edit m2v and wav - any software??? - really need help

[phatpg]

heh

i captured video for my cousin doing his bmx videos onto my hd and converted them to mpeg2 dvd format which resulted in a m2v and a wav file.

There are 21 full length videos - so i didn't have the space on my hd to keep them on the original avi and thus am now having problems editing it - used premiere to capture and convert - but that has problems editing mpeg

I am in need of a suitable software that will edit the m2v file - i have been trying to do this for a week now.

have I made a fatal mistake by converting?? - hope not - thought all that would have been the hardest part - was definately time consuming enough

anyway - any help and suggestions appreciated


Thanks

Conversion to mpeg-2 should be the last stage before authoring, both to preserve quality, and because mpeg-2 is not designed to be edited. Having said that, it is obviously too late to go back.

There are a couple of things you could look at, including Mainconcept's mpeg editing plugin for Premiere, and WombleVCR. Both are designed to make editing mpeg-2 easier.

If you want to preserve quality, I suggest you restrict your edits to simple cuts, and avoid cross fades, fades in and out, and overlaying titles. All of these will require re-encoding of the video, and will cause some quality loss.

thanks - i feared as much - major blow - spent so much time recording and encoding - think i might kill someone!!!!!!!!

Hello,

because mpeg-2 is not designed to be edited

I don't know if that's entirely accurate (I edit my mpeg2 files from my hauppauge wintv pvr 250 just fine). Anyway, tmpgenc dvd author can take .m2v and wav files. Also, tmpgenc regualar can edit them together (free 30 day trial for dvd output - mpeg2 file).

so - you edit them with tmpgenc then?? - just the regualr version? - i'll give it a go and see what i can do - cheers

mpeg (1 and 2) are based around temporal compression, i.e. compression across frames in the timeline. Beginning with a full frame, the subsequent frames are stripped all data that is the same as in this keyframe. This occurs until the next keyframe. There is also compression within what is left of each frame. During playback, all this is reconstructed for your viewing pleasure. This makes it more difficult to get frame accurate edits. It is also a lossy compression algorythm (it throws away what it thinks you won't miss) and degrades very quickly if it is re-encoded.

This is not to say it can't be done, and cameras and cards that record directly to mpeg-2 are driving the need for programs that can overcome these issues, however this does not change the fact that mpeg (1 and 2)compression was not designed with editing in mind, and that it is a less than ideal compression to work in.

Ok I just wanted to say it's editable, even if its not ideal for it. It may not be perfect. But with mpeg2 cards that record in only mpeg1/2 it is all I have available. Thanks.

If you're using Premiere Pro, then give Mainconcept Mpeg Pro a try. There is a Trial version download available.

I don't normaly edit Mpegs, but I did try it out once to see if it worked. It actually worked quite well. I joined some clips, added some fades, tittles, even slowed down a section @ 20% speed. The results were pretty impressive, but I have no need to edit Mpegs, so I never did anything more with it.
