Touching off easily
For this website, I have been converting media files a lot. You know, the photos I shoot are really big which leads to long page load times and screen-filling images. While it is quite easy to reduce their size, and increase JPEG compression, it is a lot harder to do so with videos.
WTF, VLC?!
I’m using the popular vlc player and somehow I didn’t seem to get it right. Either my video doesn’t turn out in greyscale as I planned, the output file is empty (Use
H.264
, instead of H.265
to fix), the aspect ratio seems distorted, or the video suddenly has rotated which I neither wanted nor expected to happen.
This series of steps help me (and maybe you, too) how to make simple video conversions like
VLC has a quick-preview feature for the most common filters in the Tools -> Effects and filters
menu. This directly affects the video you’re viewing, but won’t affect your saved file. It’s just meant for you previewing and controlling the effect properties these filters will have on your video. View this VideoProc blog entry for in-depth guides - and - more importantly - many images stepping you through. For the impatient fraction: continue reading 😉
To save a filter that you selected for your preview, you must add them to the conversion profile. As long as they remain ticked, any save with this profile will modify your video, eventually even although you unticked all changes you made to the preview filters in the past!
