What kind of video is being played? If its HD on an older computer it could have choppiness problems. you can try going to Applications>Utilities>Disk utility. In there, Click your startup drive, and click repair disk permissions. If that does not work, you should reinstall your operating system. I can guide you through that if necessary.

A slowdown occurs on PowerPC Macs when watching movies in Windows formats (mostly WMV or AVI). A recent upgrade to Flip4Mac (the tool that allows Quicktime Player to play Windows-format videos) is the culprit, as it substituted very inefficient Silverlight code on PPCs for the efficient code in earlier versions.
The solution is to downrev Flip4Mac. Use the uninstaller tool in Applications/Flip4Mac. Then download version 2.2.1.11 of Flip4Mac from:
http://www.telestream.net/download-files/flip4mac-wmv/Flip4Mac-WMV-2.2.1.11.dmg
and run the installer. This will replace the efficient code and greatly smooth your movie viewing. If Flip4Mac urges you to upgrade back to the newer version, ignore it.

Sony VAIO vgatz750p has problems plating video. Playback is in almost slow motion and choppy


You probably need more ram memory. Also try playing a video in your dvd player. If it plays slow and choppy you definitely need more ram memory.

If you are trying to play a video from a website (streaming) then three things can affect how smooth it plays.
1) Memory - your ram memory might be low
2) The website might be experience heavy traffic from many users.
3) The Line Speed of your internet connection from your service provider might be slow. For example: AT&T sells about 3 or 4 different packages and each one increases the line speed for uploading or downloading. If you buy the low end package the line speed is very slow on uploading and downloading or streaming. It's ok for just surfing, but nothing else.

Choppy Video? What do you mean choppy video? Is the video starting and stopping rather than playing continuous? If so, either you need more memory or the site you are watching the video from is slow. Also sometimes you line speed on the computer might be slow if you are watching the video online.

How does the video play if you played a DvD in your computer? If it plays the DvD without stalling, then your problem is more than like the site you are watching or the line speed as you stream the video.

Whenever i upload a video to my computer it turns out choppy and slow. I downloaded Nikon Transfer and after using it my videos are still choppy. What do I do about this?


I'm a video game programmer with 20 years experience in software, and have a reasonable understanding movie playback software.

I also have a Nikon (S6100) and the problem is nothing to do with PC memory or CPU speed. The Nikon creates a broken version of the MPEG-4 AVC H.264 format, which results in choppy playback. I've tried Quicktime, VLC and the cameras own player - ViewNX2 - same result for all of them.

Converting the buggy .MOV files the Nikon creates to a .avi format produces perfectly smooth (flawless) video, but with the sound out of sync. I can also create perfect quality (lower res) DVD video, but with the sound missing.

I have spoken to Nikon about all this and they are quite simply clueless and will take no responsibility. As there is no firmware up[date for this camera I'm taking the camera back, as it is basically flawed.

I've read a few sites with customers complaining about choppy video for this camera, so it looks like the model itself is flawed.

I just upgraded my PC 300PL IBM computer's RAM from 128 MB, to 256 MB on each slot (3 slotes), When i watch videos from my pc, or videos from online sites, The playback is slow and choppy. I was wondering...


The problem is that the video-player on your computer is "starving" for audio/video, because your download-speed is not fast-enough to "feed" the stream.

So, when a video starts to play, click PAUSE, and wait for the download to proceed for a while; then, click PLAY, to view the already-downloaded stream.

E-System laptop with slow dvd playback


This can be a bit of a tricky one to figure out. My initial response would be that you have another program or process that is causing your computer to play 'choppy' video. When you have a newer computer that was recently working just fine and now all of the sudden the video is choppy, it is usually due to another process using CPU cycles that are so important to video playback.

Start playing a DVD, but don't go to full-screen mode. Open the Task Manager. Right-Click on the task bar and select Task Manager. Click on the 'Processes' tab. There is a column labeled CPU, click on the heading 'CPU' twice. This will order the processes in order from highest CPU usage to lowest. The top two processes will most likely be your DVD player and the process that is causing your choppy playback.If the offending process isn't essential (i.e. anti-virus), then click on said process and then click the "End Process" button.

Hope this helps.
