HDTV 1080i compression question

Hello. I have a HDTV 1080i timeline and I want to export it so I can fit it onto a 4x3 DVD using DVD studio pro. What is the best setting to have, in term of best quality and keep it 16x9? Much appreciated.

DVD authoring requires a MPEG 2 video file and a AC3 audio file. You should make thos in Compressor using one of the DVD presets that the running time of your movie fits into. The source for this file should be a self contained movie exported from FCP with Current Settings (same as your Timeline).
In DVD Studio Pro, set up your disc for Letterbox. This finished product will display 16:9 on widescreen TVs and have black bars at the top and bottom on a 4:3 TV.

File Compression Questions/Help Needed

Question, I have just completed an audio presentation project (audio book on CD) for a client (681 mgs) which I now need to have replicated 1500 times over. The problem is my outsourced replicator will only press cd's up to 650 mgs. Therefore, I need to figure out how to compress the presentation just slightly (as to not lose tone quality) to get in onto the disc. (The CD Rom will be played in the car or computer Cd players)
I used the Soundtrack 1.2 to complete the project and also have Quicktime pro, however, I'm not sure what to do and how to change the settings to get the compression correct.
Thanks

Is it something you can simply save as an .aif file, then import it into iTunes and then compress it to mp3 at, say, 256 Kbps? That's pretty good... but if you're looking for better... perhaps an mp2? Not easy to find an mpeg1 layer 2 compression utility, but I use Sound Converter:

Jpeg Compression Question

I would be grateful if someone could help me with this question
I have been working on a series of images taken in Raw , edited in PSE9 and then saved as Jpegs .
The Raw files were all roughly 10Mb each but the maximum size I can save in Jpeg seems to be 1Mb . Is this correct ?
Up to now this has never been an issue as I usually don't get anything printed larger than 5x7 , however I'm hoping to print off some larger poster sized prints and the Online site that I use only accepts Jpegs . Is 10/1 compression the least compression I can do in PSE 9 or am I missing something somewhere ?
Edward

Hi Edward
Normally for prints which are looked at closely you would select a resolution of 240ppi to 300ppi.
But for posters you can go very low, even much lower than 72ppi used for web images. This enables the print size to be vastly increased.
Because posters are viewed from a distance they will still look perfectly acceptable when a ppi of 10-19 is used.

Premiere / Media Encoder Compression Question

Hey all -
Been banging my head on this one for awhile, thought I'd present my problem here - hope I can find a viable solution.
So, I have a 20 minute HD short film that I finished editing in Premiere last month. My sound engineer is working on the film, and requires the video it to be no larger than 100mb so he can work on it... and he needs it exported as a .MOV. My question is, I can't seem to get the file size down to less than 1gb.
What's the best way to compress a 20 minute HD video to a 100mb .mov? My options seem limited to size and 'quality' settings ( no VBR settings for .mov) ... but when I push the quality settings down super low, the video gets seriously degraded and the file size doesn't crunch down that small ...
Desperately need your advice here, friends! Can this be done, and how?
thanks !!!

The problem is that 100MB is hardly getting started with a 20 minute HD video.
There are a number of ways to cut down the file size. The first is to use an efficient codec. If you must use a Quicktime wrapper (.mov) then select H.264 as your codec.
The second is to cut down the bitrate (quality), which you have seen is rather destructive.
Once you have cut the bitrate, then there are ways to make the quality come back up. You could cut the frame rate to about 15. It would make it a bit jerky but since this is for sound and not color or other video related editing, you can cut the bitrate in half when you cut the frames in half and still get something decent.
You can cut the bitrate even more and get good quality if you export a standard definition video instead of HD. Does the audio guy really need HD?
In any case, 100MB is barely anything nowadays. Not for a 20 minute video.
Why does it have to be so small? Can't you post it where it can be downloaded> At around 1GB or so?

File compression question

Question about using the file compression feature within Finder. I understand that when I select multiple files and compress them, it creates a ZIP file with the default name 'archive.zip.' I created a working folder on my desktop and put in about 16 alias of photos that are down in my iPhoto 'originals' folder. When I created the archive.zip, file it was only 2.1 MB (the jpg's varied in size from <1 MB to 3 MB).
I did this with the presumption that by using aliases in my working folder, the compression utility actually compressed the jpg's in the various folders but not the alias pointers.
So, since the archive.zip is only 2.1 MB, what conclusion can I draw? Can the compression really squeeze them down that much?

that's wrong. the compression utility compressed the aliases as it should have. if you want to compress the original images that's what you need to put in that folder, not aliases. but keep in mind that jpegs are already compressed so you'll hardly gain any space by compressing them further.

