Unable to post video to Youtube

Anyone else having this problem? I get the prompt to enter my username and password, which I do but no luck. The same prompt pops up again and again.

IT WORKED! I can view video again from YouTube. I removed all cookies for youtube in preferences and Page Info. Thank you so much! Now I know what to do if it happens again.

Are you still able to view flash videos and games from other sites?
If so and are from India then youtube videos among many other sites were blocked. https://support.mozilla.org/en-US/forums/contributors/710463

Post video to youtube bug

Very often when I select post video to youtube, after compressing the video it asks for some info, the categories list is empty and the category field is blank and I cannot select a category and so it wont let me publish. I have to cancel the upload and start again, second time it usually comes up with the category list.

You don't unless YouTube provides some way to upload to them via email or MMS.

Unable to upload video to YouTube

I have tried twice to upload a video to YouTube. It is a short video, 7 min 33 sec. I get the error, "Failed (unable to convert video file)". I recently upgraded to Mavericks & iMovie 11 and this is the first time trying to upload since the upgrade. Any suggestons?

Although I believe you when you say it worked after removing tags, I don't think there is a solid cause and effect. The web is loaded with complaints of the iMovie to YouTube upload. It is simply NOT stable. I used iMovie '11 with Mountain Lion and now use the new iMovie 10 with Mavericks. Yes, I said iMovie 10. Apple named it that way. Not me. The iMovie to YouTube upload option is unreliable. We all want to try to narrow it down to a font or a clip or a photo or a title or the duration or the HD resolution etc... In fact, we are wasting our time until Apple works out these issues. I made 20 upload atttempts today. All using an approx 4 minute clip. Trust me. I got "Failed (unable to convert video file)" several times and each time worked to focus on the problem. Nothing was logical. I would add a single photo to a project that had previously worked and it would bomb. I would then delete that photo and it would still fail.

I am unable to watch videos on youtube, it stopped last night. How do I fix this?

We had a storm last night and the power went out for a few seconds. After I started the computer, I tried to watch some videos on Youtube. I have been watching them all the time, but since the power went out I am not able to. It seems to be just on youtube. What do I need to do to correct so that I will be able to view videos on that site?

I have been having the same problem since a browser update a couple of weeks ago. I have tried uninstalling firefox and re-installing it. I have tried updating flash player, reinstalling flash player, re-re-reupdating firefox, even tried to find an alternative flash player (which turned out to simply be another adobe player with a different icon and filename). I have tried clearing cache and cookies.
I can watch videos from any website anywhere except videos hosted on youtube. I know this is not a youtube problem; because, I have not experienced this problem with any other browser.

I am unable to get videos on Youtube to operate from Firefox. They do work from Internet Explorer. Have tried youtube from Firefox in Safe Mode - SAME PROBLEM!!

Until now I've had no problem getting Youtube videos to show from Firefox. But now I've been unable to watch any videos (or audios) from the Youtube site when browsing in Firefox. When I go Internet Explorer and bring up Youtube the videos/audios play just fine. I've tried doing this under Safe Mode with the same result. No Youtube pictures from the Firefox browser.
I like Firefox but will revert to IE if I have to.

If I accept cookies, I am unable to see videos in YouTube

Yesterday I upgraded Firefox from version 3.6.13 to version 3.6.14 on two different machines (both of which use Windows XP). And then a very strange thing happened: after that I am unable to see YouTube videos. I can see hear the sound but there is no image (there is a white space instead). Furthermore, this only happens when I am a regular user, not an administrator. And it happens only with YouTube. The only way I found to fix the problem was to delete all YouTube cookies and to block any new ones. Then all works fine.

If you've an answer that works, that's fine. Problem may occur for various reasons, including flash problems and video drivers requiring updating.
As a temporary workaround hovering your cursor over the place where the pop-out button should be below the YouTube video screen, then left click there and the video will then display in the pop-out screen.

I am unable to play videos on youtube app or in safari ?

Hi,
My son has an ipad mini and for the last year and a half has spent many hours a week watching Minecraft videos on the Youtube app without any problems. About a week ago my son showed me that when trying to play a video via the Youtube app the audio would play fine whereas the video playback is stuttering and completely out of sync with the audio. I thought that it may just be the app so I tried watching a video via safari but it was the same issue. I then thought I would try watching movie trailer from a random website but that wont play smoothly either.
If anyone has any ideas on how to fix this I would be eternally grateful.

