Why is Video choppy?
If the video is not playing continuously then there might be some problem with the internet connection. If the speed of the connection is less, it may affect the video buffering. The broadband connection of about more than 500 kbps would be required in order to get non-stop buffering from the internet. The download speed of the video must be fast to see that your video is not choppy. It is better to pause the video for some time until the total video is downloaded. Later, you can start playing it. Sometimes it may happen that the video might have been downloaded only partly and not completely into your system cache. Then the cache of your browser can be cleared off and the downloading can be done again.
While downloading videos from iTunes, even if your PC has good processor and high capacity RAM the video might get chopped. Watching movies through iTunes create problems in freezing the frames temporarily or videos usually getting slower and so on. The slow video buffering can be due to the video getting stored in SATA hard disk. It can happen even when the CPU is busy with processing many applications.
If the video is playing slow, it can be opened through QuickTime or VLC. The use of updated device drivers for the SATA hard disk will prevent the videos to become slow. If the Ready Boost in Windows Vista is enabled for driving the video then it can become slow. The option called Use high quality video setting when availableÃ¢â‚¬ in the QuickTime can be unchecked to reduce video chopping. The video will be slow or choppy if it is not opened in DirectX mode which can be selected in the preferences menu of QuickTime. It is very important to take care that only necessary applications are run along with video. Otherwise they may hinder the video which might result in choppy video play.
