• Markers and audio synchronization

  I would like to be able to synchronize events to match a narration. I imported the audio file into the library and it loaded on a layer, but it does not seem possible to scrub the audio or start then stop the playback head to place a precise marker. Do I need to do it in an audio editor and manually add cue points?

  Select the image that begins your sound. Go to the Properties tab and find the settings to 'Sync '. Change the first drop 'Stream' and you will be able to rub your sound.

• Video quality has dropped and Audio Out of sync (EPA 12)

  Edited a video of 30 minutes and took a few clips of him. After the project and saving it, I noticed a severe drop in video quality and despite to realign the tracks audio/video, audio installs always out of sync. Original video clip plays fine and I would just download those, but there are too many dead zones and some splicing that needs to be addressed. At first I cut sections of video caused the problem, but the video before editing it produced out of sync titles as well. on a 30 minute video, audio Animes before nearly 10 seconds.

  I was see several other discussions on this topic with different answers, which makes me think that every problem is something different. Also, there are not too many threads with solutions. Also concerned by the fact that this problem seems to go as far as 10 EPA.

  I see no mention of rate constant or variable in the documents of the camera (only 30/60 NTSC or PAL 25/50).

  The only clue that I don't have that cadence is variable, it is as 29.412 frames per second that you give to your video.

  I had advanced for the camera users section and can't find anything that goes with this question. If your camera records with a constant speed then you will see 29.97 or 30 and not 29.412.

  We support the idea of constant compared to variable rate for your video by running the video via the properties of MediaInfo program playback. If your video has a variable rate, reading on will give a minimum, 'general' and maximum playback for cadence.

  Just be careful for carryons unwanted in the download of this program.

  You seem to have 1280 x 720 @ 29,412 progressive frames per second (variable frequency), presenting as AVCHD.mov. And apparently you transfer the recording to the camera as the video compression AVCHD (MPEG4 AVC/H.264).mov, not a "MPEG" such as MPEG2 video compression...

I have the iPod video and iPhone 5 (with variable rate) and any import problems (audio out of sync or other), edition, exported from Premiere Elements set the correct project presets and work with content timeline made.

• Making the best use of space for the quality by balancing the video bitrate and audio settings?

  I have a few questions about the first export still / encoding in encore. I am trying to create a dvd single layer, where I maximize overall quality using as much space as possible.  The video is 97 minutes, SD 720 x 480, 29.97 FPS and consists of interviews for the most part, as well as b-roll hd cameras and stills, rare title graphic card.

  1. I can use dynamic link to send the sequence that appears to maximize the space available, however I have heard that using DL is generally frowned upon and I myself cannot tell what settings it uses (for example vbr, 2 pass, etc.). Is my interpretation that DL is not the ideal way to go wrong? If DL is just as good as a separate output, is there a way to know what parameters it uses?

  2. I used a bitrate calculator and tried a Min: 3.5 target: 5.5 Max: 8 audio output PCM and I found myself having a little more than 400 MB of unused space. When someone recommended a Min: 5.5 target: 7 output Max 8.5 the file size is too large with a simple DVD layer. I read that it is recommended to use an exit instead of PCM, if the video is over an hour audio Dolby. My question is is it a best practice to balance needs of flow rates and audio and video? I realize, of course, by using more data PCM is 'better', but it is usually best to go on the road to dolby and have more space to increase your video bitrate? What is the audio difference type that requires a high-end system to discern? Y audio data loss is worth for the benefit of video bitrate higher?

  I know it's a lot, just trying to maximize space to get the best possible performance. Thanks for any help/advice you can provide.

  -Nick

  As most of my videos are closer to 2 hours usually, I always used Dolby Digital, PCM takes so much space and I prefer to use this space to increase video quality.

  Note that by default, if you import a .wav (PCM) file into Encore, it transcode automatically that Dolby, unless you have changed specifically the default settings of transcoding in Encore.

  A decent basis for coding rule is 560/minute = bitrate, so 560/97 = 5.77 and I usually just round off a little for menu overhead and margin of safety. This requires using Dolby to 192 k, so I would use 5.6 average bitrate.

• Audio film blackBerry Smartphones BlackBerry Torch and lag synchronization problems

  Anyone has this problem where after some time watching a movie the audio appears trolling out and synchronization of his lips is the way out. The image also appears to stutter and lag? Any who have the same problem and or know to remedy this? The files work fine on my mac, but when on the Blackberry, they have this problem. Its quite annoying, so anyone with a fix or a solution that had the same issues please let me know how I can sort. Thank you very much

  Hi RADIKAL69

  If you watch a movie, I would recommend ensuring that no other application works (apart from the basic such as Messages, home, telephone, BBM and browser apps).  You can do this by pressing the menu button to see what applications are running and enter each of them to close in now the back button, or by pressing Menu > close/exit.  In addition, for best performance, disable all network connections.

