\chapter{Overview}%\r
\label{cha:camcorders}\r
\r
This document describes the methods used to achieve a "backup type" or intermediate codec\r
for non-edited source video camcorder formats, compatible with and viewable on Bluray hardware players. After you have\r
moved your camcorder media onto a computer disk, you can with some extra effort, transfer them for safekeeping and\r
longer term storage on simple viewable Blu-ray video discs. \r
\r
Transferring camcorder media to digital files on a computer, and next to optical Blu-ray video media is especially\r
important for legacy tape-based camcorders, because tape will degrade over time. You can do this using a combination of\r
free tools on Linux, generic and independent of any NLE. \r
\r
In this case we use and keep interlaced video as on the source or digitized video (PAL 50i, 25 fps) for both DV and HDV\r
formats.  As confirmed by the ffmpeg output below, DV uses 25 Mbps data rate (DV25), is Standard Definition (SD),\r
resolution 720{\texttimes}576, 8 bits color depth 4:2:0, display aspect ratio (DAR) 4:3 while HDV is High Definition HD video,\r
resolution 1440{\texttimes}1080, DAR 16:9, 8 bits color depth 4:2:0. \r
\r
We utilize or keep relative low MPEG-2 video compression at the same bit-rate 25 Mbps as the original video recorded\r
onto the source tapes. That is about 13 GB per hour video and audio in total, and about 3 hours playtime with 40 GB\r
BD-video size (of max 46.5 GB) on each 50 GB BD-R DL Blu-ray disc. Audio is transcoded to uncompressed LPCM compatible\r
with BD-video. \r
\r
In this how-to we combine \textbf{ffmpeg}, \textbf{tsMuxeR} and \textbf{xorriso} to create the MTS-video stream, to\r
create the Blu-ray ISO image, and to burn the image to Blu-ray video disc. The benefit of using tsMuxer here, is its\r
support of UDF version 2.50 as required by the Blu-ray video standard. Listed next are the possible camcorder video formats on Blu-ray video discs.\r
\r
\begin{itemize}\r
\item \textbf{DV} (1995) transfer to SD-blu-ray video (re-encoding video to mpeg2, re-encoding DV LPCM audio to Blu-ray LPCM) \r
\item \textbf{HDV} (2004) transfer to blu-ray video (copying mpeg2 video, re-encoding MP2 audio to Blu-ray LPCM or AC3) \r
\item \textbf{AVCHD} (2006-current) transfer to Blu-ray video (copying H.264 video and AC3 audio)\r
\end{itemize}\r
\r
An alternative method as described in the CinGG manual, is to use \textit{mkudffs} and \textit{bdwrite} packaged with CinGG, to create the udfs image and burn it to Blu-ray disc using \textit{growisofs} or \textit{dd}. \\\r
{\small \url{https://cinelerra-gg.org/download/CinelerraGG\_Manual/Creating\_Blu\_ray\_Without\_Re.html}}\r
\r
There are other methods described on the internet and there are alternatives to the software programs used here that work as well. \r

\begin{itemize}[noitemsep]\r
\item Composite Audio/Video is encoded on one channel with maximum horizontal resolution 240 (250) dots (or visually\r
resolvable vertical picture lines) for VHS/VHS-C and 280 dots for Video8 (2.7MHz video bandwidth).\r
\item In comparision, horizontal resolution bandwidth for PAL broadcast: 5.0-5.5 MHz, NTSC: 4.2 MHz.\r
\item It is the horizontal resolution that makes the big difference in picture quality since all video formats have the\r
same number of vertical resolution (or visible horizontal scan lines); always 576 for PAL/SECAM and 486 for NTSC.\r
\item RCA (phono) connectors: yellow for composite video, red and white for left and right audio signals.\r
\item 21-pin SCART Euro connector with optional RCA adapter.\r
\item Magnetic tape media in full size VHS (1/2") cassettes, VHS-C (1/4") compact and 8\ mm cassettes.\r
\item Cassette adapters to playback compact VHS-C cassettes on full size VHS decks/players.\r

\item Max visible horizontal resolution is 400 dots for SVHS/SVHS-C and 440 dots for Hi8 systems on high-end VCR\r
machines (4.5 MHz decks). In practice consumer/prosumer camcorder recordings quality vary from about 330-350 dots\r
horizontal resolution (3.5MHz), which is equivalent to analog TV set quality.\r
\item 4-pin mini-DIN S-video connector for Y/C video, red and white RCA line connectors for left and right audio;\r
optional SCART Euro adapter with 4-pin video and RCA audio connectors.\r
\item In comparision, analog Component video (three component YPbPr) has the highest color resolution and is encoded\r
over three channels with green, blue and red RCA connectors (consumer) or with BNC connectors (prosumer), additional red\r

