Shooting in Raw on usra mini 4.6k ef. Video file not there.

Hello all,

This my first post.

If my question has already answered else where I am sorry I have not found it.

Just picked up a usra mini 4.6k ef.

This is my first pro camera.

Shooting in Raw 4k I only get a audio file and no video file on the fast card.

It will play the video on the camera but when I put the card in my reader I see no video file just audio and pic files from the recording.

I do not understand what is going on?

I see video files on pro res.

Latest firmware 4.9 is on it.

At least it says it is the latest.

Can some one help me please and thank you?

Still learning how to use this camera.

Shawn.

Proper procedure includes:
1) only using CFast2 cards that are on the BMD recommended list; suitability based on claimed speeds on the card has little to do with working in the camera; best to buy a card that will use the resolution and maximum frame rate you want to use

2) formatting the CFast2 card in the camera, if you are editing on a Windows computer, you can select exFAT; if on a Mac, it can read exFAT but best you format to OS X Journaled

3) in one of the camera Menu / Recording pages, there will be an option to Stop Recording if there are Dropped Frames.

Did you follow these points before recording?

Take time to read the operator’s manual for the camera if you have not done that already.

Shawn, I think what’s going on is that you’ve recorded cDNG and are trying to play those files in the file browser of your computer operating system. cDNG is encoded as an image sequence, so when you look at it in a simple file browser you will see one audio file per clip plus a ton of stills.

Load your media into Resolve and you will see those cDNG files as video.

Ok guys.

Thank you for your help.
I was not importing the files right.
I to the media pool and it showed me the raw video file.
When i was going to the import and it let me choose files the other way it showed select files.
That was wrong.

There a link to the far left on the media pool at the bottom of Davinci Resolve.

Yes I was not loading the raw file correctly.
I have since learned how.
Thank you,

I found it under this title on YouTube.

Hello all,

This my first post… when I put the card in my reader I see no video file just audio and pic files from the recording…
Shawn.

Sorry, Shawn; I completely misinterpreted the meaning of “pic files” which to me meant single frames due to a recording error.

Rick your good.

I have learned how to setup my settings on my camera from some of your other posting.

Thank you to all of you that are here to help.

I am a newb at this.
I have been using a iphone 15 promax from my videos and I am not stepping up to this camera.

Looking forward to seeing how that is going for you. Lots of variables are now in your control. Everyone has a different view on what they are trying to achieve. Enjoy the forum resources whenever you have any questions.

Are you also going to rely on DaVinci Resolve for your edits and colour grading?

Does the Ursa Mini 4.6K shoot BRAW? I thought BRAW was limited to the Mini Pro G1 and G2. If it does, then I would be interested up upgrading the Ursa Mini 4.6K I patched up from wrecks to more closely play nice with Mini Pro footage from a patched up Mini Pro camera.

Robert, I believe the reference to raw on the URSA Mini 4.6K camera implies shooting uncompressed CinemaDNG which is what I shoot every time using that camera (along with BRAW Q0/Q1 on the BMPCC4K).

Uncompressed? I'm a hoarder when it comes to what we shoot (stored on LTO tapes) and even I am not crazy enough to shoot Uncompressed. 3:1 FTW.

As an aside, what do you use for your archives?

LTO-6

And as for codec, depends on the importance. Original 3:1 / BRAW Q0 for the important stuff and DNxHR HQX 12bit or ProRes422HQ for the non important stuff. Which I usually transcode from 3:1 or BRAW and whatever other codecs I get. Arriraw, RED etc.

When I have time I also trim the RAW files.

Looking to get into LTO-9 though. Its so worth it. But its very expensive.

Thanks for the feedback. I’ve been using ProRes 444 which of course takes a lot of storage. LTO is appealing once you buy into a system. One thing that gives me pause is long-term access to the tapes. Is one able to read an LTO-6 generation tape ten or fifteen years later on a hypothetical LTO-15 system? Sure the physical tape is good for several decades, but will the LTO systems be able to use all previous generations of tapes?

Unfortunately no.

They're good for about 3 gens backwards.