Weird JPG compression question

Hi,
I am using I am using Windows 7 x64. My camera (Nikon D700) automatically saves copyright data with my name and phone number. I am editing thoose JPEG files from Photoshop CS5 and save them on a HDD with compration ratio 12. For example:
http://dl.dropbox.com/u/26109102/TEST1.jpg
As you can see file size is about 4.67 MB
However, when I right click to file in windows 7 and choose properties and than remove my phone number, file size dramatically reduce at 1.45 MB. Here is a file:
http://dl.dropbox.com/u/26109102/TEST1%20-%20just%20remove%20phone%20number.jpg
So what is the reason of that? Whan I compare both files I can not see the difference in compression. Could you also check it please. Is it a kind of bug?
Thanks in advance.
Koray

The original compression ratio is 66MB/4.5MB = 15 (mental arithmetic).
The final compression ratio is about 66MB/1,45MB = 45.
Such a high compression should be clearly visible, mainly at edges.
But the two images are almost identical. Use image calculation > subtract
and analyze the resulting alpha channel.
a) by histogram
b) by an extremely steep curve.
There are differences, but these are very small.
In my opinion the question is not yet answered. Or is the answer "Microsoft
has improved the standard JPEG compression by factor three"?
I'm using older software, therefore I can't reproduce the OP's tests.
Best regards --Gernot Hoffmann
Edit:
Compression by factor 45 for arbitrary images would deliver really bad results.
The situation here is slightly less critical, because large parts of the image are
almost uniform.
But even if we assume an effective compression by factor 25 for the image parts
with details - the compression artifacts should be visible, in my opinion.
But the aren't. Here we need some clarification.

PAL to NTSC DVD compression questions

Ok,
I have recently finished a dvd in PAL format with about 4.5GB total video once compressed. Now I need to get this into an NTSC version. Is it possible to use Compressor 2 to convert the DVD compressed clips/audio [the ones ready for PAL DVD] into NTSC format ready to build my project in DVDSP? Or do I need my original quicktime clips in PAL format and change them to NTSC in Compressor 2 then make them into NTSC DVD ready clips? Also what is the best setting for NTSC DVD in compressor that will be ok for the size of my final version [4.5GB]. Sorry about these questions but I made the PAl version with compressor 1 and there was far less settings to worry about.

I'm pretty sure you need to go back to your Final Cut source material and re-export via Compressor by selecting 'advanced standards conversion' to get your NTSC files. Then you can import these into DVDSP as NTSC assets.

Flip4 Mac compression question?

Hi everyone!- I have a flip4 mac question
I made a 4 minute video in Final Cut Pro I want to put on an iweb site.
it made a 57 Megabyte Quicktime file so I used "cleaner" to create from that a 6.8 MB WMV video (320X240) and it actually looks "ok"
I am wondering if anyone who has flip4 mac can answer the following questions as I am considering buying the pro version
1) will flip4 mac make a WMV file
2) will flip 4 mac compress it even smaller to say 3-4 MB (57 MB to 3-4 MB)?
3) does flip4 mac make small flash files?
4) Finally in researching the iweb discussions there seems to be allot of posts that says flip4mac crashes iweb has that been fixed?
PS any other program that any one knows of that will convert a QT movie to a small WMV?
Thanks!
Jim

Klaatu,
I use Flip4Mac pro to embed .wmv movie files into my iWeb pages. Here is an example:
http://austinloveministries.org/ALMMediaSite/ALMMediaJesusGodWithUs/DVD%20Lead-I n.html
I have never had a conflict with Flip4Mac Pro and iWeb. I spend hours every week maintaining a very large .wmv media site for my church using Flip Pro to create all of my .wmv movie files and iWeb as my editor. If there were conflict issues, I would have indeed experienced them.
I use iWeb Enhancer to embed the html code to call the Windows Media Player and .wmv files.
The code used to play the embeded .wmv movie in the example above is listed here:
<object id="MediaPlayer" width=580 height=435 classid="CLSID:22D6f312-B0F6-11D0-94AB-0080C74C7E95" standby="Loading Windows Media Player components..." type="application/x-oleobject" codebase="http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab #Version=6,4,7,1112">
<param name="filename" value=”http://71.18.250.184/ALMMediaSite/wmv/JesusGodWithUs/lead out.wmv"> <param name="Showcontrols" value="True"> <param name="autoStart" value="True">
<embed type="application/x-mplayer2" src="http://71.18.250.184/ALMMediaSite/wmv/JesusGodWithUs/lead out.wmv" name="MediaPlayer" width=580 height=435></embed>
</object>
Change the "http://......wmv" strings in the 2nd and 3rd paragraphs to match the server path to the .wmv file you want to play. Also, change height/width measurments to match the size of the iWeb Enhancer box that you create inside the iWeb page. If the sizing measurments are different in the code above from the size of your iWeb Enhancer box, the embedded movie box will not be positioned correctly in the iWeb page.

