Vidcoder slower than Handbrake

Dec 5, 2011 at 6:43 PM

Hi Guys,

I love Vidcoder cause it's more user friendly than Handbrake.
But why is Vidcoder slower than handbrake?
In example, while Handbrake takes ca. 27 minutes to encode a 90 minute DVD-Movie by 1-pass constant quality mode,
Vidcoder takes up to 35-37 minutes to encode, with the same settings for the same movie.
I could see that Handbrake runs every time 100% each core. But it seems that
Vidcoder doesn't use 100% all time.

Best regards from Germany

Are you certain you used the exact same settings? Video encoder, video quality, audio encoder and bitrate, advanced options, container? I just did a simple DVD encode at high profile and it took exactly 6:12 in both HandBrake SVN 4368 and in VidCoder 1.2.4. Both hovered around 80-100% CPU usage. You can check the job settings in the log in both VC and HB; it should look something like this:

[21:48:51] job configuration:
[21:48:51]  * source
[21:48:51]    + E:\VIDEO_TS
[21:48:51]    + title 1, chapter(s) 1 to 10
[21:48:51]  * destination

[21:48:51]    + container: Matroska (.mkv)

[21:48:51]    + decoder: English (AC3) (Dolby Surround) (track 1, id 0x80bd)
[21:48:51]      + bitrate: 192 kbps, samplerate: 48000 Hz
[21:48:51]    + mixdown: Dolby Surround

Hi,
thanks for reply.
I'll try this evening, after work, to post the log of Handbrake and of Vidcoder.

You're damn right. It was false alarm by me.
I got this results by an older version of Vidcoder,
testing with newest version works fine and fast as Handbrake.
Got 10 or 20 seconds difference by encoding a 30 minutes episode,
but I think it's due some system fluctuations.
Looking at bitrates shows nearly the same.

Thanks guys, keep up good work!
