Can't download 60FPS Youtube video

[Nicholas Steel]

Since Youtube finally made the HTML5 video player the default video player I've been looking for add-ons or mods that can enable me to download them. At the time, Video DownloadHelper didn't support 60FPS video downloading. This process works but the download stops prematurely, I can't download the full copy of the 720p 60FPS version of this video (only 200~MB's is downloaded before it stops).

I noticed that the current version of Video DownloadHelper mentions 720p and 1080p 60FPS video qualities in its list of video qualities, but they aren't available to choose from when looking to download this video. Any ideas? Any help?

Firefox 36.0.1 with the relevant MSE stuff enabled in about:config, Windows x64.

Are you really sure it stopped before the end ? 720p 60FPS is an adaptive variant on YouTube (which means it downloads video and audio separately) and it requires the converter to be installed (which i assume you managed since you could start the download). Once the downloads are finished, it takes time for the converter to aggregate both files to a single one. You can monitor those operations from the VDH panel, in the "Running" section.

Yes VDH5 is able to handle those variants but they must be available at YouTube. If you upload a high resolution video to youtube, they will convert it to a bunch of other formats with various qualities. But if the original uploaded video has a mid/low resolution, they cannot recreate the higher resolution, so 1080p for instance may not be available.

Yes, when downloading it via that Greasemonkey script approach the FIrefox download window shows the download size as around 700MB but the download always stops at around 200MB. Playing the video in Media Player Classic confirms the video didn't completely download. The download includes both video and audio in a single file, it is not of the variant where audio and video are separate files.

I'm aware that the author has to upload in a specific format for you to be able to download the video in that format, I'm also aware of how Youtube distributes uploaded videos (That it is converted to various formats etc). The video is clearly available at 720p 60FPS as evidenced by both being able to choose that quality in the Youtube video player as well as in the Stats for Nerds interface you can access via Right-Clicking the video player.

The partial downloaded copy via the Greasemonkey script approach is 60FPS according to Media Player Classic and motion in the video is as smooth as playing the game on an emulator/the original console.

I just downloaded the 720p (non ADP) version of this video (https://www.youtube.com/watch?v=wZUQDZEUbDI&list=PLz8YL4HVC87Wugs2z_-wHwrMcDwX85TGA&index=141) and it created a 914670892 bytes file without problem.

Once VDH has initiated a download, it doesn't do anything more until the download is completed. So if the download stops in the middle, the problem is not to be looked with the add-on itself. Any restriction you may think of (ISP, antivirus, disk problem, ...) ?

Ok, i mis-understood the problem.

VDH handles too many variants to display them all. The number of displayed variants and the order of preference can be set from the settings "Video Qualities". Check "Advanced" to access adaptive variants.

I've configured VH to display up to 20 different qualities of the video to download, only 10 get listed, none of them are 60FPS. I have also tried re-arranging the Quality list in VH's settings, I've tried moving the 60FPS qualities to the top of the list as well as the bottom of the list.

 The failed download occurs when using the Greasemonkey script approach, I can't get VH to even begin downloading a 60FPS copy of the video so I don't know if that would fail part way through the download as well.

I have attached 3 screenshots showing for that sample video:

- the 720 ADP variant in the list
- the details for this variants showing it is 60fps
- the Video settings to get this variant in the displayed ones

Cool, well now I have some new questions:

1) Why is the converter required when other methods can acquire a (partial copy of) 60fps audio&video file without any need for merging them together?
2) Anywhere else to get the converter from other than the VH homepage? 12KB/s is exceedingly slow.

I don't know. Maybe this variant is also available in a single audio+video file.
