Compression H.264 HD

If I have HD h.264 format from my sony SR11, what compression does iDVD use? Does iDVD overwrite h.264 format.

Not sure if any of this will help you but here's what I found on this forum that you might want to read over:
Video and image formats that work with iDVD
You can use these movie and graphic formats in iDVD:
◼
Most video or image files supported by QuickTime (see the list of unsupported QuickTime formats below)
◼
16:9 widescreen formats
◼
AAC, MP3, and AIFF audio files
◼
Any format from iMovie: DV, high-definition video (HDV), MPEG-2 SD, MPEG-2 SD, MPEG-4 SD, MPEG-4 HD, and AVCHD
High definition video is converted to work with the format of your project. iDVD supports using 16:9 widescreen video; therefore, when your DVD plays on a DVD player that supports widescreen format, the footage appears in its original aspect ratio.
The following video and image formats are not supported in iDVD:
◼
Copyrighted or protected videos.
◼
Movies saved in thousands of colors using the “none” compression setting in iMovie.
◼
48-bit color images (16 bits per color). To use source files in one of these formats in iDVD, save them in a supported format.
◼
Aurora uncompressed files. For best results, export Aurora clips as DV-format video before importing them into iDVD.
◼
QuickTime VR, MPEG-1 or MPEG-2, Flash, streaming or encrypted movies, or QuickTime spanned movies. You can’t add MPEG-1 or MPEG-2 files to an iDVD project because they don’t contain standard video tracks.
◼
QuickTime Fast Start movies. (Fast Start movies are intended for Internet playback.) When saving a QuickTime movie for use with iDVD, click the Options button in the QuickTime Export dialog and make sure that the “Prepare for Internet Streaming” checkbox is not selected.
NOTE: You can add any type of file to the DVD-ROM portion of your DVD so that viewers can copy the file to a computer. Viewers can access these files only when viewing the DVD in a computer, not a DVD player connected to a TV.

Compressed H.264.mov format not recognized in DVD pro?!

Hi,
I just compressed my 12 minute HD film using the "create a DVD" 90 min HD setting in compressor. That resulted in two files, one is a Dolby Digital Professional 2.0.ac3 audio file and is recognized in DVD pro, while the other is the video file H.264 6.75Mbps.mov.
Here are the video file specs:
Quicktime movie
615.6 MB on disk
Dimensions:
Codecs: H.264, Linear PCM, Timecode
Dimensions: 1920 × 1080
Audio channels 2
I tried using the regular 90min setting but I was seeing a loss in quality. I'd like to burn a good quality dvd using the compressed files, but I can't import the video file into DVD. I would greatly appreciate any help/suggestions. Thank you so much!

The conversion in scale from 1080 to 480 is probably the most frequent cause of quality dissatisfaction. Because you are inputting a 1080 file, Compressor will automatically turn on Frame Controls (which is accessed via the Inspector). Open Frame Contols. IMO, the Resize Filter should routinely be set to Best for jobs like this.
Also in the Inspector, go to Encoding>Quality and check the bit rate is set to 7.7 Mbps. If it is (and it should have defaulted to that rate, leave it unchanged.
Open Preview and mark in and out points for a short representative section of your movie. Then submit.
In DVDSP open up Preferences and verify that your Project Setting is SD DVD. Verify in General that display mode is 16:9 Letterbox.
Bring the two files into DVDSP. Use the Graphical view to delete the menu icon. Control click on the Track icon and select First Play. Build and then either waste a blank DVD-R or use and reuse a DVD-RW for the quality test. Then Format. When the DVD has been burned, evaluate by playing from your player to your TV.
Hopefully you'll like the result and can then proceed to complete the full project.

