One just needs to make a few clicks in order to enjoy watching of DVD movie on its MP4 player. Splitting of files, DVD ripping, selection of subtitle, angle, and audio can also be made with this kind of device. Various files of output can easily be played on iPhone, iPod, Archos, Apple TV, PSP, iRiver, PS3, Creative Zen Vision, and many other players of multimedia.Ī good MP4 converter also provides support for the technology of AMD APP and NVIDIA CUDA to the range of 5X rapid processing act can be delivered. The ripping of DVD to audio files can be done easily like conversion of DVD to M4A, MP3, and AAC.

It also assists in H.264/PSP AVC HD and H.264/4AVC/MPEG video formats. The great MP4 converter assists in the conversion of DVD to MPEG4, MP4, AVI, DivX, FLV, and video formats of XviD. In order to watch various DVD movies on the MP4 player at any convenient time, you need to get the DVD to an MP4 converter. Using a complex filtergraph, you can speed up video and audio at the same time: ffmpeg -i input.mkv -filter_complex 'setpts=0.5*PTS atempo=2.0' -map '' -map '' output.The DVD to MP4 converter allows you to digitize the standard form of DVD to various multimedia file formats which also can be accessed through mobile devices. The following with quadruple the audio speed: ffmpeg -i input.mkv -filter:a 'atempo=2.0,atempo=2.0' -vn output.mkv If you need to, you can get around this limitation by stringing multiple atempo filters together. The atempo filter is limited to using values between 0.5 and 2.0 (so it can slow it down to no less than half the original speed, and speed up to no more than double the input). To double the speed of audio: ffmpeg -i input.mkv -filter:a 'atempo=2.0' -vn output.mkv You can speed up or slow down audio with the atempo audio filter. Other options include slowmoVideo and Butterflow. ffmpeg -i input.mkv -filter 'minterpolate='mi_mode=mci:mc_mode=aobmc:vsbmc=1:fps=120'' output.mkv This is also known as 'motion interpolation' or 'optical flow'. You can smooth out slow/fast video with the minterpolate video filter. To slow down your video, you have to use a multiplier greater than 1: ffmpeg -i input.mkv -filter:v 'setpts=2.0*PTS' output.mkv

For example, to go from an input of 4 FPS to one that is sped up to 4x that (16 FPS): ffmpeg -i input.mkv -r 16 -filter:v 'setpts=0.25*PTS' output.mkv You can avoid dropped frames by specifying a higher output frame rate than the input. Note that this method will drop frames to achieve the desired speed. For example, if there are two succesive frames shown at timestamps 1 and 2, and you want to speed up the video, those timestamps need to become 0.5 and 1, respectively. The filter works by changing the presentation timestamp (PTS) of each video frame. To double the speed of the video, you can use: ffmpeg -i input.mkv -filter:v 'setpts=0.5*PTS' output.mkv

Note that in the following examples, the audio stream is not changed, so it should ideally be disabled with -an. You can change the speed of a video stream using the setpts video filter. Note that all of these options do require re-encoding the video. This is the guidance from the ffmpeg wiki. mkvmerge -default-duration 0:12fps -fix-bitstream-timing-information 0 original-video.mp4 -o temp-video.mkvįfmpeg -i temp-video.mkv -c:v copy -c:a aac -filter:a 'atempo=0.5' slow-video-with-audio.mp4 The example below assumes the source video was 24 frames/second so that audio needed to be slowed to half (0.5) speed using ffmpeg's atempo filter. If the video contains audio you can also slow that down without changing the pitch, but it is not a lossless conversion. Here is an example that changes a video to 12 frames/second: mkvmerge -default-duration 0:12fps -fix-bitstream-timing-information 0 original-video.mp4 -o temp-video.mkvįfmpeg -i temp-video.mkv -c:v copy slow-video.mp4 It requires remuxing the file to a different containter format MKV and then remuxing it back into an MP4. Lossless (video) remuxingĪs noted in the comments there is a way to do this where the video does not I know this is an old question but none of the current answers are the recommended way anymore.
