Quality improvement of (old and new) films and videos Enhance4.jpg (16407 bytes)

Nederlandse versie
Do you have film or video material that is unclear, wobbly, vague, dull and / or plays too fast or too slow? If so then we can help you to drastically improve this material!
Using special software, we can significantly improve your digital media in quality, including:
  • Smart contrast, brightness and color correction.
  • Intelligent sharpening techniques.
  • Rigorous image motion stabilization.
  • Upscaling to a higher resolution (eg jacking up to HD quality)
  • Speed correction (eg playing old movies at the correct speed).
  • Coloring black and white films by means of Artificial Intelligence
  • Linking multiple films and / or scenes.
  • All kinds of other filtering and improvement techniques.
  • Recently also revolutionary quality improvement with A.I.

Please note that this is a completely different type of service than, for example, digitizing your old 8mm  films to CD or DVD.






Basic tariff: € 15,00 for each video file or separate fragment (starting tariff, regardless of file length).
In addition, there is a charge per type of service for each block of 10 seconds (rounded up to the nearest multiple of 10 seconds):

Service A: Standard film enhancement service:

  • Quality enhancement of contrast, brightness, colour and sharpness
  • De-noising and dust removal of damaged and/or dusty footage
  • Motion-stabilisation of jerky, wobbly film material:                € 1,50 per block.

Service B: Sublime quality enhancement:

  • Rigorous quality enhancement and upscaling using Artificial Intelligence: € 1,25 per block
    for SD to HD and € 2,00 per block for SD/HD to UHD (4K).

Service C: Speed correction:

  • Speed correction (e.g. from 15 to 25 frames per second): € 1,00 per block.

Service D: Colorization of B&W film:

  • Artificial colourization of black & white films using A.I.: € 5,00 per minute.

Service E: Linking of multiple film fragments:

  • Linking of multiple video fragments into 1 file: € 5,00 per link.

For videos with a duration of longer than 5 minutes a discount of 1% applies on Services A to F for every additional minute, up to a maximum discount of 40%.

Example-1: You provide a digitalized film of 3 minutes en want to use Service A and B. The tariff will then be based on a file length of 180 seconds (i.e. 18 blocks).
Tariff: € 15,00 + 18 x (€ 1,50 + € 1,25) = Total: € 64,50

Example-2: You provide 2 video files that need to be linked of respectively 50 seconds and 75 seconds and select Service A, B and C. The tariff will then be based on a file length of (rounded-up to) 130 seconds (i.e. 13 blocks).
Tariff: € 15,00 + 13 x (€ 1,50 + € 1,25 + € 1,00) + € 5,00 = Total: € 63,75

Example-3: You provide a digitalized film of 20 minutes and want to use Service A. The tariff will then be based on a file length of 1200 seconds (i.e. 120 blocks).
Tariff: € 15,00 + 120 x € 1,50 = Total: € 195,00 - 15% discount = € 165,75

You can also first decide to give us a trial assignment. We will then produce a video file of at minimum 10 seconden against afore mentioned tariffs. If you then decide to give us your definite order for the entire film(s) then the costs for the trial film will be deducted from your final invoice.

We will communicate in person with you per e-mail in order to avoid any misunderstandings and to ensure that you get the desired final product! Our video-enhancement service deserves utmost attention and is very labour-intensive. Most of the process is not automated but in stead requires a lot of manual activity.

Note: SD is 360p to 720p, HD is 1080p and UHD (4K) is 2160p.

You inform us by e-mail of the following:
  • The duration of the digitized film material (in seconds).
  • A description of the subject.
  • The required type of service (A, B, C, D, and/or E).
  • The desired format. By default we deliver the final product in mp4 (h264) format to you.
  • A statement that you are the license holder or that it involves public domain material.
  • A description of possible special wishes (video format, fragment linking order etc.)

Subsequently we will provide you with an offer by e-mail and an upload-link in order to send your video material electronicly to us. Upload can also be done in 'unlisted' mode to Youtube or via WeTransfer. After receipt of your payment we will commence producing your video(s); this takes 2 to 10 working days dependent on the complexity of your order and other workload.
After completion you will receive a WeTransfer download-link to obtain the enhanced video material.

