Old Premiere had no problem but 2024 version cannot use my AVI files

[polhem]

I have been deinterlacing old DV footage with AVISynth an QTGMC and output an AVI format keeping as much data ass possible.
The format worked fine in older Premiere CS6 but with the new 2024 version, I get the media pending and the main monitor just freezes.

Any help? Any others having problem with new Premiere on various formats?

There are many many hours of footage, so I hope I don't need to deinterlace again..

https://helpx.adobe.com/premiere-pro/using/supported-file-formats.html lists the supported formats.
If you need others you probably should look into plugins like https://www.autokroma.com/Influx which iirc is basically a libav wrapper,...

My guess is that your old Premiere version was a 32-bit application which could use 32-bit VfW codecs, but your new version is most probably a 64-bit application which may require 64-bit versions of your VfW codecs installed to open videos in such a format; or an alternative codec plugin which does not rely on VfW codecs installed in your Windows system.

It would be worth to try.
Can I download 64bit VfW codecs andywhere and how do I get Premiere and AE to work with them?

A 64-bit version of ffdshow, including ffvfw which supports the FFV1 codec, does exist; but it is quite outdated. Better try the suggestion by Selur: Autokroma Influx seems to be quite up-to-date and a specific solution for Premiere.

Ok thanks

Ok thanks!

Two questions, before I commit to buy the Influx plugin:

IF the codec is the problem, would I still be able to play the files in windows using MPC with Klite mega which I have? Because that works fine.
The files seem to work first in Premiere, then they go pending. Preimere also goes incredibly slow when I import the files. Should it not warn for unsupported media instead?

1. test it before you buy it
2. vfw and direct show filters are different things and MPC-XX comes with it's own decoders

Best ask Premiere Support for how Premiere is supposed to do stuff.

Ok so the problem has gone even more puzzling. I just remembered, I have used Premiere 2024 for deinterlaced DVD footage output to the exact same format. The only difference is a bit lower "overall bit rate: 112 Mb/s". And it works fine!
Any new thoughts?
Is the "Overall bit rate : 142 Mb/s" too high for premiere?

No clue -> ask Premiere Support

Influx fixed the problem! What at great "WD-40"-solution!!!
