Encoding Video

I go through my video and set luminosity and color in Premiere Pro 5.0. Then I export the video using Adobe Media Encoder. The problem is in my timeline the video is perfect as far as luminosity is concerned. Once I encode the video it seems to have a much higher contrast, to the point of being too much! It does not seem to matter what codec I use. Could someone tell me what I am missing / doing wrong? Thanks!!

How are you determining "the video is perfect" in the timeline? You do realize you can't use PP's built in monitors for this? You need a properly calibrated external monitor for correct and accurate color work.
And then I'd ask how are you judging the export? You do realize you can't watch it on a computer for this? You still need that properly calibrated TV for correct and accurate viewing of exports.
The problem is largely without that properly calibrated reference monitor, there are a lot of variables which interfere with accurate display of the media.

Sleep Display not staying asleep when encoding video

Hello,
I am looking for a way to turn the display off and KEEP it off with applications running as normal, until I want to wake it up. It is not always staying asleep.
I have a hot corner set up so that I can instantly turn my iMac display off (including the backlight). This works fine most of the time, but when running certain applications, activating sleep display works for a few seconds then stops working and the screen comes back to life.
Example applications which cause this are iTunes when encoding a video (e.g. converting a movie to iPod format), iSquint when encoding video, iDVD when encoding and burning a DVD - seems to be anything that makes heavy use of the processor.
I have tried all sorts of things to get around this:
1. setting the sleep display timer to 1 minute in the Energy Saving settings
2. 3rd party application and widget "Sleep Display" (http://linestreet.googlepages.com/home) which claims to make the display go to sleep and STAY asleep, suggesting "This version may work for people who experienced the monitor going off then coming right back on" - which indicates that it's not just me having the problem. This "Sleep Display" application doesn't work with Leopard though; the author acknowledges this and suggests he will update it if he upgrades to 10.5
3. different application - http://www.imalc.com/Site/SleepDisplay.html - this does the same as the hot corner and wakes up within a few seconds
4. sleep display tool in Dockables - same problem
5. "shades" system preference add-on, this makes the screen black and keeps it black but doesn't turn the backlight off
6. tried hiding the offending application, moving it to another space - nothing seems to work!
7. covering the imac with clothes - not ideal!
Thanks for your help!
Jim
P.S. the screensaver does stay on - so whatever is waking the sleep display isn't disturbing the screen saver - this suggests to me it's a bug. Obviously a black screensaver isn't the solution though - the backlight is still on.

I've got a very the similar problem. Brand new iMac 24" that shipped with Leopard -- my first Mac after jumping ship fom the Windoze side.
I had iTunes updating it's album artwork and since it was taking a while, I went to bed. When I turned out my light, I realized the screen had not yet gone to sleep (a good 15 minutes after it should have). So I set up a Hot Corner to put the display to sleep. When I put the mouse there, the monitor would go to sleep, but wake up within 10 seconds. At first I thought it was just the mouse moving as I walked away, but it wasn't.
I ended up turning the computer off because the big beautiful screen was throwing too much light. Since, I rarely turn my computers off and they're usually doing SOMETHING, this is really annoying.
Admittedly, I haven't tried some othe the potential solutions above, but this has to be the same bug. Screen saver stays on, monitor comes out of sleep.
Any help would be.....well.....helpful.

Encoded video doesn't work on Toshiba Blu-ray disc player

I have a problem that I am trying to encode a sequence of frames in a video container , but the encoded video doesn't work on toshiba blu ray disc player .. I am using the following ffmpeg command to encode frames and convert them to a video:
ffmpeg -i "C:\ManVsWigan\Frames\%d.png" -vcodec libx264 "C:\ManVsWigan\encoded.mp4"
I tried multiple video codecs but no luck yet
"-vcodec mpeg4"
"-vcodec mpeg2video"
If you have any idea please help me

