Video Compression for idisk, Stuffit?

I am trying to transfer large videos to a friend via my idisk. If I take these files and compress them using the Stuffit program, will this make a safe and user friendly transfer?
I only have about 1 gig of space on the idisk to use, and my current video files are much larger than that.
Thank you.

How large are they and in what format (what codec)? Video and a lot of photo files are compressed already and Stuffit or Zip won't make them smaller, in some cases they get bigger.
If they are raw DV or something with a really high bitrate the other tip is to reencode them to H264 which can really compres them to a fraction of their former size but you have to give some idea of what you are starting with.

Video compression for iPad?

We use Final Cut Pro 7 - and frequently compress our HD videos we make using Compressor. We use high end HD cameras, etc., and have beautiful results when compressing at, say 20 - 30mbs for display on HD monitors and televisions. We know how to compress for iPod and Apple TV, and various web sizes . . . but what parameters should we be using for the iPad?
I've read it plays up to 2.5mbs??
I hope I'm WRONG, because with fast moving subjects, you'll see a lot of pixelation at that low data rate.
I looked in the Compressor templates, but don't see one for iPad. Anyone know what settings we should be using? Or what's the highest data rate an iPad will play?
Thanks,
Larry

Here's what the specs say is supported:
H.264 video up to 720p, 30 frames per second, Main Profile level 3.1 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats
MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file format
Motion JPEG (M-JPEG) up to 35 Mbps, 1280 by 720 pixels, 30 frames per second, audio in ulaw, PCM stereo audio in .avi file format
My unit hasn't arrived yet for me to do any testing.

HD video compressed for the web

I was doing some testing trying to figure out the best way to compress the HD video I get from the Sony XDCAM HD for the web (streaming). I shoot in HD (1080/30P) because it's needed for our videos. The web streaming is secondary.
I would prefer to make the web videos .flv because it works best and most easily cross-platform. In the real world, the majority of users have Windows PCs, which made me hesitant to use h.264 (.m4v) because it probably would require the average user to download things they may not wan to. Nonetheless, it has to be viewable on all computers in all browers.
So, I took three 10 second clips of steady camera video with audio from the camera that I used in all tests. I will refer to them by clip number...
Clip 1: 30P 16:9 High quality, 10sec=45mb
Clip 2: 30P 16:9 Low Quality, 10sec=24mb
Clip 3: 60i 16:9 High Quality, 10sec=45mb
First I tested making FLV is Adobe CS3 Encoder using the High Quality (700) setting.
Test 1 used size 848x480 (16:9)
Clip 1: 1.3mb
Clip 2: 1.1mb
Clip 3: 1.2mb
Comments: Looked very crisp, audio was clean, slightly darker image than original on default settings
Test 2 used size 480x270 (16:9)
Clip 1: 1.2mb
Clip 2: 1.1mb
Clip 3: 1.1mb
Comments: Looked very crisp, audio was clean, slightly darker image than original on default settings
Next, I tested making .m4v using the h.264 iPod settings in Compressor.
Test 1 used size 640x370.
Clip 1: 240kb
Clip 2: 1440kb
Clip 3: 204kb
Comments: Image wasn't quite as clean as the Flash files, but still good. Much lighter/brighter than the Flash files also. Low Quality HD video had high file size... why? I don't know, but I don't shoot on LQ for things anyway.
Test 2 used size 320x180.
Clip 1: 160kb
Clip 2: 865kb
Clip 3: 865kb
Comments: Image wasn't quite as clean as the Flash files, but still good. Much lighter/brighter than the Flash files also. Low Quality HD video had high file size... also the 60i file...why? I don't know.
In conclusion, I'm lucky that I shoot 30P since it worked well in all areas. The h264 codec provides a much smaller file size than Flash, with a good image. Amazing considering we started with a 45MB clip. What are the standards for aspect ratios for putting 16:9 video on the web? I haven't heard much set in stone like you have for 4:3 video. Nonetheless, the 640x360 or 480x270 seem to be a nice size for most uses.
I have heard that in Flash 9 you can chance the m4v extension to flv and it will work. IF that is true, that would be great because now my concern is that a base Windows PC cannot play these .m4v images without plugins/codecs. I suppose right now its a tradeoff between smaller file size/less compatibility with h264 or larger file size, great compatibility with Flash.
Any comments or suggestions to help out would be great. I typed this fast so forgive me if I left out any important info.

