About spacetime_.mp4

[Mxfg-incense]

After I run
PYTHONPATH='.' python plenoxels/main.py --config-path plenoxels/configs/final/DyNeRF/dynerf_explicit.py --render-only

There is a .mp4 file in the .log folder

2023-02-17 02:39:46,848|    INFO| Saving video (300 frames) to ./logs/realdynamic/cutbeef_explicit/spacetime_.mp4
2023-02-17 02:40:00,764|    INFO| Saved rendering path with 300 frames to ./logs/realdynamic/cutbeef_explicit/spacetime_.mp4

But this openned video file is like this

If you want to generate the space-time decomposition video then the flag to use is --spacetime-only rather than --render-only. To render, you also need to specify a --log-dir with a trained model checkpoint; otherwise it will use a model at initialization which won't look like anything.
