Time to encode

I have a premiere cc sequence of 11 mts video +audio clips,each about 3.5 mins long, each involving a green screen with different jpg files beneath -- total duration of sequence:: 38 min, 36 seconds. Media Encoder cc required over 2 and 1/2 hours to encode this file. Is this a reasonable amount of time?
Thanks.

Hi,
When posting a question, please include as much information as possible. Without knowing anything about the specs of your computer, or what format you are encoding to, no one can say if the encode time is normal or not. Might be great for a 5 year old laptop, might be bad for a recent i7 machine.
Computer specs?
Video source specs?
Encoding settings? Include a screen grab from AME panel if possible
Thanks

Quick Time - H264 File encoded at 25.01FPS, but settings at 29.97 FPS Progressive NTSC. Anyone similar issue?

I work on Mac Platform. I recently encoded two 30 sec videos in Quick Time format with H264 codec. Original project is 29.97FPS Progressive NTSC 1920x1080. I encoded as usual using the same specifications. When the Quick Time was encoded, the final movie was at 25.01 FPS. Very strange. I revised my encoding settings and nothing had been changed from the original sequence.
This happened encoding directly in Premier Pro as well as sending over to Media Encoder. I then encoded the video as an MP4 and it turned out fine at 29.97 FPS. Has anyone experienced this kind of problem?

You are welcome. I'm glad you got it back up.
(1) You say you did the symbolic link. I will assume this is set correctly; it's very important that it is.
(2) I don't know what you mean by "Been feeding the [email protected] for several weeks now, 700 emails each day at least." After the initial training period, SpamAssassin doesn't learn from mail it has already processed correctly. At this point, you only need to teach SpamAssassin when it is wrong. [email protected] should only be getting spam that is being passed as clean. Likewise, [email protected] should only be getting legitimate mail that is being flagged as junk. You are redirecting mail to both [email protected] and [email protected] ... right? SpamAssassin needs both.
(3) Next, as I said before, you need to implement those "Frontline spam defense for Mac OS X Server." Once you have that done and issue "postfix reload" you can look at your SMTP log in Server Admin and watch as Postfix blocks one piece of junk mail after another. It's kind of cool.
(4) Add some SARE rules:
Visit http://www.rulesemporium.com/rules.htm and download the following rules:
70sareadult.cf
70saregenlsubj0.cf
70sareheader0.cf
70sarehtml0.cf

72sare_redirectpost
Visit http://www.rulesemporium.com/other-rules.htm and download the following rules:
backhair.cf
bogus-virus-warnings.cf
chickenpox.cf
weeds.cf
Copy these rules to /etc/mail/spamassassin/
Then stop and restart mail services.
There are other things you can do, and you'll find differing opinions about such things. In general, I think implementing the "Frontline spam defense for Mac OS X Server" and adding the SARE rules will help a lot. Good luck!

Long encoding times for footage captured with BMD H.264 Pro Recorder

Hi there,
I'm experiencing very long render times when encoding footage captured with the BMD H.264 Pro Recorder. Watching it encode (either through Premiere CS6, or AME) it looks like the encoding stops for periods of time. With other footage I can encode a 50 minute project in about 15-20 minutes, encoding with footage from the Pro Recorder is almost 1:1 in terms of project length/encode time.
The Pro Recorder uses QuickTime for H.264 captures, so don't know if that is causing issues. Don't seem to have the same issue with other H.264 formats.
System Info:
Windows 8 Enterprise (RTM)
HP Z820 with dual hexcore processors, 32GB RAM
Quadro 2000 plus Tesla for Maximus configuration
All latest updates have been installed (yesterday)
MPE is enabled for project
Also tested on a Z800 with Windows 7 and got same results
Editing the footage is fast and playback through timeline looks great. Anyone have a suggestion?
Thanks,
Jeff

QuickTime is still a 32 bit process and the 64 bit PP has to use a sort of "band-aid" to make QuickTime files work right. It's possible that might slow things down.

