Reducing the size of MP4 files without degrading the quality too much..?

[Garrett]

Anyone know of a simple way of doing this (preferably free) ideally with the option of resizing & changing the aspect ratio.


I've been using TMPGEnc which is pretty good but often produces results with out of sync sound & HUGE file size.


Thanks.

Try handbrake: it can encode h264 with a simple slider for quality. You can also downmix to 64kbps mono aac for additional savings.


Handbrake has a simple list of presets (profiles) for different devices for you to try. For the Pandora,I chose Android high quality and tweaked settings til I was happy with the results.

Thanks I'll give it a try, it's actually for a Nexus 7 & the media importer app (streaming from usb storage)

you could just use ffmpeg and the terminal try something like this:

 ffmpeg -i <filename> -vcodec libx264 -vprofile high -vpre slow_firstpass -s 960x544 -b:v 4500k -maxrate 1000k -bufsize 1000k -r 23.976 -threads 0 -acodec libvo_aacenc -b:a 128k -vol 384 -ac 2 <filename>

works for me when converting vids for psvita of course you can change the resolution to whatever you need it to be,
