Partially transcode big file

Hi!
I'm doing some test rendering, is it possible to partially transcode input file with FFAStrans?
With ffmpeg I use -t ans -ss options for this.

Hi @molavex

welcome to the forum and thank you for using ffastrans!

You can try the Api_Set_In_outpoint.xml example workflow, just ignore what the thread is about, you don't need to use any api stuff for it.

The first processor lets you safely set in and outpoint.

The middle processor is a custom avisynth which takes the variables that you set inn the first processor and instructs avisynth to cut the file as you wish.

Hello Movalex,

You can also use a custom ffmpeg node and just type :

Code: Select all

-ss 5 -to 10 -vcodec copy -acodec copy 
Replace "5" and "10" by what you want.
Add %s_original_ext% in extension box to keep your original extension.

To resume :

Monitor folder>custom ffmpeg>delivery node.

Hope this helps.

;)
