Proxy playback - please fix!

Hi Magix (hopefully you are following this forum)

When Vegas plays back a PROXY file (.sfvp0) it also seems to turn off anti-aliasing or scaling, or downsamples the clip again!

I use Vegasaur to create 1920x1080 XDCAM EX MPEG-2 Proxies as Vegas Compatible .sfvp0 files.

When these proxies are played by Vegas they look very blocky, but when the same proxy file is duplicated and renamed without the .sfvp0 extension and bought back into Vegas as a normal MP4 file then it looks MUCH MUCH better and is the perfect proxy. The very same files, bit for bit identical.

I am assuming that Vegas is disabling anti-aliasing or scaling of the proxy file, or else is downsampling it again, whenever it knows it's using a proxy with extension .sfvp0

PLEASE PLEASE sort this, as it is otherwise the perfect workflow.

I had a look in the INTERNALS tab, and I can see two options shown:

Video Proxy Renderer GUID and Video Proxy Render Template GUID

both of these have HEX code values so can't just be simply changed.

Why is Vegas lowering the proxy quality again? These proxy files play back perfectly at beautiful quality in Real Time in Best Full, but they are useless when handled by Vegas as proxies because it just makes them blocky.

The only temporary solution is to Replace Media and switch the Originals for the Proxies, and then change them back before rendering.

Please can this be fixed, or even add a simple tick box to not turn off anti-aliasing (or whatever) when handling the proxies.

Richard.

@altarvic: I would love to use your script in Vegas Pro 12 as I made the same observation richardbushell did: Proxy files could look better.

Unfortunately your links do no longer work (I guess after the switch to Magix, error message is "*** Link corrupt ***"). Is there any chance you could make your scripts public again?That would be really helpful!

I don't know what made the links "corrupted" here (they were always public), but I fixed them. Don't forget to change

using ScriptPortal.Vegas;

using Sony.Vegas;

if you want them to work in Vegas Pro 12

Tried this and proxy replaces full res clips on time line. However if you use fxmedia such as stabilise then this is not applied to clip when rendered as far as I can see?

Hello altarvic! Thnx for fixing the link problem! I downloaded the scripts, changed the "using Sony.Vegas" part but as soon as I call the scripts within Vegas Pro 12 I get the following error:

C:\Program Files\Sony\Vegas Pro 12.0\Script Menu\Add Proxies as Takes.cs(27) : Type- or Namespacename var could not be found. (Missing using-directive or Assembly link?)

(That's a translation of the error message because I have a german version installed!)

Unfortunately I'm no JS/C# programer, do you have any idea what's going wrong?

I believe, because of the old .NET Framework in Vegas 12.

I replaced incompatible code, you can re-download and try again.

Thnx for your quick reply. Yes, it's working now but a quick test with a large clip cuted into pieces and doing some zoom in (4k source material with default Vegas Pro proxy files) lead to wrong zooming and after switching back to original/original proxy, the IN and out OUT points also changed. Strange. But thnx anyway, I'll have a closer look at it with my next project.

Regards,
Rüdiger

These scripts were created for @richardbushell. Maybe his specific proxy workflow is not for everyone (and he uses Vegasaur to create custom .sfvp0 proxies).
