Then, inside codec you must be sure to select appropriate color space handling, as well. Look at the button labelled Pixel Format next to the Configure button, where you can use internal conversion that will be supplied to the codec itself. VirtualDub2 > Video > Compression... > x265vfw For example: RGB24 -> RGB24, YUV 4:2:0 -> No Change or you can select options such as Convert To YUV 4:2:0 or Keep input colorspace, and so on.
When it comes to pixel formats (color space), it can be tricky, because what you feed into codec must be something that codec will understand and process properly. It was frustrating, because tweaking and testing every option available in the codec’s setting panel (including various color space conversions and mix-and-matching) didn’t seem to work and make it go away! No matter what we tried, it just couldn’t start video compression process. Of course, it is more CPU intensive codec and file playback will not run smoothly on older computers and devices!Īnyway, back to our problem. Another reason is that even in lossless compression mode it achieves considerably smaller file size at the output, depending on the source material (it’s not always the case, though, according to our experience, sometimes x264 achieves slightly smaller file size output with lossless single-pass mode). Audio compression and interleaving In AVI files, the audio track is usually handled by an mp3 codec but you can choose another codec in the Audio menu if you wish. Click on configure and select single pass as this is the easiest way to compress. The reason why we should use x265 VFW HEVC instead of a good old and proven x264 VFW AVC solution is that it can achieve smaller file size with equal visual perception of compressed material quality. Open VirtualDub, click compression from the video menu.
