Compression Time: 90 vs. 120 vs. 150

Hope this is a simple question:
When using compressor to compress video for DVD, can anyone answer the question as to whether different compression settings take longer?
Not asking about single encode vs. best quality, but specifically:
Does it take the same amount of time to compress video at DVD 90 minutes vs. DVD 120 minutes or DVD 150 minutes, or will one take longer than the other and if so, which takes longer?
thanks

Assuming the same length of material the 90 minute setting should be quicker.

Video compression times

I am considering purchasing a Macbook Pro,
I'm a mobile user who also does a lot of video work (mostly compressing into many differenct formats and resolutions for each video.)
I would like to get some feedback from users about DV compression times using softwares like Final Cut Pro, and After Effects going using .h264 and going into formats like wmv and mov mainly.
Any info is appreciated, as this will be my ultimate deciding factor on what to buy.

There are 2 things, in particular, that you're doing 'wrong,' so to speak.
One is lowering the data rate. With h.264 compression, a lower data rate means your system has to work extra hard crunch the information down. Since the iPod/iPhone setting is multi-pass by default, that means more passes (and longer encoding times) for a 1100 kbps encode vs. a 1500 kbps encode.
Second, iPods & iPhones have a limited frame rate spectrum. I've not seen anything less than 23.98fps or more than 30fps work correctly.
As Michael mentioned already, exporting directly to Compressor takes a tremendous amount of time, about 4x to 6x as long as dropping in a QT movie into Compressor. It's sometimes worth it because the compression quality is superior, but you don't seem to have the luxury of time.
In terms of immediate solutions, if you simply need to get some compressed quick, use the default setting but uncheck the multi-pass box.
For a potentially more complete solution, please detail what your sequence settings (frame size, frame rate, etc) are in FCP and what frame size you're attempting to export to (iPhone @ 480px wide? or iPod at @ 640px wide). Or is your issue more about data rate? Do you need the 30 min file to be 25 MB, for example?

I have to do the math for compression time?

Compressing HDV to DVD 120 best quality.
Compressor processing tells me what frame it's rendering. It's been 4 hours and I need to know when this will be done. What happened the the calculation time bar? It just went from 145,000 and started over. Does that mean it's on it's second pass, or is it just gonna keep looping all day. I hate to stop it and lose all that time.

There is a time bar that was collapsed - hidden from me.

Compression Times

Does it really take 13 hours to encode a 1 hour 16 minute video?
Using Compressor 2.0.1 default 120 minute high quality setting. I have been encoding for 2 hours and 25 minutes, the encode is 72% done and it says it will take an additional 10 hours 52 minutes!!!!
That is slower than my dead grandma.
Is there a faster method than compression?
I have tried using EyeTV 200 and I get a "video bit rate too high" build killer dialogue box. (encode from EyeTV to DVDSP at 120 minute rate)
What should I try next?
Thanks,
C.J.

It obviously depends upon the speed of your computer and the preset you use. On my 800MHz PowerBook I get about a 16 to 1 ratio for a two-pass best quality MPEG-2 preset when I export from FCP to Compressor v2. However, for a one-pass good quality preset I get under 2 to 1 (one hour of video compressed in under two hours) when I submit the job directly to Compressor.
I've seen a few recent reports from dual G5 users who have reported real-time two-pass MPEG-2 compression and much better than real-time for one-pass jobs.

90 min/120 min/ 150 min?

Surely I am missing something.
When I go to Compressor to deal with a movie and go to the popup menu with compression choices I am toally confounded as to which to choose. And I am finding no guidlines in Apple's documents. Where does one go to make informed decisions?
But the overriding confusion is caused by the multiple choices differentiated only by "90 minutes" "120 minutes" or "150 minutes" etc. Can someone please explain to me what they're talking about and why I would choose one over the others?
I'd really appreciate it

Alan:
Take breath!
On each preset you'll find a short description in the Inspector window:
DVD: Best Quality 90 minutes: Fits up to 90 minutes of video with Dolby Digital audio at 192 Kbps or 60 minutes with AIFF audio on a DVD-5.
DVD: Best Quality 120 minutes: Fits 120 minutes of video with Dolby Digital at 192 Kbps or 90 minutes with AIFF on a DVD-5.
DVD: Best Quality 150 minutes: Fits up to 150 minutes of video with Dolby Digital audio at 192 Kbps or 120 minutes with AIFF audio on a DVD-5.
The key factor to choose the right preset is the lenght in minutes of video you want to place in your DVD.
If you deep in the Inspector summary for each preset you'll find the difference between them is in the data rate (bitrate: to fit more minutes of video you must use a lower data rate, what means a lower video quality.
I hope it helps !

