Just for any new readers, I am head of technology for BBC HD & 3D and this is an update on the next phase of the BBC 3D trial. We have now moved from sport, music and animation to drama!

Mr Stink is a TV adaptation of the book by David Walliams. I won't give anything away in the post for those who love the book and for those who have never heard of it - just watch!

In this post I want to give you an overview of some the technology and processes used during the making of Mr Stink with comments from a few of the people involved.

Mr Stink transmits in 2D on BBC One & BBC One HD on Sunday 23 December at 6.30 and is repeated on Boxing Day at 12.40. The 3D transmission is on BBC HD on Sunday 23 December at 6.30 and shortly after on BBC iPlayer for seven days

Mr Stink is the first programme we've done during the trial where the 2D and 3D versions were shot at the same time with the 2D being taken from one of the 3D cameras. The cameras were mounted on mirror rigs and for those interested in the details, these were a 3ality Technica Atom and a P+S TECHNIK Freestyle rig, each fitted with two RED Epic cameras and Angenieux Optimo matched lenses.

This is what Philipp Blaubach, the director of photography (DoP) working on Mr Stink, thought of idea to shoot in 3D:

It was a great opportunity for me to shoot a film that has been specifically designed for 3D. As a cinematographer it is a very different approach both logistically and creatively, and it was important in preproduction to work out the do's and don'ts. Having a close collaboration with the stereographer and the director meant we really embraced the strengths of 3D and found a visual style that works especially for this comedy genre. We liked slightly cartoonish and quirky compositions, like in the films of Wes Anderson or the Coen Brothers, and the fact that 3D works particularly well with wide angles even for close ups suited the style we were after perfectly.

Chris Parks from Vision3 was the stereo supervisor on the programme and also commented;

The choice of rigs and cameras was determined by a number of factors. We wanted to be able to change setups quickly so we chose to use zooms as variable primes. We also wanted a reasonably small and light rig so we could be more mobile and wasn't too off-putting to actors. We also wanted it to be cost effective so that on certain days we could afford to bring in a second unit. The Atom allowed us to put on a larger mirror box so the DoP could use a 16mm lens with the Epic at five thousand. For monitoring we used a 46in JVC as we felt it was important for the director and DoP to be able to see the playback in as near to a real world situation as possible.

Mr Stink was framed for a wider aspect ratio than the normal 16:9. Philipp shot in the cinema aspect ratio that's sometimes referred to as 21:9 but more accurately it was actually 2.35:1. This gives black bars at the top and bottom that effectively become a new screen boundary. However as it's only an electronic boundary that allowed us to try some interesting effects.

Philipp said;

We composed the film for a 2.35 aspect ratio and during the depth grade there were a couple of instances where we could move the action into negative space and virtually make it overlap the letterbox. The 3D is especially effective in those moments as you feel the objects literally coming into your living room.

Framing for 2.35:1 (3D is displayed using anaglyph if anyone wants a quick preview but, the programme will not be transmitted in anaglyph).

As I said earlier the programme was shot using a single camera rig with an occasional second rig. This is different to the multi-camera set-ups we've used for the studio and live programmes that have been in the trail so far. This meant that instead of the stereographer adjusting each camera to match the 3D depth during the shoot, a 'depth grade' process was added to the final post-production stage.

Just like a colour matching or grading session that adjusts the colour and exposure of each shot to make them match, the depth grade matches the amount of 3D in each shot so there are no sudden jumps on shot changes.

Again for interest, the programme used the company ONSIGHT's 'Mistika' equipment to carry out the colour and depth grade with colourist David Gonzalez Lozano and Philipp Blaubach (the DoP) along with Matthew Smith who was the stereographer on the project working under Chris.

Matthew was responsible for the on-set Stereo 3D decisions working closely with the director and DoP and followed this through to the depth grading session during the final post-production.

The last time I saw the programme was just before the final colour and depth grading sessions, so I won't see the final results until it's transmitted.

