Understanding Codecs

This is a common issue for me. My girlfriend asked if I could compress some videos into an email for her. I successfully demuxed a clip using MPEG streamline so I could get it into FCP. My intention then was to reduce the clip down in size and export it in a format that would sit nicely in an average sized email. This is where I hit a brick wall.
The reason is that I just don't understand the software or the jargon and attempts to find answers using the help menus are hopeless. I'll be starting work on a website soon and I know that without a fundamental understanding of codecs I'm going to be in the same sorry position.
I would have thought that somewhere there would be a list of the top ten requirements of the average person including those two - How do I compress a video for enclosure in an email that can be viewed by Mac and pc alike and how do I process a clip for streaming online? My foray into Compressor led to a prompt - Unable to connect to background process. Well I wasn't surprised, after all I can barely understand most of the options in any of the pull down menus.
So where can I find a simple breakdown of what formats and codecs mean, which codecs apply to which purpose. I get confronted with lists of picture and audio formats none of which say what media purpose they are for. I've tried the help menus on both Compressor and MPEG Streamline and the latter might as well be written in Chinese. There must be a resource that explains all this to the amateur user and doesn't require a one year course in media studies and IT.

Here are some simplified answers.
Container - often confused with format. AVI and QuickTime are containers but they are also files stored on a disk. They are often called and confused with being a file format. File format is really not the proper term for them, because the content is determined by the codec selected to create the video and audio that they hold.
AVI and QuickTime are containers. If you have the proper applications you can select among various codecs to encode your video and create an AVI or QuickTime file. AVI is primarily a Windows platform container; QuickTime MOV is more or less universal. Flash is a special case because it historically had its own proprietary codec and hence could have been thought of as a format; however the latest versions also support the MPEG4 and H.264 codecs so it may be proper to start calling Flash a container. Flash video has gained popularity because YouTube, GoogleVideo and other popular web providers use it.
Popular codecs for video on websites and email include MPEG4 (actually, MPEG4-Part2), H.264 and WMV. WMV is primarily a Windows platform codec. MPEG-4 is quite popular but H.264 has received a lot of attention in the past couple of years because it produces better quality video with smaller file sizes than the other codecs generally do.
Regardless of codec, there are other variables that affect the file size of your video, among them the on screen size (eg 640x480 vs 320x240, etc), frame rate, bit rate, compression quality, etc. Optimizing them is more art than science.
When you export from Final Cut, using QuickTime Compression for example, there are a myriad of settings you can tweak. Play around with some of the QuickTime Compression options, using H.264, and see what file size you get as a result. One note, however, viewers will need to have the free QuickTime 7 player to view H.264 videos.
I'd also recommend reading some of the articles on Ken Stone's website about producing video for websites, iPod, etc. It will give you some ideas of settings to use. For example, he's got a brand new article called Compressor H.264 movies from FCP for the Web ... should be interesting reading !

    My general problem is that when using Avaya VoIP client, my outgoing voice becomes garbled to the end user after a few minutes of conversation. My CPU, an Intel Pentium 4 (3GHz) also kicks into 50% utilization during a conversion, although when the conversations starts, it usually sits at about 7%. I have a high speed 5M download 52 K upload internet line. My sound card is an Audigy 2 ZS. I have eliminated obvious, like insuring other programs are not taking up CPU. I have 2 GB of high speed RAM also. I have also verified that the utilization is from the process in task manager for the IP phone client.
    I am wondering since the CPU is being hammered, if I am using a software codec for the VoIP communication link. My device manager shows 3 available audio codecs. I assume that a sound card has its own embedded digital signal processing capabilities that should be capable of doing audio compression. So, my question for any hardware sound blaster guru out there is: Does the sound card do G.729 or G.7 audio compression, or is audio compression for VoIP done by a software codec?
    Any comments regarding how audio codecs work in regards to VoIP will be appreciated.
    Thanks,

    If you properly graded your 8-bit footages, i.e. in 32-bit working space (in terms of PrPro that means enabling 'Maximum Bit Depth' in Sequence Settings), 10-bit render (for which you need to check 'Maximim Bit Depth' in the Export Settings dialog, unless you render into DNxHD in MOV container) preserves quality better than 8-bit. However, if rendering to 8-bit doesn't result in colour bending or something like that, common people will hardly see any difference.
    That's interesting. I've never checked that Max Bit Depth box in Sequence Settings. I don't do much grading. Color correction, yes, but nothing too crazy or with tons of layers. I figured checking that would slow things down and speed is paramount. On occasion, I'll noticed some color banding with my footage (like in the gradient of the sky) but not often and no one ever complains.  I used to check Max Bit Depth in export settings not knowing what I was doing but it sounded important so I did...but then I stopped when I had THIS>> (http://forums.adobe.com/message/4773556)<  issue with one of my exports (I changed many settings to get it resolved, and it only went away when max bit depth was unchecked (granted, now that you mention it, I didn't have max bit depth checked during editing in the sequence settings...hmmm).

