Program to create video files based on simple instructions
Budget: $30 – $250 USD
We are looking for someone to write a program to create video files using simple instructions in an instruction file (a text file).
This program will have NO user interface. This program will only run from the command line, C:\makevideo.exe <instruction-file.txt>.
Here are the instructions that you will need to program:
output_file=c:\videos\123.mp4 (name of the video file to create, with full path)
video_format=mp4 (video format to create, mp4 is the default)
The section instructions are used to describe a section of the video.
A section means something displayed on the screen for a period of time.
section_start
section_text=This is a sentence that can be very long and have <br> to skip a line
section_text_alignment=center (left, right, center=default)
section_text_voice=female (a female or male voice reads the text, or specify the name of a voice "john","mary" etc.)
section_duration=30 (the section stays displayed for 30 seconds. This is the time duration that the text remains visible in seconds before moving to the next section. If it takes 10 seconds to read the text, then the remaining 20 seconds are silent. When duration is 0 or is not specified in the instruction file then the duration becomes the duration of the voice reading the text, so if reading the text takes 4 seconds, then the section ends in 4 seconds. If reading the text takes 2 seconds and the duration is set to 10 seconds, the remaining 8 seconds are silent, meaning that the image or text on the screen remains for 8 seconds in silence.)
section_background_color=red (sets the background to a color, specified by a name of a standard color)
section_background_image=image.jpg (it displays the image on the screen as the background, behind the text)
section_music=song.mp3 (plays a song for the duration of the section, which is based on the length of section_duration or the time it takes to read the text. If a text is being read, the music will also play if a music file is specified. If the music file is shorter than the duration or the time it takes to read the text, then it simply ends when it is at the end. It does not loop.)
section_text_font=Arial (specifies a font for the text. Arial is the default)
section_text_font_size=12 (specifies a font size for the text. 12 is the default)
section_text_font_color=black (specifies a font color for the text. Black is the default)
section_end (specifies the end of instructions for a section)
When section_start appears again in the instruction file, it means the start of the next section of the video.
There can be an unlimited number of sections in the instruction file.
video_insert=video.mp4 (this inserts an existing video at this point, into the video being created)
EXAMPLE (instruction-file.txt):
output_file=c:\videos\123.mp4
video_format=mp4
section_start
section_text=Hello<br>How are you?
section_text_voice=female
section_background_color=yellow
video_insert=video1.mp4
section_start
section_text=Today is Sunday
section_text_voice=male
section_background_image=image.jpg
section_start
section_text=This text will appear for 1 minute
section_text_voice=male
section_duration=60
video_insert=video2.mp4
section_start
section_text=This RED text is larger than the standard size<br>and uses another font
section_text_voice=male
section_text_font=Calibra
section_text_font_size=14
section_text_font_color=red
video_insert=video3.mp4
END OF EXAMPLE.
