March 24, 2012 at 7:26 am in reply to: Convert 4:2:0 video to 4:2:2 mpeg2 video in conjunction with Sony Vegas-possible?I had read somewhere (of course I’m unable to remember where) that Sony Vegas does import to a better color space. However if you simply render this out it will make no difference, you have what you have from the camera. On the other hand if you color correct or grade that video then you may well be adding colors that were not there in the original.
It made sense to me that that vegas could do this

On some course notes I read recently they pointed out that even if you could win a claim of fair use at a trial of copyright violation; could you afford to find out? Should someone want to make a skape goat of you it would take considerable time and expense to defend.
YouTube does seem to have some sort of royalty system in place. Producer Pete Waterman gave an interview a year or two back where he complained about how lttle he was getting.
What seems to be missing is a way for the average youtuber to pay royalties apropriate to the views they receive.

thanks very much, things are much smoother now. I was convinced transitions needed two adjacent clips.

Hi, I think I can see the problem. It is easier to spot on the HD setting (youtube) and using full screen. You can often see one frame and then the next is superimposed albeit semi-transaparent. When he pans past thin vertical lines they seem to split in two.
What is the original footage? Did you create the project by using the button to match settings to media? What does vegas think it is?
It is more difficult for the low end cameras to keep up with a pan and very diffcult when you are moving in all directions (e.g. walking thru the woods).
Footage is usally interlaced (e.g. f you have a 50 line system it wll scan half the lines on one scan and the other half on the other) More recently cameras can scan the whole frame in one (aka progressive). If your footage is interlaced I think you can render as progressive in Vegas and it must interpolate the missing lines. However if the camera is moved it becomes difficult to do this and you get two images superimposed. -
Craig, my suggestion is only going to help if Vegas comes up, stays up but will do nothing. You seem to have something much more serious.
Are you just starting it up? or do you first try to look at some media?

Hi, what do you mean by hangs? is it that Vegas blows up and gives errors? or does it just sit there not doing anything and won’t respond to any commands? For the latter, go to: Options, PReferences, Audio Device and make sure you have a valid setting. A long shot but my Vegas (Pro 10d) hangs if there is a diconnected audio configured.
I have an HP 64-bit W7 system with 64 bit Vegas Pro 10e installed and that works lke a charm.

Hi, apparently this is a well known problem. See this discusson (https://social.technet.microsoft.com/Forums/en-US/w7itprohardware/thread/65cb7a25-2a84-4875-aa27-b084537e8da1/) which explains or gives a pointer to the details of why. For some people reverting to the Legacy Driver solves their problem, that note explains how to do it. You will have to make your own decision as to whether the fix will work for you.
I had a similar problem but was reluctant to do it (revert) because on my Sony camcorders I can aquire without problems. My issue was resolved by new software from the vendor (for another device).

Mike, in this case the animation is a Wpf/SilverLight animation that is stopped 24 times a second and a “snapshot” is taken and written to the png file. Each snapshot is then “appended” to the avi file (using an api). It would be the easiest thing to keep every frame and name them in some way that gives the order.
what would be the workflow to add them to the timeline?
thanks

thanks Bob and Stephen, alas I’ve misled you slightly. The png files are created on-the-fly, saved to a png fle, added to the AVI file as a frame and then thrown away. It is an animation. So for 15 secs at 24 fps, that’s quite a lot to add as pictures to the timeline.

I’ve made some progress on this. I added some extra FW ports on the laptop via a pcmcia card (I’m not convnced this helped but it may have). I switched the FW connection in the back of the box (again I dont think it helped). Mainly I noticed a new Unversal Control download on the PreSonus web page (that says it has Windows 7 support). I installed that and suddenly everything worked. So I think the moral of the story is ignore the CD that comes with the device and just get the latest from the Web. Vegas now accepts audio from the device.
I mentioned previously I had read about a “loss of synch” this device gets periodically; I don’t think that was what I had. That was probably just driver incompatibility that was resolved by the new driver.
However the device did disconnect for no good reason once after it was “working” and I think that is the “loss of synch” people refer to. But it does offer me better pre-amps than my old device and I’m looking forward to using it 🙂
