H.264 encoding for export - CS4

Does higher bitrate encoding equal higher quality results in all instances?
I can of course see increased bitrate encoding reflected in
incrementally larger file sizes, but the quality difference
seems to be much more subtle.
thanks

My understanding of how material is broadcast these days is no matter what
you supply to the broadcaster... it is going to be "converted to something more
convenient for them to "send" to air. Especially so with satellite where bandwidth is a
bigger issue. Much broadcast media is file streamed from servers so understandeably the files sizes are eventually reduced.
I provide uncompressed avi and movs that in the final out come..., I know are broadcast at some level of MPEG.
eg 30 second HD TVCs at 2GB files become 50mb mpegs.
My rationale is that give them the highest quality possible and let any degredation occur their end ( where I have no control)

Have plan feature H.264 Encoding for Cameras on Mobile?
Thank you

Generally speaking H264 is supposed to be about twice as efficient as MPEG2. I think that's probably overstating the case somewhat (i.e. H264 isn't really twice as "good"). However you can certainly cut back somewhat from what you'd use with MPEG2.
Next consideration is the resolution/dimension of the final video. Do you want to go 640x480 (NTSC 4:3 aspect ratio) or something smaller? Since you're starting with video tape I'd suggest something like 480x360 (that should be large enough by a good margin to get all of the quality from a video tape). However, you might even want to drop down to 320x240 since that would be compatible with the video iPod and potentially other mobile, hand-held devices.
Finally, if you go with 640x480 I'd suggest something in the 3Mb to 4Mb per second range (for relatively demanding material, less for so-called "talking heads," and perhaps a bit more for extreme action), that would scale to 1.7Mb to 2.3Mb per second for 480x360, and 750Kb to 1Mb per second for 320x240. If you plan on using Front Row and want to store your video on a remote server (accessed either wirelessly or over ethernet) then you will definitely want to enable the "streaming" option when you encode the video. In fact you may want to use the streaming option in every case (for future compatibility).
If you plan on viewing this video on a computer display or any type of LCD or high-definition device you may also want to consider a de-interlace step for the 640x480 and 480x360 resolutions. You won't need that for the 320x240 video since 240 is exactly one half of the vertical resolution for standard NTSC DV (720x480). However, if you're using PAL you'll need to adjust all of the above resolutions to fit the proper form factors.
As always, the beauty will be in the eye of the beholder. Thus I'd suggest that you try something near the above and adjust accordingly (based upon what you see and like or dislike).

H.264 Encoding Problem in CS4

Hey guys!
For some reason I'm not able to encode my video at the desired bitrate of 12 Mbps. Instead, Adobe Premier Pro CS4 wants encodes my videos at the default bitrate of 34.98 Mbps. Is this a common issue or am I doing something wrong? Here are the screenshots of my encoding settings:

Try switching to CBR to set your bit rate, then switch back to VBR and
set the same bit rate. The settings should stick after that.

H.264 Encoding for TV

I have a bunch of old videos and would like to encode them for watching on TV via Front Row (or similar) using H.264.
What would be a good data rate for this?

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

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/AVC software encoding for cameras

Hi All,
             Please let me know, how can we activate H.264/AVC video encoding (new feature in Flash player 11 [H.264/AVC software encoding for cameras]) using actionscript 3 in AIR application, I think, it could not be by default as there are no updates available for flash builder 4.5. So, how can we pick the encoding option. Any new API or methodology for this?
Any one any idea??

H.264/AVC software encoding is not turn on by default. You need to assign the NetStream.videoStreamSettings property an H264VideoStreamSettings object. Here's a very simple example;
package
          import flash.display.Sprite;
          import flash.events.NetStatusEvent;
          import flash.media.Camera;
          import flash.media.H264VideoStreamSettings;
          import flash.net.NetConnection;
          import flash.net.NetStream;
          public class TestAVC extends Sprite
                    private var _nc:NetConnection;
                    private var _ns:NetStream;
                    private var _camera:Camera;
                    private var _h264Settings:H264VideoStreamSettings;
                    public function TestAVC()
                              _h264Settings = new H264VideoStreamSettings();
                              _nc = new NetConnection();
                              _nc.client = this;
                              _nc.addEventListener(NetStatusEvent.NET_STATUS, onNetStatus);
                              _nc.connect("some fms server");
                              _camera = Camera.getCamera();
                    private function onNetStatus(e:NetStatusEvent):void
                              switch (e.info.code) {
case "NetConnection.Connect.Success":
                                                  _ns = new NetStream(_nc);
                                                  _ns.addEventListener(NetStatusEvent.NET_STATUS, onNetStatus);
                                                  _ns.client = this;
                                                  _ns.attachCamera(_camera);
                                                  _ns.videoStreamSettings = _h264Settings;
                                                  _ns.publish("testAVC");
                                                  break;

