When I record a video using my Nikon Coolpix s4000, when I try to play it back the sound plays at normal speed but the picture is in slow motion! This happens everytime I record a video, is there anything I can do? Many Thanks

Look for a Menu then FPS (Frames per second) option.30 fps should solve your issue. sometimes in order to keep file size low the setting is slower causing this issue.Good Luck.

I just got my Xacti CS1 and after I shot a couple of test videos, I checked the playback. On the camera screen, playback is flawless, it's quite great, however, when I play the videos back on my macbook in quicktime player, the video is choppy. It will skip a couple of frames every second. It just freezes and then all of a sudden it's a completely different frame like the video was cut and spliced together. What's wrong?


p.60 of the manual describes different recording modes with lower resolutions (1280x720) pixels and lower frames per second (30fps).

I would choose from the menu to record in a lower resolution and lower fps mode so that the quicktime program can display the video at a good rate for you.

I don't know what kind of macbook you have, but usually such problems are due to the older macs not having enough speed to display high definition video with all its data all at once.

I used to have problems a few years ago, before i upgraded my hardware on PC's, with choppy video that was High Definition.

I converted an MP4 file to AVI and when i play the movie on quicktime the audio is out of sync and the movie plays like its on fast forward. i am trying to upload it on youtube and when i put it on youtube as an mp4, the audio was all out of sync i just want to get the damn thing on youtube!!!!


Give this a try:

Download the latest version of AVI audio sync tool: YAAI_2.0.3.488.zip
from http://findfiles.com/list.php?string=YAAI_2.0.3.488.zip&db=Mirrors&match=All&search=

First of all, make a backup copy of your avi file (this is very important!).

Step 1. Unzip YAAI_2.0.3.488.zip file. Launch YAAI.exe , "Open AVI" dialog will appear.

Step 2. Find and open your AVI file.

Step 3. Click on "Sync Audio" tab. Small video player will pop up.

Step 4. Now, adjust audio delay or frame rate (FPS) using sliders or appropriate buttons.

Click Apply. Video player will start playing your file with changed settings automatically. You can adjust and apply these parameters several times to pick up necessary values for audio delay or FPS. So, try to experiment and to set appropriate audio delay or to change FPS (frames per second) settings for your avi file.

Step 5. Finally, close YAAI tool. When it asks the question: "Do you want to keep the changes?", click Yes.

Hope this helps.
