Codec Error
 

On a job out of town and on the second day of shooting, our nanoflash displays "codec error." It worked flawlessly the first day and no settings have changed. I have swapped out my cards and reset the nanoflash but still get the error.

Re: Codec Error
 

Are you sure you don't have some kind of mismatch between what the camera is outputting and what the Nano is set to accept?

Re: Codec Error
 

Dear Mike,

Based on previous experience, I assume that you are shooting on a Sony FS100.

And you have the HDMI output set to 1080p, please set it to 1080i.

While this is completely counter-intuitive, the 1080p setting outputs 1080p60 over HDMI which is too much data for the nanoFlash, resulting in the codec error.

When you set this to 1080i, you will actually be outputing PSF (and not interlaced).
(PSF is Progressive Segmented Frames, which looks like interlaced to monitors, but it is not.)

Thus, you should use the proper settings in the Video Menu.

For 1080p29.97 and 1080p30, set the camera accordingly, then
please set Video|Record PSF>Prog

The same applies for 1080p25.

For 1080p23.976 and 1080p24, set the camera accordingly, then
please set Video|3:2 Pulldown Removal.

If you want 1080i50, 1080i59.94 or 1080i60, set the camera accordingly,
then uncheck the above menu items.

Dan:

I think a lot of us would really appreciate the posting of download files that are sorted by camera.

Those setup profiles could then be loaded onto compact flash cards to correctly set up the NanoFlash or XDR. It would take away a lot of the trial and error and confusion.

I know, I know ... read the darn manual.

Dear John,

Good Morning!

This is really a camera setup issue as we don't support 1080p60 in the nanoFlash.
We will in the Gemini 4:4:4, from HD-SDI, starting next week with our new firmware release.

But, we could create setup files for:

1080p25,29.97 and 1080p30
1080p23.976/24 when the camera is outputting 23.976 (23.98)/24 without pulldown
1080p23.976/24 with pulldown (so we would enable 3:2 pulldown removal)
1080i50, 59.94, 60
720p23.976/24 without pulldown
720p23.976/24 with pulldown
720p25, 29.97, 30
720p50, 59.94, 60

John, I think you have a good idea.

Re: Codec Error
 

The camera is a JVC Gy-Hm700.

NOTHING had changed on settings from the first day to the second day of shooting. The camera was set at 1081i 60 (.mov) feeding the nano via SDI and the nanoflash what recording it just fine. The second day we received the "codec error.

Re: Codec Error
 

Dear Mike,

Thank you for the additional information.

I have never seen a "Codec Error" message in any case other than when the nanoFlash was sent a frame rate higher than 1080p30.

Could you please call our Support Team, and we can trouble shoot this with you?

(I am leaving on a trip right now and will be out of touch for a while.)

Re: Codec Error
 

Dan - those downloadable setup files would be awesome!

Mike - one other thing to try is swapping out cables - sometimes they go wonky and cause problems - had that happen myself.
But by all means, call CD Support - they are wonderful. CD is the most responsive manufacturer we have ever dealt with - they truly take action that tells you that they know their customers are the boss. You won't be dissatisfied.

Re: Codec Error
 

I’m too am having problems with "codec error", but in my case it is with trying to record SD PAL in some configurations onto my Nanoflash.

My goal is to take 1080/50i files previously recorded with the Nanoflash (from a Sony EX3) and convert them using my Matrox MXO2LE to SD PAL. Viewed on my HDMI monitor (HDMI-out set on the Matrox to SD channel) those SD files look clean and crisp. An excellent down convert.

I tried connecting the matrox to the Nanoflash via HDMI, but the Nano refuses to recognize the incoming signal. The Nanoflash read-out (on the bottom line of the display) says “no SRC” and “codec errors” on the top line. But if I switch the Matrox video out to HD, then the Nanoflash happily recognizes the incoming video as 1080i.

So I tried recording that SD stream onto the Nanoflash using an SDI connection instead. This time the Nanoflash accepted the SD stream but the resulting files looked soft. About as soft as exporting those HD files from an FCP timeline as prores PAL. Not particularly good.

So my two questions are

1. Why does the SD-SDI stream when recorded onto the Nanoflash look soft?
2. Why won’t the Nanoflash recognize the HDMI SD stream?

I should add that I normally output SD-SDI from the ex3 and record direct onto the Nano using an SDI connection and the results are fine.

still waiting for an answer here... i hope it will be OK with the next promised after NAB firmware,look here:

Re: Codec Error
 

Ah, I'm not alone!

Thank you, Samer, for the link to the thread. I am on firmware 1.6.248. So all is now explained. i'll try a different firmware when i get the chance, and keep in touch with developments.

