Thanks for those links, Renato.  I should have been more specific about the build question I suppose...

A better way of asking would be - what is the latest build that people have found stable in the wild?  I installed back in august so i know alot of work has been done since then around FPS override, minimizing pink frame, getting continuous, etc etc etc.  If I just grabbed the latest 'semi-stable' build would I be in good shape? 

Also, if I were to grab the ML nightly instead of the latest TL build  - what would i be missing out on, if anything?  I've tried following this saga but i'm not sure what the real functional differences are since most posts only allude to the differences or talk generally about 'the dangers' of TL and the politics of development.

Thanks!

Hi Everyone,

Been away for a few months but I found some time and got a 1000x card finally. So, i had a few questions (tried reading the whole thread but it's a bit scattered...)

1. I got a transcend 32gb 1000x - anyone have experience with these?

2. What is the latest stable build?  I'm talking continuous recording in 1x mode - minimal or no pink frames, FPS override working

3. I shot something yesterday and my last take crapped out during recording and now raw2dng won't unpack the .RAW file.  Is there a way to recover any dngs from this file or is it a lost cause?  I would normally let it go but i think it was a really great shot...

Thank in advance - and thanks for the work everyone has done on this project

@ 1%

Ahhhhhh....it's so (deceptively) simple.  Is that also why you always hear that the 1920 H.264 files are only really resolving ≤ ~1k horizontal lines?  Because the final output is simply an upscaling of the line skipped video feed? 

Somewhat related - I'm assuming that magic lantern is grabbing the raw feed after the line skipping/binning process and the possibility of getting further upstream and doing a cleaner downsample is not possible right?

thanks again

Sorry if I'm beating a dead horse but why will the 7D never make it to 1920x1080 at 1x? You said:

'In 1x its probably not going to get any bigger... but a CF camera should record 1x no sweat.'

How do you mean 'a CF camera'?

Thanks!

@alsey7

If you're referring to the vertical lines - try disabling highlight tone priority, low iso noise reduction and long exposure noise reduction.

Hbr suggested this and it seems to have solved it for me.   On the other hand now i'm getting hot pixels in the shadows...

I was having the vertical lines issue but Hbr's advice fixed it ( disabling highlight tone priority, low iso noise reduction and long exposure noise reduction).  Now though I'm noticing the hot/dead/stuck pixel thing. 

Mainly hot single pixels evident once recovering shadow detail in ACR....is there something in camera that usually filters these out that's being bypassed?

I've had the lines issue from the beginning - its present in 2.5k crop mode as well as the full sensor capture (though with the full sensor footage there's also what looks like a downscaling pattern on top)  Anyone know what's causing these?  I was even getting some extra burned in patches where the lines are stronger - is this just the state of my sensor?

Hi Everyone,

Been reading through these forums for a few days now and I've successfully gotten ML installed and the raw_rec module up and running at 1600x600.  I've been pixel peeping the footage a bit and while it's really impressive I have noticed a few things. 

All footage suffers from a particular noise in the shadows that shows some vertical banding - not that attractive.  As far as I can tell this is down to the Canon sensors and is present in all ML raw footage I've seen - including well-shot 5D mark iii footage.  Is there any improving this or are we down to the capabilities and/or limits of the sensors?  I might start exposing to the right a stop to combat this (is that why there's an ETTR feature in ML?)

More importantly I've noticed what i can only describe as a parquet-floor pattern in some of my shots - almost like jpeg-style compression.  Is this a result of some ML setting or is it due to something with the 7D?  Should I be modifying the bit rate or something when I shoot?  I also saw that people were changing their photo quality to S2( small - not fine jpeg) in order to get more frames fro silent picture burst.  Is this affecting the raw quality at all?

FYI i'm using a sandisk extreme 16gb 400x, the thomas worth build of raw_rec.mo, and problems are present in both silent picture and .RAW files....

Thanks
