• How to Use SVG Image Files Directly in FFmpeg ? [closed]

  10 mars, par Pubg Mobile

  I generated a bar chart race using the Flourish Studio website and captured the frames as a PDF sequence using a Python Playwright script. Then, I converted all the PDF files into SVG format using the following Python script, because SVG is the only image format that maintains quality without loss when zoomed in :

  


  import os
import subprocess
import multiprocessing

# Define paths
pdf2svg_path = r"E:\Desktop\dist-64bits\pdf2svg.exe"  # Full path to pdf2svg.exe
input_dir = r"E:\Desktop\New folder (4)\New folder"
output_dir = r"E:\Desktop\New folder (4)\New folder (2)"

# Ensure output directory exists
os.makedirs(output_dir, exist_ok=True)

def convert_pdf_to_svg(pdf_file):
    """ Convert a single PDF file to SVG. """
    input_pdf = os.path.join(input_dir, pdf_file)
    output_svg = os.path.join(output_dir, os.path.splitext(pdf_file)[0] + ".svg")

    try:
        subprocess.run([pdf2svg_path, input_pdf, output_svg], check=True)
        print(f"Converted: {pdf_file} -> {output_svg}")
    except FileNotFoundError:
        print(f"Error: Could not find {pdf2svg_path}. Make sure the path is correct.")
    except subprocess.CalledProcessError:
        print(f"Error: Conversion failed for {pdf_file}")

if __name__ == "__main__":
    # Get list of PDF files in input directory
    pdf_files = [f for f in os.listdir(input_dir) if f.lower().endswith(".pdf")]

    # Use multiprocessing to speed up conversion
    with multiprocessing.Pool(processes=multiprocessing.cpu_count()) as pool:
        pool.map(convert_pdf_to_svg, pdf_files)

    print("All conversions completed!")


  


  Problem :

  


  Now, I want to use these SVG images in FFmpeg to create a high-quality video file. However, FFmpeg does not support SVG files directly, and I have read that I must convert SVG files into PNG before using them in FFmpeg. The problem is that PNG images reduce quality, especially when zooming in, which is why I want to avoid converting to PNG.

  


  Is there any way to use SVG files directly in FFmpeg or another method to convert them into a high-quality video while maintaining full resolution ? Any ideas or suggestions would be greatly appreciated !
