Just got a ps3 to stream my mp4's across from wmp so have spent loads of time converting them or at least trying to find compatible settings which I eventually did.

Then I thought why not just extract the m2ts file stick it in my video folder and see if that works; lo and behold it streams flawlessly from wmp and I don't have to bother with encoding/compressing and the quality is superior.

If I only new this before I spent days encoding and compressing my files to less than 4gb:)

Why is it that people encode when they can just extract the m2ts? Especially when hd space is so cheap.

I like encoding to 4GB purely to have them locally connected on an external HD. Fine, you dont get bluray quality but theyre still nice on a 50". Having an entire movie library on the end of your remote...priceless.

Unbelievably in this day and age the PS3 still can't read NTFS formatted drives so streaming is the only way to do >4GB files anyway.
 
why not just use something like PS3MS to stream, which transcodes on the fly if required?

Not entirely true, the internal HDD in the PS3 can read files larger than 4gb, I currently have a 8gb movie file on my PS3. But you are right about the PS3 not being able to read external drives in NTFS, so I had to copy the file over my network. ;)

A little note to the OP though,

A standard DVD will have an mpeg video encoded at 8mb max bitrate.
Now if you was to encode that video with the h264 codec at the exact same 8mb bitrate, you will wield a much smaller file, and you would have exactly the same quality as a simple m2ts extraction.
So it was actualy more beneficial to encode them in the long run :cool:

This is just for blurays not dvd's which I do differently. Extracting a certain movie in m2ts for example yields a file at 30gb with a bitrate of 35mb/s. I wouldn't even hazard a guess at how big that would be as a h264 mp4. I'm not even sure if you can stream an mp4 over 4gb through wmp to the ps3.

I;m no expert though but it is also quicker to just use m2ts as my endcoding software has an issue with converting directly to a compatable mp4 file on my ps3. So I would have to got m2ts from the disc and then use handbrake to convert to h264.
 
Yeah, handbrake is ok to convert the videos, but I think if you still got problem, maybe you also can try the profeesional M2TS converter like iFunia AVCHD converter to do the converting.

Have you tried MeGui yet? it is by far the best encoder for mp4 and mkv formats there is.
It has the best PS3 and PSP profiles for flawless mp4 playback, the end result of quality is much higher than handbrakes also, problem is though it's twice as hard to learn without a good step by step guide to follow.
 
No Haven't tried it but I;m naturally lazy. I found ripbot too complicated too but may have a look at megui.

Thanks for the tip:)

I use Ripbot for my rips, certainly not complicated, but damn s..l...o...w, average encode of a Bluray to 4GB m2ts is 8 hours!!

My PC is on 24/7 (Im backing up my original blurays to 4Gb rips for quick access via 2x 1TB externals)
 
Discovered a problem with just extracting to the m2ts file; namely on some movies I cannot seem to find a way to remove the damn commentary from the audio.

For instance on one movie I have the following streams (excluding foreign)

DTS HD
AC3 5.1
AC3 2.1
AC3 2.1

No matter what combination of the above I select or remove I either get no sound at all or sound with commentary; so damn annoying listening to some ass tell me " about the light shinging behind the fox logo....."

However if I extract to mp4 or mkv and just select DTS HD I get the sound with no commentary; really strange.

From reading about it seems m2ts will only play the first audio track no matter what it is, obviously the first audio track on this is commentary and when I remove it it still sees the audio track but I guess sees it as blank. I guess I need someway to actually remove the flag that it is the first audio track in the file?


I'm so confused :(

Get a program called TSmuxer

You can take out the audio streams you don't want and then remux.

Figured it out now. The DTS HD stream works fine in vlc, my main issue was that my audio setting in my ps3 were on linear pcm 2.1 as I only output to my TV. The PS3 can decode DTS HD just fine but it outputs on channels which my tv doesnt have, i.e. I could stream it in DTS without commentary and could hear music, background noice etc but no speech. I presume you need a proper amp to be able to hear the lot.

Anyway I decided to use eac3to to convert the dts stream to ac3 and then remux with tsmuxer. The difficuly is in syncing the damn video and audio streams. Maybe it is just easier to buy an amp:)
