

4.5 anamorphic seems to record corruption free here. No single corrupted frame so far. Great.

2,3,4,5k modes needs to be in x5 zoom. Only 2.5k has realtime preview while recording. 3k, and 4k works best with framing set...

Generally to switch modes it is safest to enter and exit ml menu for all regs to settle.

Yes, I do so. Framing is on and I enter and exit ml menu. But as soon as I press halfshutter, I get this problem as described. How can I activate x5 zoom? I thought this is activated automatically?!

Cannot reproduce. Just tested the latest version. Can you try redownload again and see if it works better?
More users? Working or not in this build?

Still the same. Choose 2.5K preset, quit menu, halfshutter, voilà. After going back to ML menu, resolution, fps and crop factor looks weird too. Press menu button and all is fine again.

It says that you are not in x5 mode. If you exit menu from ml menu it should refresh the patch.
You can manually enter x5 zoom by pressing info button until you get the magnifier glass. Push that twice.

Yes, that works too. But I thought having used 2.5K already focusing with halfshutter... maybe I am wrong.

Hard to fully understand but if it works when in x5 it's alright. X5 can be lost by entering canon menu and back and if so entering ml menu will refresh the preset again.
The semiautomated x5 stuff I implemenred is really a hack. I wish I could do the presets lik a1ex done them for the 5d3 but I lack knowledge here.

But even after manually entering x5 zoom - as soon as I press halfshutter I get again this "modern art" screen. This does not happen for you?

Actually not.
Could you try and disable all global draw stuff and only keep it on for Liveview so global draw is still on? I suspect some interference from histogram or similar.

I completely disabled Global Draw and all other features on this tab. Restarted camera. Switched some modules. Restarted camera. Nothing helps. No idea what I am doing wrong or different.

Hm, strange. Sure you are testing the latest? I put up at least two versions today with the same name.
If you are in x5 zoom and framing is set it should work.
If I use canon menu button I get what you are describing. Sure you are going through "ml" menu? They are not the same.
I need to change the description for this in preset menu I notice since it says canon menu button in there which is wrong.