  If the BlackBerry is your film treatment and trying to deal with other tasks in the background, this could cause some lag in the audio synchronization.

  Thank you

• audio and video synchronization does not

  I recorded a video clip of an audio interview separated, and I've marked the beginning of the clip with a Clap and spoke the take number and content to make life easier, as I usually do. The craft is borrowed at school, and for some reason any audio that came out the Canon 5Dmkiii was really weak. This could be the reason why, when I set the video and audio in their own sandbox and right click and merge clips, (with the point under the audio tab by checking the box to delete the audio clip AV and as audio synchronization) that the clip does not seem to recognize the breaking of the Clap or something perhaps? Is it possible that I can fix this or should I it synchronize manually? If so, is there a quick and easy tutorial on youtube or something that is recommended?

  I discovered that if I put markers manually on the point where the Clap snaps and select marker instead of the audio as the point of synchronization, then it synchronizes to the top clips properly.

  Not sure if your video was recorded with a variable rate without more information.

  1. what operating system for your components 14/14.1 first?

  2. what camera or device recorded video? If a mobile phone, iPad, iPhone, or one of these screen capture programs, it is most likely that you have a variable rate for your video. Premiere Elements has problem with this type of video. The symptoms of this beach of situation of desynchronization of audio to not be able to import the video at all. The typical solution into your video HandBrake for the H.264.mp4 with the version of constant frame rate and put in Premiere Elements project.

  3. you have two approaches to this issue of variable frame rate...

  a. before you think about hand brake, hold the program playback of video and audio of MediaInfo properties to determine if your video has 3 instead of 1 frame rate in video on the video display. If 3, then go ahead with the variable of Handbrake at the session of rate constant frame

  or

  b. do not bother with MediaInfo reading, just take the video into a brake hand, get your H.264.mp4 with constant cadence. If it works, OK - happy with the solution and assuming that this variable image has been the cause of the problem.

  In addition, make sure the project is set up correctly, with the properties of the media source corresponding to the preset of the project.

  See Edit project settings switchboard to check the settings of the project especially if the project ones automatically.

  A lot of things to consider.

  Please consider. If you need additional information, feel free to ask.

  Thank you.

• By aligning multiple video and Audio tracks

  I am a multi-instrumentalist and worked on videos of my songs.  I save in Adobe Audition CC.  I've usually will start to record the audio/video with my Nikon D3200 as well as with studio microphones that record in Adobe Audition.  I add then several tracks on this track main video/audio recording to play the electric bass, banjo, mandolin, and percussion etc.  I mix all the tracks and send video clips to make a video in Premiere Pro.  I found that the main (usually guitar track) syncs perfectly with the video camera that I put in the calendar when you use the synchronization in the first feature.  From what I've read, if it is only possible to do this with a video and audio track.  I need to find a way to be able to align the other video sequences with the main audio.  Does anyone have a workflow that make this process easier for me?  Is there a way to do what I'm maybe missing out on Premiere Pro?   Please help me if I can continue the creative process!

  This is an example of what I'm doing https://www.instagram.com/p/-snqVSwzft

  I had to align that laboriously trying to watch the movement of the hand, but there must be an easier way.

  Audio and video synchronization begins to shoot and carries through to the edit and mix.

  Create sync audio and video synch and they will line up in the chronology of the edition.

  A simple way for you to do is a snap of the hand or a tap pronounced on the handle.

  Pro is use timecode in photo and audio recording device.

  Click on the titles and click count-ins are useful for musicians when more dubbing and overlay track.

  Its nice also.

• Capture VHS in Premiere Pro 2015, choose the option to capture video and Audio, doesn´t work!

  I used the first Pro CS6 and Premiere Pro 2014 before capture VHS via a record JVC deck, but now, when I do the same process in Premiere Pro 2015, it captures only the video in the option Capture Video and Audio mode. The only way to capture VHS audio is her choose Audio separately, because in this mode, it works. But then I have to synchronize video and audio, and it is not the best option. I can´t find no reason or settings which differs before when it worked. Do you have any suggestions?

  I use Mac OS X 10.9.5.

  Hello! I found the solution. The novelty in first Pro 2015 is that you mark a video and an Audio track to drag the material captured in the Timeline! Now, it works fine.

• Variable rate video with Premiere Pro

  Variable frame rate video comes from a lot of places these days: phones, live video streaming.

  Adobe Premiere is a so-called level piece of software production that took a good part of the change.

  How is it 2012 and Adobe does not yet have an answer to this problem?  After trying video editing/convert/mux/change image variable rate for 5 hours, I'm just exhausted.  No amount of conversion apps, etc. don't have saved us and THEY MUST NOT HAVE TOO.

  We have spent thousands on software over the past decade, Adobe probably 10s of thousands, and the only answer I always find is to move to Las Vegas.

  Surely, SURELY someone from Adobe with the vision of the issue can help answer the question of whether users moving in a different medium should find a place elsewhere in the software ecosystem...

• How to change the constant variable rate?

