h.264 rendering issue...

[meneedit]

Hi guys,

I have been messing around in Sony Vegas trying out different rendering settings on a project to optimize it for youtube.

Recently a friend suggested using h.264 and I had previously heard that it is good for uploading to youtube. I didnt think that I had the h.264 codec until I watched a tutorial on youtube and found out that "MainConcept AVC" is actually the h.264 codec.

Anyway, here is the problem:

When I was rendering it to wmv and a few other formats it came out fine but due to a gaussian blur effect added to the video, youtube was somehow dramatically reducing the quality upon upload.

So I tried out "MainConcept AVC" (h.264) and set it to 1280x720 (as opposed to 640x360 which is what I was doing with other codecs), put the rendering quality on highest, put profile on main instead of baseline (the guy on the youtube tutorial recommended this) and I set the framerate to 25 because apparantely youtube only likes 24 25 or 30 and the highest on h.264 is 29.97.

After the render I checked out the video, and the quality was good but it had a strange lag. I recalled seeing such a lag from my days of using TMPGenc. The lag occurs roughly every second and although it isn't extremely noticable it bothers me ALOT.

My computer is more than capable of rendering videos correctly it's not slow but that shouldn't affect render anyway.

So, my question is: what aspect of the changing the settings would cause this lag? Would it be a framerate thing? or maybe changing the rendering quality?


Any insight would be much appreciated. Thank you all.

Was the video originally shot in ntsc or pal? That could be the issue if you changed from ntsc to pal. Ntsc should be 24 or 30. Pal is 25 (this is for sd not the 60 for hd ntsc and 50 for pal hd that some camcorders can shoot at).

Use the Sony AVC encoder. MC is no good.

Use the Sony AVC encoder. MC is no good.

I shall try that but is the Sony AVC also h.264?

Well I tried Sony AVC and all I got was an error message saying:

"An error occurred while creating the media file untitled.mp4. The reason for the error could not be determined".


edit: I've searched the few threads that exist for this error and nobody has been able to help.

All the settings are the same as MainConcept. it just comes up with that error.