Compressor 3 taking far too long to compress H.264

Origianally posted this here:
http://discussions.apple.com/thread.jspa?messageID=7328851&#7328851
But thought I would start a new topic.
Something is very wrong. I sent a 9 minute MPEG-2 file to Compressor to have compressed to H.264. (H.264 compression is what I would gather many of us are using Comp for in the first place).
I know Compressor can do H.264 comp at about 1.43:1 from tests. So a 9 minute clip should take, 6 minutes or so, and with Q Master it should be even faster. Well, Comp reports 8-9 hours. What the heck is going on.
I have taken MPEG Stream Clip and done the same H.264 output and it takes about 6-7 minutes. Something is up with Comp 3.
Now I have turned off Q Master, Reset the Comp 3 BG Processing, Quit Comp and relaunch, maybe reboot, possibly trash all prefs related to Comp.
And still 8-9 hours?
A 9 minute clip should take 6 minutes and as I say, with Q Master, even faster, that is the point of Q Q Master services

Took me awhile to get Compressor going reliably but now it has been pretty solid.
I am not sure what settings you are using to encode (for instance Frame Controls can add alot of time), but 8-9 hours for 9 Minutes seems rather extreme. Note though that you are using an MPEG-2 (m2v?) file. You may be better off converting to another Codec or better yet go to the source material you are double encoding.
I just set up a Compressor setting on an Octo 2.8 with everything pushed to the Max on Frame Controls and set to resize a 6 Minute HD AIC stream down to H.264 @25% of the size of the original and sent out to "This Computer" and not the Cluster and it took 17 minutes or so. Even with converting from m2v it does seem like it is taking way too long on the machine for you.
I saw you had done some troubleshooting, but do you have any other details? Was his a clean install of the OS and Studio, or were there upgrades along the way? That caused some issues in the past - meaning between upgrades to Leopard and/or installing Studio 2 over Studio 1.

Compression settings for H.264

Can anyone recommend some settings for making making H.264 video intended for delivery on the web at 640x380?
Thanks.

Heya Rick,
So I was looking at the H.264 settings in Compressor and it would seem as though the highest bitrate is 1500 kps so guess you can't do bit rate between 2000 and 2500 k/bits like another poster recommended by using Compressor for Apple Devices settings. Also there isn't much control over the audio of the h.264 file in Compressor whereas QT conversion from FCP allows you to select a mono audio file with a lower khz rate and render quality.
The difference between selecting stereo vs. mono will be the difference between 1/2 or twice the filesize for your audio file which will absolutely affect your total filesize but make little to no difference in your viewed file intended for web viewing. Take a look at a standalone Stereo track AAC 44.100 kHz 192 kbps that is 5 mins long and you're looking at about 5 MB file just for the audio!!! Cut that to mono and drop the frequency and bitrate and that 5 mb audio file will be about 1MB.
I have always used QT conversion from FCP and have only just now had the opportunity to look at the h.264 settings in Compressor and judging from initial impressions I would go with QT conversion from FCP.
For the video you mention I would just go with export using QT conversion from FCP. For video settings use automatic keyframes with an automatic datarate with quality set to Medium. Best quality multi-pass encode. For sound settings use Linear PCM Mono channel 32 khz rate and Faster Quality render setting. That should give you a nice, small file size that will look and sound good enough for sit down interview video between 3-5 mins. in length.
Also remember that the h.264 can be used with a Flash player instead of QT player so those without Quicktime can view the file without having to install the QT player. You can use something like the JW Player from http://LongTailvideo.com or simply change the extension of the compressed h.264 to .flv and use it with any Flash Player above 9.0

Best settings for highest quality for exporting a .mov file to h.264

Hi,
I want to know what the best settings are for the highest quality for exporting a .mov file (720p50) to h.264. I want the same quality as the original.
I want to know the data rate etc.
regards,
Jeroen
Message was edited by: Woudgraaf-AV

There is no way to get the exact same quality when transcoding from an editing source to a highly compressed H.264 QT. However, you can get a real high quality by adjusting the data rate.
However, these things depend on the length of the original. I routinely encode H.264s with good results in the 3000-5000 data rate range. I also make sure that I use multiple pass encoding. Take a short snippet of your project (10 seconds or so), and try various bit rates until you have one you like that doesn't take forever.

H.264 problems...

When I click file - share - select quicktime icon - select expert settings - followed by now saving where ever and making the "export" as "movie to quicktime movie" and "use" as "broadband - high"
These settings make a not to compressed H.264 movie. And sometimes the movies work whereas other times I simply get a movie that plays and about half-way through the video freezes and now only audio plays. Has anyone else had this problem? Any fix for it?
Thank you,
TM

Do you have one of these movies (short) I can download and look at?

