Video/Sound Converter



Media - Video/Sound Converter    or
 Sound - Video/Sound Converter



Video or sound files can be converted here.
The output format is optimized in each case for use in the liveSHOWsoftware.
For example, more KeyFrames are generated than with most conversion programs.

Attention: Converting a video puts a heavy load on the processor, please do not convert a video while a show is running.


Button_SoundFrameLoad
Opens a video or sound file. Many standard formats are supported.

If a video file was opened, the beginning , the middle and the end of the video will be displayed as an image:


If a sound file was opened, a speaker icon is displayed:




Video Settings

Image size:
under Width you can specify a new width in pixels.
Under Height you can specify a new height in pixels.
Pressing the Enter key will apply the changes.
The ratio of width and height will be adjusted according to the original.
The maximum image size is either the original size of the loaded video or the 4K resolution (3840 x 2160).

You should try to choose the smallest possible image size that is still sufficient for display. The larger an image is, the more processing power is consumed. Try to adapt the image size to your output medium.
On low performance computers no 4K (3840 x 2160) video will run without hanging!!! Ideally, the image size should be HD (1920 x 1080) or smaller.
Note: The aspect ratio is taken from the original. If you want to display the video distorted, you can set this in the object settings of the media object.

Note: It can be that a video is played smoothly by other software (e.g. VLC player), but in the liveSHOWsoftware the video hangs or jerks.
This is because the liveSHOWsoftware does not just play the video, but has to overlay and transform it with other media. Reducing the picture size leads haüfig to the goal.

Video Image Quality:

  • Standard (fast)
    The default ffmpeg converter is used
    the conversion is fast
    the image quality may suffer
  • High Quality (slow)
    The VP9 converter is used
    the conversion can take a long time depending on the processor speed (possibly several times the length of the film)
    the image quality is high

Display Aspect ratio:
The display of a video does not have to be in the saved width and height. The video file can specify how the video's images should be distorted during playback.
You can specify a different aspect ratio (width / height). The images of the video will be saved in the specified width and height, but the display when playing the video will be distorted.
   1.0 = the representation corresponds to the saved width and height.
< 1.0 = the width of the images is compressed during playback.
> 1.0 = the images are compressed in height during playback

Frame rate:
The frame rate specifies how many frames per second are played. Ideal here are 25 or 30 fps (frames per second).
A higher frame rate requires correspondingly more computing power and is not enabled here.

Some videos distort the image in the display, this is indicated by the 'Aspect ratio'.
The individual frames are saved as specified for width and height, but the image is distorted in the display.
This setting is taken from the original and is not changed.




Sound Settings



Channels:
Here you can determine the number of audio channels. For multi-channel files (5.1 or 8.1 sound), the list of selectable audio channels is extended.
For example, a stereo signal can be generated from a 5.1 sourround sound. However, it makes no sense to create a 5.1 sourround file from a stereo file. You can set this in the sound lines settings of a sound object.

If 0(-) is selected for a video file, the sound is removed from the video.

Converts the video file with the changed parameters. A file selection window opens where you can specify the output file.

A video is always encoded as mp4 video here (Video codec: H264 or VP9).
Every 50-60 frames a KeyFrame (GOP) is created.
Note: A KeyFrame (GOP) always contains the complete image, the following frames only store the changes to the previous image.
Normally a KeyFrame is generated after approx. 300 frames, the liveSHOWsoftware increases the number of KexFrames. The more KeyFrames there are, the faster you can jump to a certain position.

Converts a sound file or extracts the sound from a video file. A file selection window opens where the output file can be specified.

A sound is encoded as a wav file.
The liveSHOWsoftware currently uses the following audio format: PCM 44100 Hz, 16bit signed, little endian (CD quality).


Conversion
status

During the conversion, the current state of the conversion is displayed.
Unfortunately, since an extra process is used during the conversion, no progress bar can be displayed.
Note: Converting a video can take a lot of time!
Cancels the conversion. The started output file is deleted.