Compression Time - Conservation Film

Hello - I'm compressing a 40 minute movie shot in HDV to standard DVD format. It's been 3 hours and has been at 52% forever now and says 42 hours remaining. I wanted to post my specs to see if anyone out there could tell me if it was worth waiting that long so long as I did everything else right. Or maybe have a better option???
I first exported the whole movie to QT (7GB) and then dropped in Compressor.
Used One Pass, Best Quality 90 minutes 16:9, Field Dominance - Progressive, Moved the CBR to 8.9 mbps, Frame Controls - Better, Motion Adaptive and changed my destination to my eSata drive which is where the movie is stored. The QT I drug in is from the desktop, however.
I have a PowerMac G5, 2.0Ghz, 3 GB Ram - with 45GB of space on my PowerMac and a Lacie TwoBig.
Thanks as I have just missed my deadline today and really need to get it out by Monday now. Should I wait 42 hours (or does that go down later as is often seen with FCP render files?)
Mahalos and Aloha in advance
Bryce

Compression and decompression are extremely processor intensive tasks, with every pixel of every frame needing to be separately processed ... and depending on the codec this is complicated even further with advanced analysis requiring comparison between equivalent pixels in preceding and forthcoming frames, sometime using multiple reference frames, you can't even begin to imagine how complicated a task this is and it has to be done to the source file depending on its original codec (ie it needs to be decompressed) and the target file depending on that chosen target codec ... but that's what computers are good for so no worries, right? Wrong. Computer processors are optimized for general computing tasks, not codec specific compression and decompression tasks, so whilst using a computer is obviously a lot quicker than doing it by hand, it's still is going to take a long time. How long? Depends on how tricky the source and target codecs are, and how clever your computer is.
Hope it helps

Compression time

i finished editting an HD project on final cut pro 7. i'm using Compressor to then imported into DVD Studio Pro. the project is 32 minutes long and i'm using HD DVD: H264 60 Minutes. at this rate, the project will be compressed in 24 hours. i started compressing it at 3am and its halfway done 12 hours later. just wanted to know is this how long it takes or am i doing something wrong? or should i have used something else?

Start with the 90 min best preset in Compressor.
If you see issues with the down-convert you could turn on the frame controls in Compressor. If you set these all to best it will take a very long time to render.
I have found the preset to be consistently inconsistent with HD to SD. Sometimes it works and sometimes it doesn't. In a pinch with shorter programs we have rolled off a SD master through our Kona card / re-captured the SD master and then sent that to Compressor.
The only other option would be a hardware converter.

Exporting to Quicktime compressing time grows

Greetings,
I'm trying to export to Quicktime with expert settings to get a file size larger than CDROM but smaller than Full Quality (which is a whopping 19 GB file). When exporting and compressing the movie, the time remaining keeps growing and growing while the progress bar seems to hang about 1/5 of the way through. I've tried this on a couple of different computers and to different hard drives. I even tried exporting to the CDROM option with the same effect.

"Full Quality" will be a .dv file (no reduction from your source file).
You don't want that setting unless you need to move the Project to a QuickTime format (to continue editing or to bring back to iMovie).
You will need to use the "Expert Settings" dialog (avoiding the preset options) but you must first know how your file will be viewed.
Are your trying to email? Send the file to a Web page? Display the file on a LAN?
How long in time is your video? Where will it be viewed?
Read my "Profile" (click on my screen name) for more options.

Extremely long compression time

I am trying to compress a 6 minute video into a quicktime movie. It starts out saying it will only take 3 minutes to share. Then it quickly moves up to 17 minutes before coming to a halt.
Anybody have any ideas on what I am doing wrong or is this common? On previous videos this has never happened. I've tried doing a different video and it is also taking an extremely long time to compress.
Thanks for the help

I think possibly it could have something to do with my video settings. I don't know much about video settings.
We are producing these videos that range from 7-30min from a video camera. We don't need audio (already took that out) and we don't need the best of quality on the video. It obviously needs to be decent enough to see what is going on without straining, but beyond that I don't need much.
Does anybody have any suggestions on the type of video settings I could use in the expert settings? I believe iMovie is trying to compress much more information than I really need. Thanks for the help.

Compressing time of multiple layers

sorry this is so basic...how can I select multiple layers (and their keyframes) which may span, say, 2 minutes, and reduce this to say 1 minute for all the layers, compressing all the keyframes closer together, etc. Thanks

Your question makes it seem that you're trying to compress the time of the layers themselves (i.e., make the video footage run faster). If that's true, then you could just precompose the layers and then apply time remapping (or time stretching) to the precomposition layer.
If you're just trying to compress the keyframes, then the answer is different. You can contract a group of keyframes in layer bar mode or do it in the Graph Editor.

