Help me pretty up my time lapse

->> I did a short time-lapse of a game day at Notre Dame. You can see it here:
http://gameday.nd.edu/experience/multimedia/gameday-time-lapse/
Looks nice and pretty viewed as a quicktime .mov file, but it looks over-compressed and blocky on the web. I don't handle the 'under-the-hood' web stuff, someone else in my office does. I give them a pretty video, it goes behind the curtain for a while and comes out looking like...that. In the immortal words of Don Corleone: "Look how they massacred my boy."
It seems clear to me the damage is being done in the conversion from a .mov to a flash file. Unfortunately I don't know what software they are using. The web guys in my department prioritize load speed above all else & don't see a problem with how it looks, so I am fighting a one man battle. Lots of folks here have done time-lapse work for the web--what software do you use to convert to flash and how do you preserve the detail in your images?
Thanks! |

| ->> Matt - while I can't help with your video question, I do want to say that the site you linked is pretty slick. I really like the "Big Picture" presentation of game photos. Good work! |

->> I did a time lapse a while back that seems to suffer the same fate on my website. However, what is interesting is that the blocky look is only REALLY apparent when there is a lot of action. It's like it can't handle cycling through the photos that quickly.

I hope someone on here has an answer. |

->> Matt, Max...
Others will most likely chime in...
But I think the encoding was a bit 'agressive'. Just like taking a RAW image and compressing down to JPEG, Quality setting 3 and still trying to display that image at 3000x2000...
Maybe ask the web team to take your .mov and compress using H.264 or VP6...Size it 640x360 to keep 16:9 aspect, with bit rate of maybe 2500 or 3500kbps...(This you will need to encode with aleast 1000kbps..YMMV..This shoul make a decent size movie, like your link and it wont have the artifacts.
I personally encoded a lot video for clients and like you need to show videos via web before final encode to web and DVD.
Not really software, but how you set the parameters for compression encoding is the fine balance.
Also, your .mov should at highest quality to begin with...it will look horrible to take an agressive compressed video to again compress to another format.
Just remember...QT, WMV and to an extent .flv are just containers that 'hold' your video. How you 'shrink' that huge video file down to web is the trick.
Vimeo has some good tips as well.

Hope this helps a bit... |

->> Good info Andrew, thank you. Saying "Make it look better!" is never as helpful as having some numbers.
My stopgap measure is to upload to Vimeo and embed from there. |

->> Hi Matt...no worries.
When I have some time, I will try to get even more solid numbers for you and your staff to play with. I learned by trial and error...
BTW, had a great time here when Coach Holtz came here for the ND Japan Bowl a while back.
Good luck Dude... |

->> Are they exporting straight from Final Cut to the video file, or using Compressor? I've had better luck with Compressor keeping things small and clean.
It is kind of problematic using MPEG variants though - basically MPEG's update the next frame with the changes from the last, which works great if you've got a pretty consistent scene that changes gradually. It has trouble with where there's quick motion or things pop into and out of the frame really fast.
You might try turning down the frame rate of the video to the same as the speed the photos are changing at, while you're creating the slideshow. That'll allow you to have fewer frames with more quality per frame. |