\section{\textbf{Digital video}}%\r
\label{sec:digital}\r
\r
\subsection{\textbf{DV (1995), Digital8 (1999)}}%\r
\label{sub:dv1995}\r
\r
\begin{itemize}[noitemsep]\r
\item DV refers to a family of codecs and tape formats used for storing digital video, especially on MiniDV cassettes, the most popular tape format, or on Digital8 cassettes using a DV codec. \r
\item DV codecs are still sometimes used when dealing with legacy standard definition SD video:\r
 \newline\hspace*{.5cm}PAL:  625i50, 720 {\texttimes} 576 frame size, 25 fps, 8 bit 4:2:0 subsampling\r
 \newline\hspace*{.5cm}NTSC: 525i60, 720 {\texttimes} 480 frame size, 30 fps, 8-bit 4:1:1 subsampling\r
\item The same frame size is used for 4:3 and 16:9 frame aspect ratios, resulting in different pixel aspect ratios for\r
fullscreen and anamorphic widescreen video.\r
\item DV uses lossy, DCT algorithm intraframe video compression 5:1 on a frame-by-frame basis.\r
\item Audio almost exclusively is stored as 16-bit LPCM at 48 kHz sampling rate, 1.5 Mbit/s stereo.\r
\item Data rate is about 25 Mbit/s for video, thus DV25, and an additional 1.5 Mbit/s for PCM audio. \r
\item Total stream is 29 Mbps, or 3.6 MiB/s. The information output is approximately 200 MiB per minute, 12 GiB or 13 GB\r
per hour playtime.\r
\item DV camcorders and decks have IEEE 1394 (FireWire, i.LINK) ports for digital video transfer. \r
\item \textbf{DV50} (Digital-S or D-9 and DVCPRO50) is a 50 Mbit/s variant of DV with improved 4:2:2 chroma subsampling and 3.3:1 compression.  This in effect cuts total record time of any given storage medium in half compared to DV25. \r
\item DV was strongly associated with the transition from analog to digital desktop video production.\r
\item Digital8 equipment recorded in DV format only, but usually could playback Video8 and Hi8 tapes as well, and were\r
also capable to do analog to digital video conversion during playback. \r
\item Most (but not all) modern digital camcorders provided an analog-to-digital\r
"passthrough" capability. This feature fed an analog input signal (usually via S-Video,\r
sometimes RCA) into the camcorder and output a standard DV signal. The camcorder converts the analog signal on-the-fly\r
using a hardware encoder. The input device could be your old analog camcorder (playing 8\ mm or Hi8 tapes), a VHS/VHS-C\r
video player, to convert analog to digital output via Firewire \textbf{dv} file extension.\r
\end{itemize}\r
\r
\subsection{\textbf{DVD-Video} (1996)}%\r
\label{sub:DVD-Video}\r
\r
DVD-Video discs are intended for full-length movies and offer a range of features including the following:\r
\begin{itemize}[noitemsep]\r
\item Playing time: a nominal 133 minutes playing time for DVD-5 or each side of a DVD-10 and 240 minutes for DVD-9 using opposite track path format. In practice playing times are often reduced in favour of improved quality.\r
\item Video encoding: MPEG-2 (\href{mailto:MP@ML}{MP@ML}) or MPEG-1.\r
\item Audio Quality and Languages: Dolby Digital, DTS, MPEG-2 or Linear PCM audio for up to 5.1 channel surround sound.\r
\end{itemize}\r
\r
\begin{itemize}\r
\item To record digital video, DVD-Video uses \href{https://en.wikipedia.org/wiki/H.262/MPEG-2\_Part\_2}{H.262/MPEG-2 Part\r
2} compression at up to 9.8~Mbit/s, maximum of 10.08 Mbit/s can be split amongst audio and video. DVD-Video supports\r
video with a \href{https://en.wikipedia.org/wiki/Color\_depth}{bit depth} of 8 bits per color, encoded as\r
\href{https://en.wikipedia.org/wiki/YCbCr}{YCbCr} with 4:2:0\r
\href{https://en.wikipedia.org/wiki/Chroma\_subsampling}{chroma subsampling}. The H.262/MPEG-2 Part 2 format supports\r
both interlaced and progressive scan content.\r
\item As for lines of horizontal resolution, DVD has about 500. In analog output signal terms, typical luma frequency\r
response maintains 53/145 full amplitude to between 5.0 - 5.5 MHz. This is below the 6.75 MHz native frequency of the\r
MPEG-2 digital signal. Chroma frequency response is one-half that of luma.\r
\end{itemize}\r
\r
The following formats are allowed for H.262/MPEG-2 Part 2 video:\r
\begin{itemize}\r
\item At a display rate of 25 frames per second, interlaced or progressive scan (commonly used in regions with 50 Hz\r
image scanning frequency, compatible with analog 625-line PAL/SECAM):\r
 \begin{adjustwidth}{.5cm}{0cm}\r
 720 {\texttimes} 576 pixels (D-1 resolution, 4:3 fullscreen or 16:9 anamorphic widescreen aspect ratio)\r
 \end{adjustwidth}\r
\item  At a display rate of 29.97 frames per second, interlaced or progressive scan (commonly used in regions with 60 Hz\r
image scanning frequency, compatible with analog 525-line NTSC):\r
 \begin{adjustwidth}{.5cm}{0cm}\r
 720 {\texttimes} 480 pixels (D-1 resolution, 4:3 or 16:9)\r
 \end{adjustwidth}\r
\end{itemize}\r
\r
The official allowed formats for the audio tracks on a DVD-Video are:\r
 \begin{itemize}\r
 \item PCM: 48 kHz or 96 kHz sampling rate, 16 bit or 24 bit Linear PCM, 2 to 6 channels, up to 6,144 kbit/s; N. B.\r
16-bit 48 kHz 8 channel PCM is allowed by the DVD-Video specification but is not well supported by authoring\r
applications or players.\r
 \item  AC-3: 48 kHz sampling rate, 1 to 5.1 (6) channels, up to 448 kbit/s.\r
 \item  MP2: 48 kHz sampling rate, 1 to 7.1 channels, up to 912 kbit/s.\r
 \item  DTS: 48 kHz or 96 kHz sampling rate; channel layouts = 2.0, 2.1, 5.0, 5.1, 6.1; bitrates for 2.0  and 2.1 =\r
377.25 and 503.25 kbit/s, bitrates for 5.x and 6.1 = 754.5 and 1509.75 kbit/s.\r
\item File system:\r
\begin{itemize}[noitemsep]\r
\item Almost all DVD-Video discs use the UDF bridge format, which is a combination of the DVD MicroUDF (a subset of UDF 1.02) and ISO 9660 file systems.\r
\item  The UDF bridge format provides backwards compatibility for operating systems that\r
support only ISO 9660. \r
\item Most DVD players read the UDF filesystem from a DVD-Video disc and ignore the ISO9660 filesystem.  \r
\end{itemize}\r
\end{itemize}\r
\r
\subsection{\textbf{HDV (2003)}}%\r
\label{sub:HDV2003}\r
\r
\begin{itemize}[noitemsep]\r
\item HDV was a successor format to DV with an updated video codec, and used the same MiniDV cassette format, optional\r
specifically for HDV recording on tape with reduced drop-out rate.\r
\item Some manufacturers offered on (larger) camera hard disk recording units capable of recording HDV both onto tape\r
and/or onto file-based media via FireWire connection. \r
\item HDV camcorders can typically switch between HDV/MP2 and SD-DV/PCM recording modes.\r
\item HDV 1080i with horizontal resolution 1440 is twice the 720 resolution of DV and DVD, and the perceived\r
sharpness with HDV is much higher when scaled up to full HD (TV) resolution.\r

