Other MPEG-2 Editor

Is there a software application other than VRD and "W" that allows native editing of MPEG-2 files but with no recoding on save? I have an editing project that I need to complete completely in MPEG-2, and VRD is not the right solution. (It is excellent for its intended purpose.)

I've heard that Sony Vegas and Ulead will edit without recoding. but it is really hard to tell from the product descriptions.

No, Vegas will recode if the format is not DVD compliant. What is the source of your video and what resolution is it? Most NLE programs force DVD compliant resolutions. However, check THIS thread out. Supposedly there is a program, DVD Patcher, that allows you to edit the mpeg header allowing you to fake the program out. (Note to moderator, if I'm out of line posting the link or mention of the other program, please feel free to edit my post.)

Here's the whole story. My company produced a DVD that has MANY live action video shots. It was produced using Adobe After Effects. We need to make some changes to the content. Unfortunately, the guy who edited the video did a terrible job of organizing the files, so we are unable to recreate the scenes in After Effects.

As a stop gap measure, I would like to rip the DVDs, make the changes, and burn to disk. Since the files have already been rendered once from DVD, recoding the files would cause an unacceptable quality loss.

Since these files will be ripped from DVD, they are probably DVD-compliant. Since trying to use the VRD joiner for creating the scenes would be awkward, I don't think this request should upset the admins. The application is quite different from VRD's intended use.

Why are you expecting "an unacceptable quality loss" out of VRD? VRD sounds perfect to me for accomplishing what you want.

If you cut the scenes on I-frames, there will be no re-encoding. If you cut the scenes on anything other than I-frames, then there HAS TO be re-encoding regardless of what tool you use.

Although I try myself to cut on I-frames where possible, I have never seen a visual glitch when cutting on P or B frames either, using VRD+! :confused:

I wanted to post my question in the forum at your link, but you have to own Sony software to be able to post. (Haven't the heard of pre-sales questions?)

it's been a while since I registered, I didn't think you had to give a SN. I have Vegas (Movie Studio) and I'm sure others here do as well. What questions do you have. Hopefully I can help.

I just want to know that if I rip a DVD (using VRD's open from DVD), save the file as an MPEG file, and then edit it in Movie Studio, will the edited file be recoded by Movie Studio?

Saved a 2:45 min title I created on DVD and saved it as a mpeg. Made a few simple cuts in the video and added a couple slides. VMS took 15-minutes to render it to another mpeg file. I always use avi and render to avi in VMS so I don't know if 15 mins is normal or not or if it recoded or not. (probably did since cpu utilization was very high). This is from the help file:

Resample
(video only)
Select a radio button to determine how video frames will be resampled when the frame rate of a media file is lower than the project’s frame rate. This can occur either when the frame rate of the original media is different than the Frame rate setting on the Video tab of the Project Properties dialog.

With resampling, the intervening frames are interpolated from the source frames, much like a crossfade effect between the original frames. This may solve some interlacing problems and other jittery output problems.

Smart resample


Resampling occurs only when an event's calculated frame rate does not match the project frame rate and the project frame rate is 24 fps or greater.

The calculated frame rate takes into account any changes made to event speed with playback rate and undersample rate.

Force resample
The event is always resampled, regardless of its frame rate or the output frame rate.

Disable resample
No resampling will occur.
I found this thread in the Vegas forum:

Editing from DVDs and compression loss.

The answer is that Vegas Pro can be tricked into smart rendering, but it is not intuitively designed to do it. That's what I got from the link you posted. One of the posts says "All the medium and mid-range editing programs let you edit your DVDs without recompressing." However, the poster does not identify which ones "all" are. That is the purpose of my post.

Let me reiterate that if anyone knows a medium range editing program that will let me edit MPEG-2 files without recompressing, please let me know. VRD will be a part of the process, but the editing that I need to do is not the type that VRD was designed to do. For one example, I need transitions.

Okay, guys, thanks for all the input. We're probably approaching the danger zone here, so I started a new thread over at videohelp.com. My posts over there mentions how happy I am with VRD, to be fair and consistent!
