[GRP PROJECT] Edit

Once we had the footage it was time to import and process.

The software used for such a feet was the Autopano Video Pro by Kolor.

I believe Kolor is a subsidiary of GoPro, which would make sense as the hardware and software go hand in hand together.

There is a fully licensed copy of said software in the University building.

One copy.

And the room it was installed in had been fully booked up for some time leaving us with no option but to use the free version obtainable from their website.

The free version can do all the things the full version can do, but limits your output video to 30 seconds and applies a couple of watermarks.

No bother. The software (if you have your files organised) will automatically pick up the metadata on the SD cards and stitch the footage together to create a flat image which can then be stitched into the shape of a ball.

It is very difficult to speak extensively about the edit due to the automatic nature of the software, but it is worth mentioning that due to the 30 second video limit, we had to set up a batch render which then worked overnight to process the entire video in chunks.

We then combined the clips in NLE software (Premiere Pro)

At the overlap points between the images there is a certain delay which is hard to explain physically, but it is due to the safe zones of each image being out of alignment.

Any attempt to rectify the overlap issues would result in more issues, so we just had to be thankful the footage has come out as clean as it has, regardless of perfection.

All of us knew perfection was a long way away when it comes to this nature of filming.

The audio and video were split, and although the omni had captured a fairly clean sound, the focus of the product is the music, so we had to treat that with the most care, taking it away and producing a clean audio file which could be reapplied to the video.

Finally we replace the live audio and we have an even cleaner product.

On top of this, there is a lot of background audio produced by me (phil) and Greg as we act out our bits in the video. By removing the live audio we have greater control over how the audio sounds. This is our main focus after 360°.

Video quality wasn’t excellent, and it’s something which needs improving before next 360 project. Even after a 1080p export we found there was a distinct drop in resolution. I read on a website that preserving the 4k output from the cameras is the best solution as I believe even if we did output 4k we would have continually lost quality as the different angles were compiled into video.

[GRP PROJECT] PRE-PRODUCTION / FILMING

[360 Video] 1. Pre-production / Filming

At the previous post, we said we will film 360 degree live music video.

[Example of 360 degree music video by Go Pro Omni]

 

To film 360 video, we need 360 degree camera. In the past, 360 degree filming is expensive job but nowadays many camera manufacturers are releasing 360 degree camera.

 

There are several product like these.

Which can connect to mobile phone and film the 360 degree video or stream 360 video on the Internet.

[Go Pro Omni; Photo from GoPro Website]

6 Go Pro array to film 360 degree film using Go Pro. Well known for professional way to film 360 degree film.

 

For our 360-degree film, we plan to use Go Pro Omni. Because we can hire from the university equipment rental store and most professional solution we’ve got. Go Pro Omni is basically a hardware to 6 Go Pro Hero4 Black to film 360-degree film. The Omni connects 6 cameras like a single camera and it makes film maker doesn’t need to sync up all footages. Moreover, It can film up to 8K video. After filming, we can edit the footage with dedicated software called ‘Autopano’ but also we can use general video editors such as Adobe Premiere since they also have 360 degree video editing feature.

 

As I said in the previous blog post, we will shoot 360-degree video about live music so we need performer. In the initial plan, we plan to film a professional band on Manchester Academy introduced by our group member Phil but they changed the schedule because of the production reasons and we cannot film the band.

Instead, we filmed the performance of Chris Walker, who is our group member and music creator as well.

Before filming we’ve checked how to film using Go Pro Omni and we’ve found out several interesting aspects.

  • Must use 4:3 ratio not 16:9
    • (Interesting!)
    • Since all professional videos are in 16:9, in 360 degree video filming, we must use 4:3 ratio to avoid crops.
  • 1440p should be used to film 4k
    • There are several options in Go Pro but to film in 4k, 1440p must be used.
  • All cameras must use same frame rate
    • It’s because not to suffer sync problem
  • Should tune exposures before filming
    • if one camera filming sun and another camera filming ground, it should be manually adjusted to avoid re-shoot
  • Even though we use remote from Go Pro, the video is out of sync and should be manually synced up.

For filming, we installed the Go Pro Omni on the microphone stand in the centre of the room. The room is low-light but Go Pro handle this well.

Here are some pictures of the filming.

During the filming, we found out several problems.

First, the power problem.

It is hard to source 6 Go Pro powers (which have short battery time) seamlessly during the shoot.

Second, sync problem!

Even though the Go Pro manufacturer said Omni can sync up video without any problem, it didn’t. On the day we found the Go Pro didn’t start at the same time and it means that there will be an issue regarding the sync of 6 Go Pros when stitched into one. We thought this would inevitably extend the edit period as we would need to sync them. However upon review we noticed all footage was syncronised. When we consulted the manual we learnt all the other 5 GoPros are slaved to the actions of camera 1 in the omni. After all we could confirm the frame does carry data signals, even if the power supply was faulty.

