I have recorded some youth concerts recently with my Canon XH-A1 set to the 24F format. Capture and edit work fine in Avid Liquid with the timeline set to 23.97, fuseing works well too. All media looks great played with Windows media player.
When I import the assets into DVDit, there is a HUGE amount of grain resembling a snowy tv image.
Encoding with TMPGe with 3:2 pulldown clears the grain, but it seems like considerable detail is lost.
I have previously used DVDit to output HDV2 60i work which has been more than satisfactory.
I do not understand the 'snow".

John, without doing so much more examining, I think that dvdit pro not will handle progressive hd, the tests I have done in the past with preencoded progressive files from adobe mediaencoder have all been reencoded whilst interlaced runs straight through.

Be absolutely sure it is 24p.

if its 24f wrapped in a 30P file, it will be non-compliant as Blu-Ray does not
support 30P video.


I have found DVDITPRO HD ALWAYS accepts properly encoded files so it's
likely a setting in the file export or the mpeg compressor you are using
that is causing the problem.

DVDit does accept the file, and the player says that the settop player identifies the media as 24p, the TV also confirms the 24p output of the player as well.
BD is not the problem, it exists when creating a standard def DVD that the grain exists...

[borjis]

but is it transcoding it?

as we all know dvd it pro hd will import non-compliant files and warn if they are not (6.4 always says they are non-compliant even though they are BUT it doesn't transcode)

If you have a standard def downconverted mpeg2 you are bringing in
and it muxes to a dvd without transcoding, I don't see how it could
be more "grainy"

Of course DVDit must transcode an HDV input file to output a standard DVD. The point is that the grain is visible within the preview window before any output transcode. Windows Media player plays the files with perfect clarity. it seems that the problem is with DVDit.
Transcoding the HDV2 24p with TMPGe to DVD format avoids the grain.

[borjis]

seeing grain on a preview before transcode makes no sense, but DVDIT has always been
a tricky app.

weird.

I wish I had a suggestion to help but I don't.


and by the way, TMPG author can take HDV tapes STRAIGHT to BD-R
with no transcoding. It just analyzes the stream and "patches" the gop
structure to comply with BD standards.

It's the only app that does it properly. TSMUXER and TSREMUX doesn't build
a fully compliant BD-R disc, but TMPG author does.