  • You may only offer digital quality improvement material to us if you are legally entitled or if the material is license-free (public domain).
  • We will not accept objectionable material. This concerns, among other things, sexually oriented material, violence, privacy-transcending material, etc.
  • We will also not accept feature films, TV series or Film / TV productions (or fragments thereof), unless you as an organization can demonstrate that you have the rights thereof.
You do not need to read this, but for those interested in technology, here is an explanation of the quality improvement methods that we use:

Contrast and brightness enhancement:

A smart filter calculates the ratio between light and dark per scene. This is done by generating a histogram that corrects brightness and contrast. This happens not only for the entire image but also for elements in the image. A white shirt, for example, ensures that the folds and pleats remain visible, even when the brightness of the rest of the image needs to be intensified.

On the left is the original, faded image, in the middle is a roughly corrected image and on the right shows what our filter does! Pay special attention to the white sleeve and the blouse: the pleats remain visible!

Upscaling to higher resolution:

This function is intended to upscale video in standard image quality (such as with images with 640 x 480 pixels) to, for example, HD format (1920 x 1080 pixels). With intelligent software, image pixels are split into even smaller image particles. For example, a bevel is rendered less coarse and jagged. Previous and subsequent images are also used to achieve the best result:

One of the most annoying experiences when watching (amateur) films and videos is a choppy, wobbly image. Even if it is not immediately noticeable, troubled images will cause the brain to do more to process the images, which causes fatigue. The stabilization software we use ensures that all images are displayed stably and smoothly. In this example, compare our results (right) with the original image (left):


Speed correction:

In early years (until circa 1935), movies were recorded at just 15 to 18 frames per second (fps). Later that became 24 fps (and with television 25 fps). Many modern projectors cannot play 18 fps images and use 24 fps instead. The result is that everything moves 33.3% too fast. People on the street seem to run too fast. To convert 18 fps to 24 (or 25) fps, additional intermediate images can be generated with smart software, so that the film looks smooth again and is displayed correctly. This process requires great computing power. To correct 1 second of film, our computer is stamping for over a minute. However, the result is astonishing. This technique can also be used to convert ordinary film images into smooth, non-choppy slow-motion images, or to convert images from, for example, 25 fps to 50 fps, 100 fps or higher.

Left and right are two consecutive images (frames) of the original video. In between is an intermediate image generated by the software, the head rotation being about half of the source images.

Colourization of black & white film:

The possibility to artificially colourize (old) black & white films has increased rapidly in the past year due to the arrival of Artificial Intelligence (A.I.). Various parties are busy developing software for this.
We offer a very affordable film colouring service. Since it does not matter much whether a film of 10 seconds or 10 minutes is colourized, we have (for the time being) opted for a fixed rate per block of 10 minutes. We expect that the software will yield significantly better results in the short term. Below is an example of a colorized film:

Quality enhancement and Upscaling to higher resolution using A.I.:

This function is intended to upscale video in standard image quality (such as with images with 640 x 480 pixels) to, for example, HD format (1920 x 1080 pixels) or even 4K. With the help of Artificial Intelligence the film is drastically improved in quality. This new technology, Service E, has been available since 2020 and is an alternative to our original Service B.
The reason that service E is significantly more expensive than B is that this technique requires enormous computing power. The conversion from SD (480 or 720p) to HD (1080p) requires 1 hour of processor time per minute of film. Conversion from HD (1080p) to UHD (2160p) requires approximately 4 hours per minute of video!


Final comment:

Reasonable to good source material can be significantly improved in quality. Don't expect miracles though. After all, beautiful HD material cannot be generated from 'nothing'. Especially if the source material is poor (blurry, low resolution and / or with a lot of digitization 'artifacts' or noise) then the English expression applies: "Garbage in, garbage out). If we believe that your material cannot achieve good results, then we will report this to you in advance.
