Handbrake Settings
-----------------------
MP4 H264
Constant Framerate
Preset - Very Fast
H264 Profile - High
H264 Level - 4.1
Constant Quality RF 20
The clip took 2m 33s to convert, resulting size 122mb
ConvertXtoVideo Settings (Custom Profile)
--------------------------------------------------
MP4 H264
Preset - Very Fast
H264 Profile - High
H264 Level - 4.1
Constant Quality RF 20
Software Mode
The clip took 7m 1s to convert !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Resulting size 122mb
(MediaInfo reported it as 'H264 Profile - Main' instead of High which I selected.
NVENC Hardware
The clip took 1m 36s to convert, resulting size 301mb !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Quicksync ConvertXtoVideo gave an error before converting and wouldn't convert.
Conclusion
=========
Why is handbrake a lot lot lot lot lot lot faster than your converter at software encoding?
Why is the NVENC conversion such a big filesize ?
Why doesn't QuickSync work ?
Please fix these annoying problems, Handbrake is FREE.
How about comparing EXACTLY same settings?
You can clearly see that they are not.
Any comparison without same settings is totally useless, oranges are not apples.
Your converter is a complete mess. Sorry to say that but it's the truth. When first starting the program
Please, before creating a post like this one be sure that you're comparing exactly the same things...
You missed an important setting disabled in Handbrake, but enabled in ConvertXtoVideo with Very fast preset.
The deblocking filter is disabled by default is Handbrake and you should try your test conversions with this option enabled...
This filter is always enabled in ConvertXtoVideo because it increase the video quality (reduce video blocks)
It also seems that you're focused on conversion speed but... what can you say about the video quality in your comparison tests?
For the NVENC output size, you need to know that hardware encoding are not as good as software encoding so, if the result is too big for you, you must use software encoding: we can't do anything more
For the QuickSync not working, I will try to reproduce today, but I will need your log files and your Intel CPU specifications.

For your information I used exactly the same settings (that are visibly changeable).
ConvertXtoVideo SOFTWARE converting (custom profile) reports the H264 profile as MAIN even though I have it set on HIGH, yet another bug.

For sure not... do you read my posts?
If yes, you should see that deblocking filter need to be enabled in Handbrake to do real comparison tests.
Handbrake disable it by default, ConvertXtoVideo enable it. It's only a choice and you missed this setting.

Maybe you should add a deblocking filter option to the Custom Profile after all it is a "Custom Profile". I'll try some comparisons with the filter. Maybe you could also add Variable Framerate to the custom profile as this reduces file size ? I'll sort out a log soon.
I converted the same clip (3m48s) with Handbrake using the same settings as before but included 'Deblocking' set to 5.
1 minute 21 seconds (No Deblocking)
6 minutes 15 seconds (Deblocking set to 5) !!!!!
I don't know how much deblocking your program sets at but it adds a HUGE amount of extra time and to be honest I can't tell the difference in quality so can you give the option to turn OFF deblocking in the Custom Profile please ? You can see why I thought your converter is slow because you have hidden settings with no option to turn them off.
So to summarize, can you add the following to Custom Profile please :-
Deblocking option
Variable Framerate
More information in MediaInfo on what settings were used (like Handbrake).
Can you fix the following :
H264 profile incorrectly set to Main when High is selected.
QuickSync not working properly.
can you give the option to turn OFF deblocking in the Custom Profile
Deblocking filter setting is a part of H264 presets.
That mean setting Very fast preset causes Deblocking filter ON.
I will check with VSO staff if deblocking filter can be independent of H264 presets.
You can use the Super fast preset where deblocking filter is disabled...

I'm working on your other problem reports...

But Handbrake doesn't enable deblocking on any H264 preset.
Ideally, the Handbrake program as a whole should be your Custom Profile feature with added extras.

ConvertXtoVideo SOFTWARE converting (custom profile) reports the H264 profile as MAIN even though I have it set on HIGH, yet another bug.
Check on Format settings, CABAC and ReFrames are different. That is enough to invalidate any speed comparison.

You're comparing ConvertXtoVideo's quicksync settings (which can't be changed because its a Hardware encoder) to Software presets. I only added Quicksync to the comparisons to show that it isn't working properly (is Slower than Software encoding).
QuickSync (or nVidia) doesn't support the settings I set because they are Hardware acceleration.
Are you going to add an option to turn off Deblocking in Custom Profile ? I don't see it in v1.5.0.30. Handbrake doesn't use Deblocking on any H264 preset, it gives you a choice so why doesn't yours ? Thanks.
What do you want?
Able to do something to video without remuxing it? - ok, you can RENAME the file, delete or copy it.
Any action you take on video or audio stream, even just changing them from container to another without processing, keeping originals requires remuxing them to new container.

Please read what I wrote correctly.
The custom profile in the latest version keeps remuxing the video even if you turn the option off. It won't re-encode.
I updated to latest beta and tried to convert old mp2 to H264 - no problems,demuxes, decodes, encodes and remuxes just fine video from mpg2 to H264, audio from mp2 to AAC.
The custom profile in the latest version keeps remuxing the video even if you turn the option off. It won't re-encode.
Problem reproduced and fixed, thank your for reporting.
@JJ: I think that the video track has been reencoded / no remuxed inyour case because the source file codec was not compatible/remuxable with the select output container.

Yes, I selected files that clearly must be re-encoded. OP just claimed that it will not re-encode. I proved that it does re-encode.
With conversion log we would have seen what his original files are and what is his target, and that way eliminate some possible causes for this problem.
As remuxing is simply process to combine audio and video streams into target container, it is done every time with every conversion.
