[videoblogging] Re: Compression best practices
I use VisualHub for the mac to make all of my versions. Flip4Mac handles the WMV encoding (enables it for VisualHub, IIRC). The only time I'll use quicktime player, FCP or Compressor is when I need to make sure I have control over keyframes, etc. As far as quicktime, I found out from Justin Kownacki (http://somethingtobedesired.com) that there's a color depth difference between h.264 and regular mpeg-4. I agree with him that regular produces richer colors, but I still use h.264 for the lower data rates. ~Bill http://billcammack.com --- In videoblogging@yahoogroups.com, Adam Quirk qu...@... wrote: Hey all, I've used several compression UIs over the years, but I'm curious to hear what your favorites are, and what your process is.

Here are some differences and things to note about these settings: 1. The Vimeo settings, I'm sure, work well as you say but - Sorenson 3 is an older, less effecient codec. This is why you noted similar quality at 2X the bit rate. 2. QDesign Music 2 audio codec often sounds very tin can and swirly to me. Also it's much less effecient than AAC. 3. The mpeg4 video codec and AAC audio codec settings we show at Freevlog will give you iPod compatible video. Sorenson 3 and QDesign Music 2 are not compatible with the iPod. 4. Apple's version of the mpeg4 codec is certainly not the greatest. You can increase the quality (like with every codec) by increasing the bit rate from what we recommed in the tutorial. 5. Another option is to use the h.264 codec but there are some downsides: Apple took away the ability of using h.264 to make ipod compatible videos except when using export to iPod, which last time I checked, had the effect of squishing you video if it originates as DV; also h.264 requires QT7; and h.264 plays poorly on older computers. 6. Personally, my perferred option is to use the 3ivx version of the mpeg4 codec ($20 from 3ivx.com - but the free trial lasts forever). We have a tutorial on Freevlog for using the single pass version: URL: http://freevlog.org/index.php/2005/10/23/compress-for-the-web-with-3ivx/ and one of these days I'll get around to making a tutorial for using the dual-pass version which gives results close to those of h.264. The reason why we don't already have that tutorial is that there is a bug with 3ivx dual pass and QT 7. There is an easy workaround (I use it all the time) that can be found here: URL: http://forums.3ivx.com/index.php?s=e927e67253f3bec43952d568e6e99b7cshowtopic=83898st=0p=416725#entry416725 Hope that helps, Verdi On 4/24/06, M.

[videoblogging] Re: Compression... quicktime sucks
Hi Nathan, if you want to compress your videos out from FinalCutPro, you can either use Quicktime Codecs directly built-in, third-party QuicktimeComponents or export them from FCP with DV or Apple Pixlet and then use another program to encode. IMHO Quicktime for most things is the worst solution. If you take Apple ASP-mpeg4 it´s just incredibly bad quality and no options, Apple H.264/AVC mpeg4 is better but still worse than others. You can take the Divx or 3ivx or the x264 Quicktime Component, but none of them worked well for me (BTW i´m talking about MacOS X). Divx gives you .divx files not mp4. 3ivx not sure it works with Quicktime 7, x264 component isn´t stable and bad results. so i think best is to export and encode outside of FCP using OpenSource codecs or any other better one. for mac i recommend: D-Volution, ffmpegX, MPEG Streamclip. for fairly good iPod - Movies iSquint is good too. --- In videoblogging@yahoogroups.com, Nathan Miller [EMAIL PROTECTED] wrote: I work in FCP... how do I get a 10 to 12 min bicycle sidewalk under 50MB!!

[videoblogging] Re: Compression techniques - file size ratios
3ivx has its own encoder, and indeed its own decoder. So whilst it can be a quicktime plugin, it isnt making use of Apples own mpeg4 encoding/decoding routines. Because it creates compliant mpeg4, other decoders can be used to play it back, including appls Quicktime one. With QT6 if you install 3ivx, it uses its own decoder for playing mpeg4, and this was apparently a bit better than Apples, maybe a bit faster. But there are reports that the 3ivx decoder doesnt work right on QT7, or is disabled, Ive seen conflicting info. Anyway the short answer was no, it doesnt just access additional settings that effect encoding, it is an encoder in its own right. On Windows you dont have to use it with quicktime at all.

Yes, thats it, thats exactly why most 3ivx files will play on the ipod, because 3ivx is an encoder that creates standard mpeg4 video. It is possible to create 3ivx files that wont play on the ipod, because it is possible to create mpeg4 files that wont play on the ipod (or eg if you use a audio format other than AAC), but most peoples will work just fine. This stuff ties in to why I cheer for .mp4 not .mov though. The ipod only supports .mov because its also apple, wheras most mpeg4 devices will want .mp4 files and the same is true of some software mpeg4 players, especially on the PC. 3ivx-encoded .movs are widely compatible, but 3ivx-encoded .mp4 files are even more device/future-proof. .mov requires one specific company to keep it alive, not so of .mp4.

[videoblogging] Re: Compression techniques - file size ratios
You will notice almost no difference in filesize, maybe a few k, but
the audio and video are taking up the same space with either.
Fast start (progressive download) does work with mpeg4. For a while
some thought it didnt, but mostly it does. I appealed recently for
anybody who could remember how to make a mpeg4 that doesnt fast-start,
because all the ones Ive got do fast-start. This includes .m4v's made
by qt7.0.3 ipod export, though I prefer to rename them to .mp4 to
avoid having yet anothr mimetype issue to deal with.
Where fast-start certainly doesnt work is on Internet Explorer (Ive
only tried PC vversion). If you dont embed code to make the video to
launch with a specific player within the page (ie if you just link to
the video file directly), then you wont get a progressive download, IE
aits till the whole file has downloaded before quicktime appears in
the browser to play it. But this happens with both .mov's and .mp4's,
so Im drifting offtopic, but its probably the number one reason some
sites dont end up giving all their users a fast-start experience right
now.

