So you found your Brazilian a bit painful did you Shaun? :-)
I'm with you on the JVCPro HD tapes though they can be a bit hard to find over here. I still use the JVC-DV60DE tapes on Standard Def jobs. I'm interested in what you said about MPEG problems - can you explain explain more? |

Shaun, does the video play back OK on the cameras' LCDs when FCP reports these capture problems ?
I know it's hard to say without actually seeing them, but I've been assuming that occasional "dropouts" characterised by an approx 1 sec image freeze (no pixellation) are dirty head/tape quality issues. Cameras involved are all canon HV-30s. What do you think? |
Colin:
The errors I'm talking about indeed play back normally. My thoughts on the image freeze are mere speculation: it may depend on whether the camera has error suppression logic built in to deal with dropouts (like the blue screen that comes up on VCRs when there is no signal, for example). A freeze also SEEMS like the sort of thing that would come from an improperly closed MPEG stream as the decoder would need an "i frame" to begin playback again after a corrupt MPEG stream and then due to the GOP, it should take half a second before it sees the next "i frame". Again, mere speculation based of educated guesses here. All I can offer. |
I used the best HDV tapes for awhile, then discovered that the cheapest type that Sony makes, really are "premium". I have had no glitches with them so far and a few have been used for utility clip re-recording, a dozen times or so. At 3 bucks or less a pop, I'm not going to complain about having to pay so little.
It may actually be like the contact lens scandal. One company was selling the kind that can be used continually, in three quality-levels and prices. Then, it was revealed that the $100. type that lasted a year, was exactly the same as the $25. ones, that were rated for only a month. |

I remember seeing a Sony Broadcast poster explaining the difference with their premium HDV stock as having higher magnetic potential and a better base layer so that stretching and long term storage SHOULD have less effect. |