Re: Codec Error
 

I believe there is a limit of 3 firmware upgrades per unit. If you go beyond that, you're then officially stuck to that firmware unless you send it into Convergent.

Re: Codec Error
 

Oh dear! Well, I decided anyway to return the firmware to vers 1.6.29 as Samer's link suggested. That's my second update. One to go!

This time the Nanoflash did recognise my SD signal from the Matrox. But only if i set the HDMI out in the Matrox preferences to YUV. Wouldn't recognise RGB native for some reason. I made a recording but all the colours were back to front, and something weird happened with the sound. But I could see enough to confirm that there was the same softening of the image as when I recorded via SDI.

But I would like to know why the Nanoflash appears to soften the image when recording Standard Definition.

Re: Codec Error
 

Dear Friends,

I have been traveling so I am late in responding.

There is no limit on the number of times one may update the firmware in the nanoFlash.

And you may go directly from any firmware version to any other firmware version. One can install a previous firmware version, if desired.

Re: Codec Error
 

Dear Richard,

The nanoFlash will only record a signal, if it is in one of the "Camera" standards as opposed to non-Camera standard signals which are common from a Computer.

If you computer can be setup to output one of the "Camera" standards, then we can record it.

The image size must the correct, and the frame rate must be correct. And it must not be RGB.

We support SD and HD.

Also, the nanoFlash will not soften the image. What nanoFlash options were you using?

MOV, MXF, or MPG?
Long-GOP or I-Frame Only?
Bit-Rate?

Proper Downconverting of an HD Signal to SD is a complex task.

Not all HD cameras output a great SD signal.

Re: Codec Error
 

Dear Richard,

The nanoFlash does not support SD over HDMI.

We did not implement recording SD over HDMI as this is rarely requested.

Re: Codec Error
 

Hi Dan, after more than a year i got the answer here from you :-) ..(i still think you give the best customer support and i thank you for that)
http://www.dvinfo.net/forum/converge...1-6-248-a.html

are you saying that the sd recording option from HDMI was deleted with the last firmware?,is it something that you can add with the new firmware or it is something definitive?!
i remember it worked well with the earlier firmware,but i think if you need space to add other more important things than supporting sd via hdmi, it's not a big deal...it would be nice to have it and i know that nanoflash gets better and better with every new firmware...
thank you for your time
Samer

Re: Codec Error
 

Dear Samer,

I try hard to provide accurate answers to the best of my ability.

These are based on my knowledge of the nanoFlash and/or Gemini 4:4:4.

Sometimes I do not remember an important detail.

For example, I do not remember our nanoFlash ever supporting SD over HDMI, in or out.

I was not aware that any release prior to 1.6.248 supporting SD input over HDMI, but your earlier post indicates that this was possible.

To the best of my knowledge we did not intentionally take out this feature to make room.

I can ask our team tomorrow.

Re: Codec Error
 

Message deleted.

Re: Codec Error
 

Dan has since corrected me in saying that it is not true, however, when you go into the "About" screen of the nano, it will show something on the lines of 3 REG and 3 UPD remaining. Those numbers should stay the same if there is no limit.

Re: Codec Error
 

thanks Dan for your reply re my perceived softening of SD when recorded on the nanoflash.

To answer your questions ...

the files in question have originally been recorded on the EX3 as 1080/50i, via the Nanoflash which is usually mounted on the camera. So the files are XDCAM 4:2:2

FCP timeline is set to 1080/50i Prores HQ. This is passed through the Matrox MXO2LE box. The image I observe on my HD monitor, connected to the HDMI out (set in the matrox preferences to SD) is good, sharp (for an SD signal) and clean.

Now I want to down-convert the files to standard definition (PAL). I set the SDI output of the matrox to SD channel. I connect the SDI out of the matrox to the SDI input of the Nanoflash and record SD files. When i replay those files on to the same monitor, they look softer than straight through the Matrox.

The Nanoflash is set to .mov at 50Mb/s. I've tried both long-gop and intraframe. Same result.

I'm not so worried about not being able to record SD from HDMI. That was just an experiment. Nanoflash is normally always connected thru SDI.

Am I doing something wrong? Is it that i've set the timeline to prores and it should be XDCAM?

Re: Codec Error
 

Dear Richard,

When recording the downconverted signal, please monitor the images to check for softness.

Then playback the files recorded in the nanoFlash, by playing back the files in the nanoFlash.

(But this may not be possible since you may only have an HDMI monitor).

This is the test to determine if the images are soft.

But, if this is not possible, please load the nanoFlash footage into your NLE, keeping it in an XDCam timeline.

I hope this helps.

Re: Codec Error
 

Thanks for your reply, Dan. I'll try your suggestion in a few days when i have access to the camera again.
