H264 encoding

Does anyone know when this will be available on AIR for Android?

Before we go any farther, please turn of you CAPS. It makes the post very difficult to read and is considered shouting in the internet world.
Thank you.
Now,
Usually crashes in encoding can be traced back to:
1. corrupted media files
2. improper naming conventions
3. disk storage issues.
We need more information.
What format is the original material?
What Version of Final Cut Pro?
What Verison of OSX?
How many disks in the computer and how much space on the media drive? (you are keeping your media on a different drive than your OS, aren't you?)
report back,

Quicktime 7.6.4 won't play h264 encoded videos on my 10.4.11 MacMini

Hello:
This is my first post. I read through the forums and this seems to be the correct place to pose my question. If it's not, my apologizes.
I'm trying to find out why Quicktime 7.6.4 won't play h264-encoded video on my MacMini (G4 PPC). I'm running 10.4.11. I recently installed Perian 1.2.1 and it got some .avi files to play correctly, whereas before there was no sound. But the h264 files still get me a black screen, albeit with sound now. Some h264 files can be played in VLC Media Player (but that's a horrible player compared to Quicktime in my opinion, as it constantly drops frames and eats 100% of my processor time), but VLC even has the black screen problem on some h264 files as well.
I've also tried MPlayer OSX but that's really an alpha-type development and has a lot of bugs. Many movies it can't even open.
Sorry for the rambling, but again my question: Is there any way to play h264-encoded video in Quicktime 7.6.4 on my Mac?
Thanks in advance for your expertise and advice.

Mr Ram,
There is a group of Quicktime specialists in Apple.com ⇒ Support ⇒ Discussions ⇒ Quicktime .
The more data you give us, the easier it is to help us help you to diagnose your problem. Your disk space would be very useful. Contrary to some, I advocate iDefrag to assist VLC and MPlayer, which you were a little hard on.
GNU/Linux's free offerings
MPlayer was developed a decade ago, and I prefer it for viewing DVDs (for 'DVD Player') seems too dark. VLC (legally) copies many CRM-protected DVDs of yours, so you can play only the burned copy. When I'm having a problem playing a DVD, the VLC log tells me all: only perfect DVDs play well on VLC.
There are two ways of viewing everything.
Streaming MPEG-4
+H.264/MPEG-4 AVC+ is a fancy codec based upon MPEG-4: it requires a powerful processor to de-compress it. I watched an MPEG-4 movie from a G3 iBook in 2005. It played flawlessly.
Your Problem
Quicktime 7.X applications can not play +H.264/MPEG-4 AVC+ streams. It was a bug Apple never fixed. Frames are dropped because H.264 is so slow that it requires special hardware. You, I'm sad to say, don't have it.
To quote the Wikipedia on Quicktime: 'QuickTime 7 lacks support for H.264's Sample Aspect Ratio .[67] QuickTime X does not have this limitation; many Apple products (such as iTunes and Apple TV) still use the older QuickTime 7 engine.'
My Quicktime Pro on a PPC PowerBook is 7.6.4. You can either use a Linux transplant or upgrade to Quicktime X. Those more familiar with Macs may have better ideas for you.
My best,
Bruce

IBooks Author crashes every 30 seconds: h264 encoder?

I am using iBooks Author 2.1.1 on Mavericks.
The program is crashing like every 30 seconds for no apparent reason (specific actions, that is). I cannot see the <edited by host> problem reporter anymore . This is what it offers all the time stating some problem with the h264 encoder framework (please see attached image below). A reinstallation has not helped so far. What can I do here?
Many thanks in advance,
Jan

Did you already try removing iBA's preference plist as part of your troubleshooting process?
I don't think that plugin is the culprit ...perhaps more like an incidental victim in this example.
However, as this is a predicable issue, you may want to get Apple Support on the phone and let them take a look.

H264 encoding settings - problems with FLV/F4V conversions and playback... HELP!!!