Hi APPLE27:
One comment from your post that immediately caught my attention was this, "Nonetheless, it has to be viewable on all computers in all browsers."
Unfortunately, it is unrealistic to expect one digital video file to be viewable on "all computers in all browsers" as there are simply too may variations in both hardware and software.
A common approach when offering digital video is to provide two formats to choose from and then within each of those two formats a few versions of the video for different bandwidths.
For example, a web site might offer Video for Windows and QuickTime. For each of these, there would be a low bandwidth Video for Windows file and QuickTime file and a high bandwidth Video for Windows file and QuickTime file (four files total). Of course, there's also Flash Video, Real Video, MPEG1, and so on.
For better or worse, YouTube.com has allowed video content creators the realistic expectation of creating a digital video file that is viewable on "most computers". But, the video is unavoidably tied to that web site.
When it comes to online distribution of video, it's still very open ended.
Also, computers are not all that's out there. Mobile devices are a huge market and you'd be hard pressed to create a single digital video file that will play on all mobile devices (iPhone, iPod Touch, Palm Treo, Sony PSP, etc.) either from local storage or from a mobile browser.
QuickTime offers a solution for creating a referencing movie - one file that links to other digital video files, but it too is imperfect at best when it comes to reaching the broadest audience possible.
With my few comments here, I'm just scratching the surface. But, it all starts where you are right now: caring about the image quality when exporting from your edited master.

Video compression for web. H264 codec.

Hello to everyone!
I would be gratefull If someone can help me with some advice on the following matter:
Who can I compress a video which is shot with dslr camera, at 640x424p, 25fps, so that 20 seconds of video do not exceed 1mb.
The final video has to be 512pixels in height and 340 in width, good quality under 1mb.
I usually export this kind of web files using h264. For this job I modified the biterates so that the video does not exceed 1mb but all resulted in poor quality.
The satisfactory quality of the video is reached only after 4mbs(biterate/vbr pass2), in this case the filesize is over 5mb so again no good.
Please help?

And another thing I noticed in Premiere: I usually do a small edit of about 20 seconds from 3-4 clips. Well, this time I compressed the three clips before editing them in premiere. I used the h.264 encoder I talked about and it reduced my filesize to half for each of them(no visible quality loss). Now I imported the 3 files(reduced) in Premiere and the 20 seconds of editing still export as the same big size it was before encoding and reducing the clips. More interresting is that all three clips together have about a minute of footage and they get pretty close to the filesize that the 20 second export video has.
I did another experiment and imported one video file in Premiere and without modifing the content, i wanted to export it to see what happens with the filesize after entering and exporting with premiere. The export was bigger in filesize and lower in quality. One thing changed though: I imported a mov and exported an mp4. So how come my dslr camera exports such good quality videos with such small file size. Is mov better than mp4? If the software camera did such great job compressing the videos, why can't I find a computer software that does the same?
I appreciate your time!
Thank you!

HDV orginial video compress for SD DVD steps, I need

I read some on this forum and not sure what I suppose to do to compress from FCP to SD DVD. Can you tell me what is the steps on compressor. It will be show on theatre screen (not hollywood type).
FCP compression setting?
Compressor setting?

You could try duplicating that 90 minute preset so you can make a few adjustments. One of the settings I modify in my m2v presets is in the Frame Controls: Resizing Control: Deinterlace. I have that set to Better or Best, depending on the video. I also set the Output Fields: to Progressive. This seems to work well for my DVDs even when down converting from HD.

Best Video Compression for the web???

I have read a number of discussions about which codec to use to compress video for the web and I’ve done my own tests and bar the longer encode time, which is not a problem to me, H.264 seems to come out as the best. I can get a superb quality, small enough for a quick download EXCEPT… this website needs to be friendly to the PC community.
What do you all suggest I do?
Go with lower quality MPEG-4 or Sorenson 3 and have my work look “not so good” or use awesome H.264 and provide a link to download the codec, which busy PC people will probably not bother to do.
This is my dilemma.
Thanks in advance for any advice.

