There is something wrong with my Corel Video Studio x4 settings or with my hardware configuration. There has to be some kind of bottleneck that would explain this distressing rate for for rendering a video of 10+ minutes in length. I tested 3 videos and clocked in their time to render with a stopwatch because Corel Video Studio x4 Pro doesn't provide one to keep track. Someone must have an answer for this. I used the MPEG-4 HD template which is 1920x1080 with a 15MBit rate. Test 1 - 1.00.06 - Took 1.37.22 That's a 1 minute video taking 1 minute and 37 seconds to render. As it renders you can't count the frames while processing. Test 2 - 5.00.06 - Took 7.35.97 That's a 5 minute video taking 7 minutes and 36 seconds to render. Its in line with Test 1 in rendering relatively fast. Test 3 - 10.00.07 - Took 1.30.00.00 That's a 10 minute video taking nearly 1 hour and 30 minutes to render. You can count the FPS as it renders most of the time. Test 1 - avi was 124 MB - Rendered mp4 was 97.7 MB Test 2 - avi was 606 MB - Rendered mp4 was 487 MB Test 3 - avi was 1.2 GB - Rendered mp4 was 974 MB With test 3 I practically fell asleep. It took well over 1 hour and since the finished video woke me up, after checking the watch it was about 1 and a half hours. Test 3s time to render is unacceptable in comparison to Test 2. Test 3 should've been less than 20 minutes, but instead it dragged on for about an hour more than that. The videos I was rendering were done using Dxtory with an x264 codec named x264vfw.2273kMod.x86. It records compressed avi files that are much smaller than the Lagarith Lossless or Dxotry Codec. The big question is why is it taking so much longer to do a 10 minute video compared to a 5 minute one? According to resource monitor I'm not running out of ram. I always have more than 1/2 my ram at standby or free. The i5-2500k CPU is pretty much in full swing during the renders, however doesn't stay as consistently between 90-100% load when doing the 10 minute video. I'm doing most of this work on a Western Digital 3TB Caviar Green drive, which isn't that fast, but considering how the 5 minute video rendered at a good pace, why would the hard drive explain the 10 minute video being so slow? I tried moving the work files to my SSD, granted which is my OS drive, but I'm getting the same results. What's going on here? What can I do next to solve this problem? -------------------------------------------------------------------- 5 MINUTE VIDEO SOURCE INFO General Complete name : F:\Video\Video Projects\Dxtory Recordings\BatmanOrigins 2014-07-21 01-00-31-521.avi Format : AVI Format/Info : Audio Video Interleave File size : 606 MiB Duration : 5mn 0s Overall bit rate : 16.9 Mbps Original source form/Distributed by : Video:x264vfw -

The comparison lacks essential details from the source videos.
Media info: unavailable due to missing source data.
Encode log: no output (no video processed).
Thank you for your reply. I think I can retrieve the media details from the source and the result videos. To obtain the encoded log, I would need to rerun the test. I'll share the media information next.
I right click on my videos and immediately see a Media Info option. It displays the version as MediaInto v0.7.69. I shared the saved text file details for my 5 and 10 minute source and result videos in my original post. I have a x264.stats file, but I’m unsure how to open it correctly or what actions to take with it. If I try to view it in Notepad, the information is too extensive and causes the tab to crash.
I've observed that after rendering a video, an icon appears in the toolbar tray named "LAN Video Decoder" and then vanishes. I found it in the folder: C:\ProgramData\Microsoft\Windows\Start Menu\Programs\K-Lite Codec Pack\Configuration. This situation is confusing because Media Player Classic is linked through the K-Lite Codec Pack, yet it keeps triggering the LAN VIDEO DECODER uncontrollably. I'm unsure why this occurs or how to resolve it. The only solution I see is removing the K-Lite Codec Pack, but that would also remove Media Player Classic. It seems I didn't agree to have K-Lite interfere with my video editing software. There was a lot of misleading information during installation, and I never intended for this to happen. It's impossible for K-Lite to be necessary for creating videos.
I noticed something interesting during my tests. Remember when the 1 minute and 5 minute clips loaded so quickly? I created a project using a 5 minute recording plus a 7 minute one, both rendering independently—yet the combined 12 minute version processed just as fast. A 12 minute file took only 18 minutes and 12 seconds to render. This shows a big boost. The key seems to be video length itself. Longer recordings slow down processing even if they load quickly. I’m unsure what settings work best for the x264vfw codec, but it’s clear that longer files cause issues. I’ve managed to record a 7 minute clip on a 3TB WD Green Drive with a 63MB/sec write speed. Whether it’s a 7 minute or a 20 minute clip, maintaining 30 fps at 1920x1080 is possible. The bottleneck appears after 10 minutes—beyond that processing becomes sluggish, like trying to edit in slow motion. I recorded a 10 minute and 33 second clip onto my OS drive SSD, which took 16 minutes and 35 seconds. That’s reasonable, not taking an hour. Using the same method for a 21 minute video caused delays. Short clips are fast; long ones feel heavy.
I visited the site and saved the executable for Mediainfo. During installation, an adware/malware warning appeared using OCSetupHlp.dll and Open Candy. It’s not present anywhere on my PC, even in temporary folders or via file searches. AVG and Malwarebytes couldn’t locate it either. I found a link to OpenCandy here: http://www.avgthreatlabs.com/virus-and-m...I=0&BE=265. I read some details but ignored the alert. When I tried to install, no toolbar options appeared, so nothing was checked off. After completion, there’s no new app in the start menu and no option to view details after right-clicking a video. The next folder I saw is C:\Program Files\MediaInfo.dll. What should I do to access it?
