H.264 Export slow on Intel

I am trying to get an idea of the number-crunching capability of a Macbook Pro 1.8Ghz Core Duo.
I am using the Quicktime H.264 codec to convert a one minute MPEG 2 clip (HDTV, 720p).
On a Dual 2Ghz G5 PowerMac, it takes 7 minutes. The same clip and export settings on the Core Duo takes 16 minutes. What's up with that?

I would think Apple's H.264 codec would be more efficient on Apple's hardware than an open source codec. I suppose Apple's codecs are optimized for G5 at this point in time.
A lot depends on which settings are being compared to which presets. Apple tends to optimize for quality where many other applications are optimized for speed. I frequently combine many options such as multipass conversion, cropping, scaling, contrast filtering, changes to brightness, changes to saturation, change the quality preference, change volume, etc. They all take there toll on processing time.

Premiere CS5 AME Export slower than direct export?

Hello everyone,
I am testing premiere cs5 premium, and having some issues with AME export render times.
When I export media to AME it shows about 6hours to render a sequence which is 15min long.
Export settings :
H.264 1280x720 25fps
VBR, 2-Pass, Progressive
Target 8Mbps
Max 10Mbps
Input Squence is directly from AVCHD handycam with native settings no resizing but some simple color correction
However when I do the same export directly from Premiere Pro the render time drops to 38mins (which is btw also not so optimal)
My Hardware Specs:
Intel Core2Quad @ 2,40Ghz
Ram : 8GB (premiere uses 6GB)
Scratchdisk: non raid 1TB with 130Mbps average read/write
(Raw Files on Scratchdisk)
I used to export similar sequences alot faster with cs4 on the same machine..
What could cause this problem?
Thank you in advance for your answers

Thank you for your quick reply, but It couldnt solve the issue..

First of all, the remaining time indication in AME is not very accurate.
well thats also my experience, but after waiting over an hour, it was still below 25% on the scale.. so I paused and switched to direct export
Harm Millaard wrote:
Most of the time and especially with H.264 exports, there is no significant difference between direct export and AME.
Obviously in this case "most of the time" wont apply.. because I did export it directly from within Premiere 6 times faster..
There must be a problem somewhere between AME and PremierePro during reading the squence and rendering it.
Hardware Accelaration is turned on, and I have a supported Cuda Card

Embed H.264 exported videos in Powerpoint 2010

Hello,
We are using CS 5.5 on Windows 7 x64. Our videos are exported using the H.264 format.
The problem is:
We can embed the video in powerpoint (assumed quicktime is installed) but when we want to play it in the presentation, it simply shows a black screen, audio works. The weird think now is, when I fast-forward for at least one time, it works. It only shows a blackscreen if you dont fast-forward for atleast one time.
The problem could be solved, by installing the k-lite codec pack, but since we are sending presentations to other people, outside of our company, this isnt a solution.
I checked it on Windows 7 x64 and x86 with office 32 bit and quicktime, I get always the same result.
Anyone else having trouble to get their H.264 exported videos working in powerpoint 2010?
Thanks in advance
Malte

As for using the solution in post 8 above, this has problems. If you change to ipod multiplexing, then the quality of the exported video is quite a lot worse than a normal MP4. You get crawling noise on fine detail and an odd pulsing of the noise every few seconds. (This is related to the keyframe setting.) I have a video here that students shot in a forest, lots of fine detail in the tree trunk bark and all the leaves on the tree and the floor. With the Adobe YouTube H264 preset (1080p25 @ 8Mbps) the end result is fine but can only be used in Mac PowerPoint 2011 and not windows PowerPoint 2010. (2013 version has not been rolled out here.) If I repeat the export, changing only the multiplexing setting from standard to ipod then you see artefacts in the exported file. It does work in windows PowerPoint 2010, but its not a clean export.
Back to wmv for windows and mp4 for mac, until 2013 PowerPoint arrives and then we try again.

