Dangerfreak Posted January 19 Share Posted January 19 I still have the old version 10.43 of videopad installed, because it's fast and stable (except for some minor bugs). That's why I use it for big projects. For small projects, I use various newer versions of videopad, e.g. v12.39 and all 13.x versions, so I can test them without any risks. Because I'm using various versions, I noticed a really big speed difference in building previews (=in the timeline, the green bar above the video clip, that builds up from the left to the right): Version 10.43 is way faster than all versions 12 or 13! To be sure I started a benchmark test, this is my test setup: 1. For versions 12 and 13, select any option in the menu Options->Advanced->GPU Video Processor. Restart videopad, so that changes can take effect (whatever you select, it's still slower than version 10.43). 2. Click "Clear Unused Cache Files" in the menu Options->Disk->Cache - just to be sure, that the cache can't affect the speed. 3. Put any video clip into the timeline (I tried several different resolutions, same result) 4. Add these three video effects (probably also works with another number or other effects), from top to bottom of the effect window: - Zoom: Aspect Ratio 1:1 (something that is different to the video clip), default Left/Top/Right/Bottom settings. - Temperature: Default value (64) - Saturation: Default value (25) 5. While setting up the effects, building preview already starts. To start the building over, I just set any keyframe in the effect window, then I started the stopwatch to get a precise result. 6. I waited until the green bar above the video clip (in the timeline) is complete. Then I stopped the watch. The results were very clear: Example 1: For a 31 second 4k clip, version 10.43 took only 1 minute and 32 seconds. Version 13.06 took between 2:50 and 3:50, depending on the GPU processor settings. That means, version 10.43 was about two times faster. Example 2: For a 44 second 1440x1080p clip, version 10.43 took only 32 seconds. Version 13.06 took between 1:18 and 2:04, depending on the GPU processor settings. Version 10.43 was about 2.5 times faster. These results sure depend on your hardware, I have quite an old notebook (Windows 10 64bit, Intel Core i7-4700MQ 2.4GHz, 16GB RAM, NVIDIA GeForce GT 740M + Intel HD Graphics 4600). Nevertheless it's obvious, that videopad versions 12 and 13 got slower. I wouldn't mention this, but while the preview is building up, I can't really continue working on my (big) project, everything is extremely slow, especially I can't play the preview and check the video, it's just hanging or stuttering until the building process has finished. Unfortunately this process starts from the beginning, if I set any keyframe in the effect window. Sometimes I want to zoom to a certain small section of the clip and follow it, so I have to set a lot of keyframes, if the section is moving inside the whole clip. That means, I have to wait very long - or use good old version 10.43... What are your experiences? Can you confirm my test results? Link to comment Share on other sites More sharing options...
