HD vs SD Compression

Ever notice how you can record a 1 hour SD show and it takes like 3.3gb for highest quality, then when showsqueeze (DIVX) runs it's down to something like 1.1gb.
But when you recorde an HD show, and after streamsnip it's 6 or 8gb of data. Then when it compresses with DIVX its down to 300mb?

Thats a pretty substantial difference in size. My HD recordings are OTA, but are you seeing the same type of compression with the HDHR?

Re: HD vs SD Compression

My DIVX compressed shows are about 2GB per hour. I use DIVX HD High which I find has visibly better quality. What are you compressing down to?

Re: HD vs SD Compression

digital will probably compress better simply because the picture is cleaner, but probably not THAT much. you are most likely using a lower divx conversion setting on the digital conversion.

Tom, that's what's so strange. My WWE on SD was 2 hours and was 6.9gb -> 2.52.
The Smackdown on HD OTA was 13.25 ->1.51gb.

I guess it makes sense since you're doing less compression than I am. Just such a huge reduction in size.

I didn't adjust the compression from the web admin, but looking there I'm not sure what its using. It shows DIVX Portable (Medium) as one default and the DIVX Home Theater (HIGH) as the other default.

I used to compress with MPEG, but the audio was garbled. Since changing to DIVX though audio and video are in sync. Sometimes video could be sharper, but regardless it is always better than SD (before and after compression)

Re: HD vs SD Compression

Neither of those compressions is HD. You're compressing all the way to SD. That's likely why it is so small. Only the Divx HD compressions are HD.

Check the resolution of those, you're most likely under the DVD resolution of 720 x 480...