I do a lot of LIVE ENCODING and have been struggling with FMLE. I own the Adobe Creative Suite of applications and am pretty familiar with working with compatible/required formats, etc.
We have been primarily using VP6/mp3 for encoding. Most of our work is SD. We also always seem to have trouble when trying to encode the FLV file to another format, audio always seem to be out of sync, but sometimes it works...
Do you know why that would be regarding the FLV audio falling off sync when encoding to another format, such as MOV? Also, when we try to play back the FLV, the audio sounds garbled up and only plays well in Adobe Media Player.
I keep hearing H264 encoding will provide better video, but I just can't get that to work. Also, why is it that my entire CS4 suite of applications can't read or playback the F4V file- that's unacceptable from Adobe, just a big huge pain the butt... I've had to buy several cheapie applications to try and read F4V files and try to convert it, except that converting F4Vs seems to be a hit-or-miss.
What should I be using to playback and convert F4Vs? I also heard changing the extension to MP4 works, but I haven't seen that work, not even once. The cheap video conversion apps I have that read F4Vs are: FFMPEGX and Wondershare (Youtube). Sometimes they open F4V, but not most of the time...
I am using a super fast new Macbook Pro i7, 8GB ram (not the thunderbolt/usb3), CPU always runs smoothly and effectively.
Also, I always use the Canopus ADVC-110 as my transcoder. I do both video via Firewire IN or Composite IN, then Firewire OUT into the Mac encoder. FMLE sees it ok, but I wonder if this device might be my problem.
VP6 settings are as follows:
VP6 video / MP3 audio
300 to 500k video
30 fps
640x480 in/out
44100hz audio
56k audio
We want to start using H264 encoding settings, but in my experience trying it out, the output file is ALWAYS PROBLEMATIC. Also, when testing a live stream, the audio seems to fall off sync with the video.
I am looking for your recommendations on the H264 settings I should try. Most of my events are simple meetings with 1 to 5 speakers, mostly talking heads. We rarely encode high motion video, but I would also like to be able to adjust H264 settings for both talking heads and medium to high motion without (any) frame drops.
I have tried streaming to multiple/different Flash Media Servers, archived only to file, and H264 results seem always bad.
Any recommendations from professionals in the live streaming arena are much appreciated. I thank you for your time in advance.
Thank you!
Hugo

Hello Hugo
Sorry to know that you are facing these kind of issues, let me try to reply and understand issues one by one.
>>We have been primarily using VP6/mp3 for encoding. Most of our work is SD. We also always seem to have trouble when trying to encode the FLV file to another format, audio always seem to be out of sync, but sometimes it works...
-- Which application you are using to convert FLV to other format?
-- Is these any Audio - Video sync issue when you play FLV file in Adobe Media Player? if NO, it means FLV file created properly.
>> Do you know why that would be regarding the FLV audio falling off sync when encoding to another format, such as MOV? Also, when we try to play back the FLV, the audio sounds garbled up and only plays well in Adobe Media Player.
-- Which application you are using to convert FLV to MOV? if FLV playabck fine and without a/v sync issue, it should convert MOV with a/v sync.
-- It depend on audio codec selection by Media player or correct audio codec not installed for media player. Install appropriate audio codec to play in other media player if you dont want to play in Adobe Media Player.
>> I keep hearing H264 encoding will provide better video, but I just can't get that to work. Also, why is it that my entire CS4 suite of applications can't read or playback the F4V file- that's unacceptable from Adobe, just a big huge pain the butt...

-- Adobe Flash Media Server version 3.5 and later and Adobe Flash Media Live Encoder 3 can record content in MPEG-4 (F4V) format using an industry-standard recording technology known as "fragments" or "moof atoms." Some MPEG-4 compatible tools and players do not support moof atoms.
The F4V Post Processor tool aggregates the information from all the moof atoms into a single moov atom and outputs a new file." You can download the tool from above location: http://www.adobe.com/products/flashmediaserver/tool_downloads/
Thanks

SAVE AS using h264 encoder

Do any of you see apple adding an h264 encoder to Pro so we can all save bluray movie backups?
if not what's a good program I can use for backing up these disc's?