Compression question for iDVD 6

Hi: I've got a avi file at 1.4 gig that I need to compress onto a single iDVD: can it be done, and if so, how do I do it?
Many thanks

It may not be necessary to import the AVI file into iMovie, but that does often fix some problems.
AVIs, just like .MOV, are containers that can use many different codecs. iDVD likes some better than others, and hates any that have 12 bit audio. Going though iMovie (or QT pro) to convert to DV can fix this sometimes.
So the real questions are:
1) how long in minutes is that AVI file? If less than 2 hours, it should fit on on single layer DVD-R
2)what codecs are used inside that AVI file? If QT can read them, iDVD should be able to use them, unless they are muxed/or 12 bit audio.
If your AVI is less than 2 hours, try just dragging it into iDVD. USe "Save as Disk Image" to test it. If it works, then burn it! If not, then try converting first.
Realize that iDVD will re-compress anything it can read to MPEG2.

QUick compression question - Sorry!

I know this has been discussed a lot. And the general consensus is that - to export an uncompressed movie from FCP I should just File> Export> Quicktime Movie.
Now just as an experiment, I tried using a couple different methods.
I did File> Export> Quicktime Conversion. And then I tried Photo JPG. And I also tried Uncompressed 8bit PAL.
Both of these gave me final Quicktime files bigger than the the normal Export> Quicktime method. And they had higher bitrates.
So my question is: doesn't that mean they are of better quality?

Exporting a movie does not add quality.
You just create a movie file and it has always been stressed that the best quality is the source quality.
When you export a QT movie self contained a perfect copy of each frame originally used is created.
No compression is applied to the copied frames.
Using Export QT conversion add a new conversion step.
No. bigger doesn't mean better.
If I compress a file as MPEG4 it comes bigger in size and possibly lower in quality if compared to H.264.
Cheers,
G.

HDTV Input lag question

im planning on buying an led hdtv for my xbox 360.
But will there be input lag? the hdtv supports 720/1080i/1080p and so does the xbox 360, so there is no input lag, correct?

in other words, can you confirm this?
"Modern game consoles such as the 360 or PS3 don't have this problem since they are all natively HDTV ready supporting 720p, however games in 480i need to be scaled up to 720p and the rendered on the TV, during this can cause a delay, and thus what you control can have a delay on reaction times, such as your character moving a split second later then the actual input itself. This is why there is Game Mode included on certain models of HDTV, to reduce this input lag."

Brbackup compression questions

1) in SAP Note 163490 it mentions that hardware compression can be used
to compress backups to disk. Do i misunderstand and this if for tape compression ?
or if for disk how does it work ?
2) why is a compress_dir (and the space) needed if compression is done with
the unix compress program ? Is it not inline ?
3) if the compress_dir (and the space) is needed, and I write to multiple disks
backup_root_dir = (/backup/dir1, /backup/dir2) does the available space need
to be greater then the largest SINGLE file ?

> 2) why is a compress_dir (and the space) needed if
> compression is done with
> the unix compress program ? Is it not inline ?
Quote from the note: This function is also supported by BRARCHIVE. However, since it does not affect the BRARCHIVE logic there, this is not relevant - so it's not "inline".
The other two question I don't know - maybe someone else does

Quicktime Movie compression question

This is a G5 using 10.5.8 and Final Cut Pro 5.1.4.
I'd like to submit a how-to video to a contest, and the maximum allowable size is 500 MB. My movie is presently three times that size. Is there any way I can compress a QT movie to a smaller size without too much loss of quality, or do I have to just keep editing and chopping away at the video until I get it down to one-third the length it is now? I'm afraid I'll lose too much how-to information if I do that.
I exported the 7 min. 26 sec. video as a QuickTime movie to see what size file it was, and it came out 1.58 Gigabytes.
Under Export, I see that there are also options to export to Compressor or Using QT Conversion. Can anyone tell me how, or where to find out how, to export this video at its present length, but as a smaller file, without losing too much quality? The contest will accept a variety of video formats, but when I converted the project to AVI or MP4 (Using QT Player) the quality got really bad, with a lot of artifacts, halos, etc.
Any advice appreciated.
Tom

Thanks Ben--it looks like it will take care of things. I note that this method shrinks down the QT viewing window and cuts down on the number of frames per second, but the quality isn't reduced too much. By doing that I will be able to send them the full 7.5 minutes of my video, reduced to a file size of about 450 MB, down from 1.58 GB.
This how-to contest asks you to send them your video over the Internet, but I don't know whether they're viewing and judging the videos on a computer or not. If they're not, then they're going to be viewing mine in a pretty small window on whatever monitor or TV they use, but it still beats chopping the video down to practically nothing so that I could send it to them in full quality.
Thanks much for taking the time to help me out.
Best wishes,
Tom

Compressing question

I'm new to final cut pro and compressor. What's the easiest way to compress using final cut pro version 6 and compressor into a quicktime movie?
Thanks!

Aspect Ratio/compression question

I have tried exporting an H.264 file out of FCP using both QT conversion and compressor. The native sequence is DVCPRO HD 720P (16:9 aspect ratio). Each time the file is exported no matter what I set the geometry settings to, it comes out as a 4:3 aspect ratio file. What am I doing wrong?

Hey Casey,
what is the file resolution of your compressed file?
your final file resolution should be 1280x720.
is your image being distorted?
what settings are you using for the export.
a little more information would be greatly appreciated and there are compression gurus that would gladly help you out.
