Best compression for the web

[Daniel Low]

Huh? What?
With H.264 as the CODEC in all, mov, MP4 and F4V will only vary in file size ever so slightly. Like the different between a sheet of paper and a sheet of thin card.

The quality will be identical.

Drew, some of what you say is good advice, the other stuff is crap. Sorry to be brutally honest.

No offense taken. I’m just trying to learn anything I can, some good info and some bad but with comments like yours, it slowly helps me weed out the bad.

Then I must pose a question also. I just rendered a video in 3 different formats .mp4, f4v, and .mov. The .mp4 and .f4v were basically same size (1.6MB & 1.7MB) but the .mov was 10.3MB. Is it because of the default setting of .mov and it’s bitrate? I mean, when exporting the .mov, I get quality settings of (low,med,high,etc..), that is basically dummy settings for bitrate… correct?

It’s all meaningless without details. If all you’re getting is “low, med, high” there’s no way to compare. If it’s a “Quality” setting, then the encoder is making decision based on content and that bears no relation at all to what another thing with settings is doing.

Defaults are meaningless because the settings may not match. After all, Nigel Tufnel’s goes to 11.

Hello guys,

Craig mentioned the “hinted” metadata on the .mov. I was wondering what that was? Sorenson gives you the option of “hinted” or “not hinted” in the compression settings. Hinted being associated with “streaming” – actually the choice is between “streaming-hinted” and “non streaming -not hinted” Can someone explain to me what that is exacly? In what way will it affect the video?

Another thing i meant to ask: sometimes a compressed video gets pixelated ate scene change and then gets better after a second or two. Im guessing this has to do with the “keyframing at scene change” option. Is that so?

cheers
