Cine film
Have you got old super 8/double 8/16mm films lying around, which you want to digitize? Digitizing 8mm cine films yourself is possible. Although the quality which is gained is surprisingly less than when it is done by professionals. We explain the different ways of digitizing and give some advise for what you need for the digitizing.

Doing it yourself versus letting a professional do it

1. Digitizing super 8 on DVD via the projection screen

The easiest, but the worst method to digitize your precious super 8 or 8mm film to DVD, is by projecting on a projecting screen (or a white piece of paper) and capturing the image with a camera. The camera can be attached on a DVD recorder or a computer to capture the images. Then the film is burnt on a DVD. Flickering images, a clear hotspot, less contrast and colour difference are in this method almost always the consequence.

2. Digitizing 8mm via glass screen

Another method to digitize cine film, for instance digitizing 16mm to DVD, is by means of a glass screen. The projector projects the image on a tilted mirror and afterwards on the glass screen. If you use a consumer camera without variable shutter time you will see flickering of the image. A clear hotspot is unavoidable with this method, except when you zoom really closely on the image which causes at least loss of 25% of the image. Colour difference and clearly less sharpness and contrast are the most common complaints when it comes to digitizing cine film.

3. Letting a professional digitize

Would you like to let a professional digitize the cine films? Let someone digitize in a high quality on DVD? And for an affordable price?

Do not be tempted to digitize and digitize your cine film to DVD with old telecine scanners from Sony (BM2100), Elmo (TRV) and Fumeo. These telecine scanners from the '80s only have a few simple VHS cameras with 240 screen lines. Our telecine recorder with a professional, industrial camera reaches a resolution of 800 screen lines!

The professional telecine recorders use a industrial camera and a modified projector or an especially designed telecine scanner. Both give an exellent result. The difference between telecine scanners and modified projectors is not visible. The difference can only be measured with an oscilloscope.

Most professional telecine recorders make use of the Hitachi HV D30P cameras. The flash scan of MWA, some recorders of moviestuff and the modified projectors from different providers make use of this camera. The prices of telecine recorders for 8mm and Super 8 cine films vary from about € 4.500,- to € 135.000,-

Van Eck Video Services makes use of a modified telecine scanner, which provide the highest quality scans, to digitize cine films, Super 8 and double 8. Our cine film scanners take a seperate picture of every image in a 1024×768 pixel resolution.

Unlike film scanners from last generation our film scanner has no a shutter, or genlock synchronisation. Each seperate image is digitized, by a separate photo. With this technique we prevent synchronisation problems in the film scanner. This way is better ,compared to the use of normal video cameras, like the Hitachi (D30P). These cameras are not triggered as the image passes, but require to be especially adjusted with special gen lock synchronisation and require a quick closing time.

To reach the standard daylight temperature of 5.000 Kelvin we supplied our scanner with an adjustable LUMILED HQ light source. Because of this, the flicking of the cine film and the movement blur are definitely history. Super 8 or 8mm will not live eternally. That is why we have great care when we put your precious cine film on hard disc, DVD or Blu-Ray

Burning a film on DVD has yet another advantage. We can make menus which gives the user direct view of the desired scene. Searching and scouring are definitely history because of this. To guarantee an optimal quality for your digitized cine film we never burn more than 2 hours on just one DVD.

Transfer your films yourself

In this explenation we are going to make use of a tele screen or glasscreen.
The glasscreens van Doornen give the best results. We advice the hama 3012 telescreens as the best purchase.

Place the projector at the side of the telescreen. Place the camera in front of it (see the next picture)



It is important that the speed of the projector is put on 16,66 images per second for a projector with a three-shutter (which most projectors have) and 25 frames per second for a projector with a double-shutter. This is to minimalize the flicking of the image. This requires a projector with continuous adjustable speed.

There are actually 2 groups of film projectors with continuous adjustable speed

1) Analog adjustable . There is no electrical control in here. The speed is managed by the amount of electricity the motor gets. This works, only is the speed not constant. When the projector heats, or the power on the reels changes (for instance when the film is played a part) the speed will vary. So practically it will be necessary to change the speed a little during the transfer.

An example from an analogue constantly adjustable projector is the Elmo GP-E projector. The most projectors in this class have a price between €110,- and € 160,-

2) Digitally adjustable. There is a electronic control with feedback. This feedback makes sure the projector will run at a constant speed. An example of such a projector is the Braun Visacustic 2000. There aren't a lot op projectors that have 16,66 frames per second with electronic feedback. This type of projector is also very expensive. But we have made electronic conversion kits to make this possible.

When your projector has no adjustable speed, it is possible to modify this with a few changes in the electronics. We sell conversion kits for this. we have these conversion kits now:

The speed of the projector can be measured by the next device: Speed-o-meter - ELV RC200

The frames of the camera can be put from the camera on the computer for the finishing touch and export to files, DVD or Blu-Rays

You can transfer sound on many different ways.

1. Taking up sound via the computer. This is the easiest.Although you will have to synchronize the sound with the film afterwards. You can connect the DIN connection from the projector (round with 5 pins) on the audio entrance from the soundcard from the PC with these 2 cables.
overview 5p DIN plug - 4x RCA plug contra Cable 3.5mm stereo male - 2x RCA male 1,50m



2. Connecting sound via the camera. The benefit of this is that the sound stays synchronised with the film. Your camera will need an external microphone input connector. You will also need an adapter to adapt the signal strength of the sound, because the signal strength from film projectors is not suitable to directly plug in the camera microphone-entrance. You can use an audio-strengthener for this, or a specially made converter, Bauer film projector audio out converting to microphone in.

 

Finishing the video

After the video ís recorded by the camera, there are some post-processing steps. The most important is to correct the speed. The speed at which the film is recorded by the 8 mm film camera is different from the speed in which it is digitized. The formula to calculate the correct rate conversion is: 100 * (1 / (digitized speed / original speed)) %. For example, a movie recorded at 18 frames per second and digitized at 16.66 frames per second needs o be corrected by a factor of 108%.

Table with most common speeds:

original speed digitized speed rate converstion factor
16 16,666 96 %
18 16,666 108 %
24 16,666 144 %
