# extract frames (the output folder should have name 'input')
# scale_ratio means the image is scaled
python extract_frames.py --video_path ../../sample_video/001.mp4 --output_dir ../../sample_video/001/input --target_fps 10 --scale_ratio 0.5
# Run sfm to get camera poses (change to your COLMAP.bat path (tesed on Windows))
# may takes minutes depending on the resolution and video length
python convert.py -s ../../sample_video/001 --colmap_executable "D:/COLMAP/COLMAP.bat"# Train 2dgs (change to your path)
python train.py -s ../../sample_video/001 --iteration 15000
# Extract Mesh from weight
python render.py -s ../../sample_video/001 -m ../../sample_video/001 --skip_test --skip_train --mesh_res 1024 --depth_trunc 5
the output mesh will be found in sample_video\001\train\ours_5000\fuse_decimated.ply