  • Understanding codecs + video editing on slow machine

    Hi!
    I have really slow machine (Celeron 900). Editing Full HD, even with AVID DNxHD is a real pain. Export takes much time too. I decided to use offline mode trick discribed here - http://www.youtube.com/watch?v=6WK0sX75c4E (don't be scared with a cat in the begining ). And I started to play around with encoding options in Media Encoder to get best proxy videos. It's not simple and I can't decide what settings are right for me. Can you help me?
    And, in general, where can I find detailed info about different codecs, their options and usage? I really need someone to explain all this stuff.
    Hope on your advice!

    Have you looked into CineForm's NeoScene? http://cineform.com/products/neoscene
    When AVCHD was young, and many had less powerful machines, it was very good for them. I never used it, so cannot directly comment.
    Might be worth a look.

  • High quality export?

    Hi,
    I've been waiting for the GarageBand '11 update just to find out now that some instruments sound wildly different than what my iPad plays.
    I had hoped the GarageBand import of iPad project files would be my way to get a version above the quality the iPad exports for AAC, but apparently for my songs it's sounding so different that I hate what I hear (as opposed to what I hear from the iPad itself)
    Is there a good way to get high quality renderings of the single tracks out of GB for the iPad? I'm willing to record each track individually in real time, but what kind of connection would I use? Or is there a way to dig into the .band files created by the iPad and get prerendered tracks that the iPad creates when it "optimizes" the track?

  • What  codecs does Elements 7 understand?

    Does anyone know what codecs Elements 7 understands?
    I have both .avi and .mp4 files that I'd like to edit.
    I believe the avi files have been encoded via Xvid.
    Can I make Elements 7 work with these types of files?
    Thanks
    -Mike

    Michael,
    As Steve says, it is "best" to feed PE the files that it likes the best, DV-AVI.
    Now, PE *will* work with many files in other formats, provided that you have the proper CODEC's installed on your system. It's less about PE's working with CODEC's, and more about it working with file types. For instance, PE can Export to most CODEC's, that you have properly installed.
    Now, let's go back to "feed[ing] PE the files that it likes the best... " Since every AV file that you Import will be converted into DV-AVI for editing by PE, I find that it is better to do this conversion outside of PE. NLE's, like PE, really do not need to do extra work, and the conversion of AV files IS extra work. NLE's are designed to edit AV files, not convert them.
    I use a shareware converter, DigitalMedia Converter (Deskshare), and it works almost perfectly for me. It WILL use every properly installed CODEC on any of my systems. At last count, my workstation had about 450 and the laptop 340 installed (Audio & Video). It allows batch conversion, is quick and quite good. There are freeware, and other shareware converters available. I do not use any others for 99% of my work, as DigitalMedia Converter just handles it - including DivX and Xvid, with hardly a hiccup. For me, it's about the best US$40 that I've spent, right next to the "Pro" version of QT.
    In my workflow, I always start a Project by organizing and converting all of my Assets, so they work best with my NLE. If I had a bunch of non-DV-AVI files, I'd gather them into a folder, "Video," and make a folder, "Converted Video." While I was getting any stills ready in PS, I'd turn DigitalMedia Converter loose with the conversion of all Video Assets to DV-AVI with PCM/WAV 48KHz 16-bit stereo Audio. By the time my stills are re-sized and corrected for TV (assuming I'm in a DVD Project, like I normally am), my Video files are all converted and ready for Import. I do the same thing for all MP3 Audio Assets, as PCM/WAV (to spec above) is what works best.
    Now, I'm ready to Import and get to editing, which is what PE (or any NLE really) is all about. They use a good amount of a system's resources already, so I do not want them bogged down having to convert file types also. Besides, 3rd party converters usually do a much, much better job with the conversion - that is what THEY do best.
    It will save you a lot of grief if you incorporate ideas, like these, into your workflow, and do them outside of your NLE. Also, I find that it's also better to organize one's Assets into the Project's folder hierarchy, than to grab Assets from all over the system. It pays off, when you wish to "archive" the Project. It also means that I am not working with my original Assets, but copies that I have placed in the proper folders, within my Project's structure.
    Now, you do not have to do this. You can try and force your NLE to work with whatever you try to feed it. Your results *migh* be OK, but I'll bet that you encounter problems someplace, even if it's just sluggish performance.
    There are several recommendations for freeware and inexpensive shareware converters in the FAQ's section. Be sure to read all of those, not just the ones for your version of PE. If a program is recommended in the FAQ, it's because they work. I just happen to have some others, that I own, know and that work for me.
    Good luck,

