#Ffmpeg filter frame export code

You're making a 'smart rendering' editor that only re-encodes specific sections, correct?Īvisynth frameserves uncompressed video. LigH is suggesting avisynth for the scripting and filters - the transforms like rotate, color correction etc. As far as i can determine, imagewriter is the only way to create an image from a video ? Now it is suggested to use ffmpeg since it has avs support? Hmmmmm If you read my last post it was suggested to me to use avisynth instead of ffmpeg. I just thought I might have better results if I used: If I add free rotate avs script to the ffmpeg, it causes errors such as parsing not seen by either sscript by itself. I cut the frst segment losslessly and send it to the editing portion where it crops, stretches ,adjusts brightness, contrast, adds subs, and scrolling text and more, it works. I have a video that has 2 segments, the first which has been squashed vertically. Right now everything works as planned except free rotate and zoom.įor instance.

Just thought it would cut my code and work area down. It's not a big effort to create the video and then create the final from it with avisynth. It would be nice if it is possible to edit the video and send it directly to Avisynth instead of creating an intermediate video file. Crop and rescale to original size) as well as others. The problem is making all functions work as one script, I find it is much better if I create a video file and run it through avisynth for some functions such as stack, zoom, stretch a resolution (e.g.

The also does most everything I need or could want for that matter. I have written (work in progress) for a frame accurate cut and merge progream that recodes only what it needs.

I am not familiar with vaporsynth but I will definitely check it out as a p ossible subtitutes in some, I can of course use avisynth for almos everything but I find it easier in some functions to use FFMPEG.
