Best compression for large screen presentation?

I've made a 4 minute movie which is going to be played through a powerbook during a keynote presentation onto a large screen. Any ideas what sort of compression is best for this purpose?

Sorenson, MPEG4, and H.264 are each meant for desktop playback.
Historically, Sorenson is the oldest in this group and H.264 is the newest. Predating Sorenson is Cinepak. Back in the day of QuickTime 2.5, Cinepak was the codec of choice for desktop playback. That, or you would go with a third party hardware based codec like Radius VideoVision or Targa2000.
If your presentation system will have QuickTime 7 installed, then H.264 is probably your best bet. Have you had a chance to download and play any of the HD trailers from the Apple QuickTime Movie Trailers? You can see H.264 in action as well as get more information about the settings used in those files.
H.264 takes a good amount of time to compress, so you'll want to be sure to allow for that when transcoding your video. It offers high image quality with low storage requirements and low bandwidth requirements when the right settings are applied.
What resolution is your source video? In general, try to match your desktop resolution as closely as possible to your video resolution. Also, if viewing the content on a CRT, the refresh rate should be set to a multiple of the frame rate. For example, a refresh rate of 60Hz would be ideal for viewing NTSC material and 50Hz would be ideal for viewing PAL material. Although, from what you've described, you probably won't be concerned with refresh rate, but rather response time (an LCD issue related to the display itself, not display settings).
If your source video is interlaced, be sure to deinterlace it prior to transcoding your movie.
If your source video is DV-NTSC or DV-PAL, be sure to conform the footage for square pixel viewing.
Also, remember that NTSC and PAL are both overscan formats. That is, the outer portion of the frame (typically as little as 4%, but as much as 10%) is scanned over the bevel of the TV frame (in other words, the outer edges are cropped). Depending on your source video, you may want to or need to crop for overscan.

Best compression for exporting large files from iMovie for use in iDVD?

I have a doco that I've made as separate projects too slow to make it all in one project - which I then exported as Quicktime .mov files. When I assembled the .mov files in iDVD I ended up with 4.7GB of material which iDVD flipped out on and crashed.
What would be the best compression to apply to the large .mov files but reduce the overall file sizes by say 10%
Its sometimes taking up to 6 hours to render each project average total screentime per project is about 70 minutes and each project file size ranges from 1 to 6GB...
I feel like I'm a little out of my depth on this one!
Any suggestions for this dilemma?
Thanks
Tony

When I assembled the .mov files in iDVD I ended up with 4.7GB of material which iDVD flipped out on and crashed... Any suggestions for this dilemma?
Not sure if your 4.7GB reference is for the source files or the resulting "muxed" MPEG2/PCM encoded content. In any case a single layer DVD is limited to 4.7 GBs of total content. To be safe, this usually means you are limited to 4.2 to 4.3 GB of encoded movie and/or slideshow content depending on how many and what type of menus you are creating created. Thus, if you are encoding for a single-layer DVD and your project encoded content exceeds the capacity of your DVD, then this would likely explain your problem.
If your project size reference is for the source content being added to your iDVD project, then it is totally irrelevant and you need to concentrate on the total duration of your iDVD and the method of encoding instead of file size. Basically, for a single-layer DVD, only about 60 minutes content can be encoded using the "Best Performance" encode option, 90 minutes using the "High Quality" setting, or 2 hours in the "Professional Quality" encode mode. Thus, if your content duration exceeds the capacity of your encoding mode here, it would likely explain your problem.
In either case, the solution would be to either burn to higher capacity optical media/higher capacity encoding mode or burn your content to multiple DVDs as individual projects at the current media capacity/encoding mode.

