VP23 - 10 minute render for 40 second clip?

anthony-chiappette wrote on 11/7/2025, 5:41 PM

I rendered a part of my video to see how the animated (flowing) text would look. This was 40 seconds out of the video, but took 10 minutes to render. Is it normal for the type of text animation I've used to take that long to render? most of the videos I render take about 1/2 the time of the video to render, but this is excessive.

EDIT: It also shows it rendered 148MB, but the resulting MP4 file is only ~48MB

@anthony-chiappette On your screenshot it's difficult to see what could cause the slow rendering: project resolution, framerate, etc, what is on all those "empty" tracks?

The typing text animation needs ofcourse some rendertime, on my PC it takes about 2 minutes to render a 40 second typing text animation in 1080p50 (probably also very depending on how much characters there are used, quite a lot in your example).

The shown expected size of the MP4 file is just a guess, the final size depends hardly how much movement there is in the video, since there is hardly movement in your video (just the typing text) the final size could become much less than the expected size. I got for my text animation a guess of 97 Mb and the result is just 2,3 Mb.

@anthony-chiappette VP22 - Just for comparison. I set it to 1080p50 like 3Point's

Using the default text on the type-on Title 04, MP4 AVC (NVENC), it took 1.48min to render 40secs of text on a png. Rendered file size was 46.5mb even tho the render box says 96.28mb. (same speed using Mainconcept)

You can see in Taskmanager Vegas doesn't use much of my pc.

----------------

MP4 HEVC was the same time but the file size was 19.9mb even tho the render box still says 96.28mb

Just did another test, the renderspeed depends a lot of how many characters are used.
