Best Free Video Accelerator


Tired of video getting stuck? If so, you need a video accelerator software. This type of software uses a multi-connection algorithm that increases the download speed of a video, providing a smooth and non-stop streaming.

In reality, this could be compared to either filling a tank with water from only one tap or several. I have been searching for this type of software for sometime and after some research I came across these products included in this review article.

SpeedBit Video AcceleratorSpeedBit Video Accelerator makes videos from YouTube and over 100 sites stream faster and play smoother by reducing buffering problems and video interruptions or "hiccups". This software will drastically increase your flash videos up to 5x faster. After I installed it I couldn’t believe how much difference it makes, even when using internet for P2P downloading videos play smoothly. SpeedBit main window features a built-in video search tab for finding videos from different video websites, and a recently Accelerated tab where you can easily replay the last 10 videos accelerated.


SpeedyiTunesSpeedyiTunes smooths your downloads from YouTube, MSN Video, MySpace video, Yahoo Video, AOL video, Veoh and over 300 other video sites. Apart from accelerating flash videos SpeedyiTunes will also accelerate web file downloads, this is a bonus for users without a download accelerator. Another interesting feature is the instant saving of flash videos. You will be able to save your favorite videos while watching them, no need for a separate program to download videos. The main window features 2 tabs where users can check last accelerated videos and saved videos. A built-in video search is also provided.


My personal preference goes to SpeedBit Video Accelerator. This software does best in what was intended for, the acceleration of flash videos. After trying both products I noticed that SpeedBit Video Accelerator is more “aggressive” accelerating flash videos, making my choice easier. However, if saving flash videos is a priority I would recommend SpeedyiTunes.

DO NOT INSTALL SpeedBit Video Accelerator. It has HIJACKED my google chrome and internet explorer home page. The program was triggered to start with firefox as well. Some site has reviewed it as potential malware. The video speed doesn't seems to be faster using the program as well. I would not suggest this program.

I confirm the installation of SpeedBit produced hijacking of my Google Chrome h and Internet Explorer home page. Not only this. The setting of the router was impaired. I was unable to restore this condition, and the only option that I had was to re-install Windows. Number of hours lost: 12 (twelve).

We make it very clear in the program details that SpeedBit is bundled with additional components. There are many programs like this but the unwanted components can be avoided if normal care is taken during the install process. See this information page for more details. MC - Site Manager.

Speedbit hijacked my home page and I can't do anything about it because Speedbit also crashes Chrome. I finally threw in the towel and completely unistalled and re-installed Chrome. Speedbit still crashes it! I now face a lengthy ordeal before I can use Chrome again. Speedbit also hijacked Internet Explorer, which is not my default browser, but at least it doesn't crash IE so I could fix it. I'm now using IE until I can figure out how to make Chrome work again. Oh, I did uninstall Speedbit, but it still crashes Chrome every time that I try to re-install Chrome.

This may help you remove all elements in Chrome from speedbit - though the article is from last year!topic/chrome/TEenyy-YZJc

As is made clear in the product details, Speedbit is bundled with unwanted components. These can be avoided though if care is taken during the install process. Further information at the link below. MC - Site Manager.

Unfortunately, everything installed silently, giving me no options. A version that I installed a year ago did not have this "feature". My Registry is absolutely peppered with entries. You can get Chrome to run again if you stop the process "sbu.exe". Interestingly, when Speedbit was running, I couldn't seem to get to sites with descriptions such as "Speedbit removal tool."

I still have crap all over. Is it doing anything? I can't tell for sure. You won't be able to remove the Registry entries until you stop the process.

by bellhop on 13. February 2014 - 15:57  (114451)

Update on Speedbit: The version that I installed on another PC a year ago just started feeding me pop-up ads from the Taskbar (Windows 7). Sure, they have to make money. Maybe this future feature was buried in the fine print somewhere.

If you're a "power user", check out the files that Speedbit installed in C:\Program Files BEFORE you attempt anything. You might find some valuable clues. I also found links to "un-hijack" and "uninstall" that may work (I haven't tried them yet).

It's beta for Win7.

SpeedBit Video Accelerator
No HD video acceleration in the free version, wouldn't that be worth mentioning?

The new version of vac is forcing you to check both make speedbit search default and speedbit homepage, which I think is malaware, spyware, or adware type of program. Unistalling the vac also does not remove both the search and homepage, so I think vac is full of crap.

Thank you for the advisory. I have now added this to the product information details. MC - Site Manager.

In my case, Speedbit didn't improved Youtube video playback, in fact it was worse.

