Removing repeated frames from 25fps files on Vevo (originally 23.976)?

[digitalfreaknyc]

The file I downloaded was 30p.

From youtube or from vevo?

From Vevo:

You're downloading a very LQ version. Try grabbing the 1080p version.

Try grabbing the 1080p version.

Link?

But if the 1080p version is just the 360p version upscaled, you'd be better off starting with the 360p verion and upscaling it yourself. Recreating the missing frames from a decimated video is going to be very hard.

The link is on the first page. I'm not sure where you got the link for the 360 version. Even if I try to download it from the original link, it's still 25fps

Interesting that only the 1080p version gets messed up . One of the lower bitrate 720p versions was 30p and ok

youtube-dl is one way to access all the different versions



But the "best" version is 25p "hls-amazon-6006-2" - which was the one I checked out earlier with the dropped frames

"http-amazon-High mp4 1280x720 2128k , h264@2000k, aac @128k" was 30p and ok

You can check one of the lower bitrate 1080p versions , or maybe one of the other 6K bitrate versions @1080p, or maybe higher bitrate 720p versions. Or maybe it's the http versions that are ok, and the hls versions messed up. I don't really care for checking them all out , but interesting to know. I had assumed that they would all get the same processing

Very cool. Thank you so much!!! And these were all from youtube-dl? I've never used it. I always use masstube

[jagabo]

The link is on the first page.

The only link I saw was a link to the vevo page.

I'm not sure where you got the link for the 360 version.

I just right clicked on the video and selected "Save Video As". Or "Copy video URL".

What browser are you playing back in?? Firefox and chrome don't give me the option to save the video.

And, also, youtube-dl doesn't help me in the least, unfortunately. I know nothing about command line programs and the only GUI for it doesn't give you all those options that poisondeathray mentioned Back to square one...

[jagabo]

What browser are you playing back in?? Firefox and chrome don't give me the option to save the video.

I usually use Firefox but I have it so heavily protected it can't play videos from vevo. I used Internet Explorer to download that video. But I suspect the Save As option is only available because some server is blocked in my hosts file.

[poisondeathray]

Well IDM can access several versions, it's easy to use (push a button), but it's not free

There are several youtube-dl GUI's , it might be worth looking at some others .

Or bite the bullet and start learning about command line . It's really not that difficult for basic usage. Now is a good time to learn , with all the youtube changes (VP9, opus) and version types - you have full control of what audio or video streams you select. youtube-dl gets updated very frequently to reflect changes in various websites (it downloads from many sites, not just youtube). Sometimes there are big changes, and that will break a front end for it. You might have to wait a few days or even weeks for a GUI to get patched, but the CLI usually gets patched the same day. Also other commonly used programs like x264 , x265, ffmpeg - also require CLI usage to harness the full potential as well

I already pay for IDM as well. It could download 30 versions, none of which included a 30fps version, unfortunately.

Is there a good primer for figuring out command line? I literally know nothing about it.

[poisondeathray]

you seriously downloaded and checked 30 versions with idm (!) ??

which windows version are you on ?

You just open a command prompt . While you are in a given directory in windows explorer, Hold shift key and right click => open command window here

enter youtube-dl -F [address] to get the printout similar to the one posted above

This was the exact command

youtube-dl -F http://www.vevo.com/watch/billy-joel/All-About-Soul/USSM20402900

It's case sensitive, the capital "-F" is to list the tracks. Lower case "-f" is to select formats

So for example , when I tested the 720p low bitrate version (ie. http-amazon-High), I used

youtube-dl -f http-amazon-High http://www.vevo.com/watch/billy-joel/All-About-Soul/USSM20402900 -o 720p_amazon.mp4

You can mix and match audio and video with some eg. youtube. For example it might be -f 135+140 to have a given specific video and audio track (it will make more sense when you see a list from youtube)

-o specifies the output filename and path. Since I didn't specify a path, it uses same directory where I opened the command prompt

But the exe has to be specified in the path - If you use it frequently some people set up an environment variable, so you can call it from anywhere. That's the way I do it with various commonly used exe's like ffmpeg . There are plenty of step by step tutorials with screenshots for setting up environment variables, so take a quick peek on google . Or you can just manually specify the location. For example if youtube-dl.exe was in c:\folder

"c:\folder\youtube-dl" -F http://www.vevo.com/watch/billy-joel/All-About-Soul/USSM20402900

[digitalfreaknyc]

you seriously downloaded and checked 30 versions with idm (!) ??

It took no time. You can download all at once. Then I checked the FPS in windows explorer. Almost all said 25fps, aside from a few of the lower resolutions that had 15 and 10, I believe.

which windows version are you on ?

10

You just open a command prompt . While you are in a given directory in windows explorer, Hold shift key and right click => open command window here

enter youtube-dl -F [address] to get the printout similar to the one posted above

This was the exact command

youtube-dl -F http://www.vevo.com/watch/billy-joel/All-About-Soul/USSM20402900

It's case sensitive, the capital "-F" is to list the tracks. Lower case "-f" is to select formats

So for example , when I tested the 720p low bitrate version (ie. http-amazon-High), I used

youtube-dl -f http-amazon-High http://www.vevo.com/watch/billy-joel/All-About-Soul/USSM20402900 -o 720p_amazon.mp4

You can mix and match audio and video with some eg. youtube. For example it might be -f 135+140 to have a given specific video and audio track (it will make more sense when you see a list from youtube)

-o specifies the output filename and path. Since I didn't specify a path, it uses same directory where I opened the command prompt

My mind sorta exploded reading all that. I'll give it a try and see how I fare. Thanks for the info.

Interesting that only the 1080p version gets messed up . One of the lower bitrate 720p versions was 30p and ok

But the "best" version is 25p "hls-amazon-6006-2" - which was the one I checked out earlier with the dropped frames

"http-amazon-High mp4 1280x720 2128k , h264@2000k, aac @128k" was 30p and ok

You can check one of the lower bitrate 1080p versions , or maybe one of the other 6K bitrate versions @1080p, or maybe higher bitrate 720p versions. Or maybe it's the http versions that are ok, and the hls versions messed up. I don't really care for checking them all out , but interesting to know. I had assumed that they would all get the same processing

So I have to thank you because, as you said, I bit the bullet and figured out youtube-dl. You're right. On all the videos that i checked, all of the "amazon-high" videos were 720p and were 30fps. Unfortunately, that fit for all videos, even those that are 23.976. And there was also much more compression on the 720p files than the 1080p. So that completely throws out the idea that these files are upscaled from 480p (or whatever resolution).

I really don't get what master they have over there. I'm still having to use the tdecimate for the best quality but that's not possible for the files that are 29.98.

Yes, the 1080p image quality is still better here. The 720p is encoded with poor settings and relatively lower proportional bitrate . But for this specific case, the frame drops are far worse IMO. I suppose one method to improve it might be to insert the missing frames back into the 1080p version , derived from the 720p version

For the 99% of other cases (ie. "regular" music videos) , the native frame rate is "24p" . And choosing the 1080p25 version is usually the best choice, then using one of the decimation methods earlier in this thread.
