MOV (SQ3V) problems

[miamicanes]

Another fun roadblock... I have a bunch of .mov files...

* They play fine with VLC Media Player. It identifies the media as Stream 0=MPEG AAC, Stream 1= SVQ-3 (Sorenson Video v3) (SVQ3), 480x270, 29.97000

* Windows Media Player (Win7's default) complains that there's no video stream. It's just a hunch, but I have a sinking suspicion my mad codec installation and deinstallation earlier this weekend might have screwed it up.

* If I try to load it into VirtualDub through Avisynth via FFmpegSource2, it says FFVideoSource track contains no frames.

* If I try to load it into VirtualDub through Avisynth via DirectShowSource, I get the same error. For the record, I've never gotten DirectShowSource to work properly with *anything* since I installed Win7-64 last week

* TMPGencX4(trial) chokes on them.

* Unsurprisingly, my Seagate Freeagent Theater chokes on them, too (allegedly, it supports .mov, but I've personally never gotten anything besides DVD ISO files and MPEG-2 files to play on it). This player is ultimately the reason why I'm trying to convert them from .mov to MPEG-2 with TMPGencX4.

I tried using VLC to convert the mov to AVI with Lagrath codec (Huffy doesn't seem to like Win7/64, either) and ended up with a file that was 560mb (vs the original 80mb .mov file), was unplayable by VLC, had neither audio nor video when I tried to play it with windows media player, and TMPGEnc choked on it.

Any ideas for what to try next?

(for what it's worth, since my post on Friday, I figured out how to get TMPGenc to work with .mp4 files using Virtual Dub + Avisynth2.5 with FFmpegSource2 to convert them to AVI using Lagrath first... this is a new problem)

do you have quicktime or quicktime alternative installed ? If it plays in quicktime, you can use qtinput() in avisynth

do you have ffdshow installed and svq3 enabled in the configuration? use win7dsfiltertweaker . If you have directshow working with ffdshow and configured properly, you can use DirectShowSource()

so it plays with vlc, but vlc can't convert it ? doesn't make sense. Probably because you don't have lagarith installed for win7 x64

I'm willing to be you can convert it with ffmpeg as well ( or some GUI for it, like avanti, winff )

You might be right, but since FFVideoSource didn't work, I wouldn't bet any serious money on it.

I had to install the 32-bit version of Lagarith, because otherwise Avisynth went down in flames, and there doesn't appear to be a non-experimental 64-bit version of Avisynth. So, I threw in the towel, uninstalled everything on friday night, reinstalled only 32-bit versions, and finally managed (around 3am Saturday) to get FFmpegSource2 to work.

Starting with the basics... any idea how to fix (or even diagnose) the problem with Windows Media Player and audio playback (it seems to be incapable of playing files ending with .mpg that are MPEG-2 with mp3 audio, but does seem to play audio for .m2s files with AC3 audio)? I know that's not directly related to my problem, but I suspect getting a grip on that is the first step to getting DirectShowSource to work (specifically, I suspect that anything that doesn't work with WMP won't work with DirectShowSource, either).

GraphEdit or GraphStudio is a good tool for investigating problems like this.

That's right.
