Re Rendering, Video Factory Stumples Badly!

I've already needed to adopt procedures where it is necessary to use other software to both pre process and do post production rendering because of jitters introduced by Video Factory when rendering to AVI and also because VF seems unable to handle its own filters, most notably the HSL filter when applied to a MPEG file, unlike TMPGEnc which has no problems at all.

Now is seems sadly the same is true with MPEG as well when simply adding a couple minutes of new video without applying any filter or adjustments of any kind VF can't handle it. I just tried to modify a finished file by adding a few small scenes. Every scene I added was destroyed when VF added a jitter every few seconds to the new scenes.

The question is WHY?

This is beyond annoying. What good is a video editor if in rendering it screws up the output?

There must be some fatal flaw in Video Factory's rendering engine for these kind of things to keep happening. They do NOT happen in other competing products, so tell us Sonic Foundry why do they happen with your product?

Repeating the same editing in:

VideoWave, Premier, VCDCutter and VirtualDub, no jitter was introduced using the same system and the same file.

Again, I ask WHY does Video Factory screw things up?

I'll agree that VF's render "features" need some polish.

It seems like VF's rendering options are deliberately hobbled so we have yet another reason to buy Vegas (as if it's numerous other features like unlimited tracks, keyframable filters, chroma keying, 24/96 audio support aren't enough). However, I think SF hobbled it to much compared to rivals like Aist MovieXOne, Magix Video Deluxe and Ulead Video Studio.

The VF templates are nice but I found you quickly outgrow them and wish for more control.

More Quicktime options along with the option to make SVCD and (simple) DVD's would be much appreciated.

Also, I noticed a decline quality of video apps that rely on DirectX 8 (or more accurately DirectShow). Developers seems to blame Microsoft's bugs (unfortunately, you have to use DirectShow if you want XP compatibility) although I think developers' unfamiliarity with the new system contributes as well. Perhaps the imminent release of DirectX 8.1 will help things. I hope so since DirectShow (and WDM drivers) seem to suck real bad right now.

Other things that need polishing include:
1) The vidcap program. This seems to be the number one source of problems.
2) The trimmer. We all miss it when it's gone, but quite frankly it not as useful as it should be.
3) The Ligos MPEG encoder.

Nevertheless, as a whole, I find VF to be the best editor in it's price range and I have to give credit to the folks at SF for being so receptive to suggestions (and a little criticism).

Hear Hear on all three counts!

I'd go for a trim feature myself. When I capture tv stuff, it would be nice to cut off the last 2 seconds of the video without having to re-render the thing. Those commercials sneak up on me while I am capturing.