The BluRay player leverages parts of Windows DirectShow but won't serve very well as a general player since Windows will load other players for the majority of media formats.
You can get away with a limited amount of tampering of the BluRay's players tolerance of media files until you violate some far away written DRM safeguard and kneecapping the BluRay player from doing anything.
If you're trying to validate your ffmpeg composed tests of your content as part of the editing process, you're better to avoid relying on the BluRay player that is purposed for narrow replay of licensed content and equipped with oversensitive safeguards susceptible to malfunctioning from the invasions of video pirates like you defined by studio executives.
You and I understand you're not a pirate but chances aren't being taken.
Whether you just dowloaded FFmep in the macho exe format or part of the millions of other packages that include it, you can tune your players to codecs pretty easily with the KLite Codec Manager or the Registry.
Chances are you already know about KLite since editing video on Windows eventually requires it and its hard to walk down the street without eventually kiceking over a copy. But just in case you've been living on a Martian cave with your hands over your ears, snag a mirrored copy from: http://codecguide.com /download_kl.htm
I like KLite more than others because it is fairly unobtrusive and avoids stomping over other media tools the way Adobe Premiere or Sony Vegas enslaves Windows and can neuter BluRay codecs without always adequately replacing them. I can cite threads on the matter but just googling for anything such as "Adobe Premier killed my BluRay" or "Sony Vegas ruined Windows" will usually return desperate strings of posts long enough to wrap around Jupiters equator.
For general maintenance of Windows poor codec management, grab this noninstalling executable http://www.nirsoft.net/utils/installed_codec.html to determine if Windows believes it has the same codecs you thought it did and you'll likely be surprised by the fine tuning you'll need to perform.

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

Encoding Video for DVD?

I want to make a DVD that will play in home players, though I do not need to make a menu using DVD SP. Is there a way to encode video straight from FCP into a file that will play in a DVD player?
Thanks.

This is really a question for the DVDSP forum, but the sum of it is that you use Compressor to encode your video to MPEG2 and your audio to 2 channel Dolby, then import those two files into DVDSP as Assets and drop them into the Timeline in DVDSP.
That will be Track 1, so select the disc in the Outline and in the Inspector, and you should find a drop down menu to make Track 1 the First Play. That's basically it, but I usually do one or two other things.
One: If this is for a trade show, or even a client approval disc, I'll set the Jump To for Track 1 to be Track 1. That will cause it to loop until the user stops it.
Two: I'll create a simple menu with a single PLAY button in the center, and map that button to play Track 1. That way, if the client inadvertently drops out of the play loop and wants to get back into it, s/he can do it by hitting Menu on the remote and pressing Select.
More details on all of this are contained in your Fine Manual.

Encode Video Files not working for avi files

Hi,
I've been trying to convert some .avi files to apple format using Lion's native 'Encode video files' function however keep getting a 'avconvert: source file not found for source file://fileparthhere avconvert: failed to create an export session. Check setup
I can't work out why as this has worked before in Lion and works fine for other video formats. The only thing I've done is remove Final Cut Express HD and can't add it again as I don't own it anymore
Suggestions? Is there a encoder to make this work or should it work anyway?
Thanks

If you click Yes the project file will be updated when you save it. That has nothing to do with the media.
Are the Lesson and Media folders still in the Book Files folder (or whatever it's called)?
Select one of the clips in the browser and use Edit>Item Properties. One of the first lines is Source. That gives you the file path for where your media is supposed to be located. What does it say? If nothing is there, use the File>Reconnect function and point the application to where the media is located.

Encoding video with JMF

Hi
i'm new in JMF and I'm trying to write a program that will encode video files to h.264 and also to divx. For know a made quite a lot of search and im still stuck. I tried with fobs but is has only decoding capabilities now im trying to do something with jffmpeg but it seems not to work for me (i mean encoding for decoding is ok) or i don't know how to make does anybody know what can i do ?? i mean some libraries that i can use or some tutorials.Is it possible to make something like this ??

The AVC or Advanced Video Codec / H.264 the MPEG-4 Standard is as smooth as glass. Very hardware intensive and time consuming depending on the size of your file. I reserve this for music videos and family video that I have captured to DVI. I am running a Windows machine dedicated to video work, P4 HT 3.6 overclocked to 4.1 and running liquid cooling and 4Gb of Ram.

