Another Bogart 2.3c caution: HDV to DV internal downconvert
Posted: Fri Jul 10, 2009 3:58 am
Yesterday I completed another HDV Project, the first one using Bogart SE 2
3c and authored/burned an SD DVD.
The results were lousy with very evident motion "shimmering" artifacts.
This surprised me as I had burned HDV Project to SD DVD with 2.1e with great
results.
So I did a manual HDV to DV downconvert by using the Clipboard to transfer
footage to an 16:9 SD Project.
Looking at the results showed the same motion artifact, albeit not as
prominently, but I was sure the further MPEG2 compression that rendering to
SD DVD requires would make the problem worse and more obvious and it most
certainly did.
To say I was very unhappy was an understatement.
I tried exporting the HDV Project out to HDV tape via firewire and then back
in letting my cam do the HDV to SD downconvert live as it was inputting and
then authored and burned an SD DVD.
That DVD looks great.
So I thought I'd save some of you some time and heartburn.
Anyone can check and verify this for themselves by just internally
downconverting a little HDV footage with motion (people's heads in motion
really shows it).
So I advise those currently editing HDV and making SD DVDs on Bogart SE 2.3c
to use the out to HDV tape and back in again letting the cam do the
downconvert until this is addressed.
I have reported this bug to MSUS and I expect they will address it with the
next upgrade version.
To be clear, this only effects internal downconverting HDV to DV as HDV
edited work burns to the Blu-ray AVCHD DVD format with excellent results and
DV footage and pre-downconverted HDV to DV footage works well with 2.3c in
my experience so far.
The good news, Jörg has already responded that this bug has been replicated and fixed and will be in the next upgrade version.
