How to Mux / Join Audio & Videos Files From keepvid Sites and Similar Ones?

[devilcoelhodog]

Hello, dear all.


As the title says: How to Mux / Join Audio & Videos Files From "Keepvid" site and Similar Ones?


For example: if I go to : http://keepvid.com/


And can get all the links from there ( audio and video files) and want to mux video and audio files, how to proceed?


Oh, almost forgot to say: I'm talking about links obtained from Youtube site. Maybe other sites works like the same way too.


Which programs can do that for me? ffmpeg is one of them? Any manual / tips how do to it using ffmpeg?


My goal is to pick up the best resolution videos like 1080p / higher (Video Only) and mux it with any audio available there.


Is that possible? Any convertion is possible concerning all 1080p / higher (Video Only) and audio files?


Thanks for helping.

Best regards.

You can mux with mymp4boxgui or mkvmergeui.

Or use other download apps like https://www.videohelp.com/software/4K-Video-Downloader , freemake video downloader, masstube that should get one video file.

Hello, dear all!


Thanks for helping!


I really enjoy 4kvideodownloader! :P


But, I could notice some "differences" when I download some videos using: 4kvideodownloader, "keepvid.com" site and and Video DownloadHelper.


I could grab 1080p (Video Only) using "keepvid.com" site. The video has no sound. See what I could find about its videos using MediaInfo:

Such video has no sound and and strangely is not seekable. No player can seek it. Only play or pause the video. Not convertions is possible too!

When I try to open it using Avidemux I cannot do it. Error. It seems no muxing is possible too!



When I try the program 4kvideodownloader on the same link I could get the video + audio
perfectly. See what MediaInfo says about it:

And when I use Video DownloadHelper I could get the highest resolution available!


The problems is that now such program put some "watermark" when convertion is done using such program.


The current / newer versions need registration to remove the watermark.


No problem at all, because I do not mind to pay for it.


I just wanna know if does not exist freewares available that can get such video / audio just like Video DownloadHelper does.


Comparing the same grabbed files using Video DownloadHelper and 4kvideodownloader it seems that ones from Video DownloadHelper have better quality that 4kvideodownloader can provide. Does it really true and happen indeed?


Even the sizes of them are different: from Video DownloadHelper has 29 Mb. And the 4kvideodownloader file has 20 Mb. Both in MP4 container. And all the resolutions grabbed are the highest that such programs can provide on their engines.


Maybe Video DownloadHelper could grab/ convert on higher resolutions that the others couldn't?


If I can't find freewares that can do it the grabbing in hightest resolution available I'll buy a license from Video DownloadHelper.


I just want to undertand the "differences" between programs and all outputs from them.


Thanks for the tips!


Best regards.