Import 1080p h.264 mov to editi with premiere pro?

i am a nikon d800 user , and i like to use adobe premiere pro to edit the 1080p video clips for sharing with my friends, but the compressed H.264 MOV videos from D800 can not be playbacked or edited smoothly on many editing softwares such as Adobe Premiere Pro, Sony Vegas , Windows Moive Maker and so on.
With the help of my friend Tim, i got a top video converter, it works very well .
if you wanna to got the more detailed information , you can refer here:
Nikon 1080P H.264 MOV imported to edit with Adobe Premiere Pro

What version of Premiere Pro are you using? I had no trouble whatsoever importing or editing a video off of my D800 in Premiere Pro CS6. No type of conversion was necessary.
As far as the playback, without NVidia's CUDA hardware acceleration for Adobe's Mercury Playback Engine, software acceleration is not going to keep up at 30 fps. Change the playback resolution to 1/2 (every other frame) for smooth video playback. This is for display purposes only. The video itself will still be fully processed.

Capture in prores proxy or H.264

So here's the qusetion, I'm capturing footage from a HD broadcast (from cable, TWC), being that it's already a compressed signaled would it better to capture it as pro res proxy or a high bit rate H.264? ProRES 422, LT, just seems like overkill. Which would give me better qaulity?

appleconfuse, i would like to help answer your questions, and i hope that what i say is helpful to you from a professional that knows how this works. :-) you should never use anything higher quality than h.264 for recording a tv show from tv. its completely ridiculous to use prores to do this for the following reasons.
1.) i work at a tv station, and i can personally testify that tv shows are already compressed into h.264 at my station. so by the time it reaches you its already in h.264 anyways.
2.) once a video is in a compressed format, it is 100% impossible to add the removed information back into the video feed by encoding it in a higher quality format. it is also impossible to make a 1080p video signal into a 4k video signal just by upscaling it.
3.) prores is meant ONLY for creative professional to create content, not for viewing or storing for personal use. this is not what it was meant for. h.264 is a consumer format intended for the everyday use and will be much more friendly for your purposes. ;-)
you are not making the video better in any way at all by encoding it in prores proxy. the compression process they use to send a video out over the internet either on youtube or at a tv station is already highly compressed h.264. i know this because its my job to receive the video signals as h.264 video files and then to compress/encode them AGAIN before they are broadcast.
i hope this is helpful to you and i certainly am sorry to break this news to you. but unfortunately all you are doing is taking up more space on your hard drive and creating unnecessary work for yourself. to clarify, 4:2:2 footage is completely useless to you unless you are actually color grading footage. otherwise you receive zero benefit from it.

Interlacing/combing on HDV QT export, worsened with Compressor H.264

Greetings,
I have created a 10 minute video of a child moving back and forth against a black background. The material is HDV, captured and edited as HDV in FCP 7 with Pro-Res renders, and exported as QT using "Current Settings." In the exported QT, I see that the material is interlaced, although the "combing" effect of the interlacing isn't terribly noticeable. (although I'd rather have NO interlacing without affecting resolution.)
But Then, the final output of the video is intended for a wireless media player, playing the movie as a data file. I was told the media player needed a .mov file encoded with H.264 compression. When I do this, the interlacing/combing becomes REALLY apparent on the edges of anything moving in the video-- and is especially amplified becaise the child is against black-- so the limbs and edges of the kid look really jagged.
Currently I am exporting two 5-minute QT's that need to be put together with additional elements to make up the final 10 minute piece. I am putting both 5 min QT's into another HDV sequence before my final QT export. Would I have any initial success in not having interlaced edges if I put those two QT's into a ProRes sequence instead? And if so, would it be ProRes 422 HQ 1080i? Or would changing the setting to "P" help get rid of the interlacing, and keep all the digital information?
OR, should I try to get rid of the interlacing in Compressor? As I said, when I tried this initially, the "combing" got worse.
The settings I used in Compressor were:
Compression H.264, leaving size and data rate and key frames all "current/automatic" (compression set to "best")
Frame Controls set to "on"
Output fields "same as source"
De-interlace set to "best"
Adaptive details checked.
The video is playing on a 42 inch flat panel monitor and WD a Live Plus media player.
I think the monitor is 1080p?? Perhaps I need to get rid of the interlacing because it is a flatscreen, progressive monitor?
Thanks for your help. It is currently playing on the above equipment at the gallery and looks terrible so I need to fix asap.
Amy

