hay guys..
An Mini Guide to adding "Filtering" to an already made MPEG-1 clip
------------------------------------------------------------------------------------------
you don't have to re-encode your MPEG-1 clip, and end up making it
even worse (than it already might be anyways) ..
Apps you'll need are:
1, Virtualdub
2, any MPEG-1 editor ie, M1, TMPG etc.
instead.. try this:
* first, load your MPEG-1 clip into vdub
* next, make sure you do NOT have "Video/Direct Stream Copy" enabled.
..rather, keep it on "Video/Full Processing mode"
* next, since you want to make a FadeOut at the END of your clip,
..select (highlight) the video via the time-line using the begin/end
..markers, ie, press Ctrl_Lt, and then select the
/__ and then
..press Ctrl_Lt, and then back video like 2 seconds to your left with
..the Crsr_Lt and note the seconds readout on bottom of time-line.
..and then finally press the
__\ button (this is your markout)
..NOTE.. remember to jot down the time-line's number readout, for
..later joining (hopefully, accurate)
* next, press delete..
* NOW, you have the last 2 seconds (or whatever time length you chose)
..in your video window. It's now time to SAVE this small video clip..
..so proceed to save segment - - could cost you anywheres from 25MB
..to 50MB (or more) depending on your captures' resolution size ie, 352x480
..or 720x480 etc. because it's saving it as an RGB format, NOT as an its
..original MPEG-1. vdub won't save back to MPEG-1. So do bare this in
..mind when working this way w/ MPEG-1 clips under vdub.
.
Ok, so now that we've finally saved our last 2 seconds clip, it's now
time to proceed to the next step..
.
* open an AVIsynth (*.AVS) script file or start a NEW one for just this
..project, and maybe call this script, FadeOut.avs and bring in this new
..fade.avi clip into the script
* now include in your AVS script, this line:
..making any adjustments to number bewtween () per your cut length
* SAVE this script ie, fade.avs
.
ok, NOW we JOIN our original MPEG-1 clip plus our new fade.avs but..
here's the trick he he.. don't loose me here..
.
* open your MPEG-1 editor (whatever you use for MPEG-1 edits/cuts/joins)
* first, bring in the original MPEG-1 clip
* then, remembering those numbers in the time-line (above) proceed to CUT
..the last 2 seconds out (or whatever seconds you used in YOURS)
..this is where you'll replace the last 2 seconds w/ your fade.avi clip.
* so, using your MPEG-1 editor, highlight the last 2 seconds and CUT that
..out -- ( i ment the video clip he he.. )
* next, insert or import your fade.AVS script (note, or if encoded to an
..MPEG-1 clip, should work then)
* now, proceed to re-SAVE..
* Vualla.. you're done. well, almost..
I don't know for sure (untested) if your MPEG-1 editor will JOIN that
last 2 second *.AVS script. It may have to be encoded to MPEG-1 first,
THEN for SURE, you'll be able to JOIN the two together. and again, Vualla..
a nice fade out at the end of your MPEG-1 clip.
Note 1, of course, this could be adapted to MPEG-2 clips as well. Just
do a little experimenting on a few first. I can't speak for every MPEG-1
editor and their features out their. Only you know what works or not.
But this is the easyiest, quickest way (w/out re-encoding the whole clip)
Note 2, you could ALSO apply other filtering ideas to this process.
Note 3, who cares about "quality" for the last 2 seconds!! At least your
99.99 % MPEG-1 clip will be whole.
Let me know if this works (for anyone)
Good luck to you guys.
