Editing wt h.264 files

mac book pro 2.16 ghz intel core 2 duo, wt 4 gb and final cut pro 7.3 why cant i edit my raw h.264 files from my canon 5d mark 2 in final cut? i have seen it done on mac book pros twice befor wts wrong wt mine it studders when i edit. like i said i have seen it done wt out any conversion befor help

Because it IS NOT an editing codec. It might work some times, it won't work most of the time. VERY problematic codec. Not designed for editing....but rather for acquisition and delivery. You MUST convert to an editing codec, like ProRes.
I have a tutorial on how to deal with tapeless media in FCP...including Canon DSLR.

Edit .mts / H.264 file in premier pro and preserve time of recording (typical timedateoriginal meta)

There is a similar discusion in this thread, but I though i start a new focused thread, and sum up
Similar thread: http://forums.adobe.com/message/4212491#4212491
This is what i want to acheive:
My AVCHD camcorder generated a bunch of ,mts files.
I want to merge these into a single file, edit it in premier pro and generate a video in which the subtitle track contains the time of recording.
This is what i can do:
I can merge all .mts into a single .mts with the help of tsmux
I can then extract the timedateorginal meta codes of this file with all the recording dates and times with the help of subtitlemaker (url in my entry in the thread above) and make a subtile .txt file.
I can then add the subtitle track to the .mts file in Adobe Encore and i'm done!
But here is my problem:
I want to edit the clips. I can not do that in encore, i need premier pro for that.
However, if i start to edit .mts in premier pro, it seems i lose the meta data which contains time of recording.
Even if i go the really cumbersome way of editing each original .mts files individually (auch)..I still have the same problem.
HELP !
In my DV days life were easy:
Import the 9Gbps single DV file into premier pro.
edit the whole thing.
export as DV
run through http://paul.glagla.free.fr/fichiers/dvdate_71en.zip and generate a subtitle file which contains the time of recording dates and times for the video.
add subtitle to the video in encore, done.
I appriciate any solution. I don't think i am the only one with this problem. I have googled really hard to find a solution, but have had no luck.
Thanks...
Per

So..for anyone who has the same problem and find this thread, here are my 2pence.
I want to make a home move of our last 5 skiing vacations. I want a subtitle track containing the time of recording information.
I do not want a title overlay on the video, but when the discussion about 'when was that--!?' comes up, i want to be able to turn on subtitle. Simple !
I moved from DV to AVCHD (not because of HD Jim, but the DV camcorder was old, and newer seemed better at the time)
Hence my new problem: I have a bunch of .mts files, i need to edit those in a timeline editor, and get a subtitle track with the recording time.
recording time is in the -mts video meta data called timedateoriginal. To some extend also file attribute date of change (=time of writing to the SD card).
As it seems difficult to keep the meta data once you passed a timeline editor, and the file attribute does not make sense when you put a bunch of .mts files together, I think the best way forward is to find a timeline editor which also has subtitle tracks.
i.e. after steps 1) and 2) in my i have a single file and a .srt subtitle file to match.
I can now use those in a timeline editor.
Hunt is out for which editor, but it seems there are a couple of options. To be tested.
Once the sequence is edited, the new version of the subtitle needed to be exported so that it can be imported into adobe encore together with the final sequence for DVD/blu-ray authoring.
If anyone find a better way,, please let me know.
thanks...

Converting h.264 files for editing

When you convert h.264 files to edit, does it matter if you convert them to apple intermediate codec or prores? I'm going to export the finished project back to h.264 anyway so I just wanted to know if it made a difference, and what the advantages and disadvantages of converting the footage to either of those two codecs are. Thanks.

