Making Video Look Like Film – A Digital Filmmaker’s Guide

Making Video Look Like Film – A Digital Filmmaker’s Guide

You have your script. You have your digital digicam and laptop enhancing software program. You have actors, a crew, and a few locations. Now you start to shoot your “virtual” movie. Although the “filmmaking procedure” defined in right here makes use of the “movie” word, what we are simply speaking approximately is the general project, now no longer the medium on which it’s miles shot. In current years many conventional filmmakers have made the soar from movie to virtual video as have many tv series. The motives are clean: even the use of the best high-satisfactory virtual video codecs to be had, the price financial savings over capturing conventional 35mm movie aren’t to be ignored, in addition to the truth that nowadays many conventional movie shoots use a “virtual intermediate” (a elaborate manner of pronouncing the movie photos is scanned body via way of means of body into a sequence of virtual nevertheless pics) to offer colour correction, upload unique effects (if wished), and withinside the case of everyday tv series, are output at once to tape or disc and by no means see movie once more.

In the unbiased movie world, those current adjustments have had an widespread effect at the affordability of manufacturing. “Prosumer” virtual video cameras starting from $one thousand as much as $10,000 offer distinctly clean, clean pics. Also extraordinarily lower priced are laptop hardware and enhancing software program which give unmarried-supply solutions, now no longer handiest for enhancing of pics, however additionally colour correction, unique effects, sound mixing, and DVD authoring. Just some brief years ago, a feature-period unbiased movie shot in 16mm colour movie might have widespread expenses without a doubt withinside the rental/buy of a right digital digicam; the price of a movie (four hundred foot reels at greater than $ninety every), processing, poor reducing and colour correction expenses, and all this even IF one selected to output to videotape and edit the very last photos there (a l. a. Robert Rodriguez’s “El Mariachi”). Now a unmarried mini-DV tape costing around $four can file as much as an hour of photos. Portable laptops and/or proprietary difficult pressure structures can file at once to disk layout prepared for enhancing with out even the want for shooting from tape. However, one truth nevertheless remains – you’re nevertheless capturing “video” and, unfortunately, video does now no longer appearance like “movie”. There are numerous motives why:

FRAME RATE

Film is shot at 24 frames in keeping with second (fps); video is shot at 30fps (even though due to the fact widespread video is interlaced, i.e. every body is made from fields which might be scanned at odd/even intervals, it absolutely seems greater like 60 fps). The more frames of video offer greater element in an item or person’s motion, making the picturegraph appearance greater sensible in nature However, as a society we have got grow to be so used to the 24fps appearance of movie that video does now no longer create the “suspension of disbelief” whilst we watch it.

IMAGE CLARITY

Standard definition DV video makes use of a body length of 720×480 pixels. Doing the math, that is a paltry 345,six hundred pixels to breed every body. If published on a sheet of picturegraph paper at three hundred dots in keeping with inch (DPI – the minimal quantity wished for a clean published picturegraph), it’d slightly be 2 ½ inches huge. By comparison, present day virtual nevertheless cameras now perform withinside the five megapixel variety and up, presenting 14 instances greater picturegraph records than widespread video. This methods the readability of 35mm movie, which, even though now no longer having a selected pixel count, may be magnified and blown as much as large proportions (i.e. 8×10 picturegraph or projected onto a 30 foot screen). However, more recent High Definition (HD) video codecs offer plenty sharper pics (the 2 maximum famous codecs are 720×1280 pixels and 1080×1920 pixels).

IMAGE QUALITY

Although movie technically has greater decision than widespread video, the general appearance of the picturegraph is “softer”. This is because of colours at the movie emulsion mixing progressively from one to another, while every pixel in widespread video has particular obstacles among itself and its neighbors. New virtual cameras have unique circuitry to assist create smoother pics, particularly in regions of colour than method pores and skin tones.

