Do you search for the SDK that will help you to develop Windows based application for fast and easy video editing?
You are on the right way and we have the good news: trying to offer something outstanding for you, we have finally released the SolveigMM Video Editing SDK 5 for Windows.
Video Editing SDK for Windows comprises a set of tools capable of working without re-encoding and with support of all popular multimedia formats and codecs. The Video Editing SDK is a great choice for developers who work with video and audio related software, smart video editing applications for desktop or cloud.
The SDK is based on the SolveigMM Smart Rendering Technology that makes it possible for anyone to create fast and lossless video/audio editing applications.
A Video Editing Engine object is the basic part of the SDK. It is responsible for performing a number of editing operations in the smart mode. All these operations are available also via smm_batchsplit utility. This is a command-line utility to process tasks represented by batch files (*.xtl). You’ll find the examples of code below at this page.
The online documentation on the Video Editing SDK for Windows is available for you here.
Also if you are interested in HTML5 Video Editor API, you can find it at this page.
We have prepared the list of supported operations that could be performed based on the SDK by means of the smm_batchsplit.
Trimming
As the name of this operation says, it is responsible for trimming, cutting out and saving any number of segments from the loaded input files. The operation performs with a frame accuracy and lossless merging of the segments marked for saving.
The trimming is fulfilled by using the following XTL code:
At the end of the task execution, the “sample_mp4_0001.mp4” file will be created out of the source file “test_file.mp4”. The resulting file will contain the two segments from the source file – seconds 1-6 and 7-12.
Watch the video showing the result of this operation.
Adding of effects/transitions to the output file
Need to enhance your own application with the ability of adding transitions or applying different effects? The Video Editing SDK lets you do this as easy as pie with our unique Engine.
Works currently for MP4 AVC and MXF XAVC video files.
– fade-in / fade-out,
– dissolve
Dissolve
The dissolve transition between 2 videos is described with this sample. The transition lasts for 3 seconds.
See XTL project below that applies this type of transition:
The output file structure and duration is shown by the first track of the XTL. This track includes all files that will create the output file.
The “effect” tag is to describe the timings for each of the dissolves and the number of dissolves should be the same as the number of “effect” tags.
The “fade out” part is described by each “effect” tag, on the first file from the couple of files that will be dissolved.
Supplementary track is necessary for each second file from the affected couple. These tracks must contain the following info:
Number and type of the stream where transition is going to be. Please be aware that only one type of stream should be selected.
“effect” tag, that denotes the “fade in” on the second file from the couple
“transition” tag. It shows that the actual track will be operated according to that tag and included to the output file.
The file “transition_dissolve.mp4” will be built as the result of this XTL execution. It has two equal videos and one dissolve transition between them. This transition starts from the 12th second and lasts for 3 seconds.
Here is the output result of it:
Fade-in and Fade-out
The sample demonstrates the “fade in” and “fade out” effects on one video. Each effect continues for three seconds.
Please find below the description of the XTL for fade-in and fade-out transitions.
The file “transition_fadein_fadeout.mp4” should be built at the end of processing of this XTL project.
The sample consists of one file, which are represented by the “clip” and two “effect” tags. The first “effect” tag is for the “fade in” and the second tag is for the “fade out”. There are also extra parameters in “param” tags: a background color, a transparency value and variation function. The “fade in” effect is at the beginning of the file and the “fade out” effect is at its end.
Please see the output file here:
Mute audio segments
This feature replaces the specified segments of the media file with silence.
Below you will find the XTL project that allows to mute the audio on the selected segments.
When the processing of this XTL project finishes the “audio_mute.mp4” file will be created. The first and the last five seconds of the output file are silent.
Please see the resulted file here:
Mixing audio from the separate file
This feature is made for mixing or overlaying the audio from M4A, MP3 files or sound from AAC, MP3 or PCM streams from MP4 files to your file. It is also known as a “Voice-over”.
The result of this project is the “audio_mix.mp4” file that includes the input file “test_file.mp4” with the 13 seconds segment of sound mixed from the “voice-over.mp3” file.
See the result here, please:
Adding images to your video
There are several operations with images available by means of the Video Editing SDK:
Overlaying pictures on a video file
If you would like to overlay a picture to your video or add a watermark or a logo, you can do this with SolveigMM Video Editing SDK.
This feature is currently supported for MP4 files with AVC video and MXF files with XAVC video.
The XTL project below represents the description of overlaying images on video file.
As a result of this XTL project processing, the “image_overlay.mp4 file” will be created. The rendered file will contain the SolveigMM logo overlaid at the defined position on the video. The logo start at 2 seconds and displays for ten seconds.
Please see the output file here:
Making the video from images
When you need to combine several pictures to a video, SolveigMM Video Editing SDK is there for you. It provides the functionality to easily make the MP4 (AVC) or MXF (XAVC) video files from a bunch of the PNG or JPG images.
The parameters of compression need to be set either by indicating the reference file or they can also be described directly:
The output video created with this XTL project contains the five images, each of them is shown for a duration of 2 seconds and is encoded with H.264 codec. There are also fade-in effect at the beginning of the video that lasts for 2 seconds and the audio stream in AAC with duration of 10 seconds added to the video file.
Please take a look at the output file for this XTL project:

At the end of this XTL project’s processing, the “transitions_avc_mp4.mp4” file will be created, where you can see the different transitions and effects applied to the file:
“Fade-in” effect on the first file that lasts for 1 second starting at 0 second.
“Dissolve” transition between the first and the second files. The transition lasts for 1 second and starts at the 1 second.
“Fade-out” effect that you can see at the end of the second file. It lasts for 1 second and starts at 2 second.
Overlaying image on the video. The effect starts at 1 second and has the duration of 1 second.
Adding audio tracks separately from the same input files
Mixing sound from the MP3 file. It starts at 0.5 second and has the duration of 2 seconds.
Please note, while rendering the output file with the encoding parameters used in the “test_video_1.mp4” reference file, the transcoding will be applied.

The video below shows the online editing using the HTML5 Video Editor:
Utilities
For cases when it is less handy to compose and run the XTL project to do the specific task, we have included some helpful utilities. They perform certain features and do not need the XTL project for processing.
smm_ts2mp4
This is the utility that allows to convert the entire input MPEG-TS file (that contains AVC or HEVC video and AAC audio) or the segment from it to the MP4 file with AAC audio.
-source – defines the name of the input MPEG-TS file -dest – defines the name of the output MP4 file -starttime and -endtime indicates the start and stop time position of the segment in milliseconds -frameacc – allows the frame accuracy for editing
smm_mp4transc
It is a command-line tool that transcodes an MP4 file with AVC or HEVC video and AAC audio with the codec and container parameters specified by the reference MP4 (AVC video, AAC audio) file.
An example of usage:
-sourcemp4 – defines the name of the input MP4 file -refmp4 – indicates the reference file. Its parameters will be used for encoding -destmp4 – defines the name of the output MP4 file
The picture below shows the parameters of the input video file