I love the results I get when using H.264. Even low data rate files look good (even when I display them double size).
But it requires your page visitors have QuickTime 7 installed to view your QT files.
QuickTime 7 is nearly a year old and most of your Mac viewers will have it installed. It is also "bundled" with the iTunes software download that many PC users have installed.
H.264 is the only codec that requires version 7. Any other choice can be played using older versions of QuickTime.
As much as I like H.264 its installed viewer base doesn't reflect the visitors system settings for Web work. If your crowd is savvy to QuickTime they will not mind the download to upgrade. If you use tracking software on your visitors you'll be able to see if they hang around for the download.
MPEG-4 may be a better Web use choice.

10 Minute video compressed for web streaming help

Hi, I have to get some 10 minute videos online and I can't seem to get them smaller than 60 MB. Right now they are great quality H.264 files but they are all 111 MB. Does anyone know how to get these files to an acceptable file size for the web?
I have to keep the size of the video at 570x320.
Thanks.

I'd have to agree with Dave on this one. Your movie dimensions are the biggest hang up.
How about an old Web trick that works nice with H.264 files? Half size.
Using export via QuickTime at the settings that made the 11MB file but set the dimensions scaled half of your intended size.
I know. You want a big display in the Web page. Here's how to do it.
In the html code are special tags used by the QuickTime browser plug-in. One (rarely used) is scale="tofit".
In the embed tag add scale="tofit" and in the object tag use param name="scale" value="tofit"
In each (object and embed) tag are dimensions used in the source file. Change these values to your desired size (double them).
Bingo! Big display of a smaller file sized movie. Your viewers will not know what hit them.

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.

Using BlackMagic Intensity Pro Video Compression card with FCP in a MacPro

BlackMagic is offering the Intensity Pro card that they claim is enhancing the quality of video compression for better results than software driven compression, even with Standard DV in addition to HDV, and at a surprisingly cheap cost (less than $300).
http://www.h-digital.com.au/hardware/hardwareview.asp?id=152
As someone used such hardware driven compression card in a MacPro ?
Does-it really help making better quality DVDs?
If not are there better hardware driven compression card?

7-8 years ago, we said that analog video was at the low end and DV was at the high end.
Uh, DV was NEVER on the high end. Digibeta and Beta were analog, and were HIGHER end than DV. Just because it was digital doesn't mean it was better. DV is compressed 5:1 and has 4:1:1 color sampling. Beta was 4:2:2 and better than DV...and Digibeta was and still is the high end SD format. DVCPRO 50 a close second. No...DV came in on the low end...like HDV comes in on the low end of the HD spectrum.
If this Intensity card does not help to get better compression than software driven compression, is there another card which can do so ?
Well, I answered this, but you must have missed my answer, so I will bold it for you: *THERE IS NO CARD OUT THERE FOR THE MAC THAT WILL AID IN DVD COMPRESSION.* I don't know about the PC side, so I make the statement to include MAC only. There are several hardware solutions for encoding DVDs that distributors use when making the theatrical DVDs like OCEANS 13...but those are separate hardware encoders. And no, again, those encoders are not available on a Mac.
What I mean at the end is to find ways to have higher quality DVDs than when using software such as Compressor. Do you follow me ?
I follow you....you aren't following me. Since I am an editor and not a distributor, I don't know what those solutions are. They exist outside of the editing world, so you have to GOOGLE this or look elsewhere. Needless to say, the Intensity does not aid in this. No capture card does. That is not what they are designed for. They are designed to capture non-firewire formats and to output to non-firewire formats...not to aid in DVD compression.

HD Video Compression Issue

I'm looking for information on weather or not Flash CS5 (I currently use Flash 8) can handle HD video compression for web streaming. I have tried this using Flash 8 but only get an error, however as you might expect Flash 8 does compress standard definition video for web streaming. I have done research on the internet, but really haven't come up with a definite answer except to find references to using Sorenson Squeeze or Final Cut Pro, but I don't want to pay for another Video editing program (currently using Final Cut Express) if I can upgrade Flash and get the HD compression feature.
Any help and advise would be apreciated. Thanks

If you're publishing for Flash 9 or higher (which CS5 can do) then you can publish to H.246. I would think that FCE could do that.
Normally I would say that you could download a trial and see for yourself. But I think because 5.5 has been announced Adobe isn't offering a trial for the next couple of weeks. There were a lot of improvement to the Flash video encoder in CS5. That being said if you really want to do a lot of intense video work you should get the best tools.

