Introduction

HandySaw is intended to facilitate the job for people who work with nonlinear editing (NLE) software.

To accelerate the digitalization process the source material is usually captured as one or several large pieces, operate with such source files can be rather difficult. Instead of one long clip it is desirable to have a set of short clips, each one containing one single "scene" (e.g. from the start to the end of  recording).

This is the task that can be accomplished by HandySaw DS.

HandySaw DS is a Powerful Automatic Optical Video Scene Detection Tool.

 


 

Main Features

Video scenes detection

Main window of HandySaw DS- video scene detection software. Click to see large pictureHandySaw DS offers two methods of scenes detection in the videofile:

  1. Optical. The program parses content of the videofile, finds scene changes and divides the initial video into separate scenes. For this analysis only videostream data is used; timecodes or any other information are not required. Of course 100% correct results cannot be guaranteed but, on the average, it is rather high.
    Also thus there is an opportunity to detect very dark and very light frames as a separate scenes.
  2. By the date of shooting. Cameras of DV standard and the standards based on DV (DVCAM, DVCPRO), during the shoot saves time and date of shooting of each frame of video on a tape. Then if video is transferred in a computer via digital FireWire interface this information is saved in the videofile. If HandySaw finds it then search of scenes is fulfilled with usage of these data. In this case accuracy of detection makes 100 % under condition of absence of a spoilage in initial video.

Supports many video formats

Due to use MS DirectShow API HandySaw DS is capable to process the big number of formats of videofiles - AVI, MPEG, MOV, etc. Basically it can process any videofile for which there are corresponding DirectShow filters.

Works in YUV or RGB color space

Scene detector can works in YUV or RGB color space. The user can choose.

Many formats of presentation of result of splitting

HandySaw DS offers a wide range of variants of representation of the information of splitting into scenes:

  • Copying of each scene in a separate file using internal routines
  • Copying each scene in a separate file by ffmpeg software
  • Copying each scene in a separate file by VirtualDub software
  • Final Cut XML
  • Libraries in format PLB and PSQ for Adobe Premiere
  • EDL file for Sony Vegas
  • CMX3600 EDL
  • EDL file for EDUIS
  • Edition list in the HTML format
  • Besides this it is possible to create new type of result, having written a plug-in for HandySaw...

Support of plug-ins of result generation

HandySaw DS supports plug-ins of generation of the result, written on script languages (for example JavaScript, VBScript). If you wish to receive result of splitting in a special kind, you can create a new plug-in which will meet your requirements.
In corresponding section of the help there is a full information for the developer of plug-ins.

The powerful tool for manual editing - Manual Trimmer

In addition to automatic partitioning there is Manual Trimmer tool which allows you:

  • To check up a correctness of automatic partitioning on scenes.
  • To delete unnecessary scenes.
  • Precisely to cut off any scene.
  • To splice two scenes.
  • To divide a scene in the defined place on two.
  • To give names to scenes.
  • To enter comments to scenes.
  • To place the unnumbered markers which will be accessible in Adobe Premiere.
  • At any moment to save the current information in HSQ the file.
  • To convenience of the user mechanism Hold/Fetch and 99 levels Undo/Redo are accessible.

Thus, automatic partitioning on scenes in a combination with Manual Trimmer allows fast and convenient to prepare the initial material for editing in the videoeditor

Copying of each scene into separate WMV file without recompression

If source video - a WMV file, HandySaw DS can save each found scene into separate WMV file without recompression.

Copying of each scene into separate AVI file with recompression

You can save each scene in separate AVI file and at the same time video and audio can be recompressed by the codecs chosen by you.

Copying each scene into separate MOV file without recompression

You can save each scene from QuickTime source to separate MOV file without recompression.

Copying each scene into separate file of the same format with or without recompression using FFmpeg software

HandySaw can copy each scene in separate file of the same format without recompression using FFmpeg software. Also it can recompress media to another format. It is possible for almost any video file format.

Batch mode processing

You can set the list of files for processing and HandySaw DS will process all of them by turns.

Support of a command line interface

The powerful command line interface allows to organize any scenario of use of HandySaw DS.

Creation and printing of reports on splitting

You can create the report on splitting a videofile, print out it on the printer or save in sequence of BMP files by means of tool Clip Sheet.

Possibility of easy localization of the program

Because all the significant symbolical strings, used in the interface of the program, are in a separate text file, to translate the program to other language is rather simply. Initially there are an English and Russian language packages.

 


 

Output data format

HandySaw DS can generate these types of result:

  • Split (separate files) - in this case HandySaw DS copies each retrieved scene in a separate media file. Depending of settings copying may be with or without media transcoding. If Create Subfolder item is marked, a subdirectory with name "FIlename.Scenes" will be created and all scenes will be saved in it. If the source video and result are located on one disk, resulting audio files will be saved in the audio drive you indicated (in the Preferences) in the appropriate directory. If source and output disks are different, audio is saved near to video.
  • Simple List - the result is a text file, in which the frame numbers of the beginning and end of the scenes are listed. Each scene is in a separate line.
  • Compatible PLB - HandySaw DS creates an Adobe Premiere Library (.PLB) file, where to each retrieved scene there corresponds one clip referring to the initial videofile. In addition there is a clip containing all initial video. This clip may contain the unnumbered markers, marking each scene start. In Adobe Premiere (further AP) it is possible for version 5 to simply open the .PLB file and import it into the project. In AP 6+ you have to import the .PLB file into an existing project! The file format is compatible with AP as much as possible. For AP 6+ use PSQ 6 instead.
  • Usage PLB - with this option a PLB file is created also, but its format slightly differs from previous. It has some advantages and disadvantages.
    On the one hand — in the project window in the "Usage" column there is a correct value of how many times this clip was located on timeline. In "Compatible PLB" all this statistics is displayed only for last, complete clip referring to all video.
    On the other hand — Project Trimming function do not work correctly. It is impossible to use it. For AP 6+ use PSQ 6 instead.
  • AP 5 PSQ - PSQ file - Adobe Premiere Sequence in Adobe Premiere 5 format.
  • AP 6 PSQ - PSQ file - Adobe Premiere Sequence in Adobe Premiere 6 format, can contain comments of the user. PSQ 6 files can be imported in Adobe Premiere Pro.
  • Vegas EDL - text file in EDL format which can be opened in Sony Vegas program.

Further in the list all result generation plug-ins installed in your system are listed. In standard package there are:

  • CMX3600 EDL.js - file of EDL CMX3600 format is created. It is compatible with Adobe Premiere Pro
  • Edius EDL.js - EDL format file compatible with Canopus Edius is created
  • Final Cut XML.js - creates FinalCut XML file that describes sequence with input file splitted on clips by scenes. It also contains scene comments and markers. Many editing systems now supports Final Cut XML format importing.
  • HTML EDL.js - the edition list in the HTML format is created
  • Split by VirtualDub.js - the script .SYL for VirtualDub is created. During execution of created script VirtualDub copies each scene of source AVI file in separate AVI file without recompression.
