Convert anything to 3GP

The API for converting any file to 3GP.

Here you can see all available conversion options which you can use within the "options" section of conversions (see the example JSON below the table).

Here you can see all available conversion options which you can use within the "options" section of conversions (see the example JSON on the right).

Option Name	Description
allow_multiple_outputs Type: boolean Default: False	If the conversion produces more than one output file, by default all of them are compressed in just one file. Set this option to true if you want a download link for each file.
allow_multiple_outputs_threshold Type: integer Minimum: 2 Maximum: 400	Sets the threshold for the number of output files during conversion. This option is considered only when `allow_multiple_outputs` is set to true. If the generated output files exceed this threshold, they are compressed into one file. Conversely, if the threshold is not met, each output file remains uncompressed.
aspect_ratio Type: string Pattern: ^\d{1,6}:\d{1,6}$	Specify the aspect ratio of the video e.g. 16:9.
audio_codec Type: string Enum: amr-nb aac copy	Sets the audio codec
audio_frequency Type: integer Enum: 8000 11025 16000 22050 24000 32000 44100 48000 96000	Audio frequency in Hz.
channel Type: string Enum: stereo mono	Audio channels.
codec Type: string Enum: h.263 h.264 mpeg4 copy	Sets the video codec
crf Type: integer Minimum: False Maximum: 51	The Constant Rate Factor (CRF) allows the encoder to attempt to achieve a certain output quality for the whole file when output file size is of less importance. Lower values result in better quality at the expense of a higher file size. This option will be ignored if video_bitrate is set.
default_still_frame_duration Type: number Minimum: 0.02867 Maximum: 1800	Defines the duration in seconds of a still frame. E.g. when converting from images or documents.
deinterlace Type: boolean Default: False	Deinterlace the video
download_password Type: string Pattern: ^[ -~]{0,1000}$ Example: secret_password	A password to protect the download. To download the file send the password in the x-oc-download-password header or set a cookie named x-oc-download-password. The value contains a comma separated list of passwords.
end Type: string Pattern: ^\d\d:\d\d:\d\d$	Sets the end point of the part of the video you want to keep. The format is HH:MM:SS. HH = hour, MM = minutes, SS = seconds. Example 00:05:35
format Type: string Enum: sqcif qcif cif 4cif 16cif
framerate Type: number Minimum: True Maximum: 120	Specifies the video frames per second
merge Type: boolean	Allows to merge the input files to a single video
mirror Type: string Enum: none horizontal vertical	Mirror/flip your video
normalize Type: boolean Default: False	Normalize the audio volume.
output_filename Type: string Pattern: ^[\w\W]{0,255}$ Example: my_base_filename_without_extension	The desired file name of the converted file WITHOUT the file extension.
overlays Type: array Additionalproperties: False Input_id: string ^[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$ 1 Define the input_id of the file you want to specify as an overlay. Valid files are videos and images Position_x: integer -100000 100000 The position of the overlay on the x-axis Position_y: integer -100000 100000 The position of the overlay on the y-axis Origin: string Top-left: Top-right: Bottom-left: Bottom-right: Center: Specify the origin for the positioning of the overlay. Default is top-left Width: integer 0 100000 The width of the overlay Height: integer 0 100000 The height of the overlay Opacity: string ^[0,1]$\|^0\.\d{1,2}$ Define the opacity of the overlay where 0 is invisible and 1 is full opacity
preset Type: string Pattern: ^[\w\W]{1,255}$	Predefined options
remove_audio Type: boolean Default: False	Disable the audio track
start Type: string Pattern: ^\d\d:\d\d:\d\d$	Sets the start point of the part of the video you want to keep. The format is HH:MM:SS. HH = hour, MM = minutes, SS = seconds. Example 00:02:23
video_bitrate Type: integer Minimum: True Maximum: 100000	Specifies the bitrate in kbps