I uninstalled it and now my videos play again smoothly

by JustAUser (not verified) on 14. February 2012 - 3:53  (88811)

I have Window$ 7 Home 64 bit and Window$ Xp Service Pack 3 32 bit installed on an iMac and installed Speedbit Video Accelerator on both. There seems to be an increase in loading time and speed that videos play most noteably on MSN. So I guess it does what is says it going to do because the stuttering and waiting for videos to load is all but gone. Version installed was and except for the speedbit download bar offer it was clean. I used cclean to uninstall it and the program was completely removed. A search of the computer and registry turned up no left over entries on either computer. I have 12 mps cable internet access in case you were wondering. Over all I would say that Speedbit is a good program. The 1 and 2 year old comments about malware, browser hijacking and the like didn't happen with me. I haven't figured out why it doen't say a video is being accelerated but I supect that it would have something to do with the site you are viewing a video on and that site knowning that you are using speedbit. I haven't had a chance to test that idea yet but when I do if there is any interest I let you know. There doesn't seem to be a free version for mac but I am going to give the 15 day trial version a try and see what happens. Hope this helps somebody.

This needs updating, Now there is the new Speed Bit version and supports Vista. but i haven't done any testing or comparing on it. so an update to this site would be great.

Brilliant site, thats the only reason why i created an account.

Speedbit is bandwidth heavy and will slow video load times on certain sites to a standstill. YouTube appears to work OK but that's about where it ends. Other streaming sites I use will not be accelerated by Speedbit and therefore continue to stutter/buffer badly. Other accelerators appear to work across all streaming sites, whereas Speedbit is selective, exclusive... limited. SpeedyItunes wasn't much better either. Disappointed by these below average apps and reading other comments listed here I can see why. I am running Windows 7 with ADSL fast broadband. Also installed on my wife's XP Pro -> unsatisfactory outcomes. Two thumbs down.

I like SpeedBit because it accelerates online videos through my PlayOn server while connected to my Xbox 360. Wish ByWifi would do this because it works through all video web sites, as SpeedBit is limited to what sites the programmers add. Bummer! But I use SpeedBit for my PlayOn server and ByWifi for my PC when I'm on my computer.

its better not to use speedbit with slower dialyp connections

by Debaclee (not verified) on 26. August 2010 - 19:11  (56773)

The program SpeedBit is not just really bad, but dangerous.

Altera registration and the uninstall, disable Internet connection, which is restored only by using a specific tool called LSPfix.

The problem was detected in the HijackThis item 10: Winsock trouble.

There are not accelerators, can only be properly set up the latest version of Adobe Flash Player, if it works well, the videos are uncut and accelerators.

Ah, beware, there is another program on the market as dangerous as this is called Bywifi, take care of them.

by Xproject187 (not verified) on 24. July 2012 - 8:38  (96583)

Dude,of course there's guna be a discrepancy in Ur Winsock.
Speedbit changes the Default Winsock Settings/Files to allow connecting to multiple servers for the same file.
Like the Man said, "5 hoses to fill Ur Pool or just 1".

One click can cause thee inability to connect to the Net.
So Don't use it with-out qualified directions.

In the last 3 days I've scanned My entire PC with "eSet","Kaspersky","MBAM","TDSKiller",Combofix" & "UnHackMe".
Not 1 hit on Speedbit or My Winsock.

Anyone can scan Speed-Bits "Program Files/Folder"
(Come back & post a positive hit,when U get one?).

When a video needs Speedbits help,the tray icon will blink,however not all videos need help,in which case the icon will not blink.

Wow, I really get confused after reading all of those comments here. Somebody had problems with Speedbit Video Accelerator, while others said that the soft just works fine. I dont know what to do, men! I want to give it a try, yet I just worry that after installing it to my laptop, I wont be able to get rid of it completely. what a nightmare!

by Anonymous on 29. June 2010 - 2:48  (53413)

by Anonymous on 27. June 2010 - 2:02  (53228)

Not sure what's up with their own site, but the Softpedia link is still OK.

Bywifi Video Accelerator is hands down the best Video Accelerator out there is best of all it's free. I couldn't believe how well it works I mean I saw a huge difference when I have it running another cool thing Bywifi has other nice features like you can download and transcode the video all with the same program.

by morrig on 17. October 2010 - 16:34  (59669)

Do NOT USE this or may be any other of this type,I un- installed after juddering on some videos, and have lost all connections and after hours of troubleshooting and restoring system,have not yet found a solution,am typing this on another computer that automatically seen modem.
This on Win7 and Ubuntu Systems on computer so it seems to have affected the Realtec lan motherboard settings even re-installed drivers.

by Anonymous on 10. May 2010 - 10:16  (49455)

I am using Bywifi and i am quite impressed with it.I do see a noticeable improvement in buffering of the video while it is working.Also the facility to save videos while watching them makes it an interesting product.
