I'd like to ask a question and to comment.
The question is... Out of the external TBC you've mentioned, any model has good 3d comb filter for Y/C separation? Or TBC are not designed for that?
I'd like to comment on Canopus ADVC. I know that you don't like them...
nevertheless.
1. Only ADVC-300 has built-in LTBC. ADVC-100/110
don't and are
not advertised to have LTBC.
2. I recently acquired ADVC-300 to use with not-so-important low quality old VHS tapes just to make it quick. So far I had not had any single frame dropped during my captures and that would include static/snow between clips and so forth. The only thing I experienced was disconnection during blue screen due to the fact that I was capturing in SECAM format and at the time VCR stopped, it automatically would switch into NTSC format for blue screen. So I guess in that sense LTBC is doing a pretty decent job. The TV Tuner card I have would immediately drop frames during static/snow.
