![]() Dolby Digital (AC-3) and DTS are already compressed audio formats and there's little need to transcode them. Don't worry about converting the audio streams, unless any of then are LPCM. Not all deinterlace filters are created equal, but the default one included with Handbreak is pretty good. Also, if the DVD is a TV show in interlaced format, you'll want to deinterlace it at this step as well. There will always be some extra noise on DVDs that you can afford to get rid of. If you over-denoise a video, textures all turn into smooth plastic and people's faces look like wax figures, but it should be safe to apply NLmeans on at least the "Ultralight" level to every video you rip. You can also apply a weak denoising filter during encoding such as NLMeans denoiser to reduce the video entropy and decrease size even further. CRF=24 will result in lower quality, and smaller file size. CRF=18 will use more data to encode a high quality stream, indistinguishable from the original DVD, but at half the size of the original MPEG2 video files. I recommend using the libx264 encoder with the slow or very slow preset and CRF value somewhere between 18 and 24, depending on how much noise is in the video. ![]() For most DVD, it's fine to use Handbrake and it works great on Mac. Start transcoding the MPEG2 video into MPEG4-H.264/AVC format.But wait on that for a second because the next step will take a while and you'll want to get that started first before you take on subtitles. The DVD (and therefor the MKV files) contain subtitles in VOBSUB format, which is a bitmap format (made out of pixels, not letters) that is supported on DVD players and BluRay players, but most smart TVs and streaming devices do not support it. sub files using ffmpeg or any other tool. Extract DVD VOBSUB subtitles from the.If you have a 24x-speed DVD drive in your PC, it will take about 2.5 minutes to copy the data. No video conversion is happening at this step, so the process should be about as fast as your DVD drive can read the disk. ![]() VOB files containing encrypted MPEG2 video data and VOBSUB bitmap subtitles and extracts it to unencrypted MPEG2 data and VOBSUB bitmap data contained in MKV format. ![]()
