Title: Need some help on Video Encoding
Post by: Capcom on June 30, 2009, 12:23:23 AM
Are there any Video Encoding Gurus sa mga fellow menyeks ?

I need to downscale some movies encoded with 1080p to 720p (h.264) , problem is that re-encoding would result in loss in quality , tried using higher bit rates and other optimizations , pero result is malaki yung file size

Meron bang way to downscale it without losing quality ? as in maintain yung bitrate at etc

Wala na kasi yung source ng raw video sa akin...

Qualitywise, your goal should be the same as other 720p releases.  From 1080p to 720p - meron talaga loss.

er, why would you want to convert 1080p to 720p? to play on older machines perhaps?

anyway, i prefer xilisoft video converter for ease of use.. i can configure audio and video quality and auto-calculate corresponding video bit rate, and hence customize the output file size..

it would have been nice to use CUDA with badaboom, but my computer crashes after installation.. i wonder what's wrong..

resurrecting this thread:

i have a bunch of family videos taken using our P&S camera at home and it's eating up too much space...and i was thinking of encoding them to a different format so i can save up on space without compromising too much the quality.  any suggestions? thanks so much!

 HEVC/H.265 maybe?

What format are the videos stored as presently?

For me, just add storage, 2Tb drives are around ~3k

they're currently .mp4s in 720p since they're straight from the digicam.

any suggested/recommended program to convert them into something that saves more space? doesn't have to be the best in quality since they're just family videos.

Given that they're mp4 files they're most likely using h.264 compression already. If you want smaller file size you'll have to compress them using hevc/h.265, which is time consuming, has no guarantee of preserving the quality, and not as portable to play. Better to save for an external drive for backup/archival purposes.