Varying (lenghty) encoding times :(

Hello
I have a question which has been annoying me for some time.
When I encode a given project in DVD Studio Pro (first choosing "build" then "format") I've experienced varying encoding times, from a couple of hours to 7 or even 9 hours for the exact same project and also using the same computer.
It is definately not fun for me, as a film student to sit at my school for an entire night, not knowing if my project will be finished in another hour or 4. And now I have experienced this on 3 projects altogether.
The DVD SP project consists of rougly 80 minuts material, in 10 tracks (subtitled in FCP and not plus chapters), and having 2 simple menu pages. the project fill ca. 4,4 GB in total.
On another note; I've noticed that the size of the FCP Quicktime files varies greatly in size, depending on if I choose "DV Pal Anamorphic" or "last setting" (or something) in the export to Quicktime window. Why is that so? Is theother setting a default setting or the previous setting which mysteriously compresses the files more??
On the computerscreen or a small television, I cannot see a difference in quality... And obviously a DVD SP project which has a smaller total size, takes shorter time to encode.
ANY help will be appreciated, it would be really great to know a way to keep the encoding times down to 3 hours or so
Kind Regards!
Natasha

If you are using DVD SP to build and encode the times can vary depedning on how you set the rates for the project to encode (if you changed them) whether some of the assets are already encoded (in other words there is background encoding going on or just on the build) and whether you have built the DVD before so some of the encoding for some of the sections may be done. Also where you have exported the movie to (internal drive, a seperate drive etc.) can also change the speed.
As an aside you are best off encoding outside of DVD SP and make the audio AC3. You can set up Compressor and get alot better idea of how long it takes to encode, and make sure the assets being encoded are not on the system drive and the target for encoding is also on another drive. Again depending on the settings in Compressor it can take a long time, especially with frame controls, but using some of the presets and/or not using the frame controls and it can be fast.

WM encoding times using Flip4Mac plugin - why so long?

I've done encoding for a few years now, and I've used a lot of encoders, from exporting directly out of FCP, Windows Media Encoder, Procoder, Cleaner on Mac and PC, and even Premiere.
However, I've recently been charged by my client's tech guy that my encoding hours that I estimated to do an hour long file are too long for the settings that he gave me.
First off, my tech specs are below in my profile.
My source file is a 1 hour long standard dv/ntsc file.
Here are the specifications he gave me (he usually uses Windows Media Encoder on a PC):
250K Video
· Total Bandwidth: 250,000 bps
· Audio 16 kbps, Video 125 kbps, Overhead 9kbps
· Compression:
o Audio Codec: Windows Media Audio 9 Voice
o Audio Format: 16 Kbits/s, 16000 Hz, Mono
o Video Codec: Windows Media Video 9
o 15 frames/sec
o Key Frame Interval: 7 sec
o Buffer: default
o Quality 65
o 480 x 360
So I'm exporting out of FCP quicktime conversion>windows media using the flip4mac plug-in.
I make a custom preset to replicate the settings above and I did a 1 minute test file. It took about 5 minutes for each minute of video. So for an hour long video, it would take about 5 Hours to encode. Which is about what I expected based on past experience.
I told my client this, and he was shocked that it would take so long. His tech guy proceded to tell me that it was way too long.
Now, I'm sure if I had a brand new dual-processor G5, it would be a little quicker, but does anyone have any experiece with actual times for an hour long dv clip to windows media??
I need some reassurance that I know what I'm talking about. Like I said, I've been doing this for a long time, and I've tried many different encoders on many different computers, and I've found that the flip4mac plugin is actually pretty fast and efficient.
Thanks in advance, sorry for the looooong post.
Chris

I cannot recall the exact times when encoding to WMV on my Mac, but I do remember it being much, much longer than any other export I'd done in the past.
Windows Media Encoder has always been a RT encode for me ... I do it one of two ways;
Method 1: Sony DSR-20 VTR connected to my Mac via Firewire. Analog out of the DSR-20 connected to my Windows system. Launch Windows Media Encoder, using "Capture Audio & Video." In FCP, I just playback from the Timeline or do a Print-to-Video.
Method 2: Print-to-Video in FCP to DVCam tape then play that tape back in my other DSR-20 connected via Firewire to my Windows system. Launch Windows Media Encoder using "Capture Audio & Video."

Adobe Encoder Keeps Crashing. Won't Update.

I'm working with Premier Pro 4.1.0. Everytime I try and send media to Export it does not open Encoder automatically. I need to open it and when I do I see my files ready for the Que. When I click them to render it instantly fails.
I doubt this has to do with my video settings. I'm just exporting a test video since this is my first time using Encoder. I notice that I'm running Encoder 4.0.374? I have downloaded the 4.0.1 update through encoder over and over and it when I put in my password to get it to download it says "finished" but technically it fails. It still says I'm running the oder version. So I find the downloaded driver through finder and try to manually upload it and it gives me this every time. (see photo)
Can Somebody help me out?