I deleted all my photos and videos and then delete the deleted files but the photo app is still taking up 12 GB of space and I have no room for new stuff. How can I clear the memory space used by my deleted videos and photos?

What is the best compression for HDV 1080i60 video to be played on iTunes?

Hello guys,
I would like to make an HDV video podcast for iTunes and possibly for other podcasting sites. My source format is HVD 1080i60, each episode would be about 10 minutes long. So I am wondering what format, compression and settings work best while keeping reasonable quality.
Thank you for any tip or advise.

One thing I forgot to mention: the Apple TV setting H.264 file won't play on an iPod. If you did need an iPod/iPhone compatible version, then the export setting to use would be Movie to iPod. This will make a 640x360 file. The full explanation of the differences between iPod and Apple TV formats is at http://www.apple.com/itunes/store/podcaststechspecs.html#formattingvideo

Audio and video compression preferences for export to DVDSP

Hi,
I have a few questions here. The first is regarding the internal use of compressor by DVD Studio Pro. It is my understanding from (limited experience with) past projects that quicktime movie files are automatically compressed to an mpeg2 format when imported into DVDSP. To what extent do I have control over the level of compression, and are the default mpegs that were made optimal quality? Where can I check this?
My second question is regarding compression of audio files. Whereas my video files were automatically compressed, I am not so sure about the audio. I was forced to compress the audio down to Dolby2 separately using the external compressor program, in order not to exceed the bitrate on my last project. Was this just a question of one or the other (video/audio) needing further compression than the default amount, or is there more to this issue?
I live and work with video in Europe, where I have recently been told that optimal audio is mp3? 4? rather than Dolby 5.1? Is this correct, and how much more space does dolby 5.1 take than dolby2? How significant an issue is this when making dvd's for musicians?
Lastly, can someone recommend the best quality audio-video compression solution for a dvd containing approx 40 minutes of audio and video footage for use in europe?? or explain how I might go about finding this out for myself?
Thanks a lot, and I look forward to reading your comments.

Settings for DVDSP's internal encoder can be adjusted in DVDSP preferences. Press Command-, - that's the Apply and the comma keys - to bring those up, then select the Encoder tab. In your case, make sure you adjust the settings for SD DVD (and not HD-DVD). You will also be able to specify whether to encode in the background (basically, as soon as you import your file) or encode on build, at the bottom of that tab.

I can't confess to have read any of your previous threads, but if you exceeded bit rate, that is a common reason to need to use Dolby compression for your audio. (unless you can afford to recompress your video files)
That is, if you video files use a high bit rate (say over 6 Mbps average), then it's usually necessity to use Dolby compression to make sure that all your footage fits on a single disc. (this is a simplification, of course, but I think you get the idea)
Or was there more to this question that I'm missing?
I live and work with video in Europe, where I have recently been told that optimal audio is mp3? 4? rather than Dolby 5.1? Is this correct, and how much more space does dolby 5.1 take than dolby2? How significant an issue is this when making dvd's for musicians?
Someone was mistaken when they told you that DVDs accept - let alone are optimized for - mp3 or mp4 files. That's flat out wrong.
As for the difference between Dolby 5.1 vs 2.0, that depends on your encoding rates. Typically, most folks encoder Dolby 2.0 at 192 kbps, with some choosing to up the bit rate to 224 kbps. Beyond 224 kbps, you're not actually improving audio quality for a 2.0 mix, you're just bloating your file size. When it comes to 5.1 audio, it's typical to encode your audio at 384 or 448 kbps.
When it comes to compressed audio vs uncompressed audio, it does matter when you're making DVDs for musicians. But that means that you'll probably need to lower the bit rate on your video files.
Lastly, can someone recommend the best quality audio-video compression solution for a dvd containing approx 40 minutes of audio and video footage for use in europe??
If you want to keep you audio as AIFF files, set your encode to 2 Pass VBR Best, with an Average bit rate of 5.0 Mbps and a Max bit rate of 7.0 Mbps. If you need things to happen a bit faster, use One Pass (not One Pass VBR) and use 5.5 Mbps as your bit rate.
If you want to have a firm grasp over how all these numbers work, there is a section at the back of DVDSP manual, that explains how to calculate bit rates (what we call bit budgeting in the business). Give that a quick once-over if you can.
