1080x48p Editing GoPro Hero 3+

[3dguy]

Curious, as I haven't edited 48p before.
I am using the new Hero 3+ to shoot 3D.
Since Edius doesn't have 48fps listed, what rate should I use?

Just manually setup a project that matches the frame size and resolution that you have shot in. This is what I do, but in 2d, so I am assuming that it is the same for 3d. Although I don't use 48, I would imagine it wouldn't be a problem with E7, as it is one of the recognised higher frame rates, being double the film standard of 24.

BTW. You may want to be careful shooting 1080 on the GP. It is not the best way to resolve detail from the sensor, due to the way the the GP processes down from the full sensor. I wouldn't usually recommend shooting above the resolution of your output, unless for reframing and creative editing etc. But you may want to consider shooting 2.7 with the GP, and just use it in a 1080 project. I use E7 and set the resize for progressive best for motion (I think). And the GP 2.7 footage looks really cool in a 1080 project, with loads of detail.

Stated, actual and resolved resolutions can be quite different for any shooting resolution, especially for cheaper cameras.

Sorry to butt in here but may I ask, so for best results with the 3+ its best to shoot 2.7K, would this work OK in a 50i timeline?

Thank you.

Tony. Importing progressive 2.7k GP footage into an Edius 1080 interlaced timeline, will be fine. Just remember though, that progressive will always look best played back progressive.

OK, thanks Bob.

Yes, that is what I have come up with but think about "Prodad Respeedr" which allows the 25p to be up-framed to 50p and that gets rid of all the jitter
Quality is superb, have tested using the Blend Difference filter, nothing there

I tried 4K from the GP at 12.5 frames up-framed to 50 but has some movement jumps near the edge if objects are too close and fast, but if there is no real close up I cannot pick the difference with 2.7K at the moment
OK it means processing the video before bringing into Edius but well worth it
Only outputs mp4 or mov at the moment and does not read HQ codecs
A trial is available on the Prodad site, bit rates of output can be set (Not inteligently} but by nominal settings vary from 13mbs to 70mbs

Thanks Barry for the advice.

48p footage in Edius 6

Someone has asked me to edit something that they shot on a GoPro from a drone, filmed at 1080p 48fps.

I don't have the footage yet but just checked and Edius doesn't have presets for 48p

I will probably use a 50p preset but would like to know if anyone has dealt with this situation and what gave the best results. Thank you.

(I asked: "Why did you select 48p?" he said it was the fastest frame rate available at 1080p.)

[antonsvideo]

use 50p preset and add the 48p clip to bin

in the bin, change the frame rate of the 48p clip to 50p prior to adding to timeline and the result will be perfect

If you change the frame rate you will also change the speed, which will be especially noticeable if using audio from the source.

48 to 50 is the same 4% as 24 to 25, so in most cases not a big problem.

You have 2 choices- half fps to 24p (edit tin 24p project with Nearest Neighbourhood setting in Speed settings) or do what Anton suggested. Anything else=fps conversion, which will be crap in Edius.

Yes, and very noticable to someone familiar with the original footage, and a lot more noticable if using un-corrected audio from the source.

2.7K 29.97p Protune mode, color flat, WB raw. I'm doing a 3D underwater shoot this week with two 3D GP Duals and one other 3D camcorder. That setting is the greatest thing since sliced bread on the GP. Definitely the sweet spot☺ Fortunately, my needs don't require 24p.

[Liverpool TV]

Each to their own. I much prefer the source versions of stuff. For instance, I'd always get the American versions of their shows. And for stuff that I'm involved with, I'd always edit at the source properties and not change any speeds wherever possible.

Going back to the original question. Does this mean that Edius doesn't do 48FPS? I don't think I've ever had to find out. Although, it does seem strange that it wouldn't as it does 24 and double frame rate of 25 and 29.97. Or does it only do 48 at certain resolutions?

[Liverpool TV]

No way to create 48p project. Not many apps have it as it's a "fancy" fps.

That's quite a surprise with Edius' flexibility. Maybe something that GV could consider for a future upgrade?

48fps is not unusual, at least The Hobbit was shot with this frame rate
