Frameserving from AviSynth to a NLE program like Sony Vegas

[sp_key]

Hi all,

I need to edit a series of low quality .mp4 files so preserving the quality is very important. The way I am trying to do this is by creating an avs file using the QTReader plugin, then opening the file with VFAPIConv to create an avi pseudofile, edit with Vegas and return an uncompressed avi.

The problems I am facing are the following:

1) Video File comes upside down - (The solution I have found to his is frameserve from Vegas to VDub and use the flip vertical filter but ideally this should not arise from the start).

2) Video comes with no audio. I have not found a solution to this problem yet. I tried to serve it from AviSynth to VDub in order to save the audio and import into Vegas but even though VDub opens the video fine (upside down), and can use the slider to preview it I cannot play it. I get an error message (Couldn't initilize timer, maybe a framerate problem??)

The Avisynth script I am using is:

LoadVFAPIPlugin("C:\QTReader.vfp", "QTReader")
QTReader("C:\myvideo.mp4")

Any suggestion, feedback is highly appreciated.
Thanks in advance

I would open the avisynth script in virtualdubmpeg2 (or whichever virtualdub you favour) using fast recompress mode and save it to a lossless format such as lagarith or huffyuv, then edit in Vegas. No quality loss, and no performance issues.

load them directly into vegas - the latest version will take them

Why didn't I find this? Once again I was thinking too complicated... Oh you know what? I was testing you!

Thanks BJ!