Can you try the following?
Close all Adobe apps and run the Adobe Updater. The updater is present on my machine @ "C:\Program Files\Common Files\Adobe\Updater6\Adobe_Updater.exe".
Does Adobe Media Encoder launch with the correct version after the update?

Adobe Media Encoder stops responding

I have Adobe CS4 master collection installed here and I've run into a serious problem trying to get it Adobe Media Encoder to do what it's meant to do...encode.
I export the project and in the initial export options window I can set everything up. I proceeed to Adobe media Encoder to finish the job and it opens and shows my video in the que, however, when I click to change the preset, or even click to start rendering, Adobe Media Encoder will simply hang forever. It just stops responding. It never used to do this.
I'm running an intel core2quad q8400 @2.66gHz
on fully updated windows 7 professional, 32 bit.
Nvidia geForce 8400 GS,
3.25 Gig useable RAM
It's not project-specific because i've tried it with another project and it does the same thing. Tried restarting, tried to reinstall Premiere pro and adobe media encoder, tried to reinstall the entire creative suite, tried the premiere-shortcut-in-the-dynamic-link-folder thing...I'm at wits end and I nearing deadline.
Anybody out there who might have conquered this problem under similiar circumstances? Please help...

When I was having this problem, I ended up having to search the entire
sequence for the problem area, a video or image that was causing the encoder
to fail. After narrowing it down to a certain section of the timeline, I
worked through elimination to find the problem video, removing one video,
image or image sequence at a time and encoding the problem area again....on
the two occasions I've had to do this, I found one corrupt video and one
large sequence of images that, which for some reason the encoder didn't
like...re-encoding the problem video and putting it back into the project
solved it for me.

If I buy quicktime 7 pro, will it help me load h.264 encoded .mov files in PREL13?

Presently in PREL13, when I attempt to playback any of a group of about 100 video clips all encoded with h.264 in a qt.mov container, they skip or halt, initially the video, then the audio as well. Rendering does not help. I installed the latest version of regular QuickTime, and the video play is the same. I don't need to do any extremely complicated editing here, but I can't really do any if I can't reliably determine start and end points, or really establish video content at all. I cannot pause or seek or really anything. It's possible that my old slow computer just can't hang. Video plays acceptably in QT regular player, seekable, pause/play works fine.
Will there be any advantage to buying the pro version? What would my work flow look like? Could I skip intermediary file steps and work from the original video files?

So unfortunately, I don't know the camera settings.
I only bought quicktime because I thought it would help me work with these videos.
Back to your initial questions shortly. In that regard, what is the file extension of these 100 videos...mov or qt?
The file extension is .mov. I didn't entirely follow the other stuff. As I said, the two programs are reporting different information about the same file.
Additionally, I can report what MediaInfo says about the same file (which seems a little more comprehensive, including for instance that it was shot on a canon, in AVCHD 1080i60:

Project Info Encoding Options?

sorry -- need to revise this post after clarifying some test results
Message was edited by: John Bertram

So if Best Quality uses a lower bitrate perhaps it should be called Less Quality
Bitrate isn't everything. A good encoder may well produce better quality with a lower bitrate than another encoder with a higher bitrate. And often good quality takes more time to encode, too.
I have done some tests and at least with that particular test material I got slightly better quality in a very few high-action scenes with Best Performance.
But since most of my DVDs are >60 minutes, I always use the Best Quality setting.
should a DVD from videotape have the same quality (good, bad or indifferent) as the original?
MPEG encoding compresses data so the quality will always suffer. But usually you don't notice it. It also depends on the input material: difficult to encode scenes include high action, noisy low-light scenes, water, smoke etc.
With Best Performance or with <75(-90) minutes' Best Quality the iDVD output quality has been OK for me.
But I'd wish iDVD used compressed audio because uncompressed PCM audio steals way too much bandwidth from video in long (90-120 min) DVDs!