Editing H.264, exporting with current settings results in transcode?

Hello, I just edited a H.264 (.mov) home video and exported it using "Current Settings". The original file size was 400 MB but the export resulted in a 4.5 GB file. FCP X obviously transcodes the original material. I've also tried exporting the same file using the "H.264" setting, the result then was a 300 Mb file. This corresponds to the cutting I've done but the export process still took a lot of time and CPU to finish which proves transcode taking place again. In the past I used Quicktime 7 Pro to cut and edit H.264, it never transcoded the files and the saving was quick an painless. Am I missing some settings here or is FCP X currently unable to edit H.264 and export it without transcoding the original material? Thank you

Hi Badunit,
thanks a lot for this clarification. It perfectly makes sense in the way you describe it.
Maybe you can give me an additional recommendation ?
At the end I need my film in h.264 format and of course I'd like the film to be in terms of quality as close to the original material as possible. Original files are AVCHD HA (so h.264 codec with 17Mbit/s) in 1080i resolution.
So far I have exported my material directly from FCP X (using either the "export to h.264" from FCP itself but also trying several h.264 export formats from Compressor). All these attempts ended up with a quality that is visibly worse compared to the original AVCHD file, even when I use a bitrate for the output that is much higher than the 17 MBit of the original material. Resolution is fine but scenes with fast moves are really bad in some cases. From a "naive" point of view this seems strange to me: An output file in h.264 25MBit/s should be as good as the input material that was h.264 17MBit/s, shouldn't it ?
From what you stated above, I now wondered if I should better export to ProRes first (thus building what you called the "master" in best available quality) and than build the h.264 file from the master with Compressor in a second step ? means: go the way "Highly compressed" -> Master -> "Highly compressed" instead of directly doing "Highly compressed" -> "Highly compressed" ? Would there be any difference ? Or is the material anyway transcoded to ProRes in the background when exporting to h.264.
Happy to receive any recommendations / experiences on this.

H.264 export..no issues from my test

@Steven Gotz
I have tested H.264 export in CC2014 and found no apparent issues.

Have you also tested the unmultiplexed bluray profile *.m4v for import in Adobe Encore? (Encore has had problems with this m4v files some time ago and wanted to transcode them again...)

H.264 export, randomly missing audio tracks

Came across a strange issue when exporting a 1080p timeline using the H.264 export option. The first export had some strange video flickering issue, but the audio was fine. So I re-exported and switched to CBR instead of 2 pass VBR. On the 2nd export, the footage looked fine but for some reason tracks 3 and 4 which contained background audio, were not in the exported file, just silence. The thing that concerns me is the only encoding option I changed was the bitrate, and going from VBR to CBR, everything else stayed the same in the 2 exports. I have no idea why Premiere would mysteriously drop 2 of my audio tracks. Has this happened to anyone else? This problem has happened to me before, both with the flickering and missing audio. I've tried the usual updating to current version of Premiere, clearing preferences, etc. and still running into this.

I work in Broadcasting and we use Quicktime HD 1080i h264 with no problems. Plus the file sizes are just amazing (Less than 100mg for a 30 seconds)

Export slow motion from my 5s.

Hi there. I would know how to export slow-motion videos from my phone 5s to my computer without losing any quality.

I wouldn't change applications against a deadline.
Slow motion is not an easy effect to do in post unless you shot more frames per second than you needed for standard speed. Making 30 frames a second into 60 frames requires each frame to be printed twice. What were your expectations or what have your tried before?
Especially with HDV, which starts out so heavily compressed, by the time it gets slomo'd and transcoded back to MPEG2 again, yeah, I imagine it's gonna look pretty bad. You can obtain some expensive software to do the optical flow pixel interpretation without buying FCS2 but that's up to your client's needs for smooth slow motion. Rendering optical flow, we've heard, takes for freakin' ever, even on the best machines.
Some HDV users will chime in over the next few hours or days with more helpful advice.

