Audio Conversion for an existing video file

[Terfyn]

Recently I bought a LED based video projector. I downloaded an existing video rendered to AVC/H.264 format to play back on my Blu-Ray player. When I tried playing on the projector, there was no sound. Now I am told, this model will not play Dolby based audio.

The AVC/H.264 option defaults to Dolby so would not play on the projector. There is an option to customise this render format to convert the audio to LPCM sound so I re-rendered the video, downloaded it to my USB stick and now it plays the audio perfectly on the projector.

This seemed a major exercise to re-render all my existing videos from scratch so I tried downloading another video directly from its rendered file. I re-rendered it using the LPCM format and this also played back in the projector I found that the advantage of re-rendering an already rendered video was that the new render only took seconds compared to the original. I can go ahead and convert my other videos to the changed audio format.

I thought the process of directly re-rendering from a completed video may be of interest to anyone needing to do format changes within VS. It also shows the benefit of rendering directly to a file, in VS, rather than a DVD although I suspect that the same download process could be used for a video recorded directly to a DVD.
