Uploading 20 Gb. of raw footage?

IDSN be faster then DSL???
WOW in our Country we make fun of People that still use ISDN…😉

Yes, this.
I thought of that idea (encoding to H264) after I went to bed last night, and today I’ve been doing some tests. It’s workable… I think. The only problems I’ve seen so far are:
-The default H264 encoding preset in Compressor outputs a progressive file (it deinterlaces automatically), which is a no-no in our case.
-File sizes aren’t as small as I expected. With the default H264 preset, the resulting file is around half the size of the original, which means that it’s still 10 Gb.
-Also, there’s the gamma shift.We’ve also been asking around and found some companies with faster Internet connections that can give us a hand, etc., so I think we’re out of the woods. Thanks again to everyone who responded.

Paulo,
You are a Pro. Stop using “Default presets” and learn how to customize them.[Paulo Jan] “-File sizes aren’t as small as I expected. With the default H264 preset, the resulting file is around half the size of the original, which means that it’s still 10 Gb.”
Limit the data rate and ALWAYS set Key-Frames Auto.
With a 10Mbps (10.000Kbps), your file will be reduced to 4GBs.
Being SD, you can still reduce it.I would recommend you trying “HandBrake’ for the H264.
– Supports Interlaced.
– Supports H264/High Profile.
– Accepts DVCPro50 sources (No prores).

“Oh, I did that :-). Problem is, the interlaced version takes more space than the progressive one. With the default preset, the resulting file takes 50% of the original. With the default preset, modified to disable frame control, it takes about 60% of the original.

Paulo,
From Interlaced to progressive can not be any big difference in file sizes. On both you are dealing with the same number of pixels per frame, so you need the same data to write the info.
The key for the file size is on the data-rate and the k-frames you set on the H264 compressor.

Not a good idea!
1) h.264 encoding is very slow on your side.
2) h.264 is not an editing codec and will need to be transcoded to another codec on your client’s end.

I agree with Dave. Satellite it or even maybe fiber feed if they are willing to pay.
You inquired earlier about how large studios are sending huge files to one another these days. Basically, you get what you pay for regarding internet service. We just upgraded to copper internet lines for $$$ but our upload speeds are about 2 MB a second. A gig only takes about 10 minutes or less to go up.

I completely agree… Trust me, when Spielberg wants to see his dailies, the studios pay, and he can see them anywhere.
It’s all about what you’re willing to pay for the luxury…

I know it sounds strange, but as God is my witness: take a 1.4 Gb. test clip in DV. Encoded with the default H264 setting. Result: 683 Mb. Take the default setting, copy it and disable frame control, in order to prevent deinterlacing (and leave everything else the same). Result: a 854 Mb. file.

Is that because you’re using the ‘automatic’ setting for data rate, and deinterlacing is cutting down on the resolution/detail the H.264 encoder will try to retain?
