Adding a black frame without re-encoding?

[Disco Makberto]

Greetings, fellow readers!

I am looking for a sotware that can add natively (wihout importing) a black frame to the end of an MPEG video clip and that does not re-encode the whole video clip. I recall that TMPEGenc DVD author can do this, but the file needs to be imported. Others do what I am looking for, but they re-encode the video. Do you have any advice, please?

What is the problem with importing a black image or short mpg clip ? So long as it can be added without re-encoding, what is the problem ?

Hello, Gus1inger!

Technically speaking, no, there is no problem taking your approach. It is just that it's easier and faster by doing it within the same software. Incidentally, it appears that Premier 6.5 (and I guess newer versions) allows for this, but as you know, this software is more on the expensive side. I am sure there are other options, though.

Does any of our readers know? Please post to the group.

Thanks again,

I believe that Premiere will re-encode unless you also have the MainConcept Mpeg editing plugin. Unless one of the smart mpeg editors, such as womble vcr, can do it, joining two clips might be the quickest way.

Hey, Gus1Linger!

Yeah, Premier Pro with the plug-in is a solution (EdDV informed me about), but it is rather an expensive solution.

Next to that, as you are kindly pointing out, is an MPEG joiner. After trying and trying and getting frustrated with about 6 or 7 or more MPEG joiners/Video joiners/Movie joiners, I found one that is stable and doesn't take too long to accomplish tasks: DigitByte MPEG Joiner 2.0. Thus, please let me ask you some questions about "adding a black frame to the end of a video":

1) Where can I find a 2 or 3 seconds MPEG video with black screen? After joing such to a video clip, I can re-edit the new file and choose how many actual black frames I want after the ending of the original video.

2) As you might know, this joiner needs that both original and black screen file have the same specifications. However, my black screen file will obvioulsy be without any sound. So, let's say, if my original video has AC3 audio, do I have to re-encode the black screen file with a "silent AC3 sound" so that both files can be joined? How do I go about this?

If any of our readers can also help, please advice.

Hi-

1) Where can I find a 2 or 3 seconds MPEG video with black screen?

Huh? Make your own:

BlankClip(Width=720,Height=480,Pixel_Type="YUY2",F PS=29.97,Length=90)

Install AviSynth and create an AviSynth script file, name it BlackVideo.avs or some such, stick that one line inside, and test it out by opening it in VDub(Mod) before sending it to your encoder.

That AviSynth script will make a black video 90 frames long (3 seconds at NTSC 29.97fps). That pixel type is for CCE. For TMPGEnc make it for RGB24. Adjust the Length, FPS, Width, and Height as needed. Run a 1-pass OPV or CBR encode. It'll take about 5 seconds to set up and 1 second to encode. Join at the authoring stage.

You won't need to create any silent audio for it, as long as it's at the end of the video.

Hello, Manono!

What a great advice! So thank you for sharing it with us.

I just would like to add the following:

For those of you who are using NotePad as the text editor, remember to save "BlackVideo.avs" within quotation marks ("" ""). This is to force NotePad to save the file as "avs". Otherwise, it would be saved as text.

Kindest regards,
