H.264 AviSynth Help!

[Babalou]

Hi,

I have a couple of H.264 clips taken from my Mino HD that I want to add text and stack vertically as simply as possible. I have the AviSynth scripts written, but I do not know how to process them.

Super always tries to re-encode with the selected parameters and VirtualDub wants to convert to AVI...

Is there a way to apply these filters and save the output without re-encoding the videos? Kind of like when you do "play" and WMPlayer pops up, but save the output...

Thanks!

nope

when you use avisynth you have to re-encode , because it's frameserving uncompressed video

you could play that .avs in a media player as a "proxy" (i.e. use that .avs as if it was your video)

Is there a simple way to add static text over video (like subtitles) and stack video vertically/horizontally?
If AviSynth is the easiest, then how can I re-encode without losing too much quality?

[poisondeathray]

you can feed that .avs as input into an encoder that accepts avs scripts

e.g. staxrip or ripbot264 would be very easy to use. If you want more control, something like megui

Your avisynth file could be something as simple as this:

a=ffmpegsource2("video1.mp4").subtitle("Whatever text you want here", align=8) # don't know what container the Mino uses for H.264 video
b=ffmpegsource2("video2.mp4").subtitle("Whatever text you want here", align=8)
StackHorizontal(a, b)
#StackVertical(a, b) # uncomment if you want to stack vertically and comment out the StackHorizontal

Find the instructions for subtitle here. You will probably just want to play around with the align setting.

You can then pass that through the command line version of x264 if you want. Something like this:

x264 --crf 18 -o newvideo.mp4 video.avs