Encoding videos to n82

how can i encode videos on n82 with full screen.i used nokia video manager and the videos to use the full screen.any good encoder??
At last a nseries phone im truely happy with THE N82

I have the same problem, been trying to make a disc image for over 6 months now, a wedding video of 2hours and 23 minutes long. It always seems to crash somewhere in the end part of encoding. Very frustrating. I had no problem if the movie is cut to under 2 hours but this particular project must be in 1 DVD in it's entirety. I am at the end of my wits and I cannot believe that iDVD with all it's upgrades cannot get it right. I also tried to export to full quality DV and remade all the chapters and to my surprise the audio was out of sync due to the original footage was in 12 bit audio. Back to square 1, upgraded my ram to 8 GB if that helps, reinstalled the whole OS with the upgrades, have 200 GB free space on the internal where the movie resides, have the latest iMovie 6 with the latest iDVD 6, repaired permissions, tried best performance and also best quality.. same end results..no disc image. The only way I can get this movie on 1 DVD is to export the movie sans chapters as is to a stand alone DVD recorder in VBR mode. Has anyone made a disc image of over 2 hours? Any suggestions appreciated.

Importing DivX 4.1.2 encoded video into iMovie HD 6

I had a PowerBook G4 1.67 GHz machine. With that, I could import DivX encoded video into iMovie HD 6. I had installed DivX for Mac 6.5 to allow this import.
I just switched to a new machine, MacBook Pro, Intel Core Duo 2.16 GHz.
I migrated over to this new machine using the Migration Assistant.
I just updated the system to 10.4.8 this morning.
When I import the same DivX encoded video into iMovie HD 6 now, the application crashes immediately.
Something did not get migrated properly...it seems.
Interestingly, there are a few video files that I had saved on my old machine using QT 7 Pro (still DivX encoded), and they import just fine on the new machine. I tried resaving the DivX video on the new machine in QT 7 Pro, but this does not rectify the problem. Very odd. I also now can not get QT Pro 7 to export these files as another encoded file. I could do that on the old machine.
I hope someone can provide me with the insight into the plug-in or reloading of something that will fix this problem. Is it compatibility of the DivX codec with the new Intel processor?
Thanks everyone.
MacBook Pro Mac OS X (10.4.7) Intel Core Duo 2.16 GHz

I'm working on a video at the moment and the way I'm dealing with it is with MPEG Streamclip. Hard drive cameras use a different format and you cannot import directly to iMovie. (Looking to go back to Mini DV Tape the way things are going)... Had to pay for MPEG Streamclip but it transcodes back to DV on the fly and then you spend hours importing to iMovie. I use a JVC Emperio hard drive Video camera. There is quite a deal of quality loss during all the various transitions unfortunately. You can also try... *Download and install DVDrop. This converts the .MOD MPEG-2 formatted video into standard Digital Video (DV) for iMovie. (see www.dropdv.com).* (cannot vouch for that one though. I'm going to try this evening. Thanks to Zac.

No option in contextual menu to encode video/audio in OSX Lion 10.7.1

Hey Apple Support,
As the title says, there is no option in my install of OS X Lion to encode video or audio by right clicking. I've included a screen shot to show you what I see when I try to convert, I've tried various formats like .mov, .avi, .mpg, .aiff, .wav etc
I upgraded from 10.6 on my late 2009 iMac.
Does anyone know how to fix?
Thanks.

Hi,
I have the same problem. I read some things to do with Automator but don't understand this.
Hope I will find a solution...
Sorry for my english.

[E71 on Linux] Best settings for encoding video?

Hello all,
I have an E71 and I would like to encode videos on my Linux box for it.
I have a script for that, using MPlayer's MEncode. I'd like to know what are the best settings, i.e.: Resolution, Video Bit rate, Audio Bit rate and Codec / file format.
Also, what is the best video player out there for the Symbian 9.1 3rd., preferably a freeware app...
I have DivX Mobile installed and the built-in Real Player (very poor quality playback - maybe because incorrect encoding?)
Thanks!

Does iMovie 11 use the GPU to accelerate encoding videos?

I noticed on imovie ’09, my GPU isn’t used at all to import or encode videos...
Does imovie 11 use the GPU to help out at all?