Compressor not compressing time line

Let's see if someone can help , since the last update to 6.03 from 6,02 compressor will not compress anything submitted from final cut pro. When submitting final cut created the tab with the long number but as soon compressor is fully loaded the tab in final cut disappeared and when hit submit in compressor compressor just sits and nothing happens. I have tried to export as quick time first and put that in compressor and that works and sometimes does not work
any idea

thanks for getting back but unfortunatley that does not work either. Again I bring the self contained file in and do all the steps to compress and compressor just sits there nothing happens.

FYI--Compressing times of a dual 450 vs dual 1.25 vs Quad

Just got my quad and after some hoops to jump thru I have fcp 4.5/compressor 1.2 running fine now.....
Now these times are not 100% accurate....off by a few minutes here and there but this is what i've got from going from two g4's dual 450 and dual 1.25 to a G5 Quad.....
This project is 1 hour and 40 minutes with a fair bit of colour correction, a third of it time remapped, and a third of it with a widescreen matte...
dual 450 - just the video compress --approx. 15 hours
dual 1.25 - just video --approx. 10 hours
Quad - just video compress---under 1 hour and 30 minutes....
All I have to say is holy crap batman!!
For me getting the quad now certainly makes a lot of financial sense as I will be able to finish projects a lot faster. I have a back log of about a dozen projects. Can now ship off my slowest mac to a friend who can work for me as well.....:)
The Upgrade is coming in the next week or two and I should see a bit of a difference there as well.....
WOW WOW WOW.......

I put it in my Startup Items, and after a couple of clicks,
and my admin password, its up and runs fine.
My only probelm is I have a bit of an audio problem,
but I've created a work around for that, and all is well

Compressing Time Machine backup folder and burning to DVD

Can I compress the backup folder and burn to a DVD disc?
Most people seem to assume that an external hard drive won't fail and so keeping all files backed up to it is a good thing. Surprise - external HDDs fail also.
I'd really like to have compressed back ups on a DVD in order to have 3 locations with my files.

It would have to be a pretty small backup to fit on a DVD. You won't likely find too much benefit from compressing the data because much of it is in binary form that is most likely not going to reduce much if at all.
A single DL DVD can hold 8 GBs. If you have just OS X installed that will require 16 GBs less whatever you may save compressing the data. Personally, I would not risk compressing the data since that could prove just as problematic or more so than keeping it on a hard drive. Furthermore, if you want more than 5 years storage life out of the DVDs, then you have to avoid the stuff they sell at places like Office Depot which have a relatively short shelf life.
If you need to use more than one DVD, then you need a backup utility designed to span a backup across multiple media. Your choices are somewhat limited: Retrospect, Apple's Backup (requires a .Mac account to download and use,) and possible Tri-Backup (but I am not sure about it.)
Or you can buy several hard drives of suitable size, make multiple backup copies to each drive, store one in a vault off-site. Rotate your weekly and monthly backups to the other drives and once every quarter rotate the off-site drive. The chance of all the drives failing at once is pretty small.

IDVD Burn Compression times?

I am new to iDVD and burning DVD's.
Using iMovie 5 (DV-NTSC fromat preference)
Does anyone know what the general rule is for compressiing a project in iDVD?
I have read that you should not try to fit more then an hour onto the DVD.
Does that mean if I have 2 hours (Per the iMovie project counter) that is will compress in iDVD down to an hour?
Or does that mean if iMovie shows an hour , by the counter, that is what you should do? I think my iMovie project is 30GB so I need to split it up I assume.
If a DVD will hold 4.7 GB does that mean my project cannot be more then 8GB for instance? Just as an example.
I have done much reading on this but it isn't clear to me. I could experiment and just start burning discs and see what really will fit.
I know different formats compress differently but I want to get an idea because my project currently is 2 hours 17 minutes.
From what I have read is seems that Toast may do a better job of burning to a DVD also (Better compression).
I do have a R-DL capability on my iMac so does that mean I can get two hours on Double Layer DVD?
Please excuse my ignorance on this subject.
I hope I don't sound too stupid.
LargeAl

I hope I don't sound too stupid.
no, you don't.
compression is some kind of "magic", codecs, bitrates, whatever...
so, for convenience&simplicity, Apple says:
iDVD can process files up to 120minutes
ok, a little less, depending on how excessive you make use of menus, buttons, music in the dvd's menu....
in case you're interested:
iMovie uses, as your camcorder, a video compressor called "dv", that is ~13GB per hour, a videoDVD has a different compressor, called "mpeg2" making 2h fit on a 4.4GB disk... what iDVD does, it converts your video... automatically...
the quality differs just of [u[length[> of the project! you get the best results with projects <60 minutes, but 120min looks good too...
for experimenting, I recommend usage of dvd-rw media... reusable