\subsection{\textbf{AVCHD (2006-current)}}%\r
\label{sub:AVCHD}\r
\r
\begin{itemize}\r
\item AVCHD stands for \textit{Advanced Video Coding High Definition}, in particular, \textit{MPEG-4 Part 10:\r
AVC/H.264}. The intent of the H.264/AVC project was to create a standard capable of providing good video quality at\r
substantially lower bit rates than previous standards (i.e., half or less the bit rate of MPEG-2, H.263, or MPEG-4 Part\r
2). \\ \r
\item AVCHD is a file based format for digital camcorders to record and playback 1080i and 720p HD-video onto certain\r
random access media. Memory cards, thumb drives, and HDDs use the FAT file system. This highly compressed video allows for\r
recording long videos in high definition.\\\r
\item AVCHD was originally a simplified version of the Blu-ray standard to enable DVD and BD-based camcorders.\r
Recordable optical discs use UDF or ISO9660 derived from the Blu-ray disc specification. For example, it utilizes a\r
legacy 8.3 file naming system while Blu-ray disc uses long filenames. \\\r
\item MTS file extension changes to M2TS when MTS recorded data is transferred to the computer for storing the video in\r
a Blu-ray disc. \\\r
\item Playback is possible on an AVCHD-compatible Blu-ray Disc player/recorder, DVD player/recorder, or PlayStation 3, \r
the 8 cm DVDs (discs recorded in AVCHD) you have recorded or DVDs (discs recorded in AVCHD) and Blu-ray Discs created\r
by importing videos to a PC or Blu-ray Disc player. \\\r
\item Today AVCHD is the most popular camcorder format for consumers and prosumers, and is also available as AVCHD\r
Progressive/PCM models for professional use.\\\r
\item AVCHD supports both \textit{AVCHD-SD Standard Definition} and \textit{AVCHD 1080i High Definition} interlaced\r
video, while AVCHD 1080i is available with most AVCHD camcorders. AVCHD supports 720-line progressive recording mode at\r
frame rates of 24 and 60 frames/s for 60 Hz models and 50 frames/s for 50 Hz models.\\\r
\item Also, 3D (MVC format) and 1080/60p(1080/50p) video formats were added as an extension to the AVCHD format to\r
create the \textit{AVCHD Ver. 2.0, 2011} (AVCHD 3D, AVCHD Progressive) format. Compatibility in AVCHD Ver. 2.0 format compliant devices is secured by being standardized as the AVCHD format.\\\r

