i am looking at buying final cut pro x, and have noticed compressor 4.

 

what is compresssor 4? and what does it do?

 

what i essentially need to know, is does it decrease the video size?

 

as i am currently using smart convertor to reduce the size of my imovie videos from 1gb movies to 134mb movies.

 

does compressor 4 do this?

    Well, here is a kind of highlight reel: It can scale video up or down; it can transcode from one codec to another; it can change frame rate; it can add chapter markers; it can separate audio and video streams for DVD authoring; it can create simple DVDs and BD; it can change standards from NTSC to PAL and vice versa. It can do many encodes of the same file as a batch. And more…

     

    Michael Grenadier posted some highlights of Compressor as a user tip here.

     

    Good luck.

    I just released a new manual for Compressor 4 that explains what it is and how it works. Understand, not just learn. There are nine screenshots from the book on my website that gives you an idea of what can be done in Compressor.

     

    Hope that helps

    Does your book Edgar, explain how to transode an entire folder of files at one time, or does compressor force you to do one file at a time?

     

    Thank you

    I explain the two options where you can submit multiple files to Compressor in my manual. Here is the short explanation with two screenshots from the book.

     

    1) Create a Droplet and drag all the selected files inside a folder over the Droplet at once:

    2) Once you defined  a default Settings and Destinations in your Preferences, you can drag (one or ) multiple files into an open Batch window and Compressor creates individual Jobs for each file with those Settings and Destination. Now just click the one Submit button and you are on the way

    Excellent Edgar. I appreciate it. I knew about droplets, but not your second solution.

     

    Just checked out all your books and they look wonderful. Will have to get 'em all!

    Edgar, I tried twice to place a paypal order on your site for all your materials. The webapp just spins forever when trying to pay. Any ideas?

    I just tried it and the process worked fine. However, there seems to be some isolated PayPal issues. Email me at GEM(at)DingDingMusic.com and we can solve the problem.

     

    Thanks

    Hi   I have a question.   I went and installed a blu ray burner in my Mac Pro and burned blu ray discs.  I am VERY happy with the quality of the video.    Here is my question/dilemma.  I shot my daughter's school play.  It ran 1 hour and 51 minutes.  It won't of a single layer blu ray -- only a dual.  But as you know, they are quite expensive.  Will Compressor make the video small enough to fit on a single layer disc?  If it does, will it degrade the video quality?  I have Compressor but I cannot understand how to use it.

    Your thoughts would be greatly appreciated.

    Maybe. But probably not.  Try the BluRAy preset. Select the job (not the target and open Job Action. When Job Completes, select Create BluRay Disk. See whether it will let  you select single side. If it doesn't, select target; go into the encoding pane. Move the slider to the left until the message at the bottom indicates it will fit. Give yourself a cushion.

     

    You probably won't see a quality hit. If you do, break it into two disks…part 1 and part 2…

     

    Good luck.

    Video data compression works basically the same as audio data compression when you encode a CD track as mp3. Yes your new file will be smaller. The file size and the quality is a trade off. The higher the compression, the smaller the file size and the lower the quality. At what point you see or hear a quality loss is subjective. There are different algorithms and the newer ones do a really good job of a high file reduction without noticeable quality loss.

     

    Compressor has a BlueRay setting which you can adjust in the Inspector to bring your video file size down to the required size. You can play with it until you find the best compromise.

    Of course, I'll explain the mechanisms on how to do that in great detail in my manual

     

    Hope that helps
