For "Rate control" select "Single pass - lossless" unless you really need a smaller file and are willing to sacrifice quality.Also in the Output section / VFW FourCC, select x264.In the Output section, check the "VirtualDub Hack" checkbox.
VIRTUALDUBMOD MP4 CODEC INSTALL
If this is not in the list, use this link to download and install x264vfw. Select "x264vfw - H.264/MPEG-4 AVC codec" in the list of codecs.When using the x264vfw codec (linked above) with VirtualDub to encode video as x264, follow these steps. Choose a location and filename for the output video.Click the "File" menu item, then "Save as AVI.".Click the "OK" button in the "Select video compression" dialog box.Click the "OK" button in the "Xvid Configuration" dialog box.In that case, we recommend using a higher quantizer value. But for longer videos (e.g., longer than a minute or two), may produce excessively large file sizes. Note that a quantizer of 1.00 is essentially equivalent to zero compression. Choose "1.00" for "Target quantizer:" (If the button says "Target bitrate (kbps):" click it to change it to "Target quantizer:").If this is not in the list, use this link to download and install Xvid. Select "Xvid MPEG-4 Codec" in the list of codecs.Click "Video" then "Compression" in the menu.If it is not an avi file, use MP4Cam2AVI Easy Converter (mentioned above) to convert to AVI. When using the Xvid codec (linked above) with VirtualDub to encode video as Xvid, follow these steps. You should probably also set "audio format:" to "Source audio (no recompression)".

If MP4Cam2AVI hangs when you select the mp4 file, turn off Preview before selecting the input file. If you have video encoded as H.264 and in mp4 file format, you can use MP4Cam2AVI Easy Converter to convert it to avi format, then use VirtualDub to encode. If you don't already have a video encoder which works with the XviD codec, VirtualDub seems to work well.
VIRTUALDUBMOD MP4 CODEC FREE
Xvid and x264 alongside ffdshow-tryouts appeared to offer the best free solution for quality and performance. We at NBS have tried a few different codecs.
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). 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.
