Avidemux sound out of sync merge2/19/2024 It can also write out image sequences from video formats that are often easier to use in Blender than the original movie file. This works for me: avidemux3cli -load file1.mp4 -append file2.mp4 -append file3. VDub also has a number of tools for video processing and interleave adjustment. In VDub you can specify the WAV audio source and an audio codec (chosen from whatever you have on board your system), then write the multiplexed a/v to the. The Blender Sequencer (VSE) outputs its Mixdown audio as a WAV file. You can also click the Play button and click Stop when you reach the desired point. Use Drag the slider, click the seek buttons, or just plug an exact from or time in. You can use a number of audio sources for VDub but likely the most common for a Windoze machine is WAV. To move, copy, or delete a section of the video, you must first select it with the controls at the bottom of the video. VDub will read the entire sequence of frames (as long as they are properly numbered in sequence) if you just drag the first frame onto its icon or into its workspace. Probably the most common (and definitely the recommended) approach is to output a PNG image sequence from Blender. No scripts are needed to use it with Blender’s output. If you are mixing audio tracks in the VSE, you can do a Mixdown in the Scene>Audio tab to use with Virtual Dub.Ī workflow I use a lot is to make FFMPEG versions of short sequences as the work progresses, checking audio sync and animation quality, and when things are finalized, write a PNG image sequence out from the VSE, plus an Audio mixdown if there’s any mixing in the VSE, then do the final multiplexing in Virtual Dub to take advantage of VDub’s more complete configuration Richard Marklew – good catch, I wasn’t aware the 64-bit versions also exclude FFMPEG & other – Virtual Dub (VDub) is an Open Source video toolbox utility that is easy to obtain (just google for the download page) and integrates well into a Blender-centric workflow. Also, FFMPEG does not let you configure the Xvid codec – one clue that it isn’t really using Xvid. Make sure that in the FFMPEG Audio tab you enable “Multiplex Audio.”įFMPEG generally writes larger files than using Virtual Dub and the true Xvid codec, so if file size is a consideration, you should use the external app. avi file, making it unplayable in Virtual Dub unless you change the FourCC – the current Xvid installer includes a little utility to do that. Note that with 2.49b, if you choose the Xvid codec for video, it does not seem to actually use the Xvid codec – my tests indicate it uses another MPEG-4 encoding instead – and it writes the wrong FourCC code to the. You choose both video & audio codecs for use with FFMPEG. Use Altavista to translate it.FFMPEG is listed in the same drop-down as the AVI codec option. He is a very clever guy when it comes to these things.īefore I forget, if you’re good at Linux, theres a Mencoder tutorial on how to use Mencoder from the command line at see under tutorial> Dvix. If you have to edit or change the extension of sound file, use the program Audacity from, which is quite nice.īy the way, Malefico told me once that there is a way to set the wav sound files and and avi movie in Blender’s video editor, but I can’t remember at the moment, I will have to look through my notes. And 16 bit rate wouldn’t hurt either, but some people also use 32 float and it seemed to work. From memory, LiVES also works well with ogg files while Avidemux only likes wav files.Īlso be sure to use wav files that are 44100HZ for all these programs. The following command works (use -cat instead of -add for second file): 'MP4Box -add file1.mp4 -cat file2.mp4 output.mp4' In the end it made the audio out of sync though, so I still have no good solution. LiVES very easy to use, trims sound to video length, very forgiving program. 2) I ended up using MP4Box, but the example provided overlays the two video and audio streams. So if Malefico uses it, it must be good.Īlso another video editor which works just fine on Linux is LiVES from. Our suggestion: Use fast video cutters like VideoProc Converter AI instead of cutting videos. That may cause problems like video stuttering or full of glitches at the beginning, missing frames, video and audio out of sync, etc. Avidemux, is really nice and easy to use. A full set of video editing tools: crop, rotate, merge. Avidemux uses Mencoder, so thats why I said to download Mplayer first. configure -enable-gui, its much nicer, then the usual make, change to su, and make install.īut wait Tronovanm, theres more! Then install Avidemux video editor, from. If you want to glue your sound and film together, you first have to down load Mencoder which is part of Mplayer from. Yes Tronovan, there is a Linux Santa Claus! Ha,ha,ha.
