Videos stuttering

[Wilhelm Bauck]

Dear Support,
the videos I download are stuttering. The sound is OK, if not good, but the video stutters from start to finish and constantly. What settings can I make to prevent this from happening again?

Watching the video in VLC media player is said to correct the problem but if you want to get the video that is stutter free then you

need to change a setting to HLS as M2TS. My opinion is this should be enabled by default for all users.

Hi,

It is in the settings page, 3rd tab "Behavior".

Thanks 'mjs' for the solution, the stuttering video put me off using VDH before as I already had another HLS downloader that downloaded as .mp4 without the stuttering, but that now suffers on finding the download link, so VDH is now working well for me with HLS downloads.

Just sharing back some tips about the m2ts download format and how to quickly convert them to mp4 if preferred and another useful tool below to correct already downloaded videos that stutter.

MediaInfo (light, bundled with MPC player) suggests the following extensions are more suitable for the m2ts format: ts m2t m2s m4t m4s tmf ts tp trp ty (changing .m2ts to .ts can make the file more compatible with players and devices).

To quickly convert (in seconds and without loss) to .mp4 (mp4 container) then you can use 'Convert' in VLC player, on top menu 'Media -> Convert / save'. Then add the file (or files) and at the bottom drop-down select 'convert'. In the settings (of the 'Convert' menu) select the convert option and leave others unselected, then click the 'create new profile' button to create a mp4 conversion profile (first time only) as follows:

In 'Profile name' enter 'Video DL to mp4' (or the name you prefer). 1st tab is 'Encapsulate' select option 'MP4/MOV', 2nd tab is 'Video codec' select options 'Video' and 'Keep original video track'. 3rd tab is 'Audio codec' select options 'Audio and 'Keep original audio track'. Press 'save' to save the profile.

Continuing on the 'Convert' menu, you can now select the new profile (above), press the 'Browse' button to specify the destination (change extension to .mp4), then press 'start' and the conversion should complete within seconds. If you added more than one file then they will all be converted (one after another) with the .mp4 extension added to their original names.

If you already have some stuttering downloaded videos that you want corrected then the following free video editor can help:  avidemux.sourceforge.net  I'm still using the final 32bit windows version (avidemux_2.7.7 r210228) from 2021 and it works well (see the nightly download link at the top of it's web page). Once installed then open those stuttering mp4 videos and you'll get a warning about errors in their B frames, select ignore / cancel (i.e. don't correct them). With the video now loaded it should play without stuttering, if so then you can use that tool to re-encode it as required.

I hope the above is useful.

Thanks for you contribution.  It might be easier to follow if you include screenshots.  Here's some examples.  Start here:

https://groups.google.com/g/video-downloadhelper-q-and-a/c/BzPLK2YyL-s

That is the Table of Contents.  The first link in there navigates you to a tutorial on how to use VDH.  The style of that is based entirely on screenshots.  At the time I wrote that, I was unable to embed images within a post here.  At a later time I regained that functionality.  I suspect there was some incompatibility between Google Groups & Firefox that surreptitiously got fixed in Firefox at a certain point.  You can see an example of images embedded within narrative by looking for another reference within the Table of Contents.  Look for "cannot download" within the text of the Table of Contents web page.  That will give you a link to another tutorial that employs a different style, one I expect would be more suited to the information you are trying to impart.  You might find those 2 tutorials beneficial on their own merits.  But my purpose here in pointing them out is to show you a couple of styles of tutorial that are better than the "wall of text" approach.  You know, the old "a picture is worth 1,000 words" concept.  A lot clearer, too.

When it comes to converting videos, VDH itself is also able to accomplish that operation.  I suspect you can also do it with ffmpeg but that is likely more intricate, although probably gives you more options.  VDH uses ffmpeg internally so it is likely preferable for most people.

Having said all that, I would like to get my hands on the videos you say have been stuttering for you.  I would like to investigate them to see if I can discover some reason for the stuttering.  But you haven't provided any URLs of videos.  And by you, I mean neither Wilhelm Bauck nor Luca Lolli nor John DN has provided a proper problem report.  There are instructions for providing a proper problem report in the Table of Contents.  It should not surprise you that you can find those instructions by searching for "problem report" within the text of the Table of Contents.  You can also see instructions for how to provide a proper problem report by looking at the top of the home page of this Google Group.  Just click the Conversations link that appears in the upper left area of every page of this forum to navigate to that home page.  People should always post proper problem reports, not to satisfy some pedant's expectations, not to just follow rules, but because a proper problem report provides information that will allow other people to investigate your problem & perhaps offer you a solution to your problem.  A proper problem report is always in YOUR best interests.

While I'm here pointing out references in the Table of Contents thread, here's a couple more:

I am gratified to see that you, John DN, have avoided the stealth quotes.  You are setting a good example.
