  1. Hi Rox ..., I second what Nat said above I don't know if VideoPad will use the video processor for rendering. Some rendering software will, which will greatly speed the process. Also more RAM will help. Reducing the output resolution will help greatly. Lastly, defragmenting the hard drive will help. Rendering reads large files, greats many temporary files and the final output is typically large. If the hard drive spends little time moving the head, the process goes faster. You also stated you OS was Windows 7. Windows 7 Did a poor job at memory management. That is another reason to kill tasks that are running, including browsers. Cheers, Mike
  2. The jerky playback which NationalSolo experiences is PC hardware related. Such jerky appearance is the result of periodic retrieval of data which has been cached to the harddrive. As I remember, Nationalsolo's computer is running a 32 bit OS with about 3.2 RAM and a standard hard drive. VLC requires little RAM. VideoPad requires a lot of RAM to playback smoothly. Manuel, last night I rendered a 55 minute AVI file outputting to a MP4 format file. I have viewed the MP4 output and found no video/audio synchronization problem. I have viewed sync problems in the past. I found dividing the video into short scenes before editing help reduce sync issues. Also editing those scenes separately helps improve VideoPads editing execution speed. Then after editing all the small scenes, load all the edited scenes into a final sequence for rendering. If you find this too cumbersome, do your editing on a desktop computer with a fast multicore processor, a multi drive RAID, a 64 bit operating system, and 8 Gb of RAM. Cheers, Mike
  3. I agree with Picbuck's response. Loading a 20 Minute video file takes a long time, the first time it is loaded. After saving the project file, VideoPad will reload that project within seconds. Using normal PCs for video editing, is a good exercise in patience development. It also will make you buy high performance computers on your next PC purchase. I suggest you read the webpage at the following URL which lists typical PC system requirements for video editing. https://www.videoguys.com/Guide/E/Videoguys+System+recommendations+for+Video+Editing/0x4aebb06ba071d2b6a2cd784ce243a6c6.aspx Cheers, Mike
  4. Hi Jeff, I believe your rendering difficulty is your low PC RAM and slow harddrive. I do not observe VideoPad rendering any slower than a competitor’s video editing program Pinnacle Video Studio Plus, which has been on the market for many years, and a favorite among hobbyists. The key to your problem is stated on the VideoGuys website (first URL below) in the paragraph containing “your main system requirement is: 9+ megs per second sustained throughput for real-time… For HD editing you will need even more!” I believe HD takes 4 time 9+ or about 40 megs per second. Harddrives move data about 10 time slower than RAM, so you can either install 8 Gig of RAM, and a 64 bit operating system such as Vista 64 or Windows 64, or run a SATA Raid drive with 4 physical drives or a solid state drive. If you are skeptical about what I am writing here, I suggest you read what the experts have to say on the subject. Read the webpages at the following URLs. https://www.videoguys.com/Guide/E/Videoguys+System+recommendations+for+Video+Editing/0x4aebb06ba071d2b6a2cd784ce243a6c6.aspx http://www.brighthub.com/multimedia/video/articles/87956.aspx The bottom line, video editing is the highest data rate application that I have ever done. I have not searched the NCH website fully, but I expect it does not warn the customer of the performance they should expect for various hardware configurations.