Some software use the computer’s GPU (addition to or in place of the CPU) in order to complete its given task in a shorter period of time. Photoshop is an example of one of these applications; it uses the GPU instead of the CPU to complete its tasks faster. 3DS Max is another example. It uses all available cores to render faster.
Now you might be thinking those all have to do with graphics... Well... Doesn’t imovie have to do with graphics, too? I mean utilizing the GPU to encode video is a good idea IMO. Even if you don’t associate iMovie with graphics, and somehow think it’s impossible for it to ever take advantage of a GPU, what about the other software that’s completely unrelated to graphics and video encoding? The legality or intentions of the software is questionable... (ie wireless network auditing) But regardless, it still takes advantage of the GPU to accelerate its tasks to incredible speeds. If stuff like that can do it, why can’t a program designed for processing video do it?
Anyway, I won’t be able to tell you if adobe makes NTSC discs or not. I already have toast 10 which I just discovered it burns NTSC DVD discs and even Blu Ray video discs without returning a demuxing error every other video. And to think it was only useful for burning data discs. It doesn’t use the GPU either, but it seems to encode DVD video considerably faster than iDVD.

Increasing Processor Usage when Encoding Video?

When I create videos in iDVD and it says that I am Encoding video in the progress bar, my processors are only about half used. I have 4 processors and 6 gigs of ram! Is there anything that I can do to have the encoding use the max my machine has? Could it be a hard drive issue? I don't think so though.
Kevin

Hi Kevin;
I don't think that moving the applications, iDVD and iPhoto, will do you any good at all. I would suggest if you have other disks available to try placing the source files of the video on one drive and the destination files for the encoding on another to see it that has any effect. It would probably be the quickest and easiest way to see if we are on the right track here.

Help Needed: Automator Applescript for Folder Action - Encode Video

Hi !
I have created an Automator Applescript for a Folder Action to do the following:
When a new video file is moved to the target folder (i.e. Download of Vuze is done), automatically launch the Applescript Action that does the followin g(Applescripted):
1) Using "run shell script" and FFMPEG on a UNIX command line, determine Width/Height, Framerate, Bitrate
2) Calculate encoding parameters (slightly reduced bitrate, reduced Aspect etc.)
3) Using "run shell script" with ffmpeg on the command line and the calculated parameters to encode the video file
At the same time, the action is written to a log file so I know if a file is recognized, when encoding started etc.
It works fine if I save this Action as an .app, make an alias on the Desktop and drop video files on it.
It also works fine if I attach the script to a folder as a folder action and drag a video file in there.
However, when I attach the script as a folder action to the Vuze download folder, it encodes only some video files, i.e. if there was a download of 5 files, chances are good that it will not encode 1 or 2 files out of those 5.
If for example a second download finishes while the encoding for the first download is still going on, sometimes the second file starts encoding after the first encode finishes, sometimes it does not, the file does not make the log file at all, i.e. the folder action missed it or the automator action dropped it because it was still encoding. Still, sometimes it happens, sometimes not.
As I need a solution that is 100% accurate, I would like to ask if there are any ideas on how to do this better maybe? As I am not an Applescript Guru, I would need some help to know what works and what doesn't and what the syntax is.
My main idea right now:
Similar to how ffmpegX works with its "process" application, have a second script (as .app) that receives the files to be encoded from the automator action and puts them in a queue, then proceeds to encode this queue while the main automator action is free to receive the next file.
Writing this second app is quite straightforward (a modified version of my current script) but I have some questions I need help with:
1) How do I call another applescript from within an existing applescript that launches the new applescript in a new process?
2) How do I pass parameters to this new applescript?
3) In case of this "Queueing" Idea, once I called the external applescript the first time, how do I make sure when I call next time, that I don't open a second instance of this script but rather pass another queue item to the original instance to be processed?
Or in general: Is there a better way to achieve this automatic encoding solution that I have not thought about?
Alternatively:
Does anyone know how to call the "process" application that comes with the ffmpegX package with the correct parameters to use as a queueing / processing tool?
Thanks!

To do this, I created an Automator workflow with an Applescript snippet to change the 'media kind'.
Here is the 'Run Applescript' workflow step code:
on run {input, parameters}
          tell application "iTunes"
                    set video kind of (item 1 of input) to movie
          end tell
          return input
end run
Prior to this running, I have an 'Import Files into iTunes' workflow step.
You can switch out 'movie' with: 'TV show', 'music video', or anything in ITLibMediaItemMediaKind.
Good luck,
Glenn
