"""A CLI to run CausalVideoTokenizer on plain videos based on torch.jit.
|
|
|
|
Usage:
|
|
python3 -m cosmos_tokenizer.video_cli \
|
|
--video_pattern 'path/to/video/samples/*.mp4' \
|
|
--output_dir ./reconstructions \
|
|
--checkpoint_enc ./pretrained_ckpts/CosmosCV_f4x8x8/encoder.jit \
|
|
--checkpoint_dec ./pretrained_ckpts/CosmosCV_f4x8x8/decoder.jit
|
|
|
|
Optionally, you can run the model in pure PyTorch mode:
|
|
python3 -m cosmos_tokenizer.video_cli \
|
|
--video_pattern 'path/to/video/samples/*.mp4' \
|
|
--mode=torch \
|
|
--tokenizer_type=CV \
|
|
--temporal_compression=4 \
|
|
--spatial_compression=8 \
|
|
--checkpoint_enc ./pretrained_ckpts/CosmosCV_f4x8x8/encoder.jit \
|
|
--checkpoint_dec ./pretrained_ckpts/CosmosCV_f4x8x8/decoder.jit
