I'm getting dropped frames, "REC" light blinking. I'm using a SanDisc Extreme Pro 95 MB/s . Footage unusable. What can be causing this? Pls help. Thx, Johnny

We need to know a bit more. Which format do you try to record? There is a list in the manual which cards will support which format.

Plus, there's a difference between 95 MB/s cards with a "1" written inside of an upper case "U" shape or a "3" there. Which one do you have?

Why is the thread titled "Audio In... ?" How is audio relevant?

Good question Rick, I wounder too...
Cheers

I had a mix up with using my real name I actually still need audio question answered. I need to recheck what r the exact specs on the card on my dropped frames question .

Thank u for ur indulgence.

You can out the card in the BM Speed Disk utility (available from BM Support page) to see what the card you have is actuall doing (write Speed).

So, what Is your audio question?

I want to send my audio from my recorder into the audio of the PCC. I tried it but I just got static. Is there a procedure for line/mic(?) input? Thx

OK, John what is PCC, a Pocket camera or Production camera? If one of these, yes in the camera Audio menu, you can assign the mic/line input jack to either mic or line level. The mixer is a line level output, so I would select line input on the camera. Now, the Pocket camera is unbalanced audio in, themPordictiin camera is balanced audio in, each expecting a different audio level input. What is your mixer/recorder balanced (XLR or TRS) or unbalanced (RCA or a Mini jack useually, like a stereo tape line output).

I will assume you mean the Pocket Cinema Camera, so line in is unbalanced stereo plug. You can take the unbalanced line out from your recorder Mini TRS jack, set the camera to line in, level at 50-75 and control the audio level from the recorder to get a good feed signal.
Cheers

It's a 3 inside the U.

That's a good card (if not faked) and a good start telling us some details.
Now, which camera and recording format?

Pocket cinema camera

Pro Res 422

ProRes 422 is really light. I'd suppose a faked and/or defective card then.
I can record RAW on such cards in my Pocket without difficulties.
BTW, was the price of that card 'surprisingly' cheap?

Will BM Speed Test work on Windows? (Also, couldn't find on BM site.) thx

I had a previous card that was same card except in micro-size. It too had the same problem. So I thought maybe it was the micro card type that couldn't handle the stream. Then the problem persisted on the full sized card.

The card runs fine capturing RAW(!) But not ProRes. Go figure. Might I need a firmware update. Could that possibly help? Thx...

Firmware on the card might be the problem. Quite awhile ago there were reports of higher quality ProRes codecs running fine (higher bandwidths) and lower quality failing, so these things sometimes seem to defy logic.

My Wise CFast 2.0 cards handle all raw on a single card up to 30 fps, but now with camera firmware 4.3.x the cards fail doing 60 fps with Dual Card recording. Not logical as the bandwidth to each card is the same as single card 30 fps, but a firmware update of my card is going to fix this anomaly soon.
