Nested .veg file rendering issues

CJB wrote on 10/25/2014, 4:13 PM
I have read the history on some of these issues but thought I'd post my particular problem since it is not a format issue like prior problems.

When I first open a .veg with nesting it seems to do some kind of processing for the nested .veg files. (likely creating sfap0 files). However based on the setting I used for "preview quality" in the preview window, the imbedded .veg file will be rendered per that setting (i.e. draft, etc). If I go to render the file to Blu ray or other format the output of the .veg will be in that setting. It does not matter what I change the preview quality to later, unless I somehow get the parent .veg to re-prerender the nested .veg while the preview quality is set to best - full. Is there any way to force this re-rendering or get the rendering output to rerender even the .veg? It is very easy to note on a Newblue Titler pro 3 title that is in the nested .veg

thanks,
c

The preview has nothing to do with the render, and the nested .veg files 'render as' to whatever your current project properties and 'render as' template are set to, just like any source media on the same timeline. There is no re-rendering. Are the project properties of the embedded veg file the same as your master project?

I haven't used nested VEG files for awhile because I used to get strange field issues when using interlaced footage. However, from memory, I think the only things which determines how the VEG file you drop on the timeline looks are the project settings in the VEG file. There is nothing in the "render as" templates which affect how the source media (i.e., the media in the VEG file) are displayed in the project. I think this is what you were saying.

When you then render the project which includes these VEG "video files," those "render as" settings will obviously affect the output.

I only posted because it sounded like you were saying that there are "render as" settings in the video coming across via the VEG file, and I don't think that is the case. I'm pretty sure you didn't mean that.

The problem is with "preview quality", not "render as" templates.

Looks like it may be a Titler Pro 3 problem. I did this little experiment where I took a media generator clip with a simple default title using TP3 and a different one using Sony Titles & Text. Set the preview quality to "draft - full" and saved that to a veg file. I then imported that to a .veg file as a nested event and rendered to mxf. The text for TP3 came out looking like the "draft" preview, i.e with low res jagged edges. The Sony title looked sharp as a tack......

Reset the Video Preview "preview quality" setting to "best-full" rendered perfect.

it is odd, but good to know.

John, for the record, I think you are referring to the problem whereby if you downscaled nested interlaced footage to less than 50% of its height (number of lines), rendered output would be incorrectly progressive. I have verified that that problem is fixed in VP12.0 (Build 770) and VP13.0 (Build 373).