Best compression for video with a lot of static text and graphics

Hello! I am producing an instructional DVD and am getting ready to output the files and was wondering what the best compression format would be for me to use.
About 1/3 of the clips consist of video shot in SD with very little movement (guy sitting at a desk talking to the camera.) The rest contains graphics created in After Effects and then imported back into Final Cut. The graphics are primarily text based, and don't change too often. There are some still images as well, but they are static for the most part save for some occasional panning. Oh, and the total length of all the video clips is about 70 minutes.
I would like to compress these videos so as to get the best possible quality in the text. I did a few tests, but the quality in the letters seemed a little worse than I had hoped. Is this just going to be an inevitability I have to live with, or is there a particular setting that would help me out?
Thanks for reading this; any help would be greatly appreciated!
PowerBook G4 Mac OS X (10.4.7) 1.25 GB DDR SDRAM

You know--I really have no idea why I didn't do it that way. I exported uncompressed files from After Effects and then imported them into FCP; some of the files are huuuge, like 60 GB+
I think in the next version of this I will probably just edit in FCP then import it into AE, and then export from there. As it stands though, I've sort of made some changes and done stuff in FCP after importing the clips, so I'd like to just export using Compressor.
So are you saying it's better to export uncompressed from FCP and then import that into Compressor and go from there? I've been just selecting the 'Export Using Compressor' option in FCP and going from there...
Thanks!

BEST COMPRESSION FOR DVD

HI,
I want to find out the BEST compression setting for a FCP project that is 1hr and 41min. I'm burning it to a DVD that is 120min long. It's NOT HD. And it's going to be shown on a wall when it's finished. What are the best settings for this?
Thank you for your help.

#42 - Quick and dirty way to author a DVD
Shane's Stock Answer #42 - David Roth Weiss' Secret Quick and Dirty Way to Author a DVD:
The absolute simplest way to make a DVD using FCP and DVDSP is as follows:
1. Export a QT movie, either a reference file or self contained using current settings.
2. Open DVDSP, select the "graphical" tab and you will see two little monitors, one blue, one green.
3. Select the left blue one and hit delete.
4. Now, select the green one, right click on it and select the top option "first play".
5. Now drag your QT from the browser and drop it on top of the green monitor.
6. Now, for a DVD from an HD source, look to the right side and select the "general tab" in the track editor, and see the Display Mode, and select "16:9 pan-scan."
7. Hit the little black and yellow burn icon at the top of the page and put a a DVD in when prompted. DVDSP will encode and burn your new DVD.
THATS ALL!!!
NOW...if you want a GOOD LOOKING DVD, instead of taking your REF movie into DVD SP, instead take it into Compressor and choose the BEST QUALITY ENCODE (2 pass VBR) that matches your show timing. Then take THAT result into DVD SP and follow the rest of the steps. Except you can choose "16:9 LETTERBOX" instead of PAN & SCAN if you want to see the entire image.

Data Model best Practices for Large Data Models

We are currently rolling out Hyperion IR 11.1.x and are trying to establish best practces for BQYs and how to display these models to our end users.
So far, we have created an OCE file that limits the selectable tables to only those that are within the model.
Then, we created a BQY that brings in the tables to a data model, created metatopics for the main tables and integrated the descriptions via lookups in the meta topics.
This seems to be ok, however, anytime I try to add items to a query, as soon as i add columns from different tables, the app freezes up, hogs a bunch of memory and then closes itself.
Obviously, this isnt' acceptable to be given to our end users like this, so i'm asking for suggestions.
Are there settings I can change to get around this memory sucking issue? Do I need to use a smaller model?
and in general, how are you all deploying this tool to your users? Our users are accustomed to a pre built data model so they can just click and add the fields they want and hit submit. How do I get close to that ideal with this tool?
thanks for any help/advice.

I answered my own question. in the case of the large data model, the tool by default was attempting to calculate every possible join path to get from Table A to Table B (even though there is a direct join between them).
in the data model options, I changed the join setting to use the join path with the least number of topics. This skipped the extraneous steps and allowed me to proceed as normal.
hope this helps anyone else who may bump into this issue.

