.mp4 & .flv files not working in Sony VegasPro timeline

[RMK 3]

I’m putting some videos on my iPhone to view offline and can’t figure out my problem.

I’m taking some flash video off a website using SpeedBit Video Downloader which creates either:

1. a .mp4 file that will play in QuickTime, but not work with SonyVegas Pro8c timeline or iPhone transfer

2. a .flv file that will play with VLC Media Player, but also not play in the Sony VegasPro8c timeline

In either format, SonyVegasPro8c only has sound but no picture. I’m using a PC for the above and either file will play OK in their native video player.

Any ideas?

A-legal copy of Vegas? DVD A installed?
B-mp4 is just a container. There are various methods of creating an mp4. Vegas should be able to read it.
C-Vegas will only read the FLV if it's flash 5 or older in compatibility.

In your Vegas prefs, you might be sure that "ignore third party codecs" is not checked.
It may well be that the Speed Video Downloader isn't making a compatible file.

A. yes, legal/licensed copy of Vegas (inclusive of your fine VASST discs)
B. understood; I’m not certain what the SpeedBit software outputs
C. was checked; I unchecked it, restarted Vegas, but still no joy

I notice for these files, when I drag them from the Explorer window in Vegas to the timeline, only an audio track moves instead of the usual video and audio.

I’ll assume it’s a problem with the SpeedBit downloading software and will try something else. Vegas has always been able to read anything I’ve thrown at it
Any suggestions on flash video download programmes? There are loads of them, but I’m not trusting of downloading random software I’ve never heard of.

Thanks for the help.

Do you have Quicktime installed?

Yes, and Quicktime will play the output .mp4 files perfectly. However, they will not transfer to iPhone via my uTunes, so my next idea was to use Vegas to convert either the FLV or MP4 into the MainConcept AVC/AAC (.mp4)

I'm thinking you need to use another convert program, seems like Vegas doesn't like that codec.
Try this;
Set a system restore point and download the Klite codec pack. Then try the mp4 (vegas won't open the FLV) on the timeline.
Klite sometimes is distributed by bad sites, so the restore point should let you get back to where you were before the install should it not work.

just used Keepvid.com to download a coupla files from YouTube and they opened as expected in Vegas 9e.
