Turbo.264 and Quicktime Broadcaster

Anyone know if these two are compatable?
Trying to speed up my encoding speed on live streams on my xserve g5.

Much thanks for the feedback.. I was hoping it might've been a possibility (since I like the concept of being able to do h264 640x480 encoding without hiccups without having to use a macpro)
I did leave them some email with a few questions, so hopefully I'll hear some good news I put a post on a different board about compressor support too, since I figured that would be pretty helpful as well if it was compatable there.

H.264 and Quicktime

hello everyone,
i'm currently under the process of converting all my videos from home movies to dvds, movies, through with h.264. I have recently found out through the Mpeg industry forum head Gary Sullivan that the "main" profile was a profile that was implemented on a semi-temporary basis until they came up with the "high" profile. now as many of you know, the high profile doesn't exist in QTPro or FCP. I also found out that at the same bitrates "high" has better algorithms than "main" and "main" better than "baseline" so perceived visual quality is better at the same bitrate. Obviously it would be advantageous if I could encode all my videos using the "high" profile. So on to my questions:
1. What is the best/most widespread application to convert your videos to the "high" profile for h.264?
2. If I have videos encoded in the high profile, will QT natively support them and play them back or not?
3. Is it worth going with "high" over "main"?
4. What is the difference when encoding in h.264 to using a .mp4 container or a .mov container?
Thanks everyone.
Nick

The "best" application for mass conversion of video would be either Apple's Compressor 3 or Telestream's Episode Pro since both have high quality codecs and feature batch encoding. There may be a problem with cost however since Compressor is only available as part of Final Cut Studio ($1300) and Episode Pro is $895. I use both (I'm in post-production) and they're pretty equal. The econo way to go is QT Pro.
None of what you had about Gary Sullivan, et al. made much sense to me although I've been working with H.264 since early 2005. What I can tell you is this:
Unless your library of movies, etc. are of spectacular quality, you needn't be concerned with "high" quality issues. H.264 has been touted as "half the filesize of MPEG or twice the quality" and I see that as true. In my experience that "medium quality" H.264 is quite presentable. It will usually compare favorably with 25Mbps DV-NTSC at a bitrate of less than 2Mbps.
H.264 is technically MPEG-4, layer 10. It is also called AVC (Advanced Video Codec) and AVC/HD. Which wrapper QT chooses to isn't important. In the mid-term future, you will see H.264 infiltrate pretty much all forms of video from 3G to 4K. The one place you won't find it is in conventional video DVD. You can write H.264 to DVD-ROM as data, but if you intend to produce conventional Video DVDs of your library, you'll be encoding as MPEG-2 or MPEG-1 since those are the only allowable formats by DVD standards.
Good luck.

Turbo.264 and compressor

Anyone know if these two are compatable?

If you're encoding the audio to AC3, the default preset in Compressor includes a dialog normalization setting as well as a film compression setting that does lower the level. It's best to create a custom AC3 preset with Dialog Normalization set to -31dbfs and Compression type to NONE.
If you're encoding the audio as PCM, there should be no discernible level drop that I'm aware of.

Quicktime Broadcaster - getting it online

I'm trying to work out how to stream my webcam live onto my website.
I have installed QTSS and Quicktime Broadcaster, and managed to set it up so it can be viewed around my home, but I have no idea how to get it out and onto the internet or embed it into my site (after a LOT of searching Google).
Can anyone explain?

We were using two Canopus ADVC110 Video converters as I have medical use which is allowed for these devices. This is also the reason I cannot use other video converters at the moment. We were streaming H.264 only as plain MPEG4 would not have met our bandwidth restrictions without serious danger of massive dropouts. (A different story, not QuickTime's fault.)
With a Testbild (bars and tone) I actually didn't have a problem, even for prolonged periods. Maybe because the Testbild was came from the SONY betacam we used. Quality was nothing short of stunning. With the ultrasonic echo-scanner image locked I experienced problems with the upstream breaking after a few minutes. Maybe also because this stream was video only.
I'll try and experiment with UDP upstreaming if that helps with the disconnects.

Elgato Turbo.264?

