HELPFUL TIP: Some MKVs may contain variable framerates, if you have problems with the video appearing to be shorter or longer than it is supposed to be with varying speeds then try using LWLibavVideoSource("video.mkv", format="YUV420P8", fpsnum=24000,fpsden=1001), this will force the video to be opened using 23.976 frames per second.Īlternatively, the most accurate way of handling M2TS, MKV, or MP4 containered videos from Blu-ray discs would be to use DGDecodeNV.
Here are a few examples of what a script would look like using this function: It is important that you DO NOT close the program and allow 2-5 minutes for the index file to be created.

IMPORTANT: The first time a script using these functions is opened up it must read the entire file and create an index file which will cause the software opening the script stop respond. This function, which is part of LSMASHSource, creates an index of the video data so that it can be handled with frame accuracy like an AVI. When it comes to videos that are in M2TS, MKV, or MP4 containers, one of the best methods of importing the video data is to use the function LWLibavVideoSource. By handling video this way you must also specify which variable containing video data for functions to use and which variable the script will return (Ex. This way of handling video makes the script much more complex and is not always needed for handling basic video filtering.
C:\videos\video.avi).Īnother method to handle video in AviSynth is to import a video clip and store it as a named variable, which will allow you to open multiple clips in one script.

If you wish to import a video from another directory you will need to specify the full path to the video file (ex. NOTE: It is recommended that you create your script in the same directory as the video you intend to import into the script. For the sake of this guide I will refer to a video not stored in a user defined variable as a floating video. AviSynth works by processing the script starting at the top and working its way down so when using this method the video output from one function will be the source for the next. Please don't sue us.One way to import and process video through AviSynth is to dedicate the entire script to one video source by not specifying a variable name for it to be stored as (Ex.

I’ve tried opening the MKV directly in VirtualDubMod and it just crashes, and I’ve tried all this with the non-remuxed file with all the audio tracks and chapters included, too.Īuthor ChainsawAsh Time 2 5:14 AM Post link The format is not supported.”Īudio returned: “DirectShowSource: couldn’t open file D:\JediDesp.mkv:ĭirectShowSource(“D:\JediDesp.mkv”, fps=23.976) Video returned: “DirectShowSource: couldn’t open file D:\JediDesp.mkv:Ĭannot play back the file. So now I’ve made an avisynth script to open my MKV in VirtualDub to convert, but every time I try I get this error:ĭirectShowSource: Could not open as video or audio. So I used mkvtoolnix to make a new MKV with just the 2.5 video stream, used tsmuxer to demux the DTS-HD track I’ll be using, and used eac3to to convert the DTS-HD to WAV. I’m starting with the Harmy 2.5 since that’s gonna be my primary source (this is for a proof-of-concept rough restructuring of ROTJ as discussed in the edits section), so I don’t know yet if I’ll have the same trouble with the Blu-Ray (haven’t even ripped the discs to my hard drive yet). I’m trying to convert a few different files (Harmy’s ROTJ v2.5, the 2011 ROTJ Blu-Ray, and the 2011 Blu-Ray deleted scenes) into Lagarith using VirtualDub. It’s been a while since I’ve done this, but I don’t remember having this much trouble. JEDIT: Problem solved by installing the K-lite Codec Pack.
