Hello everyone,
I would appreciate input from more experienced members as I would like to simplify things for myself and others interested in NTSC DV to DVD conversions.
I am in the process of thinking through the process of quality dv (home video footage) to dvd conversions (TV viewing, interlacing to be conserved, i.e. no de-interlacing). Reading postings gave me multiple options and questions. I have went through several workflows and decided to use something like this:
NTSC DV capture using DVIO avisynth ->filters->frameserve to vegas-> transitions/effects/trims-> frameserve using Debugmode FrameServer to CCE (possibly DVD2SVCD's RoBa)
Some key points that I have found from reading: in order to preserve quality, minimize colour conversions (e.g. workflow above would go from YUV 4:1:1 in DV to YUY2 4:2:2 in Avisynth for filtering to RGB in Vegas to YUY2 (or RGB) as input for CCE to mpeg2 YV12 4:2:0). There are also some issues with colour space range luminance and different DV codes that could be used..
Frameserve DV using Avisynth with filters (Reinterpolate411 (YUY2), CNR2 (YV12 and YUY2), Removedirt (YV12 and YUY12)) to Vegas:
2 options (both described http://www.avisynth.org/q2.3) or here: http://forum.doom9.org/showthread.php?s=&threadid=49964&perpage=20&pagenumber=1) and (http://forum.doom9.org/showthread.php?s=&threadid=47194):
- using VFAPI
- or using AVI Wrapper (makeAVIS (included in the ffvfw codec package]
Add effects/transitions in Vegas. Frameserving out of Vegas in RGB or YUY2 to CCE :
- using Debugmode FrameServer (http://www.debugmode.com/frameserver/)
Questions:
Based on other members experience what are the weak points in this workflow?
Which DV codec do you recommend?
How to preserve luminance range from DV capture to dvd encode?
What is the practical difference between VFAPI and makeAVIs?
Any comments on frameserving out of Vegas in RGB or YUY2 to CCE?
Can anyone comment on using DVD2SVCD's RoBa to convert DV to DVD?
What about alternative approach which would minimize colour space conversions (never go through RGB except for transitions and effects):
- go directly from NTSC DV capture using DVIO ->avisynth, filters, frameserve to CCE (possibly DVD2SVCD's RoBa) to make mpeg2 file.
Then using same NTSC DV capture and any video editor (vegas, windows movie maker2, etc.) produce transitions, effects, and export only these transitions/effects to CCE mpeg2 file. Remove, join, edit direct encode of the NTSC DV with transitions mpeg2 produced separately using mpeg2 editor (any of the tools listed in the www.videohelp.com, e.g. mpeg joiner, videoredo, etc.)
