How do i merge 2 AVI files together before i convert them to 1 MPG?? Is it better to merge before conversion or after conversion? Is it possible to merge so perfectly that you wont have the slight pause at the point of merging?

Try VirtualDub. Open one file and then use "Append AVI Segment" to "tack" on the second file to the end of the first. I have done it many times and I can't see any "glitches" whatsoever, where I merged the two.

heres the proper guide for what you want -
The Vdub method works if the files are the same...codecs, resolution, frame rate etc. Otherwise, after encoding is the only way. If you're burning to (S)VCD then you don't need to merge the files. Load the mpegs into VCDeasy and burn as a batch, as long as they will fit in one disk of course.

When i open the files in Gspot they are the same,when i try and append in Vdub i get an "The audio streams have different sampling rates" if i wiev file info in vdub the files are also the same there..Why do i get this error??
Is ti possible to merge when converted without a glitch in the stream??If it aint broke, donīt fix it.

I've never joined mpegs but I have heard of "pops" created where the files join. I always join before converting b/c if I go 3 disks then the join is in the middle, and I like to stop the disk at a scene change.
It's a bit of a pain in the a$$ but here's what I do when I have your problem:
1. Strip the audio into a wav file for each part. Use Vdub if you can or Goldwave if it's AC3 or MP3-VBR.
2. Interleave the wav audio back into the avi. In Vdub open the first avi, select wav audio and open the first wav file, set both audio and video to direct stream copy, save avi. Repeat for part 2.
3. Join the 2 parts. In Vdub open part 1 (with the wav audio), select append segment and select part 2 (with the wav audio), save wav will save a complete wav file, set audio to no audio, save avi saves a complete video file w/o sound (it's much smaller).
Use the avi as your video source and the wav as your audio source.
Good luck!8)

I have tried using the AVI merge guide here on the site,but all i get is a file where one half is fine,the other way out of synch. This i get even if i use the mp3 freeze method.. I am now going for yuur guide Zippy,hopefully it will work
If it aint broke, donīt fix it.

OK, Zippy what i got now is an audio stream that is 1 second shorter duration than the merged AVI. Will this be a problem when converted to DVD compliant mpg?? Should i use vdub and merge the wav back into the avi,with the option "Change so video and audio durations match" ?? Or should i just try and see if it will work out (it takes forever to convert to dvd mpg)
If it aint broke, donīt fix it.

Don't do a full encode, you're probably going to get a gradual sync problem. Do a 2 min. test encode towards the end of the clip if you want to check.
You need to stretch your audio to match the video duration. Time Warp in Goldwave can do that, but you need to calculate your video duration first, and as accurate as possible. Here's how:
example 150,000 frames / 23.976 fps = 6256.2563 sec.
6256.2563 / 60 = 104.271 minutes
104 minutes = 1 hr 44 min
.271 minutes X 60 = 16.256 sec
Duration is 1:44:16.256
Use your total frames and fps then use your calculated duration in Goldwave. Good luck!"Art is making something out of nothing and selling it." - Frank Zappa -
OK,i did a full conversion during the night,just to see what would happen. What happened is not good,the video apparently got 27 minutes longer than the 2 parts are together in all,how the hell did this happen?? When using Gspot they are the same bitrate,codec and audio,could it be that this is not entirely acurate?
Isnīt it enough if i use the option "Change so video and audio durations match" ??If it aint broke, donīt fix it.

Before you stripped your wav files and before merging, did you scan the two avi's for bad frames? They can cause all kinds of problems. I don't know how the video gets longer!?
If you change so the a/v durations match, then vdub alters the framerate of the video. I think you then have to select "do not frame rate convert" in TMPGEnc, otherwise it gets changed back. You can try that, I've seen a guide that used that method before."Art is making something out of nothing and selling it." - Frank Zappa