Shutterfly iPhoto Export Assistant - for INTEL Macs

I have twice followed the directions on the shutterfly site -
http://www.shutterfly.com/downloads/features_mac.jsp
. I have uninstalled and reinstalled the plugin. It appears in my list of plugins and is checked when I go through the applications folder and get info on iPhoto. Still, when I select photos and click on export NOTHING happens - no tabs, no nothing. Suggestions?

I just got off the phone with Shutterfly tier 2 support and was told that the current Export Assistant for Intel Macs will not work with OS X version 10.4.8.
It seems to me that since 10.4.8 has been out way before the Intel compatible iPhoto Export Assistant for Shutterfly they might have tested it with the latest version of OS X. Also, there is no mention of compatability issues on the Shutterfly "Free Software" page, even though they are aware of the issue.
Additionally, the Shutterfly support pages only suggest uninstalling and reinstalling the plug-in, again with no mention of the fact that it does not work with the current version of OS X. Nice!

H.264 Exports

Hi guys, I was wondering:
Does anyone know exactly what is different between YouTube specialized h.264 exports and standard h.264 exports?

There are some minor differences, but people generally adjust them to suit their tastes anyway.
For example, the difference between YouTube and Vimeo is the bitrate.

H.264 export from AVCHD source results in slow-motion video; any ideas?

Hello, I'm trying to export a 1080i project with AVCHD footage using the H.264 Bluray profile. The resulting video looks good, but runs in slow motion. The starting footage is AVCHD 1440x1080 (1.333). When I export using the MPEG2 Bluray profile, everything runs fine. Thank you for any suggestions.

Thanks for your reply. My source footage consists of MTS files from an AVCHD camcorder. The files are 1080i anamorphic, so 1440x1080, with an aspect ration of 1.333 and a framerate of 29.97fps. I used one of the AVCHD sequence templates in Premiere CS5 that matched the video files.
I'm exorting using the H.264 Bluray preset for 1080i. I tried several of the profiles (1080p, etc), but they all end with the same bad result. The video plays, but seems to be playing at half speed. My 15-minute clip takes 30 minutes to play, even though the timline in VLC or WMP reports at 15 minutes. The audio sounds fine, but stops after 15 minutes (as it should). It's obviously out of sync, since the video is playing at half speed.
I have read a few other articles indicating it might be an issue with the way Premiere is interpreting the interlaced footage from the MTS files? This is beyond my area of knowledge.
When I encode using the MPEG-2 Bluray profile, it works fine. The video playback speed is normal.
My end goal is to edit my MTS files from the camcorder, encode using the H.264 profile, and place in an MKV container for playback on my XBMC-based HTPC. I'm also considering exporting as a high-bitrate MPEG-2, then using another encoder (HandBrake, etc.) to create the x264 MKV. Any other recommendations would be greatly appreciated. Thank you.

H.264 Export Too Damn Slow

I have a fast computer, but 3 minute HDV video is taking about 30-40 minutes to export from Premiere and AME 5.5. We need a solution guys. This will put me out of business

Pardon the brevity of my post. Just a bit of frustration I'm trying to express. Too bad there isn't a way to include my system setup into my profile so that it shows up on every post. It's a shame to have to preface every problem or question with a detailed description of my setup.
Anyway, I have a PC with the Sandy Valley I7 motherboard/processor combination in stock (not OC) configuraation. With 16 GB RAM, GeForce GTX 570 Video card, SSD system drive, 2-drive SATA RAID for captured media, another 2-drive RAID 0 for previews, pagefile. other external drives for exports. I have a Matrox MX02 Mini, but performance is simillar with or without it except for the effects rendering
The project I was referring to involves 3rd party effects such as Digital Anarchy Beauty Box and the Magic Bullet Suite. I am assuming that there lies my problem. It is the rendering time. My Matrox box does not have the h.264 accelerator.
When I have some time I will do the benchmark and post results

