Rendering Nightmare

[Sabrina Watson]

I can’t do that because two of the clips together that I rendered the other day did ‘not’ jerk. That also was a bit of the video that lacked music. It can’t be the mp3 files that are causing the jerking, correct? Because the sound itself plays smoothly.

With Divx 6 installed and FourCC codes changed to DIVX,
I suggest you load your camera clips into VirtualDub one by one and save them as uncompressed AVI files (John Rofrano instructed it before but, if I didn’t get it wrong, you have used Vegas instead of VirtualDub to uncompress them.)

Move your original video files to a different folder, uncompress them using VirtualDub, save them with the original file names to the folder where your original files used to be. After that, when you run Vegas and load your project, it should automatically replace the new video clips with the offline ones.

I’ll give it a shot, but my media is no longer offline, it did re-appear as online, but I did not do the whole Virtual Dub thing–at least I don’t think I did.

Let’s see if this works.

[Sabrina Watson]

Okay, I used VirtualDub the way you both told me (finally I realized I didn’t do that). Once I was finished I checked with that fourCC program to see if I had to turn my files into DIVX and I didn’t–they all were still the way I made them. So I rendered a part of the video and…the same thing happens.

Here’s one ‘jerking’ clip. There’s a bunch more that do the same as this. They either jerk, they skip a bit, or they stall and the process to jerk/skip.

Did you use VirtualDub to create uncompressed AVI files? If you check them with the FourCC program, the Description Code should be DIB and the Used Codec should have nothing in it! (because uncompressed files don’t use codecs) Is that what you saw?

The clip that you posted looks exactly like what happens when Vegas tries to render DivX files. I’ve seen it before and I can’t believe that happened with an uncompressed file.

Please check that the files on the Vegas timeline are uncompressed (i.e., right-click | properties, check that Format: Uncompressed) and that they don’t have this jerky problem.

They do they say that DIVX is the format, but I did go through each clip while in VirtualDub. Am I supposed to select certain options/preferences in VirtualDub before I save as avi? I just clicked open, then I selected the files (one by one) and then saved them to avi. Was I not supposed to do that?

[John Rofrano]

Yup, that’s exactly what you were supposed to do. Are you sure you are using the saved files? While in VirtualDub, go to Video | Compression… (Ctrl+P) and make sure (Uncompressed RGB/YCbCr) is highlighted. Then make sure Video | Full Processing Mode is checked. Finally, select Save as AVI…. Now check the resulting file. It should be a LOT larger than the DivX version in size. It should NOT have a FourCC of DivX because it is uncompressed.

I checked all of that and all is well except when I took a look at the properties of the files in my video folder, it still showed DivX. Why is that happening if I’m following the right directions?

[John Rofrano]

I don’t know. It’s impossible. Rendering uncompressed removes the codec. The DivX 4CC should not be there. What is the size of the original file and the uncompressed version?

I don’t have the original files anymore. I mean I do on my memory card inside my camera, but I don’t on my computer anymore because I used them in VirtualDub.