If I can open them as .avi and then save them as iPod compatable GREAT... Did I understand your answer correctly?
Yes and no. The "Save As..." option saves data in its current compression format to an MOV file container. (E.g., a DivX video with MP3 audio in an AVI file container would end up as DivX video with MP3 audio in MOV file container if you try to use the "Save As..." File menu option. On the other hand, QT Pro, GarageBand, iMovie, iTunes, MPEG Streamclip, and other applications can acces iPhone, iPod, and/or TV specific device export presets which will convert "QT Component compatible" files to H.264/AAC files using the "Export" file menu option. (For instance, the iPod preset will normally play on all three devices with slightly better quality than the iPhone preset while the TV preset, if properly encoded, will not play on either of the other two devices.) The basic difference between the two options is that the "Export" option performs a mandatory transcoding of data even if it is to the same format while the "Save As..." option does not.

Problems with H264 encoding -- corrupted files...

In Media Encoder CS5 I tried to export my Premiere Pro CS5 sequence with H264 encoding(30 fps, progressive, CBR 6 mbps, 640 x 480). Audio(AAC, 48 kHz, 256 kbps). It have made a corrupt video file(with 2 GB size, and it should be ~3,5 GB). I tried to re-export with these settings, and now the size was 1045 MB. Again corrupted file, it cannot be played... The Media Encoder says that there is no errors, the rendering was successful. After several other tries with different settings, I cannot render my movie.
What can I do?
Thanks for help!

Hello all,
This is an old thread, but it's an old problem that I'm concerned may still be continuing.
We're moving from 3.2 to 4.1. While copying our applications from 3.2 to a test 4.1 installation, we did a static file export for "All static files" from 3.2 and did an import to 4.1. We're seeing the same behavior that I and others have reported in the past - any static files that are javascript are corrupted when "all static files" was chosen. Exporting/importing each javascript static file individually appears to work fine.
If the bug was in 3.2 in that it was generating a corrupted export file when "all static files" is chosen, then I'm not concerned - we're moving from 3.2 anyway. But, if the issue is in the import then it must still exist in 4.1 and that would be a concern.
Does anyone know if this was a recognized bug in 3.2 and has since been corrected?
Thanks!
John

H264 ENCODING PROBLEMS PLEASE SOMEONE REPLY

I HAVE H264 ENCODING PROBLEMS TO ALL APLICATIONS
FC PRO IMOVIE HD EVEN QT7.
IT GOES VERY SLOW!!!!! FOR ENCODING AND CRASHES ALL THE TIME.
FOR THE FIRST MIN GOES VERY FAST AND THEN DRAMATIC SLOW ANDIN HALF CRASHES -BY FOR PLAYING H264 GOES FAST FULL VIDEO CATCHES 30 FPS.
I WANT TO KNOW WHY???????????????
AND IF THERE IS ANOTHER SIMILAR FORMAT FOR EXPORTING WITHOUT LOSING
VIDEO QUALITY

Before we go any farther, please turn of you CAPS. It makes the post very difficult to read and is considered shouting in the internet world.
Thank you.
Now,
Usually crashes in encoding can be traced back to:
1. corrupted media files
2. improper naming conventions
3. disk storage issues.
We need more information.
What format is the original material?
What Version of Final Cut Pro?
What Verison of OSX?
How many disks in the computer and how much space on the media drive? (you are keeping your media on a different drive than your OS, aren't you?)
report back,

Camera.setquality() not working for h264 encoding

Hi,
Im using H264 encoder for encoding my live video to broadcast to ios devices. But there seems a big loss in quality while using the H264 encoder. The code im using for encoding is
var h264Settings:H264VideoStreamSettings = new H264VideoStreamSettings();
    h264Settings.setProfileLevel(H264Profile.MAIN, H264Level.LEVEL_3_1);
    _ns.videoStreamSettings = h264Settings;
    camera.setQuality( 0, 100 );
    camera.setMode( 320, 240, 30, true );
    camera.setKeyFrameInterval( 15 );
    camera.setLoopback(true);
    _ns.publish("videoname?adbe-live-event=liveevent","record");
Is there any possiblity to improve my video quality or any other way of encoding the video?.
Im using flex sdk 4.6 and flash player 11.8.
Thanks in advance