Best compression for broadcast video

Hi
I need to compress a very short piece for broadcast (5 sec, no audio). What is the best compression to keep it around 25Mb?

It should be. 5 seconds at DV should be 125MB.
If you have to get under 25MB, then I'd suggest getting into h.264. It should give you a very good output at 25MB, though of course not the same as DV.
If you do use a different coded make sure to do it from a QT reference movie so your material doesn't get an extra DV compression.

Best compression for ken burns effect

Hey,
I am doing a 2 minute animation that is all ken burns effect. The size is 720 x 1280. On the images that have a lot of detail like brickwork, there is a noticeable pop where you can see compression for a few frames and then it clears up.

Yes. I have an idea. Don't do that.
AE is definitely not the best tool for making an H.264. Render an intermediate file out of AE (lossless or nearly lossless, such as Quicktime with the PNG codec, Quicktime with the PhotoJPEG codec, Cineform, or DNxHD). Then use the Adobe Media Encoder to make the H.264. Use multipass compression. Adjust the keyframe distance, etc. The cool thing is that you won't have to render your AE comp over and over again for each time you need to test a different setting in your compression. You're just running off of the already rendered intermediate file.

Best compression for web?

If client's need a video (usually under 5min) for a website, what is the best compression setting for that coming out of FCP (usually 960x720)? I usually do h.264 680x480...

Stuttering and difficultly playing are bandwidth issues. Your bitrate is too high for their limited playback capabilities. when your reduce the bitrate, you will reduce the image quality. This is why we tell newbies at this to ask what the playback limitations are for their client's servers.

Best compression for video on web

i have a website (made with iWeb and published on .mac) and I have a few pages of video clips. They vary in length from 30 seconds to about 6 minutes or so.
What is the best compression to use? I've been using H.264 and the sizes of the files go from about 7Mb up to 12Mb - it just takes such a long time to load online.
How can I create video that looks good but loads quickly? For example, how do movie sites create their trailers for online use? They look great and you can see that the progress bar on the video loads up really quickly, meaning that the video start playing almost as soon as it loads.
With my site, it takes a good minute or two before it starts to play. Any ideas?

*how do movie sites create their trailers*
No offence meant, not on iMacs. They have more expensive hardware for this.
The subject of video compression for web has been discussed on this and adjacent fora many times and I suggest you use the search function. Also, googling would be a good idea, especially words like Brian Gary who is the Compressor guru.
The topic is too complex for a quick post. I apologize for not having the time to type more.

Best codec for green screen in FCP or Motion

First--I tried to search for posts on this topic, but I swear I cannot figure out how to search -the discussion forums- on this site. Anyone want to tell me what I'm missing?
My main question is about codecs for keying green screen in FCP. I have always just worked with DV but it does not key very well. I am about to go into a project that involves editing 25-30 hours of studio footage down into about 5 hours of finished product, all of which is going to be shot against a green screen. We're using high-quality non-digital NTSC cameras for the shoot and encoding to hard drive, which gives us the option of using a different codec. Since we need to capture so much footage (various takes, camera angles, etc), I don't have the budget for the hard drive space required to capture it all uncompressed, but I'm looking for something better than DV.
I've seen some people are using DVCPRO 50 for green screen work, and I think I could get all the footage onto a single 1TB hard drive in that format.
Is DVCPRO 50 significantly better than DV for green screen? Is there another codec which would be better to use with FCP/Motion, but still keep my data under 10MB/sec?

Is the difference between 4:1:1 and 4:2:2 some part of what causes the blockiness in DV?
No...the DV compression is what causes the blockiness of DV. It is compressed 5:1, and how it is compressed is the cause of the compression. Mind you, if you shoot to DV tape, then capturing that as DVCPRO 50 will not get rid of the blockiness. that is there when you record to tape. It will convert the footage from 4:1:1 to a 4:2:2 color space for better color control when keying and color correcting. But much of the color information is already lost when you shoot to DV tape. Capturing as DV50 will certainly help, however...and be TONS better than keying as straight DV.

