Hello, this might seem an obvious one for very experienced users, I hope you reply only if you know what you re talking about.
I'm not really a very advanced editor, I use premiere, and you know when you export with media encoder and you get an mp4, h264 1080p of 4 minutes (youtube preset) that is sized 400 mb (alot of transitions/some grading and mixing) ! and that lags on media players, and then you convert that very same video by a simple converter and you get it to 140 mb...
why? because I don't see much difference in quality really between the first exported 400 mb and the 140 mb converted by freemake video converter! I thought the youtube preset already gives you a compressed product.
I know you can do the same conversion too with encoder but it just seems easier to to not play with all the settings there and keep trying for small size..
I hope someone could explain the matter.
the free converter could be using more delta frame and thus smaller file size. the smaller file size may also be improving disk read speed in playback. also, there's a good balance between resolution and bitrate. low res and high bitrate can sometimes look better than high res with low bitrate. this is called the bits/pixel ratio. handbrake makes good mpeg4 files and has presets too.