>Why won't the exported h.264 have the same settings as the original h.264?
Because the camera records H.264 with a bunch of settings that are specific to that camera. I guess that you can try to match those settings when you export...but to what end? Where will you show your work? How will it be displayed? YouTube/Vimeo doesn't play back video with that high of an H.264 data rate. Nor does DVD...BluRay has it's own spec.
The question is...what will you be exporting to for delivery...for final viewing? You'll be exporting a ProRes 422 as your master source...but then encoding from that the formats you need to deliver. Unless you plan on playing back in the camera, or via a laptop onto a projector...you won't be going back to that original spec.
>And if I converted the h.264 footage to prores for editing, and then exported it with prores, will that finished project be higher quality than the original h.264 footage?
Higher data rate...yes. But it will have gone through one layer of compression. But very good, low loss quality. Your eye really won't see the difference. But it will be better suited for editing and color correction...as H.264 is 8-bit 4:2:0 color space, and ProRes is 10-bit 4:2;2. It will be in better condition for editing and grading, but quality...about the same, ever ever EVER so slightly less quality. Nothing you'd notice.

How can I view and convert .264 files from my security cameras for use on my Mac and the web?

My security cams record in a .264 file format HD. I want to view, edit, etc on my Mac, what software will do that and are there any easy tips to do this? I'm new to Mac's so I'm not sure what is the best format to convert to? mp4? Suggestions?
Thanks in advance. I do love the Mac so far.

I have downloaded the trail....and it won't recognize my .264 files....not sure what the deal is? Here is a screen shot-they files are "grayed" out....and won't highlight. Do you see anything wrong? I'm pulling the files off of a Lorex DVR security system. LHD200

FCPX Project Render Settings - Can you edit in h.264 and Transcode/render only used clips on timeline to Prores during render?

I have a question on the PROJECT RENDER settings in FCP X. It’s seems to me that one could theoretically import and edit entirely with original h.264 video files without needing to Transcode to ProRes422. Once you’re done with your edit and want to get the added benefits of COLOR GRADING in ProRes422 color space, it seems that FCPX will automatically render your edit in ProRes422 according to these preferences. In that case, a color grade could be applied to the whole edit, and be automatically transcoded/rendered into ProRes 422 during the render process. After rendering, what would show up on the viewer and what would EXPORT would be the rendered Prores files and not the original h.264 files. This saves a lot of time and space of transcoding ALL your media, and in theory should enable you to edit NATIVE video formats like h.264, with automatic benefits of ProRes during render. I'm assuming the render may take longer because FCPX is having to convert h.264 video files to ProRes422 while rendering. This may be one drawback. But will you your color grade actually use the 4:2:0 color space of the h.264 native media, or will it utilize 4:2:2 color space, since the render files are set to render to ProRes422 ? Can anyone please confirm that this theory is correct and optimal for certain work flows?? Thanks!

Thanks Wild. That's what I thought - in that the render files would be converted to ProRes422 codec. So do you or anyone else think that there is an advantage to having the 4:2:0 original file be processed in a 4:2:2 color space?
Yes there is an advantage, any effects and grading will look better than in a 4:2:0 space.
Most professionals online seem to think so. Also - will rendering of heavy effects and color grading take longer using this method because it's having to convert h.264 media to ProRes during render?
Yes, it will definitely take longer.
Can anyone verify from a technical standpoint whether editing and color grading in this workflow will see the same benefits as having transcoded the h.264 media to ProRes in the first place?
Same benefits from a final product view point, you lose on rendering time though and if you have lots of effects things will seem slow as it will have render everytime from the h264 file rather than a Pro Res file for every change you make. This may be fine on a higher end mac but I'm sure just pummels an older lower end mac as to being almost useless.

Remove closed captions from H.264 file after converting?

I processed a video file in Compressor using the Blu-Ray settings, and included a reference to a closed captions file. I now need to use the file in another application (Adobe Encore), but the closed captions appear to be hard coded in.
Is that correct? Is there anyway to remove closed captions from a H.264 file after it has been converted with Compressor?
Please help This is for a film festival, and I may not have time to process the video in Compressor again without the closed captions.
Message was edited by: nicholas.he
Fixed question spelling from 'form' to 'from'.

From the user manual:
"QuickTime files: Compressor adds the closed caption file as a closed caption track to the QuickTime output file."
The closed caption "track" can be turned on and off. It is not burned into the screen, as is the CC standard. Encore should handle the file just fine. You should be able to tell the DVD to have Closed Captioning turned off by default. That's all it takes.
Sub-Titles may be burned in to the screen. If you did sub-titles, yes, you'll have to re-encoded from scratch without them. When doing sub-titles in an DVD authoring program, you have the ability to enable and disable them, but in Compressor, they're burned in.