As usual I am really keen to get your reactions to the programme and what you thought of the 3D but I will be away over Christmas and for a week in the New Year so replies to comments may not be prompt until I'm back around 8 or 9 January. In the mean time I wish you all a very, very merry Christmas and a happy new year - in advance!

    Hi everyone

    I've spoken to the BBC Press Office about the future of the BBC HD channels and they have supplied the following info:

    Simon Smith, head of TV Operations has replied: There will be an announcement soon confirming the date when the DQF decision to close the BBC HD channel and create instead a HD version of BBC Two will be implemented. After that date, there will be a period of time when the only way to view programmes made for BBC Three and BBC Four in HD will be to do so via the BBC iPlayer.
    BBC Vision and BBC Distribution are currently working on options for extending our HD channel portfolio and securing the future delivery to audiences of all the BBC's HD and 3D programmes. These have yet to go through the normal financial and governance processes, but as soon as there is any news we will share it.

    We will update when we have more news.

    Thanks

    Eliza, if BBC HD is to close down in favour of BBC 2 then I think that's a mistake. However, if it must close down then a better choice of an alternative HD channel would be BBC 4 which generally has better programming than BBC 2 and certainly has programs that are more suited to delivery in HD and/or 5.1 sound. That's just my opinion but shouldn't the BBC Trust do some sort of survey of your HD viewer's programme preferences before making this change?

    Andy, on the subject of 5.1 sound, I've noticed this morning that the BBC HD preview loop is not switching to 5.1. I first noticed when the sound test card came on at about 0815 and it wasn't playing the LFE channel but it's also quite apparent when the BBC HD Ident plays; it has much less impact than usual. Is there a technical issue today or has it been like this for a while? I'm viewing on freesat HD in the UK - I'm sure it was working fine before Xmas.

    Dear all - I'm back and it's snowing too! Thank you all for the comments. I was very pleased with the 3D for the programme and it looks like most of the comments here are elsewhere suggest you were too.

    Also welcome back Paul - I can't add anything to the comment from Eliza about other HD channels but I can say iPlayer will still show as many programmes as we can in HD no matter what channel - this is only subject to some of the current limits we have to get the programmes through.

    Re the HD preview - I didn't see your post until Sunday and it was OK on satellite Sunday morning - is it back in surround on Freeview now?

    Is the comment in Broadcast "....everyone has finally accepted that 3D TV is dead." from BBC North Controller, Mark Harrison, corporate or personal?

    Doesn't bode well for the future of 3D on the BBC.

    Dear derek500 - thanks for the post. It was as far as all but LG were concerned at CES however lots of autosteroscopic development happening in the U-HD arena. We will have to see!

    Hi Andy, I'm still not getting 5.1 Surround on my freesat. I've still got the same Yamaha A/V amp I took to Portugal in 2008 but it's working fine for all other sources of 5.1 (except AAC). For the BBC HD soundcheck, Wimbledon, etc. the Amp always used to switch-over automatically but it seems to be stuck on stereo now; just checked on the testcard again - still no joy. Thinking back, I can't remember the last time that I'm certain that it was coming out on my freesat in 5.1 although I'm sure it wasn't too long ago, has there been a recent change of codec?

    Oops ignore my last, someone's dusted round the back and knocked out the optical cable. It's coming through in 5.1 loud and clear now I've put it back in! Cheers, Paul

    As there are not many blogs on the BBC on 3D, could you please make sure this post is kept open for comments and will not be subject to the new 1 week rule of the BBC Internet Blog

    Yes, Paul, thanks. But mainly US posters who don't get the range and depth of broadcast 3D that is available in the UK and are relying on buying/renting blu-rays.

    Still Twitter is full of people watching Africa in 3D. As bad as all those watching SD on an HD TV and think they're watching in HD!!

    Ah, at last I've found a thread on 3D!
    I was posting on the Points of View board.
    Trying to find out what the future policy is of the BBC
    Their efforts so far have been excellent & really enjoyed the Summer Olympics & tennis & Last Night. Didn't watch Mr Stink as the Radio Times did not mention the 3D bit!! Shame.
    Could do with a re-run?
    Are there any more programmes in the pipeline?
