Quicktime BMD codec export query
Hi all,
Thought I’d post here as this is more of an FCP query than BlackMagic.
As per a previous post, client requires a quicktime in HD using the BlackMAgic 10-bit YUV codec. Source material is HDV, edited in HDV timeline.
I originally placed the edited HDV clips in a new BM10bit sequence, then exported a self-contained FCP movie. Whilst in the correct codec, client couldn’t open movie as no .MOV extension… nor could they append file or get it to work in any way. They insist on using ‘Export using Quicktime Conversion’ as the solution. Not a problem, but…
Is there any point in going through the ‘place in a new sequence’ step described above. or should I just export from the HDV timeline using the BM 10-bit codec? Will that merely take the compressed HDV material and create a pristine, 10-bit version of all the cruddy HDV artifacts (I’m talking around graphics here) – do I need the extra step of the 10-bit sequence?
As ever, your wisdom is appreciated…
Jason

Blackmagic use the Apple (10/8bUnc) since a couple of years. You should only use the old BM codecs if your client need to play the movies in a PC.
To go from HDV to 10b U is worth if you apply a Chroma Smoothing filter before the CC.
Try to avoid export using QT conversion.

Hi Rafael
Unfortunately the client is insisting. I can;t find another way to make it work, so Export using FCP conversion it has to be – for now, at least. They use the free BM codec so that’s a fixed thing too.
Any thoughts as to the export from HDV timeline vs export from a 10-bit one?
Jason

The problem is that the QT conversion works only in 8 bits, so there is not point to use the 10b codec. 8b unc would do the job. But clients are clients.
To export fom a 10b time-line is worth if you are setting a lot of effects or importing high quality graphics. Also if you are adding Chroma Smoothing and color correction. You see the result of those effects when you increase the bit-depth of your sequence. If you make a chroma smoothing to your HDV footage and let your sequence as HDV, almost all the improvement of your picture desapear when you export as HDV because you are recompressing again. But if you change your sequence to 8 or 10b Unc, them you really see the effect. The picture looks far more better.
Normally I work like that. I film and edit in DVCam, but when the movie is cuted, I change the sequence to 8 or 10b Unc. Them i add the Nattress “Chroma Sharpening” filter and them color correction. From there I export to Compressor and the MPG2 looks great.
Have a try.
Cheers,
Rafael
