Hi all,
switched to 9.5 the other week, and started a short film scoring / mixing project.
I was given a 13 minute mp4 , 1080p with 10 mbit/s bitrate. Pretty average stuff you’d think.
The project now has about 12 mono and 2 stereo audio tracks in 48khz in AIF format, and scolling or start/stopping in the project has the video stuttering od restarting slowly, to the point where it’s sometimes hard to know if you’re actually precisely on a frame or cut.
I’ve worked with way heavier and longer video files in Cubase 7 or even 5 and never experienced this problem with the video engine.
My PC is a video editing machine btw and its performance should not be the issue.
Is there a particular reason for this related to the new video engine in C9.5? Any known solution?
It might flow better if you crunch the video down to say 1280x720 at perhaps 4 mbits. The free DaVinci Resolve can do it just fine. I did a short film with Elements 9.5 with a 720 workprint, using an old i7-960 processor. Image flowed like water at all times. Looked great on the screen, no aesthetic compromises from poor image quality. Some formats definitely work better than others, I tested a few different ones and there were notable differences that didn’t directly relate to size, can’t remember the details but at 720 just about anything will work.
The bitrate is usually a more problematic factor that the actual pixel size, but you 're probaly be right that downgrading it to below 6mb/s might help.
I’d be surprised if the prores 422 actually ran better that a much lighter mp4, espacially on a PC, ( and the engine is now apparently not quicktime based anymore ) but you seem to have good results with it.