So LTO-6 can

- read write LTO6
- read write LTO5
- read LTO4

The good thing about this is that second hand units can be found pretty commonly. So if my unit breaks in a number of years I'll probably still find a cheap unit to transfer the tapes to a new LTO system or whatever new invention.

If you still have that interface it uses or can find an adapter in the distant future …
Anybody tried SCSI recently on a modern machine?

Yes.

The LTO tape drive is connected to the computer via SAS (serial attached SCSI) HBA card (PCIe interface) and fiber optic cable. You can find these everywhere they deal with enterprise stuff and servers.

SAS will probably outlive SATA by a large margin since its extremely common in enterprise.

Funny how one generation’s premier interface, becomes obsolete so quickly. I’m relying on large USB drives for my archives and hopefully the disk format will survive (not that I have anything worth preserving but after that DJ in Alberta unearthed Joni Mitchell’s 30 year old first tape recordings, you never know, one of my music videos might be of value.

SCSI instruction set is alive and well in modern SAS.

Thanks, good to know. We still have a drive sitting in the attic, you never know when you may need it.
I can still remember fighting with SCSI chains and fiddling with terminations

Good luck getting that to work. Thought you meant modern SCSI which is SAS now. Uses the same instruction sets but obviously its not parallel anymore.

That was my point, I should have mentioned in my remark that I was referring to parallel SCSI.

Firewire comes to mind.

But still, you need to have a cutoff time for these before it gets ridiculous. Every 15 years or so you should switch to new storage to keep up with the modern interfaces. I think 15 is reasonable. Even on HDDs its advisable to refresh the data by rewriting them from time to time to avoid degradation.

I still have data stored on Firewire and a few different cables, that I can hook up to an old iMac with flaky graphics. One day I won’t be able to boot the iMac and then that’s lost.

One more word to the wise: keep your old machines on the latest software they can run to have any chance of prolonging their usefulness. I wanted to use an old iMac as a secondary window on the Mac Pro 2019, but I was unable to update it from it’s old macOS Lion to a more recent version that was supported as a secondary screen or mirror on the Mac Pro so now it just runs my old iTunes music and a Firewire drive.

I am thinking about M-Discs .. One Hundred Gigabytes are easy to find and not too expensive ..
They are given for a duration of One Thousand Two Hundred , and Fifty Years ...

I am going to put those discs in a solid box and bury the box in the inner yard of an Old Monastery in Center France .. and , on a Rock , i'll engrave and explain our Story , what is an M-Disc and what is an M-Disc Reader ... with schematics ..
Of course , I have some films ( also old family 8 mm films from the fifties ) and still Pictures Dear to my Heart , it's like a Bottle thrown to the Sea .. but , maybe , in One Thousand Two Hundred , and Fifty Years , someone will find our story ..

Among those still pictures , " Sully " .. our beloved American Cocker .. he is training for going back to the Moon ..

Definitely, and more often than every 15 years. One should spin them up every 3 months and copy every 3, maximum 5 years.

Hello .. For Archiving , do not forget a useful Tool : CHECKSUMS .. On Linux , with the " MD5SUM " Command Line , it's easy to create a File's Checksum , and easy to Check the Valid Perfection of a file ..

The Checksum is the Footprint , the " DNA " of your file ..

You then take note and write down the specified checksum in relation with the file , and you can check Any Time the Health of your file .. Your computer works for you , you can go drink a Tea or a Coffee ... Anyway , it could " take a while " depending on the size of the file ..

Good for Hard Drives , Usb Storage , Memory Cards , but on LTO Tapes .. well I do not know .. it might be the hell of a process ..

Some software , I think of the Linux " K3B " Disc Writing Software , directly show you the Checksum of the file before engraving it on the Disk ..

For the Fun :

" Sur l'écran noir de mes nuits blanches " ..... " On the black Screen of my sleepless Nights " ...

Have a nice Week-end , enjoy life , and Take Care ...

Mike ..

LTO has an automatic built in checksum.

Linear Tape Open has an automatic built-in Checksum ...

OK, Thank you very much for this information ..

For very large Documents , it's a Solution , but I do not trust Tapes that much .. If only the Industry could develop large Diameter and large Capacity M-Discs ..

Thanks Andrew , have a Nice Day ..

Mike ..
