See the Aegisub page on the topic for a discussion of advantages and disadvantages. Softsubbing means instead just adding some text and instructions on how to draw it to the video file, and then relying on users’ machines to draw the subtitles. Hardsubbing means burning the text of subtitles into a video as an image. In this post, we’ll quickly look over how to transform some input video file in any reasonable format into another video in a reasonable format with subtitles attached.įirst things first: some terminology. VS2012 project files.So this evening I had a bit of a battle with the learning curve of subtitling a video for a friend, and I thought I’d try and save someone else having quite the same struggle! Split the sources to make them more manageable. Fixed a bug that caused garbled audio and occasional crashes near the end of playback. So for now, multichannel is down-mixed to stereo as before. There's tentative support for multichannel, but Virtualdub hangs when fed multichannel audio by an input plugin. Added support for 32-bit audio samples. Added support for planar audio formats. Minimized usage of deprecated features in ffmpeg. Upgraded to current versions of ffmpeg - avcodec-55, avformat-55, avutils-52, swscale-2. Therefore, above options in "Open video file" were implemented to convert to stereo or 16-bit if necessary. Virtualdub menu Audio->Conversion does not know how to mix multichannel down to stereo, or convert 32-bit audio to 16-bit. Some audio compression codecs do not accept multichannel or 32-bit samples as input. Note that virtualdub has some limitations when dealing with multichannel or 32-bit source audio: Limit Audio To 16-bit - converts 32-bit audio source to 16-bit samples (off by default). Downmix Audio - if selected, downmixes multichannel to stereo (off by default). When opening a file with the plugin, if you select "Ask for extened options after this dialog", you get the following options for audio Implemented full support for multichannel. The "Adjust Pixel Aspect Ratio" option is disabled by default Use the ask for extended options checkbox on opening a video to set them (There are many formats that virtualdub doesn't handle, now you can choose how they are decoded)Īdded more native virtualdub video formats, so less are converted to rgbĬhanged default format to rgb32 from rgb24Īdded option for FFMPeg autodetecting 709 colorspace - if that info is in the source fileĪdded option for setting 709 colorspace for source file height>=720 Opening file formats: anm asf avi bik dts dxa flv fli flc flx h261 h263 h264 m4v mkv mjp mlp mov mp4 3gp 3g2 mj2 mvi pmp rm rmvb rpl smk swf vc1 wmv ts vob mts m2ts m2t *.mxf *.ogm *.qt *.tp *.dvr-ms *.amvĬode: From raythe0n's origional plugin, modified by tateu, later modified by dlonerangerĪdded option, default video decoding format for unusual formats Source solution for vs2010 included (but earlier versions of the VS can be used) Implemented Media File Information dialog (File->File Information) for the first video / audio stream in the container file Both video and audio are always decompressed Simple downmix of multichannel audio stream alg implemented Supported YUV420P, Y8, UYVY, YUYV, RGB555, RGB565, RGB888 color spaces To install FFInputDriver just place the unarchived package under VirtualDub program directory. The plugin is based, as the name may suggest, of the FFmpeg libraries. FFmpeg Input Driver can handle 31 different file formats. FFmpeg Input Driver will open and edit Matroska Container (MKV), MP4, FLV and other video files in VirtualDub. You need a plugin or plugins to load anything else besides. VirtualDub, as stand-alone, cannot handle.