Block noise in CC2014 Adobe Media Encoder Quicktime H.264 Export

I would love some input from the community here. Perhaps someone else is having a similar issue.
I've been wanting to make a full switch from CS6 to CC2014, but I am experiencing a host of issues that I don't experience in CS6. For one, when I export my Canon 5DMK3 DSLR timeline using Quicktime (H.264), I get an abrasive global noise all over my rendered video as if I was using a low data rate. I use the same settings in CS6 and experience no issues.
Since YouTube compression hides these artifacts, so please download and view original file: Dropbox - RenderArtifactsQuicktimeH264.mp4

2) another codec (H.264 mp4 exports are clean)
3) all combinations of the "Use Max Render Quality" and "Render at Maximum Depth" settings
4) exporting straight from Premiere
5) rendering with and without effects (Magic Bullet Looks, sharpening)
6) GPU (CUDA) enabled and software only (on project and on Adobe Media Encoder)

I'm at a complete loss. What else could be contributing to this?

Hi Mark,
I did install the CC 2014.0.1 update and the issue remained. I had a colleague tell me that he experiences the same issue for Format= Quicktime, Codec= h.264 when he has the "limit data rate" option checked with a value. When I unchecked the limit data rate (of my standard 10,000 kbps 720p preset) I got a clean render devoid of the previously mentioned artifacts. However, it defaulted to a 70,000 kbps data rate which of course is higher than I'd like/need. For now I guess I'll be exporting .mp4 h.264, but I'm still curious why the limit data rate doesn't behave like it did in CS6.

FLV import Problem / .264 files slow

Hey,
for my work I have to use hours of .flv files daily. These are VODs from Twitch which I have to edit. Being stream related content these files often get "corrupted" because of internet connection/Twitch problems. In the .flv files this is not really a problem - most of the time you see a brief stutter but everything else is fine. Now I obviously can not import .flv files into Premiere Pro CC so I used FLV Extract to export a .aac and .264 file from the FLV container. These files import just fine into Premiere Pro but the main problem here is that when working with a .264 file the previews render VERY slow and often red frames appear. Also when exporting a file it takes MUCH time and barely uses my CPU at all (tested with other files and formats and they worked just fine).
It is also interesting to note that the .aac and .264 files have different lengths and thus get out of sync. How much depends on the source .flv file (most likely how much it got corrupted due to various reasons?)
My PC specs are 32 GB RAM, GeForce GTX760 Video Card, I7-4790 CPU & 3 7200 RPM HDDs

Now my first question would be: why has Premiere Pro such difficulties when working with these .264 files? Do I lack any codecs? Are some settings in Premiere Pro wrong? Is there any workaround or solution? As long as Premiere Pro works fine with these files I wouldn't mind them being out of sync since I can fix that manually.
I also tried using FFMPEG to change the container from .flv to .mp4 which worked and resulted in me being able to import the files into Premiere Pro but even though the video and audio track had the same length this time - they were still out of sync and much more difficult to re-sync them if at all possible so this didn't help much. I also tried video converter programs to convert to other file formats but the out of sync problem still carried over.
So as an alternative question: is there any way to convert the original .flv files properly so I am able to import and work with them? Meaning they are still in sync and keep the original quality.
The solutions should be as efficient as possible (quick) since I have to go through hours of content every day.
I am very grateful to anyone trying to help. It is VERY much appreciated. Thanks.
(for a test file you can download a flv file using www.twitchtools.com with the video link http://www.twitch.tv/trumpsc/b/537543702 - a corrupted part that ALWAYS speeds up is in the first few minutes (if you download part 7) when he opens the arena rewards when the key comes down)

