AVHD Compression conversion advice needed

[zack28]

Hi

I was wondering are the .MTS files from my Camcorder Legria M306 already compressed HD (not Raw) and can't be compressed any further without lost of quaility. I was under the impression that you use the same method as i did with Standard Def (720 x 576) conversion where you would transfer the RAW footage from a DVI tapecamcorder (GS200EB) via IEE1394 then re-encode to Mpeg2 or DiVx. or VOB for DVD video




My GOAL is that i have a transfered my files from my SD card to my PC hard-drive and i have to 2 folders Stream 1 and stream 2 both folders take up 43 GB of hard disk space

Is there a way so that i can fit the footage (all 43GB) onto one blu-ray disc (25GB) in MKV format without losing quality or is that not possiable.

Also the same question again

Is there a way so that i can fit the footage (all 43GB) onto one blu-ray disc (25GB) in Blu-Ray Video disc for home blu-ray players without losing quality or is that not possiable.




advice really appreaciated as i'm stuck on what to do

thanks

The format is AVCHD which is compressed h.264. AVCHD h.264 is about 3-8x more compressed vs. DV.

Ability to compress further without substantial quality loss depends on your shooting conditions (e.g. tripod, good lighting, low noise).

Your listed computer is too weak to edit or even play AVCHD. You can use MultiAVCHD to create an AVCHD disc that will play on most Blu-Ray players. Try to avoid recompression which will take ages using a 1.7 GHz Centrino.

Not possible 43 > 25

You would have to re-encode it to fit to 25GB

BD comes in 50GB as well, this way there is no quality loss. Or divide it up to span 2x 25 GB discs

Many thanks for the answers

my Notebook is

Dell XPS M1710
Intel Core 2 (T7600 @ 2.33GHz)
2GB Ram
Nvidia GeforceGo 7950 GTX (512mb)
160GB HD

Windows XP performance edition (sp2)

would this not be enough power to re-encode HD,

The other point was that i had a MKV file of Terminator Salvation,(1920 x 1080) the file size was 12GB in size and the quality was awesome , how was it possible to get 25GB down to 12GB without losing quality, thats what i want to do to my files how would i re-encode my .mts files to achieve this

thanks

Your profile shows a 1.7 GHz Centrino. Your newer laptop will be somewhat faster using 100% CPU. Watch the heat.

Because you were watching it on a small laptop?

Make quality comparisons off a large screen HDTV carefully watching action and dark scenes.

If you will only be watching on a tiny laptop screen, you could get a reasonable 1280x720 h.264 picture at ~8 Mb/s if you recode from the original disc. If you recode an mkv, expect generation loss.
