Hyperdeck Studio: Switch which SSD to record on

Is there a way that I can switch from recording on SSD 1 to SSD 2 without stopping. I want to switch before SSD 1 gets too full and starts to lose frames.

You should never lose a single frame when the Hyperdeck fills SSD1 and switches automatically to SSD2. If you are losing any frames... perhaps there is something else going on?

I have a Hyperdeck.. and regularly record shows where my recording crosses from one SSD to the other. Never lost a single frame in that process.

But... It would be nice to be able to press a button to tell the Hyperdeck to switch to the other drive anyway.

When I lose frames it's because of the SSD getting too full and slowing down, not during the switch. But I want to switch to the second SSD before the first one is full not let it make the switch on its own.

Are you using a certified SSD? This has never happened to me. The only way I know to switch SSDs is to physically pull it out while recording.

Hold the record button down for 3 - 5 seconds to switch SSD drives while recording.

Never mind switching... My first point still stands.... Your drives should have no reason to ever "slow down". Why should they do that as they are nearing the point of getting full? These are SSD drives... Made from solid state non moving parts. There is nothing in them that should ever slow down.

And... I've never heard of that technique to switch the drives. I'll have to give that a try...so hold the record button down for 3-5 seconds while it is already recording? Hmmm I guess I can see some situations where this could be useful. Thanks!!!

On the Sony cameras which uses SxS memory cards, if I pull out a card, the recording automatically continues on the second card (of course without a single frame dropped. Also when I use the recording in NLE softwares, these files will appear one file). This would be good on the HyperDeck too.

I have the same problem. My Hyperdeck loose some frames when switches between cards (I have too SSD Smasung 830 series) wich are recomended...

Do you have any indication on the Hyperdeck that it is losing frames (flashing red record light I think)?

OCZ Vertex 3 work great for me.

So, you think is the SSD brand? BlackMagic recomoends Samsung...

Yes, but one needs to use the Sony XDCam utility to do this as the SxS cards are written with metadata to allow this. The HyperDecks do things the "easy" way and just dump files, which are easier for the "average" user to import.

I LOVE the Sony utility but many "new" editors struggle with anything beyond "drag and drop". The idea behind offering DNxHD and ProRes WAS to allow quick "no import/transcode" editing, I believe...

Nop. It seem to be recording as usuall, in red. I did realise the problen in my studio, editing.

When it was nearing the last 20 minutes or so that I could have it recording on the first drive it started to lose frames. The rec button was constantly flashing. I want to be able to switch to another drive partly so I can dump the footage before filling it up. Say I fill up one card lets say for 4 hours. It takes that long to dump and then I will have filled the other card up all of the way risking not having a card in the hyperdeck that is empty and ready to go.

In regards to the SSD slowing down I have found this article where people seem to think it does slow down. http://forum.notebookreview.com/solid-s ... -down.html

OK... so that really does seem like an issue with the particular drive then. I have two 512GB Crucial M4s and they work perfectly.

Thats exactly what I have haha

Different firmware maybe (on the drives)?

That's exactly what the HyperDeck does, except it cannot continue recording to the same file, obviously, since it is on the disk that was pulled. But I've tested this, and there was not one single frame dropped when I pulled the recording disk.

Holding the record button works! Thanks a ton!

And... I'd still be very concerned about those drives dropping frames.. at any point. Very odd that we have the same drives too.

What are you recording? I'm at 1080i 60fps. That requires pretty speedy disk's.

720p5994 in prores. 220Mbps right? Well within the spec of the drives and much lower than uncompressed.

Just jumping in to say we've never had dropped frames when one of the SSD fills up. We do full sports broadcasts that occasionally fill up our 256GB and 512GB Crucial M4 drives. Even between multiple drives, the files all import well into Avid with no dropped frames.

We're recording Avid DNxHD 220.

Well we have...!
viewtopic.php?f=4&t=1397

But BlackMagic doesn't know anything...
... the only answer we get: "sorry, we have no idea..!"

Well I guess it's a fast-programmer-bug in the firmware.
"We have to launch the HyperDeck fast. If it recordes it's okay,
why border to program some extra tests so our costumers are
sure they would not losse any material..."

Our HyperDeck is now some toy we use when we don't have to trust it.
We have two 4-channels LSM's of EVS... They are expensive, but those we can trust!

Hi we have Both the hyperdeck Shuttle and Hyperdeck Studio in Constant Use every day
we use the OCZ Vertex 3 240gb drive out of almost 30 SSDs only ever had a problem with one of them
and that was only after being dropped!

we have found the Hyperdecks working perfect, never droped any frames...how ever we do record in the Highest resolution possible, dont know if that would make a difference ?


Mark

how ever we do record in the Highest resolution possible, dont know if that would make a difference ?

Hi Mark,

we really don't have a clue what the problem is...
(the problems where indeed only with SD 16:9 recordings)

But the most annoying part is: neither does BMD !

So how is it possible to trust BMD equipment when every time
something goes/is wrong, the only answer you get:
"wait for the next firmware update! maybe that will be your solution,
BUT we don't have a roadmap or a bug-tracking system. So we can't
promise anything..."

could it be the unit ? or the firmware ?

we also only ever record in SD 16:9 via the SDI with Embedded audio, all our work is conference based, so 16:9 SD is fine for what we do

also we have never updated our unit, since it was purchased about a year ago, so it only records in Highest resolution possible

i get about 1hour 50 per 240gb SSD and it has always seamlessly gone between the drives

(for a backup i also record a low ress DV file to a old datavideo recorder, same 1hour 50 only takes up 30gb )

good luck, let me know if you find out the problem