Problems converting h.264 files for use in Premiere

Hello,
Given the fact that I've searched for an solution to this and everything I read is two steps ahead of me, I'm sure there is some basic no brainer thing that I'm overlooking and I apologize for being a noob. I'm attempting to edit HD files for the first time and the files come out of the camera in h.264. I first tried converting with mpeg streamclip but most of the codecs were apple. I tried a few codecs but none of them worked properly with premiere (video in source monitor was jerky, or it'd play fast and freeze on the last frame for the duration of the clip instead of playing the entire clip at proper speed, etc.).
I went through a few other programs and I've still had no success. Every conversion I attempt has some issue in Premiere. My new computer should have no issues running HD clips. It's an i7 quad core with 8 gb RAM.
I know I need to convert the h.264 files to edit in premiere, but I just need to know what program I can use to convert it and what codec will work in Premiere.

I'm going to guess that you're on a PC. Most folks editing Canon HDSLR on PC's seem to be transcoding to Cineform codec to get realtime editing. They have plenty of flavors at prices from $199-$1499 for the Prospect4K that is specifically built for Premiere. You can download 30-day fully functioning trial from www.cineform.com. You'll also find lots of helpful stuff over at www.cinema5d.com
CS5 promises native, realtime editing of multiple layers of h.264 files so I'll actually be putting my dough toward a new system rather than the cinefom plugin.

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

Working with 720p h.264 files

Is my Mac supposed to be able to work directly with 720p h.264 files? Macbook Pro 2,33 Ghz with 2 gig RAM...
From my limited testing, I have seen extremely slow scrubbing with the previously mentioned files.
I was thinking of buying a Elgato turbo.264 HD for importing video from my Canon HF11... but I don't think its worth it, if working with the video is so slow...
Any suggestions would be appreciated

h.264 is primarily a playback format. It is designed to be highly compressed, yet give high quality pictures. It is similar to AVCHD in this regard. AVCHD uses h.264 internally.
The way h.264 compression works is the [Group of Pictures compression technique|http://en.wikipedia.org/wiki/Groupofpictures], where for every full frame, there are, say, 24 frames of highly compressed information. For example, imagine a video of an eagle flying. You get one full frame of the eagle flying. The next 24 frames say, "background is the same, but shifted over to the left, eagle's wings are moving up and down, etc."
When you import AVCHD, iMovie converts all these partial frames to full frames in the Apple Intermediate Codec. You can do the same thing for h.264 by using a free tool like MPEG Streamclip. You can drag your h.264 file into streamclip and export as AIC full frames.
This makes it much easier to edit.

Converting H.264 files to Pro res 422

Hi
I've been given some H.264 files (.MOV and .THM) that were dragged onto my harddrive.
I want to covert them to Pro Res 422 to edit them in Final Cut
I tried to create a droplet to do this by: FILE - Create Droplets and selecting the Apple Pro Res 422 option in the Quicktime settings folder.
Is this correct? Or have I missed out a/some stage/s?
Do I need to convert both the .MOV and .THM files?
And how can I tell if the new clips are in the correct format?
Thanks.

If you import these files into Final cut just go to your sequence settings and transcode to APR.

A better workflow with h.264 files?

Hello!
Sorry for asking a total newbie question.
I am just starting to deal with video editing.
Ma camera is Sanyo Xacti.
My video is H.264, 1920X1080,
My first question is:
When working with Final Cut Pro where i had first to convert my footage to Apple Prores 422 codec to edit. It was fine but all this rendering business in FCP every time you want to try a new effect on a videofile or transition or something else really pisses me out. I come from the world of Professional Audio where the process is real-time and rather fast. Is the workflow in Premiere similar and after every operation you have to suffer from rendering? Can i preview the effects without rendering? These things are crucial to me, because with all this time-consuming rendering the creative fun goes away.
My second queston is:
From what i read about Premiere Pro CS5, i undestand that now i dont need to convert H.264 files and can work in this program without any additional conversion of these files. But i also read that this codec can be demanding on the computer. I use Mac Pro 8-core with 4 GB RAM. Will it be enough to edit my files in Premiere Pro CS5 as they are or it would be better to convert them first to some friendlier format (without quality loss, if possible)?
Thank you!

