MP4 in Zarx?

[Artystic]

Sorry if this has been posted before, but I couldn't find anything using the Search...

I'll start off by saying I'm a total n00b at this so if there's an obvious solution please don't be abusive ^^"

So basically, I downloaded the newest version of Zarx and tried choosing several MP4 files as the "Input Video" but each time it says:

DirectShowSource: Could not open as Video or Audio.
bla bla [File Location]:
Cannot play back the file. The format is not supported.


I know for definite the file is supported, as I used the same render settings in Vegas as my friends...

Any help is appreciated.

Something i did not get from what u just said, Is your exported video an .AVI or .MP4? And make sure u installed AVIsynth

If I read your post correctly then the problem is that you dont put mp4s in Zarx, you put Avisynth files into Zarx and it exports it as a higher quality mp4 file. Which is why you are getting the message “Cannot play back the file. The format is not supported”.

1) If you don't have AviSynth 2.58 installed yet, install it and try again (although with it actually giving you a warning about DirectShowSource, I assume it is installed).

2) DirectShowSource works by using, obviously, DirectShow's decoding filters. If you don't have Haali's Media Splitter, an H.264* decoder (ffdshow or CoreAVC, take your pick - preferably I'd go with ffdshow, but now that CoreAVC 2.0 is out the weightp 2 issue shouldn't be a problem anymore), and an MP3, AAC, or AC3 decoder, then it can't do squat. You probably can't play back said MP4 files in Windows Media Player either, because WMP uses DirectShow (maybe Media Player Classic as well, although it has some internal splitters and decoders it uses).

*I'm assuming H.264 simply because of prevalence; it's totally possible to use MPEG-4 ASP (i.e. Xvid) in MP4, and that possibility was around long before H.264 came onto the scene.


So, to answer #2, install Haali's Media Splitter (not linked to the main site only because it's down right now), and ffdshow (I go with clsid's generic builds, but feel free to choose a different one if you want), and try again.

I think the big question here is, WHY are you recompressing an MP4 file?
If you exported out of vegas an an mp4, and then you compress it to mp4 again, you are going through 2 stages of lossy compression, which will hurt the quality of your video.
You should export an uncompressed video out of Vegas.