So I am looking into expanding my mac mini for use of audio and video editing. I have used my mini for about a year now for doing professional audio editing in Logic Express and have found it just dandy, still do. But my 80GB internal harddrive was getting even more cramped, especially after loading 10.5 Leopard a few days ago. Plus my 120GB and 250GB external HD's are packed with audio and video content I can not afford to erase so I went out and purchased another Lacie, 500GB USB2.0 and it works amazingly.
BUT... I feel my graphics are lagging. This is of course because the mini has integrated graphics, but more then this, while rendering in Final Cut and Motion. It has become a MAJOR pain, especially when my friend with a MB Pro sits next to me rendering the clip super fast. So I saw the elgato turbo.264 which states it will help with this, i have also read reviews into it.
My only question is, will this overtake day-to-day graphics processing? Thanks for any help!

turbo.264 will not accelerate, thus will not help you, your rendering needs. That job belongs to your CPU and your GPU, which are limited in a Mac Mini.
I own elgato turbo.264 and really does work and speeds up things in my dual 2.0 GHz G5 tower.
Because of my work, I encode a lot of videos to Apple Devices codecs in H.264. That is what the turbo is made for: encoding. it is not a graphic accelerator. it is an encoding accelerator. Regarding it being a USB, that has no effect. It works and does that fast. Time is money and now I am able to encode many times faster.
On the negative side, I have not been able to use it as an export component with Compressor just because I prefer it for professional jobs that require more control and metadata within the output file. If that does not apply to you, their application works perfectly and does batch exports. It also has custom settings.
Another minor negative is that Apple TV export are limited to 800x600 or 960x540 (anamorphic) thus not supporting the AppleTV supported 720p24... looks good but is less than what the AppleTV is capable of as long as your footage is 24 frames per second.
Hope this helps and that it can answer your question.
To me, I give elgato 4.9 out of 5.0, which I'll change to 5 out of 5 as soon as I can fix the Compressor thing

Quicktime Broadcaster not recognizing camera

I have a Canon Vixia HF10 and Quicktime Broadcaster will not recognize the camera. IMovie and Final Cut Pro recognize this camera on the same computer. Is there a fix for this?

I assume, the experts in the QT forum are better on that ..

Quicktime broadcaster how tosave life feed to .mov

Hello,
after quite a bit of fiddling, I finally figure out how to stream live A/V to the internet using Quicktime broadcaster, Darwin Streaming server and Mavericks Server.
Now the last hurdle is trying to save the live feed into a file such as .mov, but I am not sure how that can be done.
In the Quicktime broadcaster, there is a check box next to the Broadcast button that says Record to disk. but it seems only record to a .sdp file. How can I record to a .mov?
Thanks in advance.

Well good news... I've solved my own problem. So I thought I'd share my fix. As it turns out, I needed my Yamaha USB mixer... the feed just would not work internally. In the computer Preferences, my Sound Output setting is now set to "Built in audio" and piped out to my Yamaha Mixer via mini-jack to Stereo RCA cable. Next the Sound Input setting is set to the USB Codec which is the send from my Yamaha USB mixer. Then Simply iTunes outputs to the mixer via internal audio and QuickTime Broadcaster collects the audio feed via the USB connection. No more horrible feedback loops, and a steady feed that hasn't dropped out all night.
One other point, there is a buffer delay of two minutes which for some reason I forgot to take into account. So sound adjustments are slow and require quite a long wait to see if the setting adjustments requires more tweaking when listening to the feed over the internet. So a good idea is to use a good peak limiter to cap your feed.
I hope this helps someone in the future.

Quicktime Broadcaster and baseline H.264/AVC

Is there any way to force QT Broadcaster to encode to baseline profile when encoding H.264?
PowerMac G4 Mac OS X (10.4.7)

Has anyone been able to create a iPod Video compliant video recording from QuickTime Broadcaster?
Don't believe Broadcaster accesses the "baseline" H.264 profile required for iPod compatibility. Use the "Movie to MPEG-4" export/share option to create "custom" iPod compatible files in QT or use a third party utility with user settings. You can also try any of the dedication QT conversion options but files will likely be much larger.

Quicktime Broadcaster H.264 Configuration

Hey,
Does anyone have any knowledge of how to configure H.264 settings in Quicktime Broadcaster?
The specs on www.apple.com/quicktime/broadcaster/specs.html say it supports both H.264 Baseline profile and H.264 Main profile, but the software only gives "H.264" as an option (the "Options" button greys out when you select H.264), and it is putting out a H.264 "Main profile" stream.
Does anyone know how to switch this over to a H.264 "Baseline profile" stream?
I'm running QT Broadcaster 1.5.3 under MacOS 10.5.7 with Quicktime Pro 7.6.2.
Thanks!