I very much appreciate the help. Sorry for any lack of clarity or apparent density on my part. Up late last night.
I have a single internal drive formatted "Mac OS Extended (journaled)". It is a 160GB drive with 20GB free.
I have two maxtor FW 400 160GB drives. Each with about 80GB free. One plugged into the back of the computer, one into the front. Not daisy chained.
I have a P2 Store which connects via USB 2, and the HVX which I connect to the FW 800 port on the back of the computer.
Like I said, I've tried every conceivable combination of these devices. I've imported directly from the camera via FW to the internal drive using FCP. I've gone from the camera directly to both of the FW drives using FCP. I've also transferred from the camera, to the internal drive, then imported using FCP from the internal to the FW drive set as my scratch disc. And so forth.
But no matter what the permutation, I get the same result. And again, it doesn't seem to be an issue of moving these blocks of data around. That seems to happen just fine as far as I can tell. If I start the import, then watch the clips being created in the capture folder, they agregate just fine. It's only once they've reached their full data size (in ref'c to the original mxf files) that the import process hangs. The larger the clips, the longer the hangs (though fewer in number, obviously).
I deleted the FCP preferences and repaired permissions on my internal HDD with no alteration of the problem.
The only other observation I've had, is that when the hangups happen, and the little ball starts spinning, I also hear a high pitched whining from inside the computer case. It does not sound like usual HDD work.
Hope that I've given a better sense of the situation. Thanks for bearing with me

Nikon D600 MOV (h.264) files slow in Premiere 5.5

I'm wondering why the Nikon MOV files (h 264, 1080/30p) files stutter in Premiere 5.5. Doesns't matter if "CUDA" is turned on or off. They play back so smoothly in any other media player (Windows Media player, Quick time player, etc. and at full res.) The similar files from my Canon 7D also play back much more smoothly in Premiere 5.5. I'm wondering if the Nikon D600 is too new for Premiere 5.5 and if I need to upgrade to version 6. Any ideas? The system is running fairly fast - Win7 Pro X64, Intel 3770K (not yet accelerated, 16GB RAM).
Thanks,
Doug A

To add to Jim's remark, the reason is the .MOV extension. That causes PR to use QuiRckTime and that is a 32 bit application. It completely destroys the 64 bit nature of PR, thus reducing available memory to around 3.3 GB, even if 64 GB is installed, increasing the swapping to pagefile, slowing down your system even further.

Export slow on 12 core Mac Pro

Greetings all! I'm new to FCE and having a problem I haven't been able to find any info on.
FCE 4.0.1 is slow when exporting using Quick Time conversion. Looking at Activity Monitor, FCE appears to be evenly spread across all cores, but is only using a small amount of each core (10-14 % of the total). There's still plenty of RAM left and the Disk Activity is only about 5-7 MB.
I'm at a loss as to what the bottleneck is or if there's a setting I'm overlooking.
Thanks!

OK, I setup a simple project of a clip a little over 5 minutes long in 1080p and exported with QT conversion with the default settings. I then ran it on the Mac Pro and the Mini starting at the same time.
Apparently I my memory is fuzzy about the export I did on the Mini a month ago. The Mac Pro finished the export in 17 minutes, 50 seconds while the Mini finished in 51 minutes. While the Pro is certainly faster than the Mini, I would expect a much larger ratio than about 3:1. The mini is a Late 2009, 2.53GHZ Core 2 Duo, 4GB RAM.
When I did the first export on the Pro the other day, I saw a large projected time and went to bed. While watching this export, it seems the projected time is way off (I guess that's my noob FCE tip for today).
Still, CPU utilization is much lower on the Pro than I had expected. On the Mini the CPU is pegged at nearly 100% on both cores. The Pro did use all cores, but utilized only about a third of each core (not counting idle virtual cores) at the height of CPU activity. Disk activity also remained low, about 11 MB/second at its highest and about 6 MB/sec when the CPU was most active.
Handbrake, on the other hand utilizes around 90% of all cores (again, not counting idle virtual cores) with its h.264 encoder.
If FCE were utilizing the whole system, FCE could potentially export this test project in almost real time. But something is holding it back.
Any ideas?
Thanks!