Hi Jozsef,
thanks for your answer. In which version and on which date will the CBR be implemented? Flash Player 12? Or a minor release of FP11?
And until then I have no chance to have a constant bitrate? The bitrate I am passing to Camera.setQuality will just be ignored? Or is there any workaround?
Thanks and I will test using RTMFP instead of RTMP, but the CBR is the most important thing for us.
Best

Premiere h264 Encoder quality

I dare say this has been covered to a greater or lesser extent before but here goes.....
Im on Premiere Pro CS5 and I am trying to export a movie as an h264 quicktime and predictably the quality suffers even on highest quality.
Specifically my colours become somewhat de-saturated.
As I understand it (and before everyone jumps on me) this is partly/mainly down to type of h264 encoder that comes with PP.
But hey, this is a forum where the guys with the knowledge can help out those without it, so I was wondering if there were any other h264 encoders that can work through PP
and give much more faithful results (and preferably at a low file size).
Failing that, are there any h264 encoders that are standalone that people can recommend (preferably free).
Probably a tall order, but if you dont ask you dont get
Ive tried other codecs from PP but they all seem to fall down on something and I just thought by now it would be possible to get some great economic, lossless results right out of Premiere.
Thanks

I'm going to ask the viewing question from another angle since I ran into this same issue the other day.
What software were you using to evaluate the exported H.264 footage?
Here's why I ask. When my H.264 export looked weak and desaturated, one of the suggestions I found on Google was to see what it looks like in a different player. I tried a few of the ones I've got, and here are the results, using Premiere Pro CS5.5 as the reference:
Premiere Pro: Adding exported footage back into project and viewing it in the source monitor next to the program monitor, they look the same.
VLC: Matches Premiere Pro
RealPlayer: Matches Premiere Pro
NicePlayer: Matches Premiere Pro
Apple QuickTime Player 10.0 in Snow Leopard: Looks different: desaturated with lower contrast and funky color shift
Uploaded to Vimeo: Matches Premiere Pro
Well, there's a clear pattern there...if every player matches Premiere Pro except Apple's, maybe there's nothing wrong with the Premiere Pro H.264 output at all. Maybe it's a problem with playback in QuickTime Player or the QuickTime component (there's something called the QuickTime Gamma Bug that turned up when I was searching on Google, but I don't know how closely this is related). If so, that means the H.264 output file you're worried about is actually just fine.
As a result, I've started to use VLC to evaluate exported footage. (I was using QuickTime Player before.)
That's why I'm curious what you were using to view your exported clip, if it's consistent with what I found, and if others can reproduce the same results. Have you test uploaded that file to your online video host, and does it still look wrong when played back there?
By the way, I don't think a calibrated monitor is absolutely critical for this specific issue, because if you are viewing the same footage in two windows on the same monitor, they should look the same (assuming the windows are being rendered the same way). Because an uncalibrated monitor wouldn't alter just one window. If the monitor was a bit off, you should still be able to do a valid side-by-side comparison because both windows on that monitor should be off by the same amount. It just wouldn't be able to show you whether you're looking at good colors in the first place.

Hardware accelerated H264 encode

Searching around I can see there are various hardware based H264 encoder PCI cards, usually designed for windows based machines and usually aimed at the streaming media and IP markets I think.
As a long shot, has anyone designed a Mac PCI card which can integrate with a custom Quicktime H264 component for accelerated encoding?
I realise this is very unlikely, but it would be a great product. Perhaps even some form of USB 'dongle' with a small encoder chip inside - not sure how this would fit with standard QT software though. Would probably require a custom / proprietary software app to go with it.
Any thoughts?
Thanks

It all depends on the source. If you are converting a DVD, then the likely hood is that its very clean image source, so the encoder has less work to do.
I work in offline editing and our working material is lower quality and often quite grainy compared to the full res source. As a result an H.264 encode take much longer.
I have since found two products which claim to offer hardware H.264 accelerated encoding through a USB 'stick'. One is PC only:
http://www.adstech.com/products/RDX-160/intro/RDX-160_intro.asp?pid=RDX-160
...the other is not yet out, but will offer Mac support and works directly with any Quicktime supporting app - perfect!!

