Compression for the Web

Hey guys, I just joined the forum here, but have owned the HMC150 for a few months now.

I have been tinkering with Compressor and Quicktime Conversion to try and find the best possible option for the web. It has lead me to H.264 but I was just wondering if any of you had any input on the matter that could save me some precious time. I'm on a pretty nasty time constraint with a client, but I want the footage to look amazing. Planning on uploading it to Vimeo and Youtube.

Oh and if this question has already been asked and answered in a previous thread...I apologize in advance. :Drogar-BigGrin(DBG)

Thanks

Ryan
 
I use AAC/mp4 (vegas) output with a variable 7-15mb bit rate at 720p which makes pretty small files. I found you can get great quality over other file formats for the size of the file.

I use AAC/AVC as well, but I just stick to a constant 16mb bitrate since I rarely ever get close to the upload limits of Vimeo Plus or YouTube. The biggest thing I've found (personally, with Vegas) is that rendering with 32bit float instead of 8bit produces much better results after internet compression processing. I've stated elsewhere that if I were to take a project in Vegas and render two versions...8bit and 32bit float...and subject them both to a compression heavy site like Vimeo, the 32bit is clearly better when dealing with pixelation in darker areas and artifacting in motion.

Just my observations.

Thanks for sharing - I was noticing the same thing.
 
i am wondering the same thing

i am definitely interested in this too. i use compressor and every time i export i lose so much richness from the color and also fidelity from the audio. it's like clothes that lose their color in the washing machine, just dull. i've tried so many things - i hope someone has the secret to compressor settings (esp for youtube or vimeo). thanks for posint this!

Are you going out to Quicktime? There is a known gamma-shift issue that I can't believe Apple hasn't patched yet (it's been years).

Here's the fix (Quicktime Pro required): http://www.videocopilot.net/blog/2008/06/fix-quicktime-gamma-shift/
 
I was reccommended by a pro videographer friend of mine to use 'squared5-mpeg streamclip' have not used it yet except for one conversion. Anyone have thoughts on that program vs compressor?
 
Isnt the gamma shift a problem on Windows/QT users? I have never noticed a shift being on the Mac when encoding to H.264.

I have been using MPEG Streamclip for a while and really like it. Works well and its free. I export a Quicktime Movie from FCP and then bring that into Streamclip. Maybe not the most efficient, but I have good results and never have problems. The one issue that I have is that Streamclip has no batch feature so you can only export one file at a time...a big problem for me because I do a lot of work for clients where I export 5, 10, 25 clips at a time.
 
streamclip is awesome... compressor is really good too, i guess it depends on personal preferance. I personally use both! =)
what are you looking to do?