Please clarify availability of H 264 encoding in AIR for iOS/Android

Hello,
I've written an app to send a live camera stream via RTMP in H 264/Nellymoser from mobile devices. The app works fine on AIR when tested on my Win7 desktop, but when I publish to AIR 3.2 for Android or AIR for iOS, it seems that the H264VideoStreamSettings are simply ignored and the video ends up in Sorenson. Is H264 supported for encoding/publishing on AIR for mobile devices? If not, is this planned for the future?
Thanks!

Unfortunately, the release notes say H.264 encoding from AIR is for the desktop version only:

There's something else going on. When you search, the search box searches the Spotlight database that it created when indexing. It doesn't search the computer again. I suspect a hosed index. System Preferences->Spotlight->Privacy->delete all volumes and readd them back in. That should reindex the computer and all attached HDs. BTW, by default there are many places Spotlight doesn't return information from, mainly the various Library folders and the System folder. If you want to find everything, do this:
Click on the Desktop, CMD+F, click on Kind button, select Other, drill down to File invisible, check it, continue down to System files, check it, and click OK. Now, click on + button, click on the left-hand item and select System files and select are included, click on the plus button, click on the left-hand item and select File visibility and select visible or invisible, select File Name, save the search, drag its icon to the Dock, and use to search your entire Mac—currently starts with By Name, but Contents is available. I use this instead of CMD+F or CMD+spacebar for all searches.

Help! Best SD export settings for web CS4

Hello and thank you in advance for your help. I'm a newbie here and have read through many posts on exporting and found some good information here for creating a master http://forums.adobe.com/message/3005601. But, I am searching for export settings to send a 3:30 min. video to a client to upload to a website and you tube that is high resolution but not too huge of a file. I am looking for setting others have used to create this.
This is a SD tutorial video with a combination of .psd and .jpeg stills and graphics in After Effects compositions mixed in video footage. There are a lot of cross-dissolve transitions and I am getting pixelization with the settings below. It is a start, but I hope to get a smoother video for the web at 320x240 and 720x480. Any suggestions on aspect ratio, file format and settings would be appreciated. The original video is 720x480.
Format: H.264

Support for NVidia GPU hardware H.264 encoder (NVENC)?

The latest NVidia GPU architecture, Kepler, now has a dedicated hardware H264 acceleration block, NVENC.
It is similar in function/purpose to "Intel's Quicksync" (except that Quicksync works with more codecs: MPEG-2, VC-1, and H264. NVENC only supports H264 encoding.) The company claims the hardware-block can encode 1080p video much faster than the host-CPU alone (probably at the loss of some image quality.) This feature is supported on desktop NVidia GPUs with the model GT640, GTX6xx. And in laptop NVidia GPUs GT640M, GT650M, GT680M (and a few others.)
Does Premiere Pro CS6 take advantage of NVENC? If not, are there any third-party plugins that add NVENC-support to CS6?
If not, I'd like to try writing a plugin that uses NVENC, though that'd definitely be an ambituous undertaking!