  • CODEC Support - Red Giant Bullet-Proof Understanding Ingest-Export Sequence Choices?

    I shoot with a Canon EOS C100 that records AVCHD internally. I also use a Ninja Blade to record DNxHD at 220 Mps. I find no built-in support for either of these formats in Bullet Proof and Premiere Pro. Is there a reason for that?
    I'm trying to understand why the default export is MJPEG. For some reason, I thought that was an old codec no longer used. And it takes forever for Bullet Proof to export it. I have a very fast computer with an X99 2011 v3 chipset and 64 GB RAM, an Areca 12G RAID controller with a 16TB RAID 5 attached. And SSD for backup storage.
    I don't mind editing MJPEG. I just don't know if it is the best I could do, or if it's better to edit the original AVCHD. In other words, If I ingest AVCHD footage, is it best to transcode it to MJPEG or another format for editing? Since there is no preset for AVCHD, what then should my edit settings be?
    I also still do not understand the reasoning for the complex folder structure coming off the C100. I have read that it is important to leave that structure intact, but I don't see the benefit. Premiere has no use for it, it seems.

    with the constant changes to adobe's software, its helpful to know which version we are talking about. alot of people ask questions here with older versions of the software... 
    if premiere doesn't get your footage right when making a new sequence, then choose one that matches the footage the best by resolution and fps. you can also click on the settings tab, when making a new sequence, to customize it exactly to your needs. you can even save this as a preset that will show in the first tab with the default presets, so if you plan on using these media alot, you wont have to remake the custom sequence each time.
    im not exactly sure what all you do in bulletproof, so i hinted at prelude since it does let you transcode to alot more codecs. prelude is an ingest program, you can trim clips (but only if transcoding), add metadata & markers, and have it export to multiple locations as the original and/or in different formats. prelude will only show presets when transcoding, so if you need a different one you will have to open adobe media encoder and make a new preset in there. then it will show in prelude. i like red giants software, but bulletproof export codecs seem rather limited. if the pass-through option just copies and doesn't re-encode then that might work for you.
    when exporting from premiere you can also choose a preset close to your media and then customize it to your needs. you can even save it as a preset to recall later. i would stick with dnxhd for export, especially if you plan on bringing it back into premiere. dnxhd is very high quality if choosing its high bitrate format. there are several options for dnxhd 220, one should match your Ninja Blade. these are found under the quicktime format and video codec as avid dnxhd. its also available in mxf format.
    adobe's presets try to cover a wide range of cameras and media but can only cover so many, new ones coming out all the time... in sequence settings and export you have full control to customize it to your media and needs.

  • Understanding video formats/codecs

    what is a good reference for a beginner to understand video formats, compatibility, codecs, and the programs associated with converting these?
    I'm using Final Cut Express. I friend with a macbook has a video on it that was in a '.mpg' format. He also had the same video in two folders that were ripped from a DVD, they had to folders for Video_RM and Video_TS, I think.
    Anyways, I was hoping to pinch hit a quick video for him last night, rather simple 2-3 minute deal, where I use FCE to edit the video down. FCE didn't see the file as a movie. Neither did Quicktime 7 Pro.
    I rummaged around these forums enough late last night to find that handbrake and VLC might help. I finally was able to convert the file using handbrake to a readable format, mPv. iTunes enjoyed playing that version and QT7 Pro would play it also. FCE didn't play nice though. Still stuck.
    So I thought I'd be smart and let QT 7 pro convert the file to a .mov format while I slept. Right. 5 hours laters, my computer is still happily crunching away on the file and isn't quite 30% done if the progress bar is accurate.
    Any suggestions and reference materials is appreciated.

