Buy raw video hard disk

[F u r u y á]

Hi,

Does anyone know where I can buy hard disks or DVD/Blue-Ray with raw 1080p/60Hz (or higher) video?



Thanks in advance

What should that be??

Blu-ray discs are commonly 1920x1080x24p, 23.976p (16:9), (NTSC), but there are other resolutions. You can look to the upper left on this page for 'WHAT IS' Blu-ray for more information.

And you would need to tell us a bit more, as I'm not sure what you are asking either.

You need one of these: http://www.red.com/

Sorry guys, I was talking about RGB/YUV movies (raw movies from camera acquisition). That's for testing purposes in development of set top boxes for the Brazilian Digital TV.

You are saying you have a 1920x1080p/60hz camera? What output connection? HDMI? SMPTE-292M?

Best to give the model numbers of the equipment you are testing.

No...

I was answering to [_chef_] and redwudz. I said that the kind of movies I want is RGB/YUV 1080p60 (or higher). I don't have such cameras.

I'm still not clear what you are asking. You want a "raw" hard disk that records 1080p 60fps? By raw do you mean uncompressed?

Something like this?

heheeheh


Yes, and what I want the uncompressed movie (not cameras, etc).


I don't care about the media (HD, BlueRay, DVD), I just want the movie hehe.

[jagabo]

Just take a 720p60 video and upscale it to 1080p60. Or take a 1080p30 video and change the frame rate to 60.

First reaction is why not create one?

Second reaction is why do this and what are you trying to do?

[F u r u y á]

We can't create one because we don't have such cameras. That's for testing purposes in development of set top boxes.

[jagabo]

You don't need a camera. Just upscale or tile a smaller video to make a 1920x1080p60 video. That will work as well as a "real" 1080p60 video. Your set top box won't know the difference.

I'm curious where the set top box is getting 1080p60 video? It's not being broadcast anywhere in the world. Very few HDTV sets accept 1080p60.

A good reason to make the lab wanna make those tests


jagabo, I will talk to them about your ideia.

If you are actually trying to make QUALITY comparisons, you need a very clean, uncompressed, master source. In which case, you probably DO want a pro camera so you can create your own, if you don't know anybody who has access to one.

BTW, hardly anybody here in their right mind is going to try and upload any length of uncompressed HiDef beyond a few frames or seconds. Too Big.

If you are ACTUALLY trying to make a new STB from scratch that can work with 1080p raw files, you ought to already be a member of engineering organizations like the NAB, IEEE, SMPTE, etc. (whatever's appropriate in your country). And THEY would have connections to get the material you're seeking.

Of course, when I see answers like "he, he" and roundabout answers to straightforward questions, I'm thinking this may not be a legit thread...

Makes me want to say "Put your mother on the phone" or in this case "Invite your engineer into this forum".

1920x1080 uncompressed YUV 4:2:2 video at 60 frames per second is about 250 MB/s. Obviously, no single drive is going to handle it.

A simple AviSynth script like this will take a 1280x720 source and convert it to 1920x1080p60:

src=WhateverSource("1280x720.whatever")
StackVertical(StackHorizontal(src,src),StackHorizontal(src,src))
Crop(320,180,-320,-180) #or any combination leaving 1920x1080
AssumeFPS(59.94) #not needed if your source is 59.94

I really can't see when I was disrespectful to you guys. I won't take your time anymore.


(jagabo, thank you for your replies. Really huge data rate (never thought about it). Maybe SCSI hard drives can handle it but I'm not sure.)

We just want you to be more clear about what you are trying to do.

Uncompressed 1920x1080i/29.97fps maximizes a SMPTE-292M link (1.485Gb/s) and requires three to four conventional hard disk drives in RAID zero for 1x recording or playback.

Uncompressed 1920x1080p/59.94fps requires two links (~3Gb/s) and double the number of drives in RAID.

Thus a "disk" looks like this.


You are asking for something more extreme than you realize. That is why we want more info on the requirement.

SAS would be an good option.

Is this for "Sky brazil" ???