I have finished a 'proof-of-concept' NVENC Exporter plugin for CS6. This took much longer than I thought it would (mostly due to my inexperience in interacting with Adobe's 'suite' API.) And the beta-plugin is very rough around the edges (no audio or muxing support), and needs some further speed-optimizations, but works well enough for me to start basic testing and behavior characterization.
The following comments are based on my proof-of-concept NVENC-exporter plugin, run on a Geforce GTX650 1GB. The plugin is compiled from the NVidia NVENC Public Beta SDK 2.0 (Dec 2012) and Geforce 314.07 drivers (Feb 2013). The programmer-API to access NVENC is protected by a license-key. The SDK comes with a free trial-key, but doesn't indicate how it compares to a (purchased) retail-key (i.e. does it perform the same but with restricted features/functionality, or does a retail-key offer higher quality encodes?)
First off, how is the video image-quality (compared to the MainConcept H264 that Adobe bundles with CS6)? Based on naked-eye comparisons, NVENC is anywhere from slightly to somewhat worse. As such, since the quality delta was easily discernable at all bitrates, I didn't find it necessary to take objective psnr measurements.
(1) At "low bitrates" (eg. 6mbps or less at 1920x1080 24fps), NVENC is noticeably worse than Mainconcept. The fixed GOP-pattern (group-of-picture) really kills the output-video at scene-transitions, because the encoder doesn't make intelligent decisions about where to place reference-frames.
(2) At "high bitrates" (eg. ~25mbps for 1920x1080 24fps), NVENC is slightly worse than Mainconcept, though now the two are almost neck-to-neck. NVENC seems to have problems tracking very subtle color transitions. For example, on animated/computer-generated scenery (like a Disney cartoon), NVENC had shows a tendency to introduce blocking artificats into sky gradients and other tonal-gradients. Mainconcept was much better in this regard.
Next, what about speed? Speedwise, NVENC easily wins (as expected.)
(3a) For 1080p video, NVENC consistently finished straight "media-export" jobs in Adobe Media Encoder (i.e. straight "in to out" without any adjustments/changes to the source video) roughly 3x faster than the Mainconcept H264-Bluray codec. For example, NVENC needed 30 seconds to re-encoded a 120second Bluray clip. Mainconcept usually took 90 seconds. (Both encodes were single-pass VBR; run as video-only, no audio, no muxing.)
(3b) for 3840x2160 video, NVENC's speed-advantage shrinks to roughly 2x. (This is likely due to a very slow hostmem-hostmem frame-copy operation inside my plugin.)
(4) NVENC CPU-usage hovers between 30-40% during the Adobe Media Encoder session. Mainconcept always used near 90-100% CPU. (My machine is an Intel i5-3570K 4-core CPU.) If someone were comparing NVENC/Mainconcept on a 2-core laptop, the speed-difference would be closer to 6x. Even so, NVENC falls behind Intel's "QuickSync" technology (unfortunately, Intel doesn't offer a Quicksync exporter-plugin for CS6.)
In summary, in its current state NVENC isn't good enough to replace MainConcept in the content mastering and final encode process. But many users may find it useful as a 'quick preview tool'; to generate fast encodes for a bunch of different edit/cut tests (with the intention of throwing most of them away.)

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?

Best practice for exporting from iMovie '08 to iDVD

I am looking to find out what is the best practice for exporting from iMovie '08 to iDVD. I have read the other postings that give the basic howto (export to Media Browser then select the video in iDVD). However, my question is a little more technical. I have 1080i HD projects. I am interested in burning them to DVD in the best possible quality. What setting should I be using when I publish to Media Browser?
I am wondering about quality loss due to more than one conversion/compression. I suspect that when I export to the Media Browser then this is occurring. If I am not mistaken iMovie is using something like H.264 for this. Then, when I run iDVD I suspect it will it do another conversion/compression, I think to get to MPEG2. Not only could this result in a loss of quality but also it will take extra time. I am interested to know what others think about this.
Finally, I am looking to create DVDs for a lot of video. I am wondering if there are any USB or firewire hardware devices out there that could speed up the compression. I use the Elgato Turbo.264 when I want to encode to H.264 but I wonder if there is something similar for DVD creation.
Thanks in advance.

the standards for videoDVD are 720x480, and usually mpeg2 encoded..
so, your HiDef project HAS to be 'downsampled' somehow..
I would Export with Qucktime/apple intermediate => which is the 'format' your project is allready, and you avoid any useless 'inbetween encoding'..
iDVD will 'swallow' this huge export file - don't mind: iDVD cares for length, not size.
iDVD will then convert into DVD-standards..
you can 'raise' quality, by using projects <60min - this sets iDVD automatically to highest technical possible bitrate
hint: judge pic quality on a DVDplayer + TV.. not on your computer (DVDs are meant for TVdelivery)

Best Practices for Export

I have recently begun working with a few AIC-encoded home movie files in FCPX. My goal is to compress them using h.264 for viewing on computer screens. I had a few questions about the best practices for exporting these files, as I haven't worked with editing software in quite some time.
1) Is it always recommended that I encode my video in the same resolution as its source? For example, some of my video was shot at 1440x1080, which I can only assume is anamorphic. I originally tried to export at 1920x1080 but then changed my mind as I assumed the 1440x1080 would just stretch naturally. Does this sound right?
2) FCPX is telling me that a few of my files are in 1080i. I'd like to encode them in 1080p as it tends to look better on computer screens. In FCPX, is it as simple as dragging my interlaced footage into a progressive timline and then exporting? I've heard about checking the "de-interlace" box under clip settings and then doubling the framerate but that seemed to make my video look worse.
3) I've heard that it might be better practice to export my projects as master files and then encode h.264 in Compressor. Is there any truth to this? Might it be better for the interlaced to progressive conversion as well?
Any assistance is greatly appreciated.

1) yes. 1440 will display ax 1920.
2) put everything in a 1080p project.
3) Compressor will give you more options for control. The h264 from FCP is a very high data rate and makes large files.
