Youtube Compression settings

I tried the setting outlined above and my 4 minute video is coming out to about 118MB. Is there a way to retain setting but make size a bit smaller? Youtube limit seems to be 100MB. also, I did this using quick-time - I could not find the 640x480 in compressor under the MPeg4 options. Any thoughts on this?

.flv conversion

.flv conversion

I originally found out about converting to .flv as a way to keep stereo sound in my vids. Me and some youtube friends have been using these settings with good results for audio in stereo. we use "any video converter" a free download to convert our videos to .flv.

video settings
192 kb/s bitrate
30 fps framerate
320x240

audio settings
128 kb/s bitrate
44100 mhz stereo

we were operating under the assumption that the combined bitrate audio 128 + video 192 = 320 must be under 350 or thereabouts to keep youtube from tampering. however video at 192 is really not great. I am now under the impression that it is not bitrate but total file size of the .flv that determines whether youtube compresses. based on that assumption I will be doing some tests with videos of lengths one minute, two minutes, and 3 minutes. I am thinking that the file size must be around 20 mb or less or else it will be compressed. i should be able to turn the video bitrate up to over 1000 on the one minute vid, maybe more, I may even be able to do 640x480. I'll get back to you. One thing to consider also is that youtube may change their compression settings depending on how many people are trying to upload at a given time. Another reason is they may be holding out to offer a premium service which allows high-quality full-length films for a monthly fee. who knows. One things for sure, it's a fantastic technology and a great service even with it's limitations.

OK, because this issue is getting me really worked up, I tested Kyle's claim about YouTube not recompressing FLVs:



I took a 20.7mb FLV and uploaded it to YouTube. According to my computer, 'Date Modified' is 6:17pm.

I went to http://downthisvideo.com/, one of the many YouTube video downloading websites, and downloaded the same video.

The file that appeared in my Downloads folder was 6.8mb, 'Date Modified' 7:01pm. Visually, it looks slightly (but not very noticeably) more compressed than the file that was uploaded.

I'm not Sherlock Holmes, but to me this suggests YouTube IS in fact recompressing FLVs.


I feel a bit stupid for not running this very obvious check earlier.

Has anyone else looked into this?

I will be doing my own tests soon. My primary interest is in keeping decent quality stereo sound. of course my secondary goal is to get the best quality vid possible while still keeping the stereo sound. I would suggest just as a test, simply cut off about 30 seconds of your film, change it back to .flv using the same settings. that should get it down to about 18-19mb. let me know if that works. peace
 
Doesn't let me upload .flv files to youtube. Think it hates me. Or maybe i just tried uploading a .swf file, i dont know.
 
Check out http://youtube.com/watch?v=bTiZYqQgtFk When you do, hit the view in "high quality" button at the lower right side of the video screen below the word views. You can toggle between the two to see the difference. Not sure what triggers this function in youtube. I stumbled on it by accident. May be the original high bitrate upload.

To get your video at or under 100mb what are you setting your Data Rate at? I have mine set at 900 right now and when the compression was done my 8 minute video came out to 53mbs! I was told to try to get it as close to 100mb as you can.

My settings are as follows:
Frame rate: 29.97
Key frame every 24
Quality: high
Encoder - Fast /Single Pass
Data Rate: Restrict to 900
Size: 320x240
Filters: Sharpen edges 1.0 & Deinterlacing - odd 1.0
Footage shot in 24p format

Has anyone considered using www.brightcove.com I have seen some really nice looking videos that were done using that.
 
man, youtube lets you upload 1024 MBS now. i usually just don't compress my file at all anymore so i can upload like a 800 mb file and almost NO quality is lost from their compression. a little sure, but nothing like before when i was having to compress it to under 100mbs.

also the 'view in high quality' option, which usually comes up based on the users bandwith, makes the quality almost perfect. check it out guys, things are really changing for the better on youtube.
