Question about 4K video from GoPro and Vegas Rendering
on May 12, 2014 at 8:29:49 pm

I've been using GoPro2 to film a lot of my son's team hockey games, and using Vegas to edit and render so I can post them. Lot's of videos are at http://tiny.cc/gvcvideos if you need to see examples of my questions below All these were shot in 1080p.

Questions:

1) If I upgraded to the GoPro3 Black which shoots in 4K, would I have to render it down to 1080p for universal use (youtube, DVDs, etc.) and would the closeups therefor be less grainy that the ones in the videos?

2) I'm currently using an I5 to edit, which is bad enough with 1080p, would it even be able to play the 4K video?

3) I don't want to purchase the GoPro3 Black if it's not going to accomplish what I want, the clearer closeup of goals and hits.

I guess that's all my questions for now. Just don't know much about this area of editing.

[Roger Smith] "1) If I upgraded to the GoPro3 Black which shoots in 4K, would I have to render it down to 1080p for universal use (youtube, DVDs, etc.) and would the closeups therefor be less grainy that the ones in the videos?"
Mostly yes. YouTube does accept 4K but only people with really high bandwidth internet connections will be able to play it. It's best to deliver 1080p for a broader audience. DVD will only be 655x480 so 4K is kind of a waste for DVD delivery.
[Roger Smith] "2) I'm currently using an I5 to edit, which is bad enough with 1080p, would it even be able to play the 4K video?"
No way! I guess you haven't read the tech specs for 4K on Sony's web site. Sony recommends a minimum of an 8-core computer, 16GB of memory and RAID 0 hard drives. A Core i5 doesn't even come remotely close. You're looking at Dual Core i7 Quads or a single Core i7 8-core minimum. A 12-core or Dual 6-cores is probably a smoother editing experience.

I assume you were zooming in after the recording in Vegas? Shooting 4K would accomplish your goal of having more image quality to zoom, but it sounds like you don't have a PC that handle 4K.

Thanks for the info. I had already decided to upgrade computers, but just found out the 2.7k and 4k only shoot in ultra wide. That kind of sucks how I use it. Also read that 2.7k is much more stable, and 4k locks the Gopro up frequently.

You're welcome. 4K is brand new so you goat expect some growing pains. The good new is it still shoots 1080 so it's a good purchase for someone like me who doesn't have a GoPro yet. I've had my eye on it.

I shot those hockey videos with 1080/30 without protune, and they came out ok. I just want better closeups.

One thing I'm wondering if anyone knows is if the ultra wide lens just stretches the sides like 4:3 showing on 16:9, or it stretch the whole picture equally. I could probably cut the sides off if it did the former.

Anyone know?
