AV Broadcast Legacy Video Tape Transfer Services

OUR BROADCAST VIDEO TRANSFER SERVICES ARE HIGHLY RECOMMENDED

Our preservation AV archive transfer services are perfect for capturing content from professional broadcast tapes and converting to new digital formats can convert the following specifications.

10 bit uncompressed files in either AVI or Quicktime codecs. Pro-Res 422, FFV1, H.264 MOV, H.264 MP4, DVD and Blu-Ray discs. These can be converted to storage media, cloud or your own server.

We can support both PAL and NTSC tape formats for DVCam, MiniDV, HDV, Betacam SP SX, Digibeta, Sony IMX, DVCPro, VHS, U-Matic.

There are only three ways to preserve analogue content:

1. Conserve the originals;

2. Make copies of the originals, using the same or similar technology (dubbing analogue content onto new analogue carriers); and

3. Move the content onto new technology.

Alternatively we can provide authored DVD and Blu-Rays with menu suppliments. Our services are suited for the long term archival of video that will support your archive preservation requirements.

FILE SIZES: Digital video produces vast amount of data. Using PAL-SD as an example, image only no audio and stored as YUV422 16bit with a resolution of 720x576 and applying no compression would result in a file size of 1.15gb per minute. For 10bit would represent 1.4gb per minute. Therefore we ask for a hard drive suitable for storage on all orders.

10BIT UNCOMPRESSED AVI/MOV: For long-term archiving purposes, the most important factor for choosing a codec is to be able to preserve the content adequately in a stable manner and its vendor-independent accessibility over time.

AVI is currently recommended by The National Archives for meeting the requirements suitable for preservation archiving of video tapes.

FFV1 - LOSSLESS COMPRESSION: We offer several choices of archival conversions to suit your requirements. FFV1 is a lossless compression format meaning there are compression algorithms which reduce the filesize but still preserve every bit in its original state, even after recompressing an infinitive number of times. Think of a Zip file!

PRO-RES & H.264 MPEG4 - LOSSY ENCODING:Apple Pro-Res is perfectly suitable for video editing and ideal for MAC users. But for archival reasons due to being lossy it is not recommended for archival purposes. The same is applied to MPEG4 whereby this format is perfect for viewable copies of originals.

Onion Skin Archive Book Scanning - What is this and how do we process the pages?

CURRENT BOOK SCANNNING PROJECT. We are currently working on a very large archive of old books that require HQ scanning to Archival TIFF images. Once processed, these images will be prepared to PDF with OCR (optical character recognition) for a complete searchable output. The difficulty in this order, is the books are prepared using a medium called Onion Skin Paper. Whilst we are very confident in preparing this type of medium, it is very important to be aware that there are risks with scanning, given the sometimes-fragile nature of the paper. Tears and rips can occur, so a very gentle white glove approach is required. Equally, with the nature of onion skin, the paper is very translucent which requires a sheet of white paper to be placed under each page before scanning. This then grants a very good HQ image that we can work with. WHAT IS ONION SKIN PAPER? Onion skin paper is a type of very light weight, almost translucent paper that ...

The Repair Shop - How To Spot A Ferrotype Camera 1855-1940s

After watching The Repair Shop on BBC1 restore a beautiful and rather rare ferrotype camera I thought a blog on the process would be interesting. Not only did they repair but they managed to have the camera working, taking photographs. This was very inspirational given the age of the camera. ABOUT FERROTYPE PROCESS Ferrotypes first appeared in America in the 1850s, but didn’t become popular in Britain until the 1870s. They were still being made by while-you-wait street photographers as late as the 1950s. The ferrotype process was a variation of the collodion positive, and used a similar process to wet plate photography . A very underexposed negative image was produced on a thin iron plate. It was blackened by painting, lacquering or enamelling, and coated with a collodion photographic emulsion. The dark background gave the resulting image the appearance of a positive. Unlike collodion positives, ferrotypes did not need mounting in a case to produce a positi...

How to Digitise Glass Plate Negatives | Oxford Archiving

The Preservation of The Curnock Glass Plate Negatives Introduction Our services ( @OxfordDuplicat1 ) are highly recommended in the UK for specialist photographic film scanning. Trusted to our company, we are preparing The Curnock glass plate collection, held at Oxford Brookes University and part of the @MethodistGB collection. Almost all archives possess some type of photographic collection. Many individuals typically think of “photographs” as plastic-based negatives and slides; but these photographic techniques are relatively recent inventions. Prior to the invention of cellulose nitrate film in 1903, photographic emulsions were made on glass supports. These glass supports are typically referred to as glass plate negatives. The term “glass plate negative” refers to two separate formats: the collodion wet plate negative and the gelatin dry plate. Both of these formats consist of a light sensitive emulsion that is fixed to the glass plate base with a binder. Dozens of photog...
