  • Burn (.mp4) iMovie to disc w/iDVD?

    Created a movie w/iMovie - is 28 + min long - "exported 'Théâtre'" & created a file on hard drive... exported as a .mp4 file in "events movies/iMovie / * .mp4", however when I open iDVD (7.1.2) and try to create a new project, or Magic DVD... whatever... the .mp4 file appears not anywhere in my options. Can I just move it (drag & drop)? IDVD does support the .mp4 files? I'm so confused by this...  The file is "too long" (more than 15 minutes) to be supported in iCloud, so it will not appear in iDVD... is that correct? Why do not these programs get along perfectly...?

    DVDs are standard definition so your HD file cannot be used.

    Share file into iMovie and change the size of the 480 size and save it to your desktop. Use this file with iDVD.

    MPEG-4 (.mp4)

    MPEG-4 is a specification of the international standards organization (ISO) that covers many aspects of multimedia presentation, including compression, creation and delivery. Although the video compression and file container definition are two entities separate and independent of the MPEG-4 specification, many people mistakenly believe that the two are interchangeable. You can implement only the parts of the MPEG-4 specification and stay compliant.

    The file format MPEG-4, as defined by the MPEG-4 specification, contains encoded MPEG-4 video and audio content encoded AAC Advanced Audio Coding. He usually uses the .mp4 extension. Windows Media Player does not support playback of the .mp4 file format. You can reproduce .mp4 media files in Windows Media Player when you install the decoders compatible DirectShow MPEG-4 packs. MPEG-4 compatible DirectShow decoders packs include the Ligos LSX-MPEG Player and the EnvivioTV player.

    Audio for Windows (.wav)

    Versions of Windows Media Player that support this file type:

    Windows Media Player 7

    Windows Windows XP Media Player

    Windows Media Player 9 Series

    Windows Media Player 10

    Windows Media Player 11

    Windows uses the file Wave Form Audio (WAV) format to store sounds as waveforms. One minute of its coded in PCM Pulse Code Modulation can occupy as little as 644 kilobytes (KB) or 27 megabytes (MB) of storage. This size of the storage space depends on the sampling frequency, the type of sound (mono or stereo), and the number of bits used for the sample.

    Similar in format AVI, ASF, WAV is a container file only. Audio content that is compressed with a wide variety of codecs and that is stored in a .wav file can be played in Windows Media Player if the appropriate codecs are installed on the computer. The most common audio codecs that are used in .wav files include Microsoft Adaptive Differential Pulse Code Modulation (MS ADPCM) and uncompressed Pulse Code Modulation (PCM).

    I also suggest you to perform a search engine of search favorite you hot to convert a .mp4 file to a .wav file.

  • Windows Live Movie Maker - video editing MP4

    I recently returned from a trip with some MP4 videos taken on my new GoPro Hero2. When I play videos in Windows Media Player they are sharp and crisp. However, when I load into Windows Live Movie Maker, they lose their resolution and become much less clear-cut. My intention was to W Live Movie Maker allows to cut videos and also (for some videos) to take snapshots of some of the images in the videos.

    Can someone tell me if there a way to avoid the loss of resolution?

    t; Preview he in Movie Maker shows you a lower quality project of the record... When you save the movie to a HD definition should be comparable to the file of the GoPro Hero 2.

    I have the same model of GoPro and fine work of editing/backup using Movie Maker for a high quality video...
  • Captivate MP4 8 and buttons

    Hello

    2 questions 1. One button works if I publish a MP4? 2 - is the setting "Open URL or file" when coming out of the last slide not working when and MP4 is created?  I'm doing a simple gesture to open a URL to a video that isn't a HTML5. I tried all the options I can think of and nothing seems to be getting the URL to open, or the same key seems to be active when you publish a MP4.

    Thank you

    No, the MP4 is a video format which means by definition non-interactive.

    Hi dagleich,

    Thanks for the information. The problem can be located on the format of your videos. I checked the model number and found out that your camera records in MiniDV. Unfortunately, video tapes and CD recording is not transferable on DVD using the House PlayMemories disks. Even with their conversion into files Mp4 Mp4s cannot be burned on DVD discs.

    I would recommend looking for a local camera shop that could help to convert your files and save them in another medium.

    To get help with your concern, we recommend that you visit our Sony Global Web site for more information on contacting Sony's Support Center in your area athttp://www.sony.net/SonyInfo/Support/.

  • First issue 14 - items exporting in MP4

    I'm running a pc Windows 10 (spec below) and have problems to export projects like MP4.

    I initially downloaded trial version of first 14 elements, created a second 6 video and successfully exported a MP4 (the piece of MP3 music, I had included did not play, but I think it's a limitation of the trial version).

    After this success, I bought the complete product and tried to re-create the MP4, it failed with the first error 'Adobe Premiere Elements has stopped working' and error 1000 has been created in the application log:

    Name of the failing application: Adobe first Elements.exe, version: 14.0.0.0, time stamp: 0x55e5a5ad

    ID of the failed package-parent application:

    I retried several times without success, normally with the same error (at various times in the export process - sometimes it takes 90% full) or, Alternatively, the whole PC to hang or restart (I also tried to make minor modifications and re-register with the full version more remove all rendered files).

