TMPGEnc: Cutting a Few Keyframes Out of an MPG?

reman · #1 10-23-2002, 04:21 PM

After getting the following error message from VCDEasy:

Quote:

invalid mpeg packet found at packet# 113845 -- please fix this mpeg file!

I found a bad couple of frames in the middle of a movie.

How do I cut those out without re-encoding the movie? I do not have the original file or an AVI/DivX to work on.

Hi reman,

Try de-muxing with TMPEG, and then remuxing again with BBMpeg.

So I would not cut the area out but by demux & remux it might "fix" the bad area.

In VDub I did goto the area and found that there are some messed up frames that appear to not bother WMP. BTW, found the "area" when I noticed VCDEasy only loaded X seconds...

I have never used BBMpeg so I will give it a shot! As always, Thanks!

Well...I tried to do that but the de-mux stops at the problem part. I even tried using TMPGEnc Tools to cut file around the problem but the 2nd half errored.

I have attempted to fix the problem in vcdgear and it produced a new file that was slightly smaller but still would not burn or de-mux. In VDub I see the few frames that are "bad" but it does play. Now what?

if you have enough hd space you can convert the mpeg back to AVI (compress with huffy to save some space) with VDub and you can manually remove the bad frame(s) and reencode it. This is the long way around the problem

Save space with Huffy? I do have space but I would think 85 min would make 1 BIG file.

I actually thought of this but wanted to avoid re-encoding and losing quality...oh well! Maybe I should use DivX 5.02 to save space

Huffy would make ~20 gb file whereas uncompressed avi would make over twice as much. I haven't found a good mpeg corrector yet- vcdgear seems to make everything worse everytime I've tried it

If it's an mpeg1 you could try open it in V-Dub. And run scan video stream for errors. I Think it add a mask into corrupted frames. And then frameserve to Tempgenc as a new file.
Or open mpeg cutter in Tempgenc. Cut the movie into 2, exclude the bad frame. And join the 2 parts again.
