Compression/File Size Question *IMPORTANT*
Hi I am new here and I have been trying to compress my videos for work to the right size and I have not been having much luck. I have videos that are anywhere from 30-45 minutes long and I need them to be just under 600MB ideally. When I compress them using Quicktime in HD 16:9 it comes out to around 1.7ish-3GB. When I compress them as an MPEG4 (.mp4), it is too small and comes out to about 100MB.
If you guys have any suggestions please let me know. I need to figure this out by tonight or I could be in some trouble. Thanks

h.264 is the current standard for Web video and for all “smaller” deliverables. There are numerous h.264 presets in Compressor in the “Web” directory, with the 300kbps and 800kbps versions being the most likely candidates for your purpose. The later is usually best for showing to clients, but the 300kbps version might be just fine. I’d suggest you try both and compare quality and file sizes.

Note also, in Compressor’s Inspector window, it gives you an estimated file size…so you don’t have to encode it first to know if it will make it small enough.
The estimation is not terribly accurate, but it gets you in the ballpark.
You can then do a short test encode to see if you are happy with the quality.
All of the presets can be tweaked further if you are not getting the results you need.

Thanks. I will take a look at these things.