[videoblogging] Re: Compression
Regarding your compressed file ending up bigger than your original: Your camera creates footage that is already compressed, and the settings you are using to recompress are for higher quality/less compression than the original, hence the larger file. Bitrate is the key. This tells the compressor how much data space it is allowed to use per second for the video. I would start off by looking at exactly what compression is used in the files your camera creates. Load a mov that came from your camera into quicktime and go to the window menu and select 'show movie info'. Format, FPS and data rate are the important ones, if you let this group know what they are, can give you more specific advice. Also if you see someone elses video that you like the looks/filesize per minute of, then you can do 'show movie info' on that and find out what bitrate etc they use. Unfortunately things can get a bit more complex than this because theres all sorts of other options in the compressor software, factors that can affect how good the video looks and how much it honours other settings like the bitrate youve chosen. For example your camera might create videos that are mpeg 4, 320x240, 12FPS and a bitrate of 256k. If that were so, there would be no point in recompressing at a higher resolution, framerate or bitrate, because you wont gain anything, just end up with larger files. The same applies to audio, if your source footage is mono 24khz 64kb then there would be no point recompressing to 24khz stereo 128kb or whatever. Regarding files being much larger than other videoblogs: If followed fully the guides for compression that are on freevlog should suit most people, it shouldnt create files that are way larger than most videoblogs out there. So if you end up with really large files, either you made a mistake with the instructions, or theres a bug in some part of the process (for example if you used 3ivx to compress with qt7, it seems theres a bug so it ignores your bitrate settings and you could end up with much larger files than you should). The only limitation with the guides is that they are (by design) quite general, they have mostly been used by people using DV cameras where the original videos are very huge (13 gigabytes per hour) because DV isnt compressed as much as cameras that use mov, mpeg4 etc. So pretty much whatever setting they use for recompression, it will be a lot smaller than the original. And if they recompress with high bitrate then the footage will look better than with low bitrate. But if your camera only records at a low bitrate in the first place ther is no point recompressing to a higher one, as I said earlier.

Oh, this is great information. I will study it. Answers a lot of my questions. Thanks so much! -Bev - Original Message - From: Steve Watkins To: videoblogging@yahoogroups.com Sent: Wednesday, August 17, 2005 11:13 AM Subject: [videoblogging] Re: Compression Regarding your compressed file ending up bigger than your original:Your camera creates footage that is already compressed, and thesettings you are using to recompress are for higher quality/lesscompression than the original, hence the larger file.Bitrate is the key. This tells the compressor how much data space itis allowed to use per second for the video. I would start off by looking at exactly what compression is used inthe files your camera creates. Load a mov that came from your camerainto quicktime and go to the window menu and select 'show movie info'.Format, FPS and data rate are the important ones, if you let thisgroup know what they are, can give you more specific advice.Also if you see someone elses video that you like the looks/filesizeper minute of, then you can do 'show movie info' on that and find outwhat bitrate etc they use. Unfortunately things can get a bit morecomplex than this because theres all sorts of other options in thecompressor software, factors that can affect how good the video looksand how much it honours other settings like the bitrate youve chosen.For example your camera might create videos that are mpeg 4, 320x240,12FPS and a bitrate of 256k. If that were so, there would be no pointin recompressing at a higher resolution, framerate or bitrate, becauseyou wont gain anything, just end up with larger files.The same applies to audio, if your source footage is mono 24khz 64kbthen there would be no point recompressing to 24khz stereo 128kb orwhatever.Regarding files being much larger than other videoblogs:If followed fully the guides for compression that are on freevlogshould suit most people, it shouldnt create files that are way largerthan most videoblogs out there. So if you end up with really largefiles, either you made a mistake with the instructions, or theres abug in some part of the process (for example if you used 3ivx tocompress with qt7, it seems theres a bug so it ignores your bitratesettings and you could end up with much larger files than you should).The only limitation with the guides is that they are (by design) quitegeneral, they have mostly been used by people using DV cameras wherethe original videos are very huge (13 gigabytes per hour) because DVisnt compressed as much as cameras that use mov, mpeg4 etc. So prettymuch whatever setting they use for recompression, it will be a lotsmaller than the original. And if they recompress with high bitratethen the footage will look better than with low bitrate. But if yourcamera only records at a low bitrate in the first place ther is nopoint recompressing to a higher one, as I said earlier. This isnt toomuch of a problem as the guides use a fairly low bitrate anyway, butId still like to know what settings your camera uses to give you themost optimised settings for your setup.Oh dear I hope my waffle hasnt made things more confusing.

There is to much information to encode, thus it looks blurry and fuzzy. if it is animation that has a lot of flat fields of colour then the animation codec in quicktime will probably work best. :-) if it is 3D and more film like, then yes, compression will be hard because you may have sharp edges where as codecs all introduce noise to make stuff look better. work around is to add more noise then compress. add noise in compression, drop frame rate, screen rez, and so on. -- cheers Adrian Miles hypertext.RMIT URL:http://hypertext.rmit.edu.au/vlog YAHOO!
