Nesting and proxies

mortytemps wrote on 9/29/2020, 6:30 AM

Hi all

I've just upgraded to VP18 and using nesting for the first time.

When I nest a timeline that includes audio it takes a very long time to build a video proxy which it does automatically. A 6 minute nested timeline takes close to an hour to build the proxy for. When I render the audio in the parent timeline, it would only take 30 seconds or so.

Is this just something I'm stuck with, or is there a solution to make it work? It means the use of nesting for my purposes doesn't really work.

I'm running Windows 10, i7-8750H CPU @ 2.2GhZ, 16GB RAM, with Nvidia GeForce GTX 1050 Ti GPU. I don't usually have this type of problem with video processing.

Any help would be great!

Just to give you a comparison, I am using nesting for my dashcam footage which creates a file every minute. Unworkable in a regular project. I create a nested project to collapse that into a single event. The proxy is incredibly fast to create, within a minute per hour of footage, h264 with AAC audio.

Do you mean at creating or opening of that nested timeline veg?

Creating. Opening is instant.

@Illusion I was asking the OP @mortytemps

It happens whenever I create a nested timeline, or make some changes to the nested timeline (such as clipping the nested timeline, but not when applying fade outs)

When I create the nested timeline, I have discovered that if I can click 'Cancel' on the bottom left hand corner (where it says it is building the proxies). If I do this, I dialog box appears with 'Rendering' which does the process incredibly quickly. Within the folder it has built an .sfk file, instead of the timeconsuming .sfap0 and .sfvp0 files.

When this happens, the nested timeline can be previewed and there isn't any real issues. I can see the audio wave form as well.

However, if I then close that file, and reopen it, I can no longer see the waveform, and it just reads 'Peaks Not Available' - presumably it is not longer reading the .sfk file (but for some reason, it does when it is built the first time....)

Any suggestions?

VEGAS needs .sfap0 files (audio proxy) to create waveforms (.sfk files) for nested projects.

If you don't need video proxies (.sfvp0 files), try to turn them off in the Internal options.

Thanks altarvic

This solution did seem to work (for those looking for a solution: going into internal options, then searching for proxy and changing the value of the Create Video Proxies from 2 to 0). I'll suspect I'll just need to toggle this when I do actually require a video proxy to be created.

Bizarrely there does seem to still be a bug of some description. VEGAS doesn't seem to y need the .sfap0 file to create waveform in the first instance (when you first import a project into the timeline). It is only after you close the project and re-open it that it seems to require the .sfap0 file to display the waveform.

Unfortunately I've encountered another bug - despite the fact that video proxies are turned off in the Internal options, when creating or loading a nested project, it will still attempt to create a video proxy.

Has anyone else encountered this or have a solution? It is making nested timelines featuring some video formats unworkable.

It is "a kind of" proxy, needed to show and play that project on only 1 track.

@mortytemps, have a look at this: https://www.vegascreativesoftware.info/us/forum/proxy-creation-slowness--124517/#ca774974

Do you have previous version of Vegas installed?

Hi Illusion - thanks for that suggestion - I'll see if that helps!
