A spot recorded with an iPhone. This is the spot produced by an NGO that seeks to raise New York on the amount of food wasted in New York and the number of hungry in the city. Here are the piece:

Beneath the apparent simplicity that implies that this spot is recorded entirely with an iPhone, there is a substantial technological framework. The prestigious studio The Mill , responsible for the audiovisual work as detailed in its web was made this spot.

Indeed the base sequence shot of the spot was shot entirely with an iPhone in a New York subway station. Later in postproduction CGI should be incorporated in this case was the crowd of apples that come in an avalanche of wagons of the train. presente en toda la escena provocan una distorsión difícil de salvar por los softwares de tracking así que The Mill ideó un “rig”o armazón de cámaras , en cocreto  tres Canon 5D MKII, que situadas fijas en la estación grababan sincronizadas en todo momento la posición del iPhone. For this integration was needed to make a tracking of the whole scene, which was quite difficult to do directly with the material recorded with the iPhone. The compression artifacts and the CMOS rolling shutter present in the whole scene cause a distortion difficult to save for tracking softwares so The Mill devised a "rig" or frame cameras, Canon 5D MKII cocreto three, which still placed at the station recorded synchronized at all times the position of the iPhone. This in turn was easy to locate by tracking software thanks to LED lights clearly marking its position in space. In this way the tracking is greatly simplifició although it was necessary to correct by hand, frame by frame as it happens almost always.

For realistic textured apples used an HDRI map generated by a camera 360 ° x180 °, in particular a SpheronVR which also has an amazing 26f stops, camera any day deserve an article on this blog.

This whole process can be seen in detail in this "breakdown"

Finally, post-production to mimic the compression artifacts and color correction did the rest to provide that sense of realism.

So, yes, a spot shot with an iPhone, but there is more behind it to get that "look random" cinéma vérité.

Although this blog is dedicated mostly to everything related to technology and audiovisual postproduction, today I present a useful tool for pre-production processes. y en definitiva todos los recursos propios de cualquier producción audiovisual. This is Celtx , a free software that allows you to organize all tasks related to the preproduction of any audiovisual or entertainment. Celtx is an organizer that allows us to handle scripts, breakdowns, storyboards, filming dates, records of locations, actors, technical, etc ... and ultimately all own resources any audiovisual production.

It is a kind of production schedule allows us to keep on hand and updated each of these resources. Contains tools to make sketches of the shots and camera setup, tools for creating story boards, shooting schedule, script editor ... all this is recorded in a project that we can share with other users or recycled for new projects. It is available for Mac and PC and also in Spanish .

This is one of those little applications that may become indispensable for any editor. This is VideoSpace of Digital Heaven, a company specializing in applications and plugins for Final Cut. Although already an old acquaintance through plugins like Loader , this company has just released version 3 of this application free of charge. With it you can calculate the space it will occupy in our disk any video clip showing the codec, duration, fps and the type of audio. The novelty is that include new codecs supported by Final Cut 7.

It can also be installed as a widget on your Mac, iPhone or iPodTouch or can be accessed online at this link: http://www.videospaceonline.com/
