MOV files you might be having some other wierdness as the stuff get's passed back and forth between Quicktime and Vegas, I suppose. Your description sounds like a throughput issue rather than a CPU issue, but you ought to have enough throughput to play a Sony YUV file. The second render was an uncompressed AVI which totaled 973 MB, close to 200 MB /sec, which sounds like it's close to your limit. Given what you're saying you ought to be able to handle that. Using the Sony YUV codec I get a 487 MB AVI file-nearly 100 MB/s. I just rendered a couple of 5 second test files (noise textures) at 1080-24p.
Realtimes trimmer not working 480p#
Setting the 480p project aside for the moment, how do you tell if Windows Media Player is playing things at full frame rate? These low framerates are the case when I set the preview to "draft" and 8-bit color rendering with no effects present. Why would I only be getting 18fps for uncompressed SD when the file type matches the project settings and no external monitor is enabled. I can't get 480p to play back in real time at full 640x480 even though I have plenty of ram left, 90% of my processor time is available and my RAID could problem play 10 SD streams concurrently without hiccuping. In fact, the problem seems to go deeper than 1080p. I can get 23.976 fps if I set the preview to "auto" but that resolution is too low for me to make editing decisions based on picture quality.ĮDIT - the bug below was fixed with a reboot. I can play back realtime no problem using windows media player. What perplexes me is that my processor use is not saturated and my RAID is way more than sufficient yet I am unable to playback the footage in real-time in Vegas.
Realtimes trimmer not working 1080p#
I do not want a low quality preview, I want 1080p online.
The memory is my chief suspect, but in order to get any more than 3 GB I have to upgrade my OS which is a major hassle.Īny ideas besides compression? I do not want to offline my files. My preview is done on a secondary monitor using the Quadro video card.Īs I said, the processor is nowhere near maxed out as it's uncompressed YUV 23.976 progressive footage. I do not want to RAM preview the footage, I want to simply edit at least one 1080p stream in Vegas in real time instead of framerates ~17fps. I cannot determine my bottleneck as my processors have plenty of headroom (only using 30% during playback) and my RAID has plenty of headroom (>300MBps). I can view that same footage in real-time by playing back the file with windows media player, but Vegas can't offer the same performance. I am using Vegas 8 Pro and am unable to view my 1080p 24p footage in real-time.
