I occasionally use open shot video, I don’t really do much video editing really- but sometimes I need to chop stuff up and lately I’ve been getting interested in doing concept films and collages of weird visuals and images to stick up on you tube. The odd thing is that the last few times I’ve fired it up the finished video has no sound.
I have recently upgraded from one version of Ubuntu to a newer one, so that might be the root cause.
First off- YOU GOOGLE THE BOOGLE. This usually provides me with-
- Virtually nothing of use
- Heaps of brain fucking options
Lets see how that pish works out…..
Found this hint in Handbrake documentation. Openshot defaulted to AC3 surround sound. Changing to AAC made the audio compatible with more programs.
” In an MP4, you can store MPEG-4 video created by ffmpeg or x264.
It stores audio in the AAC format. It is also possible to pass through Dolby Digital 5.1 Surround Sound (AC3) audio from a DVD in an MP4 file, although it is a new standard and not widely supported. Perian and VLC can decode it, and the AppleTV can pass it through to a surround sound receiver.
MP4 also supports chapters, for which HandBrake uses Apple’s chapter format.
MP4 also is capable of storing Variable Frame Rate video.
Be aware that chapters and AC3 audio can only be seen by QuickTime if you change the file extension from .mp4 to .m4v. HandBrake will do this for you automatically when you enable those features, although this can be disabled in the preferences if you really want .mp4 at the end of the name.
The MP4 format can also be optimized for “fast start” progressive downloads over the Web.
It can also include “soft” text subtitles that can be turned on or off, instead of always being hard burned into the video frames. ”
