2.Quickstart Example:
Use this Python snippet to transcode your first video:
from videodb import TranscodeMode, VideoConfig, AudioConfig, ResizeMode
job_id = conn.transcode(
source="https://example.com/sample.mp4",
callback_url="https://example.com/webhooks/videodb",
mode=TranscodeMode.lightning, # or TranscodeMode.economy
video_config=VideoConfig(
resolution=360,
framerate=24,
resize_mode=ResizeMode.crop # crop | fit | pad
),
audio_config=AudioConfig(
mute=True # or False
)
)
print(f"Job queued ➜ {job_id}")