After many conversations with Apple representatives, I don't believe Baseline encoding is possible in QuickTime Broadcaster at this point, sorry. I would be interested in this feature too! Too bad they don't seem terribly concerned with updating the software.
In the forums for Wowza Streaming Server (link: http://www.wowzamedia.com/forums/showpost.php?p=20815&postcount=29), someone has claimed success using VLC to live encode to baseline profile, using the following settings:
venc=x264{keyint=25,nocabac,level=3.0,qpmax=36,qpmin=10,me=hex,merange=24,subme= 9,qcomp=0.6},vcodec=x264,vb={VB},width={SIZEW},height={SIZEH},acodec=mp4a,ab={AB},channels=2
Haven't had a chance to try it out myself, but VLC is certainly flexible enough to accomplish this. (Whether it do so reliably is another matter...)

Elgato turbo.264 export fails in Compressor as a QuickTime Component

I would like to know if any user of Compressor 3 and elgato turbo.264 hardware accelerator has had succes in using the device as a QuickTime export component within Compressor.
I setup a few export settings but the Batch Monitor reports "3x encoder type unavailable".

You should report this to Elgato on their support site if you have not already. Add a trouble ticket here: http://support.elgato.com/

Separate audio and video inputs for Quicktime Broadcast?

I want to produce some real time streaming via Quicktime Broadcast. My audio will be coming from a Mackie mixer with firewire interface, the video will be coming from my video switcher which has a firewire output. Will I be able to combine the audio and video firewire feeds in the computer (or software), or must I combine the audio and video into one firewire feed before it hits the computer?
Thanks!
Rob Cook

I just did my first feed Monday night. I used a video mixer and Mackie board myself. I feed the audio and video(component) into my DSR-20 VCR, which I also use for a tape backup recording. This then feeds the QT Broadcaster. I don't think you can feed anything but a firewire machine or iPhoto camera into Broadcaster. Might work with an USB camera/vcr???
I feed H.264 video, at 320x240 with mono 16 bit audio. Hint... don't do disolves, as they increase the frame rate. simple cuts-only seems to be the best. We also fed keynote slideshow into switcher... carefull there, as it produces saturated colors that will effect the signal... the switcher will think the super saturated video is sync and glitch the video. red is the worst, of course. Next week I am going to use a little proc amp to drop the chroma a bit.

Quicktime Broadcaster 1.5 and Darwin Streaming Server 5.5

Since i upgraded to Quicktime Broadcaster 1.5 (as i want to use H264) i can't use any more the Automatic Unicast (Announce). It says 'Broadcast error disconnected (-3285). I updated to Darwin Streaming Server 5.5 (on SuSE 9.1 Linux on a hired server with 2 IP's, one binded to DSS, the other to Apache to enable Streamin over port 80) but it doesn't help. I tried with Wirecast instead and everything workes fine (at least it created the .sdp file correctly) so i don't think the problem is in the Streaming Server Set up. Anyone has experienced something similar with the new Broadcaster?

We use 10.3.9 server here on three different machines. Two of the three disconnect from Broadcaster after about half an hour, with the -3285. The third system will not even allow a connection to start, ever. I am thinking that the automatic unicast file has a permissions issue. All of the three servers have Open Directory enabled. I want to turn it off, but I am not sure what will happen to the rest of the server's abilities if I do. Does anyone run in an Open Directory disabled configuration?

DV clips look bad, good when converted to H.264 in QuickTime and reimported

Still a problem after 7.0.1:
DV camera -> iMovie 08 -> looks bad when playing and exporting/sharing
DV camera -> iMovie 08 -> "reveal in finder" -> clip opened in QuickTime -> looks good -> export as H.264 -> re-import to iMovie 08 -> looks good when playing and exporting/sharing.
In plain words: Importing DV clips from my DV camera into iMovie gives bad results when playing and exporting/sharing. Have tried everything, but the clips look blurry and not sharp at all. The actual DV clip in the events folder looks sharp and clear.
If I take the very same DV clip from the events folder ("reveal in finder"), open it in QuickTime, export it as H.264 and then re-import to iMovie 08, it looks brilliant, retaining the quality the DV clip in the events folder has.
Why can't the DV clips look good in the first place? What is it that iMovie 08 does to these poor clips? Some have suggested re-encoding, re-rendering and so on, but if I do just that in QuickTime and re-import it to iMovie 08, it still looks razor sharp and crystal clear. No reason that iMovie 08 shouldn't handle the DV file in the same manner.
Some have suggested that this is because iMovie 08 internally re-encodes to AIM or H.264, enabling edits with different kinds of formats, but if I do this myself in QuickTime before importing to iMovie 08, the problem isn't there!
If this is difficult to achieve, why not add the option of importing from a DV camera as H.264 and not DV? That would make my day!
(I have posted this to Apple using the feedback menu item in iMovie 08.)
(Background here in these threads:)
http://discussions.apple.com/thread.jspa?threadID=1088568
Sample clips in Apple TV format here:
http://discussions.apple.com/thread.jspa?messageID=5173005