Michael,
I just wanted to sum up what I ended up doing, for others folowing the post:
So I did three tests, and I will post settings and results below. Setting the de-interlace to "progressive" did do the trick, the "combing" effect went away.
The settings above, with H.264 codec, and leaving size/frame rate etc. as same as source, gave the best results visually in picture. Playback was good, I saw one or two tiny "skips" like a little stutter, barely noticeable. Quality was set to "best." This was only a 3-miute clip of the 10 minute piece, and render times were over 11 hours. So when I do the whole piece I'm wondering if I should adjust any of the settings. I'd like to get just as good of results but with less render time. Any ideas?
Thank you again,
Amy

How to take advantage of H.264 video streaming of webcam BCC950

We used flex 4.6 to develop an web app using Logitech webcam of BCC950, We used Graphedit of Directdraw to know BCC950 has pin 0 to support i320,RGB24,and mjpg stream, and pin 3 to support H.264 stream. We also set h264videostreamingsettings in as code to ask for H.264 data directly from the webcam, but from the CPU consuming we can judge flash player only fetch pin 0 uncompressed data instead of H.264 data directly. We need to take advantage of BCC950 H.264 support to get webcam hardware compressed H.264 streaming data to avoid compression by CPU/software. As we know flash does not give programmers choice to define the pin to get data, then what we need to do to make sure we can get H.264 video stream from the webcam directly? thanks. Henry

...well I did follow that article on playing an h264/mpeg4
video in flash. It works well, but how would you add playback
controls?
FLVPlayback component only allows you to source an FLV video
not h264/mpeg4.
This is probably a simple as3 answer...but I am not
knowledgeable on as3 to know what code to add.
Any suggests or direction that I should look would be great.
In the meantime I am researching actionscript 3 to find and anwer.

CD-R Delivery using H.264

Trying to refine iMovie's Expert settings to allow a 15 minute video to be exported to CD-R media.
The exported .mov is too large for CD-ROM; must retain quality!
Is this goal possible?
.mov = 1.13 GB / 15 min. duration
H.264 / High Quality / 720 x 480
fps: 29.97 (Current)
Key Frame Rate: 24
Data Rate: 10.38 mbits/sec (Automatic)
Optimized for: CD-ROM ???
Frame Reordering: yes
Encoding Mode: multi-pass

QTKirk:
Here is my latest effort with the Expert Settings; I came close with the H.264 codec but need to continue tweaking until I can get the 15 min. video onto a 700 MB CD-R, and retain quality.
.mov = 721 MB --> very good quality output (titles & video); six hour compression
H.264 / High Quality / 720 x 480
fps: 15
Key Frame Rate: 24
Data Rate: 5000 kbits/sec
Optimized for: CD-ROM
Frame Reordering: yes
Encoding Mode: multi-pass
==============================
.mov = 506 MB --> frame stutter is unacceptable (titles & video comparable to H.264); five hour compression
H.264 (x264) / Medium Quality / 720 x 480
fps: 15
Key Frame Rate: 24
Data Rate: 5000 kbits/sec
Optimized for: CD-ROM ???
Frame Reordering: yes
Encoding Mode: multi-pass

Editing iPhone video without loss of quality

I've a stack of video clips taken from my iPhone 3GS which I want to simply stitch together and edit down a little WITHOUT loss of quality.
All I want to do is import, crop and stitch them together, thus create a single file *with no change in image quality*. (for smaller projects, I used to do this kind of thing in older versions of QuickTime Pro.)
What is the best procedure for this in iMovie 09? Indeed, can it be done?
My understanding is that ANY re-compression will result in artefacts and loss in quality.
Further info...
I've managed to import the clips ok (making sure any options to 'optimise' anything are turned off) and edit them together in iMovie. This way, the import is fast and the images seems untouched, so I assumed no conversion has been done on the video (I think I'm wrong here?)
(Setting the project aspect ratio to 4:3 was the other gotcha.)
Having sorted the above out, and done some editing, I now want to export to a single file. I understand the iPhone codec is H264. However, when I export (via quicktime) and select H264, it wants to re-compress. I worry this will loose quality.
When I export with lossless compression, of course I get a 150G file - owch. The sum total size of the originals are 2.63G
Any suggestions?