    I then tried to create a new project with a different video content and who do not have to export.

    I tried from my pc with minimal services (System Services more than the services of Adobe) and no project would export MP4.  I then started without System Services and the new project has actually exported successfully but not one created in the trial version (I think it was a "fluke" however).  I also tried to export with no other applications running.

    To create the MP4 I finally break the project down into 8 short projects, export them as MP4, create a new project, adding them back in and adding music.  Who then exported successfully a MP4.

    I use the recommended MP4 export definition 1280 x 720, but have you tried lower resolutions too.

    I have also tried exporting as a MT2 (HD1080), this succeeded and I'll then return to first export an MP4 with success.

    I don't think that my video is complex: it is market day, created on a GoPro Hero 3 in MP4 format.  There are about 1 hrs shooting in several clips and I extracted about 20 clips to create the 6 minute film.  There are transitions between each clip.  I used some video stabilization, but not on each clip.  There is an MP3 to add music.

    I looked at the performance of the PC while exporting (via Task Manager) and PE used about 80-90% CPU and 30% of memory.  I checked that the drivers and devices/system apparently are aware.

    I have 7 of QuickTime for Windows 10 installed.

    I tried to uninstall PE 14 (including preferences) completely and reinstalling without effect.

  • Part of my video is missing when I export to mp4

    I know my way around photoshop illustrator indesign etc but I'm kind new to the after-effects. Im working on a project and have been sent a video mp4 to work on. I imported the video on my project, so I can add text etc. Everything is fine and I like when I'm working on it, but as soon as I have the export queue the Media Encoder, I support on export and I can see it in the window of loading but then all of a sudden the video that I imported disappears, but the text is still there? I returned a checked the length of the clip and made sure his in the right position and everything seems as it should. I don't understand why when I play the video in after effect its fine all but just when I export its losing half of the imported clip but everything else is still there so it is not only the fact that the entire video is the short cut. I know that this is not the best description of a problem because I'm not very good with the technical terms, but if anyone can help it would be much apprechiated

    Based on the information at hand, here's a band-aid.  Maybe:

    Open the computer.  In the timeline panel, press the home key, then press the 'b '.  Press the end key, then press the "n".  You have just reset the AE area to the length of the model.  Now try rendering again.

    And because EI is more sensitive than other applications of discrepancies in the version number, version of the os, hardware, memory, etc.  It definitely helps to watch it:

    FAQ: Should what information I provide when you ask a question on this forum?

    And because the AE does not work like other apps and is by no means not intuitively usable with no success, it is specific help:

    Getting started with After Effects (CS4, CS5, CS5.5, CS6, & CC)

    Learn the underlying principles using AE and learn how AE 'think' will help a lot.

  • creation of definition video standard bluray

    Hello everyone. I downloaded adobe first 13 items and have read parts of the manual that apply to my question. The manual suggests that the bluray standard definition video can be created using the mpeg-2 codec. However, I tried but was unable to do: I only saw options for high definition bluray video! Therefore, can someone explain briefly how this is done. I would also like to know whether or not H 264 codec can be used to create standard-definition bluray video and if so, what flow values are provided for this task. Finally, I would like to know which audio codecs can be used in creating video definition standard bluray?

    Replying to your message 13...

    Thank you for your response and look at considerations that I brought to your attention.

    The results I posted in post 10 for my MPEG2.mpg PAL (16:9) are the same for sample 4:3 AVCHD.mp4 (640 x 480 @ 15 fps progressive) you have decided to send. (Please refer to my post 10.)

    End product screen Blu - ray's 1920 x 1080 16:9, any use of the 4:3 source (such what) will cause black borders on the final product disc screen if the burn is successful.

    And, we are already at a mutual agreement that 720/480 or 640/480 resolution must not be obtained a first Elements 13 burn to Blu - ray disc any amount is or is not on the timeline.

    Thank you for considering observations.

  • The concept of placing a MP4 file to 16 GB on a 4.7 GB DVD

    Hello, when I use ss12 to publish my images from video cam MP4 16 GB on a 4.7 GB DVD I'm losing a large part of the original video quality? Looks like I have to be.

    Creating a DVD does 2 things in your file

    1 reduced the size of the HiDef screen to Standard definition to meet the specification of the DVD

    2 compresses files by SUBSTANTIALLY reducing the amount of data

  • Comverting camcorder HD MTS to MP4 with PE11?

    Hi people,

    I just got a Canon Vixia HF R300 and record its highest definition. According to its manual, this type of "MXP" is 1920 x 1080 @ 60 fps interlaced.

    But to my great regret, the camcorder came with almost zero software. Just a "Transfer Utility" Pixela who little more than copy the Multilateral trading system of the SDxc card on my hard drive, something that I can do it manually. In addition, the film is divided into segments of 2 GB which averaged very close to 11 minutes and 27 seconds of film (and an hour is about 10 GB).

