June 7, 2015 at 10:44 pm in reply to: Diagnostic of possible bottleneck, very slow renderingThere have been many comments on the forum that the Kepler (i.e. K600) is not well supported for renders in Vegas. Similarly, there have been many comments about inconsistent support for gpu processing. Thus, the comment that you would be much better off by rendering without gpu support, and rely solely on the cpu.

Try disabling resample. That may give you what you want which is 25i.

I know this is not what you are asking, but why are you using the trimmer? I use the trimmer only for a quick view of a video to determine if it is one that I should keep. Otherwise, I use tools like split on the timeline to handle the “trimming” of an event. That handles all of my needs quite nicely without involving the trimmer, and a slightly different approach to managing my videos.

I do not know what it is supposed to do. So far, I ignore it and things continue to work as they always have.

These days, Vegas Pro comes with DVD Architect included. The directory you are looking for is created by DVD Architect when it prepares the files needed to create and burn a DVD. Vegas creates various types of video and audio files that can be used directly for playing on a PC, uploading to Youtube, or by programs like DVD Architect which creates DVDs of various kinds. Vegas may, for example, place the video in an mpeg-2 file, and the audio in an AC3 file. DVD Architect then uses these two files to build a DVD. Part of that building process is creating the VIDEO_TS directory. The ability of Vegas to burn a DVD is probably a holdover from its earlier days, and is probably not used very much since it is a very limited function.

One of the standard bits of advice for Dolby is to set “Dialogue normalization” at -31db to keep audio levels up. However, it looks like you need the Pro version to do that. The Studio version does not allow you to adjust the settings in the template. That would be a deal breaker for me.

The best advice is to tell your boss that CDs are intended for music. They do not work well for video. Video requires at least a 4.8GB DVD. Then you can explain to your boss that it takes either a lot of compression or a lot of editing to fit 23GB of data on a 4.8GB disk. Lots of compression means a very poor picture which will be a big disappointment. Lots of editing means cutting out a lot of material which may also be a disappointment. One option is using a double sided DVD, which will store roughly 10GB. Twice as much storage space will reduce the pain of compression and editing. The third option is a Blu-Ray disk which can hold all the material, but is more expensive and requires a Blu-Ray player.

If you render to a wav format, you will get only audio. If you render to an mpeg 2 format using the DVD Architect NTSC Video Stream template, you will get only video. However, if you render to an mpeg 2 format using the Program Stream NTSC template, you will get both video and audio. So, what avi or mp4 template are you using for your render?

I struggled with this problem long ago. My difficulty was finding the dimensions of a png image file which would not cause letter boxing. There is probably a way to calculate this, but I have not yet found, or perhaps understood, it. I determined by trial and error that a size of 655 pixels x 480 pixels will display full screen on an NTSC video, which is 720 x 480, and not cause letter boxing. Thus, for still images, I always use a size which is a multiple of 655 x 480 such as 1310 x 960 which has twice as much resolution.
A second method, is to use pan/crop on all video events on the time line. Right click within the pan/crop screen, and click on “Match Output Aspect”. This will crop images which are too large, or expand and crop images which are too small. This avoids stretching the image to fill the screen, and gives you control over what is cropped out of an image which does not quite fit.

Sorry, but I didn’t notice your switch from ac3 to aac, and I’m not into Apple. I’m afraid I can’t help.
