No video frames found - VirtualDub 1.5.10 How is that?

[nightflight]

Hi,

Let me first thank each and every member here for a great video editing informational resource. I've used the guides section many times with successful and superb editing results.

The issue I'm addressing here has no prior reference in this forum, at least AFAIK, and as my searching here gave no results.

I have this nasty problem with 2 gigantic video files of a friend; it is his wedding party, and the capturing was made by the folks who did the shooting, and it seems they did not do a good job.

What I want to accomplish is to join the 2 files, unifying the resolution at 384x288 in the process, and producing a single output file that would fit on one (or perhaps 2) 700 MB CD using DivX codec format.

The capturing was done using, apparently, an ATI All-In-One-Wonder card, and I used AVICodec to identify the file formats. Results were:

Wedding1.mpg:
File: 1.30 GB (2.40 GB), duration: 1:21:21, type: MPG, 1 audio stream, quality: 70 %
Video : 2.27 GB, 4000 Kbps, 25.0 fps, 320*576 (16:9), MPG2 = MPEG 2 (SVCD/DVD), Supported
Audio : 130 MB, 224 Kbps, 44100 Hz, 2 channels, 0x51 = Mpeg-1 audio Layer 2 [0xc0], Supported

Evidently this file is compressed, as indicated by the 1.3 GB file size and the 2.4GB actual size. AVICodec identifies the Video codec as MPEG 2 and the audio codec as MPEG 1, and supported indicates that I can play it on my PC, which is correct. However, when I try to open this file in VirtualDub 1.5.10 it gives the error:

No video frames found in MPEG file

How is this? What is wrong here? And most importantly, how can I come over this error?

The second file Wedding2.mpg:
File: 297 MB (294 MB), duration: 0:29:56, type: MPG, 1 audio stream(s), quality: 55 %
Video: 246 MB, 1150 Kbps, 25.0 fps, 352*288 (4:3), MPG1 = MPEG 1 (VCD), Supported
Audio: 47 MB, 224 Kbps, 44100 Hz, 2 channels, 0x51 = Mpeg-1 audio Layer 2 [0xc0], Supported

This file opens in VirtualDub with the following warnings:
MPEG Anachronistic or discontinuous timestamp found in video stream 0 at byte position 4664, from 0 to 63280. This may indicate improper join.
MPEG Anachronistic or discontinuous timestamp found in audio stream 0 at byte position 6988, from 0 to 65631. This may indicate improper join.

Now given the above, what I want to do is:
Join the 2 files, unifying the resolution at 384x288 in the process, and producing a single output file that would fit on one (or perhaps 2) 700 MB CD using DivX codec format.

How can I go about doing this?

Thank you very much for your kind help.

I don't think Virtualdub handles mpeg2 streams. Try Virtualdubmod or Virtualdubmpeg instead.

Exactly. VirtualDubMod should do it.

Thanks a lot, VirtualDubMod did the trick and opened the wedding1.mpg file without errors.

I'd really be grateful for any hints or direction to a guide that will explain how to join these 2 files (wedding1.mpg and wedding2.mpg as described above), any pitfalls I should take care of, since as you can see the files are in different formats (MPEG2 and MPEG1) and different resoultions (320*576 (16:9), and 352*288 (4:3) respectively) as well.

Also, I'm concerned of the warnings given upon opening wedding2.mpg (the discontinuos timestamp warnings). Will they give me real headaches or what? Anything I should consider?

Thank you very much.

you cant join them in v-dubmod as meg files .. convert them first to divx and the join them ....

less chance of audio sync problems ...

btw -- mpeg2 is apx 25:1 compression (roughly) so a 1GB fie would be 25GB

you should see if you can get the origianl tapes - as the quality wil be quite poor to say the least ..