\label{sub:Blu-ray}\r
\r
All standard DVDs will play on existing Blu-ray players, making the switch to Blu-ray much easier than the switch\r
from VHS to DVD. Ultra HD Blu-ray is the latest version available, supporting 4K resolution content. Historically,\r
Blu-ray Disc allows video with a color (bit) depth of 8-bits per color YCbCr with 4:2:0 chroma subsampling (colors\r
compressed to 25\% of uncompressed), which means 256 possible values for red, green and blue; 16.7 million colors in\r
total. Ultra-HD Blu Ray is 10-bit 4:2:0 to reduce color banding, giving 1024 values for RGB, 1.0 billion colors in\r
total, or 64x more than 8-bit.\r

\chapter{How to digitize and capture analog video to digital SD video format with A/D video conversion}%\r
\label{cha:how_to}\r
\r
\section{Methods and workflow}%\r
\label{sec:methods}\r
\r
There are a number of ways to get analog source recorded video digitized and captured into the computer. \r
\begin{itemize}\r
\item One way is to use the passthrough feature of an available miniDV camcorder or the digital output of a Sony Digital 8\r
camcorder to convert the Hi8 source to DV, which is then sent via firewire to the computer.\r
\item Another alternative might be a Linux supported external capture card to USB3 (often MPEG-4), or find a higher-end\r
internal PCIe analog video capture card to store uncompressed, 422 or DV video. \r
\item A third way is to use a standalone analog to digital A/D converter and capture device. This might be to DV HDD recorder\r
or optional to a high-end analog/SDI and a SSD 422 codec (i.e ProRes) recorder.\r
\end{itemize}\r
\hspace*{.9cm} An example workflow and setup for this third way:\r

\r
\begin{itemize}\r
\item A fourth, interesting way as discussed on the CinGG mailing list (yet to be tested), is to combine a HDMI-USB3 capture dongle with an Analog Video to Digital HDMI miniConverter (ADC). The analog video player output (via TBC) connects to the actual input connectors (S-video/RCA or possibly Component) of the adapter.  Reference the following from/to: \\\r

\label{sec:equipment}\r
\r
\begin{itemize}\r
\item The first required is a tape player device (VCR deck or camcorder) to playback the analog video tape cassette formats,\r
either VHS/ SVHS, VHS-C/ SVHS-C or Video8/ Hi8. Use a video head cleaning tape before use. Wind and rewind the tape\r
cassette before playback in Edit mode "ON" to minimize picture deterioration. \\\r
\item A second recommended device for all capture methods is a Time Base Corrector (TBC).  Connected to the analog output of\r
a VCR, a good TBC can make wonder and remove most or all of the flagging, shaky pictures, wavy lines, and other time\r
base problems from a videotape, to get a clearer and more steady picture. The best is a standalone, fullframe\r
high-resolution TBC of broadcast quality; minimum is a line-based TBC built in high-end VCR decks. \\\r
\item A third, optional feature before digitizing is a noise filter to reduce/soften noise and grain (snow) from bad VHS tape\r
recordings, or also when video that is over-processed using sharpness controls and enhancers. Noise filter adjustment\r
may be part of the TBC setup and preview, or fixed built in the playback VCR.  Optional a standalone Video\r
corrector/processor if available can be used, where also optional brightness, contrast and color saturation/correction\r
can be adjusted.\r

