MxR adaptor problems for EX1
I have been blaming SD cards for problems with corrupt files but seem to have have narrowed the problem down to the MxR adapters.
I sent one back and they sent me a new and improved one but still having issues that seem to follow the adaptor and not the SD card.I have been using Sandisk 16gb Class 4 SDHC cards in the MxR adaptors.
I was getting a lot of error messages in the middle of recording and on the new adapter I was playing back a long performance and it just stopped playing after about 5 minutes.
I also have a HoodMan adapter. The problem does not happen in the Hoodman adapter.
I find that the camera gets warm around the memory slots after it has been reading or writing for over an hour.
My theory is that the heat is effecting the MxR adapter somehow.
I have swapped slots and adapters and the problem follows the MxR after the camera is sufficiently warm.
More testing will have to happen to be able to totally confirm this.
I have ordered Transcend 16gb cards to see if they are going to work with the MxR adapter any better. -

Hi Ed,
I too use MxR, but was told to use class 6 or higher. I was told that anything lower than 6 would be too slow. As it is, you can’t do any overcranking with 6. I’ve not had any problems with the MxR except when i try to shoot at 60fps. Thats when I get the error message in the middle of recording. Anyway, let me know what you figure out!!

Ross of MXR (e-films) has said that Sandisk Ultras should work (Class 4 currently).
I’ve been using 32GB Ultra Class 2 for a year without issue but you can’t get them anymore.
I would not trust Transcend at all these days. Too many people are having issues.Sandisk Extreme (Class 10) or ATP ProMax (Class 6) seems to be the reliable choices these days but again Ross says he’s having good luck with Ultra Class 4.

This is not at all what I get from Ross or ALex. In a recent email they have told me that the Sandisk are no longer a good choice and suggest I buy Transcend. So I don’t get it. They are sending confusing messages.

I was told by them that Class 4 worked fine. I do not do any overclocking. Just straight HD HQ and HDV recording on my EX1.

I assume this is a follow up on your other post about Sandisk Class 4. Ross recently did some tests and found Sandisk Class 4 is OK. With EX1, I’d never overcrank on SDHC.
On the other hand, it appears Sony made major improvements to the USB handling in the EX1r and I’m hearing people have no issues going full on 24/60 with various cards (Extreme Class 10 is one of them but there are others I believe).

Hi Ed, I can’t comment on how hot your MxR is getting, but all electronic equipment will produce heat,including Sony’s SxS memory card. In our extensive tests, SxS memory cards will get warm to touch and so will MxM and so will other adapters we have tested. Heat dispersal will vary depending also upon the memory used. I’ve conducted marathon sessions of 48 hours non stop recording…with MxM using Hoodman Raw, ATP and SanDisk with a variation of 16GB and 32GB memory cards and all I was doing was formatting the cards on the camera when they were full. They were switching from Slot A to B without any issues and they were in the camera for that period and there was no media error, issues with recording, the files were fine. Yes they were warm but they were not hot…Regarding SanDisk, we have a database of clients who have been happy with SanDisk and have been using it for almost a year now with the original MxR and now with MxM and without any issues.
On our website we have recently added a new tab called Tested working media which compiles data which might be of assistance to you.MxM Express

Sony made the EX cameras specifically to use their S x S cards for recording media. I would not dream of using anything else. You are spending thousands on the camera and other kit, not to mention post production facilities, why economise on the most important bit, the media? You don’t need many cards, downloading files is easy and fast, even on location.

Hi Michael, re “Sony made the EX cameras specifically to use their S x S cards”, I disagree..the EX1/EX3 and the more recent EX1R, all are designed to work with SxS media however, they have a built in USB 2.0 interface. If Sony did not want anyone to use anything but SxS Pro media, they would not release equipment with USB 2.0 interface available, but only PCI-E. Sony’s own external recorder is USB 2.0 interface. Additionally, by having reasonably priced adapters to work with SDHC on the market, this was helping Sony sell more cameras and as well benefited you guys by having far cheaper SxS memory cards as time went by…The new EX1R has actually had it’s USB 2.0 interface improved by Sony and we are achieving results on par with the SxS. The older SxS was built on SLC platform whereas the newest SxS memory cards are built on a MLC platform which is the same platform as SDHC memory cards. SxS memory cards are prone to media errors as well. The fundamental problems is the consumer’s choice of memory card because not all memory cards are built equally. I do own a few SxS memory cards, but I never have had to use them because the adapters and SDHC cards are working flawlessly and the workflow is far easier to manage than SxS workflow. Yes, it takes longer to download the data to your PC but this is the only drawback…

[Michael Slowe] “Sony made the EX cameras specifically to use their S x S cards for recording media.”
Not quite true. Sony also made their external hard drive for the camera which is USB Express card based (and also can’t overcrank). With that firmware upgrade for the EX1 (EX3 was capable right out of the box) it became capable of using USB based devices. The problem is the controllers in the SDHC cards and issues with Sony’s implementation of the bus control.
Reports are that the EX1R can use an adaptor and good SDHC cards (Sandisk Extreme or ATP ProMax) and get full 24/60 overcrank.
My EX1, MXR and Sandisk cards have been without error from first use a year ago.
Even Sony now offers a memory stick option with the EX1R.

Well said Marek.
I’ll add that SDHC is affordable enough that you actually REDUCE risk of human error. You can buy enough cards that one no longer has to risk offloading during the shoot to clear cards. A huge number of errors I see here and on other forums are people rushing the copy and not checking in order to get a card back into service.
It’s affordable to buy four 32GB SDHC cards for nearly 8 hours of recording. On the other hand the price of four 32GB SxS cards would have put you well on your way (about half way) to buying another EX1 or a whole lot more kit to improve your production value.
