Creation of multiple sound tracks when improrting a 5.1 video clip into the time line

Hi,

 

Since sevreral decades, I have been using several versions of Premiere Elements and several models of Sony video camera. My present equipment is based on:

  1. Premiere Elements 19.0 (20211007.daily.2243969) purchased on Fall 2019 and installed on a powerfull desktop Dell computer (Precision 5820 Tower X-series, 32 Gb RAM, NVIDIA Quadro P4000 8 GB graphic card, Win 10 21H2 version, x64), using currently the Expert mode,
  2. Sony HDR-CX740-05-30 video camera, producing 50p-HQ 5.1 video clips (MTS files).

 

Since early 2022, I face a strange behaviour when importing these MTS video clips into the time line of a Premiere Element project (selected configuration: PAL / AVCHD / AVCHD 1080p50 5.1 channel). Instead of importing the sound track of each clip into track 1 of the time lime, as it used to do before early 2022 using Premiere Element version 19.0 (or former versions), the sound track is now imported into 6 parallel sound tracks, namely sound tracks 1 to 6. Moreover, there 5 unnecessary copies of sound track 1 cannot be deleted without deleting the whole clip. This is especially anoying when other sound tracks or video and sound tracks need to be inserted parallel to the first clip.

 

After numerous assays, I have discovered a lengthy manual procedure for deleting such unecessay sound tracks 2 to 6 on each video clip (right click on the video clip inserted into the time line):

  • Dissociate video and sound track(s),
  • Delete manually sound tracks 2 to 6, leaving sound track 1 unmodified,
  • Associate video track 1 to sound track 1.

At that time, video track 1 and sound track 1 are now linked and may be moved easily within the time line.

 

My question is very simple, where this strange behaviour of copying sound track 1 to sound tracks 2 to 6 comes from? Is there any Premiere Element preference pattern that I have not configured correctly or modified without notice? Is the evolution of Premiere Element 19.0 software responsible for such a strange behaviour (I have noticed that my NVIDIA Quadro P400 graphic card was not "recognised" by Premiere Element 19.0 when I purchased it on Fall 2019, but that it is now recognised and used for improving the software speed)?

 

Any suggestion for solving this strange behaviour would be appreciated by participants of this Forum of by Adobe staff.

Sincerely,

 

Daniel-T from Paris

 

PS: MTS files have been copied from my video camera directly to my compurer disk, without using any special software. Furthermore, each MTS file has been imported into Premiere Element 19.0 project either directly (Import function) or using Adobe Element Organizer 19.0: the result is identical, in terms of the strange behaviour described above.

Correct answer Daniel-T

Hi,

Here are the conclusions of the comparison of both methods for getting arround with the unability by Premiere Elements 19, since its last 2021-11-07 update, to handle correctly 5.1 Dolby MTS files.

  1. Deleting the 4 inapropriate audio tracks which appears when MTS files are added to the timeline requests, as mentionned previously, numerous operations for each video clip (at least 6 steps); quality of video track and of sound track appear not to be altered by such operations.
  2. Converting each 5.1 Dolby MTS file into a stereo MP4 one, requests to learn how to configure Handbrake.fr software (not straitforward at first), to acheive the conversion (batch conversion is possible) and finally to modify the MP4 clip creation date, so that it is equivalent to the original MTS one, using Organizer Elements as a tool to modify EXIF data.

 

Having acheived both procedures for a set of MTS video files, I prefer using the second mrocedure, namely the conversion using Handbrake.fr. My major concern was the loss of video quality during such file conversion. Sofar, quality of video and sound track of converted clip files appear as good as the original ones. This was not obvious, since resulting file size is much smaller in MP4 container than in MTS one (ratio = 164). Furthermore, MediaInfo software tool tells, for example, that video flow rate is more than 300 times smaller within the coverted file (15.2 Gbps for original MTS file vs. 41.8 Mbps for MP4 converted one, using High L4.2 quality factor).

 

Using my usual Premiere Elements 19 film production parameters, namely AVCHD 1080p50 (H264, 1920x1080p50, VBR2, 10-20 Mbps), resulting quality of the MP4 film file appears equivalent to those of film produced before 2021-11-07 Premiere Elements 19 update, using the same film productions parameters. Of course such comparison is very empirical and I have no quantative indicator for assuming such video quality conservation.

 

In conlusion:

  • Thanks to inacceptable evolution of Premiere Elements 19 software, after its 2021-11-07 update, I have spent a lot of time and effort for getting arround the 5.1 Dolby MTS issue. Other post on this forum demonstrates that I am not the single user facing this issue.
  • I find really non-professionnal for a company like Adobe to avoid any notification to Premiere Elements users related to the 5.1 Dolby MTS issue.
  • Moreover a 2022-01-13 official article named 5.1 audio import assumes that such import is possible, which is clearly not true, even for the 2023 Premiere Element version.
  • Although this user forum is dedicated to software users, which I really appreciate, I regret the absence of any Adobe staff contribution on this post or on previous ones, to clarify this issue.
  • After several exchanges with Premiere Elements community experts, which I have greatly appreciated, I finally close this post, although I really feel that the problem is not solved.

What you can do is use Handbrake.fr to convert your 5.1 clips to stereo.

I did this in the past when I accidently set my Camcorder to 5.1 audio.

    Kind of ridiculous, one has to convert.

    Elements should handle 5.1 like any other video editing program.

      Thanks Ann for the wise advice to set my video camera to stereo instead of 5.1 Dolby sound frames. I have just made this modification.

      Nevertheless, I may add that, since my Sony HDR-CX740-05-30 purchase more than 10 years ago, all Premiere Elements versions that I have used , i.e. versions 11, 14, 17 and 19, have recognised and processed correctly 50p-HQ 5.1 video clips (MTS files). It is only after the 2021-11-07 update of Premiere Element version 19.0 that the above mentioned unnecessary copy of sound track 1 to sound tracks 2 to 6 have appeared. Sofar no further update has been suggested by Adobe to solve this issue. As you previously mentionned even 2023 Premiere Element version faces the same issue.

      Known issue which Adobe has not managed to fix not even in 2023.

        Only way to fix this is to set camera to stereo.
