Unfortunately, we are still trying to determine what factors may be contributing most to your problem. Mar 31, AM. Doubt it would be a codec configuration issue per se. On the other hand, this may indicate a data handling issues. QT 7 would normally be better at handling legacy compression format program streams while QT X is designed of more modern formats in either program or transport streams.

Would normally assume the files are probably H. These files are the most common and are usually very stable unless pushed to upper data throughput limits forcing the QT player to drop an excessive number of frames during playback which, in turn, can lead to choppy or frozen playback.

Providing specific codec information may or may not provide further insight into your issues. However, I did not see any indication that you checked the Activity Monitor to see if any apps or processes are "Not Responding" on the problem platform. This is what I would normally check once you determine this issue is not related to USB connectivity. Thanks again for your reply. I am a bit of a novice when it comes to checking what you initially asked. Looking at one of the files, this is the information I have got:.

Hope that information this the sort of thing you are asking me. This video in particular was recorded on my Nikon D but I also have GoPro videos that do the same thing.

This may or may not be more than your system can easily handle. To see how well your player is taking the load, open the same file in your QT 7 player and compare the playback frame rate of the file with its encoded frame frame rate. If the player is dropping a significant number of frames, this could be the main source of your problem and different players handle data overloads differently.

I see in your case that you are viewing the x file at a resolution of only x Unfortunately, making the display smaller doesn't affect the amount of data processed per unit of time. In fact, it actually adds to the problem since the data has to be fractionally scaled for final player display. I would normally transcode the file to the target display dimensions I want to use for distribution using a much lower data rate.

For example, I am currently testing p xp24 H. Your file is what I would normally keep as the raw archival file used as the source for edited distribution content at lower data rates more compatible with older systems and devices in general use. Seagate is a drive OEM. The drives can be used with interfaces ranging from USB 1 to Thunderbolt 3. Knowing which specific interface is being used would give us a better idea as to the data transfer capabilities of your drive and whether or not it might be a contributing factor to your issue.

Look for any app or process names that appear in red any time an app seems to freeze up or seems to be having a problem during use.

In some cases the issue is easily found—e. This doesn't normally happen very often but is a good place to check when strange things happen but the Finder doesn't appear to be having any obvious problems. Depending on the model and settings, your GoPro files could have even higher data rate issues—i.

Play the same file with MPlayer or anything else and it's perfectly smooth. Where's Apple? I tried the setting change suggested by Spaztik and it works great. The choppiness is all gone.
