[sean edwards] “how should i export from fcp should i compress”
[sean edwards] “then what format should i use to transfer it to a usb drive”Those all depend on what the purpose of the delivery is for. You did not say. Is it to be put online, broadcast, just a preview, what.
Now is this flash drive going to be only used on a mac or is it also going to be used on a windows computer. This is important because by default flash drives come formated FAT32, this for mat can be read by both windows and Macs however there is a file size limit associated with the format. So if the file os going to be larger then 4GB then you will need to format the drive differently to accommodate the larger size. The issue here is that the other formats that will accept larger files are ether windows only or mac only. You can however purchase some 3rd party software for windows that will read the mac formated drive.
There are no “technical solutions” to your “artistic problems”.
Don’t let technology get in the way of your creativity! -
Hi Sean,
A 90 minutes movie in a GB file means that you are allowed to 1’48MB per second of movie.
That means a data rate of 11’85Mbps. This for video+audio.
With this data rate you can keep a very high quality for SD with MPEG-2 or H264.
For HD I would go H264. With such a data rate, perfect to present something 1920×1080.[Zane Barker] “by default flash drives come formated FAT32, this for mat can be read by both windows and Macs however there is a file size limit associated with the format.

Yes I think you will find the limitation to write from a Mac to a Flash card a file bigger than 4GBs.
I don’t know the reason of this limitation with the FAT32.
This limitation it happens for example with EX-1 SxS card. You can write in camera an almost 32 GBs file, but when you try to upload from your Mac to the SxS card, the limit file is 4GB. Is also formated FAT32.
Perhaps with a PC you can upload an 8 GB file.

Rafa, I’ve got a question about DVD vs. Compressor assets that are used to burn the DVD in DVDSP. I deliver a 60-minute show for broadcast every week, and the format I’ve been delivering is DVD. How much of a difference do you think there is between the Compressor assets (.m2v and .ac3 files) and the actual burned DVD? Would it be cleaner to deliver the two files on a flash drive instead of encoding them onto a playable DVD? Does it matter that much?

Hi Paul,
With a DVD you always have to think about the DVD player.
If you set the data-rate too high some players can have problems to cope with too much information.
The pictures/sound can play choppy or even freeze on the screen.
The same file played from a cheap computer would play without problem.
So in the moment you don’t need to make a DVD you get free of many constrains.[Paul Campbell] “How much of a difference do you think there is between the Compressor assets (.m2v and .ac3 files) and the actual burned DVD?

Now you can compress the .m2v and .ac3 files, with the top data rate that Compressor allows. Also you can start to use short/open GOPs. All this means less compression for your movie.Yes put your assets in a Flash memory or, better, in a Double-layer Data-DVD. You won’t have the 4GB’s file limit of the Flash.
If you are interested in this kind of MPEG-2 distribution workflow, ask Craig Seeman (he knows a lot),
and have a look to “Episode” which is light-years over Compressor.
Cheers,

Thanks, Rafa. I’ll start looking around for Episode.

Hi Paul,
I forgot.
In the “Compressor Inspector> Stream Using” you can select “Generic” instead of “SD DVD”.
This will let you to increase the data-rate to 34/40 Mbps (!) instead of the 7’7/9 Mbps for the “SD DVD”.
