Compression for YouTube
Up to DistributionCompression for YouTube
There was a post on the CrunchGear blog that Alex found that I find particularly helpful, and I'm sure the vast majority of you will too!
There are specific How-To instructions on compressing your video to get the most out of posting on YouTube.
Check it out!
Re: Compression for YouTube
They are using one pass flash seven to encode so it's not going to be pretty compressed no matter what you upload, but maximizing the file you put in is key in my opinion. It's a little time consuming to have to set up multiple encodes to hit the right spot, but if you have an action piece with lots of movement, you are going to want to spend the extra time.

Re: Compression for YouTube
DIVX is a great codec as well for High Quality stuff. But is BIG!
Speaking of DIVX - you should send your videos to Stage-6 six as well Michelle (in response to your distribution blog).
Re: Compression for YouTube
We hardly go over 50 MB in file size, which means you upload much faster and the qualit is awesome! H.264 is very slow to process, but it's the best web codec EVER! Setting the resolution higher than 320x240 doesn't affect file size as much as you'd think, and the end result is much better after YouTube recompresses. If you don't already, you should also shoot and edit in 24P. It looks more like film and takes less space! CHEERS!

Re: Compression for YouTube
The thing YouTube doesn't tell you is you can go higher resolution than 320X240 when you submit. Although it ends up that resolution, you can make it bigger as long as it fits under 100mb. You want to submit it big because Youtube recompresses your file on top of your compression. I just find H.264 the best quality at the lowest file size.
You can test uploading different qualities and pick which one looks the best. Set a video to private while you're testing, then switch it to public when you approve!
Best!

Dave, these specifications were FANTASTIC -- of all the tips I found online, they by far produced the best quality. Thanks!
Re: Compression for YouTube
we have been using similar settings to what dave suggests, if you are not, here is something very important to consider:
flash 9 supports h264 quicktime playback.
what does this mean to all of us? simply put, youtube is about to switch from flash encoded video to quicktime under the hood. they save all the original files that we upload, and will be/are transcoding these into qt h264 files. if your uploads were already in this codec, the re-transcode will be kinder to you. so when the switch does happen, your old vids will look better. side note to this changeover is that youtube will be more iphone/podcast friendly... the ramifications of which are exciting.
