I've discovered some problems with video support in the new Sonar 2015 Platinum, version 21.00.01 Build 253 x64, which I've reported to support but also want to describe here in the forum.
I'm a film composer and work a lot with video material in DAW. In X3 Producer I got not bigger problems with video.
I want to continue some of my X3 projects in the new Sonar version, but when I start playback Sonar freezes completely for many seconds until the playback starts.
I've done some tests and could evaluate this problems regarding the "Tim In-Time" property. The larger value I set for "Trim In-Time" as longer Sonar freezes on every playback start.
For example I've project with a video in wmv with dimension of 640x480 and 12 minutes long. When I set Trim-In-Time to a value of 5 minutes and press playback from project start, Sonar freezes and waits about 13 seconds. It goes faster as I move the start locator to the end of the project.
The same projects with same video loaded in Sonar X3 causes no problems, so it seems there must be something broken with video support in 2015 21.00.01.
I've tried different video formats, but always the same.
And that's not all. In X3 there was a "Render Quality" tab in the video properties on which I could set some properties for playback improvements like a Preview-Quality option. Also I could set an external DV-Output. In Sonar-2015 I miss all of them completely. I don't see the Render-Quality tab and no option for sync to an external output.
If this are bugs, then I hope Cakewalk will fix this very quickly.