After shooting video we’ve found out that 360-degree video is not only interesting to watch for mobile devices with gyro sensor but also can be linked to VR, Virtual Reality.

If we film in 360 degree, we can use it as a VR contents. For example, VR concert footage can deliver viewers more lively footage from the concert. To do so, I personally found out it would be great if surround sound applied to the 360 degree video. Although it is worth mentioning that for VR users there is a minimum 50fps due to the nauseating effect of a lower frame rate. That’s just science and psycho-optics.

 

To sum up, these are the pre-production and filming process we’ve done. In the next post, we will talk about post-production (editing) and final feedback of our contents.

[GRP PROJECT] Research

On the Internet, there are many videos about many things.

For example, this is the very first video on one of the most famous online video platform, YouTube.

“Me at the Zoo”

It’s short video clip man standing zoo and talking. It is from one of the YouTube’s engineer to test the YouTube platform.

Since online video platforms like YouTube, Vimeo start to emerge, people start to share their stories and creative ideas through video. Moreover, viewers start to watch those videos and talk about them.

In 2017, there are a lot of videos became famous and many video creators creating video as their primary job.

There are several famous ‘YouTubers’ who’s posting videos regularly. The genre of the videos are vary from gaming to tech to daily vlog.

[A video from famous mobile game YouTube ‘nickatnyte’]

[A video from influential vlog YouTuber ‘CaseyNeistat’]

Besides the daily-weekly basis videos, there are another set of contents called ‘viral’ which means hot contents in certain time.

Both videos look like meaningless in terms of music quality but there are more than 3 million views on each videos and almost every young adults at that time know about the contents.

We call this as a viral video. Nowadays, viral contents are becoming famous in Facebook, Twitter, Instagram as well since these SNS platforms start to do video services.

These are the general ideas about online video platform and creators. and let’s move on to assignment itself.

In the group assignment brief, we have two options.

  1. Short video
  2. Interactive video

We want to do short video but we want to have some interactive aspect as well. We discussed about the topic and find out we can do 360 video.

Since we are all interested in music, we want to do music related video.

So after we discussed, our initial plan is

  1. Concert video
  2. 360 degree Video

Since 360 concert / music related videos are becoming popular, we want to create one of them.

These are the examples we have found about 360 degree music related video.

[Example of 360 concert film; created by band itself]

[Example of 360 concert film; user/audience created]

These films are good for events such as concert because

  1. Viewers can engage with / closer to the video itself, because they can choose what they want to watch unlike the general video. (If viewer likes bass player, he or she can track the bass player in the 360 video)
  2. VR (I will talk about this later)

Back to our video, our script is basically this.

  • Band perform a song
  • Record the performance in 360 degree camera

Our storyboard / shot configuration came from this music video.

It looks like a good idea to us because since band playing in one single room around the 360 degree camera, viewer can clearly choose what they want to watch. Besides, they can watch whole band playing when there’s a wide shot.

In conclusion, we decided to do

  1. 360 degree music live video.
  2. Performers are around the camera in 360 degree.

In the next blog post, we will handle about the production itself and how it is created. (what gear we use and how)

Also, VR content as well.

Prep for band gig @ Academy 2

Screen Shot 2017-04-24 at 12.12.20 PM

I would like to show you how me to prepare for live sound event as a sound engineer especially, FOH Engineer.

  1. Technical Rider
    1. Input List
    2. Output List
    3. Sound Requirements
  2. Console Show File

First of all, for technical rider, I put FOH and Monitor requirements.

For this event, I knew the venue spec so I didn’t put any specific console, PA specs.

WE NEED

Stereo PA system with subwoofers

4 individual monitor wedges and drum fill

Vocal, Instrument Microphones and DIs (including 4 wireless microphone)

Cables (Besides the backline, instrument related cables)

Microphone stands and quantity

Next, I put stage plot.

It varies from the event to event.

BUT, One tip I can give you is DO NOT USE BAND MEMBER’S NAME. Sound Engineers don’t know band members’ name unless they are hired by band. Still, it is safer to put instrument / role name than band members’ name.

Lastly, In / Out list and if necessary, monitor requirements.

For this event, I use 25 inputs and 10 outputs.

Screen Shot 2017-04-24 at 12.20.51 PM

I usually carry all microphones but for this event, I hired all microphones and DIs so my choices are limited.

The technical rider varies from band to band, event to event so there’s no wrong way or right way but those things are can be put in the general technical rider.
