#390980 GH5S Rumours...

Posted by Davide DB on 08 January 2018 - 06:40 AM




I'm finding my uw footage much much better with the use of IBIS.



Of course but it's something you can overcome with good technic and good balance as everybody else.

On the contrary, on land IBIS permits shots simply not achievable without a gimbal.


FInally more is better :)

#390935 Editing- Music First??

Posted by Davide DB on 07 January 2018 - 02:11 AM

- first select the usable clips
- second you choose a music background
- Third you edit your clips trying to assemble a story or just a simple sequence that makes sense.

For a video with just a music background seems obvious to cut on the beat but actually it's not so simple. It depends.
Just have a look on this useful thread:

This definitely gives me some closure about my ranting  :notworthy:


Legendary Sir David Attenborough, stunning images, Hans Zimmer and Radiohead soundtrack. What else?


#387963 4K to 1080 Pros & How To

Posted by Davide DB on 27 September 2017 - 06:16 AM

I'm starting to experiment with a GH4.


Right now I'm just interested in a 1080p output but a lot of doubts and questions arises...


On several articles and posts on the net I read that converting from 4K to 1080 results in a far "better" image and colors. IIRC I even read that I could get a 1080 4:2:2 clips from a 4K 4:2:0 clips. Mumble Mumble...

Could you elaborate on this and share your current workflow?


  • If I'm not interested in crop i could create a 1080p project and throw 4K clips at it.
  • I could create a 4K project, eventually take advantage of some crop and finally export everything at 1080p.


I made some test with the two above scenarios and frankly I couldn't find substantial differences between the two. I use Edius so I have no transcoding. I just edit directly the original 4K clips as usual. Of course the 4K project is slower than the 1080p one.


Thank you in advance

Hi guys,


Which type of SD cards are you using for 4K?


Thank you in advance

#387378 SATURATION - Colorful Marine Creatures from Indonesia & The Philippines

Posted by Davide DB on 07 September 2017 - 03:56 AM

I think Nick's film demonstrates why we need 4K even exporting at 1080p. The Ken Burns effect/zoom add a nice dynamic motion on steady macro shots.

This seems to be targeting the action sports market to showcase rad moves in excruciating detail with super slomo, bullet-time and time-slice effects.




Speaking of bullet-time effect, a small thread hijack... a couple of videos from Laurent Ballesta latest expedition.


It was made with a tons of gopro cameras mounted on a DIY semi circular pod.

Here a brief description of the custom build:





And here at 2:44 a small preview of the upcoming results:

As discussed dozen of times continuos AF underwater is really like a Unicorn. Everybody talk about it but nobody saw it. Maybe DPAF will change things but a video camera with a decent sensor size and a reliable AF simply does not exist.
Actually for WA shots I don't see the problem in 99% of use cases:

#1 stay hyperfocal.
#2 use AFL button
#3 use center point focus and avoid multipoint focus

I never missed a shot except when I crashed my dome on a coral getting a huge scratch on it.

Hummm 24mm it's really too narrow. With a flat port it's even narrow. I see it as a very specific tool.

It a shame that Sony chose that infamous shape for its real action cam fdr x3000.
I had the opportunity to use it and it's the best one. Optical stabilization and amazing image quality.
Unfortunately no uw housing and no way to have a display in a useful way.

No surprise about Nat Geo: http://gizmodo.com/n...nier-1729683793


No competition for greed + stupidity...


Very bad news. R.I.P. NGC


What we are witnessing is a boost to the concentration and verticalization of media companies. Murdock is the owner of Sky, the largest European satellite broadcaster. He was already distributing NGC, History and Discovery channels in Europe. Now he bought NGC so another piece of the puzzle is set.


I guess we have two phenomenons at the same time.


As Peter pointed out we are moving towards mediocrity and unless viewing figures fall down it's an unstoppable process. If you think about it it's simple to explain. I'm fifty and I grew up with BBC documentaries enjoyed in a completely different manner: Sir Attenborough commenting on Japanese macaque for one square hour :) but he was aired once a week! Nowadays a cable/satellite channel broadcasts 24hx7. No way to fill such time interval with quality contents. So they are forced to buy and produce a lot of low budget documentaries shows to fill their TV schedule. In the resulting hodge-podge, quality content has less appeal and probably less revenues.


At the same time, the old "documentary" category has gone trough an "hybridisation process" with other genres like reality shows, talents, mockumentaries... The result is in front of us. The same applies to other formats as well but while we stay within fiction, results are not so devastating.