ASPECT RATIO

Until recently, video changed into shot with a photograph top that changed into ¾ of it is width (regularly called four:three, or in movie terms, 1.33:1) For years, movie has been projected with thing ratios starting from 1.85:1 to 2.35:1. New excessive definition tv units and transportable DVD gamers use a compromise thing ratio of 16:nine (or 1.78:1, near the 1.85:1 quantity stated above). This does now no longer have as plenty of an impact because the gadgets stated above, but it is going a protracted manner to promoting the “appearance” of video as movie.

DEPTH OF FIELD

This is quite a number distances from the digital digicam lens wherein an item remains in cognizance. It is primarily based totally on numerous elements, the maximum crucial of which might be the real body (in movie) or CCD (in video) length. The large the body surface, the much less intensity of subject at a selected aperature putting. Traditional movie cameras get hold of mild thru a lens onto a rectangular this is 35mm (1.four”) diagonal. Many of present day smaller DV cameras use 1/three” or maybe ¼” diagonal CCDs. This is why a conventional 35mm movie picturegraph could have a topic in cognizance and the on the spot historical past out of cognizance. This impact additionally facilitates separate the foreground individual or item and permits the filmmaker to pressure the target target market to pay attention on a selected a part of a scene. Video cameras have a tendency to permit greater objects (foreground and historical past) be in cognizance on the equal time.

Another manner to generate a “cinematic” appearance to a shifting picturegraph is via way of means of shifting the digital digicam rather than the use of the zoom lens. Except for a short length for the duration of the 1970s, zooming withinside the movie network has been not often used. Instead, the procedure of bodily shifting the digital digicam facilitates create a greater three-d sense and is greater intently associated with what we study thru our eyes each day (recall our eyes cannot “zoom” the manner a digital digicam lens can). Zooms also are greater generally utilized in tv programs (news, sports, communicate shows, etc.).

So, what are we able to do to conquer the “video” appearance in prefer of the greater pleasing “movie” appearance? First of all, the choice of a right digital digicam is the key. Many more recent cameras (beginning with the groundbreaking Panasonic DVX-one hundred series) are able to capturing at 24fps. The ensuing set of pics is then laid down onto DV videotape the use of a three:2 pulldown approach (just like how conventional movie at 24fps is transformed to 60 interlaced fields). This permits like minded playback on any widespread DV digital digicam or deck. The byproduct of the 24p mode is likewise that the picturegraph is scanned progressively, which yields a barely sharper picturegraph than the standard interlaced video body.

Other cameras simply out at the market (which includes the JVC HD100 and the Sony FX-1) shoot in HDV mode (an abbreviation for High Definition DV), which once more makes use of a widespread DV videotape to file greater pixels in keeping with every body. The disadvantage is this gadget makes use of MPEG-2 compression, a technique of compacting records that is utilized in widespread DVD discs and gamers. Because of the massive quantity of records that has to be “squeezed” onto the tape, occasional artifacts can appear, particularly in scenes with a whole lot of motion.

Finally, genuine HD cameras which includes the Panasonic HVX-2 hundred offer “genuine” HD recording capability, but right here the price of the recording media starts to rise. Although the HVX-2 hundred has a mini-DV tape pressure integrated, so one can understand the better high-satisfactory pics, one have to use Panasonic’s proprietary “P2” garage gadget, which statistics the records onto a sequence of detachable reminiscence playing cards. At this point, those playing cards are nevertheless extraordinarily expensive, but as generation improves and reminiscence fee falls, this can show greater lower priced withinside the future.

When capturing on video, numerous key elements can assist keep away from the “video” appearance. The first one is to keep away from overexposing even a part of the body. Overexposed movie reacts plenty in a different way than overexposed video, which has a tendency to sharply lose all colour and generates a noticeable “blooming” alongside the rims of the overexposed a part of the scene. By final the iris of the digital digicam ½ to at least one complete f-stop, you could convey doubtlessly overexposed highlights down right into a usable variety. With the colour correction gear in maximum important enhancing programs, the picturegraph may be brightened a piece later if necessary. Also, a number of the more recent DV cameras have selectable gamma settings which reveal the mid-tones of the scene in one of a kind approaches to higher suit the manner movie reacts to mild. Also, using soft, subtle mild is extraordinarily crucial – this facilitates maintain shadows to a minimal and softens the picturegraph this is captured via way of means of the digital digicam’s CCDs.