iMovie will re-compress. To me this is a small price to pay for having an edited movie. Personally, I would optimize, but if you keep your movies simple, you will be OK without. If you decide to apply image stabilization or speed changes, you will definitely need to optimize. Optimization resolves the highly compressed h.264 frames into full frames in Apple Intermediate Codec.
While the quality loss you may experience is not likely to be visible to the naked eye, if that is your only criterion, then avoid iMovie and follow QuickTime Kirk's advice.
Here is a [sample video|http://vimeo.com/7093442] that I made in a Dentist Office. You can see what the re-compression looks like. In this case, I did not optimize.
Editing in iMovie is non-destructive, so you can try it both ways (imovie and QuickTime Pro) and see if you can tell the difference.

Can you render clips / transitions

I have a new Mac that is very very fast. However, even still some video transitions don't play smoothly.
I can export the whole project into a quicktime movie or .m4v file and see them smoothly, but I cannot see them play smoothly in iMovie.
Is there a way for iMovie to pre-render effects and transitions so that they don't have to be generated in real time (that is too slow for real time)...?
(Many of the source files I'm working with are .m4v files, which could be why the transitions are playing back poorly.)

You can convert the m4v files to Apple Intermediate Codec. That would convert the highly compressed h.264 into full i-frames. You can optimize the clips from within iMovie, or you can do this in MPEG Streamclip or QuickTime Pro.

Media Encoder/Premiere Export Crashing During long file exports

I'm running Premiere Pro CC 2014 on a windows 7 computer--a Livestream Studio HD500. I use the computer to capture live video, which is saved as large AVI motion-jpeg files. I need to edit and export these files as compressed h.264 videos for upload to the web.
I am able to import these files into premiere and work with them, but the program crashes to desktop during any long export. I am able to export very short (1 or 2 minute) videos just fine, but anything longer will crash to desktop after a few minutes of processing. Media encoder also crashes when attempting to compress the videos prior to processing.
I have been able to circumvent this problem by compressing the files I'm working with in advance using virtualdub, but it adds an annoying step to the workflow that I'd like to eliminate. Shouldn't premiere be able to import, edit, and export compressed versions of these files without crashing?
Note: I've tried turning off GPU rendering and clearing my cache several times.
Thoughts? Much appreciated.

Maybe this problem?

Media Encoder is not producing sharp .mp4 exports, any help please?

Hi all, I've been trying for a while now to export my After Effects CC 2014 project using Media Encoder CC 2014 as a MP4 file. I've chosen 'match source' settings, VBR 2 pass with various bitrates (even extremely high bitrate values) but my video is still not sharp. I've experimented with making the frame rate also higher but that doesn't make a difference. I've also tried using the 'Maximum render quality' option but that also doesn't help.
In the 'output' preview, the images look sharp like in the original project. But I can't get this in my final file. Anyone know why? Thank you very much.
Here are my settings:

MPEG compression (h.264 is MPEG) has a limited color space, compresses color, and has specific frame sizes that are required. Also, your media player has limitations and scaling problems. So do web pages. Nothing is perfect. The green text against the bluish background is going to look bad when you throw in compression artifacts from color and the fringes around the green text against the white background are also color compression artifacts. The solution is to first, modify the design to colors that work. You have to be sensitive to the color requirements of the space you are working in wither it is TV, WEB, Print or any other media. Most of these problems are color compression artifacts caused by the limited color space and limitations of MPEG compression.
The best hope for a design like this test to work is to first, make sure that your output is a legal h.264 size, second choose colors that will work against white backgrounds, third render a lossless master and finally, use that lossless master as the source for your MPEG compression in AME. You also make sure that your media player is not scaling the video.
If you absolutely have to have the video 392 X 640 then you are going to have resizing artifacts with H.264. You either have to accept that or change design of the web page and the HTML 5 code for the player. You also need to consider HR displays like the Retina displays on Macs or 4K displays on Windows machines or the displays on new mobile devices because they are going to want to see video and images that are 2X as big as a standard display. You'll also have to code for HR displays in your HTML. If this were my project I would make the master comp the nearest 2X the size needed for a standard web page that was a supported h.264 frame size, carefully choose my colors and design with known limitations in mind, render a lossless master in 10 bit or better 444 color, then send that to AME for compression. The web page would then be designed and the player coded with the video size taken into consideration.
