    The Discussion

      Great show guys (as always). Here is a little question for you - why do the encoded video sizes differ so greatly on here. The Mid wmv is 90Mb but the High wmv is weighing in at over 1.5Gb. Now of course the mid is a much smaller frame size (512x288) and the high is usually a 1280x720 but they normally are around the 300-400Mb mark. This is not the first time I have seen such coding variations on Channel 9 but what better forum to ask than in Defrag's own comments. The answer of course is the way it was encoded but obviously someone is doing this and must see the massive size difference in certain cases. For most you need the High version to be able to see a lot of the text clearly enough, so it is not just cosmetic to want the larger size video. thanks for your time

      @JockStrap: The high WMV is actually the 'source' video, and the size of that can change radically from one content creator to another. I honestly want the source to be as high as possible, since it is our master copy. Given that, perhaps we need to start making a high quality version separately instead of just giving people the original... something at a consistent bitrate/resolution (1280x720, 2.5Mbps for example?)

      also try if you can disable power saving options in device manager for the BR drive.

      Use this tool:

      USB Drive Letter Manager for Windows

      [21:19] - Is it safe to delete appdata/local/temp?

      no, don't delete the complete folder, especially the LOW folder. This breaks apps with low IL level.

      I've automated the diskcleanup with scheduled task:

      @JockStrap: This show was shot while Golnaz was on vacation so it was rendered by an external editor not using our Adobe Premiere present. We typically try to stay around 1GB/hr on our highest setting, this is obviously a good measure higher than that. Thanks

      @LarryLarsen: @Duncanma: Thanks guys that explains it and also really appreciate you making the original source available.

      However what is this using "Adobe Premier", come on guys "Microsoft Expression Encoder 4" FTW Angel

      @JockStrap: You might be making a joke, but all Channel 9's video encoding is done using Expression Encoder, but it isn't really a video editing application, so the original video is created using Premiere.

      @JockStrap: It depends on the show, whenever possible we try to just do shows using our Tricaster. There are some times when we use different components from the CS6 Suite.

      It is unlikely that any command-line program would help in that case (even though there seems to be one:

      What you would need to find out is what process prevents you from removing the drive. You could use Process Explorer to do that. Start Process Explorer, click Find -> Find Handle or DLL -> enter your USB stick drive letter (like G:) and click Search. This will list processes that reference the USB drive.

      Note that although it is possible to close a handle using Process Explorer ("freeing" the USB drive for Safe Removal) it is not recommended in most cases. It's better to simply exit the program that is using the drive.

      I have a question for the show: what are the most common reasons for the Easy Connect feature to be unavailable in Remote Assist?

      Gov's comment about needing a separate folders for 32-bit and 64-bit apps is specious. Since the CPU can execute both types of apps, and Windows will bring up WoW when a 32-bit app is run by looking in the .EXE header rather than the folder name "(x86)" there is no justifiable reason for the separation. Further, the determination of which folder is chosen is based upon whether the INSTALLER is a 32-bit or 64-bit app, not upon what is actually being installed.