What is the best compression for HD footage for online use?

I have a sequence with the following specs:
HD (960x720) (16:9), HD 960x720 aspect ratio, DVCPRO HD 720p60 compressor and need to output a 300x250 file for an online banner.
Was wondering what you think the best looking compression would be for me to use plus whats the best way for me to keep the aspect ratio consistent within the new dimensions.
Any help would be much appreciated! thanks!

While a lot of people have Flash, not all of them have the latest version (or even the previous version). Newer versions of the Flash Player support better video codecs. I still encounter people (corporations) that are still only using Flash Player 7…

Best compression for Beta SP

Hello,
I need to export my film so I can take it someplace where I can put it on Beta SP. The FCP project is
HD1080 16:9.
What is the best compression method that will bring the best image to the Beta?
Thanks a lot.

No you shouldn't make it m2v .That's for DVD authoring.
You can't dump m2v to BETA from a fcp timeline.
a. export quicktime movie with current settings from fcp
b. drag movie in compressor
c. Choose preset Quicktime->Format->10 bit uncompressed
d. Choose proper frame size

Best settings for Green Screen Video with Canon Mark iii

HI
What are the ideal camera settings for Green screen video.
Iso?
aperature?
Depth of field settings (best to have the green screen a bit out of focus?)
Any other camera settings would be helpful.
Thanks
Rowby

Hi Rowby!
Thanks so much for writing in about green screen shooting with the EOS 5D Mark III camera. Green screen shooting can come down to some crucial elements and how well you handle the camera and the lighting.
Arguably the most important thing is to have excellent lighting on the screen. Without this, the keys used to replace the green screen will not be accurate. So hopefully you have a good set of lights you will be using to actually light the physical screen.
With regards to ISO, shoot as low as possible. We suggest that you stick in the ISO 200-400 range where possible. With good, high key, proper lighting on the screen this shouldn't be an issue.
Aperture should actually be in the higher end of the range, you would want to stick to apertures around f/8 and above. Again, with adequate lighting this shouldn't be out of reach. This is so the green screen is more in focus, versus having it out of focus, which would not yield successful results.
Use an appropriate lens to the subject, for example if you are doing wide shots- use only the focal length needed for the shoot and no wider. For head shots, close ups- use a lens that will get you close.
Following these suggestions should give you some pretty good results. Remember, if this is your first attempt don't be discouraged, green screen shooting can be difficult to accomplish.
We wish you the best of luck in your endeavor!

Best compression for IDVD

I am taking a slide show made in Iphoto and saving it. Then I open it in Express and and add a sound track to it and then save it as a quicktime to be brought into IDVD.
What is the best setting for that quicktime movie because it doesn't look so good when i bring it into idvd.........? i just am saving it as a quicktime looking for the fastest processing... but best quality is important too....
can i dvd import mpeg4? I was hoping to save it as dv but that seems to be a long export time... speed is important
I also could save it as an mpeg-2 and then go through studio pro but i want something quick for the family christmas card which is a dvd....
thanks.....

Test results for you Martin (and anyone else!).
I used 10 good quality jpeg slides (2560x1920) and didn't bother to downsample them.
Imported them into FCE at 3 seconds each for a running time of 30 seconds.
This slideshow was converted to a QT Movie and put into iDVD.
I then made another slideshow in iDVD using the original jpegs.
The DVD-RW was burned using Best Quality. The whole exercise took about 20 minutes.
The DVD was viewed on both the CRT monitor of my eMac and a large 28"(4x3) CRT TV (using a DVD player).
Sharpness-wise I could not detect any difference (between the 2 slideshows).
However the FCE slideshow did exhibit more interlace flicker/aliasing on certain slides. (I hadn't got a TV hooked up during the FCE phase or used a deinterlace filter).
The results are neither scientific nor conclusive but they do suggest that we may be worrying too much about the techniques we use.