I Would start with something simple and easy to do. Close all apps, and reset the iPad, you will not lose any data.
In order to close apps in iOS 7, you have to drag the app up from the multitasking display. Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the app that you want to close and then swipe "up" on the app preview thumbnail to close it.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Unable to watch Adobe Flash / YouTube - OS X 10.6.6 - New MacBook Pro 2011

Hello,
I'm new to Mac family.
I recently got new MacBook Pro 2011 15" model. However I'm unable to watch videos on YouTube. It shows Adobe Flash Player is out of date. My MacBook Pro software up to date. I tried to download and install latest version of Flash Player from Adobe website. Installation went successful, but nothing works.
I tried on both Firefox and Chrome builds too. I even restored MacBook Pro to default settings. I'm just wondering, whether Mac supports Adobe Flash Player at?
Any further help would be greatly appreciated. Thanks.

Does anyone else have a solution to this issue that does not involve doing a fresh install of Snow Leopard? That solution is not acceptable to me.
I did a system migration from a Time Machine backup when I purchased my new 2011 MacBook Pro last week. All my applications seemed to be working normally until I attempted to watch a YouTube video in either Safari or Chrome. In both browsers, all I get is a black screen where the video should be playing.
I downloaded and installed the latest version of the Flash Player for Safari and I am not able to manually update the Flash Player for Chrome since that browser keeps the Flash Player up-to-date automatically. The black screen persists when attempting to watch a video on YouTube. I cleared the site cache for the Flash Player just in case something was buggy there, but the problems remains.
Any assistance would be much appreciated!

Pros and cons for posing video to youtube for use in iWeb

Hello
Can someone explain the pros and cons of posting video to YouTube for use in an iWeb website instead of iDisk?
Thanks
Carl

Carl ~ Some of the following points have already been mentioned above, but anyway...
Pros for posting videos to YouTube are:
Viewers of your video wouldn't be using up your limited .Mac data transfer allowance.
Once your site is published, if subsequently you have to do a +Publish All+ from iWeb, you wouldn't be uploading your video yet again to .Mac ~ saving time and usage of your limited .Mac data transfer allowance.
YouTube videos have a wide audience and popular features such as ratings, playlists, comments, etc.
Cons for posting videos to YouTube are:
Limitations on size and quality of videos and their unappealing presentation style. For example, compare YouTube's presentation style and limited size options with that of a +.Mac Web Gallery+:
http://gallery.mac.com/emily_parker#100471
Perhaps a compromise would be to post your videos to YouTube (for the publicity) and link from your iWeb site to a +.Mac Web Gallery+ (for its elegance and avoidance of iWeb re-publishing it.)

Unable to download or run any videos from Youtube

Unable to download or run any videos from YouTube. I can open the YouTube website, but when I select any videos, even ones I've posted myself in the past, from another computer, the video window opens and shows the "whirling circle" display that indicates it's trying to download, but nothing else happens. Meanwhile on the rest of the website window, other flash data continues to display and update.
This is not restricted to Firefox; same thing happens with any browser I attempt to use. Could be windows 7 related, but I don't know what other settings to check.

Try to disable the restrictions and reset the phone by holding the sleep and home button for about 10sec, until the Apple logo comes back again.
Are you using Wi-Fi? If yes, check your security software settings as well:

I cannot post comments on YouTube with Firefox anymore, but can on IE. Intermitant problem, some videos I can post to.

The comment box is grayed out on many, but not all videos. The problem is only on FireFox; I can go to the same videos on IE and have no problem posting comments. I have Windows 7 home premium, service pack 1, 64 bit. The problem is new, has been working properly till a few days ago. I refreshed Firefox to default settings, been through Youtube help menus, and Firefox help.

I tried restarting Firefox in Safe mode and then went and commented on a video and whalla it actually worked.... so then I thaught it must be a plugin problem.
I disabled all my plugins then re-enabled them one after the other until whalla I found the culprit!
The error is in the DownloadHelper 4.9.14 Extension Plugin, hope the Authors of this plugin are reading this, it is causing users commenting and posting errors in Youtube and needs to be patched!
Hope this helps others!
