View Full Version : Working with EX-1 and Prospect

Whoa! I just started transcoding EX-1 files with Prospect, and a 21 1/2 minute clip ends up as a 43 G file (!) when using the "Film" transcode setting. So, I tried the next less intensive setting, and that resulted in a 24 G file - so with a hard drive used for everything but operating programs, I will still probaby have room for transcoding about four hours of raw shoots - I assume that for most of us producing both DVD-R and BD-R, the setting just below "Film" will be sufficient? What do the rest of you working with this find?

EXCUSE ME - I placed this in the wrong Forum!

William,

Prospect will produce larger files as the compression is different. For starters each frame is compressed by itself which makes for speedier editing. You don't need to go as high as film scan, 'high' is fine as a maximum. You can do a 'difference' within after effects yourself to show that it's visually lossless. The only difference i've found is a slight colour shift in the reds which im still investigating.

The advantages are that the prospect file is a 10 bit container which means if you take shots and apply VFX or other post work (so bouncing between different applications) and recompress you are not going to get colour bandwidth problems and the results stand up with multigeneration compression.

If you're just straight editing then there's no so much of an advantage especially as premier is now supporting XDCAM files direct. However you may find that you can run more simultaneous streams of prospect as the decompression is a lot lighter on the CPU (but heavier on the drive storage though)

hope this helps

Yes, it does help! Thanks.

I am continuing to use Prospect versus the new EX-1 feature of PP CS3, as the latter has posed some insoluable problems for me - and in using the new Adobe features, I haven't figured out yet how to create avi files with them.

Same story Bill - the 3.2 update for the EX1 footage works fine until you try to create an output file.