    Do not use Handbrake for this task. It is designed to convert DVD-Video into formats that play on other devices like iPods, iPhones, etc (converting one delivery format to other delivery formats).
    Use MPEG Streamclip or DVDxDV to convert the DVD's VOB file into an editable format that matches your FCE Sequence settings. Typically that would be QuickTime DV/DVCPro NTSC with audio being AIFF, 48 khz, 16 bit.
    what is a good reference for a beginner to understand video formats, compatibility, codecs, and the programs associated with converting these?
    The FCE manual or help file is a good place to start. Also check this: http://en.wikipedia.org/wiki/Video_codec
    For absolute basic information, understand that some codecs are for final delivery and some are meant for editing.

  • Can't make a workable custom codec with ProRes 422 (HQ)

    I've only just now found that there is a Support Community for Compressor.  Wish I'd known sooner.
    I see my version of Compressor is 3.5.3.
    I've been on a little saga.
    I started out with the challenge of converting some MP4 files from a Blackberry Playbook into ProRes 422 (HQ) for editing in Final Cut. I used Compressor and the task looked fairly straight forward. I used the ProRes setting in the Compressor, converted my files and imported them into Final Cut. Video was fine but I soon found out that the audio needed rendering every time I put a clip into the Timeline. I went on-line to various chat rooms with this problem. Pretty soon a fellow was telling me that the ProRes 422 (HQ) setting in Compressor had "Audio Pass-through" as default and that this was the cause of my problem. Change it, he said, to "Linear PCM".
    It took me a fair while to figure out that the ProRes setting in Compressor did not allow itself to be modified and that I'd have to create a custom preset if I was to make these changes. I set about to do that. I was able to select "QuickTime Movie" and then in "Video/Settings" choose "ProRes 422 (HQ)", in "Audio", "Linear PCM". This did solve the audio problem. Now files imported into Final Cut did not need rendering. But another problem became evident.
    Whereas the ProRes 422 setting that came with Compressor in its summary page listed: "Width" and "Height" as "(100% of source)", the custom ProRes 422 (HQ) setting I'd just created has "Width" and "Height" as "320" and "240". In short the 19:9 aspect ratio of the original footage was lost. What I got both in the conversion and in Final Cut was a squished SD image.
    I've played like heck with Compressor trying to see if there was some place I could get this custom version of ProRes to correspond to the aspect ratio seen in the Audio Pass-through version that came loaded in Compressor. No luck. All very mysterious.
    My next step was to look to create another custom codec that would have the proper 1280 X 720 ratio. Turns out  "HDV 720p 30fps" does, so now I've been converting to that. Looks fine in Final Cut - proper picture and sound.
    I've been playing around a bit more and see now that I can create a custom setting using "Apple Intermediate Codec". I've tried it and it works too.
    So after all this, my question: Should I be using that codec instead? Or does it really matter what codec I use for editing? Is the only real issue what codec I decide to use to output?
    And while I'm at it: Does anybody have ideas why trying to create a custom setting with ProRes 422 (HQ) does not work - for my purposes at least.
    I must admit this converting codecs is pretty new to me. Hopefully with time this experience will get easier and clearer.
    John

    Setting a Compressor ProRes Custom Setting:
    1) Pick Apple ProRes 422...
    2) Drag the PreRes 422 setting to the Bach Window. You can only make a custom setting from the Batch Window...
    3) Select enable for the audio. Click on setting to make sure it is set right. Uncheck Allow Job Segmenting... Make sure Streaming is set to none*....
    4) Select the Geomenty tab... Pick Custom (16:9):
    5) Click Save As and name your custom setting...
    6) You new custom setting will show up in the Custum folder for later use:
    Another thing you can do is make Droplet of this custom setting. Menu... File... Create Droplet... Save the Droplet into a folder somewhere on your computer.
    A Droplet will start the transcoding automatically. Drag the Droplet onto a video icon and let it do it's job.
    * ProRes doesn't need the Fast Start setting. If this is set it will take almost twice as long to do the encoding. Same with Allow Job Segmenting using Qmaster.
    I did the above on the fly and hope everything is clear for you to understand.

