TnA - Tanoshimi no Autohardsubber

Simple, yet almost automatic, autohardsubber from Tanoshimi no Sekai Fansub, written in C# .NET 4.8.

THIS PROJECT IS DEAD. I'VE NO INTENTION TO GO ON DEVELOPING.

Building

This solution requires a C# compiler for Windows.
For example, Visual Studio Community 2019, even without registration.
No need to use Professional or Enterprise edition, but you can.

Requirements for building

• FFmpeg by Gyan x64 release full static for Windows (automatically downloaded)
• SevenZipSharp (no need to install 7z)
• 7z.dll 19.00 x64 directly extracted from x64 setup
• MediaInfoNet x64 (no need to install MediaInfo)
• FFmpeg Output Wrapper DLL x64 (for encoding progress)
• mkvmerge.exe from MKVtoolnix x64 for Windows (for MKV remux)
• SCXviD x64 standalone for Windows for keyframes generation.

Features

• Only italian language, for now.
• No administrator rights required.
• Can be placed in a netfolder and used with multiple PCs (not recommended).
• Supported file formats:
  • MKV (this is the only supported format for autohardsubbing)
  • MP4
  • M2TS (only for MKV remux)
  • TS (only for MKV remux)
  • AVI
  • MOV
  • RMVB (not tested)
  • OGM (not tested)
  • FLV (not tested)
  • VOB
  • MPG/MPEG
  • 3GP (not tested)
  • M4V (not tested)
• Automatic extraction of fonts and subtitle track from MKV files (no need to install fonts).
• Built-in updater.
• Autodeinterlacing when needed with YADIF, mode=0 for spatial check without bobbing (only if TFF or BFF are detected, otherwise disabled).
  This is not the best way for deinterlacing, but it's very fast and simple to use.
• Instead of xyVSfilter (not included in FFmpeg), it uses LIBASS for Advanced Substation Alpha subtitles and generally works well.
• Format selection when adding an entire folder.
• Clipboard monitoring, similar to JDownloader.
  By activating this, you can just copy files and folder from File Explorer and they will be automatically added, following the formats choices.
• Settings save in .ini file.
• Automatic removing of source file after a correct conversion (this feature has to be tested, because files seem removed, but they're not). (Removed because not working).
• Pause/resume conversion.
• SendTo link in Windows SendTo menù can be created or removed.
• Possibility to choose one action after conversion of all listed files.
• Can be restored to initial settings.
• Audio track copying instead of re-encoding if destination audio is equal to source's.
• Remuxing files to MKV (with mkvmerge, ignoring all other settings) and to MP4 files.
  MP4 remux only supports:
  • H.264/H.265/XviD/DivX/MPEG 1-2-4 video streams
  • AAC/AC-3/MP3/ALAC audio streams
  • No subtitles of any kind, except TimedText (very rare and only used for 3GP).
  • Any other stream not listed above will be re-encoded according to the other parameters.
• All videos will be resized if selected resolution of destination is lower than source's, considering aspect ratio. It'll never do any upscale.
  For example, a video source with resolution 1280x720 will never be upscaled to 1600x900, even selecting 900p for resolution.
  So, don't try to.
• Because there are videos with odd resolution, such as 1555x813 or one between width and height, because every compatibility profile is designed to reach standard encoding, this application will recalculate the destination resolution.
  For example, if width is odd, it will be lowered by 1, the same for height.
• While aspect ratio is greater than or equal to 1,333 (4:3), width will be used for resizing.
  Instead, height will be used.
• Keyframes generation in a txt file.

Hardware requirements

Minimum

• OS: Windows 7/8/8.1/10 (x64 only).
• CPU: Intel Core 2 Quad, 2,00 GHz x 4.
• RAM: 4 GB DDR2 (better have DDR3).
• GPU: any.
• SSD/HDD: HDD, better yet with SSD.

Recommended

• OS: Windows 7/8/8.1/10 (x64 only).
• CPU: the faster, the better.
• RAM: 8 GB DDR4.
• GPU: any.
• SSD/HDD: HDD, better yet with SSD.

Actually, any hardware will be fine (excepted RAM) because it's just a matter of how much time is needed to process video files. Obviously, process will be slow with slow PCs. For example, a video 1080p with 23,976 fps, duration of 24 mins, encoded at below-medium quality, reaches 10-12 fps during conversion: PC is slow or not suitable for video encoding, but time needed is still acceptable. Keep in mind that deinterlacing slows down encoding speed.

• Case AR lower than 1,333 (4:3): heigth is used.

Possible values are:

• 900p
• 720p
• 576p
• 480p (actually it's 486p)
• 396p
• 360p
• 288p

Quality

Quality is the parameter that determines the final quality of destination file.
Possible values are:

• Altissima (Highest)
  • Mostly useless.
  • Very slow.
  • Very high bitrate.
  • Very large filesize.
• Alta (High)
  • Useful to keep high quality.
  • Not as slow as Highest quality but slower than Above medium quality.
  • Large filesize.
• Medio-alta (Above medium)
  • Good quality.
  • Medium filesize (sometimes large, but it rarely happens).
  • Slower than Medium quality but faster than High.
• Media (Medium)
  • Good compromise between quality and filesize.
  • Medium speed.
  • Normal filesize.
• Medio-bassa (Below medium)
  • Resonable quality.
  • Fast.
  • Quite small filesize.
  • Suitable for streaming.
• Bassa (Low)
  • Low quality.
  • Small filesize.
  • Suitable for streaming.
  • Faster.
• Bassissima (Lowest)
  • Very low quality.
  • Very small filesize.
  • Suitable for streaming, but no, do not use this preset for streaming.
  • Very fast.
• Bozza (Draft)
  • THIS PRESET IS FOR TESTING ONLY.
  • Useful to make conversion tests.
  • The fastest.
  • Very bad quality.
  • Smallest filesize

Audio bitrate is determined using bitrate for stereo and multiplied by audio channel number, then divided by 2 (excepted for AC-3, not divided by 2).

Subtitle modes

• Hardsub
  1. Demuxes all fonts inside MKV, if any.
  2. Scans for forced subtitle track, if any. Otherwise, default subtitle track, if any. If not found default or forced subtitles, it picks the first track. If there's no subtitles, it just skips demux and jumps to encode process.
• Softsub
  • Copies all fonts and subtitle tracks inside MKV file and just re-encode video and audio, according to compatibility and quality presets.
  • It forces MKV container for destination file.
• No sottotitoli (No subtitles)
  • Ignores all subtitle tracks and fonts

Hardsub mode will choose only one subtitle track, never two or more.

Usage

• Drag&drop files and folders, use buttons or paste files and folders from system clipboard.
• Choose one among compatibility profiles, resolutions (height), quality profiles, subtitle modes.
• Click on Play button and wait. Destination files will be in the same folder of source files, never overwritten.

Hints

• You can convert the same file twice or more, just be sure to change compatibility, quality or resolution.
• Filelist is a Datagridview, similar to Excel or Calc. Clicking on the row header will select all lines in the grid.
• Selection can be done using Shift or CTRL key, too.
