I have a simple way to get rid of annoying audio. There are two ways that I can do it. My keyboard is a Microsoft Sidewinder, and it has both audio and video control keys. If I wish to mute the system’s audio, I press the mute key on the keyboard. The same key turns it back on when I want to hear the sound. The other way is via headphones. Lots of times when I want to hear the sound, I use headphones which are plugged into the headphone jack of the computer. On my system, plugging in the headphones causes the speakers to be muted while the headphones are still live. This lets me hear the audio while my family is sleeping, and, if I don’t want to hear it, I do not use the headphones. Either way is simple, and works every time. 😉

Good points. That is why I was stressing that he needs to use the aspect ratio of the format that he is rendering to. I did not want to leave the impression that everything has the same pixel aspect ratio. I did want to suggest that, once you figure out and confirm what you need in Photoshop to match the pixel aspect ratio for the desired render format, things become a LOT simpler.

I don’t see one. Double clicking inserts it in a new track on the timeline.

For a 720 x 480, which was my example, the png width should be any multiple of 655. The length can be as large as you want it to be. Then, as John pointed out, in pan/crop you set it to match the output aspect. It will then not be distorted when it is displayed. The factor which tells you what the png width should be is the pixel aspect ratio. For a 720×480 NTSC image that ratio is .909, so .909 times 720 gives you a width of 655. You simply have to determine what the aspect ratio is for the video file you will be rendering.
The reason for this is that pngs use square pixels which are a bit larger than the pixels used in video. Thus, the image is a bit wider for the same number of pixels.

What are the dimensions of the png file, and what are the dimensions of the rendered file? For example, if the mpeg2 file is 720 x 480, the png file must be 655 x 480. This is due to a difference in pixel shape for a png image.

Actually, I am thinking that a high bit rate is available for use with the 30p to increase its quality above and beyond the 60p image. There are substantially lower bit rates available for the 30p, but there is only one bit rate for the 60p. I’m thinking of dropping my frame rate down to get the highest quality 30p image since it may exceed the quality of the 60p. So….I’m thinking that Canon is not wasting space at all. Canon may see the 60p as an action shot that, ironically, does not require as much clarity as other types of shots.

I’m sorry, but I have always heeded the warning to not install K-Lite. Thus, I have no experience with how to use it. Perhaps someone else can chime in at this point to explain what, if any, problems may result from installing a codec package? Perhaps the simplest remedial step is to uninstall Vegas and Sound Forge, and then reinstall both. That will give them some opportunity to reestablish their codecs.

I don’t know the answer to your question because I do not use a hot key to make this kind of change. Instead, I have snapping enabled. This helps me in two ways. I can position the cursor on the time line to the beginning of an event and be sure that the cursor is precisely positioned. Then, I can simply drag the event up or down for as many tracks as I need, and the event will snap into place at the cursor location.

The processor looks good to me, but the memory is a bit small and one hard drive is very problematic. I’m guessing this is win 64 of some variety? Most recommendations that I have seen suggest a minimum of 16GB of memory. Also, at a minimum, I think Windows and your programs should be on one drive, and data like video should be on a second drive. That cuts disk contention (or thrashing) a lot. Personally, I prefer at least three drives with Windows on a SSD, and most of the programs on a separate hard drive with a third drive for data like video and audio.

When I said that, I was thinking of the statement that you made in this thread, which sounded quite reasonable by the way, that 60fps is a total waste of disk space when 30fps will do just as well. While I understand that bit rates can change things, perhaps you misspoke a bit about 60fps consuming a lot more space than 30fps? Perhaps it should have been qualified by; all other things remaining equal. As I thought about it, I thought perhaps the 60i for the one camera consumes just about as much space as 60p for the other camera. As it is, the Canon shows that 60fps will be recorded at 28mbps while 30fps will be recorded at 24mbps if the maximum bit rate for 30fps is used. Again, not a lot of difference. I am still struggling to deepen my understanding of this camera, and I think that is a good thing.
