Everything should function properly, but you may have connection, voice chat or other issues. Type 3 - Connected through a router without open ports or DMZ setup for PS3. Type 2 - Connected through a router properly. Type 1 - Connected directly to the internet (no router/firewall).
#ISSUE USING RUNNING Q DIR PS3#
The PS3 offers Type 3, Type 2 and Type 1 NAT results. so that it can be edited and have transitions applied to it.Having a closed or limited NAT on your gaming console will cause a variety of issues. That's because all the info of every frame is finally present in its entirety. When the compressed "descriptive" material has been decompressed into individual, unique, editable frames, it takes up
H.264 is just one form of that compression. Those AVCHD frames only exist once all the comparisons and descriptions have been made and examined, and then real, individual, editable, complete frames can be rebuilt from the compressed descriptions.
It's as if you heard me saying "same as before, but one less apple" or "same as before, but with one more orange". They can't be edited in a computer till the incoming stream of data has been examined for each first-in-groupĬomplete frame, and then the descriptions of differences have been compared with the preceding descriptions and all those intermediate frames have been rebuilt. they must be rebuilt from their 'parent' frame. TheyĪppear to be present, but, in a way, they're "imaginary". The intermediate frames are not directly editable because although theyĪppear to be complete, when you play the video, they have no independent existence from the initial (.complete.) picture that's at the head of each Group Of Pictures. whereas iMovie has to do a similar job with software, which is much slower and can be more complex. The hardware micro-processor in the camcorder "decompresses" and rebuilds the non-existent intermediate frames, in real time, when you replay the video, and presents them on your monitor or viewfinder. That's the 'compression' method which AVCHD and HDV use to squeeze lots of data into a narrow 'bandwidth' or small amount of storage. on tape, camcorder hard disc, or on memory chips. So a lot of data can be packed into a small space. It's like instead of laboriously painting fifteen pictures of fruit in a basket (.with some pictures having three apples and three oranges, and some having more or fewer.) I paint just ONE picture, and then describe the next few by just saying "same as before, but one less apple" or "same as before, but with one more orange".ĭescriptions of how one frame differs from the previous one(s) take up far less space, or data, than having to describeĮvery frame in complete detail. That means that you can't accurately describe any of those subsequent fourteen frames unless you initially examine the FIRST frame of the group, and then "rebuild" each of the following frames by reconstructing them from the differences between that first frame and each of the others. or the current frame and the one before it. The following "frames" of video after that one aren't really frames at all they're just descriptions of theĭifferences between that first frame and the next frame. in HDV it's the FIRST of every fifteen frames. One of that group is a complete frame of video. as Winston and David said, it's stored on tape (.or on the camcorder's hard disc or memory device.) as a I'll try to make this simple: AVCHD is rather like HDV hi-definition video. ".If someone has a technical reason why h264 cannot be frame accurate edited I would be interested to hear it bearing in mind that it must logically be frame accurate displayable." If someone has a technical reason why h264 cannot be frame accurate edited I would be interested to hear it bearing in mind that it must logically be frame accurate displayable. This is a logical conclusion not a technical one. If it can be displayed frame accurately it can be edited frame accurate. I ask : can it be display frame accurately. Now someone might suggest that h264 cannot be edited frame accurately. So the question remains, Why is there a problem utilising AVCHD video and audio data? The only issue I see is that the transport stream need be converted to a program stream which involved organising the data in proper sequence. The file format is mpeg-2 transport stream also a standard. The spec states that is uses ac3 audio codec aslo a standard. The avchd spec states that it uses h264 video codec a standard. So why does imaove convert instead of using it directly ?
The very same as used my apple for itunes, apple tv, etc. It seems strange to me that imovie has to convert the avchd format into the bloated format it does.Īccording to the AVCHD spec the video codec is h264.
