    Youtube downloads

    Hi all

    I do a lot of music clip downloading from YouTube and as we all know the video quality might look perfect on the original source, but once the clip is burnt into DVD the playback on a stand-alone TV is disappointing as the picture ends up being pixelated.
    This may be a dumb question, but does anyone know if it is possible to ‘de-pixelate’ the video content??

    Thanks in advance for any answers or suggestions.

    You are apparently downloading the low quality versions of the files. Its not possible to add detail that isn't there. You need to download the high resolution versions of the files. Search "How to download 720p or 1080p video from YouTube" for instructions and the required software.

    Hi all

    Many thanks for your suggestions - 4 things I should have mentioned from the very start:
    1. I'm no computer geek (meaning I download at the highest possible resolution on offer)
    2. This pixilation issue only affects some downloads (as 480 is the highest resolution available to choose from), so I have my doubts whether de-pixelling is possible at all.
    3. Most downloads-when viewing the playback on TV-are absolutely perfect, meaning the TV or DVD disc aren't at fault in any way.
    4. I save everything as a MP4.

    You just answered your own question. Most Common Video Resolutions are the following ones:

    352 x 240 (240p) (SD)
    480 x 360 (360p)
    858 x 480 (480p)
    1280 x 720 (720p) (Half HD)
    1920 x 1080 (1080p) (Full HD)
    3860 x 2160 (2160p) (Ultra-HD) (4K)

    Most modern TV’s use 1080p or 4K. 720p is also called HD but is usually used for laptop screens these days. 480p and lower will not display properly on a big screen. There is no way to make 480p look good even using the best scaling algorithms.

    Basically, no. If you've downloaded a clip and found it pixelated then you're stuffed. You can't 'upscale' a low quality source.

    I suggest you have a look at a tool like youtube-dl, a command-line program to download videos from YouTube.

    I used it, together with AutoHotkey as a front-end, to build my Dad a 'YouTube downloader' that met his needs regarding audio and video quality.

    Hope this helps...

    PS - If you're interested then have a look at my QAD (Quick And Dirty) downloader. It's very basic with little or no error-checking but I still use it - 3 years on - as an easy way to download YouTube videos free from adverts

    Nope, not you. The project has apparently changed since I last downloaded the executable... which can now be downloaded from here. Thanks for bringing this to my attention.

    I'm unable to update the AutoHotkey page I originally posted my code to as it's now an archived forum.

    Here's a newer version (QAD v3) which includes a built-in updater:

    Code:
    ; http://www.autohotkey.com/board/topi...be-downloader/
    ; 
    ; v0.1 (17/02/2014) was a very basic downloader.
    ; v0.2 (19/02/2014) added updating of youtube-dl.exe after I realised it's updated frequently.
    ; v0.3 (01/03/2014) amended updating of youtube-dl.exe (Thanks to Garry)
    
    #NoEnv                              ; Recommended for performance and compatibility with future AutoHotkey releases
    SendMode Input                      ; Recommended for new scripts due to its superior speed and reliability
    SetWorkingDir %A_ScriptDir%         ; Ensures a consistent starting directory

      MsgBox, 64, QAD YouTube Downloader, % "The video has been downloaded."
      youtubeurl=
      return
      }
    return
    I've just checked a few minutes ago and it's updated the youtube-dl.exe to the latest verstion. Sorry the interface is a bit clunky. I lost interest when I realised it just worked as my Dad wanted so haven't bothered adding any more features like 'select quality', etc (even though the executable allows this using, for example, switches for bestvideo or bestaudio). By default, it just tries to download the best available quality anyway.

    You might, however, want to have a look at Format Selection if you want to change the download format.

    My script still works how I want it but I wrote it back in 2014 and, looking at the youtube-dl page on GitHub, the author made several changes at the end of April 2015.

    Hope this helps...

    Pardon my "ignorance" Rick, but what do you mean by: "Copy/paste it into your C:\Windows folder (or anywhere else that your PATH statement includes)."

    In other words, how do I do step 2 of your instructions on the other site?

    With QAD v1 I suggested you download and copy the youtube-dl.exe file to C:\Windows. I've made a number of changes to the AHK script since then. With QAD v3 it is no longer necessary to copy the youtube-dl.exe file to C:\Windows. Instead, just create a folder (e.g. C:\QAD) and put both the script file and youtube-dl.exe file in it together.

    Hope this helps...

    The easiest way to download videos is to use the online down-loader Keepvid. You just paste in the url of the video and choose the format you want. Ignore the desktop and pro versions as they are paid for. It also reacts faster to any changes made by YouTube.

    https://keepvid.com/

    There are also lots of browser addons/extensions available, but most don't work with the new YouTube format as yet.

    The best high resolution videos I have seen online, if you want to explore some, are from the BBC.

    For reference, HERE is a blog about it in general, and HERE are some links, along with THIS, and THIS.

    For recording I use (paid) Audials One, which I find satisfactory.

    Sorry Rick. My "ignorance" is still getting in my way. I guess I need an Idiot's Guide to running what you've created.
    I copied the text from above and 1st saved it as a txt file, and ran the dl. exe . . .nothing.
    So I renamed the txt file to a vbs file and ran the dl.exe . . .again, nothing.

    Obviously I don't know what I'm doing, so I really do need an Idiot's Guide.

    It's not your fault at all. The instructions in the AutoHotkey thread I linked to were more than 3 years old, very basic and made some assumptions about familiarity with AHK. Bear with me and I'll knock up some new instructions that are more informative and up-to-date.

    EDIT: I've re-done the instructions from scratch 'cos I only had a Win 10 PC to play on. Have a look at the An AutoHotkey front-end to the YouTube-dl command-line utility thread.