    Help!
    Thanks, Mark

    Unfortunately, the error message gives no details about what codec might be missing or what it needs.
    If the file can't be opened in QT, it only means you cannot use the QT "Inspector" window to check what compression formats were used to create the file. It does not mean you can't use the Finder "Information" window to check on the compression formats or use a third party media information window (e.g., like VLC which will open many compression formats not supported natively by QT) to determine what kind of data is included in the MOV wrapper. If the file cannot be opened in any app, it is usually a good sign that the file itself is corrupted.
    It's a stupid error message. Apple should do better than that.
    Error trapping is quite extensive but there are still many areas which require human oversight. The message is telling you that either the container has a problem (e.g., not properly terminated, non-standard, or corrupted) or that one or more of the compression formats used is not supported by your current codec component configuration or that the data was encoded using non-standard settings or preferences not supported by QT or that the fourCC code does not match the data contained in the file or that there are timecode inconsistencies, etc., etc., etc. In short there are a near infinite number of possible problems for which it would be very difficult/nearly impossible to program error trapping depending on your sourcing of content and how you process it before it reaches the player app. Think of it like trying to play a BD disc in an DVD player.
    I'll call Apple support when I get a chance.
    Chances are good that they will end up sending you back here. In any case, it is often a good idea to post a sample file for examination by other QT users. At the very least, they should be able to tell you if the sample file will play on other systems which would indicate whether or not the file itself is bad and under the best of circumstances whould allow them to examing the file in detail for various common problems.

  • Canon 60D saved footage files in H264...need to convert...is there a way to automatically shoot and save as a different codec?

    Hey,
    My friend has the Canon 60D. We shot some footage and I uploaded it to my computer and saw that it was H264 codec. I now have to convert it all to ProRez Lite. I'm not too familiar with the camera but - is there a way for the Canon 60D to automatically save the files it shoots to a better codec so that when I upload them to my computer it's ready to go?
    My friend only has an 8GB SD card. The stuff we would be shooting would'nt be too too much footage but if there was a way to make it save as something like Pro Rez lite where it can be editable in FC and still a decent file size that would be great.
    Thanks

    Thanks for the replys. Since it's not my camera he was just letting me borrow his sd card, so I wouldn't be able to do the log and transfer thing because I won't have the camera/usb etc. But that seems like the transcoding would take some time regardless since it's still converting.
    I usually use the regular Prores 422, but I mentioned trying out pro res lite cause I hear the quality is similiar and less on the file size.
    I guess I will have to just deal with waiting to convert footage everytime I want to edit. It doesn't make sense to me why their default is a delivery format on a prosumer product... I can understand iphones being h264 cause they need it small compression on just planning to upload it raw to youtube or something but with a dslr which would most likely be used with editing is in a delivery codec... So is that the standard workflow with everyone to spend hours converting first?
    Thanks

    Opened a new sequence and imported the old one (this allows me to work with the file once, but if i try to open the new sequence it gives me the same message)
    Whats really messed up is that another machine in the office has been able to open it. We are on the same versions
    And please excuse this last part, its a bit of venting my frustrations.
    Why is there no troubleshooting hotline? I went through the support page a couple of times before realizing it was just looping back to itself and offering no solution other than reading the forums. The instant messaging and support phone line are only for installing and purchasing products. I understand that filtering everyone to the forums is a convenient way to save time and money but i'm now out of resources to read and have gotten no where with no idea of how to proceed. pages like https://forums.adobe.com/message/4626663#4626663#4626663 offer no help because they don't actually address the issue of missing codecs, only how to sign out of Creative Cloud Desktop.

    Hi Aaron,
    The issue that you are facing is related to activation.
    Please go to the system library on the computer-application support-Adobe and rename the SLStore and SLCache folder.
    Relaunch Premiere Pro and check if it works or not.
    In case this doesn't fix the issue, then go to the desktop screen, click GO on the top-Go to folder, type /etc
    Then find the hosts file and see if there are any Adobe Entries, Please remove those entries and save the Hosts File.
    Thank You
    Arjun

  • Help me choose a 'Single Codec' for conversion?

    I am preparing my footage to edit a documentary which I shot using three cameras:
    DVCPRO HD (1080/25p) Panasonic 171
    H264 (1080/25p) Canon 5D Mk II
    AVCHD (1080/50p) Panasonic TM700
    My confusion is concerned with the DVCPRO HD stuff being 1440x1080 whereas the 5D and TM700 are 1920x1080
    I want to convert all the formats to a single codec.
    My question: - Should I convert everything to ProRes, or convert the 5D and TM700 footage to DVCPRO HD? I'm trying to understand if there are any 'disadvantages' to converting DVCPROHD to ProResas both are iFrame.... but am concerned about scaling.
    Many thanks

    Thanks Jim, i'm moving towards that viewpoint myself.
    As a supplementary question, i'm curious if transcoding from DVCPRO HD to ProRes 422 will affect the image quality in some way .... I've tried this and they look the same to my eye, though going from one compressed file type to another suggests a loss in fidelity?
    Thanks, Johnny
