How to create a video 10000*1080?
on May 10, 2012 at 10:40:46 pm

Hello my friends,

I have to create a video 10000*1080 pixels for a videomapping.

My boss needs 5 videos (2000*1080) for 5 screens to use a watch out system and show one large video (10000px).

Now, there is a way to export one composition (10000*1080) in 5 small contiguous videos (2000px)?
(just to know, I tried to render one 10000*1080 composition but video is black!)

Or there is another way to do this crazy project?

Please forgive me for awful english...

Thanks a lot.
Federico

To render out as 5 videos you could place your 10000x1080 composition into a 2000x1080 composition 5 different times and just re-position it in this new composition for each of the 5 sections. Effectively cropping 8000px wide off in each composition.

Awesome! I have to plan one of those for 2013.
You specs on projectors? Barcos?
What kind of players are you using?
We're shooting for RED RAY ;)

Uhm, now the first issue!

Have you any idea how to show a single video footage movement in all the 10000px line space?

P.e. I have a F1 racing car in pan (left to right) on a video 1920*1080.
Have you any idea to start the pan on pixel 0 and stop the video footage on pixel 10000 in my long one frame, without show the 1980*1080 frame edge?

Just an advice for me ;)

(I think I'll write you many time in these days ;)

Thank you!

Federico

It depends on the footage, you could scale up the entire image to 10,000px wide, but to not cut off your F1 car it would have to be fairly small in the frame as you would be cropping out a lot, And blowing 1920 up to 10,000 means the overall resolution will be pretty low, 4k or 5k footage would probably be a lot better but still be "blown up" to fit into the 10,000px wide space.


This is an alternate technique that is likely to only look right if you have the proper shot & time/patience to make it look right:

If it was a static level shot and the car enters the frame from the left and exits the right, you could manually roto mask the car out for the entire duration it appears on screen, and then use position keyframes to move it from the left to the right in your 10,000px composition. The wheels might look a bit odd as the car would be traveling 5 times the distance while the wheels are still spinning the same speed. Parenting an adjustment layer to the car layer that has circle masks with feathered edges around the wheels, with "CC force motion blur" effect applied may help to hide this. For the background you could use a portion of the same static shot that doesn't have the car in it yet & duplicate it 4-5 times, then stitch them together to create a 10,000px panorama for your extended background(cloning and/or feathered masks probably needed to do this seamlessly). For the background to look right the road would have to be completely level in the shot & nothing unique/identifiable that would look obvious when repeated 4-5 times. If you have some creative freedom it might look better and be easier to use a different image or design for the background all together.

[federico betta] "Do you think a macbook i7 2.2gh 8gb ram is ok to make a 3 or 5 minutes lenght of this type of video?"

Possible? Yes (with CS5 or higher).

Ok? Not for me. I do a lot of large raster work, and I find laptops pretty unusable for serious work at large sizes like this. I can work a lot faster on my monster workstations.

One tip for you -- I recommend rendering to image sequences. That way, if you have to make a small tweak, you only need to re-render the affected frames, not the entire piece.

Also, read everything in the Improve performance [link] page of the docs. I use proxies heavily, and I use Shift-RAM preview with frame skipping and ultra low resolution for quick previews all the time.

Good luck with the project -- sounds like a cool one.

Thank you for all the great tips!

I hope my boss supply me with a new machine!
