What is the current status of compatibility of KB 128GB 1000x and 1050x with 5D Mk II? Is Magic Lantern bootable on these cards? Are they fast enough to record continuously MLV with sound in 1856 x 790 (or in higher resolutions)? I'm planning to buy one of these cards and I have found lots of mixed reports about them. Some claimed that they don't work, others they do...

Raw Video / Strange noise in audio recoded in MLV
July 05, 2015, 07:18:30 PM
Hi!
First of all I would like to thank everyone involved in ML development. What a fantastic piece of software!
And now let's get down to the business. Since I've started recording raws with my 5D Mk II I have strange problem with audio included in MLV file. At the beginning of the wav file (extracted with different versions of raw2cdng) I get awful noises. Sometimes I get this noises also in the middle of the whole wav file, which very often makes it completely unusable, especially when I record dialogs. Not every single file recorded is noisy, it happens more or less randomly, but mostly after camera restart or changing the CF card.
Here is the link to the sample noise from my video - https://www.youtube.com/watch?v=mSLVuziOsTI&feature=youtu.be
I found similar topic, but there were no answers - http://www.magiclantern.fm/forum/index.php?topic=13800.msg133275#msg133275
I use ML Nightly.2015Jan03 version on 5D Mk II. My audio settings:
Analog Gain: 26 or 29 dB
Digital Gain: 0 dB
Input source: L:int R:ext (my external mic is Rode VideoMic)
Wind Filter: OFF
Headphone Mon.: OFF
So how can I fix this?
Update: I have installed latest Nightly Bulid (2015Jul02) and I still get those noises. I have also tested MLV recodring without external mic and it didn't help.
Update 2: Mystery finaly solved: it's strange, but when I record MLV with sound on different CF card (meanwhile I have bought two Komputerbays 64GB 1000x) I don't get this awful noises. So my guess is, that the old card (Transcend 64GB 1000x) was not fast enough to record audio simultaneously, and from time to time generated those noises. On new cards I have also longer recording times in higher resolutions, so I think that the whole problem has something to do with a card speed.