The thing ratio of your video body is distinctly smooth to change. First, you could shoot complete-body, then upload black bars throughout the pinnacle and backside whilst you edit. Although this offers the video a “widescreen appearance”, you’ve got got basically thrown out 25% of your picturegraph records. Many DV cameras have 16:nine widescreen modes, even though they range in how that is accomplished. Some without a doubt upload the black bars throughout the pinnacle and backside and file the body that manner; others will flip off the pinnacle and backside quantities in their CCDs and “squeeze” the relaxation of the records right into a complete body (called anamorphic), which yields barely higher effects. The ensuing “squeezed” body is then restored to regular thing whilst considered on a 16:nine display or projector, which then “stretches” the body out to its regular width. With widespread definition DV cameras, the best high-satisfactory approach for acquiring a 16:nine picturegraph is to apply an anamorphic lens, which optically squeezes the picturegraph to match right into a four:three body, permitting you to apply all the to be had pixels at the digital digicam’s CCD. Unfortunately, anamorphic lenses can price upwards of $800 or greater. With Some of the brand new breed of HDV and genuine HD cameras, the CCDs inside them absolutely have 16:nine thing ratios and the pixels to suit.

Unfortunately it’s miles extraordinarily hard to suit the slender intensity of subject appearance of movie. Even massive expert cameras with ¾” CCDs nevertheless have problem matching that of 35mm movie. There are different elements which have an effect on intensity of subject, but, one in all that is the aperature putting at the digital digicam lens (additionally called the iris). The greater open the iris, the greater slender the intensity of subject. So even if you are the use of a whole lot of mild on a selected scene, you could pressure your digital digicam to shoot with a narrower intensity of subject via way of means of the use of integrated impartial density filters, which maximum prosumer cameras have, or via way of means of placing impartial density clear out out in the front of the lens to darken the picturegraph getting into the lens. Another component is the focal period, or how some distance the digital digicam is zoomed in to a topic. The greater telephoto a zoom putting is, the greater essential the intensity of subject. However, this have to be used carefully; via way of means of putting in the digital digicam too some distance farfar from the situation and zooming too some distance in, it could purpose the historical past, despite the fact that barely out of cognizance, to appear towards the situation than it’s miles in reality.

Camera motion is an problem that may be solved both with a bigger budget, a piece of ingenuity, or a bit of both. Simple handheld moves are the cheapest, however additionally require a few talent, despite the fact that the ensuing shot is meant to appearance “a piece shaky”. Simulating using dollies may be achieved withinside the age-vintage way of life of the use of an vintage wheelchair, setting the digital digicam and/or operator on it, and rolling it alongside a distinctly easy surface. For excessive perspective shots, not anything beats a crane; even lifting the digital digicam up 10-12 toes above your scene, particularly with the lens set as huge as possible, will acquire astounding effects. Again, with a piece of talent you may assemble a easy crane gadget the use of a few 2x4s, a journey to the hardware keep and a few vintage workout weights. However, a few new lower priced (around $three hundred) crane structures have grow to be to be had in current years. There are various forms of digital digicam stabilization structures (i.e. “steadicam”), a few as easy as a counterweighted platform requiring the operator to keep all of the weight with his/her arm; others come geared up with vests and spring structures which switch the load to the frame and permit for even smoother motion. Again, the use of structures like this take practice, however can acquire astounding effects whilst carried out correctly.

By taking all of those gadgets into consideration whilst capturing, possible create a plausible movie appearance that is sufficient to “fool” maximum audiences. Of course, in the end the general manufacturing price of the shoot (lighting, sound, acting, set design, makeup, etc.) may also decide how “expert” the completed movie is, no matter whether or not it seems like movie or video.
