5k video compresor?

[cristian]

Hi and thanks in advance!
In need to encode video in very high resolution for a video wall proyect (5816x2256 pixels). I had tried many choices, but the few that gave me the size...did't play in real time
Does anyone know of a good video compresor that can do 5816x2256 and play in real time? It could be .mp4 or mpeg2 format.
The software could be also mac or pc.

Thaks!!

I doubt if any prosumer encoder could encode at that resolution. You would need a very high bitrate and very fast drives etc.

But surely a 'video wall' cuts up the large video into smaller parts to give the impression of a large canvas. You do not start with a large canvas. ??????

Thanks for the fast reply.

Indeed I deliver to the client in that big resolution (5816x2256).

But why 5K ?. Even 4K is rather difficult to achieve.

standard levels/profiles of mpeg-4 have a max size of 4k and mpeg-2 is only 2k.

i think you'll find 5k is going to be image sequence only.

And even 5K cameras do not shoot video at 5k resolution (unless you are Peter Jackson)

new red cams do shoot 5k. they record to compressed image sequences at 2GB/min.

Sure. But that is about 12fps and $35k for the privilege.

you are off by a factor of 10. the red epic can shoot full 5k raw at 120fps. currently about $19k

You can add up to 6 red rocket accelerator cards into your system as long as you have the slots for it.

Many codecs will encode and decode 5816x2256. ffdshow's MJPEG codec does. So do x264 and Xvid (and probably Divx). I don't know if you'll get smooth playback though. SMPlayer (under Windows 7) was able to play a 5816x2256 30 fps Xvid AVI smoothly, but not the other two codecs. That was on my i5 2500K with a single 1920x1080 display. Other players I tried didn't play any of them smoothly.

I will try ffdshow codec to see if it will work for my video, thanks

isn't the 5816x2256p30 being downscaled by SMPlayer to 1080p? technically you can't say it was able to play it as it wasn't showing a full 5k image, now if you had a monitor that was capable of displaying such a resolution and it was able to play on your pc that would be a different story.

i have 4k content that i can view on my pc but since my monitor maxes out at 1280x1024 i really don't know how smoothly the content would play in full 4k.

Of course. That's why I pointed it out. In any case, the CPU had to decompress the full 5816x2256 video before it could downscale.
