@shirtful - issues with your latest (Tia) vids

Being the kind soul that I am I thought I would try and help old sweatingbull out a bit and download one of your vids to see what problems he had.

Now I have all the codecs I need.

1. WMP11 - refused to play it
2. MediaPlayer Classic played it with visible distortion - pixel break-up at each edit
3. VLC player refused to play it beyond the first edit
4. VdubMod(the one that reads mpeg2) pleyed it with pixelation at the edit points
5. Cyberlink PowerDVD8(the latest?) played it with visible pixelation at the edit points.

My video editors which will usually accept mpeg2 (I do it all the time) did not recognise the clip as a valid file.

So frankly my friend I cannot see how your 'idea' of i-frame editing to retain as you put it the original quality (and I assume without any distortion) has actually worked.

There is a neat little prgram called VideoRedoPlus which edits out bits you do not need. Will not re-encode the bits that are left so it just does a direct stream copy.

And this is all a bit hard on guys downloading 900 meg of clips only to find that they may not work after all that.

for those who have no idea what is going down here.

An explanation.

in video compression the i frame = intra frame, also known as a key frame.
these are the complete frames where the complete image is stored.
In video compression to reduce the amount of data that must be stored, only the changes made from one image to the next are stored, this technique capitalizes on the fact that most video sources have only small changes from one image to the next. However when a drastic change to the image occurs, for example switching from one camera shot to the next a key frame must be created.

for example: The ETV Hotbird stream has a key frame somewhere between every 9 to 13 frames. My mp4 files have one every 24 frames or at a change.

In video editing, it is best to cut the scenes at a key frame, especially when no further encoding is to be made.

[hidden link - please register]no bugs, no Gia, no Brona, no pixel bursts. An mpeg direct stream copy that should play everywhere.

No laughter from here but agreement with DB's suggestions , also as regard VideoRedoplus.
I could suggest also BSplayer as player. You don't need the pro version, The freeware version is a good player and allowes to make caps.

You tried to remove all yours kodec and to establish them again
If is not present, necessarily remove all kodec from system and establish these

At you not a hardware problem

@relaxingbull

I am sorry (again) and I am sure I can hear the laughter about this engineering its way to deepest Italy.

But seriously, I can not recall any post by you where mentioned that you could not play my little filums. In fact it hurts me to realise that you may have been denied such an enjoyment.

The only thing I have changed in all that time was going from a dodgy DivX codec to a much better XviD one. Never liked Winamp so that may well be the culprit. The XviD codec is horrendouslyy expensive - it will cost you a massive 0 euros. That is right, it is FREE. There will be a link somewhere on this site how you can get it or just let Google be your friend. But the VLC player, which you say you have, is even more friendly and should play them even without the codec.

Ok guys, thx for all your efforts. My understanding of the whole thing is that the world was good to me in 2006 and 2007.

There were many hot shows and we all enjoyed many.avi files.Just one mouseclick and my winamp-player played them all. And my mp3 music.

But once upon a time a video artist kissed us to life by bringing the mp4-files into our little avi world. And DB decided to answer with a change in his avi files. Since then DB's avi files couldn't be played with my winamp software. Avi wasn't avi anymore for me.

But not enough, I needed VLC player for the mp4 files. Then I decided to make my own vids with my new Hauppauge tv-card. Since then I had my own mpg-files. :-(

But no prob, take the VirtualDub software and change it to avi files while cutting out the walrusses, the Gnubbels and butcher's daughters, it just takes some time. :-(

But that's history. I haven't changed anything. Etv has changed some parameters and every vid i made since then was a pixel-disaster. The reduced pixel rate of etv can't be handled by my tv card (100€).

Good vids are obviously a matter of price of the hardware and/or software.

And DB, you are right. I don't know what an i-frame is or remux/demux. I want only relax. :-D

I am sorry too.

I will take your word about the re-syncing issues for VideoRedoplus except to say that I use this a lot - all my TV6 clips were intially edited with this and as far as I can see there is no audio sync issue. But as your Tia clips are just using the original sound with no requirement for audio-sync I do not see the problem.

But if there is audio-synce issues with de-muxing/muxing (most members will not have a clue what this means) don't you just create these in the method you now suggest ?

But that is not the real issue. For most members, they download a vid and they expect it to work. They are not video experts and can not be expected to use additional software just to make a clip work. You might be concerned about 'original quality' most will not and their prioties in watching a vid are elsewhere. Surely it is better for all to offer a clip that is guaranteed to play in the majority of players without ferther hassle.

First of all.
I am sorry for anyone who has had problems play the Tia files.

Second
My method is very quick but rough. There is no Demux/Remuxing which can cause audio desync when joining mpegs, as is used in Videoredoplus, (it demuxes then remuxes and writes new timestamps and can cause audio desync which can increment with further joins).

I accept that there is pixelation at the end of the cut as the decoder is not expecting another I frame from the start of the next cut. Some decoders hang as the timestamps in the next cut are not in sequence.

For those who have downloaded my files, I'm sorry and the following procedure should allow the files to be played completely **but** with pixelation at each cut.

Using DGMPGDec 1.5.6 demux the vid, then run restream on the M2v and set timestamps to zero, then write a new M2v file, the new file will have the suffix (.0). Now remux using Avidemux taking note of the audio delay added to the audio mp2 file name by DGMPGDec 1.5.6
