VD2 Image Sequence to AVI issues

Hi there,

Posting mostly for record/benefit to others, although some things are still unclear, but mostly I'm fine

So, following this page:

http://www.virtualdub.org/blog/pivot/entry.php?id=34

Attempted to load 20 frames, sized: 5184x3456 and save as n AVI..

Got this error:

Code:
x264vfw [warning]: frame MB size (324x216) > level limit (36864)
x264vfw [warning]: DPB size (4 frames, 279936 mbs) > level limit (2 frames, 184320 mbs)
x264vfw [error]: x264_encoder_open failed
Figured it wants size of 3240x2160 (based on error message), so reduced all images to: 3240 x 2160, then Ctrl-W (close video file), and loaded the reduced images as a sequence, this time it gave this error:

---------------------------
VirtualDub Error
---------------------------
Cannot start video compression:

An unknown error occurred (may be corrupt data).
(error code -100)
---------------------------
OK
---------------------------

x264vfw [error]: x264_encoder_open failed

Attempted other sizes, in the same fashion, and it kept failing as above.

Decided to CLOSE the VD2 interface, and launch a new one. BOOM, all resolutions up to 3240x2160 started withing fine!! Then kept working with 3240x2160; went to 30 sequence photos, then it started failing again, so trimmed back to 2400x1600, and all went OK even with 30+ images.

VD2 produced a ~14MB AVI (with an mp3 audio track).

Plays fine in Media Player Classic, BSPlayer.. However:

On VLC 2.2.x it shows only first FRAME, and plays audio until the end...
Upgraded to VLC 3.0.4, plays, but no audio and no video, just time bar progresses forward... I suspect VLC is not aware of this format, not sure..

Hopefully this helps someone

Stormy.

> frame MB size > level limit

You probably used fixed encoder level in x264 setup. Make sure "level" is set to auto and use x64 version to work with big image sizes.

You can use vd' resize filter instead of resizing source images.
