how do Sony DV camcorders encode frames? TFF or BFF
I have a Sony DCR-TRV103NTSC, its a Digital8 camcorder. I recently tried doing an encode using Procoder, but it asked if the source was TFF or BFF? How do i figure that out or do any of you know?
there was an answer about that in the FAQ but I couldnt figure out if what was seeing is right... please help also, when making DVDs that are ... DVD compliant, i should set it to encode TFF right? |

whoa, in the guides and other places, it says the frames are rarely ever BFF, and op in #doom9 even told me TFF
here's my script that i got from Fred Thompson: #LoadPlugin("D:\Filter\DeGrainMedian.dll") LoadPlugin("D:\Filter\RemoveGrainS.dll") LoadPlugin("D:\Filter\RepairS.dll") LoadPlugin("D:\Filter\SSEToolsS.dll") Import("D:\Filter\DeHalo_alpha.avs") Import("D:\Filter\LRemoveDust.avs") aviSource("D:\Test Avi\test.avi") ConvertToYV12(Interlaced=True) SeparateFields() #DeGrainMedian(limitY=2,limitUV=3,mode=1,interlaced=true) DeHalo_Alpha() LRemoveDust_YV12(10,1) Weave() based on this script, does this reverse field dominance? or should both settings on procoder be set to BFF ? |

I don't know what guides you looked at, but the DV to DVD guide hosted by doom9 says that DV is bottom field first.
From the guide http://www.doom9.org/dv/guide.html: Quote:
Also, since you are working with NTSC you should really be using the ReInterpolate411 filter. Place it as your first filter after AviSource. DVDs can be either TFF or BFF. If you really want to convert to TFF, you can add the line: Code:
DoubleWeave().SelectOdd() But I would leave the video bff and encode it bff. Last edited by Video Dude; 17th March 2006 at 03:41. |

why do i need ReInterpolate411? I used to use that before, but I no longer use it because i'm following someone else's updated script. Whats so integral about that function?
also, what do you all do when you encode with filters? do you do a pass as a loss less stream once in... lets say virtualdub, with your filters, then encode in CCE, HC, or whatever encoder you use? seems like this would save a lot of time. |

From trbarry's homepage:

I do all passes in CCE and leave it to encode overnight. I don't create a temp lossless file using virtualdub. |

@ou8thisSN:
There is no downside in creating a lossless intermediate file regarding quality. It needs lots of hdd space, but it can save much time. But sometimes it can be slower than frameserving, too. It depends on your script (the filter chain used) and the number of passes. bb |