While I agree with Harm that things would go even more smoothly with more RAM, I'll add that you should be just fine with the H.264 footage from your XACTI. Premiere Pro handles AVCHD and H.264 quite well. If you set up your sequence right (the easiest way is just to drag the file icon and drop it onto the new sequence button), you will be able to playback without render. Once you start adding complicated effects, that may slow down playback a bit but you won't need to stop and re-render every few minutes. I moved to Premiere Pro from Final Cut Express for exactly the reason you describe and I've been very happy with it. I'm on a Macbook Pro with 8GB of Ram, but I just upgraded to 8 and when I had only 4GB I could still go through my footage and apply basic effects just fine without the need to render.

Can I import 264 files into Premiere Elements 11

I get a generic error when I attempt to import some 264 files. These were created on a cctv system.

As soon as I saw this post, I searched for the .264 extension in my hard drive. Found two files - could play both of them in Premiere Elements 11 and 12. Just imported them and played them on the expert room timeline.
Pathetic quality of the video though. I am not sure how these are there in my hard drive! Got to check with my friends for whom I have edited some projects if it belongs to them.

How to Edit a XML data file from AS3 class...

Hi...
             I need to edit an XML data file I have at the exit of application.... I have a demo code which is not working....
This is the code :
public function UpdateData():void
               trace("Closing....");
               var FileData:XML=<Hello>Hai</Hello>
               var urlLdr:URLLoader = new URLLoader();
               var urlRqst:URLRequest = new URLRequest ("AppData.xml");
               urlRqst.data=FileData;
                urlRqst.contentType = "text/xml";
               urlRqst.method = URLRequestMethod.POST;
               urlLdr.load(urlRqst);
This AppData file already exist and has some data in it.
    Plus :
   How to find the application is exiting.

use: fscommand('Quit');
to exit your app.
and this is how you would use the urlloader class to save data:
public function UpdateData():void
         trace("Closing....");
          var FileData:XML=<Hello>Hai</Hello>
var urlVar:URLVariables=new URLVariables();
urlVar.fileData=FileData;
            var urlLdr:URLLoader = new URLLoader();
           var urlRqst:URLRequest = new URLRequest ("this must be an executable to parse and write data");
           urlRqst.data=urlVar;
           urlRqst.contentType = "text/xml";
               urlRqst.method = URLRequestMethod.POST;
              urlLdr.load(urlRqst);
but i don't think you can use an executable on a fl4 device so you will need to use a different class. i don' know how you're storing an xml file on a fl4 device but you should be able to use the sharedobject to read and store xml.

How open and edit the coherence.xml file?

How can I open and edit the coherence.xml file?
I cannot find the coherence.xml file in the coherence.jar package.
Thank you,
June

If you are intent on changing the coherence.xml file, then you could use the JAR command (that comes with Java) to extract the coherence.xml file from coherence.jar and the later repackage the coherence.jar file using the udpated coherence.xml file, e.g.:
C:\java\opt\coherence-331\lib>jar -xvf coherence.jar tangosol-coherence.xmlextracted: tangosol-coherence.xml>
Instead of using JAR, on Windows you can associate the .JAR, .WAR and .EAR extensions with WinZip and use it to access / modify the contents of JAR files.
However, the suggested approach is as follows, and does not include any changes to the tangosol.jar file:
The tangosol-coherence-override-dev.xml file can be found in the coherence.jar file. After editing this file (in this case to define a unique value for the port system-property value for the multicast listener), save the file and add it to the server's classpath. When the server is executed, the values in the tangosol-coherence-override-dev.xml file will override any corresponding settings in the tangosol-coherence.xml file.Peace,
