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.

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.

Thank you for your comments.

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

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.

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.

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.

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?

Hello Dan.

Yes, I still have the CF card with the clips on it.

MXF files at 35mbps.

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.

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.

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 (http://www.joesoft.com/products/klix.php)

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.

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

Thanks.

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.

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.

That was quick Dan :)

I will try and get that info for you.

Thanks.

Dan.

Info from Clip Browser as I recorded to a MxM Combo simultaneously


End of Z1 017 001 to Z1 018 001 .......17 seconds in between.

Looking at the clips in CB there seam to be two clips missing from the NF.

My next MxM clip starts 10mins after Z1 018 001 stopped, the NF didn't record this.
This clip duration is 12 seconds.

1min 03 sec later another clip is recorded to MxM card lasting 4min 45 sec
The NF didn't record this.

About 7 mins after that another clip lasting 2min 51seconds was recorded to MxM card.
The NF recorded this but missed the first 13 frames.

I recorder to NF for the remainder of the day but didnt check out anything else.
I just went with the MxM cards after that.

Hope this helps.

Hello Anthony,

Where you by chance rolling the timecode from 23:59:59;59 to 00:00:00:00 when the first error occurred?

Secondly what type of camera and format were you recording? So i can try to replicate this in our lab, (Example Sony EX3, 1080p25 100Mb Long Gop QT)

Did you have Timecode Trigger Delay activated? Which may account for some of the delay or missing seconds, this is found under System>Timecode, but if this was activated every new file created would have the same delay at the start,

Also could you double check that the timecode on the nanoFlash Files match to the natively recorded camera files,

Lastly did you try KLIX to recover your Compact Flash Card, if you are unsuccessful, you can always send the card to us,

Best Regards

Hello Andy,

I didn't bother with to many settings in the NF, If I get it to do what I want, I just keep it at those settings :)
So I'm not sure what rolling the time code is :)

I have a PMW-320
Trigger TC (Starts/Stops when camera record button is pressed)
MXF files at 35mbps
Delkin 32GB CompactFlash Pro card

Timecode Trigger Delay activated.... I dont think so but will have a look.

timecode on the nanoFlash Files match to the natively recorded camera files.....I will try and find that out for you.

did you try KLIX to recover......No Andy I didn't. I have the missing clips recorded to SDHC card so I'm not to upset about it. Might be more worried if I didn't have them I suppose.

I dont know what caused this to happen, I'm putting it down to this BNC connector.

Do you thing the missing clips are still there btw?

Thanks Andy.

Hello Anthony,

As for the missing clips it is hard to say, you could run KLIX and if the files were recorded it will find them, but it the nanoFlash was powered off while recording, the current file being recorded will be lost,

The Issues you are seeing may be due to the BNC connector, but I will run some test in our lab tomorrow to see if I can replicate the issue,

As for a Bad BNC elbow in theory we should start recording and if we loose the signal we will close the current file and start recording again once we have locked to the SDI,

Do you remember seeing any Error Messages such as "Lost SRC" or anything?

Best Regards

Hi Andy,

Thanks for taking the time.

Its either the BNC connector or the SDI cable.

Sorry, I didn't see any error message at all.

Thank you again.

Hi Andy

I'm work on a different project and just noticed 5 or 6 seconds missing from the start of another NF clip.

In this case it doesn't matter if its missing or not because I'm trimming it anyway, but it is missing none the less.

Just so you know, The clip before this one lasts 13.08 seconds.
3mins later I start recording again, this clip lasts 11.13 seconds, about 5 seconds is missing from this clip.

This was all recorder without the BNC connector. (i removed it because of the missing clip from my last project) So I cant blame it this time.

Andy you asked ...Did you have Timecode Trigger Delay activated..
Dont think so ...its sitting at 0

Hello Anthony,

I would suggest to do a restore defaults, This is found under System>Restore Defaults

and then only change the trigger to time code trigger, This is also found under System>Trigger >Last TC

If this works with no missing time, (at 100Mb Long Gop then I would Try 35Mb)

Best Regards

OK Andy,

I'll do that but I'm out recording at the weekend again,
I would normaly use MXF files at 35mbps to use less of the CF card.

Thanks.

by any chance do you have Picture Cache Record set to 'On' in the camera?

Hi Dave, sorry, just saw your post.

No, its turned off.