Encoding to output for HDTV viewing question

I would like to know what presets are best for the most prestine output to watching an encoded clip in HD. e.g. Given a HDV input, worked in FCP 5 then then encoded. What presets encoding are going to give the best results to watch on a HD monitor, and how long should it take on a G5 dual 2 for say an hour of clip? h.264 in 1080i or 720p or Mpeg4 in 1080i or 720p... consider I don't want to wait a week for encoding. I would like to know if anyone has figured general times for encoding with these conditions.
thanks in advance

I have found the answer. In capturing in dv or hdv I can encode in DVD 4 Pro once it is imported and then selecting the encoding option by right click on the dv file and chose my preset. I watch it thru a hd monitor/tv with a dvi cable and the dvd 4.6 player and it works great. So, I found a way to gather in cable tv using a canopus advc 100 720x480 of a hd program so the res is much improved going in, then process/edit and send to DVD 4 Pro. There is some loss but for home view it works great. I did find some not so know exceptions when you go to support and look for h264 encoding help and it tells some gems about how and what presets to use. I didn't find it in the manual. Also used the latest update to DVD 4 Pro 4.02.

Generate a pulse train using a count from a quadrature encoder as the clock

I am trying to generate a pulse train with the same frequency as my quadrature encoder. Every time the encoder counts, I want the pulse to go high until the next count and then go low and so on. I am using a 6602 PCI card and a BNC 2121 accessory.

Maybe I'm not understanding your app, but I *think* you and I are approaching it from two very different directions.
As I understand it, you'd like to emit a pulse with each quad state change. Then that pulse would act as a counter Source signal. The counter will then increment on each pulse, to keep track of accumulated position. Further, you'd use your device-under-test (DUT) as a counter Gate signal, which would buffer the position count each time there's a rising edge on your DUT. The end result is a buffer of position values, captured at each rising edge of your DUT.
I'm talking about a different approach to produce the same data. You'd use 2 tasks on a M-series board. One of them is a hardware-timed digital input task based on "change detection." Each time one of the specified bits has a transition, your whole set of digital input bits can be captured and an internal "change detect pulse" is generated on the board. This task should be sensitive to the DUT edges.
The other task would be a buffered position measurement. It would receive the reference encoder inputs and internally do quad decode and keep a running count. The sampling clock for this task would be specified as the other task's "change detect pulse."
Net result: on each specified edge of your DUT, you'll buffer a reference encoder position value and a digital state of your DUT. You can choose to be sensitive to rising edges, falling edges, or (!!!!) both at once. You can also choose to be sensitive to many bits simultaneously. These are better capabilities than you get with the 6602 alone.
I *think* the 6220 should be ok, based on a quick overview of specs. I assume your 3.6 MHz is the rate of ref encoder quad state changes, right? In the approach I'm suggesting, you only need concern yourself with the rate of DUT edges which appear to be in the 10's of kHz or less.
Gotta go for now. Post back if any further questions.

Many Problems: System won't search, things taking very long time...

My G5 is having lot's of problems and I'm dreading having to reinstall the OS.
Problems:
The system won't search for files, either in the finder or in applications
The finder seems to get jammed up for long periods of time (I mean, like I can let it go for an hour and still be jammed.)
Applications like Motion run very, very sluggishly. I know that Motion is a monster program when it comes to Ram, but it's gotten worse over time.
Encoding in Motion seems to take a lot longer than it should. I've got a lot of experience encoding, so I know which files should take a long time and which shouldn't, there seems to be some problem.
I have run Tech Tool Pro (latest version) and the monthly disc utility stuff (repair disc permissions)
Anyone have any ideas that could help me? (I'll be sure and give helpful and solved points).
Thanks!
Alex

Hi, Alexander.
1. As a general check, run the Procedure specified in my "Resolving Disk, Permission, and Cache Corruption" FAQ. Perform the steps therein in the order specified.
2. See my "Tuning Mac OS X Performance" FAQ for a variety of troubleshooting and optimizing tips regarding Mac OS X performance. In particular, see the "Troubleshooting performance problems" section therein
3. re: Search. See my "Spotlight tips" FAQ. You may want to rebuild the Spotlight indices for your startup disk (I assume the search issue is in searching your startup disk). I presume by Finder being "jammed up" you're referring to Finder during search. See also "After installing Mac OS X 10.4, the computer may seem slow and the fans may run more."
After you install Tiger, Spotlight begins indexing your hard drive. If there is a white dot pulsing in the center of the magnifying glass of the Spotlight icon, it is indexing. Clicking the Spotlight icon while indexing should tell you the status and provide an estimate of how long it will take before indexing completes. It's best not to do other work during the initial indexing.
If you've been running Tiger for some time, but the Spotlight icon shows it is indexing, then something may be amiss with your current index or your drive. Indexing is very resource-intensive.
More details on "jammed up" would help.
4. See my "Problems from insufficient RAM and free hard disk space" FAQ. If your hard drive is getting full, then, despite having 4GB of RAM, the system could be thrashing. This is discussed in the FAQ.
5. See my "Troubleshooting Startup and Login Items" FAQ for steps that might help you with this problem.
6. re: Maintenance. Repair Permissions isn't maintenance. See my "Maintaining Mac OS X" FAQ. It covers my advice on "regular maintenance" and dispels some common "maintenance myths."
Good luck!

