Nobody would like to spend too much time on video conversion. People want to finish their video conversion process in 2 minutes. To get a fast video transcoding process, you have to know which factors affect the video conversion speed. Generally speaking, your video output settings, your computer hardware apecs and performance, all of these have influence on video conversion speed.
Now, after you learned what affects the video coversion speed, we can increase the video transcoding speed from the each aspect: make your computer perform better and get a lower bitrate video.
Tip 1: Use NVIDIA CUDA Accelerate Video Conversion Speed
Video Converter using CPU and GPU acceleration technology can speedup video conversion process. Pavtube Video Converter takes full advantage of the NVIDIA CUDA technology and AMD ® Accelerated Parallel Processing (APP) to largely accelerate video encoding speed. The GPU acceleration saves users time when encoding video files to H.264 codec and H.265 codec. With a PC running on a CUDA-enabled Graphics card, the conversion speed of Pavtube Video Converter is about 30X faster than before. Meanwhile, more CPU resources are spared for other applications, that is to say, your computer will run much smoother and faster than ever before when you using Pavtube Video Converter to do format conversion. To read here to figure out if your computer has a CUDA-enabled GPU.
Simply click "File" > "Add Video/Audio" to load your movies. Then Choose "H.265 MP4 Video" or "H.264 HD MP4" in "Format" drop-down list. Now, move your cursor to "Tools" button on the top of the main interface to choose "Options". Then you can enable GPU Encode Acceleration.
Tip 2: Use More CPU Core to Convert Video Files
Video manipulation relies heavily on CPU. A high-performance processor can help you convert video faster. For example Intel Core 2 can process 4 data streams at a time and i7 can handle up to 8. In Pavtube Video Converter "Conversion Settings", you can use more CPU to computer graphics. You can set the value of CPU Core Number as all or customize core number to process video conversion.
Tip 3: Change Video Settings
In general, a higher bitrate will accommodate higher image quality and larger video size in the video output, which affects video conversion speed. In addition, setting other parameters lower such as lower resolution, lower frame rate, etc also can shorten video conversion time although it will reduce video quality. If you don't have high reqirement on image quality, you could try this way to increase video conversion speed.
What's more, keeping the same video codec when converting video formats also can reduce video conversion time. For example, when you can convert H.264 MP4 to MKV, you can get higher video conversion speed when keeping H.264 codec. On the contrary, if you transcode H.264 MKV to H.265 MP4, the conversion speed will be slow.
Tip 4: Batch Convert Video Files
Theoretically speaking, this way doesn't increase video conversion speed but it does shorten the whole video conversion time. When you have a great number of videos, you can apply Batch Conversion Mode of Pavtube Video Converter. You can choose multiple video files to start the video conversion process. And you can check "Shut Down Computer After Conversion" so that you don't need to wait the ending before the computer. The flaw is that you only can batch convert multiple videos to one format when you using Batch Conversion feature.
When you have a computer geared with CUDA-enabled graphic cards and you can accept H.264 or H.265 codec, encoding video with NVIDIA CUDA is the best way to increase video conversion speed. If your computer is low-end, you can try other 3 methods to shorten video conversion time.
