Raw Video / Interpolation to upsize RAW video?
« on: June 12, 2013, 07:14:04 PM »
Just curious if anyone has messed around with this and gotten good results? I am specifically talking about using a photoshop plugin like Alien Skin Blow Up in a batch process and then output to a 4k cinemadng format. I have tested on a short clip but I have no way of viewing at full resolution- but the blown up comparisons look better.  Anyone else working on something like this? - It does take up a huge amount of room and processing power :-) I am interested in this specifically for 4k final output to DCP for a future project.

Few thoughts about RAW video:

1. Is it possible to use USB instead of SD card? Theoretically it is 60MB/s. Practically? And would PC or/and USB stick work?
2. One crazy thought: What about combining USB and SD card. For example odd frames would be stored on SD card and even through USB on USB stick or computer. And it would be combined in post-production similarly like HDR video.
3. Is it possible to shoot in RAW but only capture luminosity? Black & white picture would require lower bit rate.
4. Instead of using RAW would jpeg work better?

Thanks for your work. I am thankful user of pre-alpha 2.

Re: #4, what about implementing sRaw or mRaw for Raw video?

UHS-I can either support a clock of 100MHz writing 4-bits (1/2 byte) per clock = 50 MB/s or UHS104 specifies a 208MHz clock writing 4-bits per clock = 104 MB/s.  The SD controller in the T4i is a Macronix MX25L6436EM2I-10G with a clock speed of 104MHz.  The T4i will not support anything faster than 50MB/s. Slice and dice your video however you want.  That is the (theoretical maximum) hose you have to work with.

Sorry to be daft- but just trying to understand this limitation- how does this apply to CBR override for instance on the T3i? CBR 1.4 for instance has been shown to be around 62mb/s?

Sorry, just looked in to this more, it is- bits vs bytes...CBR not using nearly as much throughput as RAW
