Prospect HD is also a fine choice, it will support full raster 1920x1080 4:2:2 10-bit captures from HDSDI .

What practical benifit will be see with the 4:2:2 over the 4:2:0? i KNOW THERE IS MORE EFFECTICE RESOLUTION BUT IS IT VISUALLY SIGNIFICAT?

This is significant. Keying particularly but even just red objects look much better in 422.

Hi All!
what is the best way to convert EX1's files to cineform?IF i input BPAV folder then Hd link makes all copies in the same folder where original file is..if i have lots of clips then it takes lots of time move avi's somewhere else.I tryed also export from clipbrowser mxf files..and converting then avis.its like better ,because all of them in one folder after conversion.But requies one additional conversion..or do i miss something??

Best Regards

Raul

Raul, I actually had the same workflow question!

But I think it'd be better to open a new thread for it, here:

can HDlink convert the long GOP MPEG-2 format files directly from a camera memory card into MP4 files on a computer harddrive?

Or do you always transfer and convert into .MFX files on the hard drive, and then do a batch convert to MP4? I thought I read somewhere that this double conversion loses resolution?

David Newman · November 28th, 2008, 11:35 AM

We never convert to "MP4" we can convert directly from. The CineForm outputs are AVIs or MOVs for post.

Robert Bobson · November 28th, 2008, 01:19 PM

Then I guess my question should have been - Is it better (or even possible) to transfer and convert the long GOP MPEG-2 format files directly from the EX1 camera memory card onto the computer hard drive as AVI files all in one step, without converting to .mxp files first?

Or am I missing something here??

David Newman · November 28th, 2008, 01:39 PM

Quality will be the same, yet the direct MP4 conversion bypasses a step, so I would think that is preferred.

Robert Bobson · November 29th, 2008, 06:27 AM

good to hear that the quality is the same. easier for the field producer to transfer to his Hard Drive as .mxf, then I can convert to avi in-house.

another question - can "Prospect HD created avi files" be edited from a single firewire connected hard drive? is the speed enough??

thanks for the reply -

I have done a clip browser conversion to MXF of several files, then HDlink conversion to Cineform AVi (HD quality) , all files are 1080i50 from EX1.
Then just dropped them on the CS3 timeline and exported (File/Export movie).
Stangely the export is very slow, like if the video is recompiled.
quality of export is the same setting (hd quality) as capture (in that case likely a conversion)
another question is that capture prefs of HDlink do not show the HD Quality optimized setting that is available in premiere export setting. Why ?
