16mm converted to 10 bit uncompressed work flow
Dear community,
I received 16mm footage converted into 10 bit uncompressed. My Mac Book pro couldn’t deal with the files (too slow, too much rendering, etc) So, I converted it to Apple Pro Res HQ through media manager and edited it that way. then, I made a quick time with current settings and in compressor converted it to whatever setting there were in the best quality DVD 120 min setting. Then, I made a DVD in the DVD studio pro and…. ta dam! doesn’t look so good…. where did I go wrong? Thank you. -

When you say it doesn’t look so good, do you mean it looks heavily compressed or what? When you exported out the QT of your sequence does it look okay there? If it does then the problem must be with something that you’re doing in the compression for DVD.
How long is your sequence? The “DVD Best Quality 120 mins.” setting in Compressor uses a fairly low bit rate, so if your sequence is short enough you can use a higher bit rate, but how high you can go depends on how long your show is, whether you’re burning to DVD-5 or DVD-9, and how much space your menus and anything else you’re putting on the DVD take up.

Too slow means drives can’t keep up with uncompressed. Too much rendering suggests you had the wrong sequence settings.
So what are the sequence settings because I suspect you have something awful like DV or AIC which means you have been through transcoding hell before you made the final mpeg2 for a DVD which is always a heavy hit.

oh, great. the film is not longer than 5 minutes now. I didn’t realize that the default DVD setting had this pitfall, thank you. in terms of the look, it’s grainy and (it’s b/w) it lost a lot of info in the dark and light areas, in other words it looks too rough and contrasty

well, i did convert the 10 bit uncompressed into apple pro res. I thought that the 10 bit is just not a proper editing codec, but tell me if I’m wrong. was the conversion into apple pro res an unnecessary step?

hi
10bit uncompressed should be fine to edit with, but you need a drive fast enough to play it. Firewire minimum. Dont try and play it off your laptop hard drive cos it will stutter..

No for HD.
At least you will need an e-SATA RAID, and not all of them will do it.

thank you. so, I have a g-raid with FW 800. do you think e sata is better? i could try to edit from the 10 bit, but I was really hoping to use the apple pro res. doesn’t it keep like up to 90 percent quality? I think my mistake is in the compressor and DVD studio pro. I must find the right settings there. any ideas for that?

Hi Irina,
Lets say that Prores keeps a 99,9 % of the quality.
Forget about Uncompress. Also try to avoid using the Media Manager for transcoding.
Use Compressor, or MPGStreamclip.
FW 800 will be enough unless you intend to work with many layers.
For long duration DVDs, you should consider some other application (BitVice, CinemaCraft, Episode,..) instead of Compressor.
Cheers,
rafael
