aspect ratio for all media

Recommended Posts

Hello I know this is more of a question appropriate for a video encoding forum but thought I'd as anyway. All media like audio bumpers, video bumpers, etc are 1:85 .,.. I have a cinescope 139" 2:35 screen. Anyone know an easy way to recode (crop) these videos to 2:35 without losing the audio format? I tried with VLC but audio comes out 2.0.  Adobe premiere doesn't support MKV so that's out. Any help or tips would be great..

Thing first thing that you need to make sure about is that the file's audio is actually in 5.1 or whatever it says it is.  I just downloaded a few clip to test my suggestion below and noticed that the audio was only in stereo for a few files, despite being listed as 5.1.

The easiest way that I know to do this is with handbrake, https://handbrake.fr/

You can go to/from mkv without converting it to something else.  In the Picture tab just change the size to 1920x818, with keep aspect ratio unselected.  In the video tab, move the quality slider all the way to the right at placebo quality.  In the audio tab make sure that the mixdown is set to 5.1.

You can also batch all the videos in a folder.

Let me know if this works for you, or if you have any questions.

Thanks for the reply, so I did try the THX eclipse short trailer, success in cropping to 2:35 but my receiverc is reading audio as multi-channel in. Also my rear back surrounds and front and rear height speakers are not outputting as they would with original trailer. I'm assuming that has to do with handbrake limiting audio to 5.1, will play with it a little more see if I can just retain the exact same source audio..

Ok I figured it out... in the audio section you select the codec and match it with source.. in the case its DTS-HD Passthru, They do have TrueHD as well so atmos should work. There is also an 'Auto Selection' which probably detects source. Anyhow I have some video bumpers and audio trailers to crop. Thanks again for the tip!