Flash video encoder slow

I'm trying to convert a 4.5 minute *.avi to *.flv and am
having some difficulty. Flash Video Encoder says I have about 15.5
hours remaining (am 0.5 hours into the process). That seems wholly
unreasonable given the fact that it took me all of maybe 5 minutes
to save it as an XviD-encoded *.avi with VirtualDub...
Any ideas as to how I can speed this up?

I'm having a similar problem - but my issue has to do with
why the time to encode on my Mac Pro is slower than on my
associate's Power Mac G5.
I'm using the Flash 8 Video Encoder to convert .mov files to
flv files on a group license. On my station I have the following:
Hardware Overview:
Model Name: Mac Pro
Model Identifier: MacPro1,1
Processor Name: Dual-Core Intel Xeon
Processor Speed: 2.66 GHz
Number Of Processors: 2
Total Number Of Cores: 4
L2 Cache (per processor): 4 MB
Memory: 12 GB
Bus Speed: 1.33 GHz
Boot ROM Version: MP11.005C.B08
SMC Version: 1.7f10
I've got 151 GB available on my system drive.
Presently, it is taking me approximately 2 hours 45 minutes
to convert a 6 minute 26 sec mov to a flv with custom settings of:
Max Date Rate: 300 kbps
Frame Rate: Same as Source
Audio Data Rate: 48 kbps (mono)
500 x 333 pixels.
HOWEVER, on an associate's computer he is able to convert
under the same specs, same files, etc. in 1 hour 40 minutes.
His computer specs are:
Power Mac G5
Processor Speed - 2.3 GHz
2-CPU's
L2 Cache - 1 mb per CPU
Memory - 16 GB
Bus Speed 1.15 GHz
My computer has much more powerful processor, so we're
confused why it's taking longer on my computer.
I also have a second internal drive but presently the
programs and source file are on my system HD. Someone suggested
that I should try to make sure that the Video Encoder has max RAM
allocated to it as well as having the scratch disk and cache set to
the second internal drive. I don't know how to do this or even if
it's possible but looking for advice and suggestions on how to
better optimize the Video Encoder and would appreciate any help
with this ASAP.
Thanks!

Premiere Pro CS5.5 encoding speed

Hi,
I noticed that the time for encoding a video in Premiere with GPU acceleration enabled doesn't change according to the shaders clock speed. The time is exactly the same with or without GPU overclocking, is this normal?
Another question: the encoding speed is faster during the first 50% of the process, then decreases a bit. Is this related to some option in the program or it's normal?
Thanks in advance.
Luis

I've made an encoding test where we can see that GPU participates more actively in the first half of the encoding process and therefore I don't understand why you said "The GPU is not involved in encoding, that is a purely CPU matter". From 50% until the end of the process CPU takes the lead.

Encoder Audio/Video Not Matching Up

I am trying to encode a 1 hour MPEG2 video file to FLV. I
have used different computers (upgrade to faster processor, 1GB
ram, but this was on a completely separate machine from previous
attempts) and different MPEG2 codecs. Every time I encode a video
the audio and video tracks do not line up. They are about 3-5
seconds away from each other. I have verified that the original
file is correct. Please advise.

Their problem is they have video at 48 kHz and audio at 44.1 kHz<<</div>
Ummm No. Video isn't measured in audio sampling rates. You probably captured video with the preset for DV NTSC 48khz (the 48khz is the audio portion). But your audio was either recorded incorrectly or from another source (CD audio perhaps?).
Use QT Pro to export the 44.1khz audio to 48 khz and import into your project - OR - use SoundTrack Pro to resample at 48khz.