iMovie '08 stores rendered projects in H.264 form. This happens when you render to the Media Browser. The rendered file(s) (you can have several different sizes) are in the iMovie '08 project package. The original flies in your Events folders stay in whatever format they were in.
Yes, the movies exported to the Media Browser use the H.264 format, the same as iMovie HD 5/6 did when we exported using the presets Email, Web, Web Streaming and CD-ROM. They were all H.264 too. Apple is obviously putting the (powerful) H.264 to good use to prepare movies for Web pages and other purposes.
As you know, the Full Quality export in 5/6 was to the project's native format, which varied according to the type of project. For DV projects, that was DV video. Everything was converted to DV when imported into the project, and to preserve the original quality we could export to a Full Quality DV movie.
There is nothing like that in iMovie 7, at least that I've seen. As you said, nothing is converted to a "native format" when imported to the project. (Still images are added to the project's single Apple Photo - JPEG "Still Images" movie, which is a nice twist.)
So I think of iMovie 7 as having no "native" format, but a nicely-designed path for using H.264 as the delivery format. The Media Browser — a virtual library of movies with no shared place — is a nice invention.
When I export slideshow movies in DV format out of FotoMagico I always select 'Best' and it DOES make a difference in iDVD.
I think of iMovie 7's problem with DV as more profoundly flawed. Exporting ANY DV video that's in the project to DV or ANY OTHER format is messed up. It's the handling of the DV inside iMovie that's messed up, not just the export to DV.
My guess is — and it's only a guess — that FotoMagico's Best setting adjusts the content of the image delivered for iDVD. Put another way, it prepares an image that works best with iDVD's own encoding algorithms.
One long-standing diappointment I've had with iLife is that Apple has never coordinated the image it prepares for iDVD with what(ever) iDVD does best. It's as if the programmers never talk to each other. iMovie engineers have never asked the iDVD engineers how best to deliver the image to deliver the best quality on the DVD.
Given Apple's emphasis on H.264, one would think that iDVD would be written to embrace any H.264 video and deliver great quality on the DVD. It doesn't. And with iLife '08 it doesn't even embrace iMovie's own DV exports!
I suppose Blu-Ray will change all that, but for now we're stuck with a version of iLife that can't deliver a quality DVD of our home movies.

HELP!!! EyeTv and Turbo.264

This is driving me mad!
When I use the 1'click export to Apple TV button on EyeTV2 with Turbo.264 plugged in, the red progress bar will go up and then down and then up and then down... and keep doing this for ages.
Then it will do one of two things:
1. Delete the output file leaving nothing
2. Leave me with a file which has the video broken up in the wrong order, but with constant (correct) Audio - (maybe the video is mirroring the jumping red progress bar??)
Without turbo.264 plugged in, it's fine. The iPod export works fine, as does the AUTOMATIC Apple TV export which you select for each 'Scheduled' programme.
I am using the latest software for ALL aspects.
Any thoughts much appreciated.
Thanks!

I have also bee using EyeTv 2.4 and h.264 1.1 since day dot and all is working perfectly. The only issue I have is that once exported and imported into iTunes the software doesn't clean up and remove the converted file from my Movies directory (I found 50gb of HDD last weekend)....
Cheers.

Quicktime Broadcaster and Leopard - no audio

I use Quicktime Broadcaster a few times a week for a contract I have. Everything worked fine as of Friday morning. After the upgrade to Leopard, I noticed that the app would no longer encode the audio of video. This only occurs on a MacBook Pro. An old PowerBook works sort of OK, but not perfect, have some other issue as well. I booted into a back-up of my previous set-up, and all works as it should.
Any ideas on how to fix this? I have looked everywhere, and do not see any errors in the logs to help troubleshoot. All settings look OK. I can record audio with Audacity, but not Quicktime Broadcaster.

This does not seem to work for the live stream, only the locally archived stream has the audio. Am I missing something? A setting I am unaware of?
