how to get avisynth to read sony xdavc-L file?

Hello, With a basic file using this profile in Vegas for rendering : Sony MXF HD EX 1280x720 60fps and avisynth+ x64 ( cannot guarantee for other versions ) FFVideoSource works for the video Code:

What version of ffms2 are you using ? vapoursynth has a timecube filter that can apply cube LUTS , but it hasn't been ported to avisynth. You can make a request

Hi, I use the one shipped with Staxrip, should be this one, 2.23.1 : I saw in vapoursynth documentation that is supported some LUT's when i was searching for this long time ago but not using vapoursynth i did not pursue in this direction, thanks for the links, I'll try to do a request in the forum thread you linked and see how it goes , this will be really neat if possible with avisynth, have nothing to loose asking :p Thank you

I suspected it :p with rendered 10 bits 422 i had issues, didn't went too far in testing so maybe something is possible or issue was on my end maybe. Don't know for original files in this format, did not searched for samples.

Well, if 'FFmpegSource' as the function name is actually doing something and throwing error messages about video codecs (rather than AviSynth complaining that the function doesn't exist), that's a huge blinking red sign that the version is from the old 1.x series. Not even FFMS2.

vapoursynth; yanak already requested the port . You can even load avs scripts in vapoursynth what type of lut ? there is an old plugin ddcc by tritical for avisynth, but it uses a different type of 3DLUT, not the commonly used cube or 3dl . It might be possible to do some conversion What is the background information ? What is the 2nd pass in ffmpeg (why can't 1pass be the final pass) ? What is the final format goal ? What are you doing in avisynth and after ?

Hello, You can feed FFMpeg with the avs script and apply the LUT, something like this: The avs script (+ the filters you need/want): Code:

To load the audio, it depends on the audio configuration . You have to load each track with FFAudioSource, and specify the track number. You can use mergechannels() to send them or you might want to down mix them to stereo since it looks like you're using 2ch aac For example 4channel mono Code:

The atrack parameter is for discrete audio tracks. You have to use for downmixing.
