Serious problem with Nano at DVinfo.net

Darek Sepiolo · May 21st, 2010, 07:46 AM

I've got a serious problem with Nano. Once I finished recording few clips I've noticed that some are missing. Nano stopped recording them to CF card and left strange files on the card. Please see attached screen shot. All clips were recorded on SxS card without any problems.

Steve Brown · May 21st, 2010, 09:29 AM

Darek,

I haven't seen those, but I did experience something odd recently with my nano. I was using the previous firmware version (1.1.154). All clips and sub-clips were fine except for the very last one. The shoot was long format... over an hour of continuous recording at 100 mbps Long GOP. That last sub-clip is labeled as an .mov file, but FCP says it is an unrecognized file type and will not import. Interestingly, it plays from the nano OK.

I don't know if this could be related... just thought I'd add my $.02.

Hello Darek,
I've had the colour of gray from the NF and the only thing that "helps" you experiencing that is the connection cable to the NF (either HDMI or SDI). Please check your cables or replace them to be sure and try again. I had it with HDMI connection. Hope this helps.

Hello Darek,
If it helps I have recently seen a similar thing on further investigation it was found that the problem was caused by an intermittent connection caused by a cheap right angle BNC connector on the SDI input of the Nanoflash. (Not supplied by CD)
Since I have discarded the connector I have not had any further problems.

Darek Sepiolo · May 25th, 2010, 03:11 AM

Thank you for your comments.

I'd also like to hear a word from CD. Dan?

Dan Keaton · May 25th, 2010, 07:03 AM

Dear Darak,

What firmware version are you using? It is reported in the System|About menu.

Do you get a message on the nanoFlash that reports "Intermittent Source"?

Are you using a quality 75 Ohm HD-SDI cable with 75 Ohm connectors?

We will be happy to help you. I will send you a private message with my phone numbers.

Anthony McErlean · June 28th, 2011, 06:02 AM

There is a five minute clip missing from my NanoFlash recording.
I was recording to MxM/SanDisk at the same time with my PMW320, so I do have the missing clip/s recorded to SDHC card.

Apart from the missing clip, I also have noticed there are a few seconds missing at the start, of another clip.

NanoFlash Firmware 1.6.248
I have this BNC Plug.
BNC 75 Ohm Elbow Plug to Jack Adaptor Greenpar Equivalent B37P28J999X99 37528 - Connectors Cables Specialists Ltd
The SDI cable came from Symbiosis and am using Delkin 32GB CompactFlash Pro cards.

I am going to plug the SDI cable directly into the the NanoFlash and not use the BNC connector just in case it had something to do with the missing clips.

Dan Keaton · June 28th, 2011, 06:40 AM

Dear Anthony,

If you have not reformatted the card, we may be able to search for the missing file.

Please send me a private email and we will attempt to assist you.

90 Degree BNC connectors have been know to fail, but it is way to early to blame the connector.

It is certainly valid to remove it and run some tests.

How are you trigging the nanoFlash?

Does the missing file playback from the nanoFlash, if you still have the card and it has not been reformatted.

What brand/type of CompactFlash card are you using?

What Bit Rate?

Anthony McErlean · June 28th, 2011, 07:09 AM

Hello Dan.

Yes, I still have the CF card with the clips on it.
Trigger TC (Starts/Stops when camera record button is pressed)
MXF files at 35mbps.
Delkin 32GB CompactFlash Pro cards

Not sure I understand your question Dan.

OK Dan I will email you, thanks.
The missing clips were thankfully recorded to SDHC card but if you want to try and recover the missing clips from the CF card thats fine with me.

Thank you Dan.

Dan Keaton · June 28th, 2011, 07:19 AM

Dear Anthony,

Thank you for the update.

I was asking if, when you reinserted the CompactFlash card into the nanoFlash, will it play back the missing file?

You could use the Play menu, and select the filename of the file prior to the missing file, then press play.

Then if the nanoFlash plays the selected file, then the missing file, then we will know that the file is on the card.

Andy Mangrum · June 28th, 2011, 10:55 AM

Hello Everyone,

To recover Files from a Compact Flash Card, I would suggest to first try using KLIX it can recover all of our various file types (MOV,MXF,MPG) in the unfortunate event of a format, (Within reason of course) but it works very well,

Digital Photo Recovery Software: Digital Picture Recovery, JPEG Recovery, Lost Picture Recovery, Recover Lost Images

I'll try that Dan when I get a mini HDMI cable.

Thanks.

Anthony McErlean · July 4th, 2011, 10:08 AM

Hi Dan,

Everything up to Z101 7001 is recorded.

A few seconds are missing from the start of Z101 8001

My next clip is Z101 9001. A few seconds are missing from the start of this clip as well.

There is 4 or 5 min clip missing between Z101 8001 and Z101 9001

Hope this helps.

Dan Keaton · July 4th, 2011, 10:19 AM

Dear Anthony,

I would like to break down the filenames

UUCCCFFF

UU = Unit ID (Camera number or nanoFlash number)

CCC = Clip Number (automatically incremented at the start of each new recording

FFF = File Number within the Clip, always starts at 001

I will separate your filenames for clarity

Z1 017 001

Z1 018 001

Z1 019 001

A few seconds missing from the start of Z1 018 001. How long was there between the end of Z1 017 001 before Z1 018 001 started. Was there enough time for the nanoFlash to finish Z1 017 001?

The same applies to Z1 019 001.

It appears that the nanoFlash was not triggered, reason unknown at this time, for the clips between Z1 018 001 and Z1 019 001.

I can tell from the Clip numbers, 017, 018, and 019, that everytime the nanoFlash was triggered, it recorded.

Andy will be reading this post and possibly commenting tomorrow.

Anthony McErlean · July 4th, 2011, 10:30 AM

That was quick Dan :)

I will try and get that info for you.

Thanks.