    When I pull this in PE11, it indicates that the properties are MPEG Movie, 1920 x 1080, 29.97 FPS, pixels 1.0 format.

    I want to keep my home movies with the best possible resolution (which I can only imagine is the original resolution), but it's nice save space if possible

    I'm an amateur at this and want to make sure I'm not missing something...

    If I output 1920 x 1080 @ 29.97 MP4, will be I affect it all? I noticed that the fps is not the same, but interlaced is kinda sorta half speed, anyway...

    And I assume that it's ok to concatenate parts of 2 GB.

    In addition, I ruin anything by copying directly ALL the MTS files? I see that makes a few small tracking files whenever I have video. All seems ok in PE11, but maybe I don't realize miss me something.

    Help or comments appreciated! Cannon left a little high and dry users... but then, I had a pretty decent piece of cheap hardware. So, you get what you pay for.

    Thank you!

    So, how do you intend to 'archive' your family memories? On BluRay discs? On a hard drive so that your family will need to gather around the computer, whenever they want to watch your old movies?

    The way you want to see your films determines the best model for outputtting them.

    If you use Premiere Elements to copy your files to your video camera depends on the results you get. If you are using Windows Explorer works, so go ahead and use it. If this isn't the case, then you should use importer Premiere Elements' video, as I explained in my tutorials at Muvipix and in my book.

  • Share a movie in high definition video Flash

    Hello:

    I use Premiere Elements 4.0, and I would like to create a Flash video in 720 p from a 720 p input file.

    Use the presets, I can create a MPG 720 p without problem, but there seems not to be greater than 640 X 480 setting of Flash Video.  Is there a way to create a FLV to HD format so that it will be displayed as HD on You Tube?

    Thank you

    Rich Locus

    The best solution we found is the video as a MP4 high-definition output and YouTube re - encoding in FLV format, by the frequently asked questions to the right of this forum.

    http://forums.Adobe.com/thread/623549?TSTART=0

    You're not going to get any higher quality ranging from FLV to FLV, because the program still him convert to its workflow in any case format (AVI or MPEG and HDV) while working with her. Additionally, the biggest quality problems appear when YouTube starts to screw with it, that there is no way around.

    Give him a H.264 file, and you will get the best possible results.

  • PE4 crashes when working with videos MP4

    Hello everyone - just got a new Samsung HMX20 camera - shoot in full HD and creates clips in MP4 format.  I did some tests on cam before shooting to about 111 clips today, for a total of about 30 minutes of video.

    The test worked great, looked CLEAR and fabulous.

    I started PE4 and captured all the clips very well.

    However, when I try to import more than about 10 clips in a new project of PE4, he takes (no warning or message) and goes to a blue screen, then restart my computer.

    System Specs: 1 month, HP Pavilion DV7, AMD Turion Dual Core 2.10 GHz 4.0 GB, 64-bit system, 184 GB free of 284.

    I have a backup drive I could use if necessary, but do not know if this can help - I thought it would be better to have everything on the C drive...  Although it is perhaps naïve of me.

    Any thoughts?  It is a client project, so any help would be GREATLY appreciated!  If you have any questions to help your understanding of the issue, feel free to ask.

    I used successfully the PE4 with my old Panasonic cam (not HD), and this question has never been so far, when you try to work with many clips.

    I'll also post this to movipix.

    Thank you!!

    It's probably MP4 video format that gives you the questions, it is a variant of H.264 (MPEG-4. STROKE) that is similar but not identical to AVCHD. Infact I'm surprised that you can work with clips in PE4. Full HD AVCHD support was introduced in PE7... PE4 supports HDV MPEG2 format. Infact Adobe had to do some work to "optimize" the memory management to get the AVCHD to work.

    What project preset are you using? And you plan to export high definition or standard definition? Your best bet would be to convert to DV - AVI clips, if you plan to export SD or HDV MPEG2 if you plan to export as HD.

  • No sound/audio in MP4 files

    Hi hoping someone here can help out - I use El Capitan 10.11.6 and the audio is missing some MP4 files that I downloaded from a GoPro camera. My sound is fine otherwise, output noise is fine, alert sounds are fine. MOV files off other cameras play well with audio easily here, but I don't hear anything in the files MP4 Quicktime, VLC, Final Cut Pro X, even if in Final Cut Pro X there is an audio waveform on each clip and they were converted to Quicktime using the MPEG stream clip (there no audible sound in the program either). I tried the same files on colleagues Mac running Mavericks and the sound is fine out there so here something to replace or reinstall?

    You run the same exact file on El Capitan and the Mavericks?  Shouldn't be any change unless MPEGstreamclip has been defined to use some esoteric audio codec in the file.  First of all, there is no reason to convert the files off your GoPro.  FCPX will work with native files very well.

    And, if you never convert, use the GoPro Studio app for this.  Nothing I do will have problems with the standard files.

    We use GoPros all the time and didn't have any problems.  What are the settings on the GoPro cameras?