\chapter{\textbf{DV files converted to Blu-ray compliant MPEG-2/LPCM and authored to SD BD-Video}}%\r
\label{cha:dv_files}\r
\r
\textbf{Step 1}\r
\r
\begin{itemize}\r
\item Prepare a 40 GB continuously DV input file by joining and concatenating the actual dv clips in order. Each\r
digitized Hi8 video tape was automatically split and recorded as a numbered series of 2.0 GB dv files each. \\\r
\item Naming convention used, for example, for Tape \#1 with clips in order: \texttt{dv01, dv01-01, dv01\_02, dv01\_03},\r
etc. For the full example at the end of this article, the concatenated \texttt{DV41\_02+DV42+DV43\_02} contains the clips from on\r
 \texttt{dv41\_02+all dv42} up to and including \texttt{dv43\_02}.\r
\end{itemize}\r
\r
\textbf{Step 2}\r
\r
\begin{itemize}\r
\item Encode DV to MPEG-2 video and "re-encode" uncompressed PCM to Blu-ray PCM audio and\r
remux to interlaced SD-BD-video.mts: \r
\begin{lstlisting}[style=sh]\r
ffmpeg -i DV41_02+DV42+DV43_02.dv -c:v mpeg2video -refs 1 -bf 2 -b:v 25M -maxrate 25M -minrate 25M -bufsize 28M -muxrate 28M -dc 10 -c:a pcm_bluray -mpegts_m2ts_mode 1 -flags +ilme+ildct SD-BD_DV41_02+DV42+DV43_02.mts\r
\end{lstlisting}\r
\end{itemize}\r
\r
\textbf{Step 3}\r
\r
\begin{itemize}\r
\item Run \textbf{tsMuxer} (screenshot of tsMuxer usage is displayed at the end of this article). The following\r
parameters are shown for tsMuxer\_SD\_M2TS: \\\r
\newline\hspace*{.5cm} Input file: \texttt{SD-BD\_DV41\_02+DV42+DV43\_02.mts} \r
\newline\hspace*{.5cm} Tracs:\hspace*{.63cm}\ MPEG-2 video stream and LPCM audio stream \r
\newline\hspace*{.5cm} Output:\hspace*{.37cm} \texttt{SD-BD\_DV41\_02+DV42+DV43\_02.iso}\r
\end{itemize}\r
\r
\textbf{Step 4}\r
\begin{itemize}\r
\item Burn the iso SD-BD-Video image with \textbf{xorriso} on a BD-R DL 50 GB disc:\r
\begin{lstlisting}[style=sh]\r
xorriso -as cdrecord -v -sao dev=/dev/sr1 SD-BD_DV41_02+DV42+DV43_02.iso\r
\end{lstlisting}\r
\end{itemize}\r
\r
\chapter{\textbf{HDV.m2t files converted and authored to HD BD-Video}}%\r
\label{cha:hdvm2t}\r
\r
\textbf{Step 1}\r
\begin{itemize}\r
\item Prepare the source HDV.m2t file using hdv clips as for DV above.\r
\end{itemize}\r
\r
\textbf{Step 2}\r
\begin{itemize}\r
\item Copying the mpeg2 video, re-encoding MP2 audio to Blu-ray LPCM. If using an ffmpeg version lower than 5.1,\r
substitute ac3 for pcm\_bluray and add -b:a 384 to override lower default. \r
\r
\begin{lstlisting}[style=sh]\r
ffmpeg -i HDV.m2t -c:v copy -c:a pcm_bluray -mpegts_m2ts_mode 1 HDV.mts \r
\end{lstlisting}\r
\end{itemize}\r
\r
\textbf{Step 3}\r
\begin{itemize}\r
\item Run \textbf{tsMuxer} (screenshot of tsMuxer usage is displayed at the end of this article). \r
\newline\hspace*{.5cm} Input file: \texttt{HD-BD\_HDV.mts} \r
\newline\hspace*{.5cm} Tracs: \hspace*{.5cm} MPEG-2 video stream and LPCM audio stream \r
\newline\hspace*{.5cm} Output: \hspace*{.25cm} \texttt{HD-BD\_HDV.iso}\r
\end{itemize}\r
\r
\textbf{Step 4}\r
\begin{itemize}\r
\item Burn the iso HD-BD-Video image with \textbf{xorriso} on a BD-R DL 50 GB disc:\r
\begin{lstlisting}[style=sh]\r
 xorriso -as cdrecord -v -sao dev=/dev/sr1 HD-BD_HDV.iso\r
