Requesting FeedBack on 1.6.245

Dear Friends,

Our latest Public Beta for the nanoFlash is 1.6.245 and we have a Flash XDR version out also, 1.5.92

We are requesting feed back on these releases.

In 1.6.245, with certain Delkin 450x cards, our MPG does not work properly.

We have made a change to support these cards in MPG mode.

In general, we are very pleased with these releases.

But, we need feedback from those who are using or have tested these releases.

We are very close to releasing a Production Level release, but we just want more feedback.

Any feedback will be greatly appreciated, if only to say "It works for me".

Works for me

The nano has been velcro'ed to the wall next to me, running off it's AC adapter, recording standard 1080i 29.97 the past week. 100Mb Long GOP to Transcend 64GB 400x cards, and one 32GB 400x Transcend card, which I've been using at 280Mb IFrame. SDI in and out. Embedded audio, sometimes 2 channels, sometimes 8 channels. Timecode is generated locally (in the nano), set to free run, synced to time of day and drop frame. Recording into mov containers. Primarily as a record machine, but some playback as well, mostly to check clips after the fact. Nothing plugged into the nano accessory port; everything is done from the front panel. (I still want you to put in a delay when pushing the stop button while the nano is recording, but that's for another thread). No timecode triggering, no cranking of any kind, no progressive segmented frames, embedded or otherwise.

The Transcend cards (32&64GB 400x) seem to hold up just fine at 280Mb, by the way, in both record and playback. I'm only using the 280Mb IFrame for the test signals card I carry with the nano (which turns it into a great test signal generator).

It all seems to be working as advertised. When recording, the "close file by pressing record once" works, as does the "skip to next card by pressing record twice". I have not had a chance to test hot swapping while in record yet. There was one time when one of the 64GB cards I inserted wasn't recognized, but a power cycle "fixed" things. I think this only happens when I'm first powering up the unit and putting both cards in almost simultaneously. I think the nano may be busy figuring out what just got put into slot one, and misses that something was also just put into slot two. Or not. I think it happened to me once before eons ago (over a year ago).

I'm using my nanoFlash with the latest Beta release. Signal from a Sony EX3 using Transcend 64GB cards. I've tested 50Mbps and 100Mbps L-GOP and 220Mbps and 280Mbps I-frame. No problems so far.

I do want to test it with a Canon HV20 using the HDMI input but haven't gotten around to that yet.

Cheers and thanks for the great work,
-Garrett

Dear Billy and Garrett,

Thank you both for the detailed feedback.

Pushing two CompactFlash cards in simultaneously may cause problems.

We just recommend putting in one card at a time, one does not have to wait long, just push one in, then the second one.

audio delay

I have just installed 1.6.245 and I am having audio sync problems there is a 3 to 4 second delay

I have an EX-1 set to 24p , I am monitoring audio from the nano and getting little to no delay, it is only

when I record that the delay happens

should I roll back to an older update

Dear Rob,

Where do you see the delay, in the headphones while recording
or in the files when you take then into a Non-Linear Editor?

We will attempt to duplicate this in our lab.

Thanks for posting the details: EX1 in 24p mode.

Could you please create a settings file for us:

Format a card, then navigate to

System|Create Settings.txt

Then press the right arrow, then press Ok.


Then email the files to CDSupport (at) convergent-design (dot) com

We will check out your settings, and test in our lab.

audio delay prob

Hi Dan,

I have only played it back from the nano to my IKEAN monitor .

I have not put it through my NLE yet.

Could this be the problem.

Dear Rob,

I am very surprised that the audio is out of sync in playback from the nanoFlash.

Yes, you can go back to a previous release.

If you are using Delkin 450x cards, you will need to stay on one of our latest releases, 1.6.245 or higher.

I have alerted our labs.

Dan,

I just played the clip on my Mac and there was no delay

so it must be only on play back from the nano

I shot this clip at 18mbs longop

and why I have you I just got the remote trigger and I was wondering what the proper procedure was

because the trigger starts the recording fine, but when I try to stop recording I find I have to hold the button

down for about 3 seconds before it stops the recording.

Is this normal

Dear Rob,

The 18 Mbps may be a clue to the audio delay problem.

The remote control works like this (in normal mode):

Press the Remote Control button, the nanoFlash starts recording and the Tally Light comes on.

Press and hold the Remote Control button for 1 to 2 seconds, then release, then the nanoFlash stops recording.

This prevents any accidental depression of the Remote Control button from stopping a recording.

We are trying to work in your request.

I am thinking that 1/2 second would be long enough to tell the difference between an accidental press of the Stop Button versus the intentional stopping of the recording.

Hi Dan,
I'm using the Delkin 32GB 450X CompactFlash Pro Cards in my NF version 1.6.245 recording mxf at 35Mbps and all, as far as I see is working well.

Is there a problem with the Delkin 450X cards with this beta version 1.6.245?

Thanks in advance.

Dear Anthony,

No, the Delkin 420x and 450x cards work fine in the nanoFlash, with 1.6.245 in MOV (Quicktime) and MXF modes.

Only in MPG mode is there a problem.

And we have already modifed our code to work with the Delkin's in MPG mode, we just have not released the new version yet on a widespread basis.

Hello Rob,

When you experienced the audio delay were you recording 24psf out of the EX1 or were you recording 60i pull down 24, via the nanoFlash 3:2 Removal?

Also note for everyone you can insert two Compact Flash Cards Simultaneously because of HOT SWAP support :)

Best Regards
