Unterschied M2T und MPEG

M2t difference and MPEG



Frage von darg:
August 2007

Hi folks,

I have a few weeks ago after many years with a D8 of Canon HDV Camera increased - HV10. The whole is a fairly big step forward, not only in terms of picture quality, but synonymous coding data.
The editing a supercomputer a la NASA requires MPEG2 is not a miracle but I bring the file extension to m2t hurl, I HDVSplit means of getting the camera. Is there a difference in the coding or is it simply a renamed MPEG2 File?
My main problem is that the editing of the videos with Vegas m2t is impossible without the support of NASA. Are the MPEGs encoded easier? I am unfortunately not as clear as with the D8 AVI was just huge, the editing of the video even smaller computers with absolutely no problem.
Now I have tried over the INet a few programs to get m2t with which I can convert to mpeg but they take every scrap show is not playable. I suspect it is the s.Widescreen HDV. The following programs I vesucht:

HDTVtoMPEG2, various versions, not all the videos ran.

MediaCoder, maybe I'm too Bloed the filter settings to understand

MPEGStreamClip have no MPEGCode for QuickTime - QT synonymous alternative is unacceptable, since the versions in the network no longer offer the MPEG extension

VirtualDub can not begin with the m2t.

Before I get at NASA with me around the corner in Mountain View computer rental time I wanted it here and try. A good forum with very good papers and good answers. Unfortunately, there was no to my questions. Maybe I can help a yes.

Gruss

M2t is Mpeg Mpeg video and audio to a stream verzwirbelt. For me (Mac) is sound (Mpeg1Layer2) of Quicktime is not supported, ie if I bellicose foreign material, do I have the file as a Quicktime HDV (. Mov) with Mpeg Streamclip to export. No big act, because only the audio file is repackaged.
But: When I capture, then in a QT compatible format. If your editing program itself does not capture HDV, it is very likely that you are not synonymous clever cut it.

For slower Calculator is the capture in a so-called Intermediate Codec advisable. No loss of quality compared to HDV, but is significantly (!) More disk space.



Antwort von darg:

So it is something different. I have several editing programs on my PC tries. Unfortunately, the calculator, which I have here is not the fastest. For SD it loose enough, even with Premiere Pro SD ran well but in the HD increases with the 3GHz for HD message out. Studio 10 would not really synonymous, Ulead10 synonymous not only Vegas 7.0 was able to load the m2t preview garnicht running when you cut Scenes Watch wants.
Is it what the Vegas m2t with the Scenes, which I took as MPEG wants to convert and if so, with what settings? The camera format is 1080 60i. The whole will be very slow but better than nothing.

Hi namesake,
Although I have no PC, but as I said is synonymous Mpeg m2t. If your calculator for HDV is too slow, you have to see whether there is a preset for capturing that are (so) Intermediate Codec is, then that is synonymous HD, but less compressed than HDV = requires less processing power.

Good for your calculator only for SD, you can still cut so HDV. You captures as DV and HDV cut "offline", ie, at lower resolution. Then you copy the entire off-Project in a Project and HDV captures again, this time as HDV. This process is called then "online". How exactly you instead, you have to be in the Manual of Vegas read.

Anything else: If you look at the VLC player with the m2t files that you recorded with HDV Split, you can not see, or if they get stuck or shakes, then it is really time for a new calculator. Because the only thing you have with the following two methods of ready-cut film could make would be to him as the SD DVD output. On the calculator itself, you can not see the HD, and back to the Cam is not synonymous, because off of the computer side from smooth play requires. That makes it no fun.

Hello Axel,

I have tried an original m2t of the camera to render as MPEG and then for processing use. It ran at least in Vegas as a preview, that is really what seems to be less encoded. My problem is that Vegas does not recognize the HV10 :-(
The calculator is not too bad, because with VLC I can view the m2t directly, only halt processing with m2t rafft him then. This was the thing synonymous never thought but I was hoping at least a little bit so you can make. The calculator that I get really wanted to use is in Germany, about 9000km away :-( Is only Athlon XP 2800 + with 2GB and I doubt whether it would create.
As with MPEG is better now, I search a batch level program, which converts the Scenes. This is what I mentioned above has settings that I have not really kappiere. Will play around a little bit since.

Thanks and greetings

Axel

Hello,

just wanted to briefly my solution to the problem computer kund do. Did my little HP Slimline Of Core Solo to Core Duo 2GHz with 2GB RAM and upgraded. Vegas is so appealing but it is slow. You could work with, if not only the calculator since the CPU would be constantly changing. Unfortunately, simple but I guess it is s.XP.