H264 encoded flv doesn't work

I put the h264 packets into flv file with the flv file format in video_file_format_spec_v10.pdf. I used CodecID=7(AVC) and filled video data with h264 encoded packet. But it doesn't work. The codec lib is x264 with CABAC enctropy.
The test.flv file in attachment is what I created using x264. Below is the media infomation about test.flv.
Could someone help me? Thanks very much.

First of all you can't use h264 in an flv, Flash Video files encoded with the H264 codec must have the ending (mov, mp4 or F4V)
Those need to be preparated as Adobe recommends, best choice is to use the Adobe Media Encoder or an Adobe editing tool that outputs a proper h264 file.

How to make a 720x486 file smaller in H264 encode?

Hi,
I've got a 60 second movie that I'm trying to upload, but the file size is mysteriously large at 72 MB. I sent a different 60 second movie through the H264 encoder and it was only 31 MB.
In an effort to make the large file smaller, I'm trying to change the dimensions, but I'm confused about the two types of 720x486 files. Why does is say (640x480) next to the 720x486 in the dimensions?

Try feeding your original movie thru compressor with the H.264 LAN preset - that's about 5 or 6 MB per 30 seconds.
That preset is found under Apple/Other Workflows/Web/Download/QT 7 compatible.
It does set the dimensions to 640x480 - the right sizing for converting SD pixels to square.

H264 Encoder with Media Server 3

Hi,
I am using H264 encoder from company named NVSS and I would
like to connect my stream to Flash Media Server 3.
I would like to know if this is possible or I should use only
Flash encoder 2 for that?
if it is impossible where can I get the API for that?
thanks

yes i would also like to know how can I connect my own H.264
live encoder with FMS 3. As its my own product, I am ready to make
any changes required or to be compatible with FMS 3.0.
What's the interface FMS 3.0 supports on the input side? I
some how can not find all these info, so expert please comment or
give me some useful links,
thanks,

Any insight on: interlaced 'confuses' h264 encoder?

question for encoder pros ... :
I do read in some fora, that esp. QT's h264 doesn't deliver 'good' quality, if source is interlaced (dv, 1080i, ..). in my own, simple words: due to splitting a picture into fields, the h264 doesn't 'recognizes' the vertical surrounding of a pixel, compared to a p-recording ... sounds odd, but somehow reasoned. does it?
do you know of any source, where I can read more about this?
(more of acamdemic interest, my workflow is 'progressive'-only.. )

Jeremy Hansen wrote:
... I'd be curious to read the source of what you found, ...
as mentioned: single posts in German-spoken fora (e.g. finalcutprofi.de) , no websites, .. didn't bookmark, just remembering the flow of thoughts:
• h264 is optimized or 'made for' frames.
• when the odd and even lines of a frame are stored in separate fields, the compression isn't as effective as with 'solid' frames.
.. found same 'idea' in some other threads, comparing h264 and x264 ..
.. but I have a suspicion that it is based on a fundamental misunderstanding of interlacing.
possible to share that +fundamental misunderstanding+ in two, three sentences..?
I'm no beginner, but no engineer.
I know about the historic need of interlacing, in times of aerial broadcast and tubes, and I do know, any 'flatscreen', TFT/Plasma/LED, .. doesn't use interlacing.
but this thread shouldn't compare the good&bads of i vs. p - just: can h264 handle i-sources as good as p-sources.. ?

H264 encodes white frames at end of QT movie

Hey,
Using CS3 PP on XP32 and encoding to H264 QT. AT the end of the video it is adding full white frames as if I cut to white. Does anyone know how to avoid this? Is it something that I have setup wrong?
I will be using these clips in a presentation and I need to match frame between clip to clip.
XP32, Core2 Quad 2.4, 3 Gig Ram, nVidia GeForce7600 GS, QT 7.13
Thanks!

Thanks for the reply. I wondered about that. I can't add black because I am doing match frames for a presentation. The odd thing is that the guy that is doing the presentation is on a Mac and they don't do it on his machine. So, no worries. Go figure.
Thanks