  Hello

  I export an HDV mpeg file that has a constant rate of a video H264 (.mp4) video for download on a web-based video player. I actually use the preset in Media Encoder 'YouTube HD 720 p 29.97'.

  The web interface of video online that I use requires a constant rate. But when you look at the video in MediaInfo it shows the video file as a variable rate. After looking through the settings in Media Encoder I found no option to fix this.  I see where you can change the frame rate and it is 29.97. So you might think, it would be constant but is not. And there is not any settings, I see, to change the constant variable. I don't see the flow settings, but this isn't the issue.

  I also have Apple Compressor and making a successful rate constant, but if possible I prefer to use Adobe Media Encoder. If anyone knows how to change this setting? Thank you

  Hi CLCTV,

  To close this thread, interpreted as variable rate exports are now interpreted as constant in the CC SOUL 2014 (8,0) and later. Please create a new thread if you are still having trouble with this problem.

• Length maximum Blu - ray HQ with H.264 and audio 5.1

  Greetings,

  I'm trying to get through my first project after the upgrade to CS6 and although I searched on this subject, I have not found a solution.

  Previously, I used CS5 and encoded in MPEG-2/HQ/VBR2 1440x1080i (corresponds to the source) and coding for 5.1 audio Surcode produce of the Blu - Ray.

  It seems that CS6, and improved video codecs, the impulse is to start using the H.264 or MPEG-2.  Don't I have that right?

  I am aware, there seems to be some problems with 5.1 audio and different encoding presets, but I do not like I encode my audio and video separately in order to bring them in again.  Impossible to believe that we STILL have to do that...

  Anyway, if I am not mistaken, it is preferable to use H.264 now, so my question is this:

  What is the duration of maximum quality project (which fits on one disc BD SL) if I use H.264 as the encoder of 1440x1080i, high quality, with a 5.1 audio soundtrack?  My source material is HDV if it matters.  I guess a related question is with H.264, what are the recommended settings/bitrate in order to obtain a maximum or high quality with this codec?  I had it all figured out for MPEG-2!

  Thanks for the ideas,

  BJBBJB1

  It's an interesting question, although I have no SOUL CS6, only SOUL CS5.5.

  I do not think that the video codec should really matter for the calculation of the amount of space taken a particular, although transmission speed if you are using a rate higher for audio, which will count.

  for example. a video (no audio) encoded, particular long with an average bitrate of 20 Mbps with the H264 video codec would take the same amount of space as 20 Mbps video (no audio) encoded with Mpeg2 codec.

  These are the raw numbers:

  for example. (all other things being equal):

  A 2 hour Mpeg2 video encoded at an average of 20 Mbps would take about 17,58 GB

  A 2 hour video H264 encoded at an average of 20 Mbps would also take about 17,58 GB

  It seems that CS6, and improved video codecs, the impulse is to start using the H.264 or MPEG-2.  Don't I have that right?

  I do not have CS6, but in terms of image quality at a given flow, H264 should give a better image quality than Mpeg2.  (as a very rough idea - and that perhaps not quite correct, but I think at low bitrates (around 10 Mbps?)) H264 is supposed to be equivalent to a mpeg2 to double the speed of transmission).  for example. 10 Mbps H264 might look roughly the same as a 20 Mbps Mpeg2 video.  Although at much higher rates and the same resolution HD, the difference will be less, or so high enough bitrate, it probably will not be a difference).

  I do not have CS6, but I guess it also depends on how much space the audio track takes up.  You use a codec audio lossless or loss?  About what average bitrate is your audio (if this will depend on what your audio lossless)?

  Unless she uses a higher rate for audio, the duration, you can keep on with H264 would be identical to Mpeg2 - although H264 should give you a better image quality than Mpeg2 the same transmission speed, you could probably reduce the video bitrate compared to how you would with Mpeg2.

  My brute (perhaps not entirely accurate) Calc:

  Total average bitrate 18.9 Mbps would give you about 3 hours of video with audio on a 25 GB disc (for example if the audio was about 4.1 Mbps and video 14.8 Mbps).

  Total average bitrate 28 Mbps should give you about 2 hours of video with audio on a 25 GB disc

  Total average bitrate 35 Mbps should give you approximately 1 hour 37 minutes of video with audio on a 25 GB disc

  ---

  In the preset for ' level Bitrate: high "in CS5.5, with a resolution of 1440 x 1080, with a high profile, level 4.0/4.1, it gives a flow target for video (no audio) of 18.75 Mbps

  If we assume audio is about 4.1 MB/s (the real value will depend on the real Mbps of your audio files),.

  This would give a total average bitrate (video + audio) of 18.75 + 4,1 MB/s = 22.85 Mbps

  To 22.85 Mbps total for medium flow, it should give you about 2 hours and 29 minutes (ie. about 24,94 GB), but you would need to leave a little space for menus (maybe assume the durations you can adapt are a little less that this is safe).
