-- I can't use the d2v parameter then (so won't detect eventual changes of colorimetry within the clip) ?
You can still use the d2v parameter as long as the colorimetry doesn't change at some point in the d2v. The same number of frames requirement is only enforced if colormatrix detects that the colorimetry does indeed change in the d2v file. That requirement is checked for during filter construction, so if you are able to load the script without an error then everything is fine. In the case that the colorimetry does change, colormatrix has to correctly match up input frames to frames in the d2v file to determine which frames need which conversion... thus the requirement that the number of frames be the same.

The hints wont survive tfm because by default it writes its own hints into the same bytes that dgdecode uses for hints. Unfortunately, the mergehints() workaround that Wilbert posted wont work correctly either since the frames in the saved clip wont match up with the frames after ivtc... which would be required to correctly handle changing colorimetry. If the colorimetry didn't change, then it would be fine, but in that case you could just use the d2v parameter.
