Howdy Guys, hopefully this is the correct place for this.
First off, I'm a noob when it comes to this stuff. I've been using Hitfilm 4 Express to edit little clips to share with friends and such, and at 640 and 720 it edits them well other than some choppiness for the first couple seconds after dragging the timeline slider. However, when editing 1080 it's fairly choppy even without any effects, and just a single track. Changing the playback quality to quarter/half/full/antialiased doesn't make much difference, though full/antialiased seems to play back the smoothest. I was running a GT 630, but read that hitfilm was GPU intensive and that Nvidia ruled the openGL world so I picked up an old GTX 660.
The specs for my current rig are:
CPU: AMD A8 6600K OC'ed @ 4.7Ghz
GPU: EVGA GTX 660 SC 2GB OC'ed
Here's a link to the rest of the build and they're benchmarks: http://www.userbenchmark.com/UserRun/2862592
Here's a video I made showing the chopiness, it may be slightly worse while recording the screen, but not by much if any.
And here's a datalog I recorded while making that video.
If there is some other data you'd like, let me know, on the begining of the above video, it shows HWmonitor which displays all the things I datalogged.
It would appear the GPU is barely idling, while the CPU is ranging between 60-70% usage on all the cores. Typically it does run between 55-65% while not recording the screen. I wouldn't be suprised if I'm limited by the CPU, but I don't know why it would only be showing 60% usage.
Here is the video format I'm editing.
And the Audio
Would you guys consider this normal? Is there something I can do to help improve the playback quality in hitfilm? I've read about converting the file formats, but I'm hoping not to mess with that as it would take quite a while to convert the 10GB of video file every time.
Thanks a bunch guys! Any question just ask!
