Creating circular video notes from user uploads in Telegram bot (Aiogram 3.11)

How can I transform a regular video into a circular video note in my Telegram bot?

I’m working on a bot using Aiogram 3.11 and I want to add a feature where users can send a video, and the bot will convert it into one of those round video notes. Then it should send the circular video back to the chat. I’m not sure how to do the conversion part.

Here’s what I’ve got so far:

@router.message(Command("make_round"))
async def create_circular_video(message: Message):
    # Need help with video processing here
    await message.reply_video_note(video_note="processed_video_id")

The bot can receive the video, but I’m stuck on how to actually turn it into a circular format. Any ideas on how to handle the video processing step? Thanks!

To create circular video notes, you’ll need to combine ffmpeg for video processing with your Aiogram bot. Here’s a high-level approach:

  1. Save the received video to a temporary file.
  2. Use ffmpeg to process the video (crop, scale, and format as needed).
  3. Send the processed video as a video note.

You’ll need to install ffmpeg on your system and use subprocess to call it from Python. The exact ffmpeg command may need adjustments based on your specific requirements and input videos.

Remember to handle potential errors, clean up temporary files, and consider processing time for larger videos. Testing with various input formats is crucial to ensure robustness.

hey there! for circular vids, you could try using ffmpeg. it’s great for video processing. something like:

ffmpeg -i input.mp4 -vf “crop=ih:ih,scale=640:640,setsar=1” output.mp4

this crops the video to a square and scales it. then just send it as a video note. hope that helps!

I’ve dealt with this exact issue in one of my projects. Here’s what worked for me:

First, you’ll need to install the moviepy library. It’s a Python module for video editing that’s much easier to use than raw ffmpeg commands.

Then, in your handler function, download the video file, use moviepy to crop and resize it, and finally send it back as a video note. Here’s a rough outline:

from moviepy.editor import VideoFileClip

@router.message(Command("make_round"))
async def create_circular_video(message: Message):
    # Download the video file
    file = await bot.get_file(message.video.file_id)
    await bot.download_file(file.file_path, 'input.mp4')

    # Process the video
    clip = VideoFileClip('input.mp4')
    w, h = clip.size
    crop_size = min(w, h)
    x1, y1 = (w - crop_size) // 2, (h - crop_size) // 2
    cropped_clip = clip.crop(x1=x1, y1=y1, x2=x1+crop_size, y2=y1+crop_size)
    final_clip = cropped_clip.resize(height=640, width=640)
    final_clip.write_videofile('output.mp4')

    # Send the video note
    with open('output.mp4', 'rb') as video:
        await message.reply_video_note(video)

    # Clean up
    os.remove('input.mp4')
    os.remove('output.mp4')

This approach has worked well for me, hope it helps!
