Jumpy video captures

[Lance Alwood]

All the videos on any web page now is saved very jumpy and unusable.  This started a few versions ago and I'm not sure how to fix it.  Using Firefox 46.0.1 the version of VDH: Version 5.6.1a1 but this problem has existed in at least three version prior.

This happened when I got updates to Firefox and was forced to update VDH. 

The audio is fine and not choppy but the video itself is choppy or jumpy.  It's almost like all the frames of the video is jumping from one to another or it's skipping some frames or missing some frames. 

Is anyone else seeing this or am I missing an easy fix.  This problem occurs no matter what website capture videos from.

Any help would be appreciated.

Thanks

This problem has been reported for HLS and DASH videos downloaded with VDH 5.5.0+ and played on QuickTime.

But if you are having a problem with all videos, like this one http://lelombrik.net/68031 (which is a plain server-to-disk download), then the issue is definitely with your video player. You may want to use VLC as a player or use the converter to generate a video your player can understand.

I just confirmed myself that a DASH video downloaded from vimeo using Firefox 47.0 and VDH 5.6.1 results in a video that plays back choppy on QuickTime Player (OS X 10.11.5), but smoothly in VLC (2.1.5 Rincewind). Download + Convert (MP4 4MB) resulted in a very pixelated video. Convertling the local file after downloading without conversion resulted in file that plays back smoothly in QuickTime Player. I don't know why the straight download of a DASH video fails to play smoothly in QuickTime Player, but it would be nice not to have to convert it.

When converting the video to be playable on QuickTime, try the pre-configured output named "MP4 re-encode". This setup does not enforce the bitrate and adapt to whatever is used in the original file.

I am having the same issue now (7/31/17).

I haven't this issue until the last week or so.  I've downloaded via Mac and Windows.  Once I try to open it in iTunes or QuickTime, the video jumps terribly (on either machine).  the audio is fine, but the video is junk.

I'm downloading as an mp4.  The first time I downloaded on the windows, sent it to drop box (can watch it on Dropbox and it plays smoothly), but once I try and download to Apple its jumpy.  I also tryied to import the file directly into iTunes on the Windows laptop and its also jumpy.

Any guess as to how to fix?

As a new user of VDH, how do you convert after downloading?  Do you have to purchase a conversion tool or is it integrated into VDH?

Thanks for your help.

You need to install a converter that VDH will use in background. The converter is free and opensource, check http://www.downloadhelper.net/install-converter but the generated videos will hold a watermark. You can purchase a license to get watermark-free videos.

HOW DID YOU CONVERT THE LOCAL FILE AFTER DOWNLOADING?

Click the VDH button in the toolbar. The VDH panel opens. Pass the mouse over the "..." sign at the bottom left of the panel. New icons appear, one of them corresponds to "Convert local files" (just pass the mouse over the icon to see the tooltip with the command name).

Download VLC (free) .  I had the choppy video with OK audio and the VLC app worked just fine.  Mac OS X Mojave 10.14.1

Comment and question...I get smooth-as-silk downloads with the free version and only got choppy versions with the paid version.

1.  How do I need to re-render choppy videos to make them work?  handbrake? movavi?  what settings?  I'm not interested in having to use specific players (VLC) to make the videos work...I need them to work on any player, just like the videos from the free version did.

2.  What settings do I need to download usable videos?

it seems reencoding videos sometimes fixes the problem.

when you're not premium we add a watermark, and this implies a reencoding. that's why it sometimes works better with not premium.
